| “ | The duty of solving cases that everyone else has abandoned falls to me, the man with the highest grades in BLUE's history | ” |
—Ron Kamonohashi[source] | ||
Ron Kamonohashi (
He is a sixth-generation descendant of Sherlock Holmes and a ninth-generation descendant of James Moriarty.[21]
Physical description[]
Ron has deduced something.
Ron is a thin, slender man with disheveled black hair and sky-blue eyes which are usually hidden behind his bangs. However, when he deduces something, Ron pushes his hair to the side and reveals his eyes. Whenever Ron pressures a murderer into killing themselves, a strange glaze lays itself over his eyes.
He inherited his height, build, and eyes from his father.[22] He is also quite athletic as he works out every day for four hours.[23]
Ron at BLUE.
Before the Bloody Field Trip Case five years ago, Ron's hair was short and neatly slicked back.[24] According to Totomaru, he looked quite dapper then.[25] The incident also left Ron with a large scar on his neck that looks like a "96."[26]
Ron often wears his regular loungewear which consists of a white shirt, black cardigan, gray sweatpants, and black slippers. He also owns a lot of clothing that depicts platypuses[27][28] or features the names of Japanese sweets: anmitsu kanten,[29][30] kuromitsu,[31] yomogi mochi,[32] mochigome,[33] sakura,[34] kashiwa mochi,[35] and mochi.[36]
Personality and traits[]
Ron is very passionate about solving mysteries. He possesses many skills and qualities needed to be a detective, e.g. he has outstanding deductive abilities[37] and an excellent memory.[38] However, Ron is quick to anger,[39][40] and his fixation on cases makes him apathetic to everything else, standoffish and rude to other people,[41][42] and easily bored when he has no cases to solve.[43] Although he hated people even as a baby,[44] Ron still cares about other people's lives.[45] Thus, when he lost his detective license after the Bloody Field Trip Case and was branded a murderer, Ron became depressed and spent the next five years in isolation.[46][47][48]
After Ron meets Toto, he gradually begins to change[49] and warm up to others,[50] though he still likes using people for his own gain.[51][52]
Moreover, Ron has various idiosyncrasies. For example, Ron lies down next to corpses and "talks" to them, swearing that he will be their avenger, while he examines them.[53] He does this to pay them his respect. He also likes to disguise himself when he accompanies Toto on cases,[54] and sing "Kamo-Kamo" when he is happy.[55] According to Kiku, Ron has had a "crazy" personality since before his expulsion.[56]
He loves brown sugar syrup[57] and puts it on everything he eats whenever he can; he also drinks black sesame paste to prevent anemia.[58] Ron knows how to make a wide variety of brown-sugar-flavored foods[59][60] and drinks.[61] He even has a brown sugar business card.[62]
Ron is very fond of platypuses. Not only does he get upset when someone mistakes them for ducks,[63] he also owns several pieces of clothing[27][28] (i.a. swimming accessories)[64] and many objects (i.a. a handkerchief,[65] a hand-puppet,[66] and a mug)[33] featuring them. There is also a platypus in the logo of "Kamonohashi Sweets."[28]
Biography[]
Early life[]
Baby Ron
Three-year-old Ron
Ron always believed that his father died of an illness before his birth, and he was raised by only his mother.[68] However, Eliot was still alive and involved in his son's life when Ron was a child.[69] His father taught him all about crime[70] so that he would have the strength to live the life he wants, rather than one bound by the Holmeses or Moriartys.[71] When Ron was six years old, he witnessed Eliot getting shot to death by two henchmen of the M. Family; it was the saddest thing that ever happened to him, and he repressed the memory for 17 years.[72]
Later, Ron enrolled in BLUE and became part of its 87th training term.[75] There, he met Kiku's son Kei Moore[76] and got to know Kiku for that reason.[77]
Already in his first year,[78] Ron became the student with the highest grades in the academy's history[79] and was able to solve a case no other student had before. Everyone expected greatness from him, and Ron pledged that he would use his talent to be a lifelong detective.[80]
Once, Ron snuck into BLUE's autopsy room to take a look at a real corpse. When there was none, he laid down on the autopsy table for a nap and later woke up to Hirsch talking on the phone. Ron pretended to be asleep until Hirsch attempted to dissect him; he then ran away, and Hirsch chased after him with a scalpel.[81]
Bloody Field Trip Case
When he was 17[82] and halfway through the school year,[83] Ron was chosen to participate in a practical exercise that entailed working with Scotland Yard to find the hideout of seven murderers. Having already solved the case, Ron occupied himself with a difficult locked room assignment until the practical exercise.
Ron handed in his solved homework[89] and rushed to the crime scene where he blacked out mid-fight against the criminals.[90] Meanwhile, an imposter wandered the school disguised as Ron and openly went to the hideout a day later. The impostor killed the assassins, dressed Ron in his bloody uniform, and then quickly handed Ron the knife after stabbing himself in the chest.[91] Not long after Ron regained consciousness, the police discovered him, covered in blood and holding the murder weapon.[92]
Ron was completely calm when he was found,[93] but panicked, kicked, and screamed when he was arrested.[94] Because of his injuries, Ron was first taken to a hospital. During the three hours he was there, Ron received his "96"-scar and his Kill on Sight ability.[95][96]
Because Ron had no recollection of the period thirty minutes before and after the incident which became known as the "Bloody Field Trip Case," the investigators concluded that it must have been a case of temporary insanity. Ron avoided the death penalty, but his detective license was revoked and he was expelled from BLUE. From then on, he was banned from investigating any cases.[93]
Ron moved to Japan, and his mother appointed him as the new manager of the Maison du Kamonohashi.[14] Subsequently, Ron isolated himself from the world.[97][98] To give him company, Kiku eventually gifted him a cat.[77] Over the years, Kiku also sent young detectives to Ron, hoping that he would find a partner in one of them and be able to resume his detective work, but Ron only broke their noses and sent them away.[99]
Metropolitan Serial Drownings Case
Five years later, Totomaru Isshiki knocks on Ron's door because he needs his help. Though initially unwilling to hear him out, Ron invites Toto inside when he tells him that Kiku sent him. Toto asks for his help in the Metropolitan Serial Drownings Case, and Ron declines, as he does not do any detective work anymore. However, when Amamiya calls Toto, and Ron overhears that another victim was discovered, he gets the insuppressible urge to solve the case, even though he knows he should not because of his incurable "fatal flaw." Toto assures him that he will ensure nothing bad happens, and they head to Kazahana Park.
There, Ron examines Okamasa's corpse and deduces that he is a businessman and that he was drowned and robbed. Toto then hands him a map that marks all the places where the victims were found. After briefly studying the map, Ron solves the case and then takes Toto shopping. He dresses him in horrid designer clothes before sending him to a barber for a haircut. Despite his confusion, Totomaru agrees, and Ron waits outside while Toto heads inside.[100]
Just when the barber is about to drown Totomaru, Ron picks the lock and reveals him as the serial killer. The barber filled the sink with oxygen-deficient air, making it easy for him to drown his victims. Upon being confronted, the barber runs away, and Ron and Toto chase him to the roof. The barber confesses and says he did it for revenge and money. As soon as he hears that, Ron's ability is activated, and he pressures the barber into jumping off the roof. However, Totomaru manages to grab the barber at the last minute, impressing Ron. Ron then saves both Toto and the barber from falling.
Later, they return to the Maison du Kamonohashi where Ron enlightens Totomaru about Kill on Sight, his strange ability that allows him to persuade murderers into committing suicide. Because he cannot control this power, he needs Toto's help: Ron will solve Toto's cases, and Toto will support Ron and pretend to be the one solving them.[101]
Locked Room Piggy Bank Theft Case
Sometime later, Toto visits Ron again, and Ron tells him that he used to be BLUE's top student before he was expelled after being accused of murder. Because he lost his detective license as well and cannot solve cases without it, he needs Totomaru's assistance. Toto informs him that he is his division's "dead weight" and only receives small, unremarkable cases; today, while his colleagues are looking into a corpse found by a river, he has to handle the Locked Room Piggy Bank Theft Case. Ron, however, is happy to take on any case, no matter how big or small. They then head to the crime scene.
There, they are greeted by the younger sister who shows them her piggy bank and explains that she was away two days ago. When she returned, the piggy bank had become lighter; before, it used to be as heavy as a statue. She and her older sister have also been receiving weird silent phone calls lately. The older sister then arrives and testifies that she returned home earlier than the younger sister. Because the older sister insists that the piggy bank weighs the same as before, they decide to break it open, revealing significantly fewer coins than before. Ron orders Totomaru to send the coins to forensics and says that they will meet up later because he needs to take a walk.
At the river, Toto receives a call from forensics: Only the older sister's fingerprints were found on the coins. Ron and Toto then join Amamiya by the riverbank where she and her subordinates are investigating. After Ron examines the corpse, he makes Toto present his deduction: The piggy bank theft and the river corpse cases are connected. The dead man is the older sister's stalker who she killed in self-defense with the piggy bank. She replaced the broken piggy bank and transported the body to the river in a suitcase.
The older sister confesses, and Ron compels her to drown herself in the river, but Totomaru can save her.[102] Later, Ron and Toto meet up at the Maison du Kamonohashi, and Ron praises Toto's performance and declares the day "Puppet Establishment Day."[103]
Benizome Hot Springs Murder Case
Ron calls Toto to come to a supermarket because he needs him to pay for his groceries as the cashier does not allow him to open a tab. After Toto pays, Ron receives a lottery ticket and wins a weekend trip to the Benizome Hot Springs for two people.
Later, they head to the Benizome Annex where they are greeted by Spitz Feier. Ron and Toto immediately go to the men's bath, and Ron tells Toto about a legend he read in the pamphlet they received from their taxi driver: Apparently, the hot springs received its name after a girl was sacrificed and her blood dyed the water red.
Afterward, Ron and Toto play ping-pong, and when they lose their ball and wade, in vain, to find it, they return to the men's bath to warm themselves up. A moment later, Amamiya enters the men's bath and quickly leaves when she realizes her mistake. That evening, Toto and Ron play The Game of Life with a few other guests—Michiyo and Sachiko's husband—in the Crimson Room until 2 a.m. Amamiya is not present because she went to bed early.
The next morning, a staff member discovers a corpse in the women's bath: It is Sachiko who went to the bath alone at around 10 p.m. Suspicion immediately falls on Amamiya because she is the only one without an alibi, but Ron declares that she cannot be the culprit,[104] and that Toto will prove it. "Toto" already deduced that the murder was modelled after the Benizome legend; Amamiya does not know it and, thus, could not have committed the crime.
Michiyo testifies that she saw mist rising from the river after dinner, and Ron discovers the lost ping-pong ball in a dam created from leaves, branches, and a rain gutter. After he and Toto also find a bathmat, and Amamiya reminds them about the embarrassing run-in, Ron solves the case.
When the local police arrive, Ron and Toto retreat to their room to discuss the case. Realizing that Spitz is spying on them, Ron punches against the wall. Afterward, Ron and Toto gather everyone in the women's bath, and Toto reveals what happened: Sachiko was killed by her husband. He redirected the river's cold water into the women's bath, placed a bathmat over the bath's entrance, and put red leaves in the water. When Sachiko entered the bath, she tripped because of the mat and fell into the water; the sudden temperature change made her die of a heat shock.
While the husband confesses to the crime and that he cheated on Sachiko with Michiyo, Spitz drags Ron away to the forest where he ties him up. Totomaru discovers them there, and Spitz reveals that he is a BLUE instructor and was sent to find out whether Ron is engaging in any detective work. However, he assures Ron that he will lighten his punishment if he admits everything, but Ron sees through his ruse and the true reason why Spitz sought him out: He needs his help.
Spitz admits that he needs his help locating his missing brother. Ron declines as he does not trust him, but Toto vouches for Spitz. Touched by his effort, Spitz says he will do his best to gain their trust before he leaves. Ron then notes that Spitz might be useful in the future.[105]
Hand Collector Killer Case
After Ron located Toto with Spitz's phone, he invades the crime scene of the Hand Collector Killer Case in disguise.[106] There, Ron encounters Omito Kawasemi and Yamane, and although Kawasemi is displeased by Ron's presence, he reluctantly allows him to stay as he does not seem to be a "half-assed" civilian, at least.
Toto then informs Ron about Kawasemi's accomplishments, and Ron becomes jealous and determined to solve the case before him. He forces Yamane to brief them: The Hand Collector is notorious for stabbing his victims in the heart and, as his name implies, cutting off their hands. Last night, Yamane and Kawasemi could corner the Collector, but he managed to tackle Kawasemi and run away. Curiously, the dead man that was discovered in the transporter is the man they thought to be the Hand Collector.
Excited, Ron goes to examine the corpse and notes the body's under-dressed state and the tattoo on the arm stump. Yamane clarifies that it is a bird tattoo and that he saw it last night while handcuffing him. Ron then tricks Kawasemi and tests his reaction time: He could effortlessly dodge Toto and, thus, must be lying:[107] The killer could not have easily tackled him.
Kawasemi admits that he was lying, but only to shield Yamane. He was there when the culprit escaped, and Kawasemi realized that the situation must be unsettling Yamane: After all, a button was missing from his orderly partner's sleeve. Ron then points out that Yamane is missing a button again which sends him into a panic; only when Ron says he has it, does Yamane calm down, relieved to know that it is "here this time." Hearing his words, Ron solves the case.
Afterward, Spitz calls from the room of the corpse in the truck, Minoru Mushanokoji. He found the three victims' hands in a fridge, proving that Mushanokoji is indeed the Hand Collector. Ron then tells Toto his deduction to present Kawasemi and Yamane: Mushanokoji committed suicide last night after Yamane and Kawasemi cornered him. Yamane found the body and removed Mushanokoji's blood-stained jacket, cut off his hands, and placed him in the truck so that he could report that Mushanokoji ran off with the handcuffs. In reality, Yamane had lost them but was too frightened of Kawasemi to admit it. Kawasemi is horrified and apologizes to Yamane for putting so much pressure on him.
Kawasemi later approaches Ron and Toto: He has seen through their relationship, and it made him see Toto in a new light because Ron can only display his abilities with Toto's help. Kawasemi adds that he is looking forward to their next joint case—which he will solve, not them. Ron, on Totomaru's behalf, accepts the challenge.[108]
Live Broadcast Murder Case
After years of complete isolation from the outside world, Ron purchases a television, and when Toto visits him, Ron invites him to watch his favorite show with him: "Lie or Truth? ESP!!"
In today's episode, genius neurosurgeon Mofu Usaki faces off against self-proclaimed ESP Dankichi Torage. Torage claims that he can control someone's brain by only using writing. He picks a volunteer from the audience, and after the host Onoyako puts voice-cancelling headphones on him, Torage begins to write words on panels. He holds them up; as soon as the volunteer reads the command, his brain will obey and execute the order, and the man will be unable to fight back. And indeed, it seems to work: The volunteer jumps and runs when he reads the words on the panels. Mofu objects, saying that she analyzed the man's movements and found out that he is the same volunteer Torage chose the last time. This means they are working together, and the demonstration is a farce.
This enrages Torage and, to prove her wrong, he writes "death" on the next panel. When the volunteer reads the word, he collapses. Torage checks his pulse and pronounces him dead right before the live broadcast is cut off.
Ron and Totomaru hurry to Donut Television. There, Ron examines the corpse and gets an autograph from Torage (oddly, he uses the thick end of his marker to write his name) before he and Totomaru speak to Mofu. She tells them that the volunteer was killed with a nerve poison, and Ron agrees, saying that he spotted a puncture wound on the victim's neck that must have come from the poison needle.[109] Mofu also informs Ron and Toto that the victim let out a groan when she massaged his heart; his breathing stopped again right afterward. This is the final piece of information that allows Ron to solve the case.
Ron and Toto then gather everyone, and Toto announces that they will re-enact what happened earlier. Mofu will be the test subject this time, and Toto will use Torage's marker and cards. When Torage is reluctant to hand the marker over, Mofu goes to get it from him and trips in the process. The marker lands in-between other pens, and Mofu picks it up.
During the re-enactment, everything happens like it did before—Mofu even collapses when she sees the final word. Toto reassures everyone that she is not dead: When he showed the panel to the audience, it read "death." Before he showed it to Mofu though, he turned it upside down. "Death" turned into "sleep." The same occurred earlier, and when Torage checked the sleeping volunteer's pulse, he killed him with the poison needle he hid in his marker. Torage confesses that the volunteer was his assistant who was threatening to expose him if he did not give him 90% of his profits.
Kill on Sight activates, and Ron pressures Torage to stab himself with his marker. When Toto rushes to save him, the tip touches his skin. And although they quickly realize that Mofu picked up the wrong marker earlier and Toto was not poisoned at all, the incident still shakes up Ron. He regrets resuming his detective work because Totomaru nearly died because of him.[110]
Ron leaves the building, and Toto follows him. He convinces him not to quit, saying that he will not die that easily and that he believes in Ron. Then, Toto surprisingly receives an invitation to a party at the Nandan Observatory on Nandan Island. As soon as Ron sees the invitation, he wants to come along.[111]
Island Observatory Murder Case
Ron tells Toto that he wants to accompany him because Nandan Island is famous for its brown sugar syrup; he also wants to distance himself from cases for a while. Toto agrees to take him along.
Three days later, the observatory director Takumi Jumonji drives Ron and Toto on a boat to the island. He informs them that he invited Totomaru as a security measure because, ten years ago, there was a terrible incident at the observatory. However, before Jumonji can elaborate, Ron cuts him off, not wanting to hear anything about any cases. On the way, Ron also expresses his wish to go hula hoop after eating and have a brown sugar meal. Jumonji promises to pass the request along to the cook.
Not long afterward, they arrive and head to the observatory. Jumonji shows Ron and Toto around and explains that there is a model gun in the lobby to repel evil spirits. When they go to the observation dome, they hear the cook Minami Unno screaming that she will kill someone; she does this regularly to relieve stress because the closed-off dome is perfectly soundproof.
Then, the other guests join them in the dome: Eisaku Donzawa, Kayoko Onodera, and John Grizzly. Ron immediately recognizes Grizzly and wonders why a BLUE instructor is acting as a bodyguard at a party. Grizzly educates him about the Nandan Observatory Murder Case: Ten years ago, a viewing party for the same meteor shower they will be watching today was held. The party ended with the director at that time, Jumonji's father, and six guests shot in the dome. Neither the murder weapon nor the culprit was ever found. Jumonji adds that he is holding a "re-do" party to "overcome" that tragedy. While everyone cheers for him, the last guest, Princess Ori, arrives, and Ron flips the lever to open the dome. Everyone then watches the dome open and the telescope turn.
