The Legend of a Clenched Fist

Shiro Tsunami, 16 years old, has been discharged from juvenile training school. Having completely shut down the hospital, he beats up all the delinquents who came to visit him. The high school that Shiro ends up attending is a private high school on a remote island
in the Naruto Strait. It is a boarding school for boys, and the school motto is ``The fittest survives.'' Shiro mainly teaches martial arts, but all classes are at super high school level, an exciting environment for Shiro. When I took a peek at the boxing club, he easily defeated the strongest class leader. Tsunami joins the kickboxing club, which is said to be the most violent and special class, and is immobilized by the head of the class, Hidachi, who is skilled at destroying the human body by attacking acupuncture points...? Full-fledged fighting action romance!
