Chapter one: Thanks a Lot, Lambo!

"Happy birthday, Decimo!" Spanner, Irie and Giovanni shouted, handing a sky blue box to their boss and friend, Tsunayoshi Sawada.

Tsuna laughed as he saw the specially made package. The whole box showed different elements of the sky, the lid holding a bright sun and white clouds. Two of the sides showed a storm, with lightning and rain falling from the black sky. Another side showed a field of flowers, shrouded in mist. The final side had the Vongola Emblem against a clear sky background.

"Thanks, guys!" The birthday boy exclaimed. "You must have spent so much time on-AHHH!" A scream erupted from Tsuna's mouth as he threw the box high into the air. His chair tipped backwards from the action, causing him to bang his head against the wooden floor. "Ow..."

"Juudime!" Gokudera shrieked. "Are you okay?"

"Wow, Tsuna!" Yamamoto whistled, shaking his head. "I haven't heard you scream that loudly in a while!"

"Or so feminine." Mukuro added with a smirk.

"Are you alright, Tsuna-san?" Yuni asked, bending over the older boy.

"I-I'm fine! It's just that... the b-box..."

Everyone quickly turned to look into the box. Inside was a large, metal cylinder, with an opening at one end and a handle and trigger at the other. The mafia members took a few steps back.

"What's wrong?" The ex-Arcobelano, Reborn, questioned in an annoyed tone.

"It's a Ten Year Bazooka!" Ryohei shouted, running to an extreme far corner.

"Get that piece of junk away from me." Hibari hissed coldly.

"I don't want to go to the future!" Byakuran whined. "There's no me there!"

"Hey! That's Lambo-sama's!" Lambo said indignantly. He tried to reach for it, but I-pin held him back.

"No, Lambo! You only cause trouble!"

"It's actually not a Ten Year Bazooka." Irie stated, stooping to pick up the infamous gift. "It's a Two Centuries Bazooka."

"Oh, sure, that makes us feel so much safer!" Gokudera snorted.

"Shut up and let him explain." Reborn commanded. The Storm Guardian immediately obeyed."Continue, Irie."

The inventor nodded a thanks. "Well, for Tsunayoshi's birthday, Spanner, Giovanni and I decided to make something special and totally unique to the mafia world. Spanner came up with this; the Two Century Bazooka."

Some of the girls clapped kindly, causing Spanner to bow and shoot a smug glance at Giovanni. "It was nothing. I came up with the two centuries idea since it had been that long since the time of Primo."

Giovanni huffed. "It's been four centuries, actually."

"No, Giovanni, I'm afraid it was two."

"Four."

"Two."

"Four!"

"Two!"

"Fo-"

"Two; now shut up before I bite you herbivores." Hibari glared at the two feuding inventors. They stared at their feet with new-found interest.

"The Two Centuries Bazooka works much the same way as the Ten Year Bazooka," Irie continued, adjusting his glasses. "With some minor differences. Because anyone who is shot with the bazooka from this time is sure to be dead in the destined future, we had to modify the bazooka to send its passengers to a exact location. We decided that Primo's Mansion was a good, traditional spot. The other difference is the time; instead of simply ten minutes, it's an hour longer for each additional member of the group shot by it."

"Since two-hundred years has been such a big leap for the Vongola from Primo to Decimo," Spanner concluded. "We thought that Tsuna might be interested in seeing the Vongola two-hundred years from his time."

"Sounds extreme!" Ryohei said loudly.

"Shishishi~I would love to see if Tsuna actually does ruin the Vongola with his foolish morals." Belphegor laughed coolly.

"I'm sure the Vongola is as strong as ever!" Enma softly stated.

"I'm not going!"

"What?"

Tsuna flinched slightly at the roar of questions and disbelief that exploded on his poor ears.

"Why not, Tsuna?"

"Is it dangerous, Tsuna-kun?"

"Haru could protect Tsuna-san!"

"BOO! Coward Tsuna~!"

"Stupid mermaid! Juudime isn't afriad of anything!"

"W-we could go and protect you, Boss."

