Title: The Welcoming Sky
Pairings: No Pairing
Summary: They are twin brothers; one was a teacher, the other a student. He wanted to protect the other from the horror that is the mafia, but the other wanted to help in his brother's growth to be a mafia boss. Tsubasa was Vongola X, while Tsunayoshi was supposed to live a life as an ignorant candidate for Vongola X. Yet the elements of the sky knows their true boss, even when they can't follow him.
Warnings: AU, and I'll add more in the future if there's anything else.

Tsubasa couldn't understand how he got in this situation. It was Reborn who exploded the other five-year old toddler, and it was his older brother who took in the cow-baby. So why was the little afro monster demanding to sleep with him?!

"Lambo-sama wants grape candy, and wants this bed all by himself. You are Lambo-sama's slave, so do as Lambo-sama says." The loud child demanded from atop the bed; jumping up and down for fun.

A loud groan of annoyance escaped from Tsubasa as he searched desperately for a way out of this. Reborn was no where to be found, and Tsuna hadn't came back yet from dropping off that white-haired friend of his. He didn't even know what his mom was doing at the moment, and really didn't want to bother her either.

Looking around his room for anything that could possible distract the hyper five-year old, Tsubasa eventually grabbed a random book. Searching through the pages for a nice, colorful picture he eventually found one that showed the seven flames of the sky. It probably wasn't the smartest thing to show to a toddler, but at that moment Tsubasa really could have cared less.

"Look Lambo, look at the pretty pictures." Tsubasa encouraged; showing the book to the younger boy.

Lambo stopped for a moment, looking at the colorful flames, before grabbing the book and throwing it at the other.

"Lambo-sama, doesn't want a book. Gwahaha!" He laughed; jumping on the brunet and pulling at the other's hair.

Angry and annoyed at the younger child for his abuse, Tsubasa grabbed Lambo and forced the younger boy off him. Not liking the way the other was acting, Tsubasa raised his hand, and began to spank Lambo. The shock of being punished for his actions, and the pain from said spanking, caused Lambo to struggle even harder. Eventually the struggle stopped and the cow-baby began to cry.

Seeing the tears Tsubasa immediately loosened his grip on the toddler, and Lambo took this opportunity to get away from the brunet. With watery eyes, and a shaky voice Lambo tried to calm himself down while reaching for something in his afro. His quiet whimpers to "calm down" failed to sooth him, and Tsubasa raised his hands in slight apology.

"Lambo, I'm sorry but-"

Hearing the voice of the person who punished him, Lambo immediately pulled out a pink bazooka and jumped in; triggering the weapon. Pink smoke filled the whole entire room, and the younger Sawada twin desperately fanned the air around him so that he may breath better. Opening the only window in the room, he waited patiently until all the smoke cleared; revealing another teenager.

"What?! Who are you?!" Tsubasa pointed at the lazy-looking teen.

The other male turned to look at him, and a lazy smile graced his lips. "Yara yara, if it isn't the young Vongola? Or is it Tsuna-nii?"

With lazy steps, the other walked closer to Tsubasa and stared into the other's face, searching for something. After a few moments of awkward silence, the stranger finally nodded to himself and turned away. "Yup, it's the young Vongola."

"Who are you?" Tsubasa asked again, slowly adjusting to the strange situation he was currently in.

"Idiot-Tsubasa, that's the 10 Year Bazooka that brat just jumped into." A squeaky voice commented.

"Reborn! When did you get here? No forget it, where were you when I was looking for you?" Tsubasa asked; nearly hysterical from all of the unexpected surprises that happened so quickly, and the fear of his tutor.

With a sharp kick to his student's head for asking useless questions, Reborn turned back to the pink bazooka and was about to explain further about the weapon, but was stopped by a certain cow. With narrowed eyes and a smug smile, the older Lambo pointed a finger at Reborn and spoke in a confident voice, "Reborn, I, the Great Lambo, am back to take my revenge on you!"

Lazy confidence oozed off the older Lambo, as he quickly threw bombs at the hitman toddler. Without even trying, Reborn smacked away each bombs like little flies and continued his explanation of the 10 Year Bazooka.

"Idiot-Tsubasa, you better listen carefully because I'm not going to repeat myself. The 10 Year Bazooka is a well-used weapon of the Bovino Famiglia. When a person is hit with the 10 Year Bazooka, they will be replaced with themselves ten years in the future. However, the affects of the weapon only lasts for five minutes."

