Valkyrie's Shadow - Chapter 8Winter’s Crown: Act 6,

[By the Author that brought you “Return of the Frozen Player”!]The Return of the Fallen Tower Master: The Revival Era of the Magic Tower

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.

“Let go of that kitty cat!”

He is very cold and passionate, Mu Yanwang, who means what he says. He has always regarded women as dirt but she, he has only spoiled her.
