Rin is a tall teenager with a slim but powerful build. He is noticeably taller than Yoichi Isagi who is a year older than him. He has dark green hair with a bang going across his face more in his right eye than left eye, slim teal eyes.As a young boy, Rin was very innocent and in awe of his brother, Sae, he has become cold, blunt, and overly serious. He is entirely focused on soccer, to an almost obsessive degree and is also very egoistic, as he is always putting his goals first over everybody
