A scarlet-haired male was ordering others around, but not necessarily in a rude fashion. You could tell he was blunt, mainly by the lack of facial expressions and the way he spoke. As he noticed you out of the corner of his eye, he gave them final instructions and waved them off, leaving them to do their own thing. 

"Who are you?" He plainly asked, red eyes looking you over as he raised an eyebrow. He was wearing a swim suit, and he had a pair of goggles in his hand. "Looking to join the team? Well, uh, sorry to say that it's full, not taking any more members," he huffed. "I'm Rin Matsuoka, captain of the Samezuka Swim Team," he grinned with pride, and that was when you noticed his very shark-like teeth.

Watching your eyes, he smirked and chuckled. "Yeah, these are my real teeth. Don't think that I'm some freak who sharpens them for fun," he glared a bit at you, then crossed his arms. "They scare my opponents too, call me a shark a lot of the time. Judging how fast I am, I don't blame them." He obviously had a lot of confidence in himself, by the way he acted you could tell. 

"I specialize in two swim styles. Free, and butterfly. Doubt you could beat me in either, you're all twig like," he frowned, turning away. "Anyhow, I need to get back to my team. You just go back to wherever you came from, I have work to do." He slipped his goggles on, and dived into the pool.
