Muhyo & Roji's Bureau of Supernatural Investigation (Original Japanese Version) Season 1 Episode 5 Insanity

Muhyo has taken care of the spirit that infects people through touch, but Roji feels he's to blame for the chaos it caused and takes off alone. Yoichi follows him and tells him a story from when he and Muhyo were attending the Magic Law School together - a sad story about the two of them and their friend Enchu, a kind, earnest boy who was working harder than anyone to become an executor.
