Aira is a junior high school girl who was scouted by a man named Jun to be a Prism Star.

She is very clumsy and not very good at sports. Aira always tries to look at the bright side and is a huge fan of Mion. She is very naive but is so considerate of everyone. She has a younger brother who teases her and two little twin sisters who cheer her on. She may be absurdly clumsy but she is very good at coordinating clothes which she may have gotten from her former prism show stylist mother, Omi Harune.
