Aira is junior high school girl who was scouted by Pretty Top's manager, Takigawa Jun, to debut as a Prism Star and is the main protagonist of the series. She is not very good at sports and is definitely clumsy; but she becomes a different person when it comes to fashion. In the first episode, Aira completed her signature Prism Jump, Fresh Fruit Basket.
Aira is a typical girl, who loves fashion, shopping and cute things. She's also really clumsy and often stumbles. At first she had a bad sense of balance but after the ramen-lesson, in episode 3, it got better. She seems to be more interested in fashion than anything even love. Unlike Rizumu, she seems to be clueless about love. Throughout the anime it seems that Aira possesses the ability to hear the clothes music which probably means she has the talent for the Prism Show. She is probably the only Prism Star that is actually very clumsy in real life like stated by Shou in episode 18. At first Aira wanted to be a charisma model like her idol Takamine Mion but when she started the Prism Show she knew of a different world. Right now she still doesn't know what she wants to do but she seems to want to continue the Prism Show with Rizumu and Mion as her partners. Aira sometimes gets obsessed with clothes. She does seem to panic when Shou does something to her like when he kissed her on the forehead or the hand. Aira is very considerate of her friends and would do anything to help them such as how she gave her Prism Stones to Rizumu in the Tiara Cup finals even though her stones were stolen too or how she helped give Shou a new design despite the fact that Shou yelled at her about her dance skills. She has become more nervous and embarrassed the more Shou is mentioned. She is very nice to everyone even if they make fun of her clumsiness. She is very naïve though. Later in episode 23 she joins Rhythm and Mion and becomes a group called MARs(Mion, Aira, Rizumu) But eventually Aira performs the legendary Aurora Rising Dream in episode 50, which allowed everyone around her float in the air and perform the Aurora Rising. Because of her amazingly naïve and considerate personality she has earned the affection of the boy she seems to have feelings for, Shou.
Aira is an ordinary girl, who lives with her parents and siblings together, her parents own a cake shop and want Aira to take over the shop someday. Before the series started she knew nothing of the prism show. She is shown to always be teased about her clumsiness by her siblings and father. Aira has never actually been very athletic and her father worries about her way too much. Her father has been doting on her ever since she was little to the point where he even buys her clothes which Aira never likes. He calls her clothes indecent for some reason. He won't let her fall in love either which Aira may be in right now.
One day while she was shopping, she discovers the shop "Prism Stone". She sees a dress and imagines to wear it, while she dreams she runs into Amamiya Rizumu. After Rizumu disappears, a man named Jun asked her to come with him and he forces her to participate in the "Prism Show". At the show she also meets Rizumu again.
During the show, Aira was unable to move, so Rizumu did the whole dancing, but the crowd wasn't satisfied because she couldn't show them a prism jump, suddenly Aira's costume started to sing to her and she starts dancing. Surprisingly she manages to make a "Prism Jump", called Fresh Fruits Basket. At the end she fell onto the leader of "Callings", Shou, and he kissed her on the forehead, saying she was amazing. Aira panicked. In the next few episodes, every time she saw Shou, she remembered how he kissed her on the forehead.(she remembered until episode 5)
Later both, Aira and Rizumu get a scholarship for the dance school to learn to perform professionally. There she meets Rabi-Chi her coach. Despite Aira being able to dance well on stage she is still very clumsy and still trips over flat surfaces. Aira thinks that her heart beats for Shou because he is the designer i love it! of her favorite clothes shop but she only thinks. It is unknown if she begins to realize that she may actually have love feelings for him. For example, in episode 18 she is shown to be creating a relationship with Shou. In the latest episode, it is shown and revealed that she and Rizumu have the same birthday. She gets a present from Shou, the person she probably likes the most in Callings which is a dress he made for her. He also kissed her hand just like Hibiki did to Rizumu. She and Rizumu also got to be the first people to listen to Calling's new song. They both seemed to be very happy. It is also stated by Aira's mother Omi Harune, in that episode, that Aira likes their shops cakes, Prism Stone's clothes (designed by Shou) and that she may have interest in Callings. Throughout this ongoing series, Aira is shown to become embarrassed and nervous while blushing whenever Shou is mentioned. It is still unknown if she understands her own feelings. She finally tells Rizumu and Mion that Shou kissed her on the forehead after her first prism show in episode 26. She changed the story the story by saying that he "accidentally" kissed her when she fell on him even though the real story was that he said that she was amazing and then kissed her. She is currently best friends with Rizumu and Mion. She was looking at Shou when Calling's was performing their new song on Halloween night. She finds out that Shou is afraid of dark places but still likes him because she says that he is an amazing person. Shou was going to say something to her but was cut off by Mion's scream and Rizumu's mischievousness. She is shown to always be caught in the middle of Rizumu and Mion's fights with Serena and Kanon. She also didn't seem to mind when Shou called her father Dad in episode 30.

After meeting with her animal coach, Rabi-chi, she was given training methods that helped her master dance. In order to replace Mion who disappeared after her debut, Aira along with Rizumu enters many tournaments in hopes of one day performing in the Prism Queen Cup.
After Aira had mastered dancing, and Rizumu mastered fashion, they were entered into the Tiara Cup tournament where Mion overshadows Aira's win. After they meet Mion, Aira realizes she isn't the personality she had admired. They are given training from Mion and learn to sing and use the batapon which is required in the Summer Queen Cup tournament. Mion at the last minute agrees to let Aira and Rizumu perform because their friendship is the best choice.

Serena and Kanon tie for first place but are dropped to second place by Kaname who performs Aurora Rising. Serena and Kanon are soon dropped to third place by Aira who performs with a blue dress. Rizumu learns Aira wore a blue dress, a symbol of fortune to brides, in order to hope for Rizumu's win so she, Rizumu and Mion can qualify for the Prism Queen Cup. When Rizumu wins second place, Aira, Rizumu and Kaname have found themselves a place in the Prism Queen Cup leaving Serena and Kanon out of the finals.
During the Prism Queen Cup, everyone hopes to see the Aurora Rising, but they are also looking forward to see Mion's new jump that will surpass the Aurora. Kaname fails as she did not manage to throw away her heart and Rizumu performs Aurora Rising Final, but is disqualified when she leaves in the middle of the tournament to reunite with her mother. Mion manages to perform a new jump which surpassed Aurora Rising giving herself a perfect score. However when Aira performs, she manages to complete Aurora Rising, calling it Aurora Rising Dream resulting in her win. From that, Aira becomes the new Prism Queen and decides to restart MARs.