At night, everyone gathers on the roof for the meteor viewing and the standing buffet party, though Ron finds himself a chair. He also converses with Onodera and Donzawa about astronomy, stunning them and Totomaru with his knowledge.[112] After dinner, Ron hula hoops before he excuses himself and goes to bed early, without seeing the meteor shower.[113]
Hours later, Ron is found in the observation dome with a gun beside him and Onodera's corpse on the other side of the room.[114] After Princess Ori's scream wakes him up, Ron testifies that he does not remember anything after going to bed. Because the other guests cannot be ruled out as suspects, Grizzly and Toto begin investigating.[115]
After they inspect the room, Grizzly concludes that only Ron could have murdered Onodera as it was a perfect locked room situation. Surprised, Ron sits up because he did not know that the door had been locked; in the process, he discovers the missing master key in his pocket. Grizzly, subsequently, orders Toto to arrest Ron, though he should bring him his boots first; otherwise, Ron might cut himself on the glass shards covering the ground.
Toto brings Ron to a storage room and handcuffs him to a pipe. He asks him if he really cannot remember anything, and Ron affirms. Toto then shifts the conversation to the Bloody Field Trip Case and asks Ron if the situation now feels like the situation then. Ron replies that it does, and when Ron gives up, believing that he must have killed Onodera, Toto protests. He reminds him that he could not have killed her; after all, he only pressures murderers to death, and Onodera was an innocent person. His words slightly unfreeze Ron's brain, and he remembers that he is, actually, a terrible shot. He could not have possibly shot Onodera through the heart from behind. Wanting to find the real culprit, Totomaru hurries out.
After Toto leaves to investigate further, Ron realizes that, unlike five years ago, he is perfectly calm because, unlike then, he now has Toto by his side.[116]
Totomaru manages to prove Ron's innocence to Grizzly, and Ron is set free. However, because Toto does not understand how exactly he did that, Ron explains it to him: Onodera was killed at 1 a.m., but all seven lights in the dome were shot out before 11 p.m.; the telescope recordings proved this. Thus, at the time of Onodera's murder, the floor was already covered in glass shards. As Ron's feet were not cut when he was found, he could not have taken a single step after 11 p.m., and Ron could impossibly have shot Onodera with the telescope between them.
Ron adds that someone must have laced his brown sugar meal with sleeping medicine to ensure that he would retire to bed early. Everyone could have done this though, and not just Unno.[117]
Back in their room, Ron drinks multiple syrup packs to bring his brain back to full functionality, and Totomaru informs him that Grizzly promised to reopen the Bloody Field Trip Case investigation. A moment later, they hear a gunshot and see Grizzly falling past their window. They hurry outside but can only confirm his death.[118]
Ron inspects Grizzly's body and retrieves the fishing line he is clutching right before Jumonji and Donzawa, who carries an umbrella, join them; they heard the gunshot and wanted to find out what happened. Ron rapidly explains everything to them. Shortly afterward, Toto gathers everyone in the lobby for a general breakdown of the events: Grizzly was shot with the same gun as Onodera, meaning that the killer must have taken it from him.
Furthermore, because none of the guests have an alibi (they were either alone or asleep), they are all suspects. Ron and Toto then return to the observation dome for further inspection. They examine the door and discover glue on its sides; they also realize that Onodera is lying right in front of the dome switch. Because the dome opened right before Toto and the others heard the gunshot, Onodera might have flipped the switch prior to her death. After learning all that, Ron solves the locked room mystery but still does not know who the culprit is.
At this moment, Princess Ori approaches them to inquire if they know where the flashlights are. She asked Unno already, but Unno told her to get them herself, annoyed to be requested to fetch the flashlights a third time. This piece of information is the final puzzle piece that Ron needs to solve the case completely, and he thanks Princess Ori for giving him it.[119]
Ron and Toto call everyone to the observation dome. Totomaru reveals that Jumonji is the culprit: Jumonji immediately found Grizzly's corpse, although he could not have known its location if he had only heard a gunshot. He also ran outside without an umbrella to cover up that he had already got wet earlier when he killed Grizzly. Furthermore, Jumonji had left the party early. During that time, he attacked Onodera, put her to sleep, and brought her to the dome with Ron. He slipped the master key into Ron's pocket and placed the model gun next to him before he connected the telescope and the trigger of a gun he hid inside the vent with a fishing line. Lastly, he sealed the door with glue.
Because Onodera only received a light dose of sleeping medicine, she woke up earlier than Ron. She tried to turn on the lights first, in vain, because they were destroyed beforehand. Onodera then went to open the door. When it did not budge because of the glue, she turned the key, but that only locked the door. Ultimately, she flipped the dome switch, and when the dome opened and the telescope turned, the gun's trigger was pulled and she was shot in the back. Jumonji later retrieved the gun from the vent and killed Grizzly with it.
Jumonji exposed himself when he told Unno to get the flashlights before they entered the observation dome. He would only know that they would need them if he had destroyed the lights. Jumonji confesses to having killed Onodera because she was actually a journalist who wanted to reveal the truth behind the Nandan Observatory Murder Case: Jumonji's father killed the guests before committing suicide. Jumonji then hid the murder weapon to cover up his family's shame.
Hearing his confession, Kill on Sight activates, and Ron orders Jumonji to shoot himself. Toto stops Ron before the ability takes hold of Jumonji, but Jumonji swallows a cyanide capsule. With his dying breath, he tells Ron that he will never escape "his" grasp.
While everyone goes to the lobby and Totomaru calls the police, Ron stays behind and opens the dome,[120] and the "96"-mark under Onodera's corpse becomes visible in the sunlight, indicating that this case purposefully felt like the Bloody Field Trip Case and that both cases were orchestrated by the same people.
Ron retracts his words about giving up on detective work and declares that he will never forgive whoever did all this to him;[121] at the same time, he is excited to have his personal mystery now. He asks Toto if he will continue to help him, and Toto affirms.[122]
Poisoned Latté Case
Toto visits Ron and helps him with his gigantic futon. Afterward, they discuss the events of the Island Observatory Murder Case and the fact that the boat which carried the corpses of Grizzly, Onodera, and Jumonji sank and the entire crew went missing. Whoever gave Ron his "96"-scar must have been responsible for this as well.[123]
Later, Ron works a shift at Pot Coffee; he has been doing shifts there ever since he taught the shop's owner how to make his special brown sugar latté. At some point, Totomaru and Chicory Monki enter the shop, and shortly afterward, Hayami, Julie, and Tamada arrive. Ron quickly prepares everyone's drinks; he decorates the lattés with platypuses and gets offended when Hayami calls them ducks while picking up her order.
When Ron learns that Chicory is a crime reporter, he tries to get into her good graces; after all, Chicory could be a valuable source of information for difficult cases. However, Ron's attempts only annoy Chicory, particularly because they seem to bother Totomaru. A moment later, Julie dies after drinking a poisoned latté.
The ambulance and police arrive, and Ron is about to inspect the corpse when Chicory interrupts him. She urges him to leave and make room for Toto, "the famous detective" who will definitely solve the case[124] while she records everything.
Toto then interviews the suspects, among them Ron as he has prepared the drinks. Hayami brought the lattés to their table, and right after she and her friends took a group photo with the drinks, she excused herself, having received a call. Julie left the table too to take more photos; during that time, Tamada was the one watching the drinks. When they all came together again, Julie picked the first cup and then collapsed after drinking it. Ron points out that, considering the chain of events, he, Hayami, and Tamada all had an equal opportunity to poison Julie. Totomaru objects because Ron could not have possibly known which latté Julie would choose; he also has no motive for indiscriminate murder. Ron praises Toto's improved deduction skills, and Tamada informs them that Julie took the latté that was the farthest away from her.
Ron, Toto, and Chicory then check Julie's social media posts and the pictures Chicory took earlier. They find a picture of the three lattés right after Ron finished them and the group picture in which Julie poses with her latté. Thereafter, Ron offers Toto a jumbo-sized hot towel with the Pot Coffee logo on it, saying that it might be a hit on social media. Toto replies that it might stand out for the wrong reasons; Ron tells him this is the key before he pushes his hair to the side, indicating that he solved the case.
After Ron lets Toto in on the mystery, Toto calls everyone together: Hayami killed Julie. She poisoned one latté and scratched the platypus art on the other two, knowing that Julie would choose the poisoned one as it was the best-looking one. "Toto" figured this out after comparing Chicory's photo to the group picture.
Hayami admits her crime; she killed Julie because she always wanted to be the center of attention and stole Hayami's boyfriend when he got scouted by a talent agency. Ron then pressures Hayami to smash her head on a teapot sculpture, though Toto can save her on time.
Afterward, Ron makes Chicory and Toto more lattés on which he writes "You did it!!", "Got 'em!!", and "Reporter Connections." Toto stirs them before showing them to Chicory.[125]
Sandbox Murder at Dawn Case
At 6 a.m., Toto comes to the Maison du Kamonohashi to tell Ron that he does not have any cases for him. This immensely disappoints Ron as he is so bored that he even tried engaging the dead ants in conversation. Still, he thanks Totomaru for his hard work, as he can see that he must have done paperwork all night. Totomaru confirms this and adds that he worked so hard that he hallucinated when he walked past a park at dawn: A "strange blue thing" hovered in the air for a moment before disappearing.
Intrigued by this "hallucination," Ron drags Toto to the park. There, they discover a tomb in the sandbox, and when Toto digs there, he finds the corpse of Tatsuo Kinoshita. They call the police, and the body is examined: Kinoshita died of suffocation at 3 a.m.
Just past 7 a.m., Kinoshita's friends Tetsu Yamada and Hajime Satou arrive and are questioned. According to the writing in the sandbox ("I was killed by Tetsu Yamada"), Yamada is Kinoshita's murderer; his shoes are even full of dirt and sand. However, Yamada has an alibi: He was at home from midnight onward, watching a movie with friends who can attest his claim. He only came out now to take out the trash.
Ron then chats with ants and gets upset over an antlion trap, frustrating Totomaru because he believes Ron is only playing around. Ron has already solved the case though and entrusts him with his deductions.
Thereafter, Totomaru and Ron gather Yamada, Satou, and the other police officers so that Totomaru can present Ron's deduction: Yamada killed Kinoshita. He drugged Kinoshita before midnight and brought him to the park where he buried him in the sandbox, but left the space around his head free of sand. Yamada ran a hose through the sand to provide him with air and covered Kinoshita's head with a sheet. In its middle was a hole, and Yamada put sand on top of the sheet, turning it into an antlion trap: The sand slowly fell through the hole and onto Kinoshita's head. The sand gradually covered his head, and Kinoshita died of asphyxiation hours later. Yamada also tied a string to the sheet to pull it away while he was still at home. Having created a "perfect" alibi, Yamada dared to write "I was killed by Tetsu Yamada" into the sand to ensure that he would get questioned early before his testimony fell apart.
Yamada confesses that he killed Kinoshita because he flirted with his girlfriend Mika. His words trigger Ron's Kill on Sight ability, and Ron persuades Yamada to stab himself with a broken bottle, but Toto can stop him. Yamada is arrested, subsequently.[126]
Mad Chameleon Murder Case
Ron sees Mofu at the East Japan Integrated Hospital to find out more about his Kill on Sight ability. She tells him that it is not a hereditary trait[127] and writes him a referral letter to the Aichi Research Center to get a full examination.[128]
Later, Ron accompanies Totomaru to Nagoya; Totomaru was sent there by Amamiya to check up on Kawasemi who is currently in a slump. Though Ron claims he is only coming too because, if Kawasemi was unable to solve any cases lately, there would be more for him, Totomaru is sure that he is actually concerned for Kawasemi. Ron says he considered this too, but he never cared about someone else's feelings, at least in his student days. He does, however, acknowledge Toto as his friend.
In Nagoya, Toto heads to the police headquarters alone. Ron eventually texts him that something came up and that he will join him and Kawasemi later.[129] He then heads to the Aichi Research Center to get examined.[128] Afterward, Ron calls Toto who tells him that he and Kawasemi witnessed a murder and gives him the details on the Mad Chameleon Murder Case. Ron is certain that the culprit is not using a disguise. He adds that he will go to them and that they should wait for him.[130]
As soon as Ron arrives, the police arrest him, considering him a "suspicious person." Only when Kawasemi informs them that Ron is a crime consultant, he is set free. Ron asks why the victim, a student, was wearing a suit. Kawasemi tells him that he must have been at a job interview and that all of the Mad Chameleon's victims had been wearing suits.
Ron remarks that they must be hiding something; after all, nobody can fully change their appearance. Kawasemi immediately understands what he means: The "It's Me!" scam in which fraudsters dress in suits and impersonate bank workers to gain the trust of their targets. All victims are receivers in the scam and they lied to hide their connection to the fraud ring as the Mad Chameleon is part of it as well. The victims' phones were stolen to get rid of any evidence of their contact with the fraud ring.
With the mystery solved, they only need to identify and catch the culprit. Ron insists that only Kawasemi can do it; when Kawasemi persists that he cannot, Ron vexes him until he breaks Kawasemi out of his slump. He then makes him think about the suspects, and Kawasemi immediately "sees" the answer: The culprit did not elbow anyone; he checked his watch because of the sign announcing the time of the road closure. He thought he still had time because he was wearing a watch that showed the incorrect time. Because of that, he had to hide in the shop.
As the Mad Chameleon gave the police the wrong contact information, they need to wait for him to return for the stolen smartphone that he had hidden in the shop. Ron points out that the phone is right in front of them and is "making a call."[131]
Later, while Ron and Toto are on their way home, Kawasemi catches the Mad Chameleon and calls Toto to inform them about his success. The culprit's watch was off because he partied in Singapore until yesterday. Then, Toto asks Ron about his "urgent matter" from earlier, and Ron tells him that he was examined for his "pathological culprit killing" and that, according to his test results, the doctors might be able to lessen the symptoms.[132]
Yadagami-sama Murders Case
Ron calls Toto to ask for his opinion as he is unsure whether to help Spitz find his missing brother. Toto tells him that they should help him; after all, Spitz has been assisting them with their investigation. Ron then informs Toto that Spitz has been tailing him.[133]
Toto and Spitz head to Ron's now partially furnished apartment. Ron reveals that he only wants to help Spitz if he steals BLUE's file on the Bloody Field Trip Case which angers Toto, and he scolds him for pressuring Spitz into committing a crime. They should help Spitz without demanding anything simply because he is their friend. Toto's words move Spitz, and he accepts Ron's condition. Immediately afterward, they travel to Yada Village in the Yamanashi Prefecture.
On the way, Spitz imparts that his brother was an anthropologist; he vanished eleven years ago when he took Spitz to Yada Village for research. They also discover a waterfall and spot a a woman standing by a shrine. A moment later, a villager throws an axe and nearly hits Toto. After the man apologizes, Ron, Toto, and Spitz continue their journey.
At Yada Village, the mayor and various villagers protest against a surveyor who wants to evict the entire village to build a dam. The villagers claim that this will anger Yadagami-sama, the god protecting their village. After the surveyor leaves, the mayor invites Ron, Totomaru, and Spitz to stay at his house. He guides them there, and when they arrive, they meet the woman from the waterfall who turns out to be the mayor's granddaughter Mii. Ron quietly notes that Mii was oddly surprised to see Spitz.
Later, Ron, Spitz, and Toto have dinner in their room. Spitz gives them more information on his brother's disappearance: After questioning the villagers all day about the Yadagami Legend, he and his brother went to bed. The next morning, his brother was gone, and although everyone, including the police, thoroughly searched the village, Shepherd Feier could not be located.
At some point, Toto looks out of the window and sees a gigantic snake wrapped around the surveyor who is staying in the mayor's hut on the other side of the river. Immediately, Ron, Spitz, and Toto hurry to the hut where they only hear a bang and find neither a snake nor the surveyor inside. The following morning, the surveyor is discovered strangled in the waterfall basin outside Yada Village.[134]
After the local police arrive, they, Ron, Toto, and Spitz inspect the crime scene. The surveyor, apparently, did not die from strangulation; he died when he hit his head falling into the basin. Then, the mayor and Mii come, and the mayor claims that Yadagami-sama killed the surveyor. Ron asks Mii what she was doing by the waterfall yesterday, and Mii explains that she was making an offering to Yadagami-sama.
Thereafter, Ron, Spitz, and Totomaru walk to the hut and meet Muroi on the way. He tells them that Yadagami-sama is a living legend; there are still reports about its "power of disappearance." For example, the god made machinery vanish 15 years ago, and Shepherd Feier disappeared as well. Muroi also reports that he once fell asleep in the mountains, only to wake up at its foot. When Ron asks about his whereabouts yesterday, he testifies that he was at the Yadagami Shrine to see the objects there, but it was closed.
When they arrive at the hut, the police officer tells Ron, Toto, and Spitz that they have found nothing suspicious except for a bottle of brown sugar which Ron recognizes as the one he lost yesterday. Disheartened, Spitz goes to the window—and spots a white snake in the river. However, when Ron and Toto look outside, they see nothing. Considering the "snake" Spitz saw and the fact that the stain the brown sugar bottle left is not where the bottle currently is, Ron solves the case.[135]
They then gather everyone by the waterfall, and Totomaru explains what happened: The mayor strangled the surveyor with a rope from the shrine and threw him into the basin. He placed a picture of a snake curled around a man in the hut and attached it to a tatami mat. It was held up upright with a string; one end was tied to a rock that was dangled out of the window, the other pinched in the front door's frame. When Ron, Toto, and Spitz arrived and opened the door, the mat fell, made a "bam" sound, and Yadagami-sama "vanished." The rock and the string tumbled into the river, and Spitz later assumed the string was a snake.
The picture is a scroll from the shrine; to hide its absence, the shrine was closed yesterday. And the location of the brown sugar bottle and its stain did not match because the mayor lifted the mat to retrieve the scroll. Because this trick required witnesses to work, only the mayor could be the culprit: After all, he assigned Ron, Spitz, and Toto to that specific room.
As soon as the mayor confesses, Ron pressures him to fall into his death. However, when Toto tries to save the mayor, the ground gives up under them. Toto can hold onto a rock, and Ron, Mii, and Spitz pull him and the mayor up with a rope a mysterious person tossed them.
