Chapter 1 - What comes with the pink smoke

The future, The Vongola hide out

At the age of 28 Sawada Tsunayoshi, also known as Vongola Decimo, had mostly managed to get rid of his weaknesses. He rarely screamed in horror, almost never even twisted a brow when he faced deadly opponents. It was also unlikely for him to panic his head off. But sometimes he slipped into his old habits and this was one of those times.

Tsuna stood in the middle of the white basement laboratory in one of his best suits that Reborn had given him last Christmas. He looked like a proper adult who knew how to handle himself. But in fact he was in a huge panic. And he let it show.

Why didn't it work? It was supposed to work! The tenth boss of the famous mafia family thought and gave up completely. He started to pull his hair but resisted the urge to scream. Everything was in chaos. Spanner, Shoichi and Giannini ran around, checking things and Reborn threatened them with a familiar Leon gun. The hitman was angry, angrier than Tsuna'd ever seen before which said a lot about how badly things were. Tsuna wanted to join his ex-tutor but couldn't. It was almost like his brain let him only panic. Why was he still so useless in situations like this? He had to man up now! This was bad, really bad.

"I-I-I'm sorry! I don't know why it's not working!" Irie yelled while kneeling in front of furious Reborn. His hands were crossed in prayer. "The time machine's supposed to carry two persons to the past but now it took only one."

"I know that very well," Reborn said with a seemingly calm voice. Though everyone in the room felt every word inside them twisting like daggers. "So tell me something new, you useless scientist."

"B-But even I don't know, sir! We're trying our best to check if the machine's out of order or if there was a problem with the data we sent."

"Do it and fast." A click from the gun was enough to tell the man was serious. His eyes were shadowed under the fedora.

While Irie ran as fast as he could Tsuna took in a shuddering breath, tried to calm his raging mind and headed for Reborn. He tried to say something as himself, as Tsuna, but couldn't so he slipped into his boss mode, the mode which gave out a powerful aura and sky flames. It was easier that way. "Reborn, what should we do now?" he asked with deep voice. His mind was close to breaking but he knew Reborn wouldn't let that happen. The thought calmed him down a little.

Reborn sighed heavily. It was rare to see him this concerned and Tsuna knew how much the man actually cared despite always showing cool image to the public. "I think there's no other choice but wait."

The brunet gave a small nod. "Was... was this a good idea?" he asked and quickly continued before the Italian had a chance to interrupt. "What if we made a mistake? Maybe he'd be better off here with us where we can see him all the time."

"Dame-Tsuna." Tsuna shut his mouth and looked down. He hadn't done that for a long time either but the situation seemed to take out all his old habits. His old nature which was still deeply rooted inside him. "You know this is the only choice. It's the only place where he can be safe. Hell, it was the most peaceful time ever. No wars, no inner clashing within the Vongola, no ancestor ghosts…"

"I know, I just..." He didn't get the chance to finish his sentence when a long finger pressed against his lips, hushing him.

"Yeah, I know you better than anybody and I know you're having a damn war inside your head." Tsuna bit his bottom lip and dared to glare at the older man. Reborn merely chuckled. "But we'll be both there and he'll be okay with us. And what's the most important is that the enemy isn't there. It's here where we'll hunt them down and kick their asses."

Tsuna smiled a little at that. He knew it was true but worry was his second name. He was still feeling the panic from earlier when he'd realized he wasn't able to go after his little one and make sure he made it safely to the past. And make sure their younger selves knew who the child was and confirm he wouldn't give them too much information about the future.

"He's a strong and smart boy. He'll survive."

"Yeah, and such a kind-hearted one too," Tsuna laughed and felt his body starting to relax. "He'll charm them in no time."

"Just like his father, huh?" Reborn smirked playfully. He had a glint in his eyes that Tsuna recognized easily. He gave him his own trademark smirk back. He'd learned from the best after all.

