2 years after the events of the [[Tekken (video game)|King of IronFistprevious Tournamenttournament]], the Mishima Zaibatsu, under the leadership of [[Kazuya Mishima]], has become more corrupt and powerful than ever before and is involved in many illegal operations. While his father [[Heihachi Mishima]] was rather ruthless in his endeavors, Kazuya acts completely without a conscience. He hires assassins to eliminate any of his critics and rivals, attempts to extort money from several businesses and organizations, and smuggles endangered species to conduct genetic experiments on them. The reason for his evil deeds is that he has allowed the Devil within him to consume his soul and mind as a result of his hatred towards Heihachi.
Meanwhile, Kazuya is sentenced to being arrested by animal rights activist and operative [[Jun Kazama]] for his experiments. Heihachi on the other hand, whom Kazuya had defeated and thrown off a cliff two years ago, has climbed back up and is training himself, plotting to overthrow Kazuya and take back the Mishima Zaibatsu. In an attempt to rid himself of Heihachi and his enemies once and for all, Kazuya announces the King of Iron Fist Tournament 2, with a large cash prize of one trillion dollars, knowing that Heihachi will appear in an attempt to get his revenge.
