Summary: Coming back from the future, they've changed. Never can they be careless for they were taught a lesson for which they will learn and so starts their journey in an attempt to change it all.

I know, I know… I haven't updated my other fics and here comes a new one… but-but this is one plot bunny that won't leave me alone! I'm So So So Sorry!

Important!

Since I noticed in the anime/manga I've watched/read that time flowed as it really was in the time Reborn was shot with the Ten Year Bazooka and when Tsuna went to the future as in a day had passed for Reborn as well in the future, so I'm going to base the flow of time of my story on that so let's say that Tsuna and the others stayed 2 months in the future, they also went missing 2 months in the past. Since I don't actually know how long they were in the future, so I say they stayed there for 2 months, capiche?

Warning: Most of them will be a little bit OOC!

Prologue

2 months! It had been almost two whole months since Reborn first to have disappeared then Tsuna and the others while it had been a month and a week and half since Hibari Kyouya and Sasagawa Ryohei disappeared as well.

Almost 2 months ago… (Time progresses from the first few days of their trip to the future since I might not be able to keep reminding everyone of the passage of time)

Bianchi feared something might've happened that she was not aware of explained to Nana their association to the Mafia, not actually breaking Omerta since she was already deeply buried into it by being the wife of the External Advisor of Vongola Nono and the mother of the heir of the Vongola Mafia Family.

Nana took it in stride as usual but started worrying when a nice young man kindly asked ("Onna, where are the herbivores?") the whereabouts of her son and his friends. The young man introduced himself as Hibari Kyouya the head of the Namimori Disciplinary Committee. Remembering what Bianchi, who at that time left to find the one's missing ("Nana, I'll be leaving for a while to find my beloved Reborn and the others.") told her, she recognized the man as Tsuna's Cloud Guardian. Honestly telling Hibari-san that her son and friends had gone missing ("Oh? So the akambo is missing as well?"). He kindly asked her to show him her son's room ("Onna show me the weak herbivores' room."). Nana left him there hoping he could find a clue to the mystery of her son's "Disappearing Act" as well as his friends. But when she returned to Tsuna's room Hibari-san was gone as well and hasn't been seen for the proceeding days.

Kusakabe Tetsuya knowing that Kyou-san (1) was last seen at the Sawada Household went their immediately and asked if they'd seen Kyou-san. When he got there Nana-san and Bianchi-san were talking to each other worry etched into their voices. Kusakabe asked them of what they knew. Then he started worrying as well. He asked if there was anyone they could ask for help for in the Mafia. He knew of it since Dino Cavallone had talked to him about it and was silenced by Omerta. Since that Kyou-san was already willingly delving into the world of Mafia he had to know since there was no doubt that Kusakabe would follow Kyou-san to the very ends of the worlds.

Bianchi almost immediately contacted Dino Cavallone but not before the families of the other missing came crashing through the house. By then it had been 3 weeks since Reborn first disappeared, Sasagawa Ryohei who was with the frantic parents of Miura Haru, Yamamoto's frantic father and his own parents, had also disappeared. Ryohei had basic knowledge of what had already occurred since he was a guardian before anything else. When Yamamoto's father and Haru's parents came barging in into Ryohei's home, Ryohei was almost cleaved in half by the frantic sushi chef. He explained the situation from what he gleaned from Bianchi with out the usual energy he omitted. Unfortunately, he had also disappeared in front of them, no less. The families waited a few more days before they rushed to the Sawada household to get more information about their missing children. Fuuta was the one that greeted them upon entering quickly directing them to the dinning room where Tetsuya, Biachi and Nana was talking. They were also informed of their association to the mafia since it involved them one way or the other. They were quite understanding of the situation and believed them. They asked if there was any way to contact the allies in the mafia to get help. So Bianchi rushed to the Cavallone base set up in Japan since Dino frequented Japan a whole lot often.

