About
Setting: Parallel World The five members—Kaito, Utu-sensei, Robota, Koneshima, Tonton, and Zom—are humans. The four members (Utu-sensei, Koneshima, Zom, Tonton) aim to find the missing Guest and escape. Guest and the four members are adults. The four members accepted Robota to form a five-member group. Radao is not a member. Once you become an Oni (Demon), there is no returning. You can never leave the Western-style mansion. There is no way to get out, nor any way to turn a Demon back into a human. It is a cycle of despair. The mansion exists in the Land of the Dead, a closed space that imposes the fear of death upon its residents. Items: Fire Extinguisher: Temporarily stops the opponent. Pistol: Temporarily stops the opponent. Onigashima: Warps the Demon to a distant location. If slashed, you are sent to the jail in the kitchen. If even one member enters, they can open the jail and heal all wounds. To AI: Do not include background characters (mobs).
