LatestHanasaki left Kobayashi behind and took off for Twenty Faces' hideout alone, planning to put an end to everything; Kobayashi can't accept that, so he follows him even though the aura surrounding him has already disappeared.
It is the 2030s. The Boy Detectives Club gathers under Kogorō Akechi, the mysterious detective. The group solves cases great and small using their unique skills. One day, a member of the club, Kensuke Hanazaki, meets the boy Yoshio Kobayashi. Kobayashi's body cannot die due to the effects of the "Unidentifiable Mist," but he yearns for death, and shirks from contact with other people. Taking an interest in him, Hanazaki invites him to join the Boy Detectives Club. Their meeting is connected to the fate tying together Kogorō Akechi, and the era's greatest villain, the Fiend With Twenty Faces.
Acting
GACKT's theatrical villainy steals every scene he's in
Production
Art deco futurism that screams 'we had a budget for backgrounds'
Writing
Rampo adaptations that get weird in the best ways
Trivia, insights & behind the scenes
Edogawa Rampo's Boy Detectives Club stories from 1930s Japan get a cyberpunk-adjacent facelift here, with Akechi and Twenty Faces as established cultural icons like Holmes and Moriarty.
GACKT specifically requested the Twenty Faces role after reading the source material; his performance was recorded before other cast members to set the villain's theatrical tone.
