Position: Runner
Riku's the kind of guy who gets along with everyone—he's genuinely upbeat and friendly. He's naturally athletic with solid coordination, though his cardiovascular fitness is just average for a runner. Multiple school clubs have tried recruiting him (basketball, volleyball, table tennis), mostly banking on his speed and quick reflexes rather than any particular skill with a ball.
What makes him stand out is his acceleration—he can explode off the line. But he's got a weird blind spot: his parkour skills are terrible. He can jump and clear hurdles fine, but sticking the landing? Not his thing. It's a recurring problem.
When he's not training, Riku's into Japanese soba and bread, and he'll pretty much try any sport. He enjoys walking too. The one exception is kabaddi, which he can't stand. Interestingly, his older brother loves it—and whatever that means to Riku, it's definitely not appealing to him.
