A timid student named Fumio Kijima meets a girl who calls herself a demon. She claims to be a campaign girl from the demon world and bestows upon him the ability to "summon a room" out of thin air. Initially, he refrains from exploiting this power, using it only as a convenient tool in his everyday life. But one day, his classmates bully him under false pretenses, causing him intense suffering. In the past, he would have wallowed in misery and cried himself to sleep, but now he has a power he can rely on. "I will make them regret it!" Using his ability to summon his "room," he begins his era of confinement and brainwashing to achieve his goals.
