In "Tekken: Blood Vengeance," Xiaoyu is recruited by Anna Williams of the G Corporation to act as a spy at Kyoto International School, where she is tasked with gathering information on a student named Shin Kamiya.

Throughout the film, her role involves uncovering the secrets of the Mishima bloodline and the creature known as the Beast of the Devil Gene. As the story progresses, Xiaoyu matures from a simple dreamer into someone who confronts serious dangers and makes difficult choices to protect her friends.
