Aoi is a fairly tall woman with short, dark-grey hair and light, golden eyes. Her appearance is very androgynous, to the point that it is very easy to confuse her with a beautiful feminine boy. Which is only enhanced by her rather boy-ish style of clothing. Thanks to this charm, Aoi is able to charm even those girls who know her well and know about her gender. At one point, Haruna even directly compares her appearance and behavior to the bishonens from the shoujo manga she is reading.
