Hi everyone. This is my first story and I'm only 14 so don't be harsh, yeah? :p Please do read! Thank you :D

Summary : The story revolves around Sawada Tsunayoshi and his 6 Guardians of the Sky. A new Famiglia, the Pentiti Famiglia, has appeared and are dead set on finishing the Vongola off. Question is, why? Who are they? What do they want exactly? *Set after the Rainbow representative war

*Starts with flashbacks about the past.

Disclaimer : I obviously do not own Katekyo Hitman Reborn though I wish I did. I mean, who wouldn't? :) I praise the genius who did.

Chapter 1: The Past

Tsunayoshi Sawada, the soon-to-be 10th Vongola head, was barely awake.

He was sat on a straight-backed leather chair overlooking a balcony. He was in his library; an adjoining room to his bedroom in the Vongola mansion.

Tsuna, was in short, reminiscing.

About when Reborn had first come to him; When he met his guardians one by one; When they went on their first adventure together; When they went into the future and fought the Millefiore Famiglia and Byakuran; The inheritance trials; Of the rivalry and the friendship with the Simon Famiglia; When the rainbow representatives war was waged... and won.

The joy he felt when Reborn came out of the negotiating room with the rest of the Arcobalenos. They'd decided Colonello was to be freed from his curse, along with Lal.

So much has passed and yet, he knew so much was still yet to come.

He pinched the the bridge between his eyes, wondering. Was he ready for all this? For the pain, the tragedy, the drama, the adventures, the responsibility for the lives of so many?

So deep in thought was he that he failed to notice the presence of another in the room till a voice said, 'Da-me Tsuna.' a hard slap was placed upon his cheek. 'Stop worrying. You'll be fine.' accompanied with a wry smile.

'Reborn!'

By then Reborn had jumped onto Tsuna's lap.

'What are you worrying for, idiot?'

'... I-I don't know if I'm ready. For all this.' Tsuna gestured a wide arc.

Tsuna expected Reborn to say something comforting, reassuring. 'Have you ever been ready for anything that's been thrown your way?'

Or not.

Thinking back again, he realised, he never was. And yet, he managed to survive, to succeed, to get through, each time.

Was it luck? No. It was because of the support he had. His guardians - No, his friends, Reborn, his family.

He smiled. Instantly cheered up.

Reborn stared at Tsuna. God, it was sooo easy to piece this guy together.

'Jyuudaime.'

They both whipped their head to the speaker.

It was Gokudera and the rest of the Guardians. Why were they all here together?

'Yes, Gokudera-san?'

'U-um. We h-have s-s-something to r-report.' stuttered Gokudera which wasn't like him at all. 'R-recently ... -'

Shut up, herbivore. You irritate me. You're useless.' interrupted an obviously irritated Hibari.

Hibari turned to face Tsuna. 'Omnivore, remember the men you put under them?' he asked, pointing to the rest of the guardians.

Tsuna had to think back a bit. A while ago, more and more trouble kept popping up. Be it new Famiglias or rogue mafia or assassinations.

To get it all under control, he had put squads of men under the guardians so as to help complete missions faster.

All except Hibari who preferred to do missions alone and Lambo, who was too young. The idea had been going well.

At least until now...

Unsure, Tsuna replied. 'Yes. What about it?'

'Recently each squad was sent to Paris, China, Malaysia, Italy on an intercepting mission. It was a success of a sort.' Hibari looked sharply at the guardians; Waiting for someone else to continue. He'd done way too much talking already for his liking.

Unexpectedly, a smirking Mukuro did. 'Vongola, when they came back, they each came back with a similar letter. There's one on your desk right now.'

Tsuna was surprised to see one on his desk so fast. The unopened letter was stamped with an insignia in red wax. It was diamond shaped, it's inside was of four arrows pointing upwards to a crown. Tsuna tore open the letter and read it;

Greetings, Vongola Decimo; Vongola Guardians.

The infamous Vongola Famiglia... What did you have to do to get so infamous? How many did you have to kill? Did you step on people to claw your way up to the upper echelons of the Mafia world? Oh, so curious.

But, we will have time for that in the future.

Today, our only intention is simply to introduce ourselves, the Pentiti Famiglia. It pains us to say that we are relatively unknown despite the fact that we've been around since forever. Longer than even you, Vongola.

Fairly recently, the old head died and a new one took his place.

That is I. And I intend to change everything.

A warning, Vongola Famiglia. Your reign may not last as long as expected.

You will be hearing from us again,

Pentiti Famiglia.

With that the letter ended.

16 year old Tsuna was quite literally shaking in his pants. 'W-what? B-but... T-this is...' stuttered Tsuna. 'Eee-ahhhhh!' Tsuna quickly covered his head with his arms as Reborn's leg came down on him; hard.

'Da-me Tsuna. We just talked about this.' Reborn shook his head. 'The rest of you, what are you expecting to Tsuna to do? He's obviously useless. You'd be better off settling these matters amongst yourselves.'

'Reborn-san!' Gokudera protested.

Tsuna kept quiet.

Unexpectedly, it was Hibari who said something. '... Infant.' he said, addressing Reborn. 'I want to know what the omnivore has to say.'

'I agree. Young Vongola may still be naive and inexperienced but, he is still our... Vongola.' Mukuro said wryly with a hint of distaste.

'Yeah kid. Give Tsuna chance!' Yamamoto said with a smile.

'Tsuna's opinion matters extremely to me!' exclaimed Ryohei exuberantly.

Lambo was leisurely digging his nose, oblivious to everything that was happening. 'Lambo no care.'

Gokudera regarded Lambo with undisguised disgust. 'Stupid cow.' he muttered. 'Reborn. I want to hear what the Jyuudaime has to say!'

Reborn pulled his fedora down to hide a secretive smile. Everything went as it was supposed to. As it always did.

Now, what was that letter about? The Pentiti Famiglia. Reborn would make sure to research about them later.

To say Tsuna was touched would be an understatement.

'Thank you, everyone.' Before speaking up, 'I think we should leave it be. It may be empty threats after all.' He spoke with an authoritative voice. It wasn't the first time their Famiglia had been threatened or warned nor will it be their last.

All sorts of funny and silly letters passed through their mailbox. Some even threatened Tsuna's safety. Mysteriously, those that did disappeared quietly after that - Tsuna suspected it had something to do with Gokudera and his squad - while some, were as he said; empty threats.

There were some disagreements. Sure, they had received similar letters but never any such as this. It was neither a threat nor a prank. It was a warning. Warning for what? Who were they?

Tsuna was puzzled.

In the end, it was agreed that it was best, to leave the matter to Vongola Nono and Guardians.

They'd enlisted Hibari, Mukuro and Chrome to help their investigations about the unknown Pentiti Famiglia.

It was to no avail.

The matter was dropped after a few months.

The reason was simple, the 'Pentiti Famiglia' did not exist.

So guys! Whatcha think? Was it... good? Is it boring?:\

Oh and I'll upload the 2nd chapter mega fast!