Following the mayor's arrest, Ron and the others return to the mayor's house. There, they encounter Shepherd Feier who has been hiding at Yada Village all along after becoming the target of a "certain" organization. Now, because the mayor killed the surveyor to protect him, Shepherd Feier does not want to hide anymore, as he cannot live at the expense of others' happiness. He, thus, asks Toto to arrest him. Ron then informs Shepherd Feier about Mii's feelings for him before he and Toto leave them and Spitz alone.[136]
As promised, Spitz travels to BLUE to steal the Bloody Field Trip Case file. However, when he returns, he does not have the file with him but a message from Aimee Emmerich: The lead Ron is searching for has been deleted from both the police's and BLUE's records; it concerned a bit of blood that belonged neither to Ron nor to any of the victims. And since Aimee learned about the Island Observatory Murder Case, she is sure that the Bloody Field Trip was orchestrated by the M. Family; they also gave Ron his Kill on Sight ability alongside his "96"-scar. Aimee adds that while she wants to help Ron, she cannot because there is an M. Family spy at BLUE.
After finishing Aimee's message, Ron declares that he will best the M. Family.[137]
Shibuya Revelation Serial Murders Case
Pretending that he has to deliver candy to Toto, Ron manages to get access to a crime scene at Shibuya Mall Park. There, Ron offers Amamiya a subscription to Kamonohashi Sweets before they arrive by the body: The blindfolded, bound victim has been impaled by the horn of a unicorn statue. A plate saying "And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them" hangs from his neck. Amamiya wonders if it is some kind of poem, and Ron informs her that it is a verse from the Revelation of St. John.[138]
While Amamiya and Toto speak to an officer, Ron inspects the corpse and quickly solves the case. He passes his deduction to Toto so that he can present it to Amamiya: The culprit suspended the victim from the arch above the unicorn, and the victim had to hold onto the rope so that he would not fall into the horn. When his strength eventually left him, he let go of the rope and was impaled.
The victim is then identified: His name is Ryouji Katsunami and he belongs to a hacking group that recently committed a cryptocurrency theft. When Ron learns that the police discovered a burn mark on Katsunami's neck, Ron hurries to the corpse to check the spot. The mark reads "0 10:00." Ron tells Toto that the M. Family must be behind the murder and that this is a direct challenge to him: The burn mark is in the exact same location as his "96"-scar, and the Revelation quote is from Chapter 9, Verse 6.[139] Furthermore, the numbers are announcing the next murder: Someone is hunting down all three members of the hacking group. "10:00" indicates that the next murder will happen at 10 a.m.—which is in thirty minutes.
Ron and Toto split up from Amamiya to find out what the "0" could mean and run into Chicory. Toto asks her if she knows a place nearby that has something to do with "0," and Chicory tells him about Platform 0 at the Shibuya Station Bus Terminal. Unconvinced that this is the solution, Ron does not accompany Chicory and Toto to the bus terminal; after all, the corners of the "0" are unconnected.
When Ron passes a food shop and hears a customer complain that there is too much sauce on his chicken and he cannot void touching it, Ron figures out what the "0" means: It refers to the scramble crossing; the missing corners stand for the areas where there is no pedestrian crossing paint. Ron phones Toto to meet him there.
Ron as well as Chicory and Toto make it just in time, and exactly at 10 a.m., the crossing is covered in smoke. When the smoke subsides, it reveals Hibino's corpse. He was pierced with through his heart with an arrowing bearing the mark "Δ 11:00."
The third hacker is also at the scramble crossing and when he sees Hibino's corpse, he runs away. Toto runs after him while Ron remains with the corpse.[140][141]
After Spitz catches the third hacker, Ron joins him and Toto. The hacker tells them that he and the others were hired by someone called "Marry Ito." That person masterminded the cryptocurrency theft and is now killing the hackers he employed. "Marry Ito" then calls the hacker: If he wants to live, he has to bring the cold wallet with the stolen cryptocurrency to the Delta Hotel at 11 a.m. If he calls the police, their deal will end and he will die.
Hearing this, Ron concludes that the message on the arrow means the same: the Delta Hotel at 11 a.m. He persuades Toto to use the third hacker as bait to catch "Marry Ito," and Toto calls Amamiya to inform her about the plan. Afterward, Ron and the others head to the Delta Hotel where they meet Amamiya who has gathered and stationed officers around the hotel.
Ron stays in the lobby and keeps a close eye on everything, and Toto and the third hacker hide in a hotel room. At 11 a.m., the third hacker unexpectedly runs into the lobby, and Ron notices that the chandelier will fall just when the hacker passes under it. He points this out to Totomaru who manages to tackle the hacker on time. The chandelier, thus, falls without injuring anyone.
A moment later, music starts to play. Ron immediately recognizes it as Haydn's 96th Symphony and realizes that they have played right into the M. Family's hands:[142] Haydn's 96th is also known as the "Miracle Symphony" because, during its first performance, a chandelier fell but did not hurt anybody—just like earlier.
Afterward, Amamiya tells Ron and Toto that the tip of the arrow that killed Hibino is made of iridium and then takes the third hacker to the Metropolitan Police Department. Spitz goes to check out the crossing again.
Meanwhile, Ron shows Toto that he found a tablet with the next announcement—"Ⓗ 12:00"—behind the hotel's music player and informs him that iridium is in group nine, period six of the periodic table. This, Haydn's 96th, and the Revelation quote from Chapter 9, Verse 6 indicate that all the crimes are connected to his "96"-scar. Ron is sure that, with the third hacker's safety guaranteed, the M. Family will now settle things with him. He and Toto then hurry to Shibuya City View Tower, the only place nearby with a heliport.
They go up to the heliport where they encounter the third hacker. He tells them that the police car was attacked, and he was brought to the tower by someone wearing a helmet. That man ordered him to give Ron and Toto a phone. As soon as the hacker hands it to them, "Marry Ito" calls: He says that Ron will taste "a detective's despair" at noon.
While Ron has no idea what "Marry Ito" could mean, he suddenly solves Hibino's murder: Hibino was not shot from afar; instead, he was stabbed at close-range with the arrow, and the culprit used e.g. a whip to make a "whooshing" sound. The culprit, therefore, must have been at the crossing. Ron then tears off the third hacker's face, exposing Winter Moriarty. He reveals that he has been suspicious of the hacker since "Marry Ito's" first call as it was oddly one-sided and the only reason they knew to go to the Delta Hotel. Until he figured out the scramble-crossing mystery, Ron also considered that the third hacker might be the culprit's assistant, not necessarily the culprit in disguise.
Shortly afterward, Ron checks the phone Winter gave him and sees that it is already noon. The screen on the opposite building then explodes, and Ron can only watch the scene in horror while Winter tells him that he cannot save anyone,[143] particularly the third hacker and Amamiya as Winter strapped bombs around them that were set to explode at noon. Ron and Toto try to call Amamiya and realize that their phones are broken; they were destroyed by a magnet when they entered the tower.
Winter keeps taunting Ron, and Ron insults them and the M. Family's methods in return. Although Winter longs to kill Ron, they decide against it as they are a Moriarty and, thus, had to engage Ron in "a battle of wits" and give him "a detective's despair." Hearing this phrase yet again, Ron realizes that Amamiya and the hacker are still alive: "A detective's despair" means being unable to solve a problem you could have solved, or being unable to save someone's life. This means that the problem can be solved; the explosion was, therefore, only a dummy and did not kill Amamiya and the hacker.
Frantically, Ron tries to figure out how to solve the problem, but cannot think of something. Only when Toto points out there was already an explosion at twelve, does Ron realize that it is not twelve yet: The explosion destroyed the opposite building's clock screen, and they can only rely on the phone Winter gave them—and it shows the wrong time. Winter reveals that it is, in fact, 11:55:42.
Ron tells Toto to search for anything related to "96," and Toto immediately looks at Ron's scar: Ron is the only thing related to "96" around. Thus, Amamiya and the hacker must be in the tower. Winter discloses that they are in the first-floor storage room. With only two minutes left, Totomaru tries to call the elevators, but they are both on the first floor. Winter is certain of their victory; however, when it turns twelve there is no explosion: Spitz listened to their conversation and could get to the storage room on time.[144]
Ron demands to know what the meaning of his "96"-scar is. Although Winter refuses to tell, their wording makes Ron work out that the "6" must stand for the "sixth Holmes generation." Irked, Winter deliberately triggers Ron's Kill on Sight ability by confessing to the Shibuya Revelation Serial Murders Case. Ron attempts to persuade them to jump off the roof; surprisingly, Winter is able to resist him though. They blow up the glass railing behind them and is about to flee when they receive a call from their brother and is shot down the roof.[145]
Later, Ron, Spitz, and Toto gather at the Maison du Kamonohashi. Totomaru informs them that Winter's corpse was exchanged with another, and Spitz says that he intercepted the final transmission and heard that someone called them "Winter." Ron muses if "Winter" is a codename and guesses that whoever called him, the one they called "brother," is the M. Family's leader. Ron becomes even more determined to take him down.[146]
Midsummer Beach Hut Drowning Case
After Mofu was kicked out of her condo, Ron suggests she moves into the Maison du Kamonohashi. On the day of her move, she runs into Toto, and they visit Ron together. Mofu reveals that she has found a way to suppress Kill on Sight, but it requires Ron to take a dangerous combination of various medicines; thus, Mofu only permits Ron to take it when she is around.
Mofu then receives a call from Shikada who reminds her that she has a surgery today. After she leaves, Totomaru suggests that Ron takes a break from solving cases. They decide to go to the beach and on their way out, they run into Mofu whose surgery was cancelled last-minute. Ron invites her to come along, and they all head to Natsukaze Beach.
There, they seek out the beach hut because Ron wants to buy shaved ice, though, to his misery, they sold out of shaved ice this morning. This sours Ron's mood, and he does not feel like swimming anymore. When Mofu offers to do the activity on his to-do list, Ron lends her his platypus swim accessories. Mofu goes swimming while Toto remains behind with Ron.
They then overhear an argument between the beach hut owner and two surfers, and Ron drags Totomaru to the surfers when the argument is over. He tells them that Totomaru is a police officer and that he might help. The surfers impart that their friend Taku Manba got a stomachache after eating something from the beach hut yesterday. Last night, he went to confront the owner but never returned. Totomaru advises them to contact the local police, and a moment later, Ron notices Mofu waving to them: She has discovered a corpse by the rocks; the surfers immediately identify it as Manba, and Ron deduces that he was murdered.[147]
After the local police arrive, Toto explains to an officer the situation, and Mofu informs him about the result of her autopsy: Manba went to speak to the beach hut owner at 10 p.m. after he got drunk with his friends and he drowned between 2 and 3 a.m. His hands are purplish red, but he is otherwise uninjured. The officer concludes that he must have tried to surf while drunk and subsequently drowned, but Ron objects: Not only is Manba wearing a dry suit for boaters or divers, but the suit is also too large for him, and his surfboard is still where he left it the day before.
Thereafter, Ron, Mofu, and Toto question the beach hut owner about what he did last night: He cleaned up the shop, went home, and then drank all night with friends. Although he acts highly suspiciously, they cannot simply arrest the owner. They then buy food from him and head to their beach chairs to eat and discuss the case.
Because Totomaru's yakisoba is burned and barely edible, Mofu goes to get it replaced but trips on the way and swallows a bit of salt. She notes that it is unusually salty, and after Ron tastes the sand as well, he solves the case.[148]
Ron takes his Kill on Sight medication[149] before he, Toto, and Mofu gather everyone. Toto then reveals what happened: The beach hut owner killed Manba. Manba passed out in front of his hut, and the owner dressed him in a dry suit and placed him on a raft which he had created by combining ice blocks with salt. For that reason, the sand is especially salty, and he has run out of ice despite there being barely anyone at the beach.
The dry suit would ensure that Manba would not get chilblains or marks from the rope that tied him to the raft. The beach hut owner then pushed Manba on the raft into the ocean. Manba woke up when the ice melted, and drowned when it was fully gone. Because he had clung to the raft, he got chilblains on his hands. Furthermore, the hut owner's fingerprints were found on the surfboards outside the inn where Manba and his friends were staying; he left them there when he tried to take Manba's. He murdered Manba because he had already received three complaints of food poisoning; if Manba had reported him too, the health bureau would have closed his shop.
The beach hut owner confesses, and because of the medicine, Ron does not compel him to commit suicide. Mofu and Toto are happy that it worked, but the joy is short-lived: Ron suddenly calls Toto and Mofu "Max" and "Molly" before he passes out.
The next day, Totomaru visits Ron, and Ron tells him that Max and Molly were his childhood friends. Totomaru informs him that the medication's side effects include losing one's consciousness and experiencing memories of the past. He also requested that she allows Ron to take the medicine in Toto's presence as well, and Mofu gave her permission.[150]
Genius Composer Kidnapping Case
Three days later, Ron accompanies Totomaru to a Nyo-Nyon concert. On the way to the venue, they talk about the talent kidnapper Hummingbird because he recently kidnapped the sculptor Masatatsu Oyama: Hummingbird always sends calling cards to his targets, and although the police put great effort into protecting the targets, Hummingbird is always able to outmaneuver them. Curiously, Hummingbird never asks for ransom; he simply wants his abductees to demonstrate their talent to him.
When they arrive at the venue, Ron spots a man with a mask and sunglasses who simultaneously watches two videos—one about first-class ballet, the other about a master craftsman—on two different smartphones and has two different earpieces in each ear. Ron asks the man if he can guess his occupation, and when the man allows it, Ron deduces that he is Hummingbird—or, rather, a wealthy heir who admires him. Totomaru apologizes for Ron's behavior and ushers him inside.
Following the concert, Toto's friend Higuchi, who works at the venue and got them their tickets, asks for Toto and Ron's assistance: Hummingbird sent a calling card to Nyo-Nyon. While he and Toto take a look at the card, Ron catches Nyo-Nyon's attention with his deductions.[151]
On the day of the announced kidnapping, Nyo-Nyon calls Ron because she wants him to protect her alongside the Metropolitan Police Department's Special Crimes Division under Namazu and Toto, who was requested because he was the officer at the concert venue. Namazu is suspicious of Ron, but before he can check his ID, the Yamanashi Prefecture Police under Sannou arrives as the mansion is on the border of Tokyo and Yamanashi[152] and they also received a calling card from Hummingbird. Begrudgingly, Namazu agrees to cooperate with the Yamanashi Police.
Inside the mansion, Nyo-Nyon tells them about the building's history: A fire destroyed the original building, sans the clock tower. For that reason, she has installed smoke detectors all over the mansion. Sannou then suggests keeping Nyo-Nyon in a place where nobody could reach her, and Nyo-Nyon takes everyone to her composition room on the top of the clock tower. Namazu agrees to let her stay there.
Mitsubashi, Nyo-Nyon's manager, locks the staircase door, and everyone heads to wait in the living room. An hour later, the smoke alarm is set off, announcing a fire in the living room although there is none. Immediately, everyone hurries to the composition room, but Nyo-Nyon has already vanished.[153]
Namazu goes to contact his subordinates at the base of the hill while Mitsubashi shows Ron, Toto, and Sannou around the lower rooms. In the storage room, Mitsubashi notices that the curtain is gone, and Ron and Toto ask her a few questions regarding Nyo-Nyon's work. Although she claims not to know anything about music, Mitsubashi's word choices indicate that she is actually knowledgeable in this area. Ron notes this—and so does Sannou.
Afterward, they return to the living room, and Sannou announces that he has solved the case. However, he only wants to tell his deduction when Namazu returns. While they wait, Toto informs Ron that none of Hummingbird's victims filed criminal reports after their abductions. Ron then asks Toto to contact Chicory as he wants her to look into something for him.
When Namazu returns, Sannou says that he believes Mitsubashi to be Nyo-Nyon's kidnapper: Nyo-Nyon ran downstairs upon hearing the smoke detectors and pressed herself behind the locked staircase door, frozen in fear. Earlier, Mitsubashi took longer than the rest to arrive in the composition room. While the others hurried upstairs and did not notice Nyo-Nyon, Mitsubashi kidnapped Nyo-Nyon and hid her in a secret room.
Sannou now wants to take Mitsubashi to the Yamanashi Prefectural Police for further interrogation, but Ron and Toto object, saying that she cannot be Hummingbird[154] because she is the real Nyo-Nyon: She betrayed herself with her word choice earlier (referring to "volume" as "level") and showed signs of distress when she was in the composition room with the windows uncovered ("Nyo-Nyon" said "she" was afraid of heights). Mitsubashi admits everything: The other woman is a singer her agency hired to her "face" when she threatened to quick if she had to reveal her own.
Right before Toto uncovered Mitsubashi's secret, Namazu went to the foot of the hill because a suspicious person was sighted there. Sannou decides to head there as well, and Ron, Toto, and Mitsubashi accompany him.
On the drive, Ron tells Sannou "Toto's" deduction: After the smoke alarm went off, "Nyo-Nyon" looked out of the window and saw a group of Yamanashi police officers holding the stretched-out curtain from the storage room. They urged her to jump, she complied, and the officers, being Hummingbird's accomplices, carried her away. Then, one of the false officers had to accuse Mitsubashi of being Hummingbird to drive away with her under the guise of bringing her to the police station—as Sannou tried earlier.
Sannou parks on the side of the road and admits that he is indeed Hummingbird. He kidnaps geniuses for his daughter so that they can talk. Because she is a musical genius, he raised her to be the next top pianist but his strictness and sheltering broke her. The talent of outstanding geniuses is the only thing that still stirs her soul.
Hummingbird then says that "Nyo-Nyon" is in the car's trunk, and while Ron and Totomaru check it, he escapes. Ron confesses that he knew this would happen and did not interfere because he is fascinated by the love he has for his daughter—and because the conversations the abducted geniuses have with Hummingbird's daughter make them happy and help them recover from slumps. He theorizes that the daughter can sympathize with the geniuses' loneliness and heal their wounds with her understanding.
Two months later, Ron and Toto learn that Mitsubashi founded her own agency and created more hit songs.[155]
Psychological Research Lab Murder Case
One day, Ron is playing with dinosaurs when Toto visits him. Toto misinterprets the situation and assumes that Ron has regressed out of boredom and advises him to see Mofu. Ron explains that he is recreating his memories because his recollections before the age of six are spotty, e.g., although he can clearly remember certain events like playing dinosaurs with Max and Molly, he cannot recall the fourth person who was with them. He thought he could remember by reenacting the memory, in vain.
