Sky-chan: Hello Everyone. This story has been in my mind for a while and I finally got it put up. Also, just for the sake of this story, Nana knows about the mafia, Tsuna also has a cloud flame along with his sky flame, and instead of his main age being 14 it will be 16.

Tsuna: *Looks at script* Why the hell am I a girl again? And why is my name changed to Tsunahime

Sky-chan: I don't know if there will be a future pairing and I don't like to write yaoi. Plus, you would look absolutely adorable as a girl. Your name is Tsunahime because, in my non-expert opinion, Tsunayoshi sounds too masculine. *Quickly runs away.*

Gokudera: Don't worry Juudaime, even if you were a girl, I would still follow you.

Tsuna: G-Gokudera-kun, that really isn't necessary.

Sky-chan: Unfortunately, I don't own Katekyo Hitman Reborn. If I did, there would be an 182769 sandwich going on. *looks away blushing*

Hibari:….You are no longer a herbivore.

Tsuna:….o.O H-Hibari-san.

"Talking"

'Thinking'

"Italian" There probably won't be much/any of this in this chapter.

Sawada Tsunahime hadn't been born an only child. She was the first born of twins. Tsunahime was born, and her brother followed an hour later. The younger of the two was named Sawada Sky. The happy parents were holding their babies when the doctor walked in the room. The atmosphere quickly changed the moment the parents saw the slightly sad expression the doctor had.

Nana knew she wouldn't like the news, but she couldn't stop herself from asking. "Is something wrong?" The doctor looked at the parents. No matter how many times he had given someone bad news, it never got easier. "I am sad to tell you that your oldest child seems to have something wrong with her lungs. The only way to cure what she has it to put her into surgery, but you would have to wait until she is 8 years old. There is a small chance that her body will heal itself, but those chances are very slim." Iemitsu looked at the man with serious eyes. "How long do you think she has?" *sigh* "Honestly, her age limit is only around 5 or 6 years old. If she can hold on until she is around 8 years old, we can fix her lungs. The reason we would have to wait so long is because performing surgery on such a young child is extremely risky. I'm sorry."

The doctor left the room and both Nana and Iemitsu looked down to their newborn children. After a moment, the mother softly smiled. "I'm sure our daughter will be fine. She'll grow up to be beautiful and strong. I'm sure of it." Iemitsu smiled to his wife and gave her a short nod. 'You will be a strong mafia boss someday, Tsunahime. And I am positive that your closest subordinate will be Sky.'

2 years later

Nana watched as her husband played with their children. Despite the fact that the children were only two years old, the children developed very different personalities. Even though they were twins, the boy and girl were like exact opposites.

Tsunahime had short brown hair and big brown eyes. She was usually quiet and shy, but she did have a temper. Tsu-chan, as she liked to call her cute daughter, didn't like to go out and see people. When it came to going to the park, the two year old had taken to staying alone by the swings. Because of her lungs, Tsuna couldn't do too much playing anyway. Nana figured that her daughter wouldn't be able to do much in the mafia if her lungs stayed the way they were, but she didn't mind. The mother thought that if Tsunahime couldn't be a mafia boss, she might be able to stay in a quiet house with her. Unfortunately, it seemed that the young girl's lungs were getting weaker and weaker.

Sky, on the other hand, was completely different. Unlike his sister, his hair was less wild and actually blonde, like his father. To his mother's joy, Sky still had his mother's brown eyes. The boy was loud and outgoing. Sky liked meeting people and loved to play. Whenever they went to the park, the child would immediately go play with other kids. Where Tsunahime was ill and weak, Sky was strong and healthy.

Nana snapped out of her thoughts when she heard a knock on the door. The woman walked over and opened the door to reveal Nono. "Nono-san, it's nice to see you again. What brings you here?" Nono smiled as he entered the house. "I just thought I would come visit you, Iemitsu, and the twins."

The moment Nono walked into the room, both children stopped playing and ran over to the mafia boss. "Gwandpa!" Nono kneeled down and hugged the children. "The two of you are getting better at talking, I see."

After a few minutes, Nono sat down to speak with the parents. The twins were sitting outside. "I see the children's flames are already starting to develop. I noticed that Tsunahime seems to carry both the sky and cloud flame." At that statement, the parent's eyes widened. "I also noticed that she looks more pale since the last time I saw her. She is getting worse, isn't she?" Iemitsu nodded. "Unfortunately, her lungs are weakening. I don't want her to have to be a part of the mafia. I think, out of both of the children, Sky is more suited to being a mafia boss." Nono nodded, and they continued talking about different things, but it was mostly Iemitsu going on and on about how utterly adorable his children were.

