Dragons Rioting

At six years old, Henisei is diagnosed with Hentai Syndrome, a condition that could kill him if he becomes sexually aroused. To help him control his body and avoid that danger, his father trains him in the mountains for ten years. At sixteen, Henisei enrolls at Nangokuren High School, believing it is an all-boys school. He soon discovers that it is actually an all-girls school that has only recently become coeducational.
