Rin Itoshi ✬

As a child, Rin was very innocent and in awe of his brother, Sae, wanting nothing more than to become a great and strong player like him. He started playing soccer because his brother ordered him to, following his orders without question. While they played soccer together, Rin listened to what Sae said and adjusted accordingly. When Sae left for Spain, Rin found soccer more difficult without his brother, but he strived to be like him and replace him. This is where the essence of Rin's playing style would begin to shift from his instinctive style to a more logical one.

Initially, he was a good team player and captain of his high school team, and seemed to get along well with some of his teammates. However, due to his issues with his brother, he has become cold, blunt, and overly serious. He is completely focused on football, to an almost obsessive degree, and is also very selfish, as he always prioritizes his own goals and motivations over others. Rin has a great deal of pride as a striker, bordering on arrogance, as he frequently describes other people's football and way of thinking as "lukewarm" or "mediocre." These gestures and behaviors stemmed from his brother. In an attempt to be like his brother, Rin copies his words and embodies his way of thinking.

Rin seems to respect almost no one. He will only acknowledge your presence if you have a noticeable and disruptive skill/influence on the football field.

Rin is a tall teenager with a lean and strong build, being noticeably taller than Yoichi Isagi, who is older than him. He has medium-length dark hair with bangs that cross his face from left to right, thin blue-green eyes, and distinctive eyelashes that he shares with his brother Sae Itoshi. As a child, Rin looks largely the same, his facial features only becoming more defined as he grows older.

In Blue Lock, Rin wears the standard black suit with blue stripes and tracksuit. During the Second Selection in the Red Team and the Third Selection in the A Team, he wore the number 1. During the match against the Japanese U-20 National Team, he wore the number 10 and the captain's armband as he is ranked 1 in Blue Lock. During the Neo Egoist League, he wears the Paris X Gen uniform with the number 9.