"Can I still go, byon? Maybe they have flying cars!"

"Master won't even let you drive a regular car, so why would he let you use a flying one?"

"The apple speaks the truth~kufufu."

"Guys!" Tsuna shouted, waving his arms above his head, trying to gain the party's attention. "The reason I'm not going is because, whenever the Whatever-Year Bazooka is fired, something bad always happens! It's a pattern!"

"Haha!" Lambo suddenly laughed triumphantly, catching everyone's attention. They turned to where the cow child had placed himself inside the birthday box, holding the bazooka and pointing it towards the large crowd of guests. "Now it's Lambo-san's!"

"No!" Everyone shouted in horror. Some of the young men lunged at the mischievous young cow, but Lambo already had his hand on the trigger.

"Die, Reborn and Stupidera!" And the trigger was pulled.

Tsuna shielded his face upon reflex. But no pink smoke filled the room. Nothing happened.

"Ha ha!" Gokudera shouted and pointed at the confused Lambo. "It's broken!"

"What?!" Giovanni, Spanner and Irie asked simultaneously.

"But, we worked so hard on that!"

Byakuran patted the downcast Irie on the back. "Don't worry, Shoichi-kun! I'm sure you did your very best!"

"Even though it wasn't good enough!" The oblivious Ryohei added. Tsuna and Yuni glared at him. "What?"

"Come on! This is a party!" Kyoko tried to brighten Spanner and Giovanni's spirits. "Let's play some games!"

• • •

Sometime later, (after Mukuro finished cheating at all the games, Bluebell and Byakuran had eaten half the cake and Gokudera had successfully finished checking all the gifts for possible assassination attempts) Timoteo had an excellent idea to share with his guests.

"Why don't we take a picture of just the bosses? To sort of commemorate today?"

All of the bosses readily agreed. Tsuna, as the birthday-boy, sat down in a large, plush red chair, with Enma and Yuni on either side. Byakuran and Dino stood behind him, all five of them smiling as Lussuria prepared to snap the photo.

"Wait," Yuni said suddenly. "Long Champ-kun just went to the bathroom. Shouldn't we wait-"

"No no no." Timoteo said, shaking his head. "I'm sure he wouldn't want to bother us by waiting for him. Just take the picture, Lussuria; quickly."

As the guests were occupied with preparing for the pictures, nobody noticed little Lambo sitting in a corner under the window, tinkering with his bazooka thoughtfully. "Stupid people, breaking all of Lambo-san's weapons! How else am I supposed to kill Reborn if they keep taking my things and ruining them?" He paused in his rant, as a curious slip of paper caught his attention. "Lambo-san knows that's not supposed to be there." He pulled the tab, the paper easily slipping out.

"Maybe now Lambo-san's bazooka will work!" The cow child hopped up, grinning evilly. "I'll get back at that Loser-Tsuna for letting those meanies take my weapons!"

"Say Vongola!" Lussuria exclaimed to the bosses.

"Vong-!"

"Die!" Lambo shouted maliciously and fired the bazooka. The room was suddenly filled with a suffocating fume and thick, blue smoke. Nobody could open their eyes or mouths, but just groped about looking for a window. After what seemed like hours,Gokudera found one and threw it open.

The smoke soon vanished, bringing with it the strong smells. Just as everything seemed okay again, Adelheid cried out,

"Enma and the others are gone!"

{• • • Years later • • •}

A young man stood quietly on the stone veranda of his very old fashioned mansion, looking at his friends in the training grounds below him. A fond smile crossed his handsome Italian face. It was October and the autumn wind blew his red hair and stung his red eyes. He shivered slightly in his light, white dress shirt, but he didn't move from the railing.

He heard the gentle footsteps of one of his favorite servants behind him, but he didn't turn around. The next moment, there was a knock on the open wooden door and a unnecessarily loud voice called out, "Your tea, Decimo sir! Would you like it out here?"

"Yes, please." He replied.

"I said do you want it out here?" The servant's voice asked louder.

The man chuckled as he turned to face the young woman. "Aria, please remove the music."

