First-year high school student and contender for the Blue Lock Project. He is the younger brother of Sae Itoshi, a prodigy considered one of the best youth soccer players in the world. Rin once had the aspiration of being the greatest in the world alongside his brother, but after a disagreement, he became obsessed with beating his brother in football to demonstrate he can succeed without him.
Rin is a player who loves to play perfectly efficient football but isn’t hesitant to be daring and take surprising risks to fully embrace the live-or-die attitude he has grown fond of and appreciates. Whether on offense or defense, Rin's play style consists of him grasping the abilities of both his teammates and his opponents and forcing out their best plays and abilities. He either manipulates them in his efforts to score goals for himself or aims to crush them at their strongest.
