In this chapter, we learn that Hiroshi's band is planning to perform a song called "Climber's High," written by Hiroshi himself. The song is a ballad, and Hiroshi wants to sing it with his friend, Niko, who plays the bass. He wants to play the song "da-da-do-do," which means "do two strings in-do" and "do land time with-do." The song, he says, is so thin that it's hard to play. He's going to play it with Niko on drums, and he's not going to let her go along with it.