"I hope you don't mean-"

"Juudaime!" Once again Tsuna was interrupted, though this time it was actually a good thing. He couched into his fist, little embarrassed, and ignored Reborn's knowing smile.

"Yes, Giannini-san? Is everything okay?"

"Yes, Juudaime. No need to worry," the short man said, looking confident. That was enough to let Tsuna relax completely. "We checked the data and young master's arrived safely to the right timeline." Tsuna smiled brightly at the news. Even Reborn put his gun away. "But we still don't know why the time machine couldn't transfer you too."

Tsuna took the information in calmly, back to his normal self now the panic had faded. "I see, I hope you'll find out whatever the reason was and fix it. I wouldn't like it if we couldn't get him back to our time." He gave a sharp look and Giannini laughed nervously, rubbing the back of his head. Somewhere behind them in front of a large, white time machine Spanner and Irie shuddered.

"Of course, Juudaime. You can trust us."

"Good." Then he turned back to Reborn. "You know what to do now, right?"

"Ah, gather the Arcobaleno and find the fuckers."

Tsuna nodded and fished out his phone. Quickly he dialled the number he knew by heart. The phone rang only couple of seconds before someone picked up.

"Hayato. Gather all the guardians into the meeting room right away. It's emergency." He heard only a quick answer before he cut off the connection. Then he started to walk back to the main house.

"C'mon, Reborn. We have a lot to do."

"Hn, who are you to order me around, Dame-Tsuna," Reborn retorted but followed anyway. Tsuna laughed lightly.

"I'm your boss of course," he said with a wide smile he knew annoyed Reborn to no end.

"Shut it, brat. You're way too young to boss me around." His voice wasn't serious though. They had often this kind of friendly arguments.

"That means you're old then."

"Watch what you say or you'll find out later who's old."

"Will I like it?"

"Oh, I don't know about you but I'll be really pleased."

"Then, I'm looking forward to it."

"As you wish, Vongola Decimo."

"…The way you said that sounded really lewd, you know."

"You're imagining things again, Dame-Tsuna."

The present, Namimori middle school, Class 3A

Tsuna saw how the desk came closer and closer. He knew it was near but couldn't stop himself. Then everything went black and right after a loud thumb and an annoying pain on his forehead he woke up again. Ah, damn, of course he had to be conscious and face the torturous event called Nezu's math lesson. Luck just wasn't on his side.

With droopy eyes Tsuna stared at the board for a while until the absurd formula made his head ache and he just had to look out of the window. Haah, much better. Hibird flew high up in the sky towards the roof of Nami-middle. Hibari must be there waiting for the report. Or maybe the yellow bird would just sing him the school anthem while the prefect himself napped under the bright sun. It was such a peaceful day, after all.

Just when he was dreaming of a happy picnic with his friends, far away from Nezu, something happened. He felt it in the air. His hyper intuition told him something would be coming soon. Tsuna didn't know whether it was good or bad something but it definitely knew trouble for him. It wasn't an enemy, right? Was one of his friends in a trouble? No. It wasn't anything like that. But it was big.

Tsuna started to stare wildly around the class room. He was so focused on checking his friends were okay that he failed to notice Nezu's murderous gaze on him.

"Sawada-kun, care to tell me what are you doing? Why aren't you paying attention to the lesson?"

Tsuna jumped and finally noticed his angry teacher. He blushed a little since almost everyone in the class snickered at him. "I-it's nothing, sensei." Was his intuition trying to warn him about a humiliation Nezu was probably planning? No, it was a common occurrence and his intuition never reacted this wildly about it. "I just thought I saw something."

"Hmph, right," Nezu sneered. "I already knew your brain fails you but your eyes too? You really are useless, aren't you?" More people were laughing. Gokudera rose from his seat, raving and taking dynamites out.

"Shut it, you old bastard! Don't you dare to insult Juudaime!" His eyes were murderous and everyone quieted down. Even Nezu looked like he finally understood the threat Gokudera was to him. Still that wasn't enough to stop him anyway.

