Adventures in Italia ~Primo Generation~

When an enemy of the Vongola Famiglia went to the time of Vongola Primo to wipe out the Famiglia Tsuna and his Guardians were sent back to stop him. They didn't expect to show up as little kids, let alone be taken in as the Primo generation's children. Tsuna decided fate really had it in for him.

Chapter One

"What exactly did you say?" Reborn cocked his Leon gun at Giannini, dark eyes narrowing dangerously.

Giannini swallowed hard and twiddled his thumbs, not wanting to have to repeat the horrible news.

"The Astarita Famiglia has managed to copy the Bovino's time travel research and from the readings we gathered, it appears they sent their top generals and strongest fighters into the past… Vongola Primo's time to be precise." Giannini explained, voice small as he felt the intense glare of Reborn and all of the Decimo's Guardians on him.

"I have a bad feeling about this." Tsuna rubbed his forehead; the young Don's Hyper Intuition flaring up so much it was giving him a headache.

"If they traveled that far back in time then it is likely they are going to try to destroy the Vongola before it grew in power." Hayato theorized, hand going to rest on his Buckle of the Storm out of habit.

"With their box weapons and advances in Dying Will Flames the Primo Generation won't stand a chance." Takeshi clutched his Necklace of the Rain, rubbing the metal with his thumb trying to soothe himself.

"That is exactly why you all are going back to stop the Astarita before they can get to the Primo Generation." Reborn let Leon turn back into his original form, to curl up on the brim of his fedora.

"Wait you want us, to go back in time and stop an army while avoiding being killed by the Primo Generation? Are you insane?" Tsuna gapped at Reborn with wide eyes.

"That's exactly what you are going to be doing Dame-Tsuna." Reborn's eyes glinted.

"Oh for the love of." Tsuna sighed, tipping his head backwards.

"Get working on it Giannini! You have until sunset!" Reborn turned to the inventor who nodded, body shaking.

"I'll send Shoichi, Spanner and Verde over to help you." Hayato pulled out his custom Vongola X cell phone to make a few calls.

"Good idea, you know they would be annoyed if they missed out on the chance to mess with time travel." Takeshi agreed before locking fingers with Chrome, dragging her over to Tsuna. Together the Rain and female Mist pulled their stressing out Sky out of the lab.

"You will get to fight many strong opponents, maybe even fight with the Primo Cloud." Reborn said loudly, to stop Hibari from exiting the room clearly not interested in this.

"Hn. I'll bite them all to death, then bite the carnivore to death." Hibari stated before he leapt out the window.

"That's a 'I'm in'." Lambo guessed, he was getting better versed in the art of Hibari speak.

"If my dear Nagi-Chan and Tsunayoshi-Kun are going then I will come along, just to insure that my future vessel will not be damaged." Mukuro conceded before he disappeared in a wave of his Mist flames.

"They are on their way, well as soon as they can get Verde out of his lab." Hayato snapped his phone shut, he liked the older style of flip phones because he secretly liked the fact he could hang up on people and he looks more dramatic when finishing his call.

"Come on Tako-head! We must prepare for this extreme time traveling adventure!" Ryohei latched onto Hayato's arm dragging the protesting Storm out of the lab while the small Lightning Guardian trailed after them, laughing at all the curses Hayato was letting out.

"You can calm down now Tsuna." Takeshi gently pressed Tsuna onto a love seat, rubbing his shoulders, feeding the stressing Sky some of his Rain flames smiling when he felt Tsuna relax under his hands.

"How can I calm down? You know how I feel about time travel and back to Primo's time! This is ridiculous!" Tsuna groaned, lifting up his arm for Chrome to curl into his side, knowing this calmed both of them.

"We know bossu, but if they get hurt…" Chrome said softly.

"I know, I know. I just wish this bullshit happened to someone else instead of it us, it's always us." Tsuna sank further into the couch as Takeshi increased his Rain flames.

"We know Tsuna, but we can handle this just like everything else that has been thrown our way. Besides won't it be cool to see the Primo Generation in action?" Takeshi asked, excitement in his voice.