Once the tutor was done with his explanation, he gave one final slap to an incoming bomb at the older Lambo, which detonated. As soon as the smoke cleared from the room, once again, Tsubasa looked up at the older Lambo then back at his tutor. "So, you're saying this person is Lambo, but from the future?" His only answer was another sharp kick to the head.

"Must. Remain. Calm!" Lambo chanted to himself, trying to stop the tears from coming.

Pulling out a pair of horns from his pockets, Lambo placed them on his head and began to ignite flickers of green flames. However, just as he was about to completely charge and trash the room, a voice came from downstairs.

"Taidaima, Kaa-san. Where's Tsubasa, Reborn-san, and Lambo?" Tsuna's asked; voice filtering upstairs.

An excited smile quickly lit up Lambo's face as he unconsciously lowered the horns. Turning around, he was about to exit the room and head downstairs to Tsuna, but was immediately stopped by Tsubasa; who jumped on the teen so that he couldn't move.

"Kaa-san and Tsuna-nii can't find you." Tsubasa said, trying to stop the other from opening the door.

Lambo looked annoyed, and tried to get up but couldn't do to the extra weight of another body. "Come on young Vongola, let me say hi to Tsuna-nii." Lambo tried to reason, stretching out a hand towards the doorknob.

"No!" Tsubasa growled.

"Tsubasa, are you in there?" Tsuna asked from down the hallway, making his way towards his younger brother's room.

"Tsun-" Pink smoked filled the room for a second time, and the weight of a body underneath him quickly lessened. Surprise at the sudden change in weight, Tsubasa got up and stared unseeingly into the smoke. The doorknob began to twist and turn before the door opened, and Tsuna peered into the room. Little arms wrapped around the older brunet's left leg, and Tsuna looked down.

Lambo was clinging onto the other with a strong grip, and he looked up at Tsuna with snot dripping out from his nose. Seeing this, Tsuna quickly picked up the young child and rubbed soothing circles on his back. He whispered quiet words of comfort to the other, before looking in at his younger brother's bedroom; it looked like a bomb had set off with pieces of wood scattered around, probably from the small table that was no longer there.

Not wanting to know what had happened in the thirty minutes that he had been away, Tsuna silently left the room. As soon as Tsubasa heard his brother's bedroom door quietly closing, he dropped his head on the floor. Too embarrassed at his predicament, and needing to think of a way to explain to his brother what had became of his room without mentioning anything about the mafia or the 10 Year Bazooka.

Reborn watched his student's reaction, and shook his head with a slight smirk. Seeing his student wallow in despair over a minor thing meant only one thing to the hitman; he had to train the younger Sawada even harder than before. After all, a true mafia boss can't be stressed to easily.

***Break***

Once Lambo had settled down, the five-year old had take the brunet's bed for his own and was currently sleeping soundly. Seeing this, Tsuna smiled before turning back to his laptop, and resumed what homework he needed done. After two hours passed, with a completed literature essay and a diagram of what seemed to be a science project as the result, Tsuna logged on to his email account.

With quick fingers, he typed in the email address and the password, and scrolled down through the list of his recent mail. Seeing as most were junk mail, the majority of it was deleted; leaving behind only a handful of mails left. Three out of the five electronic letters were asking Tsuna about his health, and how he was doing. The other two were requests, both asking to see him.

Knowing that no good would come from declining from both of the requesters; one because he actually wanted to talk to her, and the other because he would probably still find a way to see Tsuna. Typing an affirmative response to both, Tsuna then logged off of his account and turned off the device.

The alarm clock flashed 11:48 in bright red colors, and Tsuna pressed the bottom that would set his alarm to 5:45 in the morning the next day. With quiet steps Tsuna walked over to his bed, and gently nudged Lambo aside so that he could have room for himself to lay done on. Once he gave most of the pillow to the younger child, he grabbed the blanket and tucked the other in. Incoherent words spilled from Lambo's mouth in quiet slurs before he tightened his hold on the blanket, and Tsuna gave a slight smile at the adorable scene before gently patting the cow-baby's afro.

Laying back down, the tired brunet slowly drifted off to sleep. His tense body relaxed, and his mind wondered to a dreamless sleep.

