The scene opens up with a JTF soldier opening fire at the Black Tusk with an M16A2, and then James' uncle, Jack covers the JTF soldier with his P416.

Jack: COVER ME!

Jack drags a civilian Militiaman to cover as it later shows James shooting at the Black Tusk with his M4A1.

James: COVER ME! RELOADING!

JTF Soldier: I got you, Agent!

The JTF Soldier fired his M1911 at two BT soldiers, and the door of the warehouse opened until Jack looked behind the JTF soldier and took a shot to the head as James saw his Uncle die.

James: UNCLE JACK!

The JTF Soldier got hit with the butt of an AKM, as a Female BT Soldier tries to kill him but he was saved by James as he fights her and he manages to get the 93R from her hands and shoot her with it.

JTF Soldier: Thanks. Sorry about your uncle. We gotta go.

James: Looks like she's got a note on her.

James checked the Female Soldier and found a folder with some kind of project inside.

James: What the hell...? ISAC, identify this.

ISAC: Project Identified, Project Seafighter.

James: S**t. Private Bronson, get to cover. *grabs an M60* Take this.

Pvt. Bronson: What do I do with this?

James: Keep yourself safe. Bring this to Agent Kelso, I'm keeping these assholes off of us. And take her for interrogation.

Pvt. Bronson: Yes, Agent. I'm gonna have fun.

James: Yeah, no problem. Take Project Seafighter with you and give it to Kelso. Remember that.

They go out as the Black Tusk get gunned down as the JTF Guardsman fires the M60 and James carries the Wounded Female BT Soldier as a Humvee arrived but the Black Tusk who got out were killed.

James: Get in that Humvee!

Pvt. Bronson: What about you, Agent James?

James: Mark, go without me. I might have to keep them off.

The JTF Soldier was Private Mark Bronson, and he is seen running to the Humvee as James covered him. Then he drove off to the White House as he watched hopelessly as a Grenade exploded just near James.

Mark: Dammit.

Mark arrived at the White House as he got out and ran to the White House and called for Agent Kelso.

Mark: Agent Kelso?

Agent Kelso: Yes, what is it?

Mark: JTF Private Mark Bronson, reporting about a Project Seafighter given to me by Agent James MacLellan.

Agent Kelso: Where is it?

Mark: Here it is, ma'am. And I brought a guest with me.

Mark guides Kelso to the Humvee as he opens the rear passenger door as Kelso gives him a Thumbs Up.

Somewhere unknown...

James was seen as he woke up on the deck of an aircraft carrier.

James: Well, this is awkward...

James looked around, and he noticed that he was on the same ship that his father was in. And he touches one of the F/A-18E Super Hornets.

James: ISAC, where am I?

ISAC: Location: USS Nimitz, CVN-68.

James: Who was a notable Marine in the Nimitz?

ISAC: Notable Marine, Major David Martin K. MacLellan.

James: Holy s**t. *yawns*

ISAC: Agent Status: Sleepy.

James: Thanks for the status, ISAC. I'm going to the quarters.

James heads onto the Living Quarters as he sleeps soundly.

In the morning...

???: The truth is... War never changes. It's exactly the same, no matter which era it happens upon.

It shows old ships with cannons as the narrator continued.

???: The age of Discovery. Humanity sets sail to oceans unknown, hearts hungry for adventure. But soon, those hearts were filled with a desire to Conquer The Seas. 

The screen turned black.

???: Unfortunately, a new enemy appeared, hailing from another world.

Some battleships were seen until portals appeared as unknown vessels had landed into the ocean and then what looked to be girls, with the cannons of the Battleships, sinking the two fleets.

???: The Sirens.

It later shows a group of sirens firing their main guns.

???: With their vastly superior technologies, the Sirens effortlessly pushed humanity out of the oceans. There was no longer any place in the Seas for mankind. To counter this extraordinary threat, humanity organized a global alliance. It was called Azur Lane. Their objective was to fight Valiantly against the Sirens. This Grand Alliance consisted of four major camps. They are Eagle Union, Royal Navy, Iron Blood, and Sakura Empire. 

It now shows two Shipgirls fighting the Sirens.

???: After a prolonged and desperate struggle, Azur Lane was successful in repelling the Siren onslaught. Which brings us to the present day.

 After that, two Dive Bombers started flying on the skies, and what lies on the sea is an aircraft carrier.

Waters adjacent to Eagle Union homeland...

Vestal: Is everyone here ready for departure? This could potentially be a dangerous battle. Please use caution.

Enterprise: The most important lesson in history is... New eras may begin, but war never changes.

Location: USS Nimitz Living Quarters

James woke up as he went up to the deck as later on, he saw the US Navy Insignia get replaced by the SHD Logo.

