Chapter 1

It was just like any other day for the young Vongola Decimo; Gokudera threatening to blow everyone up with his dynamite while Uri shredded his face; Yamamoto laughing while observing Uri in maiming her master; Ryohei shouting that Gokudera was an octopus head while encouraging the fight; Lambo demanding candy from random strangers as they come over to see what the ruckus was about; Hibari and Mukuro having a sparring session with Chrome admiring the other Mist Guardians' illusionary technique; and Enma and Tsuna being tortur – ahem – tutored by Reborn for not living up to the expectations set by the First Generations.

"Get up, Dame-Tsuna, Loser-Enma; we still have fifty laps around Namimori and then you get to fight Hibari and Ryohei for three hours," said the World's Greatest Hitman, cocking Leon in his hand and pointing it at his students. Even though it had been three years since the Representative Battle with Checkerface, the archobolano still grew up at the rate of normal children, making Reborn in an eight year old body.

"T-th-three hour fight!?" yelled Tsuna in horror.

"F-fifty laps around all of Namimori?" questioned Enma in equal disbelief.

"Th-there's no way that's possible, Reborn!"

"You two got a problem with that?" the baby inquired, a glint to his eyes, and both Tenth Generation bosses gulped in fear, running away as fast as they could, forgoing their usual clumsiness for distance.

Three and a half hours later, Tsuna and Enma were sporting a fresh array of bruises and scrapes; Tsuna had a swollen cheek and Enma two black eyes.

They continued shuffling in their own misery, cursing a certain fedora wearing archobolano under their breath until said baby appeared in front of them.

"Oi, Tsuna; tomorrow there's a party at Vongola Mansion and your prescience as the next boss is required. Loser-Enma and Shimon Famiglia are coming as well, so go tell your Guardians," said Reborn as he promptly kicked Tsuna in the head, causing him to crash into Enma, which sent them both to the ground. "Better hurry; the flight leaves in three hours, but I want your Guardians assembled in twenty minutes."

"Uggh…. I'll see you then, Enma-kun," said Tsuna as both boys rushed off to find their respective Families.

"See ya, Tsuna-kun,"

After bribing Lambo with candy, calling Gokudera and Yamamoto, nearly getting bitten to death my Hibari, jogging (more like sprinting long distances) with Onii-san, and finding Chrome and Mukuro at Kukoyo Land, Tsuna somehow managed to get all his friends to the airport with exactly two minutes to spare.

"Kufufufu….Sawada Tsunayoshi, you better have a good reason for dragging us all to Italy," Mukuro said, brandishing his trident and unnerving everyone but Chrome and Hibari with his red and blue eyes.

"M-Mukuro-san, e-eto, i-it was Reborn's orders and Enma and Shimon are coming too…" Tsuna replied weakly.

"Oi, Pineapple-head, quit intimidating Juudiamie or I'll blow you to bits!" shouted Gokudera.

"Ma, ma, Gokudera; Mukuro was just asking, no need to get so worked up,"

"EXTREMLY, TAKO-HEAD! I WAS WONDERING THE SAME THING MYSELF!"

"SHUT UP BASEBALL-FREAK! TURF-TOP!"

"STUPIDERA! LAMBO-SAMA WANTS CANDY! GIMME IT!"

"WHAT WAS THAT, TAKO-HEAD!?"

"SHUT UP SHUT UP SHUT UP!"

"Ma, ma,"

"Herbivores, shut up or I'll bite you all to death," snapped Hibari, brandishing a tonfa before yawning and heading onto the waiting private plane.

Tsuna sweatdropped.

"B-Boss," a timid voice said. Tsuna looked over and saw Chrome pointing down the hall. "Shimon Family has arrived,"

At the news, everyone stopped and looked down the hall before starting new arguments with the Shimon. It relaxed Tsuna to see how seamlessly they melded together; Koyo and Ryohei having a spirited yelling match, Adelheid blushing and kicking Julie, Lambo climbing over Rauji, Yamamoto and Karou talking about baseball, and Gokudera observing Shitt P. meditate.

"Five seconds left," Enma sighed in relief. "Hey, Tsuna-kun,"

"Hi again Enma-kun, Shimon Family minna-san,"

"Now that we're all here," said Reborn as he dropped from the ceiling "We should all get on the plane,"

"W-wait a minute, Reborn; none of us packed anything to bring with us,"

"Shut up, Dame-Tsuna," Reborn said as he turned Leon into a hammer and hit him with it. "Nono already has everything prepared, so be an obedient lacky and get on the plane,"

"Haaaaaahhhhhhhhhhh!" yelled Tsuna as he ran into the plane, his family and Shimon following.

During the last three years, everyone had grown. Gokudera was almost a full head taller with more muscle definition but still slender.

Yamamoto and Ryohei as well had grown about a head taller, with Onii-san have the most muscle of the Tenth Generation Vongola Guardians.

Lambo was still a brat, but he had learned a small bit of manners that always disappeared with every argument.

Chrome was a little less shy with the Family and Shimon, but not with strangers. Mukuro, while being grateful to Decimo for getting him released from Vendicare, was still trying to possess Tsuna, but not as much as he used to.

Hibari was much more inclined to put up with the noise the group made after Tsuna gave him a pair of noise cancelling headphones.

