Yori

Yori's History

Master Sensei of the Yamanouchi Ninja School arranged for Ron Stoppable to come to Japan through a student exchange program, and Yori was the student chosen to be Ron's guide. Yori and Ron became fast friends, and though he was discouraged by his repeated failures at ninja training, she believed in him. With the help of rogue student Fukushima, Monkey Fist stole the magical Lotus Blade from the school. Yori went alone to retrieve it and was captured. Ron rescued her and returned the Lotus Blade to the school, but was sworn to secrecy about all that had happened in Japan.

Yori later asked Ron for help in finding Master Sensei when he was kidnapped. They tracked down Monkey Fist, believing he was responsible, unaware that Kim and Wade were tracking them because of Kim's suspicions about Yori, who was an unknown to her. Yori gave Ron permission to tell Kim the truth about his time in Japan, and Kim joined forces with them. Their search turned out to be a trap: DNAmy had framed Monkey Fist, knowing that Team Possible would lead her to him. As Yori prepared to return to Japan, she kissed Ron on the cheek and said that she had liked him as more than a friend.

Yori once again called on Team Possible when Monkey Fist broke into the school and stole a scroll, which contained a prophecy of a powerful mystic weapon. Their alliance was made somewhat awkward by the fact that Ron and Kim were then dating, and they expected Yori to be bothered by this, though she was not. Together they pursued Monkey Fist as he visited a series of temples to gradually unlock more details about the weapon. Once Monkey Fist was defeated, Yori returned the scroll to Yamanouchi, and entrusted the temple keys to Ron.

Team Possible returned to Yamanouchi after they learned that Master Sensei had secretly arranged the adoption of Hana Stoppable, Ron's young and curiously skilled sister. However, the school had been evacuated, save for Master Sensei himself and Yori, due to an imminent an attack from Monkey Fist and Yono. In the battle that followed, the school was destroyed, but Monkey Fist was eventually defeated and imprisoned in stone.
