Otokojuku is a private boys school where true men are made. First year students quickly indoctrinated into the school's idea of what it takes to be a real man by Drill Master Onihige's constant berating. Momotaro, proficient in both academics and martial arts becomes friends with an underachieving weakling named Hidemaro. Together, they survive their Otokojuku days and become close with their classmates. Omito Date, former leader of the first-year students, plans his revenge against his former school. He is now leader of an evil army from rival Kanto Gogakuren school and fully intends on taking over Otokojuku. The Otokojuku principle, Heihachi Edajima, will not allow personal vendettas on school grounds, so the battle has to be taken elsewhere.
