At somewhere, At the waters adjacent to the Azur Lane's base...

A destroyer girl, donned the white hair, cat ears and a maid uniform. Hamman, is on her way to the Base in panic... The others... 

Northampton: Hammann, calm down...

Hammann: Are you kidding!? How can you expect me to calm down, when the entire base is attacked right now!?

Helena: Because, we've just told you that the base reported, that the enemies have already been repelled.

But, her stubbornness endures... 

Hammann: WE HAVE TO HURRY!!!

In Haste, she charged again, splashing water at Helena and Northampton.

Northampton: How is she so energetic? She's been like this yesterday...

And...

Long Island: This ghost is exhausted... I need some shuteye...

Arizona: Thank goodness, that the enemy was at least pushed back. I heard it was Enterprise and the Unknown Battlecruiser who did it.

Northampton: Enterprise...? Wait... Hornet, isn't that your...

Hornet: My sister. Yeah, I guess it's a bit annoying being related to a champion. Hehehe...

Hamman turned around...

Hammann: Hey! The enemy can show up and any moment! Less chit-chat and let's get focused!

Hornet: Right! I suppose, Hammann does have a point, it really would be in our best interest, to hurry the party along!

As they're coming, Helena heard something with her radar.

Helena: !!! *Turns to her Allies* Everyone, listen!

Arizona: What's wrong, Helena?

HCM (Nick): I suppose that's the 5th Carrier Division...

They've spotted the 5th Carrier Division of the Sakura, heading to them.

Hornet: Well darn, I guess, we were too slow.

Helena: Sakura Empire's Carriers...

Long Island: Ehhh... They look strong...

Hammann: We're staring at a bunch of bathtub tugboats! Let me handle these goons!

Hornet just stared, at the two carriers.

Meanwhile...

Shoukaku: *fake moan* I feel so faint... How could the superiors, be so mean and bully me like this... I didn't do anything, right, Sweet-kaku?

HCM (Nick): Pfttt... Sweet-kaku? Really? *Laughs*

Zuikaku: S-S-Screw you, Nick!

At the next carrier... It's Zuikaku, she's wasn't impressed by her elder sister's antics.

Zuikaku: You really shouldn't take it so personally, big sis. Besides, we have a good opportunity here. The First Carrier elders will  finally see our strength.

Shoukaku: I see.~ I admire the way you're always thinking ahead, Sweet-kaku.~ And I'm giving you my word that I'll always have your back, no matter what!~

Zuikaku got into her position and took out her katana.

Zuikaku: Heh! Then as long you're with me, I've nothing to fear!

Back at the Azur Lane Base.

Wales: We have to go help Hornet and the others! Which ships are ready to move out?

Illustrious came in, and warned Wales.

Illustrious: There you are! Both Nick and Enterprise have spotted something wrong!

Wales: What is it!?

Illustrious gave the note that HCM gave to her.

Glory to Vietnam and the Motherland (Russia).

To Wales.

"I'm currently heading to the detachment forces to rescue them. Estimated arrival is 2 Mikes at South East Sector. May God and Saint Andrew bless you."

From, Son of Saint Andrew.

Wales: What!? How!?

Illustrious: His helicopters...

Meanwhile, at Nick's and his Squad.

They're now sailing to the Detachment forces, HCM (or Nick) is praying to god while sailing with them. Enterprise riggings are showing signs of deteriorating.

HCM (Nick): Oh Saint Andrew... May Enterprise last the hostile's assault, with your blessing...

Cleveland: Enterprise, wait! You're going to far ahead!

Enterprise: Slowing down is a waste of time!

As she said it, she's struggles.

HCM (Nick): God damn it!

Nick got her.

HCM (Nick): I told you! You can't fight like that, when you're gravely damaged! You should've rest and fix your ships properly!!!

Enterprise: What do you know... Hornet's my sister, I have to!

Cleveland understands, but Nick, is not taking any chances. Enterprise continued, without Nick's help...

Cleveland: Oh, I understand...

HCM (Nick): *sighs* Karma is going to make you pay, Enterprise...

Cleveland: I mean, it's great to see Enterprise have a human side, Nick. Aren't you too?

HCM (Nick): Her recklessness is going to be her downfall... Why wouldn't I be worried about her?

Cleveland: Well, in that case, let's do this!

HCM (Nick): *sighs again* Very well...

They followed Enterprise...

Cleveland: I have many sisters, myself. So, I know how do you feel.

HCM (Nick): If only, my little sister Pyotr Velikiy and my old friend Carl Vinson is here...

Cleveland: I just wish we have some escort vessels to back us up, you know... Wait... You have a little sister?

