This is a collab between me and HoshidanWolf

September 11th, 1963, at the naval base of Pearl Harbor on the island of Oahu, Fleet Admiral Arthur Godfrey is spending his day managing the forces of the Azur Lane naval coalition. Last month, the famous pirate ship that used to belong to the pirate Bartholomew Roberts was found. After the salvaging process, someone accidentally left a Wisdom Cube among the relics, and Royal Fortune was reborn. She was brought back to Oahu for inspection where she was tasked with exploring the ocean depths due to her lack of need for breathing and ability to control and summon sea creatures.

Anyway, back to the present:

Royal Fortune: Captain, I have a report. There was a portal 150 klicks away from the city.

Arthur: Is there any Siren warship around it?

Observer Alpha: What a coincidence. I was about to tell Dad the same thing. Empress sent me here to inform you

Royal: I did see a fleet of wooden ships emerging from it. They looks similar to Roman warships in history. I went back here immediately afterwards, so I don't have any idea if they were hostile or not.

As they were talking, a naval officer ran towards them.

Officer: Fleet Admiral, I received communications from our airbase at Kaneohe minutes ago. They informed me about a hostile fleet packed full of troops terrorizing our civilian boats, with another portal in the city center as well!

Arthur: WHAT? Send our forces to eliminate them! ASAP!

Officer: Roger that

Arthur: Fortune, can you whisk away the shark around the area?

Royal: It's no problem.

Over the sea, hundreds of wooden ships are boarding and capturing civilians as they advance. Reaching the beaches, they deployed not just humans, but beasts as well. The invading army advanced towards the city. Wyverns could also be seen emerging from the portal, flying towards the city of Honolulu. At their forefront was the largest and most decorated vessel, stand atop is deck is a general wearing exquisite armor. (well, for their kind) He opened the scroll and loudly announce:

"Listen up well, all you savages! In the name of Emperor Molt Sol Augustus, we, the Empire, declared the conquest of all these lands!"

It was the final sentence of his life. An F-8 Crusader shot him to bits, with two squadrons following behind. The giant has responded. Behind the invading fleet, the fabled shipgrirls of Azur Lane emerged from the horizon.

Meanwhile, inside the city, Imperial soldiers were pillaging anything in their way while murdering the hapless citizens of Honolulu. Orcs and goblins followed behind their footsteps, smashing walls and houses apart with their clubs and axe. In spite of the chaos, a girl with petite stature, white hair and golden eyes stood undaunted in front of their advance. The Imperials stare at her with confusion. One of them yelled out:

"Are you here to beg to be taken as a slave, filthy girl?"

"Don't you have any better words to use, weakling?"

"Huh? You dare talk back to me, a proud soldier of the Empire?I'll kill you!"

His head was decapitated before he even realized. The girl, with a head firmly on her hand, gave a manic grin.

Purifier: Does anyone want to have fun?

About ten blocks next to Purifier's killing ground were a platoon Eagle Union Marines, both infantry and armored, mowing down columns of enemy infantry. Many more Marines were coming from every single road, swiftly pushing back the invaders. At end of the "battle", forty thousand enemy troops were killed, two hundred ships were destroyed and one thousand POWs were captured.

In a single day, the medieval army were beaten, the survivors were captured as prisoners of war. Both portals were closed not long afterwards, but the other world's coordinates had been found and the Sirens opened another portal lead to the exact place. World leaders were told of the invasion an hour after their immediate retreat, and a joint force comprised of two infantry division, supported by Azur Lane, were deployed to what lies beyond the portal. Upon arrival, they constructed a large military compound at the shores of Blue Sea, near Alnus Hill. After a few months, the compound was operational.

At the second day, an aerial reconnaissance unit, commanded by August von Parseval, took off to take photos for mapping, during the process they passed through Alnus Hill and spotted a military base.

August von Parseval: *on radio* Commander, we are not the only otherworlders here. My planes spotted a military base on a hill

Arthur: Very well. You shall return to base and send us the photos and your flight course.

Minutes later, Arthur gathered all of the present girls and officers to discuss about their next course of actions. The decision was to avoid the airspace around the JSDF base, and a ground recon team will be sent.

