Plot
The four Abashiri prepare to rob a large bank as their last work. This bank, however, is in reality a trap by the police, which is ready to expend every necessary resource to end with the Abashiri. Although apparently cornered, the Abashiri overwhelm the police and kill or badly injure several of the policemen. They use so much power that they also destroy a large part of their loot.
After they return to their home, Daemon informs them the reason behind their retirement. Kikunosuke, whom the rest her brothers considered a boy, is actually a girl. For generations the Abashiri believed to have been cursed because no female child had been in the family until the arrival of Kikunosuke. This prompts her mother to request Daemon to stop the criminal activities of the family after Kikunosuke reaches a certain age. Her brothers are surprised by this revelation and the lecherous Goemon takes a special interest in her sister. Daemon intends to send her to a private school where she can become a proper lady. Although Kikunosuke originally refuses, Daemon tricks her into saying that she would try it and forces her to go, under the identity of Shiratori.
The Paradise school, however, turns out to be a criminal school where students have to fight for their survival. Thanks to her strength, she manages to overcome the teachers. At the same time, her brother Goemon is so fixated with seeing her naked that he decides to secretly look for her at her new school. Kikunosuke is able to make a new friend, Yukiko, another girl, who, unlike Kikunosuke, is completely defenseless against the teachers and other students.
For standing up against the teachers, one of them plans to kill Kikunosuke but she easily kills him. He's able however to recognize her true identity and pass the message among the other teachers. As she runs to rescue Yukiko, she realizes that she won't be able to beat all the teachers by herself and ask for help. With the help of the leader of the students, a revolt is formed and the school director orders to kill them all.
Daemon realizes the danger in which Kikunosuke is and with his sons goes to save her. Meanwhile, Goemon manages to arrive to her school only to find Yukiko captive and get himself caught. The students and Kikunosuke (despite being injured) fight all opposition and despite losing several students, are holding on. It's revealed then that the student's leader has been preparing to take the school for himself. The rest of the Abashiri also enter the fight and Daemon recognizes the true identity of the director, Danjuro Namakubi, whom he has fought already two times in the past. The director is able to easily defeat Naojiro. By this point, the students' leader has already betrayed Kikunosuke and uses Goemon and Yukiko as hostages in order to subdue her. Daemon is able to kill the director, but has to surrender to the students leader because he holds Kikunosuke and Goemon while killing Yukiko, who tried to free Kikunosuke.
As the Abashiri are about to be executed, the remaining Abashiri, Kichiza, enters abruptly and with his special explosive costume manages to kill most of the leader's gang and free Kikunosuke, but leaves alive the leader in order to let Kikunosuke deal with him. An enraged Kikunosuke shows no mercy and uses her most powerful technique, the Abashiri 8 God attack, with which she kills the leader in the most painful way. The experience lived makes Kikunosuke cry and Daemon consoles her.
Years later, and old Daemon is shown watching his grandson (named also Kikunosuke) practice the Abashiri 8 God attack while her mother, Kikunosuke arrives, now being a normal woman and thus fulfilling Daemon's wish of her having a peaceful normal life.