Ron is indeed bored though, and because Toto has no case for him, they contact Chicory. They meet her the next day at Tokyo University as she has to gather data at a psychological research laboratory there.
Together, they head to the Maruyama Laboratory where they are welcomed by Takanori Aoe. He briefly explains what they do—researching the mechanisms of emotions and learning—, and Ron asks if he knows why his early childhood memories are missing pieces. Aoe replies that there are multiple possible causes, e.g. dissociative amnesia. Then, Aoe has to leave, and Kanae Himeno continues the tour.
After Himeno shows Ron, Chicory, and Totomaru the shield room, two members of the lab, Shun Oigawa and Renjiro Imai, get into a fight about using the experiment room in the afternoon. Riko Niki then asks Himeno why she does not "flirt" with Aoe so that he can solve the problem as she "always" does.
Later, when it is time for Ron, Totomaru, and Chicory to leave, Himeno apologizes for the earlier incident. Ron says he can understand as the competition at his former school was fierce as well. Whenever someone started a fight with him, he would end it by breaking the other person's nose. The anecdote lifts Himeno's mood and makes her swear to work hard to benefit humanity with her research like Aoe.
The next morning, when Ron and Toto are at Pot Coffee, Toto receives a call from Chicory: Himeno was killed in an explosion at the research lab.[156] Ron and Toto head to the university, and after Amamiya assigns the case to Toto, they start interviewing the lab members.
First, Ron and Totomaru speak to Aoe. He testifies that he performed an experiment with the MRI machine in the research wing last night. On the way out, he passed by the experiment room, but the light was out. Aoe adds that they lost a computer with ten years' worth of experiment data in the explosion and that they received a threat letter addressed to Himeno this morning; it was sent out yesterday.
Afterward, Ron and Toto interview Imai, Niki, and Oigawa, and they reveal that they all knew that Himeno would use the experiment room this morning: They used a randomizer to determine who would get the slot. Furthermore, not only has none of the students an alibi, but they also all dislike Himeno for various reasons. E.g. Himeno once scolded Niki for cancelling an MRI experiment. Because the MRI machine has a high maintenance cost, they have to keep the operation ratio high and are not permitted to cancel experiments.
Ron then instructs Totomaru to get the experiment room's use log and tells him that he wonders why the threat letter arrived after Himeno's death. After all, if its target is dead, a threat letter loses its meaning. Ron adds that it is curious that the culprit sent the letter before it was decided that Himeno would get the experiment room. He inquires about the use logs, and after Toto hands them to him and Ron reads through them, he solves the case.[157]
They gather the lab team as well as Chicory, who has arrived in the meantime, to reveal what actually happened: Aoe is the culprit. Because he wanted to destroy the computer in the research lab as it contained evidence that he forges the data for his papers, Aoe took the computer to the MRI machine whose magnetism erased the data. To divert attention from the computer, Aoe filled the shield room with flammable gas;[158] the next person that opens the door would then trigger an explosion. He also sent threat letters to each student to the university, and when he found out that Himeno was the one who was killed in the explosion, he picked out her letter and showed it to Ron and Toto.
Ron figured out that Aoe is the culprit because he did not use the experiment room all week, knowing that it would be futile. Aoe admits everything and says that he does not feel bad to have killed Himeno; after all, some sacrifices are required to create a "great man." He then tries to blow everyone up with a bomb, and Ron tackles him before he loses consciousness because of the side effects of his Kill on Sight medication.
Ron wakes up in his apartment the next evening. Totomaru, who has just returned from Himeno's funeral, is there too. Ron tells him that he dreamed of his childhood again and that he is sure that there is something important in his past he cannot remember.[159]
Plateau Auberge Serial Murders Case
Ron calls Totomaru to his apartment because he received a letter addressed to the manager of the Maison du Kamonohashi which would not be unusual if it had not been postmarked 17 years ago. Back then, Ron's maternal grandfather was the manager, but he has since passed away. Ron only became the manager five years ago when his mother gave him the position. She is currently travelling the world, whereas his father died of an illness before his birth.
Totomaru is unsure whether to accept the dinner invitation; after all, it is uncertain if the auberge is still in business. However, the envelope did not only contain the invitation and menu but also an emerald, and when Ron says they should return it at least, Toto relents. They leave immediately as the dinner is set for today.
On the way, Ron and Toto encounter Tiger Dan and Lenny Gardner who have also been invited to the dinner. Together, they head to the auberge where they are greeted by Shusuke Sakai, the chef and the facility's only employee. He hands out the keys and tells everyone that dinner will be served at 6 p.m. Ron and Toto then meet Mia Costa, another dinner guest, who also has an emerald; hers, however, was given to her by her late mother.
At 6 p.m., everyone enters the dining room and takes place around a round table. Among the guests are also Karen Lily, Bill Clark, and Tom Sasaoka; curiously, a teddy bear sits at the table as well.
One by one, Sakai brings out the four courses: an edible flower salad, lobster soup, fresh fish steamed with white wine and served with a foam garnish, and three kinds of roasted wild game. Dan, Lily, Sasaoka, Gardner, and Clark display discomfort at the sight of every course. Right before dessert, Clark excuses himself, and when Sakai brings out the chestnut mousse cake, the others pass on it as well. Gardner even stands up and says that he should not have come to the auberge after mumbling about wishing that he had not driven his truck on "that day."
The next morning, Ron and Toto hear Sakai, Dan, and Lily calling for Gardner in his room: Lily and Dan heard a weird rupturing sound from Gardner's room and wanted to check up on him, but he is unresponsive. Lily picks the lock, and they find Gardner dead in his room with an ice pick lodged in his chest and covered and surrounded by flowers.[160]
Hearing the commotion, the other guests arrive as well. Totomaru reveals that he is a police detective and asks Sakai to contact the local police and Clark to help him examine the corpse. Clark determines that Gardner died about three or four hours ago, and Ron notices that the surface of the ground right below the window is torn up and finds an emerald next to the corpse.
When Sakai returns and says that the landline does not work and that they have no phone reception, everyone goes to check the ropeway station, but it is out of service which means they are now stranded and isolated on the plateau. Sasaoka then runs away, and Ron and Toto hurry after him while the others return to the auberge.
They find Sasaoka in the woods. He explains that, 17 years ago, a man with a crescent moon birthmark invited him to a meal which consisted of the exact same courses as yesterday's dinner. He also hired him to drive a man and a pregnant woman to a hospital; Sasaoka later learned that the man's corpse was found in the Thames. Sasaoka is sure that he was invited to the dinner to be blackmailed because of his involvement in that apparent murder.
Sasaoka's story distresses Ron because his father had a crescent moon birthmark, and just after he tells Toto that, he suddenly recalls a memory of his father. A moment later, Lily screams because someone taped the menu on the bathroom door. Ron and Toto go into the bathroom and[161] find Sasaoka's corpse inside. He was stabbed in the chest with a knife around 9 a.m. after he struggled against his assailant, and food coloring was used to tint the water red. When Ron takes in the crime scene, he figures out why Sasaoka's and Gardner's bodies were so oddly arranged.
Later, everyone gathers in the dining room, and Toto asks for everyone's whereabouts around 9 a.m. As nobody has an alibi, they are all suspects. Karen protests, saying that they are not even connected together. Ron questions this, and Toto reveals that Gardner's and Sasaoka's murders were modelled after dishes from yesterday's dinner: Gardner was covered in flowers (the edible flower salad), and Sasaoka was placed in red-colored water (the lobster soup). However, while Mia and Sakai do not know the meaning behind the dishes, Sasaoka and Gardner knew it—and so do Clark, Lily, and Dan.
Ron persuades them to confess, and the three admit that they, too, were hired by the man with the crescent moon mark 17 years ago; Gardner and Mia's mother were involved as well. Ron is shocked when he learns that everyone is connected to the Jim Gore Murder Case because the M. Family was behind it.[162]
Afterward, Totomaru, Ron, Lily, and Mia decide to look through the locked rooms; Clark and Dan decide to rest instead. When they find nobody, Lily and Mia retreat to their rooms. Ron and Toto, however, keep wandering through the auberge, and Ron admits that he suspects his father to be the crescent moon man because he recalled a childhood memory featuring him.
They then stumble over a storage room where they discover an emerald, a framed picture of Ron's father, and a recorder. The recorder plays a voice recording of Ron receiving a lockpicking lesson from his father—Eliot Moriarty. This unlocks Ron's memories, and he remembers that his father taught him all about crime until he was six. Remembering that he is a Moriarty frustrates and confuses Ron.
A moment later, Sakai arrives to tell Ron and Totomaru that he found Clark's corpse in the wine cellar, covered in extinguishing foam. Because Ron is currently preoccupied with his inner conflict, he cannot investigate, and Toto steps up.[163]
Clark was strangulated, unlike Sasaoka and Gardner, and his body is still warm; and the crime scene is yet another reference to one of yesterday's dishes (fish steamed with white wine and foam garnish). After Toto finishes his examination, he asks what everyone was doing; again, none of the guests has an alibi.
Totomaru then checks the menu, and because "three varieties of roast game" is next on the list, Dan theorizes that three people might die at once next. The guests become nervous about this possibility, and Toto tells them to calm down and wait in the dining room while he and Ron investigate.
Ron is still spaced out when he follows Totomaru through the auberge; he only recovers when Toto says he thought Ron's ancestors were detectives. Ron clarifies that his mother is from the Holmes family while his father is from the M. Family. He also declares that, because he was trained to be a criminal, he has no right to be a detective. The Plateau Auberge Serial Murders Case will, therefore, be his final case, and he will not let himself be talked out of his decision—not even by Toto.
Ron adds that, because the case is strongly connected to the M. Family, one of the invitees may work for them. He and Toto re-examine everything: In the wine cellar, Ron wonders why the culprit risked using the fire extinguisher from the hallway and did not take one of the wines instead, especially considering that newer fire extinguishers contain powder, not foam. And in front of Gardner's door, Ron finds a bloodstain. Ron and Toto then check the flowerbed, as the flowers for Gardner's crime scene were likely taken from the garden. Indeed, some flowers have been plucked, and Ron and Toto keep wondering why the murderer is so fixated on mimicking the food.
A moment later, Lily hurries through the garden because she wants to walk down the mountain. When she is about to walk past a sign saying "Beware of landslides ahead!", Mia and Dan urge her to stop. Toto asks her why she is being so reckless, and Lily says she believes the culprit has a gun because she heard an explosive sound from Gardner's room when he died. Hearing that, Ron solves the case.[164]
Thereafter, everyone assembles in the dining room, and Toto presents Ron's deductions: Gardner was not stabbed inside his room but in front of it. With his last strength, he locked himself in his room and grabbed a flower to hint at his killer. The culprit witnessed that through the window and took flowers from the garden, put them in a balloon, and slipped the balloon under the door. They then inflated it until it exploded, covering Gardner's body in flowers and making the crime scene look like the edible flower salad. Because of that, the murderer had to continue basing the crime scenes on the dishes.
Gardner did not speak Japanese. The flower he grabbed before his death is called "oniyuri" in Japanese—and "tiger lily" in English. Because Lily could have easily picked the lock of Gardner's room, Gardner could have only meant Tiger Dan. Furthermore, the culprit used the fire extinguisher from the hallway because they could not open a wine bottle: They could not get a corkscrew because Sakai was in the kitchen. They also could not break a bottle because it would dirty their clothes; they could not change as they had no more clean clothes: They had to change after fighting Sasaoka in the bath. All this indicates that Dan is the culprit: Sakai had access to a corkscrew after all, Mia brought a lot of clothes, and Lily cannot read Japanese and, thus, could not have known that the fire extinguisher contained foam, not powder.
Dan confesses that he killed so many people to reawaken Ron's Moriarty roots. That Ron could replicate Dan's criminal mind to solve the case shows that he still has a criminal's heart after all. Dan also wanted to use this opportunity to eliminate everyone involved in the Jim Gore Murder Case because the M. Family leaves no trace of its activities.
Ron freezes up when Dan says he is and always will be a Moriarty and criminal, but shakes himself free when Toto tells him to get a grip and that he noticed that Dan is lying although he cannot figure out why.[165] Ron does not understand what Toto means, and Toto points out that it is weird that Dan wants to kill everyone involved in the Jim Gore Case. After all, the M. Family only eliminates those who failed them and that crime 17 years ago was a success.
Dan tells everyone that the case was a failure from the M. Family's perspective because Jim Gore was supposed to be kidnapped, not murdered; they wanted to use him and his research to gain great wealth. For his mistake, Eliot was killed, and when Dan takes out his gun and points it at Mia and Lily, he triggers Ron's memory of his father's death. He also remembers that Eliot once told him to pursue his own path, unbound by his heritage.
Ron regains his resolve and confronts Dan: The reason why those involved in the Jim Gore Murder Case were not eliminated 17 years ago is that the M. Family did not know about their involvement until recently, having been outwitted by Eliot. Furthermore, Ron deduces that Gore must still be alive and was likely switched with a dummy corpse in the hospital's garden. After all, his father would always make sure that nobody got hurt and would have never handed over Gore or killed him. Dan confirms everything.
Ron starts to laugh and tells Dan that his plan to convince him to stop doing detective work has failed. Instead, the case made him even more determined to use his intellect to fight the M. Family. Toto orders Dan to drop the gun, but he refuses. Before he can pull the trigger, the teddy bear on Mia's lap starts to move and talk, introducing himself as the M. Family's eldest son Mylo Moriarty.[166] He intended to watch everything silently but decided to reveal himself after Dan's plan failed.
Ron orders Lily, Mia, and Sakai to cover their ears; if they do not hear any more about the M. Family, Mylo could let them go. Although Mylo praises Ron for the idea, he insists on eliminating everyone present.
Then, Ron's body starts to fail him; he starts to shake and sweat and sinks to his knees. Mylo concludes that this must be a side effect of the medication Ron is taking to counter Kill on Sight: The medication redirects Ron's murderous intent to his innards, and he will eventually succumb to the side effect if he keeps taking it. Furthermore, because Ron resisted Dan's poor attempt to convert him, Mylo gives him a reward: The person who modified his body is an M. Family member—and a spy at BLUE.
Afterward, Mylo sets off the bomb planted in the Auberge Reunion for the main dish: three types of roast game. The building quickly catches fire, and Dan picks up Mylo's teddy bear and escapes. Toto helps Sakai, Lily, and Mia out before he runs back for Ron. However, by that time, the fire has advanced so much, they cannot get out anymore.
Just when they have resigned to their fate, Spitz arrives with a helicopter and saves them. BLUE received a set of coordinates from an anonymous tipster, and Spitz was sent out because he was closest to the location.
With BLUE's help, Mia, Lily, and Sakai go into top-secret protection to ensure the M. Family cannot get to them. And, since the case, Ron complains about his father and says that it is only natural that his "worthless" father got killed. Nevertheless, Ron often looks at the photo of Eliot he got from the auberge with a smile on his face.[167]
Fortuneteller Prince Murder Case
Spitz and Toto visit Ron at Pot Coffee while he is working a shift there. Spitz says he was unable to uncover anything about the M. Family spy at BLUE, and Ron decides that he has no other choice but to go to BLUE himself to hunt the mole. After Toto and Spitz remind him that he cannot go there as he was expelled, Ron calms down and takes their orders.
Although Spitz orders a cola and a coffee, Ron gives him a brown sugar drink, having deduced that Spitz only wanted a brown drink. Spitz admits this and then tells Ron and Toto about the Fortuneteller Prince and his Mega-Boost Fortunetelling; he ordered brown drinks because his Mega-Boost items for today included "brown drinks." He also bought three tickets to a signing of the Prince's new book and invites Ron and Toto to come with him.[168]
On the day of the signing, Ron, Spitz, and Toto go to the venue, an inn, and wait for their number to be called. Totomaru is called first, and when he returns, Ron tells him that the Fortuneteller Prince's correct guess about his good luck was only a trick. However, before Ron can explain what he means, a group of fans discover Lost Koala's corpse in the garden.
Ron and the others inspect the body, and Toto contacts Amamiya. The Prince joins them, expressing his sadness over losing a devoted fan and his willingness to help with the investigation. Still, Ron is wary of him.[169]
When the police come, they conduct Lost Koala's autopsy: She died of strangulation about two hours ago, just before the start of the invite-only party. Witnesses saw Lost Koala arrive early and leave her seat right before the signing. Ron adds that it looks like Lost Koala was strangled with a belt-shaped cord, but such an item was not found anywhere. It might have been flushed down the toilet, and the police will later check the surveillance cameras.
Toto tells an officer to make sure nobody leaves the venue, and after the officer leaves, the Fortuneteller Prince approaches Ron, Toto, and Spitz again. Ron tells him about "Toto's" suspicion from earlier: The Prince knew Toto is a police officer because he quickly searched his name, hiding his phone behind a fan, after Toto gave his name at the signing. Ron also points out the Prince's suspicious certainty that Lost Koala was murdered; the Prince replies that he knows she would have never committed suicide.
After Toto confirms that Ron has taken his medicine, they and Spitz head to the Fortuneteller Prince's room to search for the murder weapon. There, they note that the heater does not work because its remote has no batteries. The Prince then arrives and tells them that he believes in Mega-Boost Fortunetelling "more than anyone" as he was once in a horrible plane crash and thinks he only survived because he had his lucky item with him. He, thus, claims that Lost Koala died because she did not have her lucky charm with her.
Ron continues inspecting the room and finds out that it has access to the courtyard, making it easy for someone to move a corpse to the garden. And if the culprit wore a kimono, they could have easily repaired it, in case it was slightly damaged during the transport. Knowing that Ron and the others are suspecting him, the Prince reminds them that he is friends with politicians: If they have no evidence to prove his guilt, he will tell his friends how he was harassed by the police.
Later, Toto scolds Ron for eating too many sticky buns as his throat will dry out. When he hears that, Ron figures out where the murder weapon is.[170]
While the Fortuneteller Prince is doing a live broadcast from the inn, Ron, Toto, and Spitz search his room, wearing overalls and animal heads to hide their faces from the Prince's audience. When the Prince notices them, they explain that they only wanted to check whether the murder weapon is underneath a cushion or elsewhere. The Fortuneteller Prince allows them to search; meanwhile, his live broadcast continues.
