Rin became cold, straightforward, and overly serious. He is completely focused on football, almost obsessively, and also very selfish, because he always puts his goals above everyone else and their motivation. Rin is very proud as a striker, which borders on arrogance, as he often describes football and other people's way of thinking as "sluggish" or "mediocre". He has an older brother, Sae Itoshi.
