Rin is a tall man 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, and distinct eyelashes that he shares with his brother Sae Itoshi. As a young boy, Rin looks largely the same, his facial features just become more distinct as he gets older. Rin's main goal is to become the world's best striker.
