He realizes that his devil form caused the destruction. He blacks out shortly after fleeing Hon-Maru and wakes up in a destroyed forest. Meanwhile, Jin Kazama's Devil Gene causes him to lose control.
Speaking into an earpiece, he reports, 'Heihachi Mishima is dead.' A mysterious character, Raven, watches the scene from a nearby cliff. While Heihachi is restrained, the robots self-destruct, destroying Hon-Maru. During the battle, Kazuya escapes after betraying Heihachi and throwing him into the path of the robots. Kazuya and Heihachi begin fighting as a team against the robots. Shortly afterwards, just as Heihachi and Kazuya are coming to, numerous Jack-4 robots deployed by G Corporation crash through Hon-Maru's walls and attack. Jin ultimately defeated his grandfather and father and fled the temple in his devil form. The King of Iron Fist Tournament 4 concluded with a face-off between three generations of the Mishima family – Heihachi Mishima, Kazuya Mishima, and Jin Kazama – in Hon-Maru.
