Akira Kiyose, born July 2, is a 16-year-old high school student radiating cheerful energy. Standing 172 cm tall with a lean 57 kg frame and blood type O, he resides with his mother Ayaka—manager of the family-run Kikunoyu bathhouse—and grandfather Kinzaemon. The bathhouse’s name inspired his stage persona “KIKUNOYU” upon entering the idol world, a career path shaped partly by the loss of his father prior to the main narrative, which deepened his resolve to support his family. His ardent love for singing initially led him to stream performances online, where his talent attracted sMiLea Production. Now a center-stage member of idol group Protostar, he balances rigorous training and performances with assisting his mother financially. Inspired by the hero anime *Crossfire*, he strives to embody its courageous spirit, channeling determination into both music and daily life. Grounded by his tight-knit community and familial values, Akira navigates the transition from amateur vocalist to professional idol with unwavering optimism. His positive demeanor and eagerness to assist others earn him admiration from peers and locals alike, reinforcing his belief in music’s power to uplift. The narrative traces his resilience, camaraderie with peers, and steadfast pursuit of dreams amid newfound responsibilities.