Arthur's recon team:

Enterprise

Bismarck

Duke of York

Amagi

Takao

Sovetskaya Belorussiya

Observer Alpha

Tester Beta

Meanwhile, on Alnus Hill, Lieutenant Youji Itami was preparing to meet his recon team for the first time, but stopped on his way when looking up at the sky. He jabbed at one of his fellows, Akira Yanagida to get his attention:

Itami: Hey Yanagida. Those planes....they aren't ours.

Yanagida: Could it be that there is more than one Gate?

To have a better sight of the airplanes, Itami used his binoculars then let Yanagida use it.

Itami: Those symbols on them don't belong to any of the air forces back home, Yanagida.

Yanagida: I'll go inform the general.

When Yanagida told of what they have discovered, General Hazama immediately ordered all recon forces to act with extra caution, lest they may bring another, possibly superior, enemy at their gates. Itami's recon team departed at the same day

Third Recon Team:

A few days later:

Itami: The forest is on fire.

Itami's companion, Takeo Kurata, spoke up:

Kurata: This fire seems a tad bit too big for the current weather.

"Perhaps a large creature lit it on fire?", the team's Second-in-Command, named Soichirou Kuwahara, said:

From the smoke, emerged a silhouette of a large red dragon.

Kuwahara: Is that a one-headed King Ghidorah?

Shino Kuribayashi: Second Lieutenant Itami, what are your orders?

Itami: Randomly burning things doesn't seem to be a trait of dragons to me. Do you think so?

Kuribayashi: Why don't you take a look by yourself?

Itami: I'll be scared if I go alone. Will you come along?

Kuribayashi: Declined

Itami: .....I think we shall wait for the dragon to fly away.

Unbeknownst to Itami, another recon tea are also present.

Arthur: My my, what a large bonfire.

Amagi: I afraid it's too big to be called such, Commander.

Enterprise: And I see a dragon.

Bismarck: Shall we engage it, Commander?

Sovetskaya Belorussiya: I want to test our weapons on it.

Arthur: No, we stay on mission.

Purifier: Awww, no fair. I want to fight it. It looks strong!

Arthur: No Purity, no fighting.

Takao: She behaves just like Roon.

Purifier: I take offense to that! Don't compare me with a yandere!

Observer Alpha: I would like to have a sample of this specimen.

Purifier: At times, I wonder if you are a sampling fetishist or not, Alice.

Observer Alpha: Say that again and I will see your head thrown over to the dragon.

*Bonk* x 2

Arthur: No fighting amongst each other, kids.

Apha & Purifier: Owww.....Sorry, Dad.

Duke of York: The scent of death emanates from the forest. Dost thou wish to investigate?

Arthur: After the dragon fly away, we will proceed

The dragon left the scene afterwards. At the moment it left, Arthur created artificial rain to douse the raging wildfire. What once was a lush forest were now a charred wasteland. Only the toughest and/or luckiest could hope to survive the inferno. Arthur's team moved forward to investigate if anything survive. Not even one minute after, they encountered the Third Recon Team.

Among Third Recon Team:

Kurata: Hey Lieutenant, remember when I whined about not seeing any sexy demihuman girls yesterday? I think I found the jackpot.

Itami: There's even a vampire and a tentacle loli among them.

Tomita: Is it just me, or are there really naval cannons attached to their bodies?

Kurokawa: ....It's not only you.

Purifier: Are you going to introduce yourselves or just stand there?

Itami: Oh, I'm sorry. I am Second Lieutenant Youji Itami, commander of the Third Recon Army of the Japanese Self Defense Force, JSDF for short

Arthur: And I am Fleet Admiral Arthur Godfrey, Commander-in-Chief of Azur Lane Naval Coalition. I believe you guys have many questions, and fortunately my team has time.

*One introduction later*

Itami: Your world has quite a history, Sir Arthur.

Arthur: Yeah, I know right? We just done with our version of WW2, and boom, we have extradimensional beings on our waters

Itami: And your shipgirls.

Kurata: I always thought shipgirls only exist in games. Never thought I would see them in flesh one day.

Itami: You going to woo them, or no?

Kurata: I'm an otaku, not a jerk, commander. I know full well to respect veterans.

