The Abyssals.

Vessels risen from the darkness, the Abyssals wreaked havoc on humanity. Seaside towns were destroyed, trade routes cut off. Many navies have attempted to combat the Abyssals using their different warships, but none have succeeded. The Abyssals seem to be an unknown threat with no way to halt their reign of terror.

The war against the Abyssals had gone on for two years. Japan was running out of food, the citizens starving. The Prime Minister decided to hire a group of young Japanese scientists to find a way to counter the Abyssals so Japan could trade with the United States. The scientists split into separate laboratories near the ocean to observe and record the movements and strategies of the Abyssals. Of the hired scientists, one had an idea on how to stop the Abyssals. What if the navies of the world could summon their own versions of these Abyssals to combat them? And so, he went to work on constructing a grand summoning chamber. After around a week of work with almost no sleep, he stepped to the back wall to examine the fruits of his labor. Wires, everywhere, with lights flickering on and off. Spotlights shone on a large platform in the middle of the room which was dipping into the ocean. Along the walls hung a great many banners of the Imperial Japanese Navy. All that was needed was a calling. The scientist strode to a computer on a nearby desk and began playing the Japanese Navy March...

Sirens began to blare, a bright light shining throughout the chamber. The scientist had to shield his eyes to avoid getting blinded as the chamber crackled with energy. As he slowly opened his eyes, the light had faded away to show a feminine figure. A bit shorter than the scientist, she wore a short-sleeved serafuku and had a short ponytail at the back of her dark brown hair. She seemed to be utterly astounded at where she had showed up. The scientist developed a small grin, one of the few he'd ever had since becoming a scientist.

"If I may ask... What's your name?"

The girl snapped to attention almost immediately and saluted. "I am Fubuki, sir!"

"I see... Welcome to your new life, Fubuki. Mankind's counterattack starts now."

In a small town in the state of New Jersey, some sixty thousand miles from Japan, lived a teenage kid named Sean. He was widely considered a prodigy by anybody who knew him, yet he didn't believe he deserved such a prestigious title. Being relatively short for his age at four foot ten inches tall, he had short bright red hair the color of a blazing flame, blue eyes as deep as the ocean, and wore glasses to match his eyes. The combination of red tee-shirt and blue shorts he had on was a clear indication that he wasn't really a professional type of person. Sean was in his room experimenting with an odd device. His room was a mess, everything placed around haphazardly, the walls cluttered with posters of anime characters. On a desk was a television showing the news.

"There is a large Abyssal force headed for New Jersey after assaulting Maryland. A survivor's account claimed that the Abyssals were searching for a "Chosen One", and that they could feel as if they were getting closer to their energy-"

Sean picked up the remote to the television and turned it off. "The news is always so depressing... It's just the same thing over and over. Abyssals this, Abyssals that." He mocked the news sarcastically before he connected some wires to the odd device. As the wires connected, the device sprang to life, lights blinking everywhere on it. The device seemed incomprehensible, but it was doing something. Sean nodded, his instinct claiming the machine seemed to be working as intended so far. He was going to go all out to win his school's science fair, to crush the dreams of all of his competition.

The roof of the house suddenly collapsed around Sean and the device, revealing half the town scorched in flames and emitting a yell of surprise from Sean. He hadn't known it would be there that soon, as his blinds were closed and the sounds were blocked by his concentration. Sean could do nothing but stare on in awe as the Abyssal force mentioned in the news dug into his town. A lone Abyssal, seemingly their commander, walked up to him, a gun in his face.

[Come with us, or perish, Chosen One.]

Sean's mind was in pure panic. He didn't have any idea of what to do. His machine was still working, so maybe he could use it, but it didn't seem to be doing anything. Sean slowly held up his hands before attempting to throw a punch, which was promptly caught. "It was worth a shot, I regret nothi-"

Suddenly, a bright light filled the Abyssal and Sean's visions. As Sean slowly reopened his eyes, expecting a gun to his chin, instead he found the Abyssal on the floor, being wrestled by a girl seemingly his size. She had light blue hair and red eyes, and wore a red and white striped hoodie with jeans. Struggling to pin the Abyssal's shoulders down, she yelled to Sean in a soft yet serious voice "Get out of here!"

"Y-yes!" Sean bowed deeply and ran out of the debris of his house before looking back. His device was destroyed from a secondary collapse of the ceiling. As he turned around, a rope descended in front of his face, a helicopter in the air above him. The co-pilot to the airplane tilted out and shouted into his megaphone "Hop on, we're getting you out of here!"

Sean looked back to the girl wrestling the Abyssal. The girl was now on the ground being held by the Abyssal. "Hold on!" He dashed to the remains of the machine and picked up a metal pipe he had used to house some wires. Carefully maneuvering to the wrestling match, Sean brought up the pipe and smashed it against the Abyssal's head, instantly shattering the pipe and directing the Abyssal's attention to him for a moment. The girl took advantage of the momentary distraction and threw the Abyssal off. Sean offered his hand to the girl, who took it, and ran at full speed to the rope, grabbing on. The co-pilot began raising the rope, dragging Sean and the girl to the helicopter as it flew away from the carnage of the Abyssal attack, bombarded by but barely dodging shells and anti-air bullets.

"Hey, you okay? You seem down."

Sean sat in one of the back seats of the helicopter, attempting futilely to come to terms what happened a couple hours earlier. Abyssals attacked his hometown, destroyed everything, and probably killed his parents, who had gone shopping and didn't hear the news. The girl from earlier seemed to take an unusual liking to him, attempting to comfort him like a big sister during the ride to who knows where. Sean lowered his head at her question. "I lost my hometown... My family... I don't know what I have anymore..." He began to cry, the girl quickly responding with a giant hug. "Thank you..." Sean wiped his tears with his arm. "Where are we going...?"

The co-pilot turned to the two and showed them an United States Navy ID. "You're going to the Kure Naval Shipgirl Base under the custody of Vice-Admiral Soren. We've been watching you for a while. The Abyssals are hunting for you. We need to keep you and the Abyssals separated at all costs. You are crucial to mankind's counterattack. Welcome to your new life, Sean."
