A chilling air swept across the desert as a figure in a black cloak and obsidian crown walked toward the advancing army of House Elyria.With a raise of his hand, the sun turned black, plunging the battlefield into darkness. The wind ripped away the sand, revealing an ocean of skulls, and from it, thousands of undead surged, surrounding the army.Blood spilled, and with each death, the army grew—undead rising even before their bodies hit the ground. The figure stepped onto the shoulder of a massive giant, its molten eyes burning as it crushed entire squads with a single swing.As the black sun set, only the general remained.

- Description from novelbuddy

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.

Going for a swim, she ends up in an ancient wild Beast World and ends up being brought home by a handsome wolf.
