**Role:** Bassist
**Instrument:** Bass Guitar
Jun is [Azusa](https://anilist.co/character/21173/Azusa-Nakano)'s and [Ui](https://anilist.co/character/19571/Ui-Hirasawa)'s classmate who often hangs out with the latter. Jun is generally a playful and easygoing girl, but she is sometimes rude without realizing it, compelling [Azusa](https://anilist.co/character/21173/Azusa-Nakano) to reprimand her. [Ui](https://anilist.co/character/19571/Ui-Hirasawa) tries to get her to join the light music club but ultimately fails due to a strange visit to the club room. However, she starts to regret it when she hears about all the activities the club does. She has a pet cat and plays the bass.
Jun has an older brother, Atsushi Suzuki, nicknamed Acchan by her. He plays the bass at a university and helps Jun on "secret training sessions" because she apparently "still sucks at bass".