Tsuna was just tying the last knot to the red bento box before Tsubasa came in from the front door, completely wet from the sweat that was dripping off of him. The younger twin collapsed on the closes chair to him, and when a cup of orange juice was presented to him he immediately gulped it down. Reborn walked in after him, and jumped to a chair that was across from his student.

The matron of the house passed both of the children, toddler and teen, their breakfast before resuming her cooking; happy that she is preparing more meals for more people.

"Tsuna, I want an espresso." Reborn demanded while chewing at the toast that was given to him.

"Hai, hai." Tsuna said, turning to the coffee machine and pouring a cup of espresso.

With hyper hops, Lambo jumped down to the first floor from the staircase and walked into the kitchen. He bounced to his chair, and looked at the older brunet with expectations. Seeing the childish glee in the other's eyes, Tsuna grabbed both his plate and Lambo's and placed them in their proper area. Nana giggled to herself before sitting next to Tsuna, a cup of warm milk in hand; since she'll eat later once they were all done.

She checked the clock and turned to her youngest twin, "Tsu-kun, you should go put on your uniform soon. It's almost time for you to leave for school." Nana commented, the clock striking 7:45.

Seeing the time, Tsubasa stood up from his chair and rushed up to his room; forgetting his exhaustion and the cow-baby menace. While he was rushing upstairs, however, he left behind two of his five toasts and half an egg. Both Reborn and Lambo took the two pieces of toast, and Reborn won the egg from the other. Upon seeing the large, teary eyes that only Lambo can make, Tsuna gave up half of one of his own eggs to the other.

Tsubasa eventually returned, fully dressed, and despaired over the lost of his food before looking up at the clock again. Seeing how much time had passed, he grabbed his older brother by the hand, and raced out to the front yard; dragging Tsuna with him. The remainder of Tsuna's own breakfast was taken by the two toddlers, and Nana could only smile at how energetic her twins were.

The twins were running down the neighborhood, until Tsubasa finally slowed down; that morning's training had greatly reduced his stamina for that day. Tsuna gave a relieved sigh before giving his brother a slight smile.

"I'm guessing you got tired from all that playing with Reborn-san?" Tsuna questioned, noting his brother's obvious exhaustion.

"...Yeah, and I'm still hungry." Tsubasa complained.

Shaking his head at his brother's antics, Tsuna handed his brother the light orange wrapped bento box. Nearly drooling at the food, Tsubasa suddenly stopped and sniffed the air. In a dazed like state, the younger twin began to follow the delicious smell of a meat bun; leaving his confused older brother behind.

Following the smell Tsubasa came across a Chinese Snack Vendor. Not bothering to question why there was even a street vendor in a narrow street between neighborhoods, he walked up to the seller. A young Chinese boy jumped down from one of the chairs and walked off in another direction.

The covered seller looked up at Tsubasa, and the youth gave him a polite smile.

"Can I have one, please?" Tsubasa asked.

With quick hands the owner of the stand gave Tsubasa a warm meat bun, and in return he gave the owner the money that paid for the food. Once the business between the two was done, Tsubasa walked backed to where he came from; only to get lost.

He wandered around, and just as he was about to turn a corner he crashed into somebody. A shriek of confusion escaped from the person, which was probably a girl according to the shrill scream, and Tsubasa immediately stood up to apologize to the other. He helped the girl up, and gathered her fallen bag for her. With slightly narrowed brown eyes, she stared at Tsubasa and gauged out his intentions; once it was obvious that he was being sincere she gave him a smile.

"Thank you for the help, ah! You go to the same school at Kyoko-chan!" The ecstatic girl pointed out, seeing his uniform for the first time.

"Oh, you know Kyoko-chan?" Tsubasa asked back.

"Un, I'm Miura Haru. Who are you?"

"Ah, I'm Sawada Tsubasa."

From there the two talked for a bit, and when it was revealed that Tsubasa still wasn't used to the streets to get to his school, Haru offered to show him. The two chatted for a moment, and as soon as Tsubasa had made it to school grounds they bid farewell. Rushing to his classroom; which he luckily already knew where to find.

***Break***

As soon as Tsubasa had left Tsuna to wander around the older teen could do nothing, but sigh at the scene that had just occur. Normally he would have followed his brother, but the smell of Chinese snacks was far too suspicious to Tsuna, especially with the people he knew. Deciding to walk to school alone, Tsuna moved towards the direction that would lead to Namimori High.

