Ryuhei Aoi works as a coach at Southern Tennis Club, where he's best known for mentoring Eiichirou Maruo as he works toward going pro. He's a former professional player himself—an injury forced him to step away from competitive tennis, but that experience clearly shapes how he approaches coaching.
What stands out about Ryuhei is how he balances toughness with a laid-back approach. He wants his players pushing hard, sure, but without burning themselves out or losing sight of the fundamentals. He's told Eiichirou that instinct and technique have to work together, or you'll end up losing everything that made you good in the first place. It's the kind of advice that comes from someone who's been through it.
He genuinely cares about his students' wellbeing too—fans often note how he'll step in and pump the brakes when necessary. When Eiichirou got ahead of himself trying a fast serve without proper training, Ryuhei stopped him cold. That protective instinct is just part of who he is as a coach.
