Chapter 1 : Introductions

His name is Sawada Tsunayoshi, the Vongola Decimo. Well no need to add the last part since he didn't really like being so formal. But anyways, he was the boss of his 7 other Guardians; Storm, Rain, Lightning, Sun, Cloud and Mist Guardians.

And if there was one thing certain he hated about being part of a mafia family, is the paperwork. Another loud boom echoed outside the hallway. He was sure he heard a vase break outside the doors of his office.

He groaned as he knew it would add up to the number of paperworks on his desk. Well, more precisely, on his sofa. It had piled up too much on his desk that he told Gokudera to put the rest of the paperwork on his sofa.

"Kufufu~ I didn't know you enjoyed playing with me so much, Skylark-kun~"

"I'll bite you to death!"

He sighed, he knew he shouldn't have sent his Cloud and Mist guardians on easy missions that would've caused them to meet up as they were gonna give in their reports to him. Oh well, too late now.

He continued doing paperwork until he heard the explosions and clashing metals stopped. He looked up to find Mukuro and Hibari on the floor, holding their stomach as if they were in pain -no, is- and Chrome being in the middle between them with her trident in hand. It seemed she had given them stomach-aches like how women get when they have their periods.

"Tadaima, Bossu." Chrome greeted.

"Okaeri.. I suppose your missions went well?"

"Hai." Over the years, Chrome had become less shy and much stronger in illusions than before.

"KufuFU!.. My sweet Na-GI!.. Please take away this illusion!" Mukuro pleaded to her.

"Omnivore.. G-get rid of this. NOW!" Hibari said as he glared up at the illusionist.

Chrome pretended to think about it then smiled, "If Bossu wants me to."

The two men looked over at their boss with a 'Tell her to stop now or else' look. Tsuna sighed then said, "Please release the illusion from them, Chrome."

And Chrome did so. Mukuro and Hibari let out a breath they had been holding since they came in then stood up straight.

"Now, before you two give me your reports, please do not make anymore mess. I'm tired of all these paperwork so I'm giving you three a fair warning. Understand?" Tsuna glared at them.

The three nodded their heads and quickly handed in their reports. "Okay, you all are dismissed." And with that, the three of them walked away.

Tsuna sighed, he wondered where was Re-

"ACK!" Nevermind. He rubbed the back of his head and looked at the smirking infant who had successfully once again, kicked his student on the head by surprise. "Reborn!"

"Dame-Tsuna, despite you being the Vongola Decimo now, you still need more training." Reborn smirked sadistically.

Tsuna glared at him and said, "I'm already getting incoming paperwork from what happened this morning. Don't treat me as your toy Reborn!"

"Who said I was treating you like a toy? You're of course my to- I mean student. You have a long way to go still." Reborn coughed.

Tsuna hummed in annoyance then continued doing paperwork until that is, Reborn said something. "Oh yeah, Giannini, Shouichi and Spanner wants to see you in the training room."

Tsuna looked up at him, "Eh, why?"

Reborn smirked, "Who knows. Now don't be late or else I'll shoot you." He pointed a gun at Tsuna.

He let out a girly shriek that had somehow stayed with him all the time and quickly ran out the door. He was still scared of Reborn. Who wouldn't be? He's practically the strongest hitman/baby alive.

Tsuna walked into the training room and saw the three mechanics with the Ten-Year Bazooka. He raised an eyebrow, 'What are the three doing with it now?' He walked closer towards them until they noticed and greeted him.

"What are you doing with Lambo's Ten-Year Bazooka? And does he even know you three have it?" Tsuna asked.

Shouichi rubbed the back of his head, "Well kind of. But anyways, thanks for coming Tsunayoshi-kun. We actually need some help."

"Help? What kind of help?"

"Ah well.. You tell him, Spanner." Shouichi looked at him.

"Well... We modified the Ten-Year Bazooka a bit but we need someone to test it."

"Oh okay.. But what does it have to do with... Oh."

