Prologue: The Invitation
Italy, Vongola Mansion
Letting another file join the big stack of completed paperwork, the tired brunette finally put down his pen and stretch. 'Finally done with the paperwork. For now, at least.'
Deciding to spend some well deserved time on the social media before his trusty right-hand man brings him more paperwork, the Decimo turned to his Luvaglio laptop, and loaded the Facebook page. As Tsuna checked the many notifications that had accumulated while he was clearing his paperwork, a new notification joined their rank. It immediately caught his eyes - an invitation to his middle school class reunion.
Now, that is nostalgic. The Vongola boss-to-be had not seen his middle school classmates since his graduation.
After he graduated from middle school, the then 15-year-old Sawada Tsunayoshi had moved to Italy to continue his high school education, together with his Storm and Rain Guardians, Gokudera Hayato and Yamamoto Takeshi. His male Mist Guardian, Rokudo Mukuro, had also tagged along, saying that he would prefer to not let his potential vessel stray too far away from him, while his female Mist Guardian, Chrome Dokuro, with her newfound confidence and independence, had chosen to stay in Namimori with her female friends. Tsuna's Sun Guardian, Sasagawa Ryohei, had also chosen to stay behind, since he wanted to be with his younger sister, Kyoko. Similarly, his Cloud Guardian, Hibari Kyoya, could not stand to leave his beloved Namimori.
As for his Lightning Guardian, Lambo, he was instructed by Tsuna to remain in Namimori, together with I-pin and Fuuta, under the care of Tsuna's mother, Nana, until he graduates from elementary school. That way, Tsuna could keep his youngest guardian out of the mafia for at least a few more years, and ensure that his mother had some company in his absence.
Many things had happened in these past few years, and Tsuna can't help but smile as he remembered each one of them.
Firstly, in the absence of Tsuna and Mukuro, Hibari had taken to fighting Chrome, occasionally at first, with the frequency of their fight rapidly increasing to a weekly, and then daily basis. This led Hibari to come to the conclusion that Chrome is the strongest female who is worthy of being by his side as his girl.
Onii-san's extremely good news came next. One day, while the boxer was doing his usual roadwork, he chance upon some members of the local yakuza, Momokyokai, terrorising the residences. It so happened that the said residences that particular day, were Kurokawa Hana and some of her neighbours. Feeling that what the yakuza members were doing was wrong to the extreme, and seeing that the 'girl in the photo' he saw in the future was in extreme trouble, Ryohei extremely went to their aid. Since that extremely EXTREME incidence, Hana's perception of Kyoko's elder brother changed for the better - The boxing club captain, though loud and often reckless, was less of a monkey then the rest of the boys she knew. About two months after the incidence, Ryohei officially graduated from being a monkey, when Hana finally agreed to be his extreme girlfriend.
It was only fair that Tsuna's loyal right-hand man get his chance at finding his own happiness. However, this took a lot longer than the Decimo expected.
At around the same time when Tsuna was to move to Italy, Miura Haru's father, was invited to teach in an Italian University, which was situated in the same town as the high school Tsuna and company were going to attend. Therefore, through a coincidental twist of fate, Haru also moved to Italy and attended the same high school as Tsuna and his guardians.
Though fate played its part and placed both Gokudera and Haru in the same class in high school (and also, very conveniently, in a different class from Tsuna and Yamamoto), Haru's constant proclamation of her love for Tsuna-san (which said Tsuna-san constantly turns down as best he could) did not help with deepening the relationship of the two. Luckily, fate does not give up easily. Being in the same class throughout high school, the two's constant bickering and competition for the top position in class (which Gokudera almost always wins), seemed to have an opposite effect on the two's relationship from what most might expect. Finally, on the day of their high school graduation, Gokudera-san and the Aho-onna, finally promoted each other to Hayato-san and Haru.
Tsuna, unlike most of his guardian, did not have his life laid out like a bed of roses for most of the past few years. Of course that was mainly due to the tortur-I mean tutoring by a certain hitman, whose methods could put the devil of all devils, Satan, himself to shame.
Well, to give the said hitman some credits, training the infamous Dame-Tsuna into the Decimo of the most powerful mafia famiglia out there is no simple task. Furthermore, with all the conflicts, time travelling, misunderstandings and other fights, the already dame Dame-Tsuna had practically no time to study, causing his grades to slip even further. The brunette's grades, after the representative battle of the rainbow, were so bad (which consist of big fat zeros for all subjects), that our beloved hitman decided to start teaching again from the basics, beginning with kindergarten materials.
Oh, isn't that so nice and kind of Reborn? ... NOT. Apparently, the words 'nice' and 'kind' do not exist in the Reborn dictionary.