"Yeah it would be interesting to see them all when Vongola started up before Secondo's reign began." Tsuna said, resting his cheek on the top of Chrome's head.

"Daemon Spade." Chrome whispered and Tsuna felt her shiver, Takeshi dropped one hand onto her shoulder to give her some of his flames while Tsuna laced their fingers together soothing her with his Sky flames.

"This Daemon won't be the same, if we go back before Elena is killed he will be different. No matter what Daemon it is, we will protect you if he can get past Mukuro that is." Tsuna promised, eyes glowing orange. Chrome smiled happily as she felt her Mist harmonizing with her Sky and her Rain.

"What are we doing here?" Hayato asked, crossing his arms over his chest as Ryohei started to shed his orange jogging jacket, stretching his arms out while Lambo perched on a nearby tree branch, both eyes open to watch his older brothers.

"We are going to extremely spar without our Vongola Gear." Ryohei declared.

"Without… Okay, fine let's do this." Hayato agreed as he stripped off his suit jacket and tugged off his tie.

"That's the extreme spirit!" Ryohei said cheerfully. Ryohei didn't waste anytime, he launched himself at Hayato with a strong right jab, Hayato ducked under the fist and brought his own fist down onto Ryohei's right thigh before the bomber rolled out of the way of Ryohei bringing his other leg up to kick at him, ignoring the pain coming from his hit thigh.

"Getting tired already old man?" Hayato teased the slightly older man, Ryohei just laughed loudly while Lambo sputtered from his place in the tree.

"Not even close." Ryohei bounced on the balls of his feet as the two circled each other, throwing testing punches and kicks every so often.

"Yare, yare this is getting boring." Lambo grumbled as he watched the Sun and Storm get locked into yet another wrestling match. He slid off his branch, thinking about how it was unfair that I-Pin had disappeared with Fon for a training week while Kyoko and Haru had gone into Milan with Bianchi to meet up with Lussuria for fashion week. Lambo wandered around the gardens, fiddling with the green Vongola storage box that held his Thunder Helm of Lightning.

"Where are you going little one?" Mukuro asked as he appeared in a wave of Mist flames, Lambo might have startled in the past but now he was used to Mukuro popping up at random times from the middle of the night to the middle of an exam just to see how Lambo would react. It amuses him to no end and it may be pay back for all the times Lambo calls him Mukuro-Nii. Lambo called him that knowing full well that Mukuro would appear at random times.

"Bakadera and Ryohei-Nii are wrestling and I didn't want to get dragged into that." Lambo raised his hands, his green-gemmed Vongola ring flashing in the dying sunlight.

"Those two are rather loud." Mukuro agreed as he fell into step with their youngest, his long navy hair swaying as he walked. He had decided to grow his hair into the style his future self had when they had all traveled to the parallel future.

"Why don't we mess with them a bit?" Mukuro let out a little laugh as Lambo brightened up at the offer.

"What are we going to do Mukuro-Nii?" Lambo asked, excitement evident in his voice and face.

"How about zero gravity?" Mukuro ruffled the Lightning's hair looking at his little brother with a fond look.

"Let's try to see them fight like that!" Lambo laughed before gently grabbing Mukuro's gloved hand making sure Mukuro didn't pull away as he was still hesitant about contact after everything he had been through. Mukuro gripped Lambo's hand in return and allowed the teen to tow him back towards where the Sun and Storm were fighting.

Mukuro hid their presences from the two guardians and waved his trident at the two men. Lambo covered his mouth with his free hand to muffle his laughter as Hayato and Ryohei let out unmanly yelps as they floated into the air, turning head over heels and arms waving around.

"Extreme!" Ryohei cried out, a smile appearing on his face as he started to pretend to swim in the air, he circled around Hayato.

"Mukuro!" Hayato called out, hovering in the air with his legs and arms crossed a tick appearing on his head.

"This is great!" Lambo told Mukuro happily as Ryohei grabbed onto Hayato and swung him around causing the Storm to curse the Sun out.

"It is rather amusing isn't it?" Mukuro let his lips twitch upwards.

"Are you going to be okay with going into the past… You know with Daemon Spade and everything?" Lambo asked, tightening his fingers on Mukuro's hand. Lambo knew that Daemon Spade still was a sore place for both Mukuro and Chrome.

