—Rin Itoshi

Rin is a tall, lean yet muscular teenager. Although he appears slender, his muscles aren't overly defined, simply showing a good physique. He is noticeably taller than Yoichi Isagi, who is five months older. He has dark turquoise-green hair with bangs that lightly cover his face, especially his right eye, which is slightly to the side. He has calm, almond-shaped turquoise eyes with distinctive eyelashes, similar to his brother Sae Itoshi's; his lower eyelashes are beautiful and well-defined. As a child, Rin has a practically identical appearance; his facial features only become more defined as he grows, but his eyes were more lively and open.

to perish. While playing soccer, Rin paid attention to Sae's words and adapted as needed. When Sae left for Spain, Rin realized that playing soccer was more difficult without his brother, but even so, he longed to imitate him and take his place. It was at this point that Rin's fundamental approach to the game began to transition from an intuitive style to a more analytical one.

Initially, he was an excellent team player and leader on his elementary school team, seemingly having a friendly relationship with many of his teammates. However, due to conflict with his brother, he became distant, cold, and overly serious. He is completely absorbed by soccer, to an almost obsessive point, and is quite egocentric, constantly prioritizing his ambitions over the aspirations of others. Rin takes great pride in being a striker, bordering on arrogance, as he frequently labels the soccer skills and mentalities of others as "mediocre" or "lukewarm." These mannerisms and actions originate from his brother; in trying to imitate him, Rin mirrors his speech and adopts his mentality.