A shiver went down Tsuna's spine, as he remembered the price he paid for his tutor's 'nice act of kindness'. This 'price' included bunny-hopping through a sea of landmines, playing dodge-bullet with a machine gun-equipped, trigger-happy Reborn as the opponent, cliff-climbing while blindfolded and with both hands tied behind his back, OH- and let's not forget the all-you-can-eat buffet of Bianchi's newest 'delicacies'. If not for all the hellish time spent with Reborn which had made Tsuna stronger, there would not have been a single atom of the brunette left.
However, on the bright side, the torturi- tutoring did wonders for Tsuna's studies. Reborn pounded (with the 'occasional' use of normal bullets, special bullets and bombs) all the kindergarten through elementary school's material into Tsuna's head within three months and went on to the middle school coursework. With the basics, and a lot more, reluctantly ingrained into his every brain cells (along with trying his very best to grow more brain cells to cope with the increasing difficulty level of Reborn's teachings), Tsuna could finally follow his school teacher's lessons with ease by the second half of his middle school education.
That was when the home tutor from hell decided to up the level of the young boss' education. After making sure that Tsuna's Japanese and English were good enough to rival University language major graduates, Reborn started teaching Tsuna various other languages, starting from Italian, followed by French, Spanish, Latin, Chinese, ect. ect... By the time Tsuna graduated from middle school, he was already fluent in both spoken and written Italian.
You would think that with all these extra language lessons by Reborn, Tsuna's schoolwork would once again suffer, but you couldn't be more wrong. After all, as Reborn himself always says, he was basically still a home tutor, the best there is. Under Reborn's 'careful' guidance, Tsuna could have easily ace any University entrance exams at the age of 15.
The world's greatest home tutor hitman had, of course, not forgotten about his toy-I mean, student's physical education.
Once things had settled down, and most of Tsuna's injuries from the battles had healed, Reborn started the brunette on some light training. Said 'light' training consisted mainly of daily roadwork around Namimori before school together with Ryohei (and sometimes, Enma got dragged in too) to start the day, sparring with Hibari as the pre-lunch exercise, hike up the death mountain - not forgetting to throw in fighting off a bear or two - as the after school workout, and 100 sit-ups plus 100 push-ups while getting ready for bed. The real physical training, started when they moved to Italy. Recalling those torturin-I mean training sessions, Tsuna would have gladly toured all levels of hell with Mukuro and personally visited Satan rather than undergo anymore of those trainings.
Fortunately, our beloved brunette's life was not all sticks and no carrots. The carrots, of course, came in the form of a certain Namimori Middle School idol, who was currently studying in the Italian University that Tsuna attended, and had recently agreed to be known to the whole Vongola Famiglia, as well as some other allied famiglia, as the Vongola Decimo's girlfriend.
Said school idol, as if on cue, happened to walk through the double doors of the Decimo's office at that very moment. "Tsu-kun, have you seen the class reunion invitation?"
"Ya, I just saw it. In fact, I am typing my reply now." said Tsu-kun, as he informed the class that he would once again be absent from their class reunion.
As the Decimo posted his reply, another post with a similar content appeared on the screen. It was by his best friend, the Simon Decimo, Kozato Enma.
"Eh~? You two are not going again?" questioned Kyoko with a small frown, as she look up from her hand phone.
"Yes, and you know why we can't go, Kyoko-chan." Tsuna defended, speaking for both himself and his best friend.
"But-" Kyoko began, but was interrupted by a sudden facebook message on both her hand phone and Tsuna's laptop. It appeared the former class president, Shirayuki Shizune, had started a group chat with everyone who's online.
[Shirayuki Shizune] SAWADA! KOZATO! WHICH PART OF 'DO NOT SAY THAT YOU ARE TOO BUSY TO ATTEND' DO YOU NOT UNDERSTAND?
Tsuna check the event description again:
Hey minna-san! Let's have another class reunion! This time, I am thinking of making it the biggest reunion yet, so, especially for those who have not attended any of the previous reunions, DO NOT SAY THAT YOU ARE TOO BUSY TO ATTEND. I want everyone to be present. So please list below when you will be free/not free within the month of September. It is going to be a three days two nights stay at an onsen ryokan. More detail will be provided once the dates have been confirmed.
Knowing that his attendance might bring danger to the rest of the class (plus, he was really too busy with mafia-related stuff), the young Decimo decided to try arguing his way out of the class reunion. It so happened that his best friend was thinking the exact same thing.
[Sawada Tsunayoshi] But I really am busy.
[Kozato Enma] Me too.
[Shirayuki Shizune] I gave you a whole month to choose from! There's no way you can't find a single day in which you are free.
[Kozato Enma] We can't help it if we are busy.
[Sawada Tsunayoshi] Plus you ask for 3 days, not 1.
[Shirayuki Shizune] Stop trying to find excuses!
[Shirayuki Shizune] Both of you are currently studying in an Italian University right?
