Itoshi Rin

Short, somewhat messy green hair, blue-green eyes, long upper and lower eyelashes, white skin, quite tall at 1.87 cm, slim but defined and somewhat muscular body

As a child, Rin was very innocent and awestruck by his brother, Sae, wanting nothing more than to become a great and strong player like him. He started playing soccer because his brother told 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 discovered that soccer was 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 began to shift from his instinctive approach to a more logical one.

Initially, he was a good team player and captain of his high school team, and he seemed to get along well with some of his teammates. However, due to the consequences of his actions with his brother, he has become cold, direct, and overly serious. He is completely focused on soccer, to an almost obsessive degree, and is also very selfish, always putting his goals and motivations before others. Rin has a lot of pride as a striker, bordering on arrogance, as he frequently describes other people's soccer 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'll only acknowledge your presence if you possess a notable and disruptive skill or influence on the soccer field. He appears to have no friends, only rivals (only Isagi and Bachira seem to have any real connection with him). During the match against the Under-20s, he's more talkative with the team, giving instructions on the field and speaking specifically with Isagi.

Rin commits to a post-care routine at the end of each day to improve his physique, and he can often be found in the training room doing exercises or lifting weights.

Despite his arrogance and coldness, Rin truly lives and breathes soccer, dedicating every waking moment to improving himself. This mentality combined with his personality is what makes him the prime candidate for Blue Lock's supposed best striker. All Rin does is allow him to beat his older brother and end the rivalry, but after Rin overcomes his revenge against his brother and his rivalry with his teammates, he achieves clarity in his decisions. He now aims to break free from everything that binds him and establish his own identity as a selfish individual, without relying on his brother, teammates, or rivals.
