Kemono Jihen

is a Japanese manga series written and illustrated by AIMOTO Shou. It is serialized in Jump SQ.

Plot
When a series of animal bodies that rot away after a single night begin appearing in a remote mountain village, Inugami, a detective from Tokyo who specializes in the occult, is called to investigate.

While working the case, he befriends a strange boy who works in the field every day instead of going to school. Shunned by his peers and nicknamed "Dorotabo" after a yokai that lives in the mud, he helps Inugami uncover the truth behind the killings - but supernatural forces are at work, and while Dorotabo is just a nickname, it might not be the only thing about the boy that isn't human.
