A prominent third-year student and member of the Miyagi Spirits, this competitive athlete serves as a primary rival to the Mizuki Diving Club. Known affectionately by the nickname ‘Pinky’ due to his unmistakable, vibrant pink trousers, he brings an intense energy to every competition. His long-standing, heated rivalry with Youichi remains a central part of his journey, defining much of his character throughout his high school years.