"Is it already, Jyuudaime?" Giannini asked nervously.

Before Tsuna could say anything, Lambo ran in with Gokudera hot on his trail.

"STUPID COW! GET BACK HERE!"

"Gokudera-san, calm down!" Lambo yelled back at him. On accident, Lambo tripped on a wire that was attached to the bazooka and it landed right on top of Tsuna who got shot.

"Jyuudaime!" Was the last thing he heard as his surroundings were engulfed in a pink explosion.

Should I stop here? Nah, I would feel bad.

Tsuna woke up and looked around his surroundings. 'Where am I?' He thought.

He tried recalling back his memory. 'I was doing paperwork when Reborn came into the room and said that Shouichi-kun, Spanner and Giannini wanted to see me.. Then...' He looked up then a light lit up above his head.

"Ah.. Lambo came in and tripped which then cause the Ten-Year Bazooka to shoot me... But where am I?" Tsuna looked around some more then realized he was outside of the Vongola mansion. He sighed then stood up but then, noticed that his legs were rather short.

"Eh?" He gasped, why was his voice not as deep as it is supposed to be?

He looked at what he was wearing, it was the same thing he wore before (black blazer, orange dress shirt and black pants) except, it was much bigger.

"Don't tell me... I'm... BACK IN MY 14 YEAR OLD BODY?!"

"Oi! Who's there?"

Tsuna squeaked and looked around to see a pink-red haired man who looked so much like Gokudera walking towards him.

'E-ehh?! I-is that.. G?!' Shouldn't he go ten years into the future? Why was he in his ten years in the past body? Why is he seeing G? In flesh!

"Oi, kid. Why are you on Vongola property?" G glared at Tsuna. 'He looks a lot like Giotto.' He thought. But he knew better that Giotto didn't have children.. Or atleast said anything about having one.

"E-ehh... Ano.." Tsuna stuttered.

"Speak more clearly brat or else I will shoot you!" G threatened.

Tsuna backed up a bit then thought, 'What do I do?! Wait, why am I thinking like how I used to? HIEE not helping!'

"I-I'm-" There was another pink explosion and a figure had landed on top of Tsuna. Except this figure was surprisingly small.

"Tsuna-nii! Lambo-sama wants some more candy!" Tsuna's eyes widened.

"EEHH?! LAMBO?!" Tsuna stared at Lambo who is now back to his 5 year old body. And had somehow lost his mature and cool personality as well.

Lambo giggled then jumped on top of Tsuna, "I don't know why Tsuna-nii. But, Lambo-sama feels so young and wants to play! AHAHAHA!"

"Ugh Lambo! Stop it already and sit still!" Tsuna tried to calm down the now hyper active Lambo.

When Lambo finally calmed down, Lambo caught a better look at Tsuna and the person in front of him. "Tsuna-nii, why do you look so young? Why do I sound like a 5 year old? Where are we? And why does everything look much bigger than before?"

Tsuna sighed then said, "I don't know." Before he forgot, G cleared his throat and glared at the two.

"Answer my question brats. Why. Are. You. On. Vongola. Property?"

Lambo shivered and hid behind Tsuna. In his mind, he was wondering why the hell was he acting like a 5 year old? It seemed as if it was automatically what he was suppose to do. But he'll just go along with it for now.

"W-well.. I'm Sawada Tsunayoshi and this is Lambo.. We are umm..." What was he suppose to say? Say that 'We are from the future and had suddenly come back 400 years into past'. People would've thought they were crazy. So he ended it lamely with a "Lost."

G stared at them for awhile, figuring out if they were lying or not. As he looked into their eyes, no traces of lying or any bad he could see. But what was he suppose to do? He couldn't simply just leave them.

"Hmph. C'mon brats. I'll let Giotto deal with you." G walked away and Tsuna and Lambo could only follow behind.