"S-Sit down, Gokudera-kun! I won't take that kind of att-"

He never got to finish his sentence when that something, which Tsuna'd felt, finally happened. It came in a form of pink cloud that appeared in front of the class out of nowhere. Everyone else looked at it like it was some kind of magic trick but those who had seen the power of a ten-year-bazooka knew right away what the cloud meant.

"What is it?"

"Where did it come from?"

"Hey! It's fading?"

"I-Is there someone stading in the middle of it? Where did that person come from?"

Tsuna panicked, his alarms going off. He saw from the corner of his eye how Gokudera'd paled and Yamamoto had an unusually serious face. In their experience time travel meant only two things: either it was an adult Lambo but now a child Lambo wasn't anywhere to be seen nor was the bazooka, or then someone came from the future using their time machine. And last time when they'd gone to the future, it wasn't a good thing.

It was bad and so was this.

Yamamoto drew his bamboo sword out, ready to use it if necessary. Gokudera kept his dynamites out a little longer. Tsuna on the other hand panicked inside his head. What if it was an enemy? What if it attacked? Everyone would get caught into the fight and find out about the mafia! He couldn't just go into the dying will mode in front of everyone, right? But he still wasn't good at fighting without his dying will. Heck with it, he didn't even like fighting in the first place.

What to do, Reborn?! Tsuna ruffled his hair and couldn't look. But he had to open his eyes when he heard surprised whispers and loud yells of delight. Delight? What the...?

Tsuna didn't expect to see what he saw. That option hadn't even crossed his mind. In front of the class stood a small figure, a boy with ruffled dark brown, almost black hair and brown eyes. The boy was so small he didn't even reach the teacher's desk. Also, what stood out of him was that the kid wore a grey suit jacket, orange tie, grey pants which reached his knees and long black socks. He also looked around with surprised but curious eyes, taking everything in.

"Aww, he's so cute~"

"Where did that kid come from?"

"Where are your parents, little one?"

"Ahaha, he's blushing."

The boy was beat red from all the attention he got. He looked like he wanted to hide behind something but still stood there, braving himself to look at everyone. He was quite a brave boy. If it were Tsuna, he'd have run from staring strangers when he was that age.

"Tsk, another brat," Gokudera sheeted and put his explosives away. The younger boy moved his gaze to the new voice, jumped up like he was surprised and when everyone expected him to be frightened of a scary looking delinquent he did exactly opposite of everyone's expectations. He ran straight to Gokudera while giggling like Gokudera was the best thing he'd ever seen.

"Zio Hayato!" Then the kid hugged Gokudera's legs and didn't let go. The bomber on the other hand froze from the shock. He just stared at the little creature that hugged him tightly, like it was some kind of UMA. Everyone assumed it was because of the surprise the temperamental teen hadn't kicked the kid off already. He didn't like children after all.

"Haha! Do you know this kid, Gokudera?" Yamamoto laughed like nothing unusual happened. Tsuna had to second the baseball player's question, though. Maybe the child was someone Gokudera knew, maybe from his previous family before he joined Vongola since the boy seemed to know him.

Gokudera didn't look like it though because the next thing he did was shake the kid off (which didn't happen easily since the child was almost like glued to him) and shout at Yamamoto, "Shut it, baseball-freak! Of course I don't know him! He just came out of that pink cloud, you idiot, which means he time travelled!"

Tsuna facepalmed and then rose his head in horror. Gokudera had just talked about time traveling in front of the whole class which was full of non-mafia-related occupants.

"You're funny, Gokudera," someone laughed at the back of the room. "Time travelling? Good one!"

Tsuna let out a sigh of relief. They didn't believe the bomber. Of course they didn't. Time travelling was absurd to those who hadn't experienced it themselves.

But now the question remained, who the kid was and why was he here in the first place?

