Aito gets what every bullied person fantasizes about: actual power over the person who destroyed him. The game doesn't let him feel good about it. What starts as revenge becomes a month of watching another human being break down in a cell, and Aito realizes too late that inflicting the same suffering he endured doesn't erase his own. The show earns its tragedy by refusing to pretend that justice and cruelty are different things.
A bullied student receives a strange offer: join the Captivity Game, where he may imprison his tormentor for a month with no legal consequences. Aito Eyama endures constant taunts and beatings from his classmates, so when an invitation arrives promising enormous wealth, he takes it. His target is Aya Kirishima, the ringleader of his bullies. The game's rules are simple. Eyama can do anything short of killing Aya, but he must keep his identity hidden to win, and he is given an isolated cell and money for supplies. As he carries out his sadistic revenge, he crosses paths with other captors who have their own secret aims. Aya, meanwhile, refuses to submit and will do whatever it takes to escape, and her efforts threaten to wake a buried darkness inside Eyama. A horror story built on psychological tension between captor and captive.
