Tekken 6 marches you through the narratives behind the previous five games in its opening moments. It's all self-important hoo-hah. Somebody is mad at somebody else, so they got into a fight; somebody betrayed somebody, so they got into a fight; and blah blah blah. Coming up with these things must be like those old Mad Libs books. The dev team probably has a sheet of paper with sentences on it that go like this: BLANK was BLANK at BLANK, so they got into a fight.
