XOver of Katekyo Hitman Reborn, One Piece and Durarara! XD this idea just suddenly popped into my head as I re-watched One Piece's 10th movie, Strong World.

Summary: Reborn has planned a meeting for Tsuna with two other leaders, how can this turn out? Good? Or bad? Find out yourselves!

Disclaimer: NOT mine!

Side Note : For KHR, the time is specified in the text ... For One Piece, the crew is wearing the suits they used in Strong World against Kumitate Shiki (It just seemed SO cool! XD So mafia like!) but no weapons except for Zoro's swords and Brook's cane... and For Durarara! Mikado, Izaya and Shizuo wear suits, and so does Anri, but a skirt instead of pants. Celty is in her usual attire.


"Tsuna, I've already arange a meeting with two other bosses." Reborn suddenly announced as he entered his office.

Tsuna had just recently officially became Vongola's Tenth boss just 6 months ago, and said teen was still getting used to things. So, Reborn thought that by inviting some other leaders of other groups other than the mafia would help his student know the concepts of being a boss.

"Eh? Wait, Reborn! Didn't I just meet all the mafia bosses last weekend?" Tsuna said as he looked up from his documents on his desk.

"Indeed you did, but," Reborn's shoned a mysterious glint. "The leaders you are meeting today are not your every day leaders."

"Huh?" it was all Tsuna managed to say.

"You'll Dame-Tsuna." Reborn said as he headed towards the door. "Just be sure to be at the Conference room number 1 with all your guardians at 1."

"You guys ... can you just behave yourselves for once?" Tsuna sighed as he sat in the middle between all his guardians waiting for his guests.

His guardias, Gokudera, Yamamoto, Hibari, Mukuro, Chrome, Lambo and Ryohei were literary about to have a war in front of him. In the midst of all the tension, a butler came in and notified Tsuna of the arrival of their long awaited guests.

"Let them in." Tsuna said in a tone that he had managed to improve throughout his years of trainning with Reborn.

As soon as the butler left, a lot more noise followed before the door opened harshly.

"Hahahaha! I'm first!" a guy with raven hair said as he walked in and sat in one of the chairs around the round table, oblivious to all the glares he was receivnig.

"That's not fair Luffy! you used your gomu-gomu power to get yourself here!" another guy with long nose and curly hair said as he went to the raven named Luffy.

"Yay! I'm third!" a round brown fluff ball with a pink hat said as he cheered as he entered the room.

Unlike Luffy, the other two newcomers felt the stares and cowered behind Luffy who was making himself comfortable with his feet on the table.

"Guys, don't go running aroud like that." a girly voice said as a orange hair woman walked into the room followed by five other people, or more correctly said, four people and a walking skeleton.

"Ah, warui! But you guys were too slow." Luffy laughed. Luffy's friends noticed the tension and straightened themselves.

"Sorry for our captain's stupidness." the orange haired lady said. "I'm Nami."

"No, it's ok." Tsuna replied with a softer voice, but still keeping his image of a mafia boss. "Please take a seat." Tsuna's voice didn't sound like he was asking, so everyone sat down around their captain.

"I'm Luffy." Luffy said as he grinned while tipping his straw hat.

"It's nice to meet you." Tsuna smiled one of his fake smiles. "Since we are missing one more group, I'd like to make introductions as soon as we are all here."

"Ok." Luffy said as he just leaned back and used the straw hat to cover his face.

While Luffy relaxed, he didn't notice the built up tension around the room. Everyone was tensed and each of them were analyzing the others.

"Decimo, the last group has arrived." the butler said as he opened the door to show five more people.

"Welcome to Vongola, please take a seat." Tsuna smiled. "I'm Sawada Tsunayoshi. Tenth boss of the Vongola Mafia Famiglia." Tsuna kept his act up.

"I'm Monkey D. Luffy." Luffy said; the raven had put his feet down when the new party came in. "Captain of the Straw Hat Pirates." Luffy said while seeming to be a bit more serious.

"Sorry for the lateness. I'm Ryuugamine Mikado." Mikado said with a boss like smile of his own. The room kept quite a minute, waiting for the raven to say more; realizing this, Mikado spoke up. "Leader of the Dollars and head of the D Corps."

"This are my guardians." Tsuna said signalling to the people around him.

"I'm Gokudera Hayato. Vongola Decimo's storm guardian and right hand man." the silver haired man said with a glare.

"Yamamoto Takeshi. Vongola Decimo's rain guardian." Yamamoto said with a calculating smile.

"Sasagawa Ryohei to the EXTREME!" another silver haired man stood up and yelled. "Vongola Decimo's sun guardian! Who would like to box with me to the Extreme?"

"Shut up, turf top! It's no time for boxing!" Gokudera also stood up and yelled at Ryohei.

