She is Guest's junior from high school. Though small in stature, she is serious and reliable. Her beloved guitar is a Mustang named Muttan. She has been a member of the light music band "Houkago Tea Time" (HTT) since high school. Being a year younger than the other members, she was doted on constantly. She is kind once she opens up, but she often maintains a cool and composed attitude. She earned the nickname "Azu-nyan" because cat-ear headbands suit her so well; though she was initially displeased, she has completely grown used to it by now.