"I am more powerful than him, I will not let him harm anyone." Mukuro stated firmly.

"I know you won't Mukuro-Nii." Lambo smiled up at the Mist. Mukuro blinked at the teenager still clutching his hand before he gave a nod of his head and twirled his trident and Lambo chuckled as the Storm and Sun started to spin around in the air.

"MUKURO!" Hayato cried out as his silver hair fell over his eyes.

"Kufufufufu, does the little dog want to go down?" Mukuro allowed him and Lambo to appear.

"I should have known you were part of this Ahoshi!" Hayato's eyebrow twitched at seeing the Bovino.

"Oya, oya don't be like that doggie, this was my idea." Mukuro smirked.

"Whatever, it's time anyways… So let us down!" Hayato announced when he scanned a text message from Shoichi.

"Extreme time travel adventure!" Ryohei punched the air as Mukuro let them drop onto the ground, Lambo giggling at the curses Hayato let out when he landed heavily on his butt and Ryohei crashing down on top of the Storm.

"Let us go little one." Mukuro tugged Lambo who was still gripping his hand towards Giannini's lab.

~~/~~

"So whose ready for some time travel?" Takeshi rubbed his hands together when the Decimo Generation all were gathered in the lab while Shoichi was rubbing his stomach while Spanner was tweaking something with a wrench while Giannini was sweating bullets. Verde was looking calm and collected, if not for the manic glint in his eyes the Vongola would have thought he was level headed.

The gathered group had changed out of their formal wear and where now wearing their usual comfortable clothes and their Vongola Gear as per usual.

"Not me." Tsuna muttered with Chrome latched onto his arm, partly to stop herself from running away and partly to stopping Tsuna from running away.

"Man up Dame-Tsuna." Reborn shot at the Sky who leaned sideways to avoid the bullet out of habit.

"Can't the Primo Generation take care of themselves?" Tsuna rubbed his head with his free hand.

"We went over this, now get on the teleporter pad." Reborn shot at their feet and the group scurried onto the mentioned pad, well all of them but Mukuro and Hibari (who had silently snuck into the lab), as they were too 'regal' to scurry.

"With our calculations you should end up right where the Astarita Famiglia are gathered. When you defeat them, focus your flames into your Vongola Gear and harmonize with Tsuna's flames and it will bring you and anything your touching back here." Verde explained as the gathered flame users shifted on their feet.

"And if anything goes wrong?" Hayato asked, always thinking about contingency plans.

"Same deal, focus on your gear, harmonize and it will bring you back." Giannini answered the question.

"Get going, we can't risk the Astarita Famiglia getting to Primo before you get to them." Reborn snapped at the gathered scientists.

"Get ready everyone." Spanner typed on numerous keyboards.

"Good luck!" Shoichi waved weakly, his stomach acting up.

"Don't die." Reborn smirked as Verde threw a large switch and the pad filled with a bright rainbow colored light. When the light faded the Decimo Generation was gone, but lying in a pile was their collective Vongola Gear and custom made rings that opened their Vongola boxes.

"Oh no." Shoichi gasped as he doubled over in his chair.

"Why didn't their gear go with them?" Reborn pointed his Leon gun at Verde who was scanning information.

"It should have by all counts." Verde denied.

"Find a way to get them their gear, without it they are dead in the water against the Astarita Famiglia with no way back here. Fuck I hate time travel." Reborn rubbed his forehead.

"More bad news." Spanner spoke up from where he was eyeing the beeping radar.

"Now what?" Reborn walked over to the radar, leaning over Spanner's chair.

To his credit Spanner didn't even flinch. "It seems the remaining members of the Astarita Famiglia are making their move. They must have a mole in the Vongola and now that Tsunayoshi and the others are gone they are making their move."

"To take out Vongola in the past and present, a two-pronged battle strategy. This had been years in the making. Verde I'm going to make some calls, find me that mole and get my Dame student and his Guardians their Gear!" Reborn shouted over his shoulder as he stalked out of the lab, bloodlust rolling off of him in waves.