HCM (Nick): Yeah... She's still in the Russian Navy and still alive when I last see her... I really miss her though...

Laffey and Javelin came from behind them.

Laffey: I wanna help you too...

Javelin: Same here! We've quite a team!

Both Nick and Cleveland turn to see them both, Cleveland with a thumb up, while Nick with a faint smile.

Cleveland: Let's do it!

HCM (Nick): I have high hope for you two, Young Javelin and Young Laffey!

Back at Hornet's...

Things are not going well for the Eagle detachment forces. Hammann was knocked out, Long Island is out of commission, Arizona got Pearl Harbor'd, Helena's Radar couldn't save herself and Northampton is barely floating... Only Hornet is still standing and evading the Bombs.

Shoukaku is playing with her flute, sending more planes at Hornet.

Shoukaku: This melodies is a requiem, it's purpose is to bring peace to the dead.

She continued, with more planes forcing Hornet to stay evading...

Hornet: It's not fun, being on the defense! Can I get some back up!?

After a few successful dodge... Hornet is about to meet her maker...

Zuikaku: I've got you!!!

Hornet: Oh... Damn...

Until...

HCM (Nick): Halt! In the name of God!

Four of Nick's Shipwrecker Missiles and three Hellcat's engaged Zuikaku, saving Hornet in a nick of time. 

Zuikaku: What the!?

Zuikaku was able to block the bullets and missiles, but a fourth one got her.

Zuikaku: ARUGH!

Shoukaku turns to the rescuers, she noticed Nick.

Shoukaku: So... That is the Son of Saint Andrew...

Hornet: When did you get here!?

Enterprise: Go on!

Enterprise continued to attack Zuikaku, Nick just...

Hornet: And who are you!?

HCM (Nick): Son of Saint Andrew. Now go!

He left Hornet alone too.

Hornet: Wow... Thanks.

Nick went after Shoukaku, while Enterprise goes for Zuikaku.

Zuikaku: Gray Ghost, I knew you would've come!

Zuikaku, went at Enterprise, Bow against a Katana, While...

HCM (Nick): FOR GOD AND THE MOTHER RUSSIA!!! URRRRRRRRRRAAAAAAAAAAAAAAA!!!

Shoukaku: Wha-!?

Nick sent missiles after missiles., at Shoukaku, hitting her.

Shoukaku: Argh!

HCM (Nick): I'll make sure, you'll pay for your treason from the lord!

Zuikaku: If it isn't the Eagle Union's strongest Carrier, you're a worthy opponent for me!

Enterprise pushed Zuikaku away.

Zuikaku: Heh. Ready? It's time for us to duel!

Both Enterprise and Zuikaku got their weapons ready. While Nick stopped attacking Shoukaku... Shoukaku got confused, why he stopped.

HCM (Nick)'s Mind: Wait a minute... Something's not right...

Hornet was able to reach to Cleveland.

Cleveland: Hey there, Hornet! We're here to help you!

Hornet: Nice timing, thanks. I was starting to get a bit nervous...

Hornet nearly collaped, but Cleveland able to catch her.

Cleveland: This is our chance to come back, give me a second to bring out my ship.

Lucky for them, Nick spotted Eugen, thanks to his Paranoia.

HCM (Nick): Print Eugen! I challenge you to fight me!

The girls was shocked, how he was able to spot Eugen and challenged her to fight Nick.

Hornet: IS HE OUT OF HIS MIND!?

Cleveland: Are you crazy, Nick!?

Prinz Eugen: Vell zhen, zince you asked.~ FEUER!!!

After firing at Nick, he was able to dodge her attacks, with the help of his CADS-N-1 CIWS and backflipped for a SVD trickshot... Her Riggings.

*BANG!*

A Perfect hit for the marksmen.

Hammann, Arizona, Northampton, Helena, Hornet, Cleveland & Javelin: EEEEEEEEEEHHHHHHHHHHHHHHHHH!? 

Prinz Eugen: VHAT!? HOW DID YOU-!? WOAH-!?

Eugen nearly falled to her demise... Only for Nick to catched her, in time.

HCM (Nick): Jesus Christ... Sorry about that. I didn't know that helped you fly...

Eugen could only blush... 

Prinz Eugen: U-Umm...Can... can you p-put me d-down...? You could've hurt your arms or back... But s-still... Zhank you...

HCM (Nick): *slight blush* Don't mention it. You maybe a fascist, but... I... I kinda like you... Although... I'm not as defenseless as you've thought...

He let Eugen down, Eugen, still embarrassed, at the same time, Nimi and Ayanami came out.

Prinz Eugen: N-Nimi, can you take care of zhis...? I need to get a breather...