"Huh?"

Walking up to her, the red head pulled back her long blond and red hair. As he had thought, a black ear piece was clipped around her right ear. He pressed a small button on its side. "I asked if you would please switch off your music."

Aria laughed, embarrassed. "Oh geez, sorry Decimo sir!" She showed him the golden tray in her hands. "I'm guessing you said to put this down somewhere, too?"

The man nodded. "Yes, on that table there. And I thought I asked you to call me Matteo?"

Aria placed her burden down and began to serve. "Sorry, Decimo sir. But old gram would have a fit if she thought I was being disrespectful to you in anyway. You know what a stickler for tradition she is." She smiled slightly as she thought of her great-grandmother.

Matteo nodded, a smile slowly making itself visible on his own face. "I know; I also know how hard it must be for you to visit her here. This is far less modernized compared to the up to date headquarters you're used to."

"You've got that right!" Aria blushed slightly. "I-I mean, yeah, I'm used to the newer technology and stuff. And this place, though it's pretty and grandmother enjoys it, I just can't help but find it... boring. And unnecessarily complicated." She leaned in closer to Matteo, as if about to share a great secret. "Do you know that we can't even get enough electricity in those outlets to power a vacuum cleaner that doesn't need someone pushing it? I mean, come on! Can you say 'ancient'?"

Matteo laughed outright. "I know this old mansion may not seem like the best place to spend your time, but think of it like a haven." He stood up suddenly and walked back over to the railing, gesturing for Aria to follow him. They stood together looking over the large, green expanse of the mansion's grounds. "A little peaceful island," he continued softly, "for the men and women of this technologically advanced world to escape to something that was so much more simpler."

Aria watched her boss' face and noticed a strange gleam in his bright eyes. Anyone who didn't know him would have said it was the look of a madman. Until her grandmother had explained to her that the young boss was perfectly sane, Aria was one of those people who believed he was slightly mad as well; he was only unusual in the way that he didn't get caught up in the fast pace of the world. That and the fact that he was a terrible romantic.

For a moment, enchanted by her boss' poetic words, Aria stared over the land in silence, thinking about her music player and her new computer that had the latest voice recognition program installed and how she was looking forward to a raise to buy a new, larger electric car. 'Maybe they're not really necessary...'

She gave her head a firm shake. "You sound like an old man, Decimo sir. A perfect Luddite."

Matteo let out his usual gleeful laugh again. "Thank you, ma'am." He looked as of he might continue, but something made him freeze. "Do you hear something?"

"Now that you mention it..." Aria looked around carefully, her brown eyes narrowed dangerously. "There is some sort of... buzz."

Matteo glanced up. What he saw made his eyes go wide. "Aria! Move!"

He grabbed the woman by her waist and pulled her out of the way just in time to avoid being made into a landing board for two screeching boys.

"Oh my gosh!" Aria screamed in surprise, sitting up and looking at the two figures sprawled out painfully on the veranda.

They were boys, not older than eighteen, with foreign, Asian features. Besides this, there was no other similarity between them. One boy had messy red hair and equally red eyes, which struck both Matteo and Aria as strange, because he looked so like the boss. The other boy was a brunette, his hair sticking up in no particular style and had large, kind, brown eyes, which looked slightly dazed, at the moment.

"Sorry~!" A playful voice called from the air above them. A young man with white hair was gliding on his very large, angelic wings. Under one arm hung a little girl, her black pony tail flapping in the strong wind. Dangling from his other hand was a blond man, with a large tattoo circling his neck.

"Byakuran!" The brunette addressed the winged man in an exasperated, panicky tone. "We would've broken our necks if Enma hadn't used his Gravity Flames to slow down our fall!"

"Oh, you over react, Tsunayoshi~!" The man claimed, landing gently in front of the boys and dropping his male passenger. "Reborn-san probably has your head so hard, a club couldn't crack it! The landing would have felt as soft as landing on a marshmallow~"

"Well I hope their's did..." The blond mumbled, his face in the concrete. He sat up, bruised and glaring at Byakuran.

