As a six year old, Rintaro is diagnosed with Henisei Tashu Ijou Syndrome
(also known as Hentai Syndrome), a disease that could kill him if he
gets sexually aroused. To save him and provide a way for him to live as
normal a life as possible, his father teaches him the ways to control
his body and mind for ten years in the mountains, with the martial art
of the Koei Sougetsu. When he's 16 he chooses to enroll Nangokuren High
School, which he assumed to be the biggest all-boys school in the
country but is actually the biggest all-girls school that has just gone
coed.
On his first day he stumbles upon a large scale battle and
learns that the first rule of the school is that it "Abides the Law of
Nature" which has turned the campus into a war zone-like environment.
Rintaro now sees transferring out as his mission, but will it be that
easy now that he's caught the eye of the 3 "Dragons", the bodacious
female leaders of the three biggest factions around?
