Doubt

Rabbit Doubt is a popular game in Japan in which players act as rabbits trying to uncover a wolf hiding among them. Each round, the wolf kills a rabbit, and the remaining players work to identify the impostor. Sometimes, the players meet in person, and Yuu, Mitsuki, Rei, Hajime, Eiji, and Haruka gather to play. But one of them has taken on the role of the wolf for real and has already killed. The group must discover who is responsible and stop them before everyone meets a terrible end.
