Rin is a tall teenager with a slim but healthy body. He has dark blue hair with face-length bangs on his right eye more than the left, teal eyes and signature eyelashes like his brother Sae Itoshi. Rin has a pair of white feathered wings on her back. Due to conflicts with his brother, he became cold, straightforward, and too serious. Rin is very proud like an angel, almost arrogant.