The Prince muses that, if he were the culprit, the murder weapon would be his Mega-Boost ribbon; however, they were all handed over to the forensics team already who analyzed them and found nothing. He then uses this opportunity to advertise his ribbons to his audience before he notes the room's surprisingly high temperature. After all, it is currently very cold in Tokyo. He then reaches for a cup of tea, and Totomaru confronts him about his choice, asking him why he neither chose the coffee (his Mega-Boost item is "brown drinks" after all) nor decided to use the AC to lower the temperature.
The Fortuneteller Prince can make an excuse for why he did not pick the coffee (the heat dulled his judgment) but before he can make another for ignoring the AC, Totomaru exposes his true reasons: The Prince killed Lost Koala with one of the Mega-Boost ribbons. He removed the batteries from the remote, wrapped the ribbon around it, and submerged the batteries in the coffee bottle, effectively hiding the murder weapon. Ron then reveals that they already gave the coffee bottle to forensics: The bottle on the Prince's table is a fake filled with brown sugar.
Defeated, the Prince confesses to murdering Lost Koala; she wanted to defame his Mega-Boost Fortunetelling, and he could not allow that. He asks why it even matters that he was only using a trick as long as his "fortunetelling" made people happy. Toto then informs him that forensics found no conclusive evidence on the ribbon; they, therefore, had to make him admit to his crime during his live broadcast as he could not contradict his own fortunetelling in this situation. They also surrounded the room with heaters to make him thirsty. The Prince is subsequently arrested.[171]
Severed Head Balloon Case
While Ron is fighting against the side effects of his Kill on Sight medication,[172] Toto texts him, asking if he wants to meet up with him and Amamiya. Ron replies that he cannot see them right now.[173]
Later, Toto texts Ron again. This time, it is about the case he and Amamiya are spontaneously investigating, but Ron does not write back.[174] He reads the message though and forces himself to go to the mall to meet Toto and Amamiya despite being drowsy.[172] He arrives right after Amamiya and Totomaru get the confirmation that there was indeed a floating severed head,[175] carrying a bag with a Kamonohashi Sweets ice cream delivery. When Amamiya and Toto ask why he is wearing pajamas, he explains that he was in a hurry to bring them the ice cream before it melted.
Excited, Amamiya accepts the ice cream, and while she is distracted, Toto gives Ron a run-down of the case. After Toto shows him a photo of the company building, he receives another call from forensics. They found a match for the blood sample: Omoda, a CEO and the missing person whose case was assigned to Amamiya. She informs Ron and Totomaru that Omoda vanished at his workplace three days ago after receiving an anonymous death threat. He disappeared without a trace although the company's new building is equipped with a state-of-the-art security system.
Amamiya points out the building as it can be seen from the mall's roof. Seeing it, Ron solves the mystery and says that the severed head and the balloon met by accident. However, instead of telling Totomaru his deduction, he leans a half-eaten popsicle against a rise as a hint and tells Toto that he has already met the culprit. Wishing Amamiya and Totomaru good luck, Ron leaves.[176]
Later, Ron wakes up in front of the Maison du Kamonohashi where Toto finds him. Ron explains that he took his medication a few days ago and, lately, its side effects have not been subsiding after sleeping for a day anymore. Earlier, he had to force himself to go to the mall after receiving Toto's message. On the way back, he fell asleep in front of his apartment building. Toto suggests to stop taking the medication, but Ron refuses. He also tells Toto that they have received their next case: One that is very important to Ron.[177]
Twin Prison Locked Room Murder Case
Toto asks Ron what he means, and Ron shows him an article by Chicory about the discovery of a seven-year-old corpse in the Okutama Mountains. Shortly afterward, they head to the Moon Prison.
On the way, Ron explains that the prison has a twin building, the Sun Prison in England. 70 years ago, someone was murdered there too, though that locked-room murder has never been solved.
When Ron and Toto arrive at the Moon Prison, they meet Amamiya who allows them to help with the case and briefs them: Seven years ago, Juntaro Mihane bought the prison and locked himself inside it, wanting to reach the goal of the organization he belonged to: connecting with space. Jarr Jorr, the Two Prisons' architect, was part of it too. However, Juntaro was killed not long afterward. His family filed a missing person report back then, but he was never found and eventually declared dead.
Two weeks ago, Juntaro's wife Youko Mihane, his son Kiyotaka, his brother Junji Kaji, and his servant Kaki Sakanoue went to the Moon Prison. Because the prison was locked and only has one unique window they did not want to damage, they had to contact the owner of the Sun Prison. The Moon Prison's key was destroyed in a house fire seven years ago; however, as the two prisons are twin buildings, their keys are identical. The Sun Prison key just arrived, and when Juntaro's family returned to the Moon Prison and unlocked it, they found the corpse. Curiously, they did not see it two weeks earlier looking through the window. Kiyotaka even has photographic proof of that.
Afterward, Amamiya leads Ron and Totomaru inside the Moon Prison to show them that it is a perfect locked-room mystery: If the building is locked, it is impossible to enter or leave it, or for a corpse to disappear or re-appear. An officer remarks that "locked rooms" and "impossible crimes" do not exist outside of fiction and that it might have only been an accident. When Amamiya says that it would be nice to declare it an accident, two hooded people arrive and object: Fin Fennic and her assistant Shachi who want to assume the direction of the crime scene.[178]
While Amamiya briefs Fin, Ron and Toto watch them from afar, and Ron points out that, like Mylo said, a BLUE instructor suddenly appeared before him. Thus, he and Toto need to be careful around Fin as she may be the M. Family spy. Then, Shachi and Fin approach them. Ron suggests to Fin, for old times' sake, that Totomaru will compete with her to solve the Moon Prison's mystery, but she is uninterested. She informs him that she has heard of the rumor that he is illegally investigating and states that she will punish him without hesitation if the rumor is true.
When Fin is about to return to the prison, she stops and says that she has changed her mind about the competition and accepts it. Because Toto already examined the Moon Prison's interior, it is now her turn. With her Phoenix touch and Shachi's help, Fin thoroughly inspects everything and then declares, to Ron's and Toto's surprise and amazement, that she has solved the mystery.[179]
Fin then gathers everyone to tell them what happened: Neither the culprit nor the corpse entered the prison in the last seven years. Juntaro's corpse was simply hidden behind a dummy wall made of foamed styrol. The blocks were likely connected via a cord that was threaded through the chimney; its end was stuck out of it and fixed to ensure that it did not slip back inside. The culprit never wanted anyone to discover Juntaro, but when they learned that his family was about to open the prison, they pulled on the string, lifting the blocks through the chimney and removing the dummy wall.
Fin deduced that there must have been a dummy wall because, in Kiyotaka's photo, the sunlight is striking a larger area of the wall than it does now. Therefore, two weeks ago, the wall was closer to the window than it was now. Furthermore, the murderer must be someone who knew the Sun Prison key was being delivered to Japan. Having solved the locked room's mystery, Fin and Shachi return to their guesthouse, leaving the Metro Police with the task of finding the culprit. Defeated, Ron drowns his sorrow by drinking multiple packs of brown sugar syrup.
The next day, Ron tells Toto about the Sun Prison Murder Case, having thought about it all night. Amamiya then calls Toto to inform him that Kaji's corpse was found in the Moon Prison: He was tied to a chair and stabbed to death, just like the Sun Prison victim.[180]
Immediately, Ron and Totomaru head to the Moon Prison; Fin and Shachi returned to investigate as well. Fin says that Kaji was likely stabbed after he was tied to the chair which means that the culprit was with him in the room. However, like in the Sun Prison Murder Case, a brass bar was mounted to the inside of the door, sealing the room from within.
Everyone then helps to thoroughly check the outside of the prison to find proof of whether someone entered or exited the building. In the end, Fin declares the case a perfect locked room right before Kiyotaka, Youko, and Sakanoue arrive.
Kiyotaka testifies that Kaji was fixated on finding Juntaro's killer because Juntaro had not left anything to his younger brother in his will. If Kaji could prove that Kiyotaka was his father's killer, he would get everything. Totomaru notes this must mean that Kaji went to the prison to investigate and then asks Youko for permission to smash the window. She agrees, and Kaji's corpse can finally be examined: He was not drugged, meaning that he was indeed killed inside the prison.
While Ron, Toto, Fin, and Shachi inspect the prison again, Sakanoue yells at them that it is their fault that Kaji died, as they had not arrested the culprit yesterday. Toto wholeheartedly apologizes to her; they only focused on solving the mystery, not apprehending the culprit, and now, another life was lost. His words open Fin's eyes to her own arrogance, and Fin allows Ron to help with the case—as long as he does not solve it because her father used to say that someone is only a detective if they solve the mystery; otherwise, they are only a bystander.[181]
Later, Ron and the others question Youko, Kiyotaka, and Sakanoue. Toto inquires if they know where the brass bar might have been stored, and Kiyotaka reveals that it was kept in a shed at their home. As he, Youko, and Sakanoue all had access to the bar, they are all suspects; this sends Youko into a panic, but Sakanoue is there to tend to her.
Fin and Shachi then travel to the Mihane estate to search the shed for clues, whereas Ron and Totomaru stay behind and talk to Youko who is feeling better again. She tells them that although Sakanoue has become a bit senile, she will not fire her because her late mother hired her and paid her in advance for the next ten years. Youko also admits that she wished they had never opened the Moon Prison. If the others had been on her side, she could have lived in peace.
Hearing this, Ron thinks about the prison door and the brass bar and solves the case. He also realizes that there is a reason why Fin could not figure out the mystery and that the current case is unconnected to the Sun Prison Murder Case; it is only a copycat crime. Ron then asks Sakanoue who has made a cooking mistake lately if Kiyotaka cooks for himself. Sakanoue replies that she has not made a mistake in thirty years.
A moment later, Fin and Shachi return, having found nothing in the shed, and Ron happily announces that he has solved the case.[182]
After Amamiya rejoins them, everyone gathers to listen to Toto's recitation of Ron's deduction: The culprit inserted a neodymium magnet in the brass bar, attached the magnet to the door, and left the room. Thereafter, they used a blowtorch to heat the door and the bar until the bar was heated to 330 degrees—neodymium's Curie temperature, the point that has to be reached for the material to lose its magnetism. The bar then dropped into the brackets and locked the door. Because the magnet's magnetism was destroyed, Fin could not detect it with her Phoenix touch.
Because the culprit used a blowtorch they were not familiar with, they hurt their left hand—and Sakanoue has been suspiciously covering her left hand. Sakanoue killed Juntaro and Kaji to protect Youko. Ron deduced that when he saw how much Sakanoue cares for Youko's well-being; oddly, she does not care for Kiyotaka though.
Sakanoue confesses that she promised Youko's mother to protect her daughter. Youko's mother did not like Juntaro, knowing that he would bring trouble, and she was eventually proven right when Juntaro began squandering the Mihane fortune for his religious group. And then, Kaji tried to pin his brother's murder on Youko and Kiyotaka to get his hands on the fortune. Sakanoue had to kill them to protect Youko and the fortune, and although she has been caught, she is content, as she fulfilled her promise and will die soon anyway.
Later, Fin tells Totomaru that he solved the case well and reveals that she and Shachi actually took an x-ray of the bar and confirmed the magnet's presence inside it before Ron figured out the mystery. She and Shachi then leave, and although Ron wants to talk to them, he cannot as he faints due to his Kill on Sight medication.
A few days later, Ron and Toto head to the airport where Shachi and Fin are waiting for their flight home. Ron tells Fin he solved the Sun Prison Murder Case. She remarks that it is a convincing solution; however, because he has no physical evidence, it cannot be accepted as an official solution.
Fin admits that she knows Ron wants something from her,[183] and he tells her that he is gathering information on the Bloody Field Trip Case and asks why she is interested in that case as well. Fin says she is interested in it for two reasons: First because it is a locked room case. Second because of Aimee's unusual actions. Last year, Fin saw Aimee entering the Bloody Field Trip's crime scene—and Hirsch tailing her. Fin later confronted him about that, and Hirsch claimed he wanted to check if he left anything there. However, Hirsch had nothing to do with the Bloody Field Trip because he was not in England then. Fin stresses that this changes nothing though as the case is already settled before she and Shachi leave for their plane.
Toto and Ron return to the Maison du Kamonohashi. There, Toto asks Ron why he did not inform Fin about the unidentified blood because she might help. Ron replies they cannot rule out that Fin is the M. Family spy and adds that he is thrilled by the current developments as he considers Hirsch a "formidable opponent."[184]
Missing Cabbage Case
When Toto arrives at Ron's apartment, he is surprised to see that Amamiya and Kawasemi are there too and asks Ron what is going on. After all, Ron wrote him a message about an urgent matter. Ron admits that he exaggerated to ensure that Toto would come because it is his birthday today. And when Chicory and Mofu join them as well, Ron reveals that he invited everyone to throw Toto a hot pot party. Toto is touched by everyone's effort and he thanks them for everything.
Then, Chicory tells everyone that she could not get any Chinese cabbage despite having been to three supermarkets. Toto is fine with not having any cabbage, but Ron and Kawasemi insist that Chinese cabbage is essential to hot pot, and Ron calls Spitz to search a bit farther away.
While they prepare the other vegetables, the television is running in the background; a news broadcast announces that a jewelry store in Tokyo was robbed this morning. Then, Kawasemi and Amamiya get into an argument about the hot pot flavor: He suggests using the hatchō miso he brought, but she insists on using the standard soy sauce flavor as they are in Tokyo. Ron ends the quarrel by telling them that the flavor was decided already: The hot pot will be brown sugar-flavoured.
A moment later, Spitz arrives; to everyone's shock, he announces that he was in 15 shops and none of them had any Chinese cabbage. Suspicious of the situation and not wanting to forgo cabbage, Ron, Amamiya, Mofu, Chicory, and Kawasemi get ready to investigate this case. Spitz and Toto, however, think they are exaggerating.[185]
After everyone agrees to Ron's plan to solve the mystery of the missing cabbage for Toto's birthday, they realize that they all know him by different names: Amamiya knows him as "Kamoo," Chicory as "Kamokyu," Kawasemi as "Kamosemi," and Mofu as "Kamonohashi." Ron explains that he sometimes does not feel like using his real name; Toto then thinks of a suitable nickname. Everyone accepts this explanation and decides to keep calling Ron by the name they know him.
They then review the facts, and Chicory says that cabbages have not been trending anywhere, but she found out that a greengrocer reported having seen a man in disguise buying all the cabbages. With that in mind, Mofu, Toto, Kawasemi, Amamiya, and Ron each make a guess. However, they are all dismissed.
Mofu thinks the culprit may need so much cabbage because they keep ruining them out of clumsiness (dismissed because no one is as clumsy as Mofu). Totomaru believes a Korean chef he knows may be the culprit as he always covers his face and may need that much cabbage for kimchi (dismissed because no one can make so much kimchi). Kawasemi theorizes that the robber on the news hid the jewels in a cabbage truck and later had to buy out all Chinese cabbages to retrieve the stolen goods (dismissed because the thief was caught and cabbages are cut up before they are displayed). Amamiya suggests that the culprit may be a farmer who wants to "erase" Chinese cabbage from the market to force shoppers to buy something else as a substitute, e.g. lettuce (dismissed because the farmer would not make any profit like that).
Ron says he also thinks the culprit may be a farmer: He may have gotten into a fight with his son who poured pesticides over the cabbages in his anger. The father then delivered the cabbages without knowing any better, and the son had to rush to buy out all the Chinese cabbages so that the reputation of his family business would not be jeopardized because of his anger-fuelled action.
Everyone is satisfied with Ron's theory. However, he insists that he is only an amateur and that Toto will solve the mystery. Stressed because everyone is awaiting his deduction, Toto reaches for a drink in Spitz's shopping bag and discovers multiple receipts which all show that Spitz has purchased dozens of cabbages in various supermarkets. Caught, Spitz confesses that he bought up all cabbages because he despises Chinese cabbage which shocks everyone.
Thereafter, everyone wishes Toto a happy birthday, and Ron brings the nabe hot pot to the table. The pitch-black brown-sugar-syrup-based hot pot garners many unnerved looks. Ron innocently says they agreed on hatchō miso in the end and wonders where the brown sugar came from. He suggests searching for the culprit, but Toto replies that they already know who it is. Ron praises him for the quick deduction, and Toto tells him to shut up.[186]
Invisible Blood Letter Murder Case
After Ron finds out that Amamiya practices archery, he becomes interested in checking out her dojo, the Shingen Archery Dojo, and arranges to meet up with Amamiya and Toto there.
At the dojo, Ron surprises Toto and Amamiya with his archery skills and even receives praise from Mayumi Nakamae, an instructor. Nakamae invites them to watch her pupils practice, and Ron explains to Toto what they are doing. Eventually, the practice is interrupted by Sabatora Nora who is chasing after a cat, Nekomi, who has run into the Shingen Archery Dojo's shooting range. Nakamae arranges for someone to give the signal—a clap—that everyone should stop shooting, but before Nora can grab Nekomi, she has already jumped over the fence. He runs after her, and the archery students and Nakamae inform Ron, Amamiya, and Totomaru about Nora's infamous incompetence as the district detective.
The next day, Ron and Toto return to the dojo after Shu Kotegawa's corpse is discovered there.[187] He died of asphyxia sometime between 10 p.m. and midnight after someone shot an arrow into his vertebrae; Akane Saien found his corpse this morning when she came to clean. Additionally, the culprit seems to have only taken Kotegawa's smartphone, and when Ron examines the body, he notices blood on Kotegawa's index finger. He seems to have left behind a dying message, but nothing is written on the ground.
Nora joins them at the crime scene, and when Totomaru inquires how he got in, Nora shows him and Ron his C-rank detective license. He explains that he received it through self-study which strengthens Ron's suspicion that Nora's license may be a forgery; after all, Nora does not seem to be a skilled detective at all. Thereafter, Amamiya arrives and tells Toto that it is time to interrogate the dojo's members.
Neither Saien, Nakamae, nor Mikio Toban have an alibi for the time of Kotegawa's death, and all of them testify that they have never seen the arrow with which Kotegawa was killed. However, Toban says that he cannot be the culprit, as they are evidently a skilled archer and he is currently in a slump. He was also running around in the area last night, and when he passed by the dojo, he heard someone practicing there; he did not take a look but knows from the sound of the bow that it was nobody he knew.
