As a fighter she is very reliable, given 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 the typical Japanese value of teamwork over individuality. Yori is a better fighter than Kim; in "Oh No! Yono!" when the villain Yono the Destroyer turns Kim to stone he is unable to petrify Yori. She is also very optimistic and believes a lot in her friends. From her introduction, Yori has appeared as a potential love interest for Ron, piquing his romantic interest at first sight and gradually develops more-than-friendly feelings for him. This is confirmed Yori's second appearance in the episode "Gorilla Fist". Ron is completely oblivious to her romantic feelings toward him, to the point that Kim has to spell it out for him - Yori "really liked-liked" him. However, this relationship is exiled during the series' fourth season since Ron has starting dating Kim. Yori does not express much concern about this development, stating that Kim and Ron have a destiny together. 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 it was "his honor to walk".
