Saho Mizuo, a third-year Course 1 student at Third High School, balances a supportive nature with fierce competitive drive as a key participant in the Nine Schools Competition. Recognizable by her short brown hair, bright yellow eyes, and signature headband, she carries herself with the poised demeanor of a seasoned competitor, often seen in her crisp school uniform. During the 2095 competition, Saho clinched victory in the Women’s Official Division Battle Board event after Mari Watanabe’s injury and a rival’s disqualification, demonstrating tactical precision and calm adaptability to steer her team to triumph. Her magical heritage as a Water Elements descendant, reflected in the “水” (water) kanji of her name, hints at a lineage intertwined with elemental affinity, though documented specifics of her abilities remain undisclosed. Beyond competition, Saho prioritizes mentorship. When Shiori Kanou faltered after losing the Rookie Speed Shooting event to Shizuku Kitayama, Saho’s empathetic encouragement helped Shiori rebuild her resolve. Esteemed by peers like Airi Isshiki for her approachability, she serves as a trusted confidante, offering guidance that cements her reputation as a reliable upperclassman. Her collaborative instincts shine in team settings, where she mediates conflicts and uplifts morale. Whether strategizing for competitions or fostering unity, Saho consistently channels her efforts toward shared goals over personal glory, solidifying her role as a stabilizing force within Third High’s delegation. Available records focus solely on her contributions during the Nine Schools Competition, with no elaboration on her broader background or appearances in alternate media formats.
