Betrayed by his friends, Urea is banished and sent to live in the "Twilight World" where only demons dwell. Two years have passed since then, and Urea has struggled through and survived the Twilight World, while acquiring its power. Thus, the "jack of all trades and master of none" has become humanity's strongest sorcerer. Urea returns to the human world where he enrolls in elite training at the "School of Exorcism", is quickly selected to go from average rank to S-rank, and breezes through his rivals with his "phantom illusion" and "materialization" powers.
