Welcome to my fanfiction! I got inspired by the opening song of one Thai drama. The drama was about twins, the younger born disabilities which he can never stand up on his own with pain running up his legs and spine. And so I got this idea if Tsuna was to have a twin who is like this, would he be like the older brother in the story? The brother who was only understanding and loving to his family. He became the head of his family at a young age after his father disappeared. I hope that you will enjoy reading this story of the sky twins. Tsuna and Natsu will be five years old at the beginning of this chapter before growing up into their teens years (15 years old).

Chapter 1: The Start of Our New Journey

In the household of the Sawada, there lived four members that are known by everyone in Namimori. It was just another peaceful night for the family that is now sitting down in their garden eating dinner. The father, Sawada Iemitsu, beaming like the idiot he is after he had finished showing them some magic tricks, now reaching over to pick up his violin. "Now that that's over let's do a little concert for you dears. Are there any songs that you would like to request for me to play?"

Turning to face his oldest son, Sawada Tsunayoshi, five years old who is bouncing in his chair reflecting his father's smile. "I want something soothing and calm."

Iemitsu nod in approval facing his the other little brown hair boy next to Tsuna sitting in a wheelchair looking as excited as his counterpart. "And what would you like to hear, my young master?" The blond bowed before his younger son, Sawada Natsuki.

"Hm...Beethoven, please!"

"Ah, great choice," he said before walking to his smiling wife, Nana, who sitting on the other side of Tsuna. "And you, my lady?" She blushed knowing already what she was going to reply, "I love all your songs so any is fine."

The twins were whispering to each other about the music and giggled. Iemitsu walks to his little 'stage' and spoke again. "First I will be playing the song your mother loves." He then readied the bow across the strings and soon began to play a love piece that he composed just for her.

'Daddy's really good with the violin. He's even playing that pretty song for mommy he played when he asked her to marry him. Nakkun wants to play that song too someday.'

The next day, Natsu tried to imitate what his father was doing while playing the violin. Iemitsu walk into the room hearing sounds of violin, watching him doing his best use his tiny hands hold the instrument. Chuckling he went over to the little sunshine asking, "My little Natsu, do you want to learn how to play the violin? Papa can teach you if you wish."

Natsu and Tsuna looked up. "N-Nakkun can?" said the shorter twin as the other smile happily for his brother being able to do something he loves. Watching him is fun enough and seeing him find something he enjoys doing already brighten up everything.

"Of course you can! With just a little courage and determination, Natsu and Tsuna can do anything!" Iemitsu took out another violin from out of nowhere and showed him how to properly hold it.

"O-ow. I-it hurts daddy." Natsu said when he nearly cut his hand on the thin strings. Iemitsu then tried to get his fingers positioned in the right spots understanding the pain.

"You'll get used to it. It's alright, Natsu." the man said as Tsuna stared at them curiously. From far away Nana glanced at her family with a worried look.

That night

While the two children slept, Nana looked at her husband, her eyes filled with worry. "Iemitsu, please don't force Nakkun with the violin. I-I don't want him to feel bad if he can't do it."

Iemitsu shook his head gently. "I'm sure that he'll be fine. Nana, don't worry too much." He wiped his wife's tears trying to calm her down. He doesn't know how long it'll last before he has to leave so teaching the boy might be the last thing he can do for now.

Iemitsu was packing for his return to work. He looked at his sons and smiled proudly at them. Tsuna was helping him pack his things while Natsu was looking at his brother with a guilty and sad expression on his face.

"N-Nakkun's sorry daddy. T-that Nakkun can't help you pack." Tsuna looked at his brother as Iemitsu gave them both a hug.

"Daddy's happy that you're here and that's all there is to it." Natsu perked up at that line and forgot his guilt immediately.

The twins walked with their father to the door as Nana join them, smiling a bit sadly. Giving each of them a hug and whispering a soft "It's alright. I'll be back" to Nana kissing her fondly smiling.

"Daddy here, get on the plane!" Tsuna exclaimed, pointing at the toy plane on Natsu's lap.

"Yes, I should. Oh wait." he jokes before laughing. "Tsuna got me again." His laughter eventually trailed off and became a gentle smile. "Tsuna, protect your younger brother and Mama okay? Natsu, practice a lot then daddy will come back and teach you even more."

Kissing his twins' foreheads and giving Nana an apologetic glance, he left out the door.

A Month Later

Tsuna was helping his brother walk down the stairs to his wheelchair. It was nearly time for breakfast and he looked at his mother expectantly. "Mama let's eat!"

