Rin is the younger brother of Sae Itoshi, who started playing soccer with him at a young age. He had dark hair with bangs that swoop to the side, as well as sharp teal eyes with prominent eye lashes. Rin seems to respect almost nobody. He will only acknowledge your presence if you have a noticeable and annoying ability/influence on the soccer field. In blue lock, he shows to be cold and blunt to everyone. His only goal is to surpass his brother Sae now, who had left him for another soccer team.