Once Dino heard of the disappearances, he ordered his whole Famiglia to using all their resources to find his little brother and his Famiglia. He then went and visited Kokuyo land in hoping of speaking to Chrome, more specifically Mukuro. What he found there scared him, as explained by Ken and Chikusa ("The be-damned bitch has gone missing 2 weeks ago."). Dino truly started worrying big time (My poor cute little brother, my little Tsuna. Don't worry, big brother Dino will save you!) Dino then went to the one other person he answers to aside form his ex-tutor, Vongola Nono.

Dino hastily returned to his office that had a two way video link for private communication between bosses. He was one of the few who had direct link to the Vongola Nono's main office in comparison to their other allies.

Timoteo was minding his own business nursing a glass of scotch whilst staring out his window just finishing his mountain of paperwork for the day. He was somewhat worried for Reborn hadn't sent any reports or even a single letter for the past three weeks. He left the Arcobaleno alone in handling the training of his heir as he trusts the hitman. But it slightly scares him there hadn't been any reports for the past 3 weeks. As he was about to sit down back onto his office chair, the flat screen of which he used for his private conversations with trusted allied bosses came to life. As it came to life, the doors to his office burst open and in came Sawada Iemitsu with his CEDEF members and Xanxus with his Varia officers. (A/N: I will be assuming that the CEDEF don't know as opposed to the manga/anime, since I've found evidences of Iemitsu having some sort of contact with the future. Ie: the horn of the future 25 year old Lambo that he used in the Vongola Ring Battle, receiving an old horn of his that was actually the current Lambo's, at that time, that he lost as he grew up. And since that, I think Basil was helped by the future CEDEF when he arrived in the future in Spain.) As Timoteo was about to shoo away the two independent sub-branches of his Organization., Dino, as it turned out was the one that contacted the 9th frantically shouted through the communication line.

"Timoteo-san! Tsuna, Reborn and his Famiglia have gone missing!"

The whole room stilled at the voice of the Cavallone Family boss.

"What?" chimed Timoteo and Iemitsu.

"VOOOOOIIIIIII! Cavallone, the hell do you mean 'missing'?" Superbi Squalo barked.

"Missing as in we-can't-find-them-and-they-might-be-already-dead missing. Damn it! Where the hell are they?"

"Since when has Tsuna been missing, Cavallone no Jyuudaime?" Oregano asked the Tenth Cavallone boss.

You can skip this.

(A/N: You know, I think Akira-sensei was hungry whenever he made the manga, really or naming characters and creating their "quirks". Given Examples: Oregano, the female CEDEF member shown in the Varia arc that is not Lal Mirch, a type of herb. Basil, another type of herb, Tsuna, basically saying Tuna (the fish) in English turned Japanese. Tako-head (Octopus head) the nickname of Ryohei for Gokudera, Squalo meaning shark basically and shark is also eaten you know..., Miura Haru, somewhere in her name there's the katakana of ox. Tori-atama Bird head might translate to (maybe) chicken-head as some of what I can remember, Levi-A-Than can be read as leviathan, an ancient mystical sea creature (basically as what I think as sea food.) Then of course let's not forget Pineapple head Rokudo Mukuro, then there's the great "chefs" as relatives… I think. Then there's the fact whenever I hear or read names of some of the characters I seem to think of food as well. (ie. Belphegor, Lussuria, Collonello, Lal Mirch.) Then there's Byakuran's fixation for marshmallows, Gianini rhymes with Panini (French bread), Shouichi's stomach aching whenever he's nervous (when DOES the stomach ache or grumble? Isn't it most of the time whenever someone's hungry?), Lambo's fixation of candy (ok forgivable, he's a kid.), I-pin's source of "power" the very stinky meat bun, Bianchi's unique fighting style, Belphegor licking his lips whenever he's "hungry" for blood or the death of opponents (this can be ignored of course... since almost all "bad guys" do this.), Marmon "eating" his opponents even if it was an illusion...)

Thank you for reading if you did. This is patented rant/trivia (in my opinion…) someone might actually find this in mangafox . com 'cause I posted it in a forum thread there.

"Reborn had first gone missing 3 weeks ago then the next day was Tsuna and from information his Storm guardian after a few minutes then his two girl friends, a child named I-pin, his Rain and Thunder Guardians the next day. A week later as I've found out was the Chrome Dokuro his female Mist Guardian and half a week later was the Cloud Guardian and the Sun Guardian upon investigation also disappeared a few hours after." Dino explained a little more calmed down.

