Shouten! Mononoke Mura!!

Yagyuu Amami (pseudonym) is a rounin who makes a living by doing phony monster-exorcisms. Wearing priest’s robes stolen from a temple and a sword at his waist,
he travels from village to village tricking country folk and squeezing out enough coins to get by.

One day in a post town, broke and out of options, Amami takes on an exorcism request but what he found there… were actual youkai.