However, after a few minutes of peaceful walking the silhouette of a slender, beautiful woman on a bike came closer to him. At three feet away from the brunet, she stopped and pulled off her bike helmet. A flick of her light pink hair, she threw a can of soda at Tsuna.

Catching it, he looked up at the Poison Scorpion with a raised eyebrow. Did he really look that much like Tsubasa? Tsuna thought quietly, before offering her a smile for the poisonous drink.

She gave a slightly smug smile before riding off. As soon as she was out of sight, Tsuna opened the can and poured the contents out. It wouldn't do if someone else found it and drank it; not to mention if Tsubasa saw him with a can of soda he would want some.

Returning back to his previous task, Tsuna continued walking towards Namimori High. Luckily for him, Hibari wasn't around so he didn't have to suffer for his brother's mistakes. Taking his seat, he saw that Gokudera was already at his own chair. The Half-Italian was watching Tsubasa's seat intently before giving Tsuna a reserved nod.

Yamamoto was sitting next to the bomber with a casual smile, talking easily to his baseball fans and friends. Kyoko was talking to Hana, excited by something that had came up. It wasn't until five minutes before the bell that Tsubasa finally came in for class. He took his seat next to Tsuna, and began to apologize for his sudden departure earlier that morning.

It didn't take long for class to start, and it was soon lunch. Slightly surprised by the uneventful day, for surely there must be excitement following the Vongola Don, Tsuna lead the group of three towards the rooftop. Yet, just as everything seemed to be peaceful and calm there was slight movement from behind the door. With a loud slam the rooftop door was opened, revealing a young Chinese infant with a single braid at the center of her head.

Tsubasa stared at the five-year old for a moment before pointing at her with a hesitant look on his face, "Hey, aren't you the little boy from this morning? The one that left the snack stand when I got there."

"Tsu, that's actually a girl." Tsuna pointed out, opening his bento once he gave Gokudera the red bento box.

"What?!"

"Idiot-Tsubasa, what are you doing? Get up and confront the baby assassin." A squeaky voice said from atop the fence.

"Reborn-san, would you like a piece of my bento?" Tsuna asked, showing his bento to the toddler.

With the promise of good food, Reborn jumped down from his previous position and sat atop Tsuna's head. Watching the way his tutor and older brother were interacting left Tsubasa confused, before he turned his attention back to the little girl.

She was watching them silently before pulling out what seemed to be a folded picture. Her slanted eyes narrowed even further, glancing at the twins before she put the picture away. With a thick Chinese accent she spoke for the first time since her arrival, "Ipin does not know why there are two of you, but I will complete my task from Master."

As soon as Gokudera heard her, he immediately stood up to stand behind his boss. With a threatening glower, he glared at the little girl and pulled out his dynamites. With both teens standing, they covered the shorter brunet; whom was enjoying his lunch with the hitman toddler.

There was no concern on the Chinese girl's face as she faced two opponents, and possibly three if the shorter brunet inferred; after all he did look like her target. Ipin took her stance, and with practiced ease she thrust her right hand forward. Confusion flickered across the other two's face, but soon it gave way to shock as they were raised up in the air and slammed back down on the hard floor. All the while Ipin moved her hands in the directions that the two teens had gone, making it seem like she had telepathic powers.

"Wow, is this a type of psychic show that Tsubasa and Gokudera are a part of?" Tsuna asked Reborn, while clapping his hands together in awe.

"No, it's a martial arts show." Reborn answered while eating one octopus sausage.

"Reborn! Help us!" Tsubasa yelled from up in the air, before being smacked to the side of a wall.

Finishing the rest of the bento with Tsuna, Reborn raised his gun and pointed at the ground between the two teens and the toddler assassin. The smell of garlic powder infiltrated everyone's sense of smell, and the two floating teens immediately fell back down to the floor. Tsubasa pinched his nose closed, and turned to his tutor with a slightly pained look.

"Why garlic?" Was the muffled question from Vongola Don.

A classic gasmask from WWII was on both Reborn and Tsuna's face, as the older teen packed away his finished lunch box. With a squeaky muffled voice, thanks to the gasmask, Reborn explained his reason to his idiotic student who lacked any form of cooking knowledge.

"Ipin compresses the stinky gas from all the gyoza buns she's eaten, and aims it towards her opponent's nose. This causes the brain to become paralyzed, and loosening the muscles to move around freely. This gives the illusion of your body being controlled, and is known as the Gyoza Fist."

