The day was the same as usual, bright blue sky, the warm breeze of the wind, and the sounds of the wave. But all of this calmness would be shattered by the loud whistling sound of a shell making its way to the base.

*Boom*

Wales: [looking out to see the sirens attacking] The Sirens?! Intercept them! This is not a drill!

Random ship girls: Yes Ma'am

Cleveland rushed hastily to the window, she then saw multiple explosion that was caused by the Enemy shelling the dockyard. In anger she grabbed her white clock and rushed to the battlefield.

Wales: Why are the Sirens attacking us now? This has to be one of the worse timing. Coincident or not.

Illustrious: I know...

Cleveland was rushing towards the docks where all the action is unfolding. Two Siren Jets then dive down from sky and unleash a busts of machine gunfire, but ultimately fail to hit a single bullet of Cleveland.

Cleveland: Cleveland, Knight of the sea.... Engaging

Her ship then turned into hundreds of mental cube and was redirected to her, equipping her with her ship girl battle equipment. Cleveland saw a siren jet targeting her and in response she aimed her main guns at it and destroy it with an accurate salvo.

Cleveland: How's that?! We where developed to be humanity's ultimate weapons to combat you sirens!

A Siren jet fired a missile which Cleveland swiftly dodged. She then returned fire with her own main guns.

Cleveland: All of us. Every single one of us has the same abilities of the strongest warship embedded in our bodies.

Soon the rest of the ship girls then equipped their battle equipment and started engaging  the enemy jets.

Cleveland: this is our power... powerful enough to defeat you!

Soon Javelin and Laffey arrive on the scene.

Javelin: Javelin going full power!

Laffey: All system ready.... engaging.

both of them fired their main guns and the two siren jets burst into flames and crash down into the blue sea. it was an outstanding success for Azur Lane as they manage to repel the siren attack. 

Javelin: Alright!

Cleveland smiled as she heard some cheering coming from the ship girls. but from the corner of her eyes, she saw a pink flower petals falling past her face. Then more pink flower petals then soon fall from the sky, most of the ship girl stare at the sky in awe as more the pink petals keeps falling from somewhere.

???: It true.... We where made by humanity to fight against the sirens.... but a difference in our beliefs splits the 4 major faction into 2 separate factions.

???(2): One faction limit themselves to only using powers created by Humankind, Eagle Union and Royal Navy fights on this side.

???: As for the other faction...

Two aircraft carriers broke through the swarm of Sakura pellets, as the ship came into view an emblem could be found on the front of the ship.

Cleveland: [Shocked] I know that emblem! 

???: This Faction uses siren technology to defeat the sirens.... Iron Blood and Us.... the mighty Sakura Empire.

both of the fox ship girls grinned as both plane from both carrier take off to the sky. the Aircraft fly around the carrier showing of their air power.

???: Sakura empire 1st carrier division, Akagi

???(2): Sakura empire 1st carrier division, Kaga

Akagi/Kaga: Behold and Tremble!

Akagi's and Kaga's aircraft started to attack the opposing Ship girls, launching bombs, torpedo, and machine guns fire attacks. Azur lane's ship girls tried their hardest to fight them off but one by one they would fall to the overwhelming power of Sakura empire's Aircraft.

Javelin: There's no end to them!

Laffey: We could be in big trouble.

 Suddenly a squadron of Supermarine Seafire F.XVII ,(A/N: I think), intercepted the incoming fighter planes.

  Cleveland: [shocked] Interceptors?!

Cleveland looked to the side to see Unicorn wearing Aircraft carrier equipment.

Unicorn: Stop bullying my friends right now!

Then U-chan transformed into a real size horse with the wings and horn of a unicorn whiles Unicorn riding U-chan on it's back. 

(Author: [Visible confusion] How?! How the Fu-)

Unicorn continues to launch more planes from her decks, her plane quickly find themselves a target and took them down.

Kaga: She appearance to be a carrier? Such a lean... She's may mot be much of a meal but... a prey is a prey.

Kaga held out her fox mask which erupted into a blue flame. soon her ship burst in a massive swarm of Sakura petals as the ship transform into a Gigantic, Blue, nine-tailed fox.

(Author: [Visible confusion] Really how?! What kind of logic is this?!)

the Fox gave out an intimidating, loud roar, giving many of the ship girls a fright, including Cleveland.

Kaga: Now sweet angel... come here.