James: Damn, probably this ship should be Special Homeland Division Ship, or SHDS Nimitz.

He later saw an F/A-18E Super Hornet take off as a UH-1Y Venom starts to lift off with two more following.

James: Huh. Wonder where they're headed.

That's when a Drone comes back as he checked the footage and he went into his ship form as he formed his M4A1 and when he arrived, he saw a giant fox and it was about to attack a Shipgirl, until he blocked it with the Bulwark Shield.

James: You okay?

It shows Kaga looking at James, very shocked and confused.

Kaga's thoughts: Who is he? His accent, he could be from Eagle Union, but that patch... Where is this carrier from?

That's when James pulled out his X-45 and fired three rounds at the Fox as it Collapsed as three bullet holes were seen on the face of the fox as James flipped the bird on the corpse and he grabbed his M4A1 and the Super Hornets, Venom Hueys, Ospreys, F-35Cs, and other aircraft started covering him.

Cleveland: Those Aircraft... They're like Siren Planes, but they're not attacking us. Who is this person?

A6M Zero Fighters try to damage James, but the Phalanx CIWS Emplacements and the F-35C and F/A-18E Super Hornets are shooting them down. Until Enterprise arrived and started helping the Azur Lane ships, and she shot Kaga with her bow until James went in and fired a burst from his M4A1. Akagi and Kaga retreated for now. As later on, it shows James deactivating his shield. As Wales touched his shoulder.

Wales: We need to ask you some questions, is that fine by you?

James nodded as it showed him sitting on a couch with the Royal Navy Ships and Eagle Union Ships.

Illustrious: So who are you?

James: Agent James MacLellan, Special Homeland Division.

The shipgirls all got confused, so he decided to use his ship name and then his real name.

James: Just to reduce the confusion, I'm USS Nimitz or James MacLellan.

Cleveland: We noticed that patch on your right shoulder, and can you explain what that is?

James: Remember when I mentioned "Strategic Homeland Division"? I'm part of it.

Everyone was confused again, but everyone heard this from James.

James: The Strategic Homeland Division, or simply, "The Division," is a classified force of Highly-trained and self-supported agents like me. As in other words... I'm from another world.

Everyone was speechless and oddly enough. He said this.

James: ISAC, can you tell them my full identity?

ISAC: Name: James Lockhart T. MacLellan. Age: Twenty-nine. Occupation: Division Agent.

Illustrious: Who is that speaking?

James: This is ISAC, or Intelligent System Analytic Computer. He's the AI used by every agent.

Wales: Everyone?

James: Everyone. Currently, I was in Washington DC, as I was in a Harbor, as we were fighting Black Tusk. A contractor is one of the facts we fight in our world.

Everyone had stopped giving him questions, and they assigned him to the Eagle Union as later on, it shows James going down the Harbor, already out of his ship form.

James: What a damn mess they made.

San Diego: LOOK AT MY SHIP! (CRYING)

James: Bastards. Hey Cleveland, do you need any help?

Cleveland: Nimitz, I've got it!

James saw Enterprise, and she almost fell, but James caught her.

James: You should not be endangering yourself, Enterprise.

Enterprise: It's fine. You don't need to worry

Enterprise looked at James, and she went away as James went on and saw Javelin and Laffey as he went there.

???: She okay?

Javelin: She's always like this.

???: I see.

Javelin: Not a good place to take a snooze.

???" No kidding. She should be in a bed.

Javelin: And you're-

James: Division Agent USS Nimitz. ISAC, can you state my real name?

ISAC: Agent James MacLellan.

Javelin: Nice to meet you, Nimitz. I'm Javelin. She's Laffey.

James: Greetings, you two.

Laffey: *Sleepy* Hi.

James: Who was that kid with the unicorn?

Javelin: Oh, that's Unicorn.

After that, three shipgirls came.

Unicorn: Hi Javelin, hi Laffey!

Javelin: Hey there, Unicorn, are you alright? Are you hurt?

Unicorn: Mm. I'm fine. Thanks for asking, who is he?

James: *chuckle* Hey there.

Unicorn was a bit nervous and went behind Illustrious.

Illustrious: Sorry Nimitz, she's a bit shy.

James: But she knows I'm on her side, right?

Illustrious: Yes she knows that.

James: Hey Unicorn, remember when I blocked an Attack with my Shield?

Unicorn had remembered it, until James heard something drop as he covered his eyes.

James: YO WHAT THE F**K? I DO NOT WANT TO SEE THAT HAPPEN!

James had walked away slowly as he later sat on his ship and he got down and went out of the Carrier as Enterprise noticed the Nimitz-Class Carrier.