"What that was it? Wait! But why did you use garlic?!" Tsubasa insisted.

"Oh, that's because all the seasoning in the gyoza buns become nullified with garlic." Tsuna explained with his knowledge from cooking.

While the two teens, and hitman toddler, were talking amongst themselves Gokudera had turned back to look at the young child in suspicion. The Chinese assassin had fallen silent when Reborn had started explain the secret behind her technique, and was currently looking at the floor in what appeared to be shame. It wasn't until the sun was reflecting across her forehead did he realize something was wrong.

"Reborn-san! What's the brat trying to do now?!" Gokudera asked hastily, moving aside so that the hitman could get a clearer view of the Chinese toddler.

"Oh, she's performing the Pinzu-Timed Super Explosion. It's a countdown that makes her a living bomb, that's powerful enough to make a small crater." Reborn explained, jumping back up on the masked Tsuna's shoulder.

"Wait, what?!" Tsubasa exclaimed.

Ipin, too embarrassed to do anything else, immediately attached herself to the person closes to her; which was unfortunately Gokudera. The startled Italian then tried to get her off him, but she wouldn't budge. Worried for his friend, Tsubasa turned back to his tutor and tried to ask for help.

"She won't stop until she's no longer embarrassed." Reborn simply explained, shrugging his shoulder in indifference.

"That's not helpful!" Tsubasa complained, while standing by Gokudera's side; trying to get Ipin away from the other.

Tsuna walked towards them and kneeled down to Ipin's current level. The older brunet removed his gasmask, and smiled gently at the young child. He opened his mouth, and spoke with calming words, "Are you embarrassed Ipin? But why? That technique of yours, the Gyoza Fist is really amazing. You shouldn't be embarrassed by it, it really is something special."

The countdown on the child's head stopped at one, before being shut down completely. Brought back to her senses Ipin stared up at the brunet, before letting go of Gokudera's leg. She pulled out a picture of her target before holding it to the brunet's face. With sharp eyes she examined the similarities between them; however just as she was examining the two, Tsuna had also caught sight of the picture.

"That's not me." He muttered, slightly surprised by the image.

Reborn presented a pair of glasses, and placed them on the other's eyes. Everything focused sharply for Ipin, and she saw the clear differences between her target and those she had attacked. Frantic about her obvious mistake, she bowed down in apology to all three teens. Gokudera was reluctant to accept the apology, but seeing his boss begging behind his brother's back for the quick acceptance, he relented. Tsubasa himself only accepted the apology because of his brother's obvious like towards the girl.

Eventually, the young assassin headed off; leaving behind the Vongola family, and its two candidate for Decimo.

"Hey, when does lunch end?" Tsubasa asked his brother.

"It ends at 1:15." Tsuna answered.

"Juudaime's Onii-Sama, it's already 1:17." Gokudera said, showing the other his watch.

All color drained from the older twin as he immediately rushed down the rooftop; dragging the other two with him. "We have to go now, or else Hibari-san will punish us!"

AN: I'm so sorry for this late update, I haven't had access to the family laptop for a while now. Anyways, the results are in for the relationship polls: None/No pairings took first place. So the story will have to romance. On to the questions.

Silent. Snow15, I can't answer your question, but I can say that Tsuna is a current candidate for the title. Also, he will be the leader of a mafia family, I just can't tell you which one. Sorry.

27(I'll just continue calling you this; if I may) Byakuran is spoiled. He's used to his tutor paying a LOT of attention to him, so yes he was annoyed with Lambo. Both Reborn and Byakuran won't be interrogating Tsuna because A) Reborn can't show a lot of concern for the brunet even though he wants to, and B) Byakuran won't really bother asking his tutor because he knows Tsuna won't answer him. So his solution is to investigate the brunet's hands on his own free time. Tsuna's cooking is up to Nana's level of cooking. Most things that are at the same level, but there are some dishes that he's better at cooking than her, the same goes for her too. Tsuna does help the guardians, but I can't answer clearly on whether or not they'll like Tsuna more than Tsubasa in the future. Don't worry I like long reviews :)

Because most of you guys were hoping for pairings, I promise I'll make it up to you guys later. Again sorry for the long wait, but please bare with me for a while. Bye, and don't forget to R&R please.