Arthur: Wow, never thought to meet otakus in this land. Fact: I'm a weeb.

Kurata felt very surprised. Itami, on the other hand, didn't pay much thought to it

Kurata: You don't seem surprised, lieutenant. Don't tell me you've met an otaku bigwig in the past.

Itami: Yeah...the Minister of Defence is one, y'know.

Kurata: Wait what?

Arthur/Itami: Everyone is a potential weeb, kid.

Purifier: Hey guys. I found someone under the well. She's an elf.

???: A bloody elf under the Well?

Everyone turns to the individual that wears a gas mask while he's wearing a uniform that is unknown to them, and he's holding a shotgun. But on his left sleeve he has an insignia of the Union Jack, so we assume that he's british

Duke of York: Why does your group have a Brit, sir Itami?

Itami: High command assigned him to our team. He swears quite a lot.

He does a quick salute with two fingers on them, Arthur saluted him back.

Thatcher: S.A.S Unit, Codename: Thatcher. Can't use my bloody real name 'ere, mate.

Arthur: Not a big problem to me. Alice, how's the elf girl doing?

Observer Alpha: Her vitals have stabilized.

Arthur: Now move to next problem: That big fat reptile.

Thatcher: I was fuckin told about this, twats couldn't give me a bloody briefing.

Arthur: Can't blame the Japs, they are just as blind as you are.

Thatcher: And what the bloody 'ell ya think of that, mate?

Arthur: I have seen enough shit to not react at the sight of a dragon. For example: a floating fortress with laser cannons. (Only Thatcher can hear)

Thatcher: Does it run on electricity?

Arthur: Yes. Anyway, I believe we should go and warn whoever we will encounter about that hungry lizard.

Meanwhile:

Alpha: *whisper* Hey Purity, should we tell Dad that Thatcher guy's voice sounds familiar to one of the many commanders of Azur Lane we've encountered?

Purifier: *whisper* I think he already knew.

Back to everyone else:

Thatcher: I should remove this bloody mask, before I waste it's fuckin air supply.

Thatcher turns off the air supply on his mask before he removes his mask. He puts the gas mask in one of his bags, then he takes his glasses to wear it

Thatcher: *Exhale* This is bloody better.

Duke of York: Dost thou afraid of potential toxic gases or something?

Thatcher: S.A.S have a habit of wearing bloody gas masks for toxic warfare, and bloody fear factor. Take out operation nimrod for example.

Duke of York: I forgot thy world is 60 years ahead of mine.

Thatcher: Want me to give ya my fookin real name for thou?

Duke of York: Go on.

Thatcher: *sighs* Arthur Pendragon.

Arthur: (A distant relative of another King Arthur. What a diverse group here)

Duke of York: Dost thou have a connection to the legendary King Arthur or something?

Pendragon: Yup, this isn't my bloody first on dimension travel.

Arthur: So you are the same as I am. I lost count of how many time I traveled between dimensions long ago. (Small enough to not let Itami's group hear)

Pendragon: This was my fookin' third. (Considering I have Excalibur behind me)

Arthur: I suggest we hop on our vehicles and continue our chit chat on the way. We have spare seats.

Arthur: Thanks, mate

On their way to.....whereever the map leads:

Arthur: So, is your ancestor male or female? King Arthur, I mean

Pendragon: King Artoria, Gender: Female.

Arthur: Lemma guess. Yours is the big booba blonde version?

Pendragon: Ya bloody got it. Unlike her, I don't have a bloody large appetite.

Arthur: And you certainly don't have a certain "D*** Wizard" being your advisor.

Pendragon: Fook that twat, he bloody scarred me.

Arthur: And for the sake of our brains, I won't talk about the red chick's explosively rebellious phase and THAT family problem.

Pendragon: Oh I met her, she's a nice birdie.

Arthur: Did she succeed in her quest to gain your ancestor's positive attention? Far as I know, the number of Mordreds who reconciled with their "fathers" can be counted on my two hands.

He shakes his head

Pendragon: She got mine.

Arthur: Good for her. And fuck Morgan le Fay.

Pendragon: She's my fookin grandaunt, and the bloody reason why I'm fookin isolated!

