==Biography==
===Ron Kamonohashi's Homecoming Case===
Hatter hears Alissa Beaumont, Udy Dietner, and Marsh Leipley speculate about the arriving newcomers. When Udy suggests that they might be new instructors, Hatter agrees, pointing out that Aimee Emmerich said she needed new ones. He remarks the new people might be Chinese, not Japanese as Udy guessed, not knowing that she made her deduction based on the fact that Totomaru Isshiki is carrying a bag from Asakusa.
He later attends Totomaru's first lecture; though he stares at Toto throughout the lecture, Hatter pays little attention to it. Afterward, Hatter watches Toto solve the mystery of Alissa's "murder" as well as save Alissa from falling off the window ledge. While Toto's actions win Udy, Marsh, and Billie Za Gozzila over, Hatter still thinks he is a "loser" and, thus, cannot understand why they are fawning over him.
The next day, Hatter heads to BLUE to talk to Aimee about his academic advancement plan. However, when he finds her collapsed at the table in her office, he runs to get help, waving at the arriving Totomaru, Ron Kamonohashi, Billie, Alissa, Udy, Marsh, and Knight Bran Jr. in panic. Immediately, everyone rushes to Aimee's office and discovers that Aimee was shot and a strange video is playing on her laptop.
===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 Toto and Ron 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, and Alissa asked Marsh, Udy, and Billie to assist her. 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 the students, Ron, and Toto.
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. Toto and Ron rush outside to check the bridge, but it was already drawn and because only Aimee knew the isolation system's deactivation code, they are now trapped in the school.
Later, everyone gathers in a lecture hall to discuss why they might have been isolated at BLUE and how to proceed. While Ron and Toto check Aimee's laptop, the students separate and wander alone through the school. Hearing a scream, Hatter runs to the courtyard and sees Udy's corpse. Her lifeless body bears deep gashes, and a piece of paper saying "Chapter 1: The messenger from the sky Wyvern" is next to her. Curiously, only her footprints are visible, and Udy's body lies in the middle of the courtyard.
Ron then notices that Billie is not there. Marsh speculates that she might be in the hidden room under the north building as she once told him 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.
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.
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. She learned about it from a special "Unsolved Mysteries" class; apparently, that book was left at several crime scenes connected to the M. Family.
While Totomaru and Ron re-examine the crime scene and search the building, the guard and the other students go to the home economics room to make dinner. Hatter, however, heads to their classroom to get the food he was hoarding there. He arrives in the home economics room right after Ron and Toto, and 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 John 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.
Hatter goes to a basement room where Totomaru eventually finds him. Although he expected to find Chelsea, Totomaru takes this opportunity to tell Hatter what truly happened in the Island Observatory Murder Case. When he adds that Grizzly—who investigated without bias and apologized upon realizing that Ron is not the culprit—would be disappointed in him because of his attitude, Hatter becomes angry and grabs Toto's shirt. Totomaru says he can go ahead and hit him, though Grizzly would be mad at him if he could not protect Hatter when he is half-dead. His words knock sense into Hatter. Minigozzi then finds them.
Toto and Hatter meet Ron and Knight upstairs, and the monkey guides them all to the locker room. There, they find a locker leaking water. Hatter quickly picks the lock, and they manage to rescue Billie on time who was tied up and placed in the water-filled locker. A cover page 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.
Hatter and the others hurry to the rooftop where they find Chelsea's corpse; Hatter is devastated when he sees her body. 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 decide to split up: While Marsh and Alissa bring Billie to their classroom so that she can change her clothes, Toto and Ron as well as Hatter, Knight, and the guard will investigate the area. They also agree to meet up again in an hour.
Hatter, Knight and the guard examine the ground and find nothing. He notes that Knight looks "kinda excited." Knight explains that his brain is "stimulated by this impregnable mystery" which he is determined to solve.
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 destroyed. Ron and Toto found marks on a pole as well as a bloody body bag on the roof. Afterward, they examine the third crime scene, and Billie tells them that she went looking for her pet rabbit and cat earlier. 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 Toto and Ron away to the rooftop; Toto tells the rest to wait in the dining hall. When they later go there, Hatter and Marsh tell them that Alissa wanted to consult with Totomaru and followed him, Knight, and Ron to the roof. Billie accompanied her, and they have not yet returned.
Shortly afterward, Ron tells Hatter, Marsh, 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. Hatter and the others then search for him, Alissa, and Billie.
After Hatter tells Totomaru and Ron that Billie liked to go to the monument room, Ron realizes that Billie is specifically targetting BLUE's best students. They go to the courtyard and find the secret entrance under Udy's body. The guard stays behind while the others go down, in case something happens. By the time, Hatter, Toto, Ron, and Marsh find Alissa and Knight, Billie has drawn a significant amount of blood from them, but has not killed them yet.
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 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: To test Toto's reflexes, she has set up crossbows that will shoot arrows at the unconscious Knight and Alissa in a moment. Marsh and Totomaru can save them on time though.
Afterward, Billie flees. However, Hatter spots smoke drifting outside through an air vent and knows where she would go. He and Totomaru can catch her on time and arrest her. The police subsequently take Billie away, and Hatter is presumably sent to the hospital with the other remaining students.
Two days later, Hatter, Knight, Alissa, and Marsh are back at BLUE. Just when they talk about how Ron and Totomaru would return to Japan today and that they wish to bid them goodbye, Totomaru and Ron arrive at the school. Excited, they meet up outside the building.
They chat briefly, and after Ron tells the students to take care of BLUE, they part ways. Class begins shortly afterward, and when Hatter and the others begin texting Toto while ignoring their new instructor, he becomes upset and heads back to BLUE to "set them straight."
===Kamakura Teahouse Murder Case===
After Ron and Toto have returned to Japan, Spitz videocalls them from London on behalf of Hatter, Marsh, and Alissa as they want to speak with them. They inform Toto and Ron 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."
