Twelve years ago, an old beggar found an abandoned baby and took him as his own son, naming him Xu Han. But when his foster father dies, Xu Han finds himself in a training camp with dozens of other kids, though what they’re training for remains a mystery. It’s here that he meets his best friend, Liu Sheng, and life is good for a while — regular hot meals and a safe place to stay. But kids keep being taken and not coming back, and eventually, Xu Han and Liu Sheng find themselves left in the woods at night, where they discover what’s happened to the kids who disappeared before them — they’ve been turned into zombies! Can the pair destroy the zombies and survive the night, or will they be the newest victims of this twisted conspiracy?

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.