1 year later

Tsunahime was 3 when she had her first serious 'attack'. She had been at home with Sky and Nana. Iemitsu had to return to Italy for work. Tsuna had been in the front room reading a book. Although she wouldn't ever tell her family, worrying that they would think she was strange, the girls IQ was extremely high. She was reading one of the weapon books that Iemitsu had brought back from Italy.

Nana and Sky were playing with some of the toys that Nono had given them on his last visit when they heard a loud thump. When they turned around, Tsuna was laying on the floor, breathing heavily and clutching her chest.

The mother's instincts kicked in and she immediately picked up her daughter. Nana ran to the car and gently set Tsuna in the backseat. Sky sat down in the front seat and waited for his mother to get in. It took about 5 minutes to reach the hospital. Nana worried that Tsuna wouldn't make it, but they managed to get to the hospital in enough time to get the sick child into a room with everything she needed.

As soon as the young girl was stabilized, Nana quickly called her husband. Iemitsu ran to the office of his boss and told him the situation. Realizing the seriousness of the situation, Nono allowed the leader of CEDEF to take one of the private planes back to Namimori. It took 16 hours for Iemitsu to reach the hospital.

When the worried father entered the room, he saw his son sleeping in Nana's arms. He turned his head and looked at his daughter. Iemitsu's eyes widened when he saw that Tsuna was attached to monitors and a breathing machine.

The man turned to look back at his wife when he heard her moving. Nana walked over to the other bed in the private room and tucked the boy into the bed. Looking at her husband, Nana couldn't hold back her tears. The woman began crying as her husband pulled her into his arms. "Shh, it'll be okay. I'm sure she'll be fine." Even though he was saying it, Iemitsu couldn't help but feel so much doubt.

"I can't do this. I've watched as she struggled to even play. She can't live normally and I know that she won't be able to make it in the mafia world. I can't watch her die. I wanted to be there for her, but I'm afraid she won't even make it until she is able to take the surgery." Iemitsu watched as he held his wife in his arms. 'I had hoped that I wouldn't even need to suggest this…..but, I can see how much this is hurting her.' "Nana, I have an idea, but it will be a difficult decision."

Nana looked up at her husband and lightly nodded. "There is an orphanage a few towns over. We can drop her off there. It will be difficult, but seeing you like this…I don't want you or Sky to watch as she dies." Iemitsu watched as his wife was trying to decide whether or not they should do this plan. After a few minutes, Nana gave her answer. "One year. That is the time we will spend with her. I at least want her to have some happy memories of us. Let's take her to Italy too. I want her to spend her final days with us as a family happy." The blonde nodded and looked over at his daughter before he mumbled a good night.

10 months later (Tsuna is now 4/let's say that she turned 4 two months ago)

Tsuna had been asleep for almost a month. After she woke up, the girl had to spend another week recovering in the hospital. After she was allowed to leave, her parents started taking the children on trips and having more fun. Eventually, the family went to Italy.

After 3 days, the family went to a park and while Iemitsu was playing with Sky, Tsuna was sitting on a swing reading another one of the books Nana had in her bag about some of the culture of Italy. After a few minutes, the child heard a voice speak in front of her.

"Ushishishishi, (you know who this is :D) what do we have here?" Tsuna looked up to see a blonde boy standing in front of her. His hair was covering his eyes and he was wearing a tiara. From what she could see, the girl assumed that the boy was around her age. "You should move so I can have that swing. After all, I am a prince." Not wanting to do much talking, Tsuna tried to use as little words as possible.

"There are other swings. Besides, you don't seem like a prince." Seeing the boy frown, Tsuna decided to add something in order to make him get his smile back. 'It's strange, but that boy seems like he will be very annoying when he frowns, or hears something he doesn't like.' "You seem more like a king." The smile immediately returned. "Ushishishi, I like you. What is your name?" *Sigh* "Tsunahime. If you want, you can call me Tsuna. Yours?" "Prince Belphegor." "Then…..Bel-kun." Bel couldn't help but blush at the nickname. 'Why am I blushing? It's probably just too hot out here.'

The conversation was interrupted when Tsuna started coughing. After she managed to calm down, the 4 year old apologized. "Since I'm a prince, I order you to come back here again tomorrow." Since this was the first child to show an interest in her, Tsuna nodded. "Alright, I'll see you tomorrow, Bel-kun." A moment later, Tsuna's parents came over to take her back to their hotel. Throughout the next 2 weeks, Tsunahime met back up with Bel. Finally the day came where they were going to return. After saying her goodbye, the family went to board their plane.

'Ushishishi, I've decided. I'll find her again and she will be my princess. After all, a prince needs his princess.'

