|Anime Debut||Season 1 Extra Episode: Live House!|
Aya attended Ho-Kago Tea Time's performance at the school festival (she even remembers Yui Hirasawa as "the one who showed up late"), and is one of the first people (or "strangers," as Ritsu Tainaka puts it) outside of the school to compliment the band. Aya is a big fan of Mio Akiyama, as she also plays bass. She and her bandmembery Maki and Shiho invite the band to attend their own show in the future, and Aya gives Yui a Love Crysis CD, which inspires Yui to come up with a band logo.
In the movie, Aya and her band appear in London, giving Ho-Kago Tea Time once again the chance to perform at a live stage.
Aya has shoulder-length brown hair and usually wears her band's trademark, an orange pullover.
