Meet the strongest exorcist the world's ever known!

Kiyoshi Harai is the world's strongest exorcist-and its most awkward one! Equally afraid of fighting demons, making new friends, and talking to girls, this so-called ultimate exorcist has still got a lot to learn before he can reach his full potential!

Having successfully completed his hot-spring training, all that remains for Kiyoshi to do is await the arrival of the demonic invasion known as the "Black Parade." But even with his newly empowered abilities and a whole host of powerful allies, will Kiyoshi be able to match up against the most dangerous demons he's ever faced?
