In modern Japan, magic and yōkai exist, hidden from the public eye.

Rei Genma is a street illusionist with no real powers , 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, something goes wrong.

A demonic ritual wipes out all human magic. In an instant, spells flicker out, and the world's greatest sorcerers are left defenseless.

The only one still able to act… is the man who never had any power in the first place.

Armed with nothing but his mind and his illusions, Rei must face demons, monsters, and other creatures who still wield their full power.

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