Aira is a junior high school girl who one day was accidentally 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. She was the first of our two heroines to perform a prism jump. She also really likes clothes and especially Shō's store called Prism Stone. Her father is very protective of her. She claims that she loves Shō's designs not him which may actually be a lie. She had gone on a date with Shō to the fireworks festival. He did unintentionally make her blush a few times through the episode by holding her hand or hugging her for example. It is clear to Rizumu and Mion that she likes Shō the most which isn't good from her father's point of view. She and Rizumu had a girls talk about how girls sometime look at boy's lips and touch their own lips when talking to them. She asked Rizumu if she has tried it on Hibiki only to make her blush and talk about Aira and Shō. Aira says that they aren't like that but she seems to be blushing and imagining the scene. She finally reveals to Rizumu and Mion that Shō kissed her on the forehead in the first episode. She is excited when she travels to a new place and isn't afraid of dark places. She continues to believe that she admires Shō and likes him because he is an amazing person.
