Karate Shoukoushi Kohinata Minoru

Minoru is a college student at an institution better known for its athletics than its academics. Initially training in gymnastics with his friend Nana, he faces bullying from more experienced gymnasts. One night, a karate student named Ryuuji Mutou sees Minoru being harassed and intervenes, though not to protect him but to recruit him into karate. Through this, Minoru meets new companions and gradually uncovers aspects of their troubled histories, including a death that ties into a desire for vengeance.