2 months later

It was painful for Iemitsu and Nana to watch their oldest child slowly die. Over the years, they watched as Tsuna became even paler. There would be times where she struggled so much to breathe that when she finally got her breathing back to normal, she would be asleep for days. The parents worry was finally about to come to an end. It was the day that they would be leaving the young girl at the orphanage. They had called and had everything ready for her to go to the building. As it turns out, there weren't many children there. There were only about 5 others, so they didn't have to worry about there being to many people.

It was a two hour drive to the orphanage. Sky and Tsuna had fallen asleep in the backseat half an hour into the drive. After such a long time, they finally made it to Tsuna's new home.

Nana gently picked up their son while Iemitsu picked up their daughter. The children woke up as soon as they reached the door. The Woman running the orphanage was in her 40's. She had light brown hair with a few grey hairs braided reaching the middle of her back. Her eyes were a dark shade of brown, but Tsuna could see that her eyes were very kind.

"Welcome. I believe you are Nana and Iemitsu? This must be Tsuna." The woman gently patted the young girls head as Iemitsu set her down. After setting her down, the parent's spoke to the woman in a hushed tone then began walking out. This alerted Tsuna quickly.

"Papa! Mama! Where are you going?" They looked at her for a moment then told the young girl that this was her new home. Tsuna felt tears sting her eyes and start running down her cheeks. "Why? What did I do wrong? Please! Tell me what I did wrong! Mama! Papa! Don't leave me!" Tsuna heard as the car drove away. Tsunahime went silent as the woman, Miss Eiko, led her up to her room. The kind woman left the girl alone in order to give her some time.

'Why? Why? What did I do?' Tsuna felt tears sting her eyes again, but she quickly held them in. 'No! I won't cry. Not again. I'll show them. I will learn to fight and become strong. Then one day, I will find them and make them feel this pain.'

Not only was this the day Tsuna was abandoned, this was the day that she found her will to become strong. That day, she shut herself away from everyone, afraid that they too would abandon her.

3 years later

It had been three years since Tsuna was taken to the orphanage, and despite what she did to push herself away from people, Miss Eiko had found a spot in her heart. Ever since that day, Tsuna started training herself so she could become strong. Every chance she got, the young girl went to the library and got books about fighting. Throughout her training, Tsuna would have moments where she would have trouble breathing. Luckily, her body began healing itself. As she got better at fighting, her symptoms also got better. The brunette no longer had such severe attacks where she would sleep for days, but it was clear that one day she would still need to get the surgery.

The seven year old taught herself how to fight in hand to hand combat, throwing darts, and attacking from the shadows. After she was able to move around more, Tsuna found she couldn't stand to stay at the orphanage all the time. Whenever she got the change, the child would leave and no one knew where she went.

During one of her outings, Tsunahime made herself a metal mask. It covered the top half of her face and, although there were no places for her eyes to look out, Tsuna could still see everything. She managed to make the mask so there were tiny cameras that would take in data and show here everything. The young girl also took the time to dye her hair. Feeling so much anger towards her family, Tsuna decided to dye her hair black and change her name. Only the people of the orphanage called her by her real name. She was known by everyone else as Zero.

Tsuna didn't want anyone hurting Miss Eiko, so she began fighting anyone who seemed like a threat in the little town. Just the year before, the brunette had killed her first person. She still hated fighting, but she hated that family more. After the second kill, Tsunahime found that killing came naturally.

Her first year at the orphanage had been spent not speaking at all. After she finally started talking, the girls voice was cold and distant. She used the absolute minimum amount of words to speak.

"Miss Eiko. I will be leaving for a while. I believe I may have found some people who some things about those people." The woman didn't miss the way those people were said with so much venom. "Okay, just be careful." Nodding, the young girl left.

It had taken two days to reach her destination. Having to jump from one plane to another without being noticed was not an easy task. Luckily, Tsuna's clothing did help hide her in the shadows a little bit.

Tsuna was wearing her metal mask, so if anyone did see her, they couldn't get a good view of her face. She had black hakama on. (the black pants from Bleach) Soon after starting her training, the young girl found that hakama were easier to move around in. Her top was a black tank top with another black long sleeve shirt under it. Last, Tsuna was smart enough to know that someone could get her fingerprints, so she wore dark grey gloves and non-slip socks.

The girl was hiding in bushes in front of a large white mansion. According to her research, the place where the information she needed was just above her. Standing under the window, Tsuna got herself ready and jumped into the tree the stood next to the building. After years of training, the young Japanese girl was able to keep silent. Quickly jumping up, the brunette grabbed onto the window ledge and looked inside the room. Seeing that it was clear, the window was opened and the 'shadow' climbed into the room.

The figure had only been going through the files for 5 minutes before she heard footsteps. Just after she managed to pull herself onto the ceiling from one of the pipes, (convenient, huh?) the door opened.

