|Japanese name:||来須 圭悟|
Calm, cool and collected, Keigo does not show any interest in wanting to win the game. Unlike the other players, his participation is an effort to stop the murders that will occur if it continues. He makes an effort to recruit some of the other diary holders into his cause, but his main goal is to capture the ones too dangerous to be left roaming free. He was chosen by Deus to balance out the criminals and maniacs that are also taking part in the game.