[Kozato Enma] Yes.
[Sawada Tsunayoshi] Yes. Why?
[Shirayuki Shizune] I did my research. Both of you should be having Summer holidays from now until mid-September. You should at least have some free time!
[Kozato Enma] But...
[Shirayuki Shizune] NO BUTS!
[Shirayuki Shizune] Even the extremely shy Chrome Dokuro and the somewhat unsociable Shitt-P. has attended at least 1 previous class reunion!
[Shirayuki Shizune] What exactly are you busy with!?
The sudden question caught the mafia boss-to-be by surprise. He can't exactly disclose the real reason he can't go or the fact that it was the mafia that was keeping him busy.
[Sawada Tsunayoshi] erm... School project...
[Kozato Enma] ...Part-time job...?
[Shirayuki Shizune] -_-
[Shirayuki Shizune] I don't care what you are busy with. I want everyone to be present for this reunion. Sawada, whatever project you are doing, just somehow finish it before the reunion. Kozato, if it is just a part-time job, you should be able to take a few days leave.
[Sawada Tsunayoshi] But...
[Sasagawa Kyoko] The two of you should really just give up and go. :)
The last comment caused the brunette to look up at his girlfriend. "Kyoko-chan, why would you say that?" But before Kyoko can reply, the online chat continued.
[Shirayuki Shizune] See, Kyoko also think that you two should attend. I am sure the rest of the class misses the two of you.
[Sawada Tsunayoshi] Ya, right -_-
Tsuna can't help but be sarcastic when he recalled his past bullies who were said classmates.
[Kozato Enma] It wouldn't make that much of a difference if just two people don't go. You can still have the biggest class reunion yet.
[Shirayuki Shizune] NO! Everyone MUST be present. SO you two will be coming. End of discussion.
[Sawada Tsunayoshi] But...
[Shirayuki Shizune] END OF DISCUSSION!
[Shirayuki Shizune] If any one of you do not turn up, I will personally hunt you down. Even if you were to hide on the moon or in the middle of the milky way. SO COME!
Tsuna lets out a sigh. Looked like he and Enma-kun lost the argument. That was pathetic. He, alone, could outtalk a whole room full of mafia bosses but he just lost an argument against the former class president, a complete civilian, even with the help of Enma-kun.
Defeated, Tsuna turned to his girlfriend. "Kyoko-chan, why did you help Shirayuki-san?"
"It can't hurt to have a little fun once in a while." Kyoko-chan replied with that innocent smile of hers.
"It can." The brunette boss said bluntly. "I am going to be officially named the tenth boss of Vongola in October, and the class reunion is suppose to be in September. Many things can happen when it is so close to the inheritance ceremony."
"It's going to be okay." Kyoko rebutted, not ready to give up. "Yamamoto-kun and Chrome-chan had both attended previous class reunions before, and everyone in class is still safe. Let's just take this as a short break."
"It would really be nice to take a break, but you know that my position is different from theirs, Kyoko-chan." Tsuna sighed. "It may be okay for Yamamoto, Chrome and even Gokudera-kun to go, but, being the boss-to-be, my presence will unnecessarily endanger the rest of the class."
Kyoko was about to continue with her side of the argument, when a new voice interrupted. "Just make sure that your attendance at the reunion remains a secret from the rest of the mafia world. Then you can take the break from the mafia that you always wanted."
Looking toward the voice, the couple saw a teenage boy, wearing a black suit, complete with a black and orange fedora, where a green chameleon rested. The former Arcobaleno's body had grown about twice as fast as a normal person's would since his curse had been lifted, and it now resembled that of a 15-year-old teenager. The hitman tutor was standing by the doorway, and a smirk could be seen on his face.
"Reborn!" The hitman's student exclaimed. "Why must you tempt me like this? You were the one who taught me that taking a break from the mafia is impossible."
"Hmph. Good to see that you remembered that lesson." Reborn said, as he looked at his student with amusement. "But aren't you contradicting yourself? You want to take a break. Being so indecisive is unbefitting of a mafia boss. Besides, if you don't take a break now, you will never get the chance once you officially inherit Vongola."
'Reborn is right.' The young Vongola boss was starting to agree with his tutor when he realised that something was not quite right, courtesy of his hyper intuition. 'Why is Reborn, the ultimate slave driver, asking me to take a break?' "Reborn, you are planning something, aren't you?"
Starring innocently at the suspecting brunette, Reborn answered, "Why would you think that I am planning something?" Seeing that his student was not fooled by his act, the hitman added, "The reunion is planned by your class president, Shirayuki. I don't have any part in the planning process at all. I am just curious as to how you are going to act around those classmates of yours after so many years. It will serve as good entertainment for me."
'I knew it would be something like this.' Tsuna thought. 'If Reborn wants me to go, there's no getting out of it. Sigh...'
