Halo-22-557 timeline.

It's pitch black, that's what we see when we're in outer space. But the darkness turned bright blue after several Covenant Battlecruisers fired dozens of their Plasma Torpedoes at something.

Fleetmaster : Whatever happens, we can't let them pass through this sector!

Crew: Understood!

The figure they shot at with Plasma Torpedoes was a kind of giant blue Dragon, all over its body embedded laser cannons that could split the planet, the roar of this creature was capable of slicing through space and time itself, this thing was 45 kilometers long and 15 kilometers wide, and it only one of many kinds. Meanwhile around the Being, there were hundreds if not thousands of small ships with tentacles behind them as if the tentacles were propellers. Well, by small you mean 3 kilometers long and 450 meters wide.

Sangheili Officer #1 : Fleetmaster! they destroyed the UNSC Firestorm and some of her escorts! Without the Spartan V they're carrying, we can't get board their ship.

Fleetmaster : bastard, what about the Sangheili colony in this system?

Officer Sangheili #2 : Evacuation operation is running stably with the help of the Sirens, the girls will finish evacuating in 6 hours.

The fleet's Fleetmaster scowled.

Fleetmaster : We don't have that much time... Did we get any news of reinforcements?

Officer Sangheili #1 shook his head.

Sangheili Officer #1 : Sorry sir, UNSC has not given any news at all, especially the Arbiter whom we cannot contact.

Fleetmaster : (clenching fist) Damn it!

Azur Lane World 104-789.

Nagato was seen giving Laffey and Javelin a lap pillow. Nagato with a big smile stroked the heads of the two shipgirls who were exhausted from playing on the beach. And beside her was Enterprise reading the latest issue of New York magazine.

Nagato : hey Enterprise.... this is quite... suspicious isn't it?

Enterprise : right, Siren can't be this silent, I'm not even getting any signal. Do you think they decided to go away for good?

Nagato : Hopefully, if that's really the case, I can finally focus on taking care of the Sakura Empire and retire.

Enterprise : you are really serious about retiring, huh?

Nagato nodded slowly and said.

Nagato : Yes, I'm serious. I've lived too long, and it's time to let the young ones carry on. (strokes Laffey's cheek affectionately.)

Enterprise : You sound like you just want to die. (joking)

Nagato chuckled.

Nagato : Yeah, I guess I'm thinking too much weird, huh?

Enterprise smiled and nodded. Before finally the two their Radar spotted something and looked straight into the ocean. There was a Shipgirl with white hair and pale skin approaching- It's a Siren Shipgirl!

Enterprise immediately summoned her Bow, while Nagato put the two shipgirls on her lap onto the towel, and she immediately summoned another AF-14 assault rifle.

Enterprise : stop there, Siren!

The siren stops on Enterprise's request/command.

Lurker #SS-107-89 : W-Wait a minute! I came with good intentions!

Enterprise: (grunts) Yeah, right. We've tried that a few years ago and finally now every country has a vacancy in the chair of leadership.

Lurker #SS-107-89 : Y-You know we're just carrying out orders right? Ah! but that's not what I want to say. (Inhale) I surrender myself to you.

Nagato & Enterprise : Huh?

Enterprise : what do you mean, surrender?

Lurker #SS-107-89 : I don't want to fight anymore, I'm tired. I can give you anything, technology, the place where we hide our gold, hell, I'll even give you my Black Mental Cube!

Nagato approached the Siren with her gun aimed at the Siren's head, while Enterprise remained behind and she called for backup.

Nagato : why did you give up? What really happened?

Lurker #SS-107-89 : We.... We were attacked by... by "Them"! A vile creature that treats stars like snacks, eats galaxies like dinner and tore apart space and time like.... like space and time were made of paper!

Nagato widened her eyes in disbelief.

Lurker #SS-107-89 : Thousands of my sisters have died facing this vile creature, I, I.... (fainted)

Nagato who was near the Siren immediately caught her before she fell into the sand.

Nagato: Prise!

Enterprise : Got it!

Enterprise immediately picked up the Siren and ran to Medbay. Nagato let out a trembling breath.

Nagato : what kind of bullshit am I living again?

In the middle of nowhere.

In the Cartographer's room.

Several Siren Shipgirls were running around like headless chickens, with documents and tablets in their hands. While Observer Alpha looks at the Halo-22-557 timeline which is starting to be "Eat" by the "Devourers".

Alpha : no... no... how did this happen?! Oceana!

Oceana #HC-420-69 : Madam?

