About 100 years ago before Y/N was born..

Romania's POV

No this can't be happening again..

I desperately looked at the moon for the second time, hoping for some mistake to happen. I saw the glistening moon shined brightly in the pitch black sky and somehow my vision turned all translucent red. This IS the full moon. Kuso, I should've stayed at France's, but stupidly I agreed to buy some to to purée from the shop nearby because I was hungry.

I unconsciously dropped my can of tomato purée and felt my body shuddered, knees onto the ground because of the impact and my once perfectly polished fingernails now have enlarged into thin and sharp ones. The bloody moon's rays bathe onto my body, giving me the surge of a new energy I haven't feel for a long time. My once harmless teeth had turned my canines into long, deadly ones, and becaus eI haven't get used to my vampiric form for a long time, my sharp canine tooth bit my lips like a stinging knife and I let a bloodcurdling howl, and saw the precious blood oozed from my lips and fell onto the moist ground.

My stomach rumbled in anger and instantly my mind blanked and the only image that came to my brain 

Was blood.

Forget the people. I need blood to nourish my hunger... But where should I go?

I snapped my fingers. Of course.

Francis' house.

America's POV

In the world meeting everyone was doing what they were supposed to do when they were waiting for other minor countries.

Playing hide and seek.

"Curse you bloody wander!" Arthur shrieked as the Frenchman found him from his hiding place, the gardens of France's house. The meeting house is renovating, so in a while the meetings will be held on  some random countries once a week. He stomped his foot and pointed his finger at the Frenchman. 

"He cheated!" 

"Now watch your mouth, Angleterre. I never cheat in a game." Francis protested and balled his fists tightly.

"America, do you remember to close the windows and close the curtains as well?" the Briton averted his eyes to his little American.

Alfred rolled his eyes while folded his hands on his chest. Although he acted like a child all the time, getting told to do things twice is not one of his favorites at all. 

"Duh. Of course I did, idiot."

Francis raised an eyebrow."Why are you being so cautious, Angleterre? Vampires don't like the French." he grinned went closer to Arthur's face and he blushed bright red. "N-no it's not like that."

"Then what is it, worrywart?" Alfred asked patted his foster father's shoulders. He knew Arthur for a long time . He even can read what Arthur was thinking and fussing about.  Not to mention he knew that the tsundere had a huge crush with Francis, but this time something's wrong with him. He seemed to be a bit too scared over a so called species called a 'vampire' and 'werewolf'. A few days ago Aarthur had locked himself in his library for days and the last time he came out was for meetings, and now he looked like a complete scaredy cat and Alfred noticed Arthur's once cheerful chartreuse green eyes had now changed into dull ones.

Getting abit washed by his consciousless in reality, he said aloud. "Is it something about those mythical creatures you talked about yesterday?"

Arthur nodded and he was... trembling? Alfred knew that England's suspicious about a so-called theory he calculated, that vampires will be awakened by the 'bloody moon' that happened once every year, 

and unfortunately it is today.

Not that Alfred actually think that Arthur's mind is completely bezerk, but in his place occasionally some UFOs invaded his home and England's, and he was having a pretty hard time getting over it. Like England's, he could also see mythical creatures and beasts, so it kinda makes sense when he talks alone in his sleep.

"F-Francis, what's the time now?" Alfred gulped, feeling the cold shivered down his spine. Something's happening, and it is really bad.

"Oh. It's 11:59."

Francis' POV

Those two words alone had already set the british and the american running for their lives into Francis' house, which left the frenchman spontaneously dumbfounded.

"What are those two are up t-" his sentence hung up when a familliar shade of red illuminated the Earth. For once, he eyes widened with fear and he feel his body weakened just at the sight of the bloody moon.

"*Merde! there's one minute left!" he cursed and raced down through the gardens, and he rubbed both of his eyes.

He is stuck in a maze.

Recklessly without thinking, he rushed into some twists and turns, 

and saw Romnaia with his fully awakened form.

The vampire's once golden eyes now have changed into pitch black, a ring of gold only visible in his black eyes.

Before the Frenchmen could even defend himself, the full awakened vampire decided to make his first move.

With the two men open the entrance to the meeting room with the double doors slamming it's loudest, they saw all the other nations turned their heads 

And their eyes were pitch black with a ring of colour and a pair of long canine fangs dripped with rich blood.

Before the men could even scream the nations pounced towards them

With the last vision of a fully awakened Romania smirking as they were pinned to the ground and before America's eyes were filled with dancing black spots Romania bid his last words with a hand gesture.

"Never underestimate a vampire's speed."
