Yori is a student of the Yamanouchi Kinja school in Japan whom Ron Stoppable has a crush on. After Kim, she appears to be the most popular of Ron's crushes. In the episode "Exchange", Ron shows repeated interest in Yori, both at their meeting, where he is stunned by her appearance, and again later, when Fukushima is informed that he was right to save a pretty girl. At this time, Ron is not aware that Yori herself has feelings for him. On their second meeting, Ron tells her of his relationship with Kim, which she accepts. Kim shows clear jealousy of Yori, possibly due to Kim believing her to be her greatest competition for Ron's affections.
