Azusa is a new student who joins the light music club and plays a Fender Mustang electric guitar but she is also in possession of a Gibson Les Paul Custom 50th Anniversary Gold Top (as seen in episode 13). A self-proclaimed novice guitarist who has been playing the guitar since the fourth grade and whose parents are working in a jazz band. She is in the same year and class as Ui and has quite a mysterious demeanor. She often finds herself bewildered by the tea parties and cosplaying aspects of the club, when she would rather just practice and is curious on how the club is able to play so well despite their problems and lack of practice. However, she has a certain weakness for cakes and can be calmed down rather easily, sometimes by just being petted. She could be described in part as a tsundere. She is constantly hugged by Yui and is nicknamed Azu-nyan after trying on a pair of cat ears and meowing. In the band, she looks up to Mio the most due to her maturity and the fact that she is an experienced bassist. Since joining, Yui comes to her for advice on playing guitar, as well as maintenance.
