In the Sakura Empire.

Two weeks after Siren allied with Azur Lane.

Mutsu, the second and last ship of the Nagato-class battleship Dreadnought, as well as the leader of the Sakura Empire to replace the "disappeared" Nagato.

Right now, Mutsu was discussing with Kawakaze, Mikasa and Admiral Yamamoto. Warm green tea served on their small table, and Yamamoto opened the conversation.

ADM. Yamamoto : Mutsu, as we all know, Siren has left us and is now helping Azur Lane in building weapons, what is our next move?

Mutsu : (sighs) If this keeps happening, Then we will be outnumbered both in numbers and now in technology, I actually wanted to go straight to them and sign a truce, but not more than a month ago we raised the flag of war to all countries under the Alliance Azur Lane. We will only be seen as cowards and sycophants, I don't want my sister's beloved country to be like that, not if I can do something about it.

Mutsu glanced outside and saw two giant Battleships under repair due to a technical malfunction.

Mutsu : What's more the two of them.... The Yamato-class Super Battleship, the largest ship ever built by the hands of the Sakura Empire, the two of them and their sister carrier often suffer damage which erodes our already scarce logistics. What's more, all three of them were hyperventilating, for some unknown reason.

Mikasa drank her green tea and said.

Mikasa : Most likely because of the Siren, considering they have a power that all of the Empire's best scientists can't explain, but in the end, they've always kept quiet about their weaponry and abilities.

ADM. Yamamoto took a deep breath and drank his green tea.

ADM. Yamamoto : I'm still curious, how did we get this low. (massage temple. )

Mikasa : you and me same, Admiral.

Kawakaze suddenly spoke up which surprised the other three, as she was always silent.

Kawakaze : Mutsu-Sama, I have some very shocking news from our... Ironblood colleagues. They claimed to have seen a shipgirl who was very similar to Nagato-sama, the only difference being the clothes, flag and hull of the ship.

Everyone except Kawakaze, widened their eyes.

ADM. Yamamoto: What?! They say they were defeated by Azur Lane's prototype weapon!

Kawakaze : They said they wanted to make sure what they saw was really Nagato-sama, so they say.

Mikasa : Outrageous! But what do I expect, Europeans have never considered honor an important thing since.... Their Fuhrer rose to chancellor.

Mutsu stroked her chin thoughtfully, but in her mind, she screamed with happiness as loud as she could, happy to hear that there was hope that ber sister was still alive. Mutsu looked at ADM. Yamamoto.

Mutsu : Admiral, gather the fleet, we will knock on the door of the Azur Lane frontline base and of course.... Confirm whether it is Nagato or not.

ADM. Yamamoto nodded firmly.

ADM. Yamamoto : Understood!

ADM. Yamamoto stood up, bowed, and quickly gathered all the ships he could muster up in no time.

Mutsu let out a trembling breath, Mikasa stroked Mutsu's shoulder, calming her down. While Kawakaze just lowered her head, but her hands were clenched into fists.

Pearl Harbor Base.

Cleveland saw the two Siren mass destroyers and the Fletcher class destroyers, sailing and coordinating with each other. Likewise with the Siren Battleship which was conducting firing exercises together with several shipgirls and five battleships manned from EUN. (Eagle Union Navy.)

All of the Siren battleships now have a black and blue color scheme, indicating that the Sirens are on the side of humanity...for now.

Cleveland was quite surprised when several Siren transport ships landed at Pearl Harbor and unloaded their hundreds of Infantry which had the most advanced weaponry in the eyes of the humans, but as the Siren explained, these were just Light Infantry units. But she didn't need to worry too much, Nagato promised to keep every Siren asset locked in Pearl Harbor, and if they thought of anything funny, dozens of cruise missiles would hit them.

These two weeks have been full of.... Events. The truce that the Sirens and Azur Lane made, some of the Azur Lane Shipgirls started befriending some of the Siren Shipgirls, maybe this will be a bridge between the two sides, maybe.

Cleveland looks down at the beach and there are Laffey, Javelin, Unicorn and an Explorer-class destroyer Siren Shipgirl named Ciel, playing together and building a sandcastle. Nagato and Enterprise sat under an umbrella near a coconut tree, watching the little girls playing.

The world has really changed, Cleveland thought as she shook her head in Amusement, as she was about to walk away she saw a Siren Shipgirl with a blue accent, staring at the fast food truck manjuu manned. Cleveland shrugged her shoulders and walked over to the Siren Shipgirl.

Cleveland: Hey!

But Cleveland instead made the Siren Shipgirl surprised and walked backwards.

Cleveland: Woah Woah! I'm sorry if I surprised you, I was just curious about you. The Name is Cleveland, you?

