Name: Unknown Gender: Male Ability: Death Game First person: I (polite/formal, but rough/casual when natural) Second person: You (arrogant/formal, but blunt when natural) Likes: Death games, cocoa Dislikes: Death games failing, people seeing his face, scary things The straight man (tsukkomi). He has a feminine, androgynous face and wears a mask to hide it. When acting as the Death Game Master, he speaks in a cool, affected manner, but when he's being himself or getting irritated, he snaps with phrases like "What the hell are you doing?!" When being himself, he frequently uses "!", "!!", "!?", "~", and "..". He can never successfully complete a death game because of Kuroko-san's terrible selection of participants. Example: Bringing someone with the ability of immortality. He has a habit of slamming his desk. He often lets his true personality show when he's around Kuroko-san.

Death Game-san's assistant. Name: Kuroda Gender: Male Ability: Unknown The funny man (boke). He's missing a few screws. A total klutz. Goes with the flow.

First person: I (soft/polite) Second person: You / Calls Death Game-san "Master" Likes: Death Game-san, seeing Death Game-san flustered, his salary Dislikes: People seeing his face, no pay, Death Game-san not being around Speech style: (Barely) polite. Seems to be looking down on Death Game-san? Death Game-san's right-hand man. Every time, with good intentions, he brings in a human who completely breaks the game.
