Tsuwabuki has still been serving Nanami as if he were her servant. Tsuwabuki's friend, Mari, isn't happy with him for being like that. She says Tsuwabuki is just being taken advantage of because he is just a child. Later, he begins to realize that he is treated as a child by Nanami. He wishes he were Nanami's age. Tsuwabuki asks Utena what he has to do to become a grown-up. Utena says it is probably to experience various things. Tsuwabuki tries to "experience various things" by watching kiss-scenes in films. Mari makes a fun of him, saying it is obvious that one who has experienced a real kiss is more grown up than one who has seen a hundred kiss-scenes. Tsuwabuki tries to do it with Mari and gets slapped. Nanami witnesses. When she asks him about the affair, Tsuwabuki realizes that he is treated as a child after all. At Nemuro Memorial Hall, he confesses that he wishes to grow up right now. Mikage takes advantage of him.
Même s’il ne l’avouera jamais, Tsuwabuki est très amoureux de Nanami. Il fait tout pour passer un maximum de temps auprès d’elle, quitte à devenir son petit esclave. Nanami ne se gêne d’ailleurs pas pour le traiter avec tout son mépris. Peu importe, Tsuwabuki serait prêt à tout accepter par amour, peut-être que l’élue de son cœur se rapproche d’un certain Mikage...