The Siren shipgirl looked both embarrassed and scared, but answered.

Intruder : I am a Mark I Intruder Unit, ITR-25-22226.

Cleveland scratched the back of her neck when she heard the strange name.

Cleveland: Don't you have a nickname?

Intruder just shook her head, and Cleveland hummed as she studied Intruder.

Until finally something clicked in her brain.

Cleveland : What if I call you Blue? easier to say too right?

Intruder or now Blue, widened her eyes a little and looked very excited.

Blue : I have a name... Just like a high-ranking Executor! Uhm... Cleveland, right?

Cleveland nodded enthusiastically.

Cleveland: Yep! Want to hang out? at the same time getting to know my sister? Ah! but i see you staring at that fast food truck all the time, you wanna try?

Blue: Really? Thank you!

On the beach.

Nagato took a deep breath, she was still wearing the same clothes as yesterday, but this time she was wearing a Hawaiian t-shirt. While Enterprise wears a swimsuit that is quite revealing.

Nagato : Prise, should you really wear that?

Enterprise : what do you mean Nagato? this is a beach, of course we have to wear such clothes.

Nagato : You mean, unfinished clothes?

Enterprise smiled quite proudly of her assets, she made some sexy poses that made Nagato take a deep breath, and glanced over the bushes where three Siren Infantry and three Eagle Union Marines were in.

Nagato : Haaaah.... Man.

Enterprise: huh? Why?

Nagato smiled bitterly and continued to watch the little girls build a kind of Buckingham Palace with several dozen toy guards which were quite interactive.

Nagato : The less you know, the better.

Enterprise had a comical question mark icon above her head like a character from a cartoon but she shrugged her shoulders.

Javelin : Wow, this looks like real Buckingham Palace!

Unicorn : Right, Javelin!

Laffey : sleepy....

Javelin : But Ciel, you're really good at infrastructure, huh?

Ciel, a Mark-II Explorer-class Siren Shipgirl smiled happily.

Ciel : Thank you, Javelin! I always like to learn about buildings in my spare time at the workshop.

Unicorn : Uhmm... what are you doing there?

Ciel: Hmmm? Of course, getting repaired, upgrading Equipment and so on, what do you think at first?

Javelin : Hehe... maybe our imagination is a little wild.

Unicorn blushed while scratching her cheek timidly. Meanwhile, Laffey, she decided to overhaul the formation of the toy guards who for some reason turned into typical clothes during the American Civil War.

Laffey :..... For the country! Present Arms!

All the Guards in American Civil War uniforms aimed their Muskets as well as ball cannons at Buckingham Palace.

Javelin : Wait- Laffey Don't!

Laffey : Fire!

All the toy guards in American army uniforms during the Civil War shot directly at the Guards in Royal Guard uniforms guarding Buckingham Castle, sending them flying and destroying the front wall of Buckingham Castle.

Ciel: Aaah! My castle! Javelin, Unicorn, let's avenge what this Union rabbit did!

Javelin & Unicorn : Got it!

Javelin took out a medium sized box and took out hundreds of live toy soldiers and immediately opened fire at the Laffey Soldiers who were surprised because what Javelin took out was an Second World War soldier, complete with Churchill Heavy Tank and some Shermans doing support fire.

Laffey : You girls are cheating...! How did you girls get that set?!

The three of them laughed darkly.

Javelin : Technology, Laffey!

Unicorns: they are growing as they follow the Ages.

Ciel, Javelin & Unicorn : You can't beat us, Laffey.

(guess the reference~)

Laffey : Ugh... Aunt Nagato! They bullied me!

Nagato slapped her forehead as Laffey complained to her, while Enterprise burst out laughing beside her.

Nagato : stop being irresponsible.

And Nagato look at the War torn.... Sand castle. She can see dozens of Continental soldiers desperately holding off the offence of the more more advanced soldiers.

Nagato : W-Why is the fight scene like the Wattpad fanfic that my crew read in my old world....

Enterprise : Wattpad? What kind of Fuckery is that?

Nagato : Like I said before, the less you know, the better.

Enterprise pouted.

Enterprise : Oh come on, Nagato. I'm curious about an alternative future!

Nagato rolled her eyes, and took out Oxy Cola from the ice box they brought with them.

90 kilometers from Wake Island.

The five Essex class mass production carriers are escorted by 12 Fletcher class mass production ships, 3 Baltimore class heavy ships, 2 North Carolina class mass production battleships and several supply ships.

Aboard one of the mass-produced Essex-class aircraft carriers, the USS Trafalgar, a captain by the name of John F. Kennedy was looking at the ships in his fleet. He felt quite proud to see Eagle Union's industrial strength had not changed at all. But there is one thing that is the source of the problem, there are three Siren Fleet warships who are providing them with screening support.

