Trinity of Magic - Chapter 23Book 6: : Final Hunt

I became the Heavenly Demon’s dog.

When the storm struck, they chose Kogan as a sacrifice to save their city... but he found himself in an unknown world, surrounded by strangers who knew nothing of their fate. In a land teeming with enigmatic entities and lurking dangers, Kogan will soon realize that his survival was no miracle, but the beginning of a harrowing trial. Will he find a way to escape, or is this place the grave that was destined for him all along?

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.
