Appearance
Haryu is a tall, athletic third-year with the build and bearing of Eimei badminton's top standard. His expression in training is severe, the look of a player who counts a partner's wasted effort as a personal insult, which makes his off-court steadiness, when it appears, all the more noticeable.
