Owari no Chronicle - Volume 14, Chapter 23: Our Reason

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.

Rejected, due to being an human in the land of elves, Kevin was banished and casted into the river the very day he was born. But fate said he would live as he was rescued by the very person who casted him into the river.

Every mage when they reach the age sixteen were told to attend the mage academy and Kevin, the abandoned human who had overheard the conversation of some students, got excited to attend this academy.

He asked from his guardian if he could attend the academy but unfortunately, he was denied, all because of him being an human and not an Elf. At that moment, he became angry and had locked himself up in his guardian’s workshop, that was a room full of all types of magical items.

But while in the room, Kevin had spotted a golden ring that instantly glowed as soon as it touched his bloody fingers. Surprisingly, he was given a system that granted him the opportunity to be an Elf. But what he discovered was that, he wasn’t just an elf but a fairy and also an human.