Nakamae, Toban, and Saien then speak about the upcoming tournament where Kotegawa was meant to be the ochi. There are names for the positions where the archers stand and when they fire: Oomae, niteki, naka, yonteki, and ochi. Suddenly, Nora declares that somebody is lying but cannot elaborate, and although Amamiya drags him away for the "nonsense" interruption, Ron agrees with Nora, having solved the case just now.[188]
After Nora returns from having received a lesson from Amamiya and makes an outrageous deduction, Totomaru steps forward and reveals that he knows what occurred: Kotegawa did not write a dying message, but the blood on his index finger hints to his killer as it points out an archery position, niteki. There is nobody at the dojo associated with that position; however, the name can also be read as nakamae (before naka) which means that Nakamae is the culprit.
Immediately, Nakamae admits her guilt and says that she killed Kotegawa because he said something that "dirtied" the honor of the Shingen School. Although Ron figured out the meaning of Kotegawa's blood message, he was unsure of Nakamae's motive, but when Nora remarks that she is lying, Ron understands what happened: Nakamae did not murder Kotegawa; it was an accident. She was practicing with him because she is in a slump and used a weaker bow to correct her form; for that reason, Toban did not recognize its sound. Nakamae accidentally shot Kotegawa when he was in the shooting range; she had not heard his clap as he was standing to her left, and she is deaf in her left ear.
Nakamae confesses that Ron is correct. She asked Kotegawa to help her, and when she killed him by accident, she removed all traces of their practice. She even put the blood on Kotegawa's finger to make the accident look like murder, as she wanted to be a "peerless archer" to the end instead of a "worn-out archery instructor."
Afterward, Ron and Toto speak to Nora about his talent for detecting lies. Toto, on Ron's behalf, asks him if his skill has anything to do with crows, and Nora replies that he hates crows since he was attacked by one as a child. Ron realizes that Nora's fear of crows must amplify his lie-detection skill. This excites Ron because Nora could be useful in the future.[189]
Coin and Carving Murders Case
Bored and jealous because he read that Fin recently solved an ancient pyramid's looked room, Ron is lying on his floor when Toto visits him. When Toto hears about Ron's frustration, he tells him about his current case, the Coin and Carving Murders Case: A serial murderer has been leaving foreign coins in their victims' bodies and carving numbers into their abdomen. Further, the victims' only commonality is the fact that they are in their thirties or older.
Just when Toto finishes telling Ron about the case, Amamiya calls him. She wants him to meet a visitor in her stead, Hirsch; he was invited to Japan by the Metropolitan Police Department and the Tokyo Seaside Medical University to lecture them about his techniques for solving cases through autopsies. The timing makes Ron and Totomaru suspicious: After all, Mylo said they would meet the BLUE spy soon, and Fin stated that Hirsch was behaving oddly around the crime scene of the Bloody Field Trip Case.
Ron and Totomaru meet Hirsch at the Seaside University. Ron tells Toto that Hirsch was a murder suspect 15 times but was never proven guilty due to a "nice and tidy" lack of evidence; Hirsch also once tried to kill Ron when he was still a student at BLUE, though Hirsch insists this was a mere "prank." Toto then receives a call that another body with a carved number was found. When Hirsch hears that, he gets permission to investigate the case as well and "employs" Ron as his assistant.[190]
Ron, Toto, and Hirsch head to the river terrace where Ryu Yanobe's body was discovered. Ron examines the corpse; everything is the same as with the previous victims, and Yanobe seems to have been killed elsewhere and then brought to the river later. Hirsch agrees with him and states that he wants to perform Yanobe's autopsy. Afterward, they head to the Metro Police's headquarters.
While Totomaru talks to Yanobe's wife and tries getting an analysis permit for Hirsch, Ron and Hirsch wait in a conference room, and Ron asks him why he wanted him to be his assistant. However, Hirsch does not give a clear answer, and before Ron can inquire further, Totomaru arrives and announces that Yanobe's autopsy is scheduled for today; he did not get the permit for Hirsch though as a surgeon is already assigned to the case. Hirsch then runs out in anger.
Later, when Ron and Toto are at a restaurant, Toto learns that a corpse was found at the Seaside University. They immediately go there, and although Toto could not reach Hirsch, he still arrives. Because there are now two corpses that need to be autopsied, Hirsch insists to help and even pulls out his detective license to speed up the formal procedures. Ron asks how Hirsch could know about the fifth body,[191] and Hirsch replies that he was simply passing by.
The next day, Ron, Toto, and Hirsch meet up with the case's surgeon Nagaoka for the double autopsy. Nagaoka's proposal to take turns examining the corpses is overturned by Hirsch's persistence to perform both autopsies at once; however, Ron and Toto will watch over the autopsies.
Ron and Nagaoka handle the fifth victim, whereas Totomaru and Hirsch examine Yanobe. During the autopsies, Hirsch says that the serial killer might have killed before and asks whether there was an unsolved murder before the Coin and Carving Murders began. Totomaru replies that a doctor was stabbed in Tokyo a while ago. Oddly, there is no coin inside the fifth victim, but one was placed inside Yanobe. Toto also notices Hirsch taking something out of Yanobe's body and hiding it, but Hirsch denies it when Ron and Toto later confront him. And while Ron and Toto ponder why Hirsch might have taken that item, Ron solves the case.[192]
At night, Ron and Totomaru wait for Hirsch to arrive in the morgue. When he does, Toto states that the fifth victim was not murdered; he died of a congenital heart disease, and Hirsch carved the number into his abdomen to make him look like one of the serial killer's victims. Therefore, Toto thinks Hirsch must be the culprit, but Ron and Hirsch tell him that he is wrong: Hirsch is not the murderer; they will come soon though. And indeed, a moment later, Nagaoka enters the morgue.
Ron and Hirsch then present their deductions: The culprit carved numbers into their victims and hid coins within them because they wanted to retrieve the corpses. After all, the numbers would hint at a serial killing, and the coins would make autopsies a must. The culprit could, thus, be no one else than the case's forensic scientist, Nagaoka. Furthermore, the numbers were carved into the victims' lower abdomen to conceal their appendicitis scars. The doctor that was murdered a while ago was the gastrointestinal surgeon who performed the victims' surgeries and he had hidden something within his patients' bodies that Nagaoka wanted to retrieve.
Nagaoka confesses that he killed the doctor after he learned that he stole the diamond that was made of his wife's ashes. Afterward, Nagaoka went on to find and kill the doctor's patients to locate the diamond; the coins are keepsakes from the trips Nagaoka took with his wife. Hirsch then reveals that he did not find the diamond inside Yanobe; he tricked Nagaoka into admitting his crimes. Because of his Kill on Sight medication, Ron subsequently faints.
A few days later, Ron and Toto meet up with Hirsch again at the Seaside University. Ron tells Hirsch he was certain that his "odd" actions were to catch the serial murderer when he insisted on the dual autopsy. When Toto asks Hirsch how he prepared the faux victim, Hirsch says he asked the dead man's family for permission. He then offers to give Ron more information on the Bloody Field Trip Case:[193] He had been fishing in the mountains for his vacation when Scotland Yard asked him to perform the autopsies. Intrigued, Hirsch agreed, but although the victims were skillfully killed, there was nothing remarkable about the corpses.
Hirsch thinks that the Bloody Field Trip Case is only noteworthy because someone erased the data of a blood sample found at the crime scene and spread the rumor that Hirsch was overseas when the crime happened. When Ron tells him that the M. Family might have been involved in the case, Hirsch backtracks and says he and anyone else should ignore the case, as he thinks no one should pry into the M. Family's matters. He adds that whoever told Ron and Toto about the rumor that he was out of state back then is likely an M. Family member before he leaves.
Sometime later, Ron and Toto discuss Hirsch's words and Ron's time at BLUE. Just after Ron states that he did not have any friends at that time, someone knocks on the door and collapses onto the floor when Ron opens it. The man calls Ron "cold" as they used to be friends at BLUE right before he passes out.[194]
Obon Dance Murder Case
Subsequently, Ron and Toto take the man to a hospital. He was, apparently, in a hit-and-run but because he is only mildly injured and does not want to file a police report, Ron suspects that he is lying; he also cannot remember him at all from his BLUE days. The man then joins them and introduces himself as Elmer Stingray. He claims that although he had transferred to BLUE only three days before the Bloody Field Trip Case, he and Ron became good friends, and Ron even accepted Elmer as his investigative partner. Further, Elmer spent the last five years tracking down Ron because he vanished after his expulsion.
Still suspicious, Ron decides to keep Elmer close for now so that he and Toto can gauge him properly. They show him around and eventually find an Obon festival and agree to attend it.[195] There, they run into Chicory who is gathering material on summer festivals. Because Chicory calls Toto "Officer Isshiki," Hiiragi, the manager of the famous singer Nana Haruno, approaches him and asks for a favor: 15 years ago, when Haruno performed at this festival as well, she received a death threat. Though she has received no such note this time, the culprit has likely been released from prison by now, and Hiiragi fears that they might still return for revenge. Ron, Toto, and the others agree to help and watch the venue.
During Haruno's performance, Totomaru mistakes fireworks and a laser light gun for a gunshot and a real weapon. A moment later, all lights go out and a scream rings through the loudspeakers. Ron, Elmer, and Totomaru hurry to the stage and discover that Haruno was stabbed.[196]
Haruno, in critical condition, is rushed to a hospital, and Hiiragi accompanies her, whereas Ron and the others stay behind and investigate the case. The murder weapon was stolen from a takoyaki booth, and a man from the neighborhood association turned off the lights for 30 seconds at 6:15 p.m. because he received a message from Hiiragi. However, they find her phone in the trash, and Hiiragi testifies that she lost her phone before Haruno's performance.
Afterward, Ron and the others speak to the musicians that were on stage with Haruno. Each of them—Tsutsui, Kimura, and Tateishi—plays an instrument that requires both hands. Thus, none of them could have stabbed Haruno without stopping to play, and the music continued throughout the attempted murder. They also did not notice anyone coming on stage during the blackout.
Ron, Toto, Elmer, and Chicory then discuss the case. Elmer believes the culprit from 15 years ago might be one of the musicians, pretending to be a local. Chicory mentions that person also used to gift poisoned chocolate to other idols, and while she checks the previous case again, Toto calls Hiiragi for further information: Back then, a box cutter blade and a bullet were sent to the office of Haruno's agency back then. The bullet also reminds Hiiragi of the earlier commotion. Chicory returns and announces that the old culprit is already dead.
Determined to identify the new culprit, Totomaru attempts to play the musicians' instruments one-handedly and, by chance, discovers that one of Haruno's false nails is lodged deep inside the stage's paving stones. Ron then solves the case.[197] Right afterward, Toto receives a call from Haruno's hospital that she regained consciousness, and Ron instructs the hospital to get Haruno a bodyguard as the culprit will try to finish their business.[198]
Ron and the others hurry to the hospital and can stop Hiiragi just in time. She was hiding under the stage during Haruno's performance. The blackout was meant for a costume change, but when the lights went out, Hiiragi stabbed Haruno instead. Hiiragi gave herself away when she mentioned the gun commotion: If she had been in front of the stage as she claimed, she would have known that Totomaru had made a mistake and there had never been a gun. Furthermore, Hiiragi asked for Toto's help protecting Haruno because she had not planned to kill Haruno. However, when Haruno mentioned that she had given away the candy she received back then to children, Hiiragi decided to murder her.
Hiiragi admits that she wants to kill Haruno because she was one of the children who got candy. She gave hers to her bedridden mother; she died not long afterward, and Hiiragi believes that the candy must have been poisoned. Haruno woke up in the meantime and now reveals that she did not give Hiiragi the candy that a fan gave her: When Hiiragi came to Haruno, she had already run out of candy and given her other sweets as a substitute. Shocked, Hiiragi apologizes to Haruno.
Thereafter, Ron, Totomaru, and Elmer head home, and Elmer says he will stay in Japan for a while before they part ways.[199]
Invitation From Mylo and Bloody Field Trip Case
Days later, Ron and Toto talk again about whether Elmer might be the M. Family informant when a courier arrives with a letter from Mylo and an invitation to a cruise.[200] Mylo writes that the people connected to BLUE Ron has met lately will be on that ship as well; one of them is the M. Family informant, and Ron will have to identify them during the cruise. However, if Ron declines the invitation, he will never learn the truth about the Bloody Field Trip Case.
Although the cruise will be a trap, Ron still insists to go, as he does not want to lose his only chance to clear his name and rid himself of Kill on Sight. He will not go unprepared though and requests Spitz to speak to Aimee and find out if she discovered anything new.
Later that day, Ron and Toto head to Pot Coffee. There, they not only get a call from Spitz telling them that Aimee has no new information but also notice Winter observing them.[201] Ron and Totomaru rush out, and while they cannot catch Winter, they see that they have left them the original file about the Bloody Field Trip Case. Thereafter, they and Spitz regroup at Ron's apartment and discuss the file's contents.[202]
Elmer did transfer to BLUE three days before the Bloody Field Trip though Ron did not register him, and Hirsch was indeed on holiday when the incident occurred. By the time Elmer transferred, Ron had been chosen for the joint investigation with Scotland Yard and already located the murderers' hideout. Ron then received a locked room mystery from Fin, and after he got a pack of brown sugar syrup from Shachi, Ron spent the next three days in an underground room pondering about his homework; he even fell asleep from exhaustion at some point.
Ron handed in his homework and immediately headed to the hideout,[203] an abandoned factory. He arrived at 4 p.m. and although he initially wanted to wait for the police to come, a child's cry drew him inside the hideout. This was a trap though, and the criminals were waiting for Ron. While he fought them, he blacked out and woke up when he heard Big Ben chime at 5 p.m. Scotland Yard then found him surrounded by corpses and holding the murder weapon.
Fin was put in charge of the investigation because the incident was a locked room mystery. She determined that only Ron could have entered or left the factory during the time of the crime. Hirsch autopsied the bodies and stated that all criminals died when Ron was unconscious; the bodies also had not been moved. Their evaluations led to Ron's conviction. Additionally, the mysterious third party's blood was found on Ron's vest.
Having now read the full file, Ron has four theories about what could have happened: Fin might have lied that it was a locked-room scenario. Hirsch might have falsified the estimated time of death; he could have killed the murderers elsewhere and later brought them to the factory. Shachi might have mixed some hallucinogen into the brown sugar he gave Ron; the drug made Ron do things while he was unconscious. Lastly, Elmer disguised himself as a police officer to get access to the case file; he could have, thus, tampered with it and made it worse.
With the new information and his theories, Ron now feels ready to go on the cruise and find the informant.[204]
Tragic Cruise Serial Murders Case
After Ron gives his cat into someone else's care, he and Totomaru head to Yokohama to board the Precious Dolphin. There, an attendant familiarizes them with the ship's layout and offerings before she hands them the key card to their room, number 306, and mentions the welcome party that will be held in the Precious Hall later.
At the party, Ron and Toto encounter Spitz who sneaked on the ship disguised as a waiter,[205] though he is quickly identified as a stowaway and escorted off the ship.[206] They also run into Elmer, Fin, Shachi, and Hirsch.[207] Elmer claims to be on the cruise because he had a "hunch" that Ron would be on it, whereas Fin states her father invited her.
Later, when the Precious Dolphin departs, Ron and Toto receive an itinerary of the ship's course, along with a message from Mylo: At midnight in Bar Mermaid, someone will give them a clue about the M. Family spy. Ron and Toto, thus, head to the bar and survey the area; Hirsch is there as well. When it turns midnight, someone starts playing the piano, and a man dies after drinking poisoned wine.[208]
Hirsch calms down the bar's patrons to avoid mass panic and introduces himself as a forensic detective, Ron as his assistant, and Totomaru as a police officer to a waiter. The waiter tells them that it is the man's 40th birthday. For the occasion, his wife Rumi requested a song and a wine made in his birth year, and the bottle was already on the counter when the bar opened. However, the voice on the telephone sounded mechanical and male, meaning that someone else made that call. Ron examines the bottle and finds out that someone placed a false label over the correct one to conceal the fact that the wine was not made in the man's birth year.[209]
Thereafter, Ron and Totomaru return to their room and find the satellite phone Ron brought destroyed. Mylo calls them a moment later via the ship's phone to tell them that the informant killed the man and that they will murder a person every day until Ron has found them. The only way to stop the informant though is to kill them; for that, Mylo has provided Ron with a gun.[210] Angered, Ron proposes a safety measure to Totomaru before he goes back to the bar, and Toto talks to the captain, Todoroki.[211] When he joins Ron in Bar Mermaid, he reports that there is a network failure and the cruise will continue for now.
Ron wonders why the bottle's label was pasted over and not a bottle from the correct year was used. When Toto says that the M. Family can get wine from any year, Ron realizes that the culprit must have prepared one poisoned bottle of wine and multiple false labels. Upon learning the victim's birthday, they simply placed the corresponding false label on the bottle. It was, therefore, an indiscriminate murder, and the crime was only committed to give Ron a clue.
The next day, Ron and Toto find Fin and Shachi in the Whale Café. Ron asks Fin to tell him why she determined the Bloody Field Trip Case a locked room mystery; she tells him everything that was in the case file and adds that Ron behaved oddly on that day. When Ron asks Shachi why he brought so much brown sugar syrup, Shachi replies that he was making a lot of Japanese sweets back then. Before Ron can inquire further, someone screams for help, and when they rush outside, a woman crashes head-first onto the ground; she is tangled in ropes.[212]
Fin examines the woman and says that she will die as her cervical vertebrae are broken. Because she was dropped from the deck above, Ron and the others hurry upstairs and find rubber plugs by the door and a woman with ropes to her feet. Ron and Fin quickly realize what happened, and Fin explains it to the others: The culprit drugged the two women, college friends, and tied them up together; one was tied to the railing, whereas the other was dangled over the edge. When the woman on the deck regained consciousness, she used the knife that lay at her feet to cut herself free. As soon as the rope was cut, the other woman fell. The plugs were placed with the help of the ship's swaying and used to keep the door shut.
Afterward, Ron, Toto, Fin, and Shachi talk to Todoroki and return to their respective rooms. Ron points out that the informant is targeting pairs and forcing one to unknowingly kill the other, likely to make the situation more tragic and entice Ron to use the gun.[213] Toto comes up with a way to identify the spy: They refill the bottle used in the first murder with normal wine and offer it to the suspects (except Hirsch who witnessed the murder) to gauge their reactions. The culprit, knowing about the poison, might hesitate to take the offer.
Ron and Toto first extend the wine to Elmer who accepts the offer. However, he realizes that it is not a Flajolet before he drinks it. Elmer also says he has been rather seasick and quickly excuses himself and retreats to his room. Toto and Ron then run into Shachi and Fin; Shachi happily guzzles down multiple glasses, but Fin refuses the wine. Ron is satisfied with the results of Totomaru's test.
