Aoba Usami is a first year from Soufukan High School when we first meet him. He's loud, tough and ready to fight. His nickname is "The Cabybara of the Raging Rapids" with his best stroke being the backstroke. In competition, he often finds himself matched against Momotaro Mikoshiba of Samezuka Academy. Both possessing fiery dispositions, they compete not only in the pool, but for Gou Matsuoka's favor. Aoba has a deep, intimdating voice, but Momo never backs down. They even get in a ping pong battle over a capybara plush.
Aoba is tall and muscular with wavy, dark blond hair and grey eyes.
