As a child, Jun Kazama watches as Kazuya Mishima is thrown off a cliff by his cruel father, Heihachi, who considers him weak and good-heated. She tries to locate him, but fails and Kazuya is considered dead. Kazuya, however, only survives and vows revenge, selling his soul to the Devil in exchange for his own survival. Sixteen years later, Jun works as an Interpol agent and is assigned with a partner, Lei Wulong, to investigate Mishima Zaibatsu for allegedly inhumane animal experiments, infiltrating the next King of Iron Fist tournament. Kazuya also plans to enter, hoping for a chance for revenge. Heihachi's adopted son, Lee Chaolan, tries numerous times to kill Kazuya in advance for Nina and Anna Williams, as Heihachi plans to leave Mishima Zaibatsu to Kazuya, should Kazuya defeat him in the tournament. Nor are they able to succeed. Jun and Lei board a boat towards Mishima Island, where the tournament will be held, and Jun recognizes Kazuya when he gets on board. She confronts him at the gym about his past and tries to convince him to walk away, but Kazuya refuses, especially after Nina and Anna attack again and barely manage to kill Kazuya.
