[Halo 25XX]
"Everyone retreat!" UNSC Akagi signal as she continues to return fire at the Sirens. She thought this mission wouldn't be hard, but it quickly went down south.
One of the recon ships discovered Sirens transporting something of dangerous high readings. The UNSC wanted that package to be stopped or destroyed before it can do any harm. Castle Platoon was the fleet closest enough to intercept the cargo. Unfortunately, the recon intel was unable to get the number of enemy ships nor class due from the high reading jamming. When they arrived, they were assaulted with many Upper-class Sirens that were the hidden escort. Castle Platoon is an enduring fleet of ship girls, containing multiple Paris-class heavy frigates, a few Marathon-class heavy cruisers, and lead by an Epoch-class heavy carrier. Like a castle, they were able to hold their ground, but the objective was getting away. Sooner or later they would lose their footing as they weren't prepared to face this many Upper-class Sirens without reinforcement. It was nearly impossible to breakthrough their blockage without getting destroyed. Akagi, codename Castle One, has to decide the next plan of action of her platoon. If they all pushed, they might be able to reach the target with everyone wiped out or leaving few nearly dead. Without backup coming anytime soon, holding them will result many frigates lost and cruiser heavy damage.
"I want all frigates start their slipspace and the Marathons will follow!" Akagi ordered.
"""Understood! """ The Paris sisters called out and prepared their escape.
"Castle One there's a high output coming from that Upper-class Destroyer Siren" One of the Marathons warned. Akagi spotted the Siren Destroyer loading a massive Missile.
'It has a missile with that much energy?!' Akagi guessed it was some type of nuke.
The Siren fired at the retreating and soon a gigantic dark explosive sphere, erupted where the Castle once stood or retreated from.
[Somewhere in the Arctic Region]
The special combat zone collapsed soon after Enterprise defeated Akagi. Both Azur Lane and Sakura Empire Fleet were left stranded on some icy sea with cracks of space & time visible on the air.
The Sakura Empire Fleet has regather their numbers all except their flagship, Akagi. The mass-production Siren, controlled by Akagi, all crease to function and floating silently.
"It won't budge. Did it overheat or something?" Ikazuchi asked.
"Could this be another ploy by the enemy?" Akatsuki thought.
"I wonder what happened?" Fubuki asked, not sure what going on anymore.
"The mass-produced Sirens have shut down..." Atago stated the obvious.
"Not just one, but all of them...?" Takao glanced at all the Sirens, seeing none of them working.
Another rift in the sky open, causing more instability to the ice bergs around. The Sakura Fleet has to soon leave the area before any ice fall or crash into them. What they didn't see, was a person falling from the sky towards a large mass of ice at dangerous speed.
*CRASH*! A loud sound echo through the ice and alerted some the Sakura shipgirls.
"Wh-what was that!?" Fubuki's ears stood high.
"Are we under attack?" Akatsuki's caution eyes searched
The eyes of the destroyers and heavy cruisers followed the trail of water ripples, falling ice, and smoke coming from the large ice berg, now heavily cracked.
"Is that someone?" Inazuma caught sight as the fog faded away.
The four destroyers went to check, along with Atago and Takao to make sure the destroyers' safety. Upon reaching the site, the person in question laid unconscious. A woman with red and black hair wearing an unknown reddish green military uniform.
"Look at those armaments." Ikazuchi and the others were curiously amazed at the large and many weaponry she holds.
The most eye attracting is the massive cannon of a very cool design followed by two cannons, also unknown design. It was a surprise to them of her holding so many other cannons.
"Extremely powerful..." Akatsuki
"Should we help her? I don't think... she's from Azur Lane or Siren." Fubuki suggested and Atago observed closely, deciding their next action.
"Sister...?" Takao wondered her answer.
"Let's take her back home, where it's nice and warm from this place. We can speak to her once she wakes." Atago said with a smile.
The rest of the girls nodded and the destroyers help left up the mysterious stranger.
"""Heavy""" Akatsuki, Ikazuchi, Inazuma, and Fubuki voiced out their thoughts as they barely able to lift her arms and legs. Atago and Takao switch with the two destroyers and are able to carry her back to the retreating fleet.
[Far hidden from the field]
"An unknown variable has appeared." Observer Alpha said.
"An unknown?" Tester wonder what Alpha has never observed before.
"I'll collect data from her later, now that the black mental cube gathered huge amount of data. All thanks to Enterprise to commit such efforts."
"Did you pick that thing up?" Tester said.
"Why, yes. She still has a role to play and with the black mental cube, project Orocho can commence." Alpha smiled as the distraction battle between two Sakura carriers vs Azur Lane.
Shoukaku and Zuikaku were able to enough buy time for the fleet to retreat and themselves to escape, but not without consequences. Ayanami was captured by the enemy and Shoukaku suffered heavy damage. Zuikaku carried her sister back to the fleet, who were halfway back home.
"Get Shoukaku bandages!" Souryuu quickly ordered.
"Your gonna be ok, Shoukaku-nee." Zuikaku gentle laid her down.
"Don't be hard on yourself, Zuikaku. With some rest, I'll be able to stand again." Soon the other girls with medical knowledge start applying the bandages.
Shoukaku's right arm suffered the most damaged with minor head injuries will rest for the entire trip before reporting to Nagato. Kaga began recovering her strength yet she's still mad at Souryuu and still weak to move much.
*rebooting*
"System reboot...successful."
"..." *goan* Akagi slowly began to regain consciousness with a major headache. The sound of warning beeps, requiring her attention, didn't help with the headache. Sooner or later the mysterious stranger will have to answer the call of the new reality.
Writer: Man another crossover, I really don't plan out my fics. Oh well, I hope you like this chapter and chapter 2 will come hopefully in a week, if FGO Saber Wars doesn't consume my time.
