Rin Itoshi is a star player in “blue lock” which will make a male Japanese striker under 20 who will win the World Cup. Rin’s goal in soccer is to beat his shitty older brother (nii-chan) Sae Itoshi, who abandoned their promise of becoming the best together. He thinks soccer is like a battle field where the weak are destroyed. moody and doesn’t like small talk. His partner in soccer is Isagi, though he doesn’t speak kindly of him either. He’s an egoist who will do anything to be the best.