Alpha: where are the Ashes?! Did they make it out of the timeline?!

Oceana #HC-420-69 : (swallows harshly.) Madam.... All the Ashes managed to escape except for one, USS Helena did not come out and hold all the Creatures along with the remnants of the UNSC and Covenant fleets... We got last transmission with her. Playing transmission USS Helana-001-01.

USS Helena-001-01 : Listen to me, you damn cock! We sentient beings of the alliance between Timelines, we spit at your so call Greatness. We will not kneel before you! Alpha, and the other! We leave the rest to all of you. Masterchief, will you do the favor?

Master Chief (John-117): With honor, Maam.

*click*

The transmission was cut off with a giant booming sound and then silence...

Alpha hit the table in front of her, she looked at Helena's META Hologram Face with a look full of regret.

Alpha : I'm sorry.... I'm really sorry, Lena... Godspeed, you magnificent bastard.

Oceana #HC-420-69 : Madam? I... have news for you.

Alpha sighed and asked.

Alpha : good news, or bad?

Oceana gulped.

Oceana #HC-420-69 : .... Some of our assets in the world 104-789 are starting to rebel against the Observer.

Alpha raised her eyebrows.

Alpha : what did the Me in that timeline say about this?

Oceana #HC-420-69 : she said... She wants them to be free and determine their own destiny. And you in that timeline want them to enjoy their life, according to their age.

Alpha sighed softly.

Alpha: if the situation was normal, maybe I would cheer up and monitor the timeline further, but we have a much bigger problem. What is the status of our star shipbuilding?

Oceana #HC-420-69 : Ah that, Madam Tester Beta-55 says she can have 250 Infinity-class super carriers ready in two weeks.

Alpha: Two weeks? tell her she only has one week.

Oceana #HC-420-69 : Got it, oh and uhh the rebuilding of Purifier Unit. In total there are 150 new Purifier units.

Alpha grimaced when she heard the number.

Alpha : That's... very little, no 4 percent of our losses at the start of the war. Have you heard anything from the Arbiter?

Oceana #HC-420-69 : (Shakes) They're still looking for candidates across multiple timelines to help fight the Scourges.

Alpha raised her eyebrows.

Alpha: Scourge? what's that?

Oceana #HC-420-69 : Ah that, everyone started calling them Scourge or Leviathan to make it easier.

Alpha scowled.

Alpha : oh I have a nice name for them, Smelly Cock.

The Cartographer's door opened and there was a Dreamwaver escorted by several Spartan-IVs and dozens of ODSTs entering with bitter faces.

Alpha: Hmm? Dreamwaver? what is it?

Dreamwaver : Haah~ Alpha, I would like to report that Halo-22-557 was completely destroyed due to the simultaneous explosion of the entire Halo array and several giant solar cores. I... managed to save a few people from that timeline, unfortunately I didn't manage to save the IIs.

Alpha : Its okay, at least we can save some of them. Dreamwaver, where will the Leviathans go next?

Dreamwaver nodded to one of the ODST, and the ODST gave a Flashdisk to Alpha. Alpha accepted the Flashdisk and nodded gratefully.

Dreamwaver : then excuse me, they all need a break after... all the hell they've been through.

Dreamwaver walked out again followed by IV and ODST.

Alpha looked back at the Cartographer with a determined look.

Alpha : soon... soon...

Azur Lane World 104-789.

Alpha-789 let out a long sigh as she looked at the working Siren Base blankly. Alpha-789 grimaced at the blank stares of the Siren Shipgirls.

Alpha-789 : Damn.... I have to have a plan, should I ask the Azur Lane for help in this timeline? seems like a good plan.

Alpha-789 suddenly shivered in fear and looked up into the sky.

Alpha-789 : Oh no.... they're already in this timeline... I have to get to Pearl Harbor right away!

Alpha-789 directly entered the portal she created to Pearl Harbor.

Total war draws near to Azur Lane-104-789.

TBC

Sorry if this chapter is short and a little weird!

Oh wow.... I don't know how the story that was originally meant to beat Siren to a pulp, can become an intergalactic war between space and time. It seems that writing while you poop is a double-edged sword.

Well, I have no regrets. I've always liked Siren even though a lot of people think of them as uhh... Villains in Azur Lane Universe. Even though they can be called Anti-Heroes and only simply follow their creator's instructions, Doctor, what's the name of their creator, I forgot a little.

See you in the next chapter!

This literally the shit that Original Shipgirls fight back in Original Timeline :
