Pacific Ocean
Area B7R
1627 Hours

The smell of smoke and burning oil filled the air around the area, along with metal scraps from destroyed Siren ships. The sky's beautiful blue was replaced with bloody red color. Thunder was sounding, artillery pounding, as shells and laser beams whizzed in the air. Wrath of the Sirens cast on B7R, facing their forces alone were five lone figures making their last stand, either shooting any Sirens within range with their cannons or slicing them with their swords if they got close.

One of them was a (H/c)-haired male, badly wounded, his #1 and #3 turrets on fire, and was left with two barely functioning cannons as critical damages were visible all over his weapons. It was no other than (Y/n) or Montana, the lead ship of his class.

The second one was a female with long black hair and a curvy figure. She wore a seemingly odd black and uniform, showing a portion of her chests. On her head was a black hat, matching her outfit. Iowa, the lead ship of her class.

The third one had a blue hair and blue eyes. She wore a black suit merged with a rather short pencil skirt that emphasized her curves, black tights, and a large white coat with transparent blue that is now tattered, covered in blood and soot. On her arms were long white gloves with metal pieces attached on her wrists, and on her head was a metal piece with two long metals sticking out. New Jersey, the second ship of Iowa-class.

The fourth one was a green-eyed girl with a blonde hair. She wore a white outfit with a red ribbon on her chest, black short skirt, thigh-high socks, and white shoes. Missouri, the third ship of Iowa class.

The last one had a brown hair and green eyes. Her outfit was consisted of a black and white uniform with a red ribbon, black leggings, a pair of black gloves, and white high heels. Wisconsin, the last ship of Iowa-class.

The combatants were heavily panting due to exhaustion and injuries. Around them were the bodies of their deceased comrades, killed in unimaginable ways, making it hard to identify them.

"DIE!!" Wisconsin screamed, firing salvo after salvo of shells at the Siren ships. She dodged to the side, barely avoiding a combination of laser beams and plasma rounds. Wisconsin retaliated by firing her last two Tomahawk missiles at the alien ship.

Up above were two F-35B Lightning IIs, preparing to drop their payloads at the opposing fleet. As the two aircrafts got a lock on the Siren ships, they were suddenly getting bombarded with anti-aircraft fire, forcing them to dodge. The jets soon got hit, but they managed to drop their payloads before they exploded in a fireball shortly after.

Iowa grunted in pain when she got hit by an enemy shell. She aimed her cannon and fired, the 16-inch shells easily penetrating through its armor.

"Sis!" Missouri rushed to her side. "Are you okay?!"

Iowa coughed a bit. "Still breathing. Don't know how much longer, though..."

On the other side of the battlefield, (Y/n) was weaving through the barrage of both AP and HE shells while firing his own barrage. The battleship lunged at a humanoid Siren and held her by the throat, snapping her neck as he threw the Siren's dead body back to the enemy fleet.

Just then, a stong energy blast sent him flying, making him slam against a hull of a destroyed Siren destroyer. He coughed out blood and stood up, ignoring the pain the coursed throughout his body. "Piece of shit..."

"Oh, my. What a pitiful sight." A Siren with octopus-like tentacles hovered above him, her laser cannons aiming directly at him, ready to fire another shot.

"Observer Alpha." He growled.

"Fufufu~ We've meet again. This time, I'll make sure to give your head to the Empress!" The Siren smiled maniacally.

(Y/n) got into a battle stance. "Come at me."

"THEN DIE, YOU PEST!!" Observer Alpha fired her cannons at the battleship.

The beams hit area (Y/n) was standing at, covering the place with a thick cloud of smoke. As the explosion cleared, there were no traces of him, promting Observer Alpha's smirk to disappear.

"Where is-" Her speech was interrupted when she was kicked in the face by (Y/n), sending her flying to another humanoid Siren.

Observer Alpha shakily stood up, looking around for him, only to get roughly punched in the abdomen, throwing her high up in the air. (Y/n) appeared in front of her once again with great speed, his turrets aiming at her, point-blank range.

"Arrivederci." Those were the final words she heard before she got blasted into oblivion.

The male battleship landed in the water, creating a huge splash. A squadron of Siren jets suddenly flew past him, carrying high-explosive bombs. He examined their movements, until the realization hit him. Those jets were closing in to Iowa's position. His eyes widened in dread.

"Shit!" He quickly send his last two F-35's, dedicated for air-to-air engagements, hoping that they reach in time. Much to his relief, his own aircraft downed the enemy jets before they could even come close.

However, a huge plume of smoke rose from the said group's position. He cursed under his breath and sailed back to Iowa and the others.

