Tetsuo Minamino

Tetsuo Minamino is a 17-year-old gymnastics prodigy who earned the nickname 'Headband Prince' from the media due to his unwavering habit of wearing a headband during every performance. He once looked up to protagonist Jotaro Arakaki as a personal idol, but growing disillusionment over Jotaro's declining form turned that admiration into open rivalry — even prompting Tetsuo to confront him directly and demand his retirement. Sharp-tongued and intensely driven, Tetsuo holds himself and those around him to an uncompromising standard, with his sights set firmly on becoming the world's number one gymnast. He stands as both the most formidable obstacle and a crucial catalyst in Jotaro's journey to reclaim his former self.
