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.
