Aoi is a female in her early 20s attending Seiko University. She has an androgynous appearance as others often mistake her for a feminine boy. She has short black hair and dresses boy-ish but still considers herself as a female. She’s in a band called Rondo and is the DJ. She is mature, hardworking, dedicated and of course painfully oblivious. She is calm and is pleasant to have around. She often binds her chest for concerts. She is quite a womanizer among rondos fans but never notices.