The Iowa-class sisters weaved through the hail of lasers and plasma rounds from another high-class Siren, Tester Beta.

"Damn!" Wisconsin cursed, using her sword to deflect a beam.

"This is getting nowhere!" New Jersey added and rolled to the side, avoiding a streak of plasma rounds.

"Give up. You're outnumbered." Tester Beta said.

"NUTS!" Iowa's words echoed clear.

"Then die." Tester Beta's cannons began charging, but was interrupted by a salvo of shells impacting directly at her.

The girls turned their gaze at the source. "(Y/N)!!"

Tester Beta growled. "You... You'll pay for this!"

The Siren fired everything she could throw at him. While (Y/n) managed to avoid most of the incoming projectiles, some laser beams landed on their mark, piercing through his body and impacting on his turrets, resulting on the complete destruction of his rigging.

Despite that, he continued charging and summoned his sword. Tester Beta flew back in an attempt to get away, but the male had already closed the distance between them.

"BEGONE!!" (Y/n) swung his sword, inflicting a large gaping wound on her chest.

Tester Beta went limp, landing a few meters away from the group. Yellow blood seeped rapidly from her wound, mixing with the sea water.

"(Y/n)!" The Iowa-class sisters ran to him and gave him a hug, almost knocking him down.

"I'm glad you're okay..." Missouri cooed.

(Y/n) gave a dry chuckle, forcing himself not to wince in pain. "Sorry I'm late."

Just then, thousands of portals appeared roughly a few kilometers away from them. The shipgirls' face went pale, looking at the portals in horror and dread. (Y/n) clenched his fist in anger.

"N-No..." New Jersey mumbled.

"Big sis, what do we do...?" Missouri asked in a shaky voice.

"I... I don't know...." Iowa responded.

The male kansen looked down, as if thinking of any other ways. 'Looks like there's no other choice. I have to use that...'

"Damn it..." Wisconsin grumbled, equally shaken as her sisters.

"I'm going." (Y/n) said to them.

"WHAT?!" They shouted in shock.

"I'm gonna overload my reactor." He added. "That will give you some time to escape, at least."

"You're joking, right?" Wisconsin said, only to get a headshake as a response from him.

"N-No... please... Don't do this... Don't leave us..." Iowa begged.

(Y/n) gave a sad smile and kissed her forehead. "I'm sorry, Iowa. I don't have a choice."

"Don't, please..." New Jersey hugged him, tears streaming down her cheeks. Missouri joined in and hugged the male kansen, their audible sobbing echoing in his mind.

"We don't want you to die..." Missouri whimpered.

(Y/n) patted her head. "As long as you wouldn't forget me, I will not die."

Wisconsin grabbed him by the collar. "ARE YOU STUPID?! DO YOU THINK WE WOULD LET YOU- GAH!!!" She winced in pain when (Y/n) took a syringe and stabbed it to her neck, knocking her unconscious.

(Y/n) placed her down gently. "I'm sorry." He whispered in her ear, giving her one last kiss before he turned around, sailing away from them at maximum speed, ignoring their cries.

They wanted to follow after him, but their wounds prevented them from doing so. Iowa, New Jersey, and Missouri could only watch in horror and sadness as (Y/n) charged onto the massive Siren fleet that was heading straight to them. Their riggings were badly damaged, so fighting back is useless.

'If this could bring back freedom and peace, then...' (Y/n) throught and smiled, his chest glowing bright blue. The light became brighter and brighter until...

BOOM!

A massive explosion that created a mushroom cloud engulfed the whole area, vaporizing the Sirens in the process.

"NOOOOOOOOOO!!!" Iowa shouted in horror and attempted to stand up, only to be grabbed by New Jersey. "LET ME GO, DAMN IT!!"

"HE'S GONE, SIS! (Y/N)'S GONE!!" New Jersey shouted.

"NO! HE'S NOT DEAD!" Iowa protested.

"WHAT THE FUCK IS GOI-" Wisconsin was shaken awake by the explosion, stopping mid sentence when her gaze landed on the mushroom cloud. "No... No... No...",

"I'm sorry, Wisconsin..." Missouri cried. "He's gone..."

"Was that it?" A voice came from behind, promting them to turn around.

"Empress..." Iowa growled.

'Empress' simply replied with a sadistic smirk. "Good, you still remembered me."

"You bitch!" New Jersey lashed out, firing her last three shells, only to get blocked by the forcefields that was protecting the Siren.

"I was planning on killing you, but that would ruin the fun~" Empress grinned.

Empress snapped her fingers and created a portal under them, sucking the shipgirls inside, their screams and figures fading into the darkness.