The Fox the expanded its decks and launched more planes and attacked Unicorn. Unicorn saw this coming and attempts to flee but the planes are catching up to her.

Javelin saw this unfolding from the grown and in anger she readied her javelin and prepare for a powerful strike.

Javelin: Oh no you don't!

Unknown to Javelin, Three torpedo was launched at here but luckily Laffey spotted it  just in time and ruched towards Javelin

Laffey: Watch out!

 Laffey knocked Javelin away with some force to make ensure that javelin is safe. unfortunately laffey was in the torpedo strike zone and seconds later the torpedo detonated.

Javelin: Laffey no!

Once the smoke had cleared, Javelin could still see Laffey standing.

Laffey: [cough] [cough]  Don't worry... I'm still functioning and combat capable.

Javelin gave a smile in relief then she turned to the attacker, but to her shock it was that girl that she met from before.

Javelin: It's you!

Ayanami: Sakura empire's improved Fubuki class destroyer, Ayanami. 

Ayanami grabbed her sword from her scabbard and change at Javelin in full speed. Javelin manages to blocked Ayanami's attack just in time.

Ayanami: Taste the power... of the Demon!

Javelin: Demon? But why!

Ayanami: Because... We're enemies. Obviously.

Ayanami pulls out her main gun and fired but to no success as Javelin back flipped out of the way. 

Meanwhile, Unicorn is still battling Kaga's giant fox. she desperately launched some of her aircraft trying to kill the beast but to no prevail as the fox released multiple blast of blue flames at her. Laffey could only watch as she is too injured to do anything.

Kaga: I have to say... I'm very disappointed, I was  expecting a challenge

Akagi: Fufufufufu..... You're loving this Kaga. Aren't you?

Meanwhile with Ayanami, she launched her torpedoes at Javelin, but yet again she dodged it by jumping onto a ship.

Javelin: Please stop! If you keep going! Unicorn would be....

Sweat dropped on Ayanami's face as she know what exactly is going to happen. but for unknown reason it makes her feel guilty. Then the blue flame made contact with Unicorn, causing a great explosion to occur in mid-air, this shocked everyone.

Unicorn landed in the water with U-chan on her stomach. She then looked at the gigantic beast walking straight towards her. She closed her eyes in fear as the beast when forward to devour her.

Cleveland: UNICORN NO!

Unknown to everyone below, a lone EA-18G Growler was orbiting the surrounding airspace. Originally it was tasked to jammed all the enemy radar so Enterprise could get close enough to engage.

Alpha 0-6: Head Hunter, I've got visual on a large fox barring a flower emblem attacking a lone individual below.

Albin could see everything unfolding thanks to the camera from Bravo John, he checked how far Enterprise is out there so he could perform something neither stupid or heroic.

Albin(from radio): Alpha 0-6, you have permission to engage the fox, it's hostile

Alpha 0-6: Alpha 0-6 copy, launching AGM-88.... FOX 3!!!

The EW Aircraft launched Its air-to-ground missile at the fox below

*BOOM*

the missile explode on top of the fox's head causing the beast to roar in pain, but that's just the start, the next moment after that a blue arrow penetrated the fox's chest. The Arrow then transformed itself into a Douglas SBD Dauntless Dive-Bomber. 

Akagi: [Shocked] NANI??!!

Akagi and everyone else looked to the far distance only to see a lone aircraft carrier, but in the bow of the ship she saw a girl with long white hair, who is wearing a Admiral's cap and a oversized admiral coat. 

With Albin

Albin smiled as he saw Enterprise and her ship had made it to the base in one piece on his phone.

Albin: Hehehee... Go get them, Big E.

Two WE-10 then was launched from the steam catapult passing Albin as he looked up to the skies to see he own squadron of aircraft in the air.

Albin: Time to crash the party!

 Back at Azur Lane base

Cleveland: Wait... Could it be? 

Akagi: An Eagle Union Carrier? Is that who I think it is?

Four more dive-bomber was then deployed from the Aircraft carrier and charged toward the base.

Cleveland: I knew it was her! that's Eagle Union's strongest Aircraft carrier making a surprise appearance!

Akagi: I never predicted to see you out here... Grey Ghost.

Akagi (though): How did she bypass all of the siren's radar?!

Kaga: That's her... Enterprise.

Enterprise: Enterprise.... Engage.

Her ship then turned into hundreds of mental cube and was redirected to her, equipping her with her ship girl battle equipment. Enterprise then jumped on one of the Dive-bomber and ride towards the base. The Dive-bomber dodged the laser from the Siren ships but some was shot down. Enterprise's Dive-bomber managed to break through the siren's defence and into the base, she then made her way toward Kaga.

