Lili is a Monégasque teenager who is the only child of a pacifistic oil tycoon. At the age of twelve, she had been held for ransom by a group of thugs, but unwittingly took out one of her captors in her attempt to break free. Lili consequently took pleasure in the thrill of defeating her opponents, but her father wants her to grow into a prim and proper lady and not a fighter. She nonetheless steals his private jet to travel abroad and compete in street fighting competitions. This gains the attention of an unknown individual who invites her to compete in the King of Iron Fist tournament, but Lili notices that the tournament organizer, the Mishima Zaibatsu corporation, had caused her father problems in the past. This makes her determined to emerge victorious and put an end to this situation, but she is thwarted by her rival Asuka Kazama, a relative of Mishima Zaibatsu CEO Jin Kazama. Before Lili can attempt to seek revenge, her father learns of her participation and confines her to the family home as punishment. However, the Zaibatsu later annexes her father's oil fields, negatively impacting the business and causing him to suffer anxiety attacks. Lili therefore again defies her father's policy of nonviolence and enters the sixth tournament to take back his property. In "Tekken 6's" "Scenario Campaign" story mode, Lili attempts to infiltrate the Mishima Zaibatsu and hunt down Jin, but she first has to go through Lars Alexandersson and Alisa Bosconovitch in combat, which she fails. Gracious in defeat, she provides the duo with a new sport utility vehicle that she had previously received as a birthday gift, and makes them guarantee in turn that they will defeat Jin. In "Tekken 7", Lili enters the seventh tournament without telling her father for the second time to fight Asuka once again.
