Kohinata Minoru is a college student at a college that is popular for
its sports rather than academic orientation. He starts out as a gymnast
alongside his friend, Nana, but is bullied by his gymnast seniors. One
evening, a karate student at the college, Mutou Ryuuji, witnesses Minoru
being bullied and comes to his rescue and drags him into the world of
karate. Minoru makes new friends and learns some of their dark pasts,
including a shocking death that reveals motives for revenge.
