Trickster

In the year 203X, a security robot goes on a rampage in Shibuya. Nakamura Nao, a police detective, commissions detective Akechi Kogorou to solve the case, but Akechi, along with Inoue Ryou, is already heading toward the robot's manufacturer.

A young woman approaches the Boy Detectives' Club and asks them to find the intended recipient of a series of threat letters her boyfriend made. They accept the job and begin to tail her boyfriend.

Kobayashi somehow feels that maybe he can die if he stays with Hanasaki, so he joins the Boy Detectives' Club. His first mission is to help find a jobless young man who's gone missing.

After school, Inoue watches Katsuta's tennis club practice before heading home, and Hanasaki tests out some tools of the Boy Detectives' Club trade. Meanwhile, a police car is found overturned after a crash.

Kobayashi and Inoue are trapped in the underground channels as a result of Twenty Faces' maneuvering. Worried about the officers searching elsewhere in the channels, Inoue tells Kobayashi to escape and warn them that the map they were given is fake.

Hanasaki has been trying to help Kobayashi die, but nothing has worked. While Akechi is away, Hanasaki takes the liberty of accepting six job requests.

Akechi is relaxing at a spa to relieve the exhaustion of his recent cases. Nakamura asks him about his history with Twenty Faces, and Akechi begins to recount the trauma of his youth.

The residents of the Kokorogaoka Housing Complex refuse to vacate their homes for the sake of urban development, so they declare its independence from Japan as an autonomous borough. The one to make this announcement is none other than Hanasaki's brother.

Isuzu is negotiating with the police for three billion yen in exchange for the removal of the residents of the housing complex. Nakamura requests the aid of Akechi and the Boy Detectives' Club in the case.

Hanasaki runs out of the office after an argument with Akechi and the others, only to end up confined by Twenty Faces and shown several video clips that cut deeply into Hanasaki's psyche.

Hanasaki's act is successful in convincing Akechi and the Boy Detectives' Club that he was kidnapped by Twenty Faces. Akechi takes off to try to save him, saying he has an idea where Hanasaki might be.

Even with a gun pointed at him, Hanasaki is brought to tears by the conversation between Twenty Faces and Akechi. Then the Boy Detectives' Club arrives on the scene.
