- Description from Novelupdates

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.

Yuder was a commoner Omega who rose to the top with his ability.

When he woke up again after being falsely accused and executed, he was back 11 years ago before everything began.

A chance to get back……

He must not repeat the same mistake he did before.

To survive, and to save the world, now he had to save the man he had killed!
