Lili joined The King of Iron Fist Tournament 5 without her father's knowledge and was subsequently crushed by Asuka Kazama. Unfortunately, her father discovered that she had entered the tournament and banned her from leaving her home. As a result, Lili was unable to take revenge on Asuka.
It was then that Lili's father's oil field was taken over by the Mishima Zaibatsu. His company fell into disorder and he collapsed, overworked. Concerned for her father's wellbeing, Lili searched for a way to alleviate her father’s anxiety. She decided to reclaim the oil field that the Mishima Zaibatsu took from her father. While formulating her plans, the Mishima Zaibatsu announced The King of Iron Fist Tournament 6: an excellent opportunity to win back the oil field. So Lili joined the contest to help her father.