The biggest change of all was Tsuna. He had shot up during puberty, him standing on equal height with Gokudera, his voice had deepened, getting rid of his old girly shriek (probably another reason Hibari stayed around longer) he had grown into his wild mess of hair and it now framed his face better, and his eyes were no longer as wide, but a clear honey and tinged orange from being in Hyper Mode so many times. He quite resembled the First Sky Boss.

But inside he was still the old and loveable Dame-Tsuna.

"When will Reborn stop trying to kill me?" sighed Tsuna, sinking into his chair as Enma, Gokudera and Yamamoto took the seats next to him. Hibari had already taken the sofa, his headphones on and Hibird on his chest.

"Juudiamie, is there anything wrong?" asked a worried Gokudera.

"N-no, but I do worry that Reborn's training methods might kill me soon…"

"Hahaha, I don't think the kid would do that, Tsuna,"

"Shut up, Baseball-freak,"

"Ma, Gokudera. By the way, does anyone know how long the flight will take?"

"Eto, I think about seven hours because Spanner-san and Shoichi-kun modified the engines." replied Enma.

"Why would you know that?"

"E-errm….because the last time I had to go to Italy, I saw them working on this plane and asked them what they were doing; they said they were upgrading it. Since I didn't see Gannini-san around, I figured it would still be safe to use…"

"Humf. So long as that failed mechanic hasn't gotten hold of this piece of junk, then the happier I'll be," muttered Gokudera.

"Kufufufu…. Seven hours is too long to be on a plane with you people; Chrome, I'll see you there…." Said Mukuro as he faded into mist.

"Yes, Mukuro-sama."

~Seven Long Hours Later~

"EXTREME! We are EXTREMELY in EXTREME Italy!" shouted Ryohei as everyone stepped off the plane, making other fliers wince at the sheer volume.

"Well now that we're all in Italy, I expect you all to speak Italian. A good Mafia boss should be able to do that," said Reborn as he jumped down from Tsuna's shoulder.

"OK," said Onii-san before scrunching up his and shouting in Italian what he had said earlier.

It was a good thing Reborn had been the demon-tutor he was, or Tsuna and Ryohei would never have learned the second language. As it was, Tsuna still had nightmares and woke screaming in the language…

"Hehehehe, Lambo-san is gonna eat a WHOLE LOT at this party, ne Tsuna~!" sang the little cow.

"Eh? O-oh yeah, sure Lambo,"

After the ten-minute car ride to Vongola Mansion, with Hibari on the roof, they were ushered in and greeted by Nono.

"Ah, little Tsuna, you've gotten so big; looking just like Primo,"

"Hahaha… Good after noon, Grandfather,"

Timoteo smiled, and nodded at his personal hitman.

After getting settled into their rooms, Tsuna changed out of his casual cloths and into a black suit with no tie before proceeding to the meeting room, where he would find his Guardians and Shimon.

Hibari and Adelheid had already begun a sparring session, with Mukuro (who seemed to have reappeared) throwing taunts and illusions at the skylark. Koyo and Ryohei where screaming who was the bigger idiot, Lambo and Yamamoto were laughing, and Gokudera was running away from Shitt P.

Everyone was in Formal wear.

A loud *thud* alerted Tsuna to Enma's presence next to him, as the redhead face planted the floor.

"Enma-kun, are you hurt?" asked Tsuna, rushing to help his friend.

"H-hai, Tsuna-kun,"

~Watching Through A One-Way Mirror~

"Are you sure they should be the ones to be sent on this mission?" bit out Nono's storm guardian, Coyote Nought, watching the fool hardy chaos the two Families created just by being in the same room.

"And wait…weren't they trying to kill each other last time they were together? What happened?" asked the mist guardian, Bouche Croquant.

"Ara, Bouche, that was three years ago; they made up, remember?" said the ever optimistic rain, Schnitten Brabanters.

The reply was a non-comitial grunt.

"So, Nono; have you decided?" asked Reborn, also looking out the mirror. None of the Tenth Generation found it odd that there was a floor to ceiling mirror in a meeting room, and at this moment, Reborn was not tempted to train them for their lack of observational skill.

Nono sighed. If he and his Guardians were any younger, they would have done such an important mission themselves, but alas, Vongola was truly no longer in the Ninth Generation.

"I am afraid we have no choice but to send them,"

All in the room stiffened at these words, but Timoteo was not done yet. "I meant what I said about him looking like Primo though; in fact, they are all the spitting image of their predecessors. If they are to do this mission, they will need a disguise…"

Just then, Lambo walked up to the mirror and started making funny faces. Everyone watched the cow in contemplation, trying to see how they could help the Tenths stay moderately safe.

The Sun guardian, Brow Nie Jr., snapped his fingers in assertiveness. "That's the answer; who would be suspicious of a group of brats with no parents to watch over them in that time? After all, it was a fairly common occurrence; even they were subject to it…"

Everyone contemplated his words, watching as the two Families finally grew suspicious of the oversized mirror the Lightning Guardian was making faces at.

"If that's the best idea we can come up with…" resigned the Ninth.

"Hm," said Reborn as he kicked open the mirror like a door, making Shimon and Vongola alike scramble to the other side of the room, away from the 'Hunted Mirror!' as the young Mafia Don's and Lambo referred to it.