"This is troubling, and you're sure this isn't one of Reborn's training trips?" Timoteo asked.

"Yes, it's because even Bianchi, the Poison Scorpion didn't know of anything of the sort."

"Oi, Cavallone trash when were you informed of this?" Suprisingly Xanxus hadn't started laughing minutes ago and was looking quite calm at the moment. 'Probably he's already forming a plan to take over' thought Dino. He cares for Tsuna, true. But he'd rather see Tsuna dead than actually delving into the Mafia.

"I was just informed as of today. I quickly pulled up every resource we had into finding them…" relating to them the events that had occurred, Dino was thinking while he talked that some kind of conspiracy had gone on after telling them of the information that they had gathered.

"Father, I'll lead the search for your heir." Xanxus calmly stated.

His statement shocked most of them into silence and was broken by Squalo.

"WHAAAAT! Are you out of your mind, boss! Damn it! You have the chance to be the Decimo now! If the brat is dead and so are his guardians you're the only heir available left even if your not Vongola blood. Unless of course the Outside Adviser plans on another child." Squalo stated quite loudly.

"Kyuudaime, if you will allow me I have some other concerns to add to this troubling news." Iemitsu calmly stated but the shock of his son's disappearance still clear on his face.

"Wait for a moment then, Xanxus, Squalo. What is it my old friend?" Timoteo asked suddenly looking older than he was.

"If my calculations are right Basil had disappeared 2 days after Hibari Kyouya and Sasagawa Ryohei." He answered the Ninth. (A/N: From what that I can understand in the manga was Basil only knew what he knew because he had a handy-dandy (note)book (Damn, sorry for that I really liked Blue's Clues with Steve not the other guy and I STILL watch re-runs.) that he could count on what was happening at that time.)

"This is troubling, very troubling indeed. Weren't you training him to be the Outside Advisor to Tsuna-kun?" Timoteo asked.

"Hai."

"Wait, if all the guardians which are outside and free then…" Timoteo trailed off and suddenly picked up the phone and called Vindiche.

"This is Vongola Nono I'm inquiring about… yes… b-but how? (Long silence) I… see. I hope you'll keep to that." Timoteo put down the phone.

"It seems that even Rokudo Mukuro has gone missing as well in his cell. The Vindiche are willing to let him go even after he returns. Seems like they have a member there that had been one of the subjects of the Estraneo family that can predict and see the unknown. The girl had said to them that it's better to leave him be and that he'll come back changed or something along those lines. The Vindiche seemed to know the disappearances of Tsuna and his family as well." The Ninth said as he stood up and walked to his giant window letting him see the large grounds of which his HQ is. (A/N: I'm not sure if he did come 'cause I remember Shuichi saying that "He'll be coming soon.")

"Then, what shall we do?" Xanxus said still continuing his strange behavior.

"Go to Japan and stay there to reassure Tsuna and his guardians' blood family and observe from there. I have a feeling that they'll be returning there and that we need to be there once they do return." Timoteo had said his piece with his eyes slightly glowing orange.

'His Vongola blood must be kicking in.' Iemitsu quietly thought to himself.

"Then, in your permission I would like to accompany you." Xanxus spoke up.

"Permission granted, my son. But before we all go off packing what changed, Xanxus, for you to become this complacent and submissive? There has to be a reason." Timoteo asked his wayward adoptive son.

"That is my secret to tell, father." Xanxus looked up to his fathers eyes in that for the first time that a mischievous gleam sparkled in his eyes. Timoteo was surprised. Xanxus had never shown any emotion anything outside of wrath and rage. 'He has never called me father before. He's changed and it's being good on him.' Timoteo thought smiling gently at the changes that occurred in his son.

"Alright then, will your officers be coming with then?" Timoteo asked.

"Hell yes we will! The boss has gone nutters! We're going to be there and make sure comes back the way he was!" Squalo semi-shouted.

