Rin is a surprisingly tall teenager with a slim but powerful build. He is noticeably taller than Yoichi Isagi who is 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,Rin is cold, blunt, and overly serious. He is entirely focused on his job of shinigami, to an almost obsessive degree and is also very egoistic. Rin seems to respect almost nobody.
