狼ゲーム

12 people are all gathered together inside of a mysterious building, who are then forced to play the "Wolf Game".

Each person must draw a card. One person draws the wolf card, and must kill another player. Everyone else draws a sheep card, and must find out who the wolf is in a trial. If the wolf is found out, they are then executed.

To escape from the building, the players must find every wolf - and in the process, discover the truth to this game.