"Shi-shi-shi… This will be interesting…" Belphegor mumbled to himself.

They quickly packed up for a long stay in Japan; Iemitsu provided the housing in one of the hidden Vongola bases set up in Japan. Though base was an understatement, it looked more like a castle from outside. One of the still private Japanese traditional castles left that was actually found in Namimori. Nana and the family of the missing, only Kusakabe Tetsuya for Hibari, the Kokuyo gang and Dino Cavallone with his trusted Romario were invited to stay as well. They took up the hospitality presented to them. Everyday breakfast, lunch and dinner was a feast that could pass for a double five star restaurant with a professional sushi chef and Nana working the kitchens.

But as days passed they became more agitated, nervous and anxious. The Varia gang kept their "training" under the castle where a specialized training room was put in to prevent mass destruction in case anyone of their caliber was to train. The Ninth and Dino joined them occasionally showing them why they were the leaders of the strongest Mafia Families existing in the whole world. And so did the CEDEF once in a while spar with them. "To keep them on their toes" They said.

By that time two months had passed since the first disappearance and was quickly approaching the 2nd month of disappearance of the last one who'd gone missing and still they had no indication of Tsuna and his family showing up. That is until Gianini, resident clumsy inventor spotted something in his radar, one that observed the time-space continuum that he invented ever since he had first "upgraded" the 10 Year Bazooka.

"Kyuudaime-sama!" Gianini ran towards the temporary office of the Ninth startling most of the occupants along the way. Curious they followed the crazy inventor to the office of the Ninth.

The Ninth gazed at the inventor, his hands steepled under his chin as the inventor entered his office.

"Sir, I'm picking up signals from my time-space continuum monitors, it's a specific device that tracks down the movement inside the time-space continuum that is specific to the Ten Year Bazooka. I had already asked the Bovino Family when I first encountered their Ten Year Bazooka and was informed that only Lambo was in possession of it. The monitors are going haywire and are indicating a mass transport from the future to now." Gianini spoke loud and clear.

Timoteo sat straighter and opened his mouth to ask. "Can it tell you where the transport will land then?"

"From what I gather it is specific to the Tenth's room or just in the Sawada household. But the problem is when… it hasn't indicated when they'll drop off. Their passage is much slower than normal when travelling through the time-space continuum by use of the Ten Year Bazooka. But from calculations they'll drop off at around the time the last of their disappearances on its 2nd month mark." The eavesdroppers heard this and some of them silently pumped their hands in excitement.

Nana though looked a little troubled and felt something in her. 'My baby… Are you hurt? I know you are, so come back to mommy so that I can kiss the pain away…' she thought to herself. Though they explained the different things concerning Tsuna's bloodline such as his Hyper Intuition, she knew what she felt was nothing of the sort of the abilities the Mafia possessed. Her intuition as a woman and instinct as a mother was in overdrive as she felt her baby and his friends. She then entered the office of the Ninth never minding her fellow eavesdroppers and went straight to the front of the Ninth's desk.

"Timoteo-san I suggest that we ready some of the best doctors that our Family knows. You, maybe my husband, Xanxus-kun and Tsuna-chan might have your Hyper Intuition but I have my own. My intuition as a woman and my instinct as a mother tell me that we need all the help we can get. Though they are all going to arrive in one piece but they may not come at the best of conditions that is so to speak." Nana said with conviction.

The others were surprised at this but they always knew that though she may be sometimes airheaded but if there's one thing she was ever good at was being a mother and had a strong intuition as a woman.

"I'll arrange it so then… Is there anything else, then?" Timoteo said calmly. The others just shook their heads in negation.

"Alright then we shall be going to the Sawada house in 2 days to get my lost successor as well as his Famiglia." Announced the Kyuudaime.

Within 2 days Vongola Nono and Cavallone Decimo had gathered the best doctors they knew including illusive doctor Black Jack, which they paid more than enough. (A/N: I love Black Jack but not enough for me to actually obsess about unlike my other anime loves. Saying he's a good doctor is like saying Jiraiya, in Naruto, is just a bit of a pervert.)

