(The Reporter is seen looking at the news of the explosion which happened in the end of the King of Iron Fist Tournament 4.)

Reporter: It all started with an explosion in the heart of Mishima Estate... At the time, the media reported it as an unfortunate accident. But when strange truths began to come to the light, things didn't appear quite so clear cut... After the explosions, came the death of a number of G Corporation executives. Newspapers put it down to a coincidence- a series of tragic occurrences. But the truth was far more sinister... In reality, an attempt by G Corporation to take out one of their own had failed, and the man they targeted came baying for revenge. The missed target's name was Kazuya Mishima. After disposing of the guilty parties without so much as dirtying his hands, Mishima began to manipulate the G Corporation from the shadows.

(Cut to the skies, a plane is seen heading to Italy. Inside of it are Heihachi, Nina, Chifuyu, Ace Ops, Sai, Sirzechs, Rias and her Peerage (minus Rossweisse and Xenovia), Ozpin and Michael.)

Chifuyu: The Sirius Marksmen... Says here they're based in Italy. A society of exorcists who've historically held influence throughout Europe...

Issei: I heard Irina and Xenovia are with them. (turns to Rias) What does Heihachi want with them, buchou?

Rias: I should be asking the same thing...

(Heihachi overheard the conversation.)

Heihachi: Jin used the Zaibatsu to cause this chaos. If it's world domination he seeks, defeating Kazuya would mean nothing. More than that, he needs public opinion on his side.

Nina: Surely you can't be... planning on using the society's underground network?

Sirzechs: She has a point, Heihachi. I mean, my sister and I came from a family of pure-blooded devils, and the members have been reincarnated as such.

Heihachi: When people discover that G Corporation is ruled by a flesh-and-blood devil, I shall come to be seen as humane, the bearer of truth. The tournament will be the perfect stage on which to inform the world of this.

Ozpin: Hmm... so this is your plan.

(The plane goes close to Italy.)

Heihachi: Our destination is at sight.

(Timeskip)

(Heihachi and his group are seen at Sirius Sanctuary.)

Sai: Raiding their HQ for not returning your calls... You're quite the negotiator.

Heihachi: If at first you don't get the answer you want, naturally you must force it out.

Nina: If you say so...

Clover: (looks up) Watch out!

(The Marksmen Army shows up as Marrow and Vine kick two of them. Xenovia and Irina come in as well.)

Xenovia/Irina: Infidels have invaded our sanctuary. (point their weapons) Slay them!

(The Marksmen start shooting, but Harriet defeats two of them while Issei and Kiba charge at Xenovia and Irina, who block their attacks.)

Irina: Issei? Is that you?

Issei: Good to see you again.

(Heihachi is seen holding a Sirius Marksman in the neck.)

Heihachi: Your playthings are no match for me!

(That's when Claudio shows up.)

Claudio: So the man in the flesh- The rumors about you weren't wrong, Heihachi. I'm just impressed you could play smart and bring out a bigger army this time.

Heihachi: Claudio, I presume? The world's most powerful exorcist...

Claudio: I believe I declined your offers. Not that you would take a "no" as an answer. (smirks at Ozpin) Right, Ozma?

(Ozpin's eyes widen by having his real name revealed.)

Michael: Looks like you're not the leader of the Sirius Marksmen for nothing.

Claudio: The Sirius Marksmen are unique, our history one of proud independence.

(He then jumps to face Heihachi himself.)

Claudio: We have no intentions of subordinating ourselves to a corporation's whims.

(Heihachi steps up to face Claudio.)

Heihachi: That's your concern, not mine.

Claudio: I have no time for meaningless negotiations.

Heihachi: You know of the purpose of my visit, it would seem.

Claudio: In that case, I shall devise another way to make you listen to reason.

(They fight, and Claudio shows why he is the leader of the Sirius Marksmen. As the fight goes on, Claudio gets more serious, but Heihachi eventually defeats him.)

(Meanwhile, Rias and her peerage are seen fighting Xenovia and Irina. Rias then prepares her Rage Arts.)

Rias: Feel the power of my peerage!

(Rias launches a spell of Destruction at Xenovia and Irina, and then Akeno stands in the middle of them.)

Akeno: Scream for me!

(Akeno unleashes several thunderbolts at them while Kiba and Koneko rush at them and attacks them rapidly. Issei then activates his balance breaker.)

Issei: It's over. DRAGON SHOT!

(They defeat Xenovia and Irina. Issei approaches them and helps them up.)

Issei: Asia, come here and heal them, please.

Asia: Hai.

(Asia approaches the duo and heals them with her Twilight Healing.)

(Back to Claudio, he glares at Heihachi.)

Claudio: You... you are a human with the strength of a devil...

Heihachi: (crosses arms) That is correct! I am indeed human. And yet... the same cannot be said of my son Kazuya.

(Nina comes in and shows the picture of Kazuya's real form.)

Claudio: This... this devil... You truly mean to subdue such an abomination?

Heihachi: You see now the sincerity of my intentions. We all seek the same thing... to bring down the devil himself. My fists have settled it. You will see the public is ingratiated to our cause.

(As they walk away, Xenovia and Irina approach Claudio.)

Xenovia: My apologies, sir. But I'm with them.

Irina: Me too.

(They then walk away, leaving Claudio to take reflections as the chapter ends.)
