Rin has a lot of pride as a striker, which borders on arrogance, since he frequently describes other people's soccer and way of thinking as "lukewarm" or "mediocre". These mannerisms and behaviors came from his brother; in an attempt to be like his brother, Rin copies his words and embodies his mindset. Rin seems to respect almost nobody. He will only acknowledge your presence if you have a noticeable and annoying ability/influence on the soccer field. He seems to have no friends, only rivals
