Title: Running From the Vongola is NOT Good for Your Health

Genre: Adventure, Friendship

Summary: Tsuna and his classmates will go to Italy, thanks to Reborn disguised as Reboyama-sensei. Tsuna will try his best to hide his secret but what he didn't know was there was a reason why the whole class is going to Italy. When he finds out, he's in it for a big surprise. 4YL, Tsuna is 18 and is on his last year of high school.

Disclaimer: I do not own KHR. If I did, I would be the happiest person on earth.

It was just a normal day…. Well, as normal as it can be for the future Vongola boss, Sawada Tsunayoshi. Today was the school's annual field trip. Usually, the whole third year class will go to a boring place like the museum or the factory but this year was different. This year, they were going overseas! Different countries were assigned to the third year classes. It was just Tsuna's luck that their class had been chosen to go to Italy.

Italy. It was the heart of the mafia, a place of danger. Why, why did it have to be Tsuna's class? It could've been class 3-B or class 3-C but no, it has to be class 3-A, Tsuna's class. Tsuna knew that this was no coincidence. This was the work of his Spartan tutor who, Reborn, who happens to chaperone the trip as Reboyama-sensei. What was weirder, they were going to stay there for the rest of the school year. Meaning, 5 months. 5 months! How could Tsuna keep up his secret of being the Vongola Decimo?

Tsuna can remember the surprising announcement as if it was yesterday. Well, it was yesterday but that's beside the point.

(Flashback)

Class 3-A quieted down as their homeroom teacher, Nezu-sensei, cleared his throat loudly.

"Class, you're all aware that tomorrow will be the third year's annual field trip right?" Nezu-sensei said. "There's been a slight change of plan regarding the field trip." Murmurs broke out the room.

"Does this mean were not going to go to another bori- I mean exciting field trip to the museum?" asked one student.

"Yes, I can just stay home and sleep." Said another one.

"I was looking forward to the field trip. What a shame it has been cancelled." said a student, sarcasm dripping in his voice.

Nezu cleared his throat to gain attention. When everyone's eyes were on him, he started speaking once more. "Now, now class. The field trip has not been cancelled. There's been a change of the venue. Reboyama-sensei will explain more." As if on cue, Reborn, disguised as Reboyama-sensei, jumped on the teacher's desk.

Tsuna frowned. What was Reborn up to this time?

"Ciaossu, minna. This year, instead of going at the museum tomorrow, you'll be going overseas instead." Reboyama-sensei said.

'Reborn…. Always strait to the point….' Tsuna sighed inwardly.

Murmurs broke out the room once more.

"Overseas? But I don't have a passport!"

"Did the school suddenly got rich overnight? How can they afford an overseas trip?"

"I wonder if my parents will allow me…."

"What country will we go to? Russia? India? America?"

"I'm already excited!"

Nezu cleared his throat. "Quiet down, class. Reboyama-sensei is not yet done."

"A country has been randomly picked to be your destination. The country picked was Italy. Your first destination there will be Sicily. Your parents or guardians has been asked for permission beforehand. The class representative will distribute your passport and instructions." Reboyama-sensei said.

The class representative raised her hand. "Ano…. Reboyama-sensei, how did we have passports? As far as I know, I never applied for one…. And who will pay for the expenses?"

"It has been taken care of by a generous friend of mine and the whole trip will be sponsored by a company based in Italy. That company is called the Vongola."

Tsuna sweatdropped at that. How would Tsuna hide his identity of being the Vongola Decimo when most of the Vongola already knows who he is? And if his classmates knew then he would be breaking the Omerta. And it he breaks the Omerta, that means he'll get imprisoned! What is Reborn planning?

"Make sure you arrive 30 minutes before the departure. That is all." With that, Reborn left the room. There was a moment of silence when a student decided to voice out his question.

"Wait," said a random student. "Don't you need our signatures for our passports?"

(Flashback End)

The whole class gaped at what they say upon entering the airport. Right before their eyes was a very impressive looking airplane.

"Are we even in the right terminal?!" exclaimed Tetsuo.

"Isn't this the VIP terminal?" asked Minami.

"It looks like it's very expensive. Reboyama-sensei's friend must be really rich…." Hana muttered to her friend. Kyoko just smiled, already knowing what the situation was after seeing the Vongola crest at one side of the plane.

"Minna, we will be boarding the plane soon so make sure everyone's here." Said the class representative, Zuki.

She looked around, searching for anyone who might be missing.

"Where's Kozato-san?" she asked everyone.

"Ah~" Tsuna suddenly remembered something important. "Enma-kun won't be able to go because of….. umm….. family problems"

Tsuna knew that Enma wasn't able to go because he was called to Italy for an important meeting. Over the years, the Shimon famiglia has gained recognition among the other mafia families. Tsuna wouldn't be surprised if they met Enma at Italy.

"Hmm? Is that so?" Zuki said. "Well then minna, we will be boarding the plane in a few moments. Make sure your possessions are intact, your luggage has been sent ahead. We will be staying in Italy for….. EH?! 5 MONTHS?!" she said, reading on a piece of paper.

"5 MONTHS?!" echoed everyone else except Yamamoto who just laughed good-naturedly.

"That's a pretty long time to spend at Italy," he put on his trademark grin which made a few girls swoon.

"Anyway.." Zuki cleared her throat. "We will be saying at the Vongola mansion. The Vongola is the company sponsoring for our trip."

"Uh… Kaicho-san.." a girl, named Yuri, raised her hand. "How about our studies?"

"The Vongola will also provide us the lessons. Any more questions till we board the plane?" the ever so charismatic representative asked. No one raised their hands so they went in a single file line and started to board the plane.

"Wow," most of the students muttered once they saw the inside of the plane. Needless to say, it was very impressive. Chandeliers hung high on the ceiling above, expensive looking furniture was littered around the room, and there were butlers on one side of the room, ready to be given directions.

"Students, you are free to explore the plane but please avoid going to the topmost floor. It is a room for the owner of the plane and only employees are allowed there." A voice rang in the speakers, a voice that they recognized as Reboyama-sensei. Tsuna's classmates dispersed immediately. Some exploring, some ordering food from the butlers, and some sleeping.

Tsuna crashed onto a chair. This was going to be a long fight…..
