Aira is the main protagonist of this TV anime. She is a junior high school girl who one day was accidentally scouted by a man named Jun to be a Prism Star. She was born on September 3, 1997. 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. She was the first of our two heroines to perform a prism jump. She also really likes clothes and especially Shou's store called Prism Stone. Her father is very protective of her. She claims that she loves Shou's designs, not him. She had gone on a date with Shou to the fireworks festival. It is clear to Rizumu and Mion that she likes Shou, which isn't good from her father's point of view. She is excited when she travels to a new place and isn't afraid of dark places.
