One day, while returning home, one of the neighbors tells him that his father has hung himself after finding out he was arrested. His father left a letter, writing that his father does not want to have medicine if it’s from the wrong activities.
Then, having no place to go, he starts beating people, and one day he kills seven people in a village. In the village, he meets Keizo and offers him the battle, but Hajuki loses the fight. Also, Keizo took Hajuki and started to teach him martial arts.
