Yori is a student from the Yamanouchi and a highly skilled ninja. She first appeared in “Exchange” when she was sent to receive Ron and guide him to the Yamanouchi School, and served as a support for him during that episode, developing a strong bond with him. She later reappears in some few future episodes. Yori is usually calm, even in dangerous situations, and kind to the point of showing more concern for others than herself.
As a fighter, she is very reliable (given the fact that, in Japanese, her name means 'reliable'), but has demonstrated a preference to act as a subordinate rather than a leader, and has also shown to value teamwork much more than individuality. Yori is actually a better fighter than Kim. In one episode when a villain, Yono the Destroyer, turned Kim to stone he wasn't able to turn Yori into stone. She is also very optimistic and believes a lot in her friends. From her introduction, Yori has appeared as a strong love interest for Ron, winning his interest at first sight and gradually developing feelings for him, which were confirmed as romantics during Yori’s second appearance. However, this relationship was exiled during the series’ fourth season, since Ron had starting dating Kim, and Yori has not expressed any concern about this relationship. Also, Ron was completely oblivious to her feelings towards him, to the point Kim had to point out that she "liked-liked" him. A running gag is that Yori talks very much about honor, to Ron's chagrin, such as, when he faces a long walk and asks for a ride, Yori says that it is "his honor to walk".
