My Desertion Would Be Faster Than Heros' Obsession - Chapter 9Vol 2.

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.

The Saint: “My sister is very beautiful”

Yi Feng (His eyes is glowing): Little Saint, you can follow me from now. All right, remember to tell your sister to come!

The King: “Yi Feng! Your bastard, what are you doing?

Yi Feng: My bad! My bad! My king, I just want to stroll in this harem a little bit. Who knows those girls have been following me like that?
