(At the outskirts of Kuoh, we see Ryu Black repairing his mecha as he sighs in frustration.)

Ryu: Looks like the Foundation's project was a failure...

(Suddenly he sees three mechas and drones coming close to him.)

(Ryu then realizes something.)

Ryu: Well, I guess it's time for Plan B!

(Unbeknownst to them, Valper and Kokabiel are watching him from afar.)

Kokabiel: Foolish human, neither you nor the so-called Foundation will stop the rise of a new Great War.

Valper: Soon all humans shall perish.

Kokabiel: (smirks) And so will the devils and angels. We Fallen Angels will prevail! HAHAHAHA!!!

(Right now, our heroes are seen at the ORC as Asia heals Issei, Rias, Akeno and Koneko while Chris was being healed/pleasured by his peerage as they were giving him lots of love due to the fact they believed that the power of love would heal their king. Much to the disgust to the others. Sirzechs sighs as he realizes the gravity of the situation.)

Sirzechs: I know Chris and Maya are not in best terms with me and my family, but after The Federation, we seem to have other priorities for the time being.

Y/N: Yes, coupled with the fact they're still at loose, Kokabiel is somehow planning to obtain the four remaining Excalibur pieces.

Claire: And once he does, he will start another Great War.

Sona: (gasps) Did you say... another Great War?

Sirzechs: Not even Azazel would dare to do this as he knows how destructive the previous one was.

Y/N: I have a guess that Kokabiel doesn't care about the consequences as long as he gets what he wants.

Artoria: That explains everything.

Salter: But that's not all. One of those "Fake Successors" is with him and Valper.

(Hearing the name Valper, Kiba gets tense as he remembers the "Holy Sword Project" in which he barely survived.)

Woz: There were six Fake Successors. Three of them were taken care of...

Y/N: While the other three are still roaming around, and one of them must have volunteered to replace Freed.

Sona: Hold on, who was Freed?

Y/N: He was the stray exorcist who allied himself with the Fallen Angels in order to try and steal Asia's Sacred Gear.

(Y/N then turns to Musashi, Roon and Unicorn.)

Y/N: You seem to know those shipgirls, right?

Musashi: (nods) Akagi, Atago, Kaga and Takao are from the Crimson Axis sub-group named "Sakura Empire", where I used to belong.

Roon: Ägir, Friedrich der Grosse, Ulrich Von Hutten and Bismarck are from the other Crimson Axis sub-group named "Ironblood", where I belonged.

Unicorn: I used to be part of "Eagle Union", a sub-group of Azur Lane along with "Royal Navy". Enterprise and Belfast are part of these respective groups.

Atago: And we had fought this "Federation" once. They somehow had more advanced tech, and easily destroyed most of our fleets.

FDG: And as soon as we deal with this Kokabiel and his associates, we'll get our payback at them.

Y/N: Well then, everyone in agreement? Shall we go and face this Kokabiel?

(Issei, Akeno, Rias and Kokeno get healed by Asia.)

Claire: I'm in!

Artoria: So am I!

Enterprise: Let's go!

Belfast: On the way.

(Y/N then turns to his brother and his friends.)

Y/N: Brother, you stay here and take care of Asia. You're not in conditions of fighting after what happened.

(Issei was about to object until Rias patted his shoulder.)

Rias: Your brother is right, Issei. We have barely recovered from The Foundation. Anything we do now will be reckless, and might cost our lives.

(Issei sighs, knowing that Rias is right.)

Y/N: Alright, let's go!

(Suddenly Akagi hugs Y/N from behing.)

Akagi: Ara ara... I must admit you're cute, boy.

(Y/N blushes as Akeno smiles.)

Akeno: I like her.

Enterprise: Great... two of them...

Chris: (gets up) I'll go too. This is my territory!

Eibel: Yes, and you must bow to the greatness of Lord Chris!

Y/N: Tch, make me!

Artoria: Let's just go!

(While OOO is fighting Ex-Aid, the latter decides to change forms.)

Ex-Aid: Dai Henshin!

GACHAN! LEVEL UP! MIGHTY JUMP! MIGHTY KICK! MIGHTY! MIGHTY ACTION X!

(Ex-AId levels up as the screen fades out.)
