Aoi Kiriya is a sharp-minded student at Starlight School and the lifelong best friend of Ichigo Hoshimiya. Raised in traditional arts such as piano, violin, horseback riding, and calligraphy, she discovered a deeper passion for the creative freedom of idol culture after witnessing Ichigo’s spontaneous dance at a festival. Her encyclopedic knowledge of idols and the entertainment industry earned her the nickname “Idol Professor,” and she achieved a perfect score on Starlight School’s idol theory entrance exam, outshining nearly one thousand applicants. Aoi has cobalt blue hair often styled in a side ponytail secured with a light blue scrunchie, vivid blue eyes, and a pale complexion. She stands 157 centimeters tall, was born on January 31st under Aquarius, and has blood type A. Typically calm, mature, and analytical, she balances a perfectionist streak with quiet anxieties about potential diverging paths in her shared journey with Ichigo. Her catchphrase is “Odayaka janai” (“This isn’t ordinary”), she favors sandwiches and leeks, and she avoids spicy foods due to a sensitive tongue. She never forgets an idol once seen and proudly declares herself Ichigo’s number one fan. Aoi became Mizuki Kanzaki’s temporary manager after winning an audition and later formed the unit Soleil with Ichigo and Ran Shibuki, navigating initial friction with Ran to build a strong partnership through tours, theatrical projects like Naughty Detectives, and collaborative competitions. She ventured into acting, starring in the hit film Naughty Inspector, and during a high-stakes constellation battle representing Starlight School, she selflessly yielded the spotlight to Ichigo for the school’s success. Her preferred brand is Futuring Girl, with blue as her signature stage color, and she sometimes coordinates her hair and eye color with her performances. She placed as runner-up in the Starlight Queen Cup. In the events of Aikatsu! 10th Story ~Mirai e no Starway~, at age twenty-two, she pursues a career as a solo actress and idol.