Z23/ Nimi: Understood...?

They both got in position. While Eugen leaves the battlefield...

Z23/ Nimi: I am Z23, a ztrong Ironblood Destroyer. You're standing on ze place of your final defeat.

Ayanami came in the same.

Javelin: No way... It's Ayanami!

HCM (Nick): ... Cleveland, Javelin, Laffey. Get the wounded out of here. I'll deal with them.

Javelin: Why...? What are you doing...?

Cleveland: That's two on one! You won't last!

HCM (Nick): I'll live. Just go.

They left Nick to his fate.

Z23/ Nimi: Zo, you're volunteering to be ze breach? Zhat's an honorable act, even by an enemy.

Nimi ready her guns, Nick has his Ak-15 ready, aiming at Nimi...

HCM (Nick): This doesn't have to end like this... *sighs* I suppose there's no choice... I'll do so until death, whatever the cost...

He put on his smart goggles and got ready.

HCM (Nick): Активируйте Ак-130... и торпеды... Код Зеленый... "Activate the Ak-130... and torpedos... Code Green..."

VMF System: Понял, пусть отец понимания проведет вас. "Understood, may the father of understanding guide you."

Nick's HUD went from [Safe] to [Weapons Ready].

HCM (Nick): Now... *Ka-Cling* Hope you say your prayers to Jesus Christ... *Turn Serious* Because it's Judgement Day!

Back at the Azur Lane Base...

Some of the Eagle Union and Royal Navy were still here, after the briefing. U-chan was eating a small cake...

Unicorn: U-chan...

The telephone rings...

Wales: Hello, Azur Lane Base Command.

???: It's been a rather long time, Wales.

Wales: Your Majesty!

Queen Elizabeth: The wait is over. I, Queen Elizabeth and my noble fleet have arrived to make everything splendid.

Which, it is. Four other ships, Hood, Warspite, Edinburgh, and Sheffield. They're having tea, while Sheffield is holding the phone for Elizabeth.

Wales (On Phone): Thank you, your Majesty. Our allies are currently under attacked...

Hood and Warspite noticed her sudden movements.

Queen Elizabeth:  Yes, I know what's going on. And I've already maked my brilliant move!

Which is... sending Belfast.

Back in the Battlefield.

On one side, Enterprise and Zuikaku are still fighting, while the other... Nick has taken serious damage, despite his armor, mostly from Nimi's AP rounds. But, he was able to turn the tide against Eugen, Nimi and Ayanami alone.

Zuikaku blocked Enterprise's arrow, and then charged.

Zuikaku: Oh no you don't!

Zuikaku managed to stop Enterprise from firing an arrow. Forcing Enterprise to block.

Zuikaku: There's more where that came from! I expected you to be stronger...

After a few attacks, she got her, and before she could get a chance...

Shoukaku: Zuikaku, please stop!

That's when she realized that... She was tricked. She was able to deflect the arrow, but it turned into a Hellcat, going danger close and dropped a bomb on both of them...

Zuikaku: NOOOOO!!!

*KA-BOOM!!!*

Enterprise, continued her assault on Zuikaku.

Meanwhile...

Nick was pushed back, but he kept fighting. He was bleeding a bit, tired and he used all of his missiles, waiting for it to reload... He reloaded his Ak-15. He looked at the other two, they were wounded. Eugen was impressed of his aggressiveness and recklessness.

HCM (Nick): *Heavy Breathing* ... I won't... go down... by you... two... *coughs*

Eugen: Oh my, he's getting weakened.

He was ready to fire at will, until...

Shoukaku: Sweet-kaku!

Zuikaku was barely getting up...

Zuikaku: I've got to hit her at least once...

Enterprise: It's all over.

That's when...

*SNAPS*

Her bow breaks... Nick spotted that.

HCM (Nick)'s Mind: Shit!

Enterprise's Mind: Why did I reached my limit now!?

Zuikaku, charged her katana with her planes and went for the killing blow. Nick rushed to Enterprise to...

Zuikaku: YOU'RE GOING DOWN!!!

Enterprise: !!!

HCM (Nick): WATCH OUT!!!

*SLASH!*

Nick saved Enterprise... by shielding her, with himself, redirecting the killing blow on Nick instead...

HCM (Nick)'s Mind: ... Father... I've failed you... I'm sorry...

Zuikaku: What!?

He rolled to the seas like if it's the ground, face down and motionless... His blood and now coloring the seas red.

Cleveland: NICKKKKKKKKKKKK!!!

Javelin: NICK!!!

Enterprise: ... N-Nick...

Belfast: Oh dear, it appears I'm too late...
