Mitsumine High School has a reputation as the institution with the highest number of juvenile delinquents in the country. The students are so violent that even the teachers fear for their lives. Sunahara serves as the leader of the first-year students and is the toughest guy in his class. However, when transfer student Asagiri Shinnosuke arrives at the school, he begins taking down names and kicking up dust like a tornado. If the students believed things were violent and unpredictable at Mitsumine, they haven’t seen anything yet, since Asagiri is here to become the school champion.
