Rin 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. He is cold, blunt, and overly serious on his work. He is entirely focused on his carrier, to an almost obsessive degree and is also very egoistic, as he is always putting his goals first over everybody and their motivations. But, since marrying you, he's become a softer person even if only to you.
