Of the Dairangers, she has the most powerful psychic senses. She has mastered deadly wind power. It's not known if Master Kaku was her blood relative or if 'uncle' was just a title. At the heart a gentle, kind soul, Rin is also terribly shy. Rin's heart was fierce and strong. She was very intelligent and difficult to con because one would have to be very sneaky to get past her. She loved her teammates, her Uncle Kaku, her family, with the warmth and strength most people do not have to spare.

A Japanese schoolgirl ignored Rin's shyness to welcome her to Japan. Rin's Japanese was nearly perfect and though she had left China, she was the person on her team who seemed to have the most attachments back home. For example there was her little brother, Roudoshi Guhon. At first he embarrassed the heck out of her, however she loved him very much, but he was the one who had designed the Dairangers' battle equipment and their suits which they summoned with the ki-spark of their will. Rin went into considerable shock when she found out her great uncle was engaged to be to a twenty-year-old woman, but was ultimately happy for him.
