Description & Story

Keisuke and several others suddenly find themselves in an unfamiliar white room. They’re all still confused when a voice suddenly tells them that the game is ready to begin. The voice tells them that Keisuke is to be the “unlocker”. He has to pick a girl every so often and perform a special deed on her in order to open the lock.

One of his classmates, Miyako, refuses to accept the terms of this “game” and protests. Without further ado, she’s chained and tortured to death. The horrific scene played out in front of everyone else present, but Keisuke found himself aroused instead. Did someone notice?

Trapped in a horrible game, what will now happen to all of them?
