(Back to present, the reporter is still sitting before Heihachi and Ironwood as he found out the truth about Kazumi's death.)

Reporter: So that's how you killed your wife...

Heihachi: She was sent to the Mishima Dojo to murder me. It was meant to be...

Reporter: But why did you drop Kazuya off a cliff? He was just an innocent boy.

Heihachi: I believed that if Kazumi's blood flowed into his veins, he wasn't human. If the fall didn't kill him, I would be proven correct. As expected, he survived. (stern) Looking back, I see now... (clenches his fist) I should have killed him then and there. (stands up) There is only one thing left for me to do, reveal the truth and be judged...

(As the reporter is writing everything in his note, Ironwood had it up to there and decided to speak up.)

Ironwood: (loud tone) You hate us for what happened to your family, do you not?

(These words catch the reporter by surprise as a Tekken Soldier and an Atlas Soldier appear behind him.)

Reporter: How do you know about that...?

Heihachi: (gets up) YOU FOOL. I KNOW ALL ABOUT YOU AND YOUR COLLABORATION WITH LARS AND THE TRAITORS.

(The soldiers restrain the reporter as he struggles to break free.)

Reporter: (stern) Let me GO!

(As both Ironwood and Heihachi walk away, the reporter keeps talking.)

Reporter: (stern) JUST LET ME KNOW ONE THING! WHAT DOES THIS WAR MEAN TO YOU GUYS?!

(The duo remains silent until Heihachi walks away.)

Ironwood: (to the soldiers) Take him away.

Atlas Soldier: (as Ironwood walks away) Yes, my liege.

(He then punches the reporter in the back of his head, knocking him out as everything goes black.)

(The next scene cuts to a wharf, where Lars picks him up.)

Reporter: When I came to, I was on a wharf with Lars. I had no idea on where I was, or what he was doing there. Lars said he'd received a message from both Zaibatsu and Union, telling him to come here. He bundled me into his car, and then took me back to the Violet Systems.

(The reporter is then seen on the back seat of the car as Lars and a fellow rebellion soldier are in the front seat, and they are driving back to the Violet Systems.)

Reporter: As we drove back, Heihachi's words ran through my mind over and over. Why did he let me interview him like that? Why did he leave everything to me? And what was that mournful look in his eyes...? Question upon question whirled through my mind, but not a single answer...

(Cut to Heihachi, he is seen meditating at the ruins of Mishima Estate.)

Heihachi: A fight is about who's left standing. Nothing else. (determined) Let's do this.

(Then the screen goes black, and everything gets quiet until the reporter speaks up.)

Reporter: Everything went down a few hours later.

(The reporter is seen with Lars, Alisa, Lee, Chisato and other rebellion members as they're watching the fight that is about to get started.)

Reporter: I couldn't believe what I was seeing. Lee and Chisato were trying to ascertain Heihachi's whereabouts. Eventually, Lee's spy satellite spotted him and transmitted a picture to us. I stood there in shock.

(The scene of a volcano is seen.)

Reporter: The man I spoke to was somewhere unbeliavable.

(Cut to the volcano, Heihachi is seen standing before Kazuya as Salem, All For One and Belphegor flank the latter.)

Kazuya: Quite the location you've picked to die.

Heihachi: I thought it was apt.

(Heihachi and Kazuya stand before each other with cold glares.)

Heihachi: Let's settle this.

Kazuya: It's time for you to meet your end.

(A dark aura envelopes Kazuya, Salem, All For One and Belphegor while some lightnings and an aura envelopes Heihachi. They charge to attack and both Heihachi and Kazuya's punches collide, creating a small shockwave that pushes both of them back.)

(Salem proceeds to attack Heihachi, but he counters and beats the crap out of the Grimm Queen.)

Heihachi: You deluded fool.

(Salem summons a Grimm, and it hits Heihachi, but then he uppercuts it before striking several blows at Salem until he knocks her out.)

Salem: (grunts) How can I... lose?

(As Salem passes out, Heihachi and Kazuya resume their fight as none of them is at advantage until Kazuya manages to land a punch on Heihachi's face, and smirks as he does so. Heihachi is then sent sprawling as he crashes through a rock. As he gets up, he blocks a flying kick from Kazuya, and tries to attack him, but Kazuya punches him twice. Heihachi then grabs Kazuya's fist, and the latter tries to punch the former, but his fist is grabbed too as Heihachi headbutts Kazuya. As he approaches his stepson, his left eye glows as he roars in anger, and his third eye appears.)

