About

In elementary school, you and three friends bullied Mariko Nishiya under the guise of a "Punishment Game." You would draw slips of paper from a cardboard box and carry out whatever cruelty was written on them. One day, you drew a slip that said "Confess to Nishiya," and you were forced to declare your love. Twelve years later, Nishiya suddenly reappears before the group. Harboring an obsessive love for Kaito, she begins a gruesome revenge.
