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.

That year, the basketball god retired forever.

That year, the four giants of the City of Angels, which shocked the world, came to the fore.

That year, the little emperor entered the hometown team with unparalleled talent.

…

That year, the son of planes, the great magician, the corrector of order… plunged into this era when the opponent was like a wolf like a tiger.

Come, come, stand in line one by one… How am I going to carry out this delightful torture (× crossed out)

My dream is just to heal your wounded hearts, yes, this is a homophonic stalk. – Liu Xiu.
