Karate Shoukoushi Kohinata Minoru

A college student at an institution known for athletics rather than academics, Minoru initially trains in gymnastics with his friend Nana but 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.
