Chapter 1: The Attack on Estraneo 27

Number 27 was a five year old boy who lived in the Estraneo underground laboratory. He was used as a test subject and was being tested on to create weapons to take down another mafia famiglia named Vongola. Everyday 27 suffered through various life threatening tests and experiments. He wondered why he survived though as when the pain became too much his mind would suddenly go blank and he'd hear a voice. A voice that sounded like his but different. More confident.

The voice told 27 what to do and how to survive. 27 asked who or what the voice was but the voice merely told him he was another version of himself. The scientists had taken to calling him 72 since he was the exact opposite of 27. Sometimes when 27 couldn't handle things 72 would push him into a deep sleep and when he woke up he'd be back in his cell covered in new wounds he didn't remember receiving.

By listening to the scientists and what 72 told him 27's body was actually being taken over by his alternate version. At first the thought of another controlling his body without his consent scared 27 (and still did a little) but after a while he realized that 72 was doing that so 27 didn't have to suffer through the traumatic situations.

72 gave off a cold attitude but no matter what he only ever forced 27 into the sleep-like state when the experiments got life threatening. And 72 had yet to give 27 any reason to distrust him. In fact to 27 it seemed like the other was protecting him.

Being locked up in a dark, cold room all alone his entire life 27 began to cherish the other version of himself. 72 had become his first and only friend. 27 cherished him and did all he could to help his other half. It wasn't much since 27 was very clumsy and not very athletic but he did his best and 72 always seemed to thank him for that.

It was the times when his other half thanked him that gave 27 his resolve to live. He wanted to get above ground one day and be free from the Estraneo. He wanted to explore the world with 72. 27 knew it was a childish thing to dream of but he had a feeling his hopes and wishes wouldn't be wasted. Something inside him told him to keep pushing forward. To keep living.

27 was proven right when he was in the middle one of the many tests run by the scientists. 27 had been thrown into an observation room with another child. The other was a boy with silver hair and green eyes. They were told to fight and the boy came at 27 with all he had. Luckily 72 was able to help him and 27 evaded attacks that might have fatally injured him.

The fight had been interrupted though when the ground began to shake violently. The young boys were thrown off balance and a huge explosion could be heard. The ceiling above them shook and 27 looked up just in time to see a huge piece of the concrete ceiling falling and heading right for him. Without his consent though his body shot into action and 27 knew this time 72 had saved him. In times like these when 72 was tired he could move 27's body without forcing him to sleep.

The young brunette lunged forward and the ceiling landed on the ground just inches from where 27 had been standing not seconds ago. Sighing in relief 27 relaxed and stood up. Looking around 27 saw that the glass separating him from the scientists had cracked a little and said Estraneo were gone.

'Get a rock and try to break the glass 27! We might be able to escape!' 72 shouts in 27's head. The brunette nodded and his brows knitted in determination. His dream was being given a chance and he wouldn't let it slip away.

Finding the biggest rock that he could carry 27 picked it up and ran to the glass. Climbing on a huge piece of concrete he was brought to the glass' height. He began smashing the rock at the glass with all his might which due to some experiments was much stronger than a normal five year old should be.

The glass finally gave and 27 beamed knowing with one more strike he'd be able to get out. He held his hand back to hit the glass with all he had but was thrown off the boulder he stood on when another explosion sounded and the room shook once more. The brown eyed boy landed on the ground roughly and groaned.

"A-AH!" A voice screams and 27 opened his eyes when the shaking stopped to see that the silver haired kid who he had been running from just minutes ago was trapped under a piece of the ceiling. From his waist down the kid was covered and 27 knew his legs were probably ruined for life.

'27! Get back to the glass! The ceiling could collapse at any moment! We need to get out of here!' 72 orders but this time the brunette felt as if he couldn't follow his friend's words. Leave another human being for dead? That'd be like doing the same thing that that scientists did to him! Having the opportunity to help another but leaving them to suffer! 'The boy doesn't matter 27! Run!'

"N-no…" 27 whispers as he climbed back on his wobbly knees and crawled over to the young boy who was screaming in agony. "I-I can't do that 72! He's like me!"

'Yeah and he seemed to have no qualms with killing you before!' 72 shouts at him but the other kept crawling to the silverette/

"He must have been s-scared like me! We had no choice but to f-f-fight! The s-scientists wo-would have done worser to us if we didn't!" 27 exclaims as he reaches the silverette. The green eyes were flowing with tears but 27 could see the obvious shock in them.

"W-what are you d-doing!?" The boy shouts as another explosion came and shook the ground. Luckily none of the ceiling fell near them.

"I-I'm h-helping you!" 27 says as he used the boulder on the silverette to stand.

"But I tried to kill you…" 27 looked down at the boy and gave his best smile though he was scared himself. He had to be strong to survive a situation like this.

"We're the same. We didn't choose to fight each other." 27 says as he began to push the boulder with all his might. He managed to budge it with his unnatural strength but it wasn't enough to free the other boy.

'Leave him 27. There is nothing we can do for him.' 72 says in a cold tone of voice. He'd never spoken to 27 like that before so the boy stopped his efforts in shock. Usually the boy was gentle with him but 72 seemed to be mad. Very mad at him.