"Of course Tsu-kun." Tsuna finally arrived at the bottom and helped Natsu into his wheelchair. He pushed his brother to the table before taking his own seat. Nana soon placed plates of food for both her sons. Staring at her younger son as she asked quietly, "Nakkun, do you like playing the violin?"

"Yeah!" he nods smiling. "Nakkun loves the violin!"

"Tsu-kun loves when Nut plays the violin!"

Nodding at their answer as she looks down sadly. The twins look at each other before nodding and quickly finish their food. Tsuna and Natsu hurried to the next room as Tsuna gave his twin his violin. He took a deep breath, then started playing a song. The same song that their father composes for their mother and the one he had been practicing since that night.

Nana ran to the living room thinking that her husband was back but saw that it was just her younger son playing the violin. Tears fill her eyes as she watches the scene of her younger son playing the violin.

"Mama, what's wrong?" Tsuna asked his mother, who was on one knee.

"Mama?" Natsu stopped playing to look at her.

"M-mama just thought of daddy and missed him," Nana replied.

"But Tsu-kun/Tsu-nii and Nakkun/Nut is here," the twins said together in unison.

"Yes. You're both right sweeties. Mama has Tsu-kun and Nakkun, don't I?" she smiles sweetly and quickly wiped her eyes dry. 'I can't be sad just because he's not here. Beside these two angels are with me.'

"Thank you. Thank you for being here. For being born." the twins were confused as to why she was thanking them but guessing that they did something great was all it took to make them smile.

"Yeah! We love you!" Giving their mother a hug with a beautiful smile on each of their faces.

"Tsu-kun! Time to get up!" Nana yelled for her son, a loud thud signaling that he fell off the bed. "Okay, Mom!" He yelled back a moment later shaking the sleep out of his head.

Tsuna looked at the clock, which displayed 7 AM in bright red numbers, and realized he had an hour before school started. It had been about 10 years since their father had left. No one heard any word from him - he just...disappeared but money would be sent constantly to their account. Nana had taken good care of them and the three were content with their quiet and peaceful life even with the missing member.

Tsuna got up and changed before heading to the room across from his. His younger twin brother, Natsu, laid there. Smiling to himself, he gently shook his brother awake. "Natsu, time to wake up."

"Mmm..." came the cute sound from the younger twin whom peeked out of his cover and sat up hair still messy. "Good morning Tsu-nii."

Tsuna continued to smile at the shorter younger boy with the same face as his. No matter what, Natsu would be his baby brother. No matter the age or situation, Tsuna promises to be there for his family and protect them. After all, he's now the head of the family since his father disappeared.

Handing Natsu his clothes and helping him change, Tsuna helped support his brother to the stairs, as Natsu would beg to walk down by himself. Tsuna was naturally a step behind in case of Natsu tripped.

Nana looked at the two, waiting for them with Natsu's wheelchair. She reminisced about their growth. Tsuna had hit his growth spurt at age 14 - last year in fact. He was taller and no longer tripped over himself (for the most part), a habit he developed after Iemitsu left.

He had become self-sufficient because he knew. Knew that she had to be with Natsu more, and he understood that. Thinking about all the past years had made tears fill her eyes. Tsuna had been the greatest son she could ask for. Never complained that he wasn't getting the same attention that Natsu got or that Natsu wasn't like any other normal boy. She couldn't ask for more than this.

Nana turned to her younger boy, who looked like he was in pain coming down the stairs. She wanted to rush to him and just carry him down but she knew that he wouldn't want that. He wanted to do this for himself and be more independent.

Natsu was shorter and weaker than Tsuna but was, in turn, smarter, even called a genius by most who knew him. Nana didn't care what people said but she still worried that Natsu would be hurt by all the comments people made about him behind his back. She thought both her sons were perfect the way they were. Both of her sons were strong. Stronger than anyone she met in her life.

"Mom?" Tsuna snapped Nana out of her thoughts.

"Ah, sorry Tsu-kun." she smiled as Natsu pushed himself to his spot on the table, the food laid out looked good as ever. After serving the 2 teens their breakfast, she went outside to check the mail. A note was hidden in the stack of normal mail, and it stated something rather... interesting.

Raise your child to become the next generation's boss.

-Reborn

Her sons were smart but she felt like they're missing something. Something that this "Reborn" person could help with. Natsu went to another room to start studying after Tsuna had left for Namimori High, Nana decided to give a call to Reborn. From a tree nearby, a baby in a black suit was holding a green phone. He smirked, looking at the info on Sawada Tsunayoshi and Sawada Natsu. Just as planned.
