Author's Note: Hello, this is my very first story here on fanfic. I got the idea after watching seasons 1 and 2 of Gunslinger Girl and reading the manga again and wondering how the nations of Hetalia could fit in with those events. Human names will be used.

Disclaimer:I own neither Gunslinger Girl nor Hetalia. They belong to Yu Aida and Himaruya Hidekaz, respectively.

Switzerland checked his SIG P226 to make sure the magazine was loaded. The faint sound of construction could be heard outside.
"Just another day at the job," he muttered under his breath.

He looked to his side where his partner, or cyborg, as they were called, was standing. Her shoulder-length blonde hair matched his and many would mistake her for Vash's little brother if it weren't for the ribbon in her hair. She looked any ordinary child who wore jeans, a t-shirt, and a denim jacket except she had a SIG P228 hidden in her jacket. There was also the fact that she wasn't an ordinary child at all for she was way older than she looked.
"Bruder," Liechtenstein said. "Is it time to move?"

"Yeah, move out, Lili. You know the plan. And remember, be careful."
With a nod of her head, she moved out from the corner they were hiding behind and began walking towards their target destination down the hallway. Vash followed closely behind, flash bang at the ready. The sound of construction grew louder as they approached the door.

"Who is it?" a voice questioned when she knocked the door.
"Just a little girl, sir. I was wondering if you'd like to purchase some girl scout cookies." She motioned to her backpack.

The door opened slightly as a man looked through to observe his visitor. Unfortunately, he couldn't see the Swiss man hiding out of sight just next to the door frame.

"Just what the hell ar-" His voice was cut off as Lili grabbed him by the collar, pulled his head through, and slammed the door on his neck, breaking it. Surprised yells sounded from the inside and the clacking of weapons could be heard. Switzerland tossed his flash bang in through the small opening. As soon as it went off, Lili kicked the door open and took aim, Vash following right behind.

I count seven targets. We have to make this quick, he thought to himself as he quickly scanned the room.

Lili was the first to open fire as she emptied 4 rounds in quick succession. Vash quickly killed the three men on the left side of the room at the same time the four men on the right side dropped dead to the ground. The bedroom door across the room was kicked open as five more men poured into the living room, opening fire on the duo. The element of surprise was lost and Vash opened the nearby fridge door and took cover behind it as Lili dove into cover behind the large sofa.

"Lili, pull out your MP7! I'll cover you!" Vash blind fired around the fridge door and the insurgents quickly hid behind a turned-over table.

Lili dropped her backpack and pulled out her MP7. After Vash stopped firing, she popped out of cover and opened fire. Two men were pockmarked with holes by the deadly 4.6mm rounds and the remaining three retreated back into the bedroom, firing their AKs like no tomorrow.
"Ivan, this is Vash. I got three guys holding out in the bedroom of the target area. There is way too much fire and my fratello can't move up. I could use your help right now!" he yelled into his mic.

Grunts of pain were heard, each followed shortly by a nearly inaudible crack. Vash and Lili moved in as soon as the enemy stopped firing.
"Room cleared. Thanks for the assist, Ivan," Vash said into his mic.
"Da, it was no problem. Although you could ask nicely every now and then, hmm?" Ivan replied.

On a nearby rooftop overlooking the apartment, Ivan radioed back to HQ.
"Mission accomplished, Alfred. Send in the cleanup crew and you can tell our construction workers they can have the day off."
"Roger. Roddy and Liza are already on the way up. The Nordics will accompany them later,"

Ivan ended the transmission and said to his cyborg, "Good work with the shooting, Natalia. But next time, make sure to be quicker or else." Then he turned around and left.

"Yes, big brother," the Belarusian replied. She picked up her SVD and placed it back in her case before hurrying after the large Russian man.