Arthur: I can't help but be amused at the fact that calling for your grandaunt technically equals to necromancy.

Pendragon: She bloody raped me before.

Amagi: ...You are ebing too loud.

Arthur: Aw shit. So that means everyone in this APC heard the "raped" part?. (Good thing radio's inactive)

Pendragon: Yup, but good fookin riddance for her. That fookin happened when I was young.

Arthur: Did you get to have payback? Not necessary to be in bed.

Pendragon: I'm not a fookin sod, mate.

Arthur: Y'know, I have a grimoire that records Noble Phantasms. Whatever fucking thing I think could become reality. But I can control it.

Arthur: Bloody 'ell, bruv.

Itami: Village's up ahead.

Arthur: Time to hop off and interact with locals. I believe you can speak their language, Pendragon?

Pendragon: What's their bloody language?

Arthur: *Slaps (not literally) the ability to speak Special Region languages inside Pendragon's head* There. That shortens things. I learned this shit the normal way though.

Pendragon: Crikey.

Itami: The chief said they must evacuate before the dragon reaches here.

Pendragon: *He talks to nothing behind him* Ya ready for dragon slaying?

Arthur: Let our comrades have their moment to shine, mate. It would be boring if things ends too quickly.

Pendragon: Well that's bloody sad innit?

Arthur: Aye.

Pendragon: So you're this Arthur Godfrey or something, mate?

Arthur: That's the name I randomly came up with when watching "If the Emperor Has a Text-to-Speech Device, BEHEMOTH Trilogy." I am a servant of Yog-Sothoth, actually.

Pendragon: ...What the fook is a "text-to-speech"?

Arthur: It's irrelevant.

Pendragon: What the fook are these bloody tossers makin' these days? First this bloody bluetooth, now this bloody text-to-speech?

Arthur: Science rise, magic decline. Boom, technology, voila.

Pendragon: *Pulls out an EMP Grenade*

Arthur: We won't need it against the Empire, so better not tinker with it.

Pendragon: *Puts it back in the bag*

From 50 meters ahead, a wagon collapsed due to overloading. The JSDF men rushed to haul the cargo away from the road and Bismarck lifted the wreckage away, a blue-haired teenage girl approached them in curiosity. Suddenly a horse went crazy, almost trampling the girl, but Kuwokara shot it dead just in time

Arthur: That mage over there looks promising. I could sense great potential.

Pendragon: Bloody 'ell.

Arthur: Have fun.

Pendragon: Fookin 'ell. Do I bloody have to?

Arthur: Actually, no.

Pendragon gets out of the APC to head for that blue-haired teenage girl. He goes to her, then he starts asking her questions

At another place, Kuribayashi is asking for the shipgirls for a sparring match and Takao accepts the offer. To Takao's amazement, Kuribayashi was surprisingly fast and skilled, even for a soldier. She estimated that if Shino were a shipgirl, she could give even Hakuryu a hard time

Pendragon: Ya lost?

Lelei La Lalena: I'm just curious about you guys. You don't seem to be soldiers of the Empire.

Pendragon: Not me mate, I'm from another division.

Lelei: Are you mercenaries from other kingdoms?

Arthur: No. You will know more about us in the future. How's that family with the broken cargo, Itami?

Itami: They will walk on foot.

Pendragon: I can help on the bloody cargo

Arthur: You gonna whip up something from your disposal?

Pendragon: Fuck no

Pendragon stacks three of the cargo, before he ties it into a backpack using a nearby rope

Pendragon: I can do this. And as for you, blue-haired birdie, what's your name?

Lelei: I'm Lelei La Lalena. Nice to meet you. May I know your name as well, good sir?

Pendragon: Arthur Pendragon.

Arthur: And I'm Arthur Godfrey. Nice to meet you to, miss Lelei

Pendragon: Godfrey, remind me where we bloody heading?

Arthur: Probably Alnus Hill. The JSDF's base is closer to here compared to my military compound.

Pendragon: Alright

He starts carrying the 3 cargo strapped as a backpack

Pendragon: Lead the way, twats.

Itami: Will do.

