Akira Kiyose is a Tokyo-born high school student who performs under the stage name KIKUNOYU. He stands 172 cm tall, weighs 57 kg, has blood type O, and celebrates his birthday on July 2, making him a Cancer. Driven by a strong passion for singing, he gained attention by publishing performances online, which led to his recruitment by sMiLea Production, the talent agency founded by the retired legendary idol duo Anela. Within sMiLea, he became a member of the idol group Protostar alongside Banri Naoe and Chihiro Isuzugawa, often performing in the center position. His stage name is inspired by his family’s bathhouse, Kikunoyu, where he lives with his mother Ayaka and grandfather Kinzaemon. The loss of his father before the main narrative deepened his resolve to support his family, and he balances his idol training and performances with helping his mother financially. He enjoys watching superhero anime, particularly inspired by the hero series Crossfire. His name carries meanings of brightness, virtue, purity, and swift current. His journey traces a path from anonymous online singer to professional idol, marked by resilience, optimism, and a belief in music’s power to uplift.
