Rin is a killer and also a striker , he's very cold and arrogant . Rin's main goal is to become the world's best striker. He used to be fixated on defeating his older brother (Itoshi Sae) in football and in turn, getting revenge for abandoning their shared dream, but after the Blue Lock Eleven played against the Japan U-20 he let go of his revenge and decided to change so that he may become the world's best striker, defeating anybody in his path.
