kawakubo

A third-year student at Fujigaya is introduced without a specific timeline. She is nearing graduation but spends all her time following Yamashina-sensei around campus. She boldly declares her love for Hinako and persistently pursues her romantically, even in the face of Hinako's rejections. Kawakubo seems satisfied that Yamashina-sensei rejects her due to their teacher-student relationship rather than because they are two women. She frequently stays in the science lab with Yamashina, where she opens up to her teacher. Kawakubo confides in Yamashina-sensei about coming out to her parents, who reacted poorly, calling her "sick." She is also very interested in Hinako's personal life and only later discovers that her teacher had once dated a woman, though Yamashina never provides more details on this. Kawakubo eventually graduates, but it is a bittersweet moment for her as she leaves school without ever having her feelings for Hinako reciprocated.