Tsuna and Lambo were led around the mansion by G. They weren't surprised that inside the mansion looked the same. The only thing different about it was the smell that lingered in the area and a few antique vases that weren't there before.

G halted in front of a door that looked much like Tsuna's office door then knocked.

A muffled "Come in." was heard and G pushed the doors open and motioned for the two of them to get in.

In front of them, Tsuna was surprised he was seeing Giotto. Not as a spirit but in flesh! Lambo was also the same. He may not be as mature as he was but he was smart enough to know that he was in fact seeing the real Vongola Primo. In flesh.

Giotto stopped doing paperwork and looked up, surprised to see G with two children who looked to be around 5-14 years old.

"G, why did you bring children here?"

"They were on Vongola property, Giotto." G stated.

Giotto raised an eyebrow then looked towards the two. One of them had the same hairstyle as he did but he was a brunette. He wasn't sure but his Hyper Intuition told him they were no threat or anything. So Giotto did what he would usually do to greet children.

He smiled and said, "Hello, I'm Giotto. What's your name little ones? Would you like some cake?"

G and Tsuna gawked at Giotto with a 'are you serious?' look. G quickly fixed his compusure then yelled at Giotto, "What the hell are you thinking, Giotto?! They could be enemies! Spies! You don't offer cake to them all of a sudden!"

Giotto simply shrugged, "Why not? Afterall, I don't think they are a threat to us, right?" He looked over to Tsuna and he simply flinched and nodded his head meekly.

G huffed then made a mental note to lecture his boss about what happens if he gets too friendly with people. Giotto turned his attention back to Tsuna and as Tsuna was about to talk, another one came through the doors.

"Jyuudaime!" Tsuna's eyes widened and turned his attention to the figure at the door.

"Gokudera-kun!" Except this time, Gokudera looked much younger like his 15 year old self. Gokudera ran towards Tsuna like a puppy to its owner and then...

"Gomenasai, Jyuudaime! It was my fault that you got sent here!" He bowed down to him and hit his head against the ground multiple times. Pretty hard.

"N-no! It's okay, Gokudera-kun!" Tsuna tried stopping his right-hand man from hurting himself. Like before... And now.

"Ano, Gokudera-kun, how did you find me here?" Tsuna asked. Afterall, no one came in after him. It was either that he poofed in the mansion or outside where Tsuna was. If it was the latter then- "I fought down most of the guards outside then saw this office which reminded me of yours. Surprisingly, the mansion is still the same as the one in our era." Gokudera grinned.

'Gokudera-kun hasn't changed!' He mentally gawked at him.

Giotto and G were utterly confused and wondering how did a grey haired teenage boy get in the room. G found this suspicious but as he took a closer look at him. He reminded him a lot like himself and looks almost the same as him. Without the tattoo on his face and different hair color.

Giotto cleared his throat then said, "I'm sorry but, who are you?"

Tsuna spoke up since it became quite a natural thing for him to introduce themselves. "I'm Sawada Tsunayoshi, this is Lambo" He motioned to Lambo. "And this is my right-hand man, Gokudera Hayato." He sounded professional there. "And uhh it's okay. None of us wants-"

"Lambo-sama wants cake! Tsuna-nii! Lambo-sama wants cake!" Lambo piped up.

Tsuna sweatdropped and Gokudera growled at Lambo, "YOU STUPID COW! Do not trouble Jyuudaime further!"

Lambo looked over at Gokudera, suddenly feeling this urge to fight back like how he used to. And so he stuck out his tongue and said, "Ahoudera! Listen to Lambo-sama and get me some cake! Mwahahaha!"

A vein popped on his forehead and he started shaking Lambo. "You're no different from your old self stupid cow!"

"Gokudera-kun! Let go of Lambo!" Tsuna tried prying Gokudera of off Lambo.

Gokudera didn't listen to Tsuna as he continued shaking Lambo up and down.

Giotto and G could only sweatdropped. It seems as if now they were the background characters.

"What an odd bunch of kids." The two muttered.