Byakuran beamed at the boy as he let his other burden down gently. He brushed his hands. "Now then, where are we?"

A sudden click sounding from several guns was heard behind the five intruders. They wheeled around to see three guns, wielded by Matteo and Aria, aimed carefully at their heads.

"Who are you and what did you say about the Gravity Flames?" Matteo asked in a low, warning tone.

The boy named Tsunayoshi squealed loudly and threw up his hands in surrender. "We come in peace! Don't shoot! Don't shoot! I get enough of that in my time!"

Suddenly, Matteo lowered his weapon and a look of disbelief crossed his face. Aria tilted her head at him in concern, though she kept her eyes and guns trained on the strangers. "Decimo sir? You okay?"

"Decimo?" The little girl repeated in confusion. "What Family are you?"

"That's none of your-!" Aria's sharp answer was interrupted by Matteo.

"Vongola... you're the Vongola..."

Three intruders took a step back. The two on the ground got to their feet slowly. "What?"

"And you're Yuni and-and Byakuran!" Matteo pointed to the incredulous looking young man and girl. "Founders of the Millifore Family! And you..." He now pointed to the tattooed man. "You're Dino! The... oh, I can't remember what number, but you were once boss of the Cavallone Family! And you two..." Now he faced the terrified boys with wild, excited eyes. They squeaked softly as he spoke. "You are Tsunayoshi Sawada and Enma Kozato, Tenth Generation Leaders of the Vongola and Shimon Families respectively and the ancestors of my own Family."

"And just who are you?" The man named Dino asked, a wary smirk on his face.

"I am Matteo Sawada, Neo Vongola Decimo and Secondo Neo Shimon-Vongola leader."

Silence and tensity lay thick in the air around the veranda. No one moved or spoke. They simply stared at Matteo with a disbelieving and skeptical look in their wide eyes.

Finally, Tsuna spoke. "Y-you're... a Vongola... Boss?"

Matteo nodded. "Yes."

Tsuna paused before continuing. "Then... you know about me... because you're the boss... and you know about them... because their Families are... your allies?"

"Yes," Matteo repeated.

"Well... aren't you shocked to see us?"

"Sort of."

"Sort of?"

"Well, there is an old story... about you..." Matteo began uncertainly. "That you were once shot with a special time travel bazooka on your birthday and you and some of your allies-"

"Friends." Tsuna corrected harshly.

"Friends," He amended. "Disappeared for five hours. When you returned home, you never said where you had been or what you had seen. It's been a famous Vongola myth ever since. And... I'm guessing that you're all the bosses and you were... shot with the bazooka... and so now you're here?"

Tsuna bit his lip, wondering how he should answer. Finally, he muttered an affirmative.

Matteo suddenly let out a deep breath. "This is wonderful!" He shouted, surprising the bosses and his servant and simply scaring Yuni, who hid behind Dino. "This is terrific!"

"Decimo sir, I think you've lost it!" Aria shouted.

"No! This is just amazing! Simply astonishing! I can't believe that this should happen to me, during my time as boss. This is just... I can't even find the words!" Matteo grabbed Tsuna's hands and gripped them tightly. "Decimo... I can not express how amazing it is to meet Vongola's greatest leader... next to Primo, of course. And Shimon Decimo," He turned to Enma now, who back away discreetly when he saw the crazy light in the other man's eyes. "To think that I can meet you, the man who led the Shimon Family out of darkness so that they could see the light of the rest of the world once again. This is beyond an honor."

"U-um... thank you?" Enma stuttered. "But... why do you keep saying Neo Shimon-Vongola?"

Matteo looked surprised for a moment, but quickly shook it off. 'Of course there is no union yet,' he thought to himself. "Well." He clapped his heads and rubbed them together excitedly. "If you have but five hours to spend exploring this future world of mine, then we must not waste any of it! Aria, be a dear and run to get some more cups for our guests and then we shall be off to explore first the mansion, then the grounds and end with the growing town of Cielo! I just can not believe I am about to have tea with the most legendary mafia bosses of the twenty-first century! It's unbelievable!"
