Michiru Mayumura

As a talented left-handed pitcher and first baseman for the Oubi Middle Baseball Club, this formidable athlete serves as a primary rival to protagonist Daigo Shigeno. Although she is the daughter of professional pitcher Ken Mayumura, her true inspiration is Goro Shigeno. This deep admiration for Goro has heavily influenced her development, resulting in a unique pitching style that closely mirrors his iconic form as she strives to reach her athletic potential.
