Charge! Men's Private School

he First Years engage in a Forward Marching exercise that takes them through local people's homes and the headquarters of the Pure Evil Group, a local criminal gang which Momotaro overcomes. The group's leader Gokukoji Genzo, sends his son, Hidemaro to seek vengeance on the school and Momotaro. Momotaro defeats their champion and Hidemaro swears to take revenge for his humiliation.

The Otokojuku instructors put the students on a strict, and very unpopular diet so two students decide to raid the kitchen. The Instructors are also concerned about the students forming a union. Momotaro takes the blame for the kitchen raid and is put in the Prison of Penitence. Just as Momotaro's punishment is finished, the Pure Evil Group attacks the school. Togashi Gengi volunteers to take Momotaro's place in the Oil Bath of Hell to appease them and suffers a great deal. He does this in return for Momotaro's help earlier. As Hidemaro and the Pure Evil Group leave they are met by uncle Bro Yasha the Assassin assigned to take revenge. Momotaro beats him, and Yasha suggests that Hidemaro join the Otokojuku to develop his manhood.

Instructor Oni-Hige is seen of harassing a woman in the Roppongi district, and is beaten up by George, her huge American boyfriend. For revenge, Oni-Hige then sends the students on a purifying mission in the Roppongi district against dominating foreign men. They find the huge American in a discotheque, but the students find excuses not to fight him, and Oni-Hige is beaten up again. The next day, instructor Rankiryuu orders Hidemaro Genzo who is now a student, to purchase make-up in Roppongi. Meanwhile, the students are punished by having to hold a handstand position for an hour. Hidemaro sees the Americans scamming a local shop assistant and confronts the former WBB heavyweight boxing champion J.J. George but is easily beaten up. The students decide to take revenge, and using a combination of karate and kenpo, Momotaro beats him up. When Yoko, George's Japanese girlfriend, abandons him and approaches Momotaro, he rejects her for being fickle. Note: When Togashi is instructed to translate Japanese in the discotheque, he just shouts some common English phrases that he knows.

Togashi, Tazawa, Matsuo and Hidemaro decide to test Principal Edajima's skills, but mistakenly attack Oni-Hige instead. For punishment Togashi must do the Boulder Bunny Hop. Oni-Hige takes Tazawa, Matsuo and Hidemaro to Rakkyo University where he accuses the students of pursuing pleasure and fashion. He then suggests that they buy and wear traditional loincloths with Otokojuku logos. When they laugh at him, he orders his students to beat them into submission. They are stopped by the manly Rakkyo University Cheer Squad and held hostage for a 1 million Yen ransom. Principal Edajima decides to rescue them himself. He arrives in a tank and destroys the clubhouse, and when confronted by the police, claims that he's making a movie. He beats up the Rakkyo group, earning the respect and admiration of the Otokojuku students. In the final scene he rides off into the sunset on his tank.

Tsubakiyama Kiyomi is having trouble coping with the physical rigor of training at Otokojuku and decides to escape at night with his pet canary. He is intercepted by the Second Year student Oniyokozuna and challenged to a contest. The First Year students are woken by the staff at 4am to witness a Spike Thicket Sumo contest between Tsubakiyama and Oniyokozuna. Tsubakiyama is being beaten badly, but when he realises that Oniyokozuna ate his pet canary, he fights back with a vengeance, and with a little help from Momotaro wins the contest. Later, at the grave of his bird, Tsubakiyama is attacked by other Second Year students. As he is being beaten, Momotaro again intervenes and Tsubakiyama finds his strength and courage. He eventually decides not to leave Otokojuku.

To take revenge for the defeat of Oniyokozuna, some Second Year students start beating up on First Years. Momotaro stops the First Years from taking immediate revenge as it is against school rules to lift a hand against a more senior student. The First Years are then invited to a Meeting Ceremony with the Second Years. The ceremony consists of a series of humiliating and deadly acts to be carried out by the First Years. Momotaro finally acts and challenges the Second Year acting head Edogawa, beating him with one kick, ending the meeting. When the instructors prepare to expel him, Principal Edajima reminds them that Momotaro did not raise his hand, thus not breaking the rule and will not be expelled.

Second Year leader Edogawa invites the First Year students to an outing at the Orient Safari Park. The rules are that the First Years must split into groups of three and spend the night in the park with the wild animals. Edogawa dons a gorilla suit to take his revenge on Momotaro, but fails when a lion befriended by Momotaro attacks him. When Edogawa cries for help Momotaro beats him savagely, accusing the gorilla of impersonating Edogawa. The First Years return to Otokojuku unscathed.

Following the loss of his last hair, Principal Edajima decrees that all First Years must shave their heads, unless one student can perform the Head Seal. This involves writing the word "man" (男) on the Principal's head. All the attempts by the students fail until Momotaro tricks the principal into putting on a helmet with a stamp on the inside performing the Head Seal . Instructor Oni-Hige then has his own head shaved as the result of losing a bet with Momotaro.

Tsubakiyama chases his pet squirrel onto the Second Years' lawn but balk at punishing him when Momotaro appears. The instructors are concerned at the Second Year's cowardice. Principal Edajima calls back the former head Second Year student, Akashi Gouji to take on Momotaro. On his return he invites the First Year students to a 2nd-Year head's Reinstatement Ceremony. After humiliating the former acting head Edogawa and some First Year students, he engages in a sword fight to the death with Momotaro. The Principal decides to use the fight as an opportunity to stage a public contest on Ganryu Island. The school then sells tickets to raise the necessary funds to pay the school's bills.

On the day of the planned sword contest on Ganryu Island, Momotaro decides that he doesn't want to fight and be part of a tawdry money-raising spectacle. Togashi volunteers to take Momotaro's place, but is outclassed and wounded. When Akashi is about to deliver the killing stroke, Momotaro arrives to represent the First Year students. The battle between Momotaro and Akashi is fierce, but Momotaro uses his own spirit to counteract the Rock-Slicing Sword technique of Akashi and defeats him. Unfortunately the instructors bet all of the ticket money on Akashi and lost the lot, so the school no longer has the money to pay its debts.
