HetaliaxReader: She's MY Little sister! (Part 1)

Dear (FirstName) (LastName),
It has come to our attention that you have an outstanding amount of supporters in our “Build-A-Country” computer game. In fact, you have created an uproar to which hundreds of thousands of people have donated money to building your country on a recently discovered island in the Pacific.  We request you attend the next World Meeting to integrate and acquaint you with the other countries.
Sincerely,
Hetalian United Nations


You folded the letter up after reading it for the billionth time, making sure it wasn’t some kind of joke. You tucked it into your pocket, and looked at the big wooden door that stood before you. The door was engraved with the letters: HUN. Hetalian United Nations? What the hell is that, exactly?  United Nations was mentioned God knows how many times in history class, but what is Hetalian? This whole ordeal seemed less legit every time you thought about it. You had never even seen this place before! In fact, If it wasn’t for the directions and address on the back of your letter, you would’ve never found this large, school-like building. Once again, you questioned if this was an actual thing. You half expected someone to jump out and say “You just got PUNK’D!”  You could feel your face heat up in embarrassment. “What if this is some kind of dumb prank? I’ll look like an idiot for believing it!”  You said under your breath.  Just then, you realized that if this was a prank, it was sure as hell well planned out. To make a fake letter from a fake organization in a fake building? Ain’t NOBODY got time fo’ dat! You decided you might as well give this a shot. What have you got to lose?
You placed your hand around the silver doorknob and turned it slightly. Click. You pushed the door open, emanating a loud creeeEEEEEEEeeeeeak from the hinges. What was in the room almost made you pee your pants. All hell had seemed to break loose sometime before you got there. A man with choppy blonde hair was trying to strangle a long-haired blonde man; a man with reddish-brown hair was hiding behind a buff-looking blonde guy who was trying to punch another guy in the throat; a shorter man with black hair seemed to be in a heated conversation about something to do with Hello Kitty with two other men with dark brown hair; a taller guy with dark blonde hair and glasses was running around yelling and apparently trying to beat a record of how many people he could piss off; a  bigger guy with almost white-blonde hair and a scarf was standing with three trembling guys, apparently scaring the shit out of them; and another blonde guy was sitting in the back of the room with a teddy bear, somehow avoiding all the strife.  And EVERYBODY was yelling or screaming.
“It’s NOT HELLO KITTY, ARU!”
“PLEASE DON’T HURT ME, I’M A VIRGIN!”
“GO AND SURRENDER TO SOMEONE OR ENVENT SOME NEW CHEESE! IT’S THE ONLY THING YOU’RE GOOD AT BESIDES BEING ANNOYING AND DUMB!”
“WHY DON’T YOU GO PLAY WITH YOUR IMAGINARY FRIENDS, SNAGGLETOOTH?”
“I’M THE HEROOOOO!!”
“I despise ALL OF YOU.”
You took a couple steps back, forgetting that the door had closed behind you. Your head hit the wall with a loud SMACK and you let out a yelp of pain. The room was silenced, and every head turned to look at you. You looked back at everybody else, feeling their eyes on you.  Some looked at you with curiosity, others with confusion. You coughed, clearing your throat.
“Uhm… I’m… (FirstName)...” You were cut off by the loud blonde guy with glasses.
“DUDE NO WAY! I TOTALLY TOLD YOU GUYS SHE’D BE HERE, YO!” He launched himself toward you before pulling you into a bone-crushing hug.
“Can’t… breathe…” you muttered.
“AWW SHE’S JUST A NEW LITTLE COUNTRY! ~ she’s so cute and so-” a hand smacked down onto the blonde’s head, causing him to release you. You looked up to see the guy with the choppy blonde hair.
“Please excuse America, he’s…well… America.” He said. “I apologize for his rude greeting. I’m Britain, by the way.” He offered his hand to shake. You reached out to take it, but at the last second, something zoomed by and picked you up at lightning speed. By the time you realized what had happened, the long-blonde-haired man was holding you by your hands.
“Ignore that languid old Britain.  This is what a real welcome should be.” He brought his arms up and spun you around before quickly pulling you close to him. He tilted your chin up and kissed your nose. “Bonjour, I’m France.”
“What? What are you to be doing? You are scaring her, da?” the guy with the scarf stood up. He merely pushed France away and bent down to be face-to-face with you. “You are new country, da?”
“Y-yeah. I think so.” You said, moving your gaze away from the man’s violet eyes.
“I used to be new country once, too. It was awful. Then people died. Then everyone knew who I was and they were afraid of me. Are you afraid of me?”
“Uh… n-not really…” you stuttered. He just stared at you with a creepy smile on his face.
“I like it when people are afraid of me. It makes me joy-smile.”
“Aha, that’s enough out of you, commie,” America said, dragging you in the opposite direction. “Try not to get too close to Russia until you get a little stronger, m’kay? M’kay.”
“I still don’t understand any of this…” You said, rubbing your temples. “Who are you people…?”
“You’ll have time to meet everyone later. Besides, you already met me, what else do you want?”
“An aspirin.”
“Say what?”
“Nothing.”
“Actually, we need to find out more about you,” Britain said as he walked over to you. He was pushing a rolling chair, and signaled for you to sit down. You sat in the chair, and he spun it around so you faced every other country in the room. “Whose little sister are you?”
