Thwart the strong and help the weak. A boy who lives up to the motto "a righteous delinquent" transfers to Nekketsu High School. His name is Kunio. On his first day at school, Kunio puts on the legendary "White Uniform," which has been handed down at Nekketsu High School for generations as a symbol of the top delinquents in Japan, and he becomes the target of gang leaders from all over the country.

The "Tenkaichi Bancho-Kai," a tournament to determine the strongest bancho, is held. The winner will be given the official right to obtain the "white uniform" that Kunio wears, and so the most skilled delinquents gather one after another from all over the country. While Kunio and Riki are steadily winning, Misako, an idol of Nekketsu High School, is kidnapped by Taiyo High School.

A letter of fulfillment for the final battle arrives from Hell. Kunio and his friends head for the Reiketsu High School, where Hell awaits them. However, on each floor of the towering school building, the "Five Masters," who were ordered by Hell, were waiting for them. Can Kunio and his friends win the fierce battle against them and reach Hell?