"VOI! Are you sure someone is in here?" "Shut up trash. Of course someone is in here." Tsuna watched as 6 people entered the room. Due to the darkness of the room, the young girl couldn't see the faces of the people in the room. After a moment of the unidentified people speaking, yelling for one of them, one of the men looked right at where the girl was hiding. After they all realized where she was, Tsuna swung down quickly, kicking Squalo so hard he was lifted off the floor.

Tsuna began fighting the people in the room. She was managing to stay on par with the men. Eventually though, due to her condition, the child was captured. After a moment, the girl found herself tied to a chair in a strange room.

"Trash, normally I would just kill you, but I need to know what you needed in that room." Tsuna just turned her head away. They sat like that for five minutes before the man finally snapped. "Listen here trash, you needed something out of that room, and if you don't answer me, you won't be able do whatever you need to." (ooc much)

The quiet girl turned her head toward the man in front of her to show that she was listening. Looking at him, the kid saw that he had what looked strangely like road kill hanging off his shoulder. To his right was a man who had a chain hanging from his eye brow down to his lip. His sideburns seemed strange. To the left of the road kill man was another man who had longish silver hair. There was a sword hanging from his arm. At that moment, Tsuna realized that these people were going to be very troublesome.

"Now, what is your name? Answer quickly trash." "Zero." Someone behind her began to speak next. It sounded like a baby voice, but also sounded like it knew more than a baby normally would. "And what is your real name?" Tsk. "That one can't be answered." "Tell us then, what were you looking for. I don't think you were in there for just any reason." "I have reason to believe information on a certain man is in that room." "Ushishishi, and what makes you think that, peasant?" 'W-wait, that laugh. It couldn't be.' "Just the fact that he is a part of Vongola."

Before they had a chance to ask another question, Tsuna spoke. "I've answered a few of your questions, now can the people behind me please step in front of me? I really like to see the faces of the people I'm speaking to." Road kill man just slightly tilted his head acknowledging her request. After a second, Tsuna's suspicions were proven correct. Unable to help herself, the child blurted out a name that had everyone staring in shock.

"Bel-kun." It went silent for a moment before the prince came out of his shock. "Only one person ever called me that. Who are you?" Since it had been such a long time, Tsuna couldn't help but to smirk. "You already know who I am. If you don't believe me, remove my mask." The fact that she was speaking so casually with a member of Varia was enough to send everyone into shock, but since she was giving permission to look at her face was just mind blowing. Bel stepped forward and removed the mask. The 9 year olds eyes widened. "Tsuna."

"Voi! You know her?" The smile returned to the killers face. "Ushishishi, we met as children. I haven't seen her in years." Everyone looked over at the young girl. "Since she knows a member of Varia, should we introduce ourselves?" After getting a nod from Road kill man, the same person who suggested the introductions spoke. "My name is Lussuria. If you want to, you can call me Luss-nii."

The next to speak was the man standing next to Road kill. "I'm Levi and I am Boss' right hand man." Next was silver hair dude. "Voi! I'm Superbi Squalo!" Squalo was immediately hit in the head with a glass. 'Where did that come from?' "Trash. You're too loud. I'm Xanxus, the next leader of Vongola." After introducing himself, the baby floating nearby spoke. "Mammon." Nodding in acknowledgment, I decided to give my name. "I'm Tsunahime. You can call me Tsuna if you like."

"So, Tsuna-chan, why did you want information on this person?" Taking a breath, I told the people in the room my story. I kept out the name of my former family and the fact that I ever cried. By the time I ended my story, Bel was clenching and un-clenching his fists. Everyone else even seemed disturbed by what had happened. I picked up my mask and placed it back on my face.

"If you don't mind, I will be leaving." My sudden statement seemed to snap everyone out of their thoughts. Road ki…I mean Xanxus then said something that surprised everyone. "Do you want to work for me?" After a moment of silence he continued. "I saw you had some pretty good fighting skills earlier. You could be my cloud guardian. This will also give you a chance to find your father."

After thinking over this for a moment, I nodded. "Alright."

Sky-chan: So how was it? I know it was kind of long but I wanted to get a lot into the first chapter. I was going to put more but then I changed my mind.

Tsuna- Why is my life so sad? And why does my 'twin' have your name?

Sky-chan- This is kind of a sad story, that's why. With the name, I was having trouble coming up with a name and I thought Sky flame, Sky-kun.

Bel- Ushishishi, it looks like my chance of getting the princess are high.

Squalo- Voi! You're a sadistic freak. You won't get her.

Sky-chan- Please shut up. We will see how things go. *pulls out chainsaw* See you all next chapter. Reviews would be great so I know what would make this better for you readers.