The journey to Alnus Hill was, frankly speaking, perilous. The road was muddy, causing several wagons to be bogged down and require assistance. The mud slows everything to walking pace, sapping away stamina from the villagers. Pendragon turned into a Scottish on the way while he continued walking with five cargo, two on his hands while the three are at his back, and poor Arthur had to bear the brunt of expletives. At some point in afternoon, Arthur pulled Pendragon into his APC while leaving the cargo inside Alice's jeep.

At night, somewhere near the route to Alnus Hill, there were a band of former Imperial soldiers-turned-bandits planning to raid the "Coda Convoy (it's how Godfrey said)". Due to the crushing defeats at Alnus Hill, most of the surviving soldiers gone rogue, pillaging rural villages on their way. But tonight, the hunter becomes the hunted, for an apostle of this world's pantheon of gods have set sights on them. None lived to tell what's happened, for Rory Mercury is the apostle of the God of War and Death. Next morning, the convoy met Rory.

Itami: A goth loli?

Pendragon: What the fuck is a goth loli?

Arthur: You don't need to know, mate. But you do need to know that she's a demigod.

Pendragon: What's next? World ending monsters?

Arthur: Aren't we....technically fit that category?

Pendragon: I don't do world end, bruv. I cannot use bloody magic.

Rory: Where are you guys from, and where are you heading to, travellers?

Pendragon: Alnus Hill

Arthur: We traveled from Coda Village. Apparently the Flame Dragons has risen from hibernation. We helped them flee to safety.

Rory: And what are those strange wagons?

Pendragon: They're made out of Armor, bruv.

Rory: I see. *look at the shipgirls* (Those girls, they are soulless. But they look strong)

(Wisdom Cubes, by definition, aren't souls).

Rory: Can I have a ride on it?

Arthur: Not mine. You can ride on his instead. *points to Itami* (let's see how that otaku will react.).

Alpha: We have a problem. The dragon's here.

Arthur: Recon teams. Haul ass! Let's go, let's go, let's go!

Pendragon: *Looks around for something to drink*

Arthur: *Hands Pendragon a container of brewed tea*

Pendragon: Thanks *He drinks some of it* Ahh, it reminds me of london.

Arthur: *eating popcorn while watching his girls & Third Recon Team fighting the dragon*

Pendragon: How did it go?

Arthur: Stalemate

Tomita: .50 cal having no effect on target!

Itami: Keep firing. We can't let it kill more villagers!

Bismarck: The dragon's too maneuverable. We can't accurately hit the dragon.

Alpha: It's hide's resistance to lasers is high as well.

Inside Itami's Humvee, the elf girl suddenly wakes up and keeps pointing to her eye.

"Ono!"

Itami: The eyes. Aim for the eyes!

The flame dragon, realizing where it's adversaries is aiming at, stops flying and uses its wings to cover itself from incoming fire. Seizing the chance, the shipgirls intensifies their bombardment to pin down the dragon, while Third Recon Team's heavy weapon specialist fired his Panzerfaust-3, the rocket propels itself toward's the dragon's head. As if able to sense the danger that rocket poses, the dragon steps aside, almost successfully evading it. It would have, if not for Rory's axe throw knocks it off its footing. It's left foreleg now blown off, the dragon ran away in defeat. The hand was retrieved by Observer Alpha.

Arthur: That went quite well.

Pendragon: Yup. Just to let ya know, I cannot do magic that can end worlds.

Arthur: Thanks for reminding me. By the way, I bet the rumor of our team fending off the dragon will be spread far and wide.

Arthur's group followed Itami's to Alnus Hill, reaching the military base at midnight. From there, they introduced themselves to Lieutenant-General Hazama and told his command chain about their world. From now on, they are (unofficially) allies.

At dawn, Arthur saw Pendragon sitting on the walls of Alnus Hill Military Base. He sat next to the younger man.

Arthur: Are you watching the rising sun, mate?

Pendragon: Yup

Arthur: A nice sunrise, with no air pollution tainting it. I start to like this place. *Hands Pendragon the permission to enter his naval compound*

Pendragon: What's this?

Arthur: Permission to enter my military compound. And here's the map *hands it*

Pendragon: Thanks.

Arthur: I'm going to take a look at the construction for refugee accommodation.