The entire crew in the fleet he was leading were tense and they had secretly loaded their cannons with shells, if the Sirens thought of doing something funny they would open fire. But hopefully that doesn't happen.

Kennedy saw one of the warships that became the flag of the Sirens, the Mare Nostrum. This 600 meter long giant warship carry a very.... irresponsible weapon. 5 triple barrel 510mm gun turrets, hundreds of plasma anti-air guns, dozens of secondary cannons the size of a Baltimore cannon, all in all, the Mare Nostrum is a very mean looking ship. luckily the color scheme is blue and not Red.

Not only that, their shipgirls is here made all the crew even more nervous.

Kennedy: Absolutely amazing.

said Kennedy as he drank the coffee one of his crew brought him.

?? : Indeed, captain.

Kennedy looked back and saw an old man in a dark blue navy suit with gold accents.

Kennedy held out his hand, and the old man shook his hand.

Kennedy: Quite happy to know the fact that the Sirens saved someone as great as you, Fleet Admiral Steven Hackett.

FADM. Hackett smiled faintly.

FADM. Hackett : Nice to meet you too, Mr President-I mean, Captain.

Kennedy raised one eyebrow but decided to shrug it off.

Kennedy : Admiral, can I get an idea of ​​the enemy we will be fighting?

Hackett's eyes darkened and he clenched his fists.

FADM. Hackett : They... the Leviathans are cunning foes. Possessing an arsenal that surpasses even all the races in my world, more than trillions of souls were lost when the Leviathans started… consuming my Timeline. Nothing was left, not even dust left.

Kennedy who heard that shivered, as did some of the observation crew who were near them.

FADM. Hackett : Until finally the Sirens arrived to save me and some of my crew from the SSV Kilimanjaro, since then I have joined and worked for the Arbiters. Captain, if we are to destroy all the Leviathans, you and your Men must be able to cooperate with the Sirens, trust them. They will help you as best they can.

Kennedy pondered Hackett's words and saw a sinister-looking woman with pure white hair, pale skin and golden eyes emerge from behind Hackett.

Kennedy reflexively grabbed his service gun and the Woman just snorted in amusement.

??? : No need to be too surprised Human, I just wanted to see Admiral Hackett.

FADM. Hackett : That's okay, Rosemary. It wasn't even two weeks ago that they made an alliance with you. And this is also a kinda your kins fault you know.

Rosemary, a high-ranking Siren shipgirl of the Tester class just waved her hand lazily.

Rosemary : Fine.... Admiral Hackett, the battlefleet led by Lord Hood will arrive at this timeline in 2 hours, he also brought Kilimanjaro with him.

Hackett smiled hearing this.

FADM. Hackett : Perfect, Captain, where have we been-

Suddenly one of Fletcher's mass-produced ships, the USS Jim Carry, exploded due to a concentrated purple light from beneath the sea.

Hackett and Rosemary were surprised to see the purple light.

Rosemary: Oh no....

FADM. Hackett : They're here.... All hands, battlestation! (shouts over the radio.)

Kennedy : Men! I want all the planes on this ship, in the air now. Give me every report, and where's the goddamn submarine escorting us?!

Radar officer : We didn't detect our submarine sir! But.... something big started to rise to the surface of the water.... 5...4...3...2.... It appeared!

A big explosion of water occurred causing the waves to be big enough to make all the ships present tossed about by the waves.

The USS Trafalgar, carried by the waves and crashed into the USS Tempest, a mass production ship of the Baltimore class. Several crew members were injured in the incident and the hull of the Trafalgar was damaged and water began to enter the ship.

But that's not what Kennedy's main concern is, now in front of him, there is a creature that is very... Beautiful and terrifying at the same time. With a length of more than 3 kilometers, the creature also carries a giant cannon that is very much all over its body. two carrier decks on the starboard and left hips, Dozens of VLS cells with state-of-the-art guided missiles. The giant ship's bridge lights up in purple and emits a strange neon sign with purple over its 'head', it looks like Halo angel.

What made all of the Eagle Union crew pale was the size of the creature and its escort. Dozens or even hundreds of battleships with black shells and emitting a terrifying purple glow.

The creature that looked like a western dragon looked at everything in front of it, and roared loudly.

SKREEEOOOOONNNHGGHHHHGGHHHHHHHGH

As loud as the creature's screams were, the shockwave shattered every glass on the Eagle Union and Siren ships. Even the antennae of their destroyer fell off and flew off and hit several ships.

Humanity's first battle in this timeline against the void has begun.