Kaga: Impressive! 

Kaga throws a few blue Sakura petals at Enterprise which transformed into a fighter plane. In response Enterprise fired an arrow which split into ten smaller arrow.  Only managing to take down three aircraft, she jumped off her plane and started to melee Kaga's planes. Everyone was staring in awe from this action alone.

Javelin: Amazing...

As Enterprise landed back on her dive-bomber but the giant claw of the downed beast manages to reach her. Luckily Enterprise jumped of just in time before the beast destroyed the plane and fired three of the arrows at the beast. Her arrow turned into Bombs, the bombs them exploded on the beast's head. she then landed on the deck of the beast and charge towards Kaga.

Kaga: I glad you've showed up. Before it was boring but not it's getting fun.

Akagi: Sister, restrain yourself at once!

Kaga obviously ignored her sister and launch her blue fireball at Enterprise which she blocked with her bow. Enterprise jumped up and aimed her bow point blank at Kaga

Kaga: enterprise....

Enterprise: You're through!

Enterprise then shot Kaga directly in the middle of the chest.

Akagi: Kaga!

After that attack, Kaga's giant Fox beast disappeared.

Kaga: How dare you... this body belongs to my sister!

Akagi: Sister don't!

In anger she launched four planes at Enterprise. but to everybody surprise they all exploded mid-air. 

Kaga: What?!

Then she saw three incoming aircraft diving down towards her, she quickly send some fighter to intercept them but to no success. then the three aircraft opened fire on Kaga.

*BBBRRRRRRRTTTTTT*

Kaga screemed in pain as the aircraft pulled back up to the sky. Suddenly a WE-30 flown pass all of the ship girls below, a person then jumped off the aircraft and landed next to Enterprise.

???: Sorry I'm late Big E. What've I miss?

Enterprise: Took you long enough.

The ship girls are shocked to the very core, because right in front of them was a boy... a Ship boy!

Albin: the name's Albin! Albin-class Supercarrier, reporting of duty.

His introduction was cut short by the sounds of explosions from the background. It was his WE-10 and F-35 destroying the sirens fleet.

 Kaga: Supercarrier? You actually though we'll fall for that?

Akagi: Enough Kaga... 

Kaga: But sister! i could still fight!

Akagi: I know but we have some unexpected visitors... But there's always a right time for everything.

Then a bomb of a plane and a salvo of shell struck the siren ships and begin to be bombarded by both of Wales and Illustrious.

Unicorn: Big sister!

Cleveland: Dam, you're very slow today.

Akagi: [holding a Black mental cube] We've achieved our goal, but most importantly the operation was a success.

Kaga: I see... I understand Dear sister.

Enterprise: [Aiming her bow at Akagi] Just where do you the you're going?

Akagi: Ara~~ your voice is so tense, I think I'm going to pass out in intimidation 

Then out of nowhere a red sakura petals knock onto Enterprise's hand, knocking her off her aim. Enterprise looked to the far distance to see another Sakura empire's Aircraft carrier, it was Zuikaku.

Zuikaku: My senior, shall we get going.

Akagi: Agreed. Our work her is done.

All of the Sakura Empire's ship girls started to withdraw from the base.

Enterprise: Cowards!

Akagi: Azur Lane, consider this a formal declaration of war

Kaga: We, the Sakura Empire have joined forces with Iron Blood to cripple your little alliance.

Then a storm of Sakura petals surrounded Akagi's and Kaga's Aircraft carrier.

Akagi: They say the Strong rules over the weak... the mighty welds the most power,, and power controls the future... Heaven is on our side... we are the true conqueror of the sea... We are the alliance of the Crimson blood... we are Red axis...

Albin's radio: Head Hunter, Bulldog 3-3 here. Enemy ship is in retreat how should be process over.

Albin: The battle's over, all planes RTB. [to Enterprise] Hey, we'll get them next time. [gently elbows Enterprise in the arm.

Wales: They managed to escaped, but I'm grateful to enterprise and that boy for saving us.

Illustrious: They really have saved us, Enterprise and that boy, who ever he is....

Albin: [looked around] Yikes! So much of a newly constructed base. now you got to start back from square one.

Enterprise took no notices to Albin's comment 

Enterprise: [muttering out loud] One battle ends, but soon another would begin....