(It shoots a beam that makes a slice out of a battlefield.)

Heihachi: (angry) Damn you... Kazuya!

(As Kazuya's beam hits Heihachi, he then uppercuts him.)

Kazuya: I will destroy everything!

(Heihachi then uppercuts Kazuya and kicks him away.)

Heihachi: I'll snap you like a twig.

(As Heihachi punches Kazuya in the gut, he blocks an attack from All For One, who then kicks him in the gut, but he hits the Number One Villain as he gains incredible advantage, and keeps striking him until the villain gets knocked out.)

All For One: Shigaraki... I failed you...

(Kazuya then charges to strike Heihachi as he sends him sprawling, but the latter is still on his feet.)

Heihachi: Is that it?

(Kazuya responds by kicking his stomach, knocking him down, but he gets back up.)

Heihachi: NOT YET!

Kazuya: (glares) Why don't you just die? That does it...

(Kazuya then transforms into his True Devil Form while Belphegor powers up as well. Heihachi is not fazed at all.)

Heihachi: This is what I was waiting for.

(Heihachi powers up as well, and both he and Kazuya charge at each other, but Heihachi punches Kazuya with his new power.)

Kazuya: I will bury you!

(Kazuya shoots a beam at Heihachi, and kicks him too, but as he is about to shoot another beam, Heihachi dodges and punches him, prompting Belphegor to take action, but gets easily shoved off. Kazuya then gets up.)

Kazuya: Feel the power of the devil himself!

(Kazuya creates a shockwave that blows Heihachi away, but he doesn't give up and attacks Kazuya until he kicks him away. Belphegor tries to use his power to bring him down, but his attempts are in vain due to Heihachi's new power, and he is eventually gets knocked out.)

Belphegor: (weakly) How can... a mere human... ugh...

(As Belphegor passes out, Kazuya had enough of Heihachi, and decides to finish him.)

Kazuya: THIS WILL BE YOUR BURIAL GROUND!

(He punches and then launches Heihachi into the air where he lands an attack, which is followed by a punch which slams them into the ground. Kazuya then charges and fires several laser beams from his chest and wings to finish Heihachi.)

Kazuya: It's over! NOW DIE!

(Everything goes white, shocking everyone around the world. Seconds later, Heihachi is seen laying in the ground, but Kazuya notices something.)

Kazuya: Huh?!

(Heihachi moves his hand, and struggles to get up.)

Kazuya: (stern) You can't be serious.

(Heihachi gets up and roars in anger.)

Heihachi: KAAAAAZUYAAAAA!!!!!

Kazuya: Be quiet, you pathetic fool!

(Heihachi fights Kazuya with his remaining strength as the latter heals twice, but as Kazuya is about to finish him, Heihachi prepares to counter.)

Heihachi: Die, KAZUYA!

(Heihachi strikes Kazuya once and launches him into the air with a Rising Uppercut, then he finishes with his Demon Breath attack.)

Heihachi: Your delusions of grandeur end here!

(Kazuya is launched as he crashes through a rock. Heihachi gets on his knees as he breathes heavily. As the dust settles, Kazuya gets up as he is reverted to his normal state.)

Heihachi: Heh! Still alive?

Kazuya: (stern) Damn you, Heihachi...

(Heihachi and Kazuya approach each other as they punch each other in the face, and they keep striking each other for some time until Kazuya punches his stomach. Heihachi then somehow headbutts Kazuya as he remembers when he tried to avenge his mother, the moment he was thrown into a volcano, and other events that led to the fight he is in.)

Heihachi: You think you're tougher than me? I'll snap you like a twig. Your delusions of grandeur end here!

(Then a quick image of his mother, accompanied by some flashbacks of his past events are shown.)

Kazuya: I'm going to get everything back!

(Kazuya then strikes a final blow at Heihachi, killing him. He then gazes at his teammates.)

Kazuya: I don't need the League of Darkness anymore.

(Kazuya goes to a cliff as he grabs the bodies of Belphegor, Salem, All For One, and Heihachi as he throws each of them into the lava as he gazes at it.)

Kazuya: A fight is about who's left standing. Nothing else.

(The battle is over, but Kazuya has won. What will become of the world now? Will the rebellion be able to stop him? Only time will tell.)
