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!

The Black Parade rages as demons and exorcists clash in a brutal fight for the souls of everyone in Naraku City—and with a terrible toxin transforming Kiyoshi back into a toddler, things are looking more dire than ever! Now the world’s strongest baby and his rival must team up and find a way to get Kiyoshi back to normal while the Thirteen Club’s strongest members prepare to finally take action.
