In the middle of a deserted island, a small boy wakes up with two sets of memories: one from his few years of life and the other from a man who lived to adulthood and achieved great things. When he least expected it, a powerful master appeared on the island and took him in as a disciple, revealing a shocking fact: magic exists in that world, and, thanks to it, humanity managed to conquer the galaxy.

The human race is fending off the assault of the thaids, strange monsters evolved by animals occupying most of the earth's surface.

Because of the monsters, society has evolved into one based on individual fighting prowess; Erik is an abandoned young boy living in such society with the most useless of the powers.

Everything changes when his father returns home, bringing something he would have never expected.
