A ongoing martial arts/comedy manga also known as Dragons Raiden
by Watanabe Tsuyoshi debuting in 2012.
As a 6 Year Old, Rintaro is diagnosed with Henisei Tashu Ijou Syndrome (translated as Odd Behavior Towards Opposite Sex-Syndrome) also known as Hentai Syndrome, a disease that could kill him if he gets too sexually aroused. To save him and provide a way for him to live as normal a life as possible, his father teaches him in the mountains for ten years the martial art of Koei Sougetsu
as a way to control his body and mind when confronted by females. 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 recently gone coed but is still now 99% female.
Rintaro now sees transferring out as his mission, but 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 between the strongest fighters. Forced by circumstances to demonstrate his skills, he's caught the eye of the 3 "Dragons", the bodacious female leaders of the three biggest factions that struggle against one another control the school. In particular, Ayane, the first year leader is determined to make him her 'master' after seeing him perform martial arts.

- Muscles Are Meaningless:
- While hailed as being the most powerful and being larger than the other two Dragons, Kyouka looks more like a model and does not have the physique that leans to punching a six-foot man eight feet into the air. Rintaro, on the other hand, is sufficiently ripped due to years of training under his father.
- The skinny old man principal who threw the insanely heavy dice that cracked the floor.
- Rintaro lampshades this by comparing Kyoka to a Saiyan when she does insane acts of strength.
- Oh, Crap: Played for Laughs, whenever Rintaro is exposed to fanservice.
