Kohinata Minoru is a college student at ,Reinan University, which is popular for its sports rather than academic orientation. He starts out as a gymnast alongside his friend, Misaki Nana, but is bullied by his gymnast seniors. One evening, a karate student at Reinan, Mutou Ryuuji, witnesses Minoru being bullied and comes to his rescue. Then Mutou attempts to change Minoru's passive behavior by dragging him into the world of karate. Minoru, joining the second karate club (Kaburagi-ryu karate), makes new friends and learns some of their dark pasts, including a shocking death that reveals motives for revenge.
Passive behavior at first. After being taken in by the 2nd Karate club, Minoru changes from an athlete to a fighter. Normally still passive, but once someone mocks/beats his friends his behavior changes from passive to agressive and shows that he is ready to brawl. It can be said that he has been infected with Mutou's poision as Kohinata loves to fight as a way to improve his self. But he doesn't go around starting random fights as we first saw Mutou doing. Sometimes Minoru's aggressive behavior can become his achilles heel in some cases, as he may tend to not listen to fight plans and start fights with fighters stronger than him.
One day at the gymnastics hall, minoru got beat up by the gymastics members. His friend Nana tried to help him, but instead she got pinned down. That's when the mysterious masked man appears. He couldn't stand watching minoru being so weak, and drags him off to the karate club.
