王様ゲーム

Nobuaki Kanazawa and his whole class receive a text message signed only by "the King," carrying a command that has to be obeyed within twenty-four hours. Nobody can opt out, and the orders grow crueler with each round until failing to obey means death. As the class thins and the messages keep coming, Nobuaki tries to work out who the King is before the game runs through everyone he knows. This manga adapts Nobuaki Kanazawa's cell-phone horror novel.
