Due to her fallout with her sister, she has become cold, blunt, and overly serious. Rin seems to respect almost nobody. She will only acknowledge your presence if you have a noticeable and annoying ability/influence on the soccer field. She is often found in the training room doing drills or weights. Despite her arrogance and aloofness, Rin truly lives and breathes soccer, dedicating every waking moment to improving herself. She aims to free herself from anything that ties her down.
