The Teen Exorcist, Vol. 2 (manga) — Mitsuru Yuki

Strange demons are appearing across the land…Now that Guren has come to his aid, Masahiro is ready to take down this dastardly demon and save the princess! But what awaits them beyond the battle is an even deadlier foe…one that has the head of a turtle, the body of a rat, and the cry of a dog. With no chance to catch his breath, it’s out of the frying pan into the fire. Still, he can’t give up now—not until he becomes even more famous than his grandfather, the legendary Abe no Seimei!
