As the daughter of a renowned Prosecutor, Juri took on learning Tae Kwon Do in her teens. Her father began looking into Shadaloo operations. Thus, along with her mother, Juri was kidnapped and was even wounded in her left eye.
She later participates in a S.I.N experiment, replacing her left eye with the Feng Shui Engine and performing various missions for them. In her first assignment, she was sent to assassinate someone, but the operation goes wrong, and Chun-Li is alerted to the situation, eventually coming to blows with Juri. If not for a malfunction on her Feng Shui Engine, Juri would have killed Chun-Li.
Juri was then sent to capture M. Bison’s elite team of assassins, the “Dolls.” While on that mission, Cammy and Guile intercept her and attempt to stop her, but Juri eventually beats them and escapes back to S.I.N.
Later, while participating in a tournament hosted by Seth, Juri takes advantage of a tiered Seth after his fight with Bison, which Juri had partially orchestrated. She uses the opportunity to destroy his Tanden Engine, effectively killing him.