Done with the wine, Fin tells Ron and Toto that she found an A-rank detective license at the crime scene of the second murder. It is most likely Hirsch's, and Hirsch apparently also called away the receptionist during the time of the first murder. A phone line runs from the bar to the reception, and Hirsch might have used the phone to order the anniversary wine. Just then, Hirsch joins them, and when Fin shows him the detective license,[214] he confirms it as his. He noticed that it was gone in the afternoon. Shachi found it under the railing around noon, and when Fin examined the license, she determined that it had been on deck for less than an hour. Therefore, it is possible that the murderer retroactively left the license at the crime scene to throw off the investigation. Further, Hirsch states that the receptionist was gone back then because they were looking at his defective card key.
Fin says that she is suspecting everyone right now to be safe, though she cannot think of a motive. She wants to catch the culprit before they murder again, and when Ron asks why she is certain that there will be another murder, Shachi chimes in. Because the culprit has not been caught yet, it is only logical that they would continue.
On the way to their room, Totomaru says he wanted to tell the others that the M. Family informant is behind the killings. Ron agrees; it will be risky, but by informing the others, they might make it harder for the spy to continue. They proceed to admit everything to Fin, Shachi, Elmer, and Hirsch. They all agree to help. Elmer also says that Ron helped him when he got hurt at BLUE, and he now has to repay his "debt." Everyone then gathers in Fin's room to search for the spy together.[215]
On Elmer's suggestion, they head to the lobby on the sixth floor. Ron's plan is that they simply all stay together; after all, if they are gathered, the informant cannot make a move without exposing themselves. Hirsch reveals that one victim from the Bloody Field Trip Case was not stabbed in the heart like the others, and Fin questions whether Hirsch truly performed the autopsies back then before the conversation dies down.
Eventually, Hirsch finds a crumpled piece of paper. On it, the culprit has written "⬤ol 00:10 Third victim." Everyone comes together and determines that this must mean that another murder will happen ten minutes after midnight in a room whose number ends in "01." Because they only have 15 minutes to check six potential rooms, they split up: Toto goes to 101, Fin to 201, Shachi to 301, Hirsch to 401, Elmer to 501, and Ron to 601. They also agree to meet up again in the lobby at 12:20, regardless of what happens. They then hurry to their respective rooms.[216]
After checking their rooms, Ron finds Totomaru and admits that he never thought the code referred to a room number and that it was simply a scheme to separate everyone. He thought he could figure out the true meaning within ten minutes but could not; he then went to Toto to get a hint. Toto has no idea how he can help and only says he wonders why the passenger rooms are only on six floors when the ship has seven floors. His words make Ron realize that not a number was obscured but the word "pool."
Immediately, they head to the pool on the seventh floor. There, they find two people bound together back to back with tape, flipping themselves over, and fighting against drowning—and spot the culprit running away. While Totomaru jumps into the pool, Ron hastes after the informant. They manage to get away but leave behind a satellite phone.
Ron rejoins Toto at the pool, and the others arrive shortly afterward[217] because they noticed that the elevator stopped on the seventh floor. After Ron explains everything to them, Fin, Shachi, Elmer, and Hirsch state that there was nothing amiss in the rooms they checked. The people in room 201 were suspicious but cooperative, the guests in 301 scolded Shachi, and the ones in 501 offered Elmer tea.
Ron asks them to stay by the pool while he goes to check the final piece that proves who the informant is. Toto follows Ron to a quiet part by the stairs, and Ron calls Spitz to find out the results of a DNA test. When Spitz was briefly on the ship, he offered each suspect a glass; they all accepted and then returned the glasses to him. Spitz could take the glasses with him and then compared the DNA on the glasses with the DNA of the third-party blood on Ron's vest: It is Elmer's. Having now thoroughly confirmed his suspicions, Ron solves the case.
Ron is about to return to the others when Totomaru starts praying that they will be able to catch the culprit and return Ron's body to normal. This reminds Ron of their first encounter, and he thanks Toto for always believing in him. A moment later, smoke spreads and someone knocks Ron and Toto unconscious with a metal pipe.[218]
When Ron wakes up, he finds himself in the audience of a magic show held in the Precious Hall. The four suspects are unconscious in the front room, but there is no sight of Totomaru. And when the stage magician pulls out the gun Mylo left Ron, Ron rushes on stage and retrieves it. Mylo's mechanic teddy is then lowered down on a rope, and Mylo promises Ron that the passengers will be safe if he determines and shoots the spy.
Ron steps forward and says that only Fin could be the culprit: As a locked room expert, she could calculate the ship's swaying to ensure the rubber plugs would jam the door. She also declined the wine and would benefit from using a voice changer and making others believe someone with a "male" voice was calling. Ron, therefore, points the gun at Fin[219] but it is only a ruse to force Shachi into exposing himself. Ron figured out that Shachi must be the spy, i.a., because everything the culprit did turned suspicions away from Fin: The trick with the plugs relied too much on chance and the voice changer made everyone suspect a man, not a woman. Furthermore, Shachi drank so much of the wine to double-check it for poison. And when Shachi said the people in room 301 scolded him, Ron knew for certain that he was the informant: He and Totomaru had secretly changed rooms and were now staying in 301.
Ron also solved the Bloody Field Trip Case: Shachi drugged him and then changed the date on his phone. When Ron woke up, he believed three days had passed, not two, and headed to the factory where he lost consciousness. An imposter filled in Ron's place on the actual day of the exercise and treated Elmer when he got injured; some of Elmer's blood landed on his vest. The imposter then went to the hideout, killed the criminals, and dressed Ron in his bloodstained uniform before he stabbed himself and handed Ron the knife with his last strength.
Shachi confesses to his crimes[220] and takes out a gun. He forces the audience to stay seated and reveals that the doors are locked and cannot be forcibly opened without killing everyone in the Precious Hall. In ten minutes, a device will release nerve gas; only if Ron shoots the lock of the only door without a motion sensor, everyone will be able to escape. However, Totomaru sits on the other side of the door, tied up and wearing noise-cancelling headphones: Ron cannot alert him and he can only save the passengers if he kills his partner.[221]
Ron attempts to persuade Mylo to stop this; there is no reason for Mylo to punish Ron just because he hates his ancestor Sherlock Holmes after all. Mylo replies that he is not making Ron kill Toto because he is a Holmes but because he is a Moriarty: It is a trial he should have undergone years ago.
Elmer then wakes up prematurely because he hid smelling salts in his clothes and offers Ron his gun. Ron's gun only has one bullet, and he can, thus, not simply shoot off the door's hinges instead of the lock. And when Elmer reaches into his pocket and raises his hand, Shachi impulsively shoots Elmer's hand. Elmer does not have a gun though; it was a feint that made Shachi shoot the door. When Ron sees the hole in the door, he formulates a plan[222] and picks up a stool from the stage. He raises it upside down over his head but does not throw it. After his attempt to appeal to Shachi by telling him that he is disappointing Fin fails, Ron sets the stool down and shoots the door's lock.
Mylo is satisfied because Ron has now proven that he is truly a Moriarty and betrayed someone who trusted him. To everyone's surprise, Toto is not dead though: Ron used the principle behind pinhole cameras, and when he lifted the stool, he held it in a way that projected it through the hole to the wall on the other side of the door. The image of the stool reminded Toto of a shrine and his and Ron's first encounter when Ron deduced that Toto walked alongside the trees by the Wakana Shrine. Toto understood the message and leaned to the side. When Ron shot the lock, the bullet only grazed Toto and did not pierce his heart.
Ron taunts Mylo, telling him that he can "move forward without killing anyone."[223] While they stare at each other and do not pay attention to anything else, Shachi grabs Fin and runs out of the hall. The passengers follow suit. Ron and Toto pursue Shachi, and Elmer stays behind and brings the still-unconscious Hirsch to safety.
Ron and Totomaru chase Shachi to the deck where Mylo already waits for them. He shoots Shachi in the shoulder[224] and announces that the ship is now under his control. Shachi swears to Mylo that he will not fail him again, and Ron points out that Shachi did everything right but Ron still managed to solve everything. He has also deduced that Shachi is only working for Mylo because the M. Family took Fin hostage multiple times in the past. Fin then wakes up, and Shachi admits everything to her. However, before he can reveal what was done to Ron's brain, Mylo shoots Shachi in the heart.
Because Ron last took his medication too long ago and its effect has already worn off, Mylo's action triggers Kill on Sight.[225] Ron tries to persuade Mylo to shoot himself in the temple, but Mylo shoots Toto instead. As Kill on Sight is a kind of "hypnosis," you can shield yourself by filtering Ron's voice with a sound alteration device, and Mylo wears such a device in his ears.
Mylo sends his bodyguards away and throws a knife to Ron. He did not kill Toto as he still wants Ron to do it; as a "reward," Mylo will give Ron a flash drive containing all the information on what was done to his body five years ago. However, the fact that Mylo injured Toto angers Ron so terribly that the voice alteration does not work against Kill on Sight anymore. Ron compels Mylo to throw his gun into the ocean, and Mylo cannot resist and complies. He then hands him the knife and orders him to stab himself[226] but Toto can get through to Ron and stop him.
Ron breaks free of his trance. However, Mylo is willing to die if he can make Ron break the "detective's taboo" of never killing anyone and keeps taunting him. He even produces a second gun from his sleeve and shoots Fin. Ron struggles to suppress Kill on Sight and can only think of one way to stop himself: To everyone's shock, Ron stabs his vocal cords and collapses.[227] Then, Elmer and Hirsch arrive, and Mylo admits defeat. He throws the flash drive to Totomaru before he throws himself into the ocean.
Thereafter, Hirsch gives first aid to everyone still alive, the Precious Dolphin docks at the closest port, Naha, and the injured are rushed to a hospital.[228] Two months later, Ron is discharged,[229] though he is disallowed to speak until his throat is fully healed.[230] Totomaru[231] and Amamiya immediately go to see him, though Amamiya is quickly called back to work.
Ron and Toto return to the Maison du Kamonohashi. There, Toto gives Ron a letter Elmer left behind, though it is not from Elmer—it is from Romi Holmes, Ron's mother. She writes that Elmer has been working for the Holmes family since he was young, and she sent Elmer to Japan when he heard that Ron was targeted and wanted to help. Romi closes her letter expressing her hope that she and Ron will meet again before one of their funerals.
Mofu then arrives to announce that she finished analyzing the data on Mylo's flash drive. She could determine the cause of Kill on Sight and is confident that she can fix Ron's brain. Spitz also comes and informs Ron that he explained everything to BLUE, and the World Detective Alliance overturned Ron's punishment, meaning he can now take his test to get a detective license. All the good news overjoys Ron, and he collapses to the Floor of Sloth in absolute happiness.[232]
Ron Kamonohashi's Homecoming Case
Sometime later, when Ron can speak again, he and Toto are set to travel to BLUE to get Ron's diploma. Amamiya bids them goodbye at the airport; and because of what transpired the last time Ron and Totomaru travelled, Amamiya gifts them good luck charms. Chicory, Mofu, and Kawasemi did as well. After Amamiya leaves, Spitz Feier joins Ron and Toto, and together they leave for England.
At BLUE,[233] they meet Aimee in her office. She gives Ron his graduation certificate and congratulates him before she asks if he could substitute for an instructor who went missing. Ron declines and suggests that Totomaru takes his place instead; he himself will be Totomaru's assistant. Aimee and Toto, albeit reluctantly, accept.
Toto's first lecture does not go well; not only do most students ignore him, but also a monkey jumps on him.[234] Afterward, Ron and Spitz tell him that this is normal for new instructors at BLUE. And while Spitz goes to prepare for his next class, Ron shows Toto around the academy. They run into Hirsch but he quickly leaves, not wanting to be anywhere near them.
When Ron is about to bring Totomaru to the place with the best view in BLUE, they encounter two of Totomaru's students, Marsh Leipley and Udy Dietner. They wanted to prepare for their next class, but the door is locked. Because Ron lacks the special tools needed to pick the lock, Toto climbs on Ron's shoulders to look through the window above the door and spot Alissa Beaumont's lifeless body in the room.[235]
As the key is in the staff room and, thus, too far away, Ron and Toto decide to enter the room via the ledge outside. However, the room's window is locked as well, and someone also threw Alissa's head into the pond below. Ron immediately deduces what happened and he sends Udy and Marsh away to get the key so that he can tell Toto everything.
Marsh and Udy do not only return with the key but also with many other students who want to see Totomaru solve an apparent murder case. Toto tells the gathered mass that Alissa was not murdered; it was only a prank: Alissa hid in the storage space under the floor and stuck out her head; the "body" they saw was not hers but a dummy's. She likely planned to make her corpse "disappear" and spook Toto while they went to get the key from the staff room. However, Ron and Toto chose to enter the room from the window ledge. Alissa then threw the dummy's head into the pond, thinking that she could leave the room while they went to inspect the head. Again, her plan was thwarted because Ron still checked out the room. Alissa had used a sheet of false blood for her farce, but when she left her hiding place, the hole in the sheet became visible. She hastily had to pull the sheet under a pillar; this gave her prank away, as Ron noticed that the bloodstain had moved without losing its shape.
Thereafter, Toto opens the door. Even though Alissa should be inside, she is not: She attempted to escape via the ledge but did not get far because she became frightened, and she is now stuck on the ledge. Toto manages to pull her back into the room right before she slips and falls.[236]
Ron and Toto later return to Aimee's office where she thanks Toto for the "lesson" he gave the students. Aimee also reveals that she has known Ron since he was a baby because she and his mother Romi have been friends since their days at BLUE.
The next day, Ron reads on the news that three missing detectives were found dead. As it is Saturday, Ron and Toto do not need to go to BLUE,[237] but then Aimee texts them to see her at her office at 3 p.m. Surprisingly, they are not the only ones going to BLUE on the weekend: On the way to the school, they also run into Udy, Marsh, Alissa, Knight Bran Jr., and Billie Za Gozzila. Hatter Horn is already there and waves at them in panic when they arrive. He came to BLUE to talk to Aimee about his academic advancement plan, but when he entered her office, he found her collapsed at her table. Immediately, Ron and Totomaru rush to Aimee's office and discover that Aimee was shot and a strange video is playing on her laptop.[238]
Cryptid Serial Murders Case
Ron orders the students to stay back while he examines Aimee's body; with a heavy heart, he confirms her death. Aimee died two or three hours ago, and the bullet passed through her body and is now lodged in her chair. The murder weapon lies on the ground, empty of bullets.
When Ron and Toto are done inspecting the crime scene, Knight tells them that Aimee asked him to see her an hour ago. Alissa was also called by Aimee to help move Billie's pets,[239] and Alissa asked Udy, Marsh, and Billie to assist her.[240] Everyone, thus, deduces that whoever killed Aimee must have called them to BLUE, possibly so that they find her body. This means that Aimee's murder is a declaration of war to Ron, Totomaru, and the students.
Then, the academy's guard comes into the office, intending to ask Aimee whether the emergency isolation system is running. When it is activated, the system blocks internet and phone signals as well as pulls the drawbridge. Ron and Toto rush outside to check the bridge, but it was already drawn[241] and because only Aimee knew the isolation system's deactivation code,[242] they are now trapped in the school.[243]
Later, everyone gathers in a lecture hall to discuss why they might have been isolated at BLUE and how to proceed. Ron and Totomaru search Aimee's laptop to find a way to deactivate the emergency isolation system. Marsh offers to help as he specializes in cryptology. He manages to boot up the laptop with another operation system, though fails to disable the isolation system as its control is overridden by a third party. When Toto praises Marsh's abilities and calls him and the others the "future of detecting," Marsh admits that he does not want to become a detective at all as he faints when he sees blood or corpses.
The guard finds them and says that he is looking for the other students. Ron confirms with the guard that no one could have left or entered the school while he was away from his post; the culprit must, therefore, still be at BLUE and is most likely one of their group. They then hear Billie scream and follow the sound and her monkey to the courtyard: Udy lies there. Her lifeless body bears deep gashes, and a piece of paper saying "Chapter 1: The messenger from the sky Wyvern" is next to her.[244] Curiously, only her footprints are visible, and Udy's corpse lies in the middle of the courtyard.
Ron and Toto examine her body and determine that she died about 20-30 minutes ago. Not long afterward, Alissa, Hatter, and Knight arrive and are shocked by the scene in front of them; Alissa even faints. Billie, however, is nowhere to be seen. Marsh speculates that she might be in the hidden room under the north building as she was considering keeping pets there. Everyone heads to that room; the guard carries the still-unconscious Alissa.
On the way, the students and the guard talk about Ron Kamonohashi who used the room in the past. Hatter voices his hatred of him, as he believes that he works with the M. Family. In the hidden room, they find an ashtray with cigarette butts and strands of blue hair, neither of which belongs to Billie or anyone they know who is inside the school.[245] While everyone discusses what to do next, Alissa wakes up and immediately spots the tenth person under the bed. She wants to attack them, but Ron stops her and tells the person to reveal themselves. To everyone's shock, Chelsea Gadd crawls out. The students have not seen her lately because she was suspended for her obsession with the M. Family. Chelsea is also a fan of Ron Kamonohashi; a fact that rather disturbs Ron.
Without answering their questions, Chelsea leaves the room, and the others follow her to the courtyard. There, Chelsea identifies the paper lying next to Udy's corpse as a page from an M. Family book.[246] She learned about it from a special "Unsolved Mysteries" class; apparently, that book was left at several crime scenes connected to the M. Family.
Ron and Totomaru re-examine the courtyard before they search the building for clues. Ron also decides that he does not want to reveal his true identity for now as the students likely would not trust him if they found out. Thereafter, they go to the home economics room where the students and the guard are about to make dinner. Hatter joins them later and brings the food he hid in the classroom. When Toto remarks that he should have told someone if he wanted to go to the classroom, Hatter snaps at him.
Ron inquires why Hatter is treating "Officer Isshiki" so poorly. When she hears his name, Chelsea realizes that Toto is the police officer who was at the Nandan Observatory during the Island Observatory Murder Case and the one "responsible" for Grizzly's death. Hatter hates Toto for that. Upon hearing about Toto's involvement in that case, Alissa and Knight also turn against him and leave alongside Chelsea and Hatter.[247] Ron and Toto want to search for them and ask Marsh if he knows where they might have gone, but Marsh is strangely avoidant of the topic. Toto realizes that he seems scared to solve the mystery, and Ron points out that Marsh can actually see blood; earlier, he could bandage the guard without problem after all.
