Shuusaku Shida

Shuusaku Shida leads Sōshūkan High's male rhythmic gymnastics club with a signature warm smile, though few realize he was once a formidable ace at Hakumei University. A career-ending injury reshaped him from an arrogant competitor into a well-rounded mentor. Guided by the philosophy of nurturing genuine love for the sport, he leverages sharp intuition to unlock each athlete's potential. Outside the gym, he runs a small diner alongside his wife—a devoted coach by day and a caring husband by evening, admired and slightly mysterious to all who know him.
