Yukina Fukushima

Chisato and Mahiro are two high school girls who are about to graduate. They also happen to both be highly skilled assassins. When the organization they work for orders them to share a room, the relationship between the pair quickly turns sour. However, when they find themselves targeted by the yakuza, the girls quickly realise that they will have to find a way to work together.

With his two friends, a video-game-obsessed young man finds himself in a strange version of Tokyo where they must compete in dangerous games to win.
