Set moments after "Tekken 4"s ending, Jin Kazama's departure from the Hon-Maru dojo, G Corporation helicopters approach and begin deploying Jack-4 pods into the building. Heihachi Mishima and his son, Kazuya, are awoken to a squadron bursting through the walls. At first, the two battle the Jacks together until Kazuya leaves Heihachi for dead while escaping. The Jacks hold down Heihachi while one activates its detonator, creating a huge explosion that seemingly kills Heihachi. The only witness to the event is Raven, a mysterious ninja clad in black, who relays Heihachi's death to his superiors. Heihachi's death is declared all over the world with everyone foreseeing the end of the Mishima Zaibatsu. However, somebody else takes over the company from the shadows and business continues as usual.
