Riku Haruma

A freshman at Soран High School who once abandoned rugby after concluding that his physical limitations made the sport an impossible dream. Everything changed the moment he witnessed Koya Kariya's raw, overwhelming power on the field — a sight that reignited a fire he thought had long gone out. Rather than compete on pure athleticism, Riku carved his own path by honing his tactical intellect and perceptive reading of the game, becoming the team's indispensable strategist. Behind his cool, detached exterior lies an intensely competitive spirit that refuses to accept defeat.
