In this chapter, the girls discuss their friendship with sumino, who has become their constant companion. The girls are amazed at how well he is able to maintain his self-assurance despite the fact that he has no boobs. They are also amazed at his ability to be so kind to akkun, who is not a friend of theirs. They feel that he is too perfect a person to be a friend to a person like yoshiko, who does not have a self-preservation system. They also feel that his friendship with chan is even more remarkable than that of sumino because he is not afraid to stand up for himself.
