Author's Notes:

Just a heads up, this story is a very, slightly AU, but you guys won't notice it until the later part of this story. Also, this is my first time ever writing a fic with a lot of characters so I'm not sure if I had all of them in character. Do tell me if they aren't, okay?

Disclaimer: Katekyo Hitman Reborn will never be mine. Never has, never will be. I only own this story.

Chapter 1

Bright sunlight entered the large glass windows, filling the hallways full of lavish paintings and other works of art with light. The deafening, yet comforting silence that permeated the hallways was soon broken as the sound of footsteps, padding quietly through the carpeted floor, were heard and a figure came walking.

He was a tall man wearing a suit, although the coat was left unbuttoned, revealing the dark blue shirt and black tie underneath. He had a small smile on his face as he walked in long strides. On his hand was a folder which he held carefully while the other had was kept inside his pocket. The man exuded an aura of calm around him and anyone who met him along the way and greet him would be greeted back with a cheerful smile before continuing on his way.

He reached a crossroad where he slowed down and turned to the right where he was met with the sight of another hall decorated with various works of art, before slowing down again and turning left when he reached another crossroad. To anyone else, it would seem that the man acted as if he was lost and merely guessing at which way to go, given that the mansion had hundreds of passages and hallways, but to him, everything was just a habit that formed from the numerous times he got lost in the mansion.

Smiling a bit wider at the sudden memory, he took another left that would have been the last turn he'd make to reach his destination, but that changed a year ago and now his usual route had changed. Large oak double doors at the end of the hallway came to view as he continued to walk but just as he was a few meters away from the door, he slowed and turned to his right, where a similar door stood at the end of the hallway.

Stopping in front of the door, he brought his hand to knock on the door three times. "Come in." Came the short, and somewhat irritated reply seconds later and he couldn't help but grin as he opened the door.

"I'm back from my mission." He said, taking in the somewhat neat yet messy look of the room as he closed the door behind him. An irritated sigh was heard from the person sitting behind the desk and didn't even bothering to look up. "And your report?" the man behind the desk grumbled tiredly as he signed another paper before placing it to the stack beside him.

The man carefully walked towards the desk, mindful of the stacks of papers placed beside it, as he held out the folder for the other man to take. "Here." He said, making the man sitting behind the desk finally look up at him and it was only then that the man notice how tired the other was

He smiled sympathetically as the other took the folder and placed it on the right side of the desk instead of opening it and read its contents. "You should take a break Gokudera, you look like you haven't slept for days." He offered and instead of receiving the usual off-handed remark or an irritated scoff from the other man, he merely received a grunt in return. "I haven't." The man said as he leaned back on his chair and ran a hand through his silver hair. "If I did take a break I'm sure I won't wake up for two whole days and then all of these," he waved to the stacks of papers standing around his desk "would've piled up even more and then I'd never really be able to take a break." He finished, making the other man smile in understanding before he noticed something and blinked in surprise.

"Well, that's true, but I thought you were almost finished with everything? If I remember correctly, you were almost done with these when I left two days ago." He asked as he looked around the desk, the paperwork had increased almost twice in just two days. Gokudera let out another sigh, although this one sounded more irritated and angry than tired. "It's because of that stupid cow." He answered grudgingly as he crossed his arms over his chest. He was so close to finishing the paperwork. So close...

"Well, I'm sure Lambo didn't mean it." Yamamoto laughed while scratching the back of his head, which earned him a glare from the silver haired man. "Yeah, and I'm pretty sure Mukuro, Hibari and the Varia didn't mean it either." Gokudera scoffed, his aura turning more murderous with each name mentioned.

Years ago he would've exploded and ran off after the young Bovino (he couldn't run after Hibari, Mukuro or the Varia even if he wanted to) threatening him with dynamite at almost everything the boy did. But after years of living under the same roof with psychopaths, perverted pineapples and idiots running around, he got used to it. Not to mention the anger management classes he was somewhat forced to take.

Yamamoto laughed, not sure what to say after hearing that since he sometimes helped the other with the paperwork and had suffered the same fate. "It's not funny you baseball freak!" Gokudera screamed as he threw a paper weight at Yamamoto who easily dodged it. "Why don't you try sitting here all day doingnothing but reading and signing stacks and stacks of papers that come in everyday with no sleep and no breaks so that it won't pile up anymore and when you finally think you're done and finally free from it, you'd receive fifty more stacks just because Lambo had another fit and decided to randomly throw a grenade or Hibari got pissed, or find out that Mukuro was bored so he harassed a mafia don and the Varia just thought it'd be fun to blow up a whole city!" he exclaimed, panting a little at the sudden outburst.

"Calm down Gokudera." Yamamoto said, raising both his hands in a calming manner and Gokudera slumped back into his seat, too tired to even argue, and let out another sigh. He never knew that doing paperwork was this tiring. It wasn't that he didn't know how to do the paperwork, heck, it was actually easy. Just read and check if everything was okay then sign it and you're done. Besides, he used to help out Tsuna from time to time so he knew what to do, so that wasn't the problem. The problem was the sheer amount of paperwork that he had to do. A huge amount of paperwork meant repeating the same process over and over again. And if you're working in Vongola, the paperwork would never end and you'd be stuck in your office for a very long time.

