Nobody talks about this one. Shuramaru spends the entire show trying to convince himself he's human while the village he's trying to protect makes it clear they will never believe it. That contradiction, wanting to belong to people who have already decided what you are, is the real horror, not the supernatural stuff.

Shuramaru lives among villagers who fear and despise him because of the strange powers he possesses. Despite how they treat him, he considers himself an ordinary human being, though whether that belief is true remains an open question. Fighting Devil Divinity Oni is a 25-episode supernatural TV anime from 1995 built around the mystery of what Shuramaru really is.
