Toru (Toru Nakamura) and Hiroshi (Kojiro Shimizu), two delinquent dropouts attending Aito High School, are still spending their days fighting with delinquents from other schools. One day, while they are brawling with delinquents from Joto Technical High School in front of the train station, Kyoko (Miho Nakayama), who was supposed to have transferred to a girls' high school far away, appears from the ticket gate. To their surprise, Kyoko has returned to Aito High School! Overjoyed, the two of them defeat the Joto delinquents with that momentum. From the next day, they are in the same class as Kyoko, and they are captivated by her during the lessons, but their rivalry over Kyoko only deepens.
