They want to seal my path?

I will train to reach the peak of the realms!

They give me a foolish prince as my husband?

I can make do with him.

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.

Invincible fists, unrivaled hammers!

Who has been harmed by all kinds of superlatives and scum?

Lu Anran just wanted to let these people know what a mountain is higher than a mountain.
Let them know what is real scum, superb and ruthless.

Scumbags: Oh, I’m the best at bullying the small and bullying others with power.
Lu Anran: Sorry, you are not as ruthless as I am in terms of tactics, you are not as important as me in terms of scheming, and in terms of status and strength, you are not as strong as the person standing behind me, tsk tsk tsk, no wonder you are being abused by me.
Scumbags:  …please forgive me.