Marsh admits that he came to BLUE to become a detective. However, he buried that dream when he made a wrong deduction that led to the falsely accused attempting suicide. Marsh then tells Ron and Totomaru where the others likely are. Ron and Totomaru head to the roof first where they find Alissa crying over Udy. After they convince her to keep going on solving cases for her dead friend's sake, they bring her to the home economics room.[248]
Toto and Ron split up, and Ron heads to the library to look for Knight. He has been researching secret passageways to escape the school; while his search did not bring the desired results, it was fruitful in another, unexpected way: Knight found a picture of Ron in one of the books and realised who he truly is. As the case seems to be rather well-conceived and is very possibly connected to the M. Family, Knight wants to solve it before Ron to become BLUE's best detective ever. Ron says he will not go easy on him, then.[249]
Ron and Knight later meet Toto and Hatter who found Minigozzi. The monkey guides them to the locker room where they find a locker leaking water. Hatter quickly picks the lock, and they manage to rescue Billie on time; she was tied up and placed in the water-filled locker. A cover page from the Guardian of the Citadel has been left with her too. To their horror, it is "Chapter 3: The Terror within the Water Merman," meaning there was another murder while they were searching.[250]
Ron and the others hurry to the rooftop where they find Chelsea's corpse. The cover page of "Chapter 2: The Giant's Awakening Cyclops" lies next to her, and she curiously seems to have died by falling from a high place. They then split up: While Marsh and Alissa bring Billie to their classroom so that she can change her clothes, Ron and Toto as well as Hatter, Knight, and the guard will investigate the area. They also agree to meet up again in an hour.
Toto and Ron remain on the roof, and Ron discovers fresh marks on a pole. Though it seems like an "impossible crime," Ron is determined to solve it.[251]
An hour later, everyone reassembles in the locker room and shares their findings: Knight's team found no evidence that Chelsea fell to the ground, but noticed that the guard station was broken into and the sensors that detect entry and exit were destroyed. Ron and Toto discovered marks on a pole as well as a bloody body bag on the roof. Thereafter, they examine the third crime scene. Billie testifies that she went looking for her pet rabbit and cat earlier when she spotted Udy's corpse from a window and was attacked from behind right afterward. She was knocked unconscious and woke up later in the locker.
Ron lies down in the locker and finds strands of long, white hair inside. Knight then whisks Ron and Totomaru away to the rooftop where Knight asks Ron for his deductions. Ron states that he has not solved the case yet, though he realized that "everything will fall into place" if he figures out the trick behind "a certain person's actions." Hearing his words, Knight is sure that they are suspecting the same person, and says that he, "Ron Kamonohashi," could truly be a strong rival. A moment later, Alissa arrives on the roof, shocked to have heard that "Kamo Miele" is Ron Kamonohashi.[252]
Ron tries to explain himself, and although Knight vouches for him too, Alissa is convinced that Ron is with the M. Family and rushes to the others. Ron, Toto, and Knight follow her. On the way, they discover that the timetable instructor's train was moved and has since cooled down. Across two floors, they also find four marks on pillars and five on windows.
In the dining hall, Marsh and Hatter inform them that Billie and Alissa are not back yet: Alissa wanted to speak to Totomaru and went to the roof; Billie accompanied her. Ron, Toto, and Knight immediately go to search for them, and when Ron finds Chelsea's cigarette on the staircase and looks out of the window, he solves the case.[253]
Shortly afterward, Ron tells Marsh, Hatter, and the guard "Totomaru's" deductions: Billie is the culprit, and she used wire and the timetable instructor's train to kill both Udy (she was lowered to the courtyard with wires and stabbed there) and Chelsea (she fell from the raising bridge, and Billie used the train and wire to transport her body to the roof). After killing Udy, Billie used the secret entrance beneath her corpse to leave. During Ron's explanation, Knight sneaks away to rescue Alissa alone.[254] Ron and the others then search for him, Alissa, and Billie.
After Hatter tells Ron and Totomaru that Billie liked to go to the monument room, Ron realizes that Billie is targeting BLUE's best students. They head to the courtyard where they uncover the secret entrance under Udy's body. The guard stays behind while the others go down, in case something happens. By the time, Ron, Toto, Marsh, and Hatter find Alissa and Knight, Billie has drawn a significant amount of blood from them but has not killed them yet.[255]
Upon being confronted, Billie reveals that she neither anticipated Toto and Ron's arrival nor Chelsea's presence. Still, she managed to incorporate them into her plan; e.g. when Chelsea spotted her re-entering the school via the lowered bridge after she picked up a new pet, a pomeranian, Billie was swiftly able to devise a plan to kill her. Billie also "ad-libbed" a show for Ron, Marsh, Toto, and Hatter: To test Toto's reflexes, she has set up crossbows that will shoot arrows at the unconscious Knight and Alissa in a moment. While Totomaru goes for Alissa, Marsh jumps to save Knight.
Afterward, Billie flees, and Ron runs after her with Marsh. Although they cannot locate her, Ron knows that Toto and Hatter will. And indeed, right after Ron states that Billie seems to have "beat" them, lulling her into a false sense of security, Hatter and Totomaru catch her.[256]
A while later, the police arrive and take away Billie. Ron and Totomaru send the remaining students to the hospital before they meet up with Spitz and Winter who have been working together on a case. They then investigate the secret passageways beneath the school and discover the room from which the culprit in the Missing Detectives Case sent a video to the World Detective Alliance. In that room, they find a copy of the Guardian of the Citadel. When Winter sees it, they realize the culprit's true identity: Alice Moriarty.[257]
After they regroup elsewhere, Winter tells Ron and the others about their sister.[258] Two days later,[259] Ron passes on that information to the World Detective Alliance[260] and offers to help with catching Alice. The Alliance, however, declines as they do not want any "outsiders" near that case; they also pushed back the reinstatement of Ron's detective license by three months.
Although Ron is certain that the World Detective Alliance's "special team" will not have a chance against Alice unlike him, he chooses to take up their suggestion and return to Japan with Totomaru.[261] Before they depart, they return to BLUE to bid goodbye to Alissa, Hatter, Knight, and Marsh. Alissa in particular uses this opportunity to apologize to Ron but he does not hold her actions against her.
After Ron tells the students to take care of BLUE, they part ways. Class begins shortly afterward, and when the students begin texting Toto while ignoring their new instructor, he becomes upset and heads back to BLUE to "set them straight." Ron remarks that Toto is really "their teacher now."[262]
Maison du Kamonohashi Case
When Ron and Toto arrive in Tokyo, Amamiya waits for them at the airport. Ron asks her if she wants to drive to the Maison du Kamonohashi with them, but Amamiya tries to convince him to go elsewhere first. Her words only raise Ron and Toto's suspicions though, and Amamiya quickly admits that she cannot have them return to the apartment building because it became "cursed" in their absence.
A moment later, Kawasemi appears; as he is in Tokyo for business, he decided to surprise Ron and Totomaru at the airport. Because Ron has to go to the Maison du Kamonohashi and look into the matter as the building manager, Kawasemi drives everyone there.
At the apartment building, Ron is surprised to find the suggestion box filled for the first time since he became the manager. He reads through the notes, each detailing a supposed supernatural encounter. Though the reports sound too fantastical to be true, Ron is certain that neither of the residents is lying.[263]
Amamiya suggests visiting each scene from the bottom to the top. Hence, Ron and the others first head to the garbage room on the first floor. There, Takeko Suzuki testifies that she encountered a "huge snake" and saw its "coils moving around." She believes it is a monster from another dimension or a snake ghost. Kawasemi and Toto are sure that it must have been something else, and Amamiya scolds them for their "inflexible" thinking.
One floor up, they meet Chinatsu Sasaki who is delighted to see Ron again. She tells them that she heard a man's voice yelling "Kill! Kill! Kill!" from within Room 202, an empty apartment. She went inside to investigate, but no one was in the room. On a desk, she discovered the picture of a dead man which has since vanished. Sasaki adds that Mofu lives next to the vacant room. When she heard the voice, Mofu was inside her apartment with Chicory.
On the third floor, Juntaro Doi explains to Ron and the others that he encountered the ghost of a woman in the elevator when he got home late. She was covered in blood and holding a crucifix. Kawasemi inquires if he was sober that night, but Doi cannot remember. Amamiya still insists that all events must have paranormal origins, much to Toto and Kawasemi's frustration. Ron, meanwhile, ponders serenely about the case.
In the third-floor spiral staircase, Raita Daimon confides in Ron that he spotted a man hanging by his neck when he returned home from tutoring. By the time his mother arrived, the body was gone.
Thereafter, Ron is about to propose going to his flat now, but Amamiya insists they cannot as every room is cursed and dangerous. They then spot Chicory and Mofu walking by, and when Kawasemi and Amamiya inform them about the "tough" case they are investigating, Ron states that "Officer Isshiki" already solved it.[264]
Shortly afterward, Mofu and Chicory join them upstairs. Because they need to head to work soon, Ron and Totomaru quickly explain each mystery to them, Amamiya, and Kawasemi as they walk downstairs.
The "hanging corpse" Raita saw was, in fact, Kawasemi. Two days ago, he came to the Maison du Kamonohashi to see whether Ron had returned home and noticed that the "H" on the building's wall was crooked. Kawasemi then lowered himself from the roof to fix the letter. The "elevator corpse" was no other than Mofu who collapsed in exhaustion. An old wound opened in the process, splattering her with blood. The voice from Room 202 came from Chicory's digital recorder. She had entered the room by accident, believing it to be Mofu's, and worked a bit there until she realized her mistake. In her hurry, she forgot her recorder and a picture; she retrieved both later.
Lastly, Toto explains that the "snake" was the 100-m-long scarf Ron knitted during his five-year isolation. Ron placed the muffler in the garbage room to be picked up, but Amamiya took it away beforehand. Ron adds that Amamiya has been trying to prevent him from entering his room: After all, she suggested working their way upstairs investigating and persisted with her supernatural theories.
This prompts Mofu to confess that Ron's cat went missing this morning. Amamiya offered to stall Ron and Toto while she and Chicory went to search for the cat. Unfortunately, they were unable to locate it.
Smiling, Ron takes everyone upstairs and reveals that his cat often "runs away" to the roof. Everyone is glad to know that the cat is safe and well. Amamiya and Kawasemi get into an argument though because he saw the cat earlier and failed to inform them.[265]
Kamakura Teahouse Murder Case
In Kamakura, Ron, Totomaru, Chicory, and Kawasemi visit, i.a., the Tsurugaoka Hachiman shrine and the Great Buddha. Afterward, Kawasemi takes them to a shop where he picks up a pair of tweezers he commissioned from a Kamakura artisan, and because Ron spots Kamakuya Sweets nearby, they decide to take a snack break from sightseeing.
Though the teahouse is marked as "reserved" today, its employee Wataru Akizuki tells Ron and the others that the reservation was cancelled and they can come in. Then, one more customer and Hojo from a rival shop arrive. Hojo demands to speak to the manager as she believes he is stealing her sweets' designs. When Akizuki tells her that the manager is busy, Hojo leaves angry.
Sometime afterward, a scream is heard coming from the teahouse's main building. Ron and the others immediately immediately rush to the scene and discover the shop's owner dead in his office.[266] Toto and Kawasemi reveal themselves as police officers, and they and Ron proceed to examine the crime scene.
Judging from the room's state, the manager seems to have struggled against his killer. Further, the manager's hand is sticky and a piece of candy is in his mouth. Right before the local police arrive, Totomaru notices Hojo hiding in the bushes. Ron and the others then question everyone present.
Hojo states that she only just returned to "discreetly" look for evidence that the manager has been ripping off her designs. Toto doubts that she only "just" came back. The other customer Kei Moore testifies that he came to Kamakuya Sweets because he was looking for a café with sweets and was in the bathroom at the time of the crime. Ron and Kawasemi are suspicious of Kei for placing an unspecific order despite seeking out a sweets shop and for being unusually calm even though a murder happened.
Lastly, Ron and the others interrogate Akizuki. He tells them that the manager shut himself in his room after noon because he wanted to test and judge his newest sweets. During that time, the manager always wants to be alone. Afterward, they re-examine the crime scene which Ron notes to seem different than when they first saw it. They discover two firm, broken pieces of yokan in the two top drawers of the dresser which are, alongside the lowermost drawers, open. Oddly, the center of the blood spray on the sliding screen does not line up with the owner's wound.
When Chicory shows Ron, Toto, and Kawasemi a post Hojo made to compare her designs with Kamakuya's, Ron and Kawasemi solve the case simultaneously.[267]
Ron and the others then gather everyone to present their deductions: Akizuki killed the manager. He stabbed him beforehand and prepared the crime scene so that blood would splatter onto the screen while Akizuki was with the customers to give him an alibi. However, because Akizuki is the only suspect with an alibi and because Ron and Kawasemi noticed that he took the pouch used for his trick from the crime scene, they could figure out the mystery. Further, the manager put a "hydrangea" candy in his mouth as a dying message to refer to Akizuki: "Akizuki" is written with the same characters as "Meigetsu," a temple in Kamakura famous for its hydrangeas.
Akizuki confesses that he murdered the shop owner because he did not allow him to open a second branch, stating that he was not ready yet even though Akizuki thought he was. Akizuki is subsequently arrested.
Later that day, Ron and Toto say goodbye to Chicory and Kawasemi at the Kamakura Train Station. Ron then tells Totomaru that it is now time for a "nostalgic reunion"; a moment later, Kei appears and insults Ron for taking so long to remember him.[268] Because Toto is surprised that they know each other, Ron explains that Kei is Kiku's son; they also attended BLUE together.
Afterward, Ron asks Kei what he is doing in Japan because Kiku told him he was in India. Kei tells him and Toto that he was transferred to Japan two days ago to become the chief of the World Detective Alliance's Japanese branch. Further, the Alliance decided to postpone the practical exam for the reinstatement of Ron's detective license indefinitely because of his blood ties with the M. Family and the possibility that Alice Moriarty might be behind the Missing Detectives Case. Kei advises Ron to simply "resume [his] carefree lifestyle" because the "Anti-Alice" Team will catch Alice and his services are not needed. Although Ron was initially angry, he only calmly notes that he is "fed up" with the WDA's foolishness after Kei leaves, saying that he can live with it as long as he receives "special treatment."
Spitz then videocalls Ron and Toto from London on behalf of Alissa, Hatter, and Marsh as they want to speak with them. They inform Ron and Toto that Knight has stopped coming to school and their attempts to reach him failed. Knight has been down since the Cryptid Serial Murders Case because he could not catch Billie and he kept muttering that "Alice is coming."[269]
Target: World Detective Alliance Case
At the Maison du Kamonohashi, Toto reads that more employees of the World Detective Alliance were found murdered. Ron is sure that Alice is involved in their deaths which means that Knight was right: Alice has come. Toto wonders how Knight could even know that Billie was Alice; after all, he and Ron never told him or the other BLUE students that. Ron says Knight likely learned this from his father's documents as he is a vice-chairman of the Alliance.[270]
Sometime later, Ron calls Kei; he obtained his phone number from Kiku beforehand. Ron warns him that Alice has made her move and is now targeting members of the World Detective Alliance. He adds that the Alliance is only reaping what they have sown because they refused Ron's offer to help him even though he is the only one who could take Alice down. Totomaru scolds Ron for his words and states that Ron is actually worried about Kei. Kei tells them that he is busy and that they should come see him in two days.[271]
Right afterward, Kei notices that Alice sent him an invitation to a game of hide-and-seek.[272] He subsequently informs the Metropolitan Police Department about this, and Amamiya assigns Toto the responsibility of protecting Kei.
Ron and Toto then head to Kei's hotel room. When they cannot find him there, Ron phones Kei, and Kei tells him that he went to an amusement park to protect himself because he considers it a "safe" place as there are many people around.[273]

- Archery: He is rather skilled at archery, though he has not practiced it for over ten years. Ron is especially interested in "the mental aspect of it, and how it forces you to face yourself."[283]
Quotes[]
- "The culprit has blended into this group after causing chaos and fear... And is probably smirking underneath the mask of fear they're wearing... But... You're going to regret it. You've angered the one person you shouldn't have."[284]
Etymology[]
- Ron's surname "Kamonohashi" means "duck/wild duck, easy mark" (鴨, kamo), "from" (乃, no) and "bridge" (橋, hashi).
- "Kamonohashi" (鴨乃橋) also means "platypus" (鴨嘴 / かものはし) but is written in a different kanji.
- For the series' announcement, Akira Amano's official Twitter account posted a picture of a platypus with the manga's release date.[303] Ron also has a great fondness for platypuses.
Trivia[]
- Ron got interested in astronomy because his ancestor Sherlock Holmes did not know anything about the heliocentric theory or the solar system.[304]
- He is a terrible shot with a gun and received nothing but failing grades in his firearms class.[305]
- He can read very fast. For example, he read all of Takanori Aoe's academic papers in half a day.[306]
- When Ron was three years old, he was unable to say "brown sugar" properly. He pronounced it "bwown sugar" instead.[307]
- Ron can drive. He drives a car with the Union Jack on its roof.[308]
- He used to be obsessed with the Swiss-French architect Le Corbusier. He even said that if he ever built a vacation home, it would be in a country with a Le Corbusier building.[309]
- When he was younger, Ron often went to Obon dances.[310]
- He likes difficult cases and kuromitsu, and dislikes free time.[11]
Out of Universe[]
- In the Shōnen Jump+ and MangaPlus online version of Chapter 3, his surname is mispelled as "Kamonohash" in his BLUE registration file. This mistake was corrected when it was re-released in tanbōkon format. The re-release also changed the "Expulsion" stamp from Japanese to English.[311]

- ↑ Ron was six (Chapter 41, page 17) when his parent died 17 years ago. (Chapter 44, page 5) This means that Ron is about 23 years old.
- ↑ Ron was 17 when the Bloody Field Trip Case happened five years ago. As the incident happened in October, (Chapter 73, page 16) and his birthday is in December, he would have turned 18 later that year. The Tragic Cruise Serial Murders Case happened in late October, and fully concludes two months later. (Chapter 95, page 8) Ron's birthday already passed by then, meaning he should be 23 now.
- ↑ The birth order of Teo and Eli is unknown so far.
