The manga’s story centers: A victim of unending tormenting, Aito Eyama is tormented by his colleagues’ consistent insults and beatings. Be that as it may, through a random new development, he gets an odd solicitation for the “Imprisonment Game,” where triumph guarantees fantastic riches. To partake, he should acknowledge the job of captor and pick one unfortunate casualty to detain for a month. For Eyama, the main decision is Aya Kirishima, the instigator of his harassers and the wellspring of all his anguish. The standards of the amusement are basic: the prison guard may do whatever they please with their prisoner notwithstanding murder; yet so as to win, the captor’s personality must stay covered up. Exception from the law, a disengaged cell, and the assets to buy supplies—all the essential instruments are given.
