Ai Miyashita is a second-year student at Nijigasaki High School and a member of the school’s idol club, where she performs in the subunit DiverDiva. Her image color is ultra orange. Raised primarily by her grandmother while her parents worked long hours at the family restaurant, she formed a close childhood bond with her neighbor Misato Kawamoto, whom she considers an older sister. To cheer up Misato during illnesses, Ai developed a habit of using puns and jokes, which became a core part of her personality. She carries this familial warmth into school, often affectionately referring to people in her neighborhood as siblings. Highly sociable, energetic, and caring, Ai makes friends easily across different groups. Despite her gyaru fashion sometimes leading to misconceptions about her attitude, she excels in both studies and sports, maintaining high grades while participating in multiple club activities. She speaks casually with slang and frequent puns, though others often find them unfunny. Ai remains down-to-earth and unaware of her reputation, always genuine. She is supportive, especially toward Rina Tennoji and Misato. Physically, she has an athletic build, stands 163 cm tall, and has light blonde hair usually tied in a ponytail with orange eyes. Her hobbies include mobile apps, gaming, fashion, candy, and especially her grandmother’s fermented pickles. She often helps various school clubs as a substitute member, building friendships, and works on the Famitsu App alongside Ayumu Uehara and Rina Tennoji, learning about media production perspectives to apply to her idol activities. Ai joined the idol club after a friend challenged her to explore its “unseen world,” sparking her curiosity and competitive spirit. She aims to become a top school idol to share new experiences and make her grandmother proud, emphasizing enjoyment and high spirits in her performances.