Gokudera groaned. He'd rather be outside doing dangerous missions in some corner of the world than being stuck in his office doing paperwork. No. He'd rather fight Hibari than do all the paperwork. It was just that bad.

"This is too much. Now I understand why jyuudaime often escaped the mansion." He said, almost whining and Yamamoto just smiled sympathetically. "Yeah, and then you'd turn the whole mansion upside down just to find him only to realize he went outside." Yamamoto grinned, before it turned into a sad smile. "It's been a year, hasn't it?" he asked and Gokudera merely nodded, his demeanour suddenly turned somber. "We still haven't found anything about where he could be." He said

Both guardians fell silent as they remembered their beloved boss. It had been a year since Tsuna disappeared and none of them had any clue as to why or how. At first they thought he had just taken a break for a day or two, which he often did when he was trying to escape the paperwork, but he didn't return the next day or two nor did he leave any note or message behind. Then they though he had been kidnapped and Reborn had ordered a search of the mafia famiglias as well as the countries and places that Tsuna might have gone to for whatever reason why. But they found nothing. Then they thought that the ten-year bazooka might've had another malfunction and sent Tsuna to the future again just like what happened ten years ago.

But they had crossed that option out as soon as they realized that Lambo was away on a mission with I-pin when he disappeared. They even had Lambo use the bazooka on himself to make sure that Tsuna really wasn't thrown into the future a few times to be sure and none of the mafia famiglias had technology that was as advanced as the Vongola's and the Bovino didn't make another bazooka other than the one Lambo had.

This left Reborn and the guardians at a loss as to what happened to their beloved boss and where on earth he was. Their boss wasn't kidnapped or transported to a different world or time frame. No. Their beloved sky had simply disappeared.

And as much as they would all like to keep on searching for their boss, the famiglia wasn't going to run itself, missions had to be done, alliances to make, subordinates to watch over and the guardians couldn't just leave their responsibilities behind. So Gokudera, being the right-hand man, had to take up the position as the acting head for the famiglia with help from Iemitsu, although he refused moving in to Tsuna's office, saying that he wanted to keep the office as is for when Tsuna returned, and settled himself in the room next to it instead.

Gokudera ran a hand through his hair again before rubbing his tired eyes "I'm guessing you found nothing about jyuudaime while you were out." He said, his words sounding more like a statement than a question since he already knew the answer. Yamamoto shook his head "No, none at all." He answered somberly.

Even when they had decided to return to their responsibilities in the famiglia, they had never stopped searching for Tsuna. During their free time or when they had finished their missions earlier than expected, they would, more often than not, use it in search of their boss. Even Hibari and Mukuro did so on several occasions, but they would always return empty handed.

"Hey, Gokudera?"

"What?" Gokudera looked up at Yamamoto, who had a thoughtful look on his face. "Why do you think Tsuna would disappear like that?" he asked and Gokudera shrugged "Who knows." After all the search they had done and all the meetings held, they had somehow accepted that since Tsuna wasn't kidnapped or transported elsewhere, the remaining reason that could answer his disappearance was that he left; although no one could think of a reason why.

"Jyuudaime isn't the type to suddenly leave for some reason or another, although it's quite hard to think of why he would leave." Gokudera said as he straightened up against the chair, deciding that he'd had a long enough break and that he should start signing up the papers lest it increase again. "You can leave now, if you want. I still have these to finish." He said as he started signing the papers again. Yamamoto didn't leave though, and still had that thoughtful expression on.

He looked at Gokudera who was once again signing papers "Hey, do you think that incident last year had something to do with it?" he asked and Gokudera stopped in the middle of signing a paper before looking up. "What incident?" he asked and Yamamoto moved closer to his desk. "You know, that incident when a sudden beeping sound broke their conversation and Gokudera pushed a glowing red button on the console placed on the left side of his desk and the screen placed on the wall facing his desk came to life showing Shouichi looking a bit anxious "What?"

"Gokudera-san, Yamamoto-san, Reborn is calling all the guardians for a meeting." Shouichi voice came through the speakers and Gokudera and Yamamoto shared a glance before Gokudera returned his attention to the screen. "Did he say about what?" he asked and Shouichi nodded. "Yes. He said he got a call from CEDEF a few minutes ago and Sawada-san and Basil are on their way here. Sawada-san said it was urgent" He explained.

A look of surprise flashed through both Gokudera and Yamamoto's faces as they heard what Shouichi said. Aside from them, CEDEF was also trying to find anything that could possibly lead them to Tsuna. Iemitsu even created a team headed by himself, and now, Iemitsu was coming along with Basil, who was also a member of that team.

"Wait, does that mean..." Yamamoto spoke, stepping closer to the screen and Shouichi nodded "They've found him." He confirmed and he couldn't help but smile as he saw the relieved expressions of the two guardians.

"They found Tsuna."

Author's Notes:

And there you go! Chapter 1! I hope you guys like it. And I dearly hope that I got their characters right. If they seem a bit OOC it might be because I decided to make them a little more mature since this is set ten years in the future... and by then I'm sure they would have changed, somehow. Anyway please R&R! I already have a few chapters written here but I'm not upload any until I receive some reviews -insert evil laugh-