And right into the prediction a large energy spike occurred in the Sawada household and revealed 7 heavily injured teens on the verge of collapsing holding a slightly awake Tsuna, 2 unconscious girls and 3 injured but not as heavily kids. An instant reaction occurred all the present doctors immediately leapt into action and started checking on them.

Bringing them to the Cavallone private hospital, the one they frequented after the Ring Battles, they started healing them. The most severe cases were of Reborn and Tsuna. Reborn managed to stay awake enough to tell them of the radiation that he was exposed to in the future. Shamal took care of Reborn saying he was more used to treating Arcobalenos than the other doctors. The other doctors didn't complain and let the man handle Reborn.

"Kyu-Kyuudaime…" Gokudera started in a very pained voice. "The Jyuudaime is… (Cough)... well, something is wrong…" Gokudera's lungs couldn't take it anymore and started coughing blood. Belphegor feeling compassionate at the moment held his former rival. "Don't strain yourself dynamite idiot the best doctors in the world are here to treat all of you." Belphegor for once sounded sane.

Gokudera stared at Belphegor and smiled a bit and finally passed out. Hibari watched this and turned to Dino while he was being helped by Kusakabe. "The dynamite herbivore is right." Wiping the blood from his mouth, continuing to speak. "Our enemies used a type of poison, we don't know what it is, and it's not in his blood not even the future's Poison Scorpion knew what poison got absorbed in him. Help… the… boss…" Hibari finally losing consciousness. The others were surprised to say the least especially Kusakabe. The other finally did lose consciousness after they heard the message they wanted to say was conveyed.

Ryohei struggled to stay awake and leaned closer to Kyoko and Haru and activated his flame with the last of his will power. Everyone there was surprised when a yellow flame appeared on the ring and even more when Ryohei touched the foreheads of Haru and Kyoko without burning the two. Miraculously the injuries that the two received just vanished and woke up.

"Oni-san! Stop it, you've used up all your energy in the battle just rest, please!" Kyoko exclaimed.

"Hahi! What Kyoko said is true Ryohei-san, please rest!" Haru exclaimed as well.

"Someone needs to explain what happened you're the only ones that extremely can. Extreme knockout time!" Ryohei finally lost consciousness.

"I'll take care of the Tenth then, Timoteo-san?" Black Jack said.

"Of course, please heal him then." Timoteo said.

Time Skip 5 days

The injured time travelers were all rested and awake but still tired from the fight of their young lives. They all seemed changed. They all asked to be put into one room and even Hibari was calm even with the boisterous noise brought by the other guardians. While Kyoko and Haru gave Timoteo and the others the rundown of things the guardian gave a more detailed story of what had happened. Reborn pitched in and gave his side of the story as well. They were all worried though; the tenth was still asleep even after the slightly epic battle of Doctor Black Jack with the poison that entered him. (A/N: I'll leave that to your imagination.) The doctor did say that he was fine and just needed rest though.

Scene Break

Nana was standing on the rooftop of the hospital clutching the railing staring out into the horizon. Iemitsu hugged her suddenly from behind but not startling Nana.

"What are thinking of Nana-chan?" Iemitsu whispered to Nana.

"Do you remember the times before the incident?" Nana answered.

"Yes, our wonderful Tsuna changed after that incident."

"Yes, change he did, I'm afraid Iemitsu… What if he changes again? I don't think I can look at him going through what he's gone through before. I had a feeling Reborn was going to bring change, maybe not enough to revert our little Tsuna but a semblance of it."

"And he has… Don't worry about it I'm sure that our son wont' go through that again."

"I hope Iemitsu, I hope. It's hard looking at our only son having no will to live since 5 years old. Enough that at 8 had become suicidal."

"He'll become a Mafia boss and he has friends that will do anything for him, but do you regret it?"

"Regret what? That he lost the one thing my family has always been proud of? The ability that is even stranger than that of you Mafia's abilities? Yes but I love our son the way he is." Nana answered. (2)

(1) I think that Kusakabe has always called Hibari, Kyou-san.

(2) Nana HAS to have some background, so why not make it a little bit more awesome!