"What? It's always time for boxing to the extreme!" Ryohei yelled back.

"Maa, maa, let's calm down." Yamamoto said trying to sooth things out; unfortunately, that wasn't working. Tsuna was used to this kind of pattern and knew that if he didn't stop them soon, this meeting would go nowhere.

"Proceed with the introductions." Tsuna ordered. Everyone in the room got the chills from the tone and quite down.

"Yare, yare. You've made Tsuna mad." a teen said with a smile and a closed eye. Even with the slight tease, no one dared to stand up seeing as Tsuna would not just tell them to shut up the next time. "Vongola Decimo's lighting guardian." Lambo finished.

"Kufufufu, the little rabbit has gotten so fierce lately. I guess being around an Arcobaleno for long is not a good thing." Mukuro smirked. "Vongola Decimo's Mist guardian."

"Dokuro Chrome. Mist guardian." Chrome said besides Mukuro.

"Hibari Kyoya. Cloud guardian." Hibari said accross the pineapple duo.

The tension was clear as glass in the air, but some didn't seem to notice.

"I'm Nami. Navigator of the crew." Nami said with the most innocent smile she could muster. 'If this a mafia building, there should be lots of gold somewhere.'

"I'm Roronoa Zoro, the swordsman." a man with short green hair and three swords beside him said.

"I'm Sanji, the cook." a blonde stood up and bowed like a gentleman would. "Free to service the girls at anytime."

"I'm the Great Usopp-sama! I'm the greatest sniper in the universe with 5,000 followers!" the guy with a long nose said, but no one seemed to care.

"I'm Tony Tony Chopper," the brown fluff ball had to stand up in his chair to to reach the table. Almost everyone in the room had the same thought, 'Wow, a talking racoon!', but Chopper snapped them out of it. "And I'm not a racoon! I'm raindeer! I'm a raindeer and a doctor!"

"I'm Nico Robin." a raven woman said after a few chuckles. "An Archaeologist."

"I'm Franky!" a man with glasses, big arms and a blue star tattoo said while doing a weird pose. "I'm the Super Shiqwright of the Straw Hats!"

"Yohohoho, my name is Brook. I'm a very skilled musician." the skeleton stood up and bowed. There seemed to be a serious silence as Brook walk towards the raven girl in Mikado's group.

"Hello, Mademoiselle." Brook said as he took her hand. "May I see your pa-"

Brook was cut off with a kick from Nami and Sanji, surprising almost everyone in the room.

"Don't ask a little girl that!" Nami and Sanji yelled.

Many stared at Nami wide eyed, while some others like Mukuro kufufu'd. It was rare to see a woman like Nami be so harsh and have such force.

"Um, may I know what he was gonig to ask?" the raven girl asked.

"Oh, it's ok, you don't want to know anyways. Are you ok?" Nami said as she checked the girl for any injury while Sanji was still beating some sense into Brook.

"I'm ok, thanks to you." the girl said while standing up and bowed at her. "Thanks. I'm Sonohara Anri. Mikado-kun's secretary."

As Anri said this, everyone sat back down and let the introductions continue.

"Maybe you should also tell them about Saika, that way there wont be any kind of confusion later." Mikado suggested. Everyone stared at the girl, waiting. There was more to this innocent little girl?

"Ok." Anri said and faced the other occupants of the room. "I'm the current owner of the demon sword Saika." Anri took the sword besides her up, but did not unsheath it which relieved the others.

"Anri-chan is so cute. the raven man besides Mikado said with a sly smirk. "Orihara Izaya and I love human kind." Izaya said as he stood up with his hands stretched wide open.

Somehow, everyone in the room knew that it was a lie, except some few naive exceptions.

"Damn flea." the blonde on the other side of Mikado muttered.

"Hm? What was that, Shizu-chan?" Izaya teased, but before hell could break loose, Mikado saved the day.

"Izaya." Mikado looked at the raven with so much overwhelming confident that it was scary.

"If Mika-chan asks." Izaya said as he sat back down.

"Please, Shizuo." Mikado said, still keeping his attitude.

"Heiwajima Shizuo." Shizuo said with a grunt.

"Thanks." Mikado's personality dropped to a softer one, but not much. "And that is Sturluson Celty." Mikado said as he pointed towards the woman with a yellow helmet.

"Um, we'd appreciate it very much, if she could take her helmet off." Tsuna said with a sweet voice while it seemed to be demanding.

"Ah," Mikado seemed to hesitate before turning towards Celty whom just took a PDA out and typed something.

[It's ok, Mikado.] It read. Everyone became more curious and more careful while waiting for the woman to take her helmet off.

Celty typed something in the PDA and passed it to Mikado to read it out loud as she slowly took off her helmet.

"Please do not scream." Mikado read, but what followed was not utter silence.

"Wahh!"

"Cool!"
