Rei Genma is a street illusionist with no real magic, only tricks. His talent for faking magic is so great it fools even the powerful mage Enshin Yosuke, who invites him to the biggest exorcist tournament.

The prize? A potion capable of curing any disease , the only hope of saving his dying mother.

But in the middle of the tournament, a demonic ritual wipes out all human magic. Everyone becomes powerless… Except the man who never had any power in the first place.

With only his mind and his illusions, Rei must face demons and monsters that still wield their full power.

In a place of fallen legends, can a fake hero become the only real hope?