"No." 27 grunts as he focused on his task once more. "I have… to help… him!" 27's eyes flashed orange and in a moment of what he guessed was adrenaline he pushed the boulder off the boy. Looking down his legs were obviously broken but the silverette looked up at the other with awe in his eyes. Smiling once more 27 bent down and put the boy's arm over his shoulder before lifting him and the boy up.

"W-why would you help me?" The boy asks and Tsuna smiled as he slowly made his way back to the glass. "Y-you should just leave me! I'm not going to make it out! Just leave me you bastard!" He screams and 27 only tightened his hold on the boy.

"I refuse. I… I have the power to help so… so I'll use it!" He exclaims and looked at the other. "I'm going to try and get you up on the boulder. Please help if you can!"

27 then wrapped both arms around the boy's middle before pushing him upwards as best he could. The green eyed boy grabbed at the rock to try and get leverage and help the other. After a few moments of trying he was finally up and 27 followed him quickly as he picked up another rock and aimed to break the glass. He hit it and it shattered into a million pieces. Throwing the rock away 27 supported his companion once more and climbed through the window.

Looking around 27 saw that papers and remains of the ceiling had scattered around the small observation room and the door to the left was closed. The scientists must have run to escape at the first explosion. Hopefully they'd left the door unlocked. Getting down on the ground and doing his best to avoid the glass 27 all but dragged his new friend to the door.

Grabbing and twisting the door knob 27 pulled at the door but it didn't budge. Locked. Putting his companion down 27 began to hit the door with left over wreckage like he had the window. His effort had little effect on the metal door.

"Just give up. We're not going to escape. We're at least three levels underground and if we get spotted a scientist will either kill us or take us away to a new lab." The unnamed boy says and 27 bit his lower lip and he stopped his attacks and looked at the other boy. Of course he'd thought of those scenarios but he'd planned to deal with that when it came. He needed to keep a positive outlook to make it out alive.

"You're really negative." 27 says as he looked back at the door. "72, do you know of a way we might get out?"

"72?" The green eyed boy asks and 27 smiles at him brightly.

"72 is my friend! He lives in my head and is really good at thinking of things quickly. I'm sure he'll help us get out!" the brunette says the other rolled his emerald eyes.

"An imaginary friend isn't going to save anyone, baka."

"72 isn't imaginary! He's real! Even the scientists said so! They named him 72 and do tests on me a lot to bring him out and study him!" 27 says with a pout before smiling once more as he knelt down so he was face to face with the other. "By the way, my number is 27. Yours?"

"Tch," the other boy turned his head away from 27 with a scowl on his face. "59."

"59… okay! Don't worry 59! Me and 72 will get us outta here for sure!" 27 says as he stood and pumped his fist in determination. "72! Did you think of something yet?" 27 asks as he walked back to the door and began his assault on it once more. When no reply came 27 frowned. "Are you ignoring me because I helped 59?" … "Now isn't the time 72! We need to get out of here!"

"He… he's ignoring you?" 59 asks weakly and 27 nodded sulkily. "G…Gomen. It's because you saved me." 27's brown eyes widened in shock as he looked over at the other who wore a blush on his cheeks and an embarrassed scowl on his lips.

"No need to apologize!" 27 says as he hugged the now tomato colored 59. "You're my friend so I'd help you no matter what!"

"…A-Arigato…" 59 mumbles as he relaxed in the other's arms. Not seconds later the door swung open and the two kids jumped in shock. 27 let out an ear bursting screech of 'HHHHHIIIEEEE' and fell on his butt shaking in fear. Looking at the door 27 and 59 were shocked to see a head poke in. It was a boy around their age with black hair and light brown eyes.

Authors Note: So I suddenly got hit by this idea for a story and felt I needed to get it out before I forgot it. I do plan on redoing my other story 'The Truth of the Vongola' so please do look out for that as well. Also I used the shorthands in the KHR fandom for their lab number things… for those who might not know:

27=Tsuna

59=Hayato

72= In this story Tsuna's HDWM takes up a personality so this is him.

They will get their names later on so don't worry. This isn't for the entire fic. Trust me. I wouldn't do that to myself. (I'm dyslexic and while writing this I had to go over it like ten times going 'did I just call Tsuna by Tsuna' and 'I didn't put 27 in place of 72 did I.' Too much brain capacity needed to keep this up for long.)

I do plan to involve Bianchi and Kyoko in the story too since they are Hayato and Ryohei's sisters. I always did love the KHR girls. Though the fighting usually came down to the boys I felt they did play a big part in support. They were strong on their own way and I really respected them for that. There will be no KHR girl bashing here (unless I somehow involves at freakin' butt-face M.M.). No bashing of any characters really… I love almost all the characters in KHR. Even Lambo when he gets annoying.

Anyways please review and tell me how you feel about this story and if it's worth continuing. I'd also like it if you helped me out on ideas for it as well. Ideas for anything really. I'd even like to get some help on adding quirky traits to all the characters~

This is a 1st Gen!Parent and 10th Gen!Kid fic so Giotto and the rest will be included too. I'm too obsessed with freakin' Giotto and the first gen. they're so awesome! Even Daemon! I don't know… I always liked him a little but after the Arcobaleno Arc and his story with Elena… I just love the guy so much!

Please enjoy ᵔᴥᵔ
