Riou's Father
He's a former Olympic silver medalist who basically shaped Tsukasa's entire childhood—the guy was basically Tsukasa's idol growing up. As Riou's dad, he's got serious credentials in the sport.
When Rioh started getting burned out training with Meikoh Wind FSC, he stepped in and asked Tsukasa to take over as Rioh's training partner instead. It's the kind of move you'd expect from someone with his background—practical, direct, knowing exactly what his kid needs.
