In this chapter, the protagonist explains that he has a trump card that he can use to defeat the opponent. He explains that the opponent has told him something about him that he doesn't know, and that he's not able to switch genders. He also says that if he fails to persuade the opponent, he'll have to sacrifice everything for "righteousness" . But if he succeeds, he can still use the trump card to subdue the opponent in front of him. The protagonist also explains that if the opponent is able to hit the body of the protagonist, he will be able to tell that the protagonist is his father. He says that this is impossible, because the opponent's soul is now in his body form. This is the first time the protagonist has ever seen the protagonist's body, and he is horrified. He wants to find a white-haired boy who should have been his friend before, but he can't find him. Instead, he wants to give the boy a punch, so that he won't be killed by the protagonist. He tells the protagonist that he and the protagonist are sworn brothers, so they can be considered brothers as well.
