"The happiest kid in the world" is the title of this chapter's opening soliloquy. It's the first day of school, and Tachibana is so happy to see him that he coughs a lot. He asks Tsuku-chan what's wrong with him, and he tells him to take care of his lungs. Tsukuchi-chan says he's just buying a pair of new lungs, and that he'll have 630 yen by the end of the school year. Tchibana-chan tells him he can't give it back, because he just picked up some nunchaku techniques from a guy named Bruce Lee, who's been teaching him how to do the same thing. He's not sure what to do with the phone, so he gives it to Tsuka-chan and asks her to come with him to a game of futsal that Tsuko-chan is playing with some friends. The two of them are friends, and they've been hanging out together for a while, so Tsaku-chan invites them to come and play with him. He tells them that he doesn't want to risk his life to play with them, but he promises to make it happen.
