Riko Aida stands as the backbone of Seirin High's basketball program, directing the team's tactical development and training regimens as their coach. Inheriting a remarkable gift from her father, a professional sports trainer, she possesses the extraordinary ability to instantly assess an athlete's physical capabilities with a single glance, allowing her to craft highly personalized training plans. Despite still being a high school student, her unyielding determination commands the full respect of every team member, establishing her as a trusted, strategically brilliant leader. Her one glaring weakness, however, is a truly legendary lack of culinary talent.