The unknown child from the future looked a little disappointed when his Zio Hayato (whatever that 'zio' part meant, Tsuna wondered) had kicked him off but in couple of seconds looked like nothing had happened. He smiled again widely, cheeks pink, and patted Gokudera's knee.

"It's alright, zio Hayato," he said and got a raised eyebrow from the said teen, "You're in one of those moods right?"

Tsuna didn't know should he hide or laugh. What the kid had said was really funny especially when you got to see Gokudera's wide eyes and gaping mouth. Though he wanted to hide since this knew a huge storm.

The child seemed to know it too since he moved on to Yamamoto before anything grand happened."Zio Takeshi!You're here too!"

Yamamoto just laughed and patted the fluffy head. "Yup, I'm here, kid," he said and looked like he knew him. Though everyone knew he definitely didn't. He was just like that. Friendly and accepting from the beginning especially if the other one was just a child.

"Can you give me a piggyback ride? Please?" Everyone cooed when they saw doe eyes that looked up at the black haired teen. Yamamoto just smiled and took him up to his back. The boy laughed like he was really having fun as well as Yamamoto was. Tsuna noted that the girls in the glass looked ready to jump on Yamamoto. He was a perfect dad candidate. He liked kids, was polite, cheerful, athletic and absolutely handsome. The future boss sweatdropped. How to save his friend from hungry fangirls?

"Don't carry that brat so casually!" Gokudera was back to his senses. "What if he's dangerous! Don't you dare to take him to Juudaime!"

"What do you mean, Gokudera? How could a child be dangerous?" Yamamoto continued carrying a giggling child around the classroom. That went on until they stopped in front of Tsuna. Gokudera was raving in the background, trying to make his way to his dear Juudaime.

For some reason Tsuna felt nervous when he saw the child from the close distance. The child had also stopped giggling and looked at Tsuna with calculating eyes, like he wasn't sure about something. "Kid, this is Tsuna. He's my friend," Yamamoto introduced.

Silence followed that. Tsuna looked at the brown eyes which were a lot like his, only not as wide. They were wide alright, but differently. There was a weird sensation inside the young Vongola, like he knew the boy yet he'd never met him before. He shook the feeling off and smiled a little since the child was still looking at him like a hawk.

That made a trick, understanding took finally over the child's face and he smiled back. He jumped off of Yamamoto's back, sidestepped him and jumped straight to Tsuna's lap hugging him even harder than Gokudera just a while ago. Tsuna felt his face heating up from the affection boy was showing him. Distantly he heard the class whispering and mutter curiously and Nezu-sensei spluttering the class to get back to the order. It was all in wain, though. Tsuna's – as well as everyone else's – attention was on a fluffy main of hair.

"Watch out, Juudaime! He might have a weapon with him-!"

"Tou-chan!"

Everyone froze.

"Tou-chan, you're here too! Just like you said! I was so scared! Ne, ne, zio Hayato is being funny-"

But Tsuna didn't hear the rest. Suddenly everything went black as he fainted from the shock.

Tou-chan?

HE WAS TOU-CHAN!

Zio = Uncle

Tou-chan = Daddy/Dad

A/N: About zio. It's Italian and means uncle so the little one's calling Gokudera and Yamamoto his uncles. Hayato understands this since he's Italian but Yamamoto and Tsuna have no idea. First I thought about calling them Hayato-nii and Take-nii but they're not quite big brothers for him. Then uncle in Japanese doesn't sound that cute and makes them feel old (or at least it'd make me if I was under 30 and someone called me baachan... oh god no). Then I understood. The kid's bilingual so why not use Italian. I actually studied a little Italian for this.. Then I thought about calling Tsuna just daddy but I kinda want to emphasize how the child knows both Japanese and Italian and in later chaps I think it's important so. Yeah! :D

Why's the English in this fic a little awkward or too formal? Why're there stupid grammatical errors? So, if you're interested in betaing, I welcome you with open arms and cookies. (I warn you though, I'm a slow updater since I'm in Uni and all)
