Kaoruko Serigaya

Kaoruko Serigaya stands as one of Kounan High School's most formidable badminton players, driven by an obsessive rivalry with Ayano Hanesaki. Her fixation traces back to a middle school victory over Ayano during an off day—a win that left her both proud and unsatisfied. On the court, she projects an air of superiority and delights in psychological provocation, yet behind closed doors she is a relentlessly hardworking athlete who dissects opponents through meticulous data analysis. Her ability to exploit weaknesses with calculated precision makes her a genuinely dangerous competitor.
