Summary: After finding a child abandoned in an alleyway, of course, Gilbert couldn't resist the urge to take the child with him. The thing is, the child is (unknowingly) one of the candidate to be Vongola Decimo! Not to mention, five years old very very cute kid didn't quite mix with century years old mans that has gone through more wars than anyone could imagine.
DISCLAIMER: I DIDN'T OWN HETALIA AND KHR, THEY BELONG TO HIMARUYA AND AKIRA-SENSEI, RESPECTIVELY.
Chapter One: Gilbert, you need some mental assistance.
You see, one thing that all nations should have learned in their centuries long life is that they should never make more relationship than necessary with humans, as unlike them, humans will age and die, while they will continue to live as long as their nation stand, as long as their people still exist.
And that's one of the reason why Gilbert Bieldschmidt, the personification of the Kingdom of Prussia, feel conlicted about the kid he was talking to right now.
"So, you come to Italy with your daddy, mommy and brother, but they left you here alone without coming back for ten days already?" Gilbert asked, trying to conclude what the kid had said, it's very fortunate he has some language advantage, or else, he won't understand a single Japanese that the kid had said.
The kid nodded sadly, "Yes."
Now, despite being a genius in war strategy and some other fields, he is quite awkward with peoples, not to mention he has distanced himself with humans for the last few centuries, so... yeah, he has to admit he is unawesome right now.
"Uhh, maybe you could go to my house?" Gilbert asked, unsure about this himself.
The child brightened up slightly, "R-Really?"
Gilbert nodded, "Yeah, and if your family didn't come to you, maybe you could live with us..."
Damn, he just making a very dangerous move there.
Okay, he has a soft side for childrens, that's true, even in war, he will try to kill those who are still young as painless as possible, a contrast with his usual torturous method of killing when he was facing enemy who he has deemed old enough. But really, why does he feel the strong urge to take the child and put him into safety and comfort?
'Damnit, I had gone soft.' Gilbert cursed as he walked with the child to Feliciano's house.
As he walks, he began to wonder, has he gone really softer?
Maybe, after all, he hasn't killed any human for around 20 years, and his relationship with Feliciano has helped both of them to melt the ice that has turn their heart cold for centuries, making them more human, the same apply to other nations who are in happy relationship, like Matthias, Ivan, and some others.
'I guess, love is really the best cure, huh?'
He cursed himself silently for thinking of such a cheesy line, and how unawesome it was for him.
"Uhh, mister, why your face looked scary?"
Gilbert snapped out from his thought when the kid said that.
"Huh? Oh, don't worry, I'm just thinking. By the way, what's your name?" Gilbert asked, realizing he still yet to know the child's name.
"M-My name is Tsuna, Tsunayoshi Sawada... what's yours?" 'Tsuna' asked.
Gilbert grinned, "Kesesese~, my name Is Gilbert Beildschmidt."
Tsuna nodded, a smile decorating his face.
'Damn! This kid's smile is so fucking bright and cute! I bet he could light the entire town with it, while taking over the world with his cuteness!'
He just noticed how cute the wide, innocent and warm brown eyes that currently stare at him, it's amazing how a kid who had been abandoned to be able to be this cheerful, and the way that the kid smile has make Gilbert think that the world is still a good place after all.
When he felt a tug in his long sleeve, he looked to the kid once again and ask, "What?"
Tsuna smiled and pointed at a place, "Look! It's the colosseum!"
Gilbert looked and indeed, it's the grand colosseum, where as Feliciano has told him, mighty gladiators has fought for their life there.
He remember Feliciano's cringe when they went to Colosseum for the first time together and he jokingly ask, "Have you ever been in the ring?"
He was surprised to find out that the answer is, "Yes, yes I had, Grandpa throw me to the ring to fought a lion once, and it was when my physical body is still around nine years old, I still have the scars from that day."
He decided to didn't ask anything else when he see his boyfriend's eyes darken at the memory, he found out about the scar exactly the night after that when they had sex for the first time with each other.
Flashback...
"This..." Gilbert traced the scar that decorated his Italian lover's body.
It's very obvious it was made by an animal with a sharp claw, and after finding out about what had happen, he was sure it's from a lion.
All nations are very conscious about their scars and other things like tattoos that decorated their body, to the point that if they go out in public, they would make sure they wore long sleeved clothes to hide their scars.
"Yes, it's what I'm talking about earlier, ve." Feliciano confirmed.
"I think it's the biggest scar you have." Gilbert stated, seeing no other scars that are as big as the scar from the lion, as mostly the other scars are either bullet scars or some small scars.
"In case you forget, I still has the scars in my back from when I was tortured after being caught in World War 2, remember when I try to escape after my peoples are turnig away from the Axis?" Feliciano asked.
Gilbert cringed slightly, "Yeah, I still remember, Lars told me that Luddy is in some kind of depression from the guilt after the war."
"It's a good thing he is better now." Feliciano said, before kissing his lover's lips.
Apparently, they had agreed to take turns in who top, and Feli has very fortunately got the chance to top in their first time.
Flashback End...
"Mister, may I ask where's your house?" Tsuna asked to the red-eyed man.
"My house is in Germany, but here, I stay at my partner's house, and we are only three house away from it." Gilbert stated.
Tsuna began counting the houses, and when he see the house that's three house away from them, he beamed.
"You has an amazing house, mister Gilbert!" Tsuna praised.
"Actually, it's designed by my friend along with my partner, so I'm only live there." Gilbert said to the brunette.
"Oh okay, but... is your 'partner' is like you're daddy and your partner is mommy?" Tsuna asked, curiousity evident in his youthful eyes.
Gilbert scratched his cheek awkwardly, "Actually, if anything, we're both daddies."
"Eh?" Tsuna said,tilting his head slightly, confused on what that mean.
"You will see later." Gilbert replied, ending the coversation just when they arrived at the gate of Feliciano's house.
Gilbert took out the key and opened the gate and closed it after both he and Tsuna has went inside.
Gilbert used another key to open the house's front door and exclaimed, "Kesesese~, your beloved awesomeness has come home!"
"Ve~, Gil, you should really try to find a less noisy way to enter someone's house, even if you live there..." The Italian scolded when he come to the hallway wearing only some sleeveless shirt and shorts, looking like after waking up from a siesta.
"No way! It's the most awesome way to enter a house!" Gilbert laughed before he kissed Feliciano in the lips.
"Wait, I think I forgotten something important.." Gilbert said, breaking out from the kiss.
Gilbert's eyes widened when he see a certain kid standing behind him with his hand covering his eyes.
"Mister Gilbert? Have you finished?" Tsuna asked, with his hand still covering his eyes.
"Eh, uh, ah, y-you could open your eyes already." Gilbert said awkwardly.
Feliciano just stared at the boy as Gilbert talked with the boy.
The boy really remind him of someone back at 1600's, a blonde man, with blue eyes, a very similar tone of voice, if not deeper because of the age difference.
"Eh, so you're North Italy? I hope we don't gave any trouble to you and your brother! My name is Giotto!"
"Ve~, just do your best! I know you will make an amazing family, and your legacy will be remembered among the mafia world for a very long time."
"Thank you!"
"And could you please defend the Tri-Ni-Sette that me, my brother and Kawahira has entrusted you with?"
"I'll do my best."
He didn't make much connection with mafia world anymore since Giotto passed away, and he already has Kawahira and the Cervello to look over and passed the Tri-Ni-Sette down, so he don't really mind, and the only proof he and his brother is once in the mafia is for their ability to use flames, but it remained a secret even among nations.
"Feli, Feli!" Gilbert called him out of his thought.
"Uh, yes?" Feli said awkwardly, feeling very dumb for spacing out.
"I just asked you, since I met this Tsunayoshi kid in the street saying that his family left him there, I want to ask if you're okay with him here." Gilbert said, putting his hand on Tsuna's head.
Feli looked at the child once again, seeing his pleading look, and he know that the child is very innocent, and really is someone who need help and warmth.
He then looked at Gilbert who stared at him expectantly.
He know, that if Gilbert do something like this, that mean that he has resolved himself, and he know that even if he say no, Gilbert will find a way to keep the kid.
Feliciano sighed, "Fine, but-"
"Thank you, thank you, thank you!" Feli was cut off when Tsuna jumoed and crashed into his body while thanking him loudly while Gilbert is laughing.
For some reason, Feliciano feel happier already and returned the hug and laughed, "Fine, fine, welcome to the house."
Tsuna grinned happily, feeling very happy to find a home after he realized that his 'family' has left him alone.
Then, Tsuna realized something, "So, I has two daddy?"
Both Feli and Gilbert stared at each other and laughed, "Yes, yes you do."
"Great!" Tsuna exclaimed.
Chapter End!
Woohoo! This is the first chapter of the story, and please note that this is an AU, so the Nations past and personality is altered, along with their physical body.
Example: Feliciano is buffier and more muscular, he also has some scars and tattoos in his body.
Oh, and Kawahira and The Italy Bros know each other.
