This fanfiction is set 10 years later after the Manga.

Notes: Chrome went to Namimori Middle once things settled down, and went to school with everyone.
Lambo and I-pin attended school in Namimori, but was transferred to the Mafia school in Italy.
Hibari started to call Tsuna 'Omnivore' due to past events and since Tsuna managed to win him in a fight, barely.
Tsuna became hotter, taller and of course, sexier. And also, smarter, more sadistic (rubbed off from Reborn), but still very kind and nice and also still values life. (This is MY version of TYL Tsuna)

Parings: Tsuna X Kyoko, Gokudera X Haru, Hibari X Chrome, Ryohei X Hana, Reborn X Bianchi, Lambo X I-pin.

"Juudaime (tenth), a letter addressed you from Namimori Chuu Gaksei (Namimori Middle School)." Gokudera said, passing an envelope to Tsuna.
"Eh? Namimori Chuu Gaksei?" Tsuna inquired.
"Hai (yes)." Gokudera confirmed.
"Ok..." Tsuna took the envelope and opened it. There was a folded piece of pristine white paper inside, a letter. The black lettering in a clear font was printed onto one side of it. The letter read,

"Sawada Tsunayoshi-san,
You have been cordially invited to class of 2XXX, Namimori Middle School's reunion.

The details are as follows:
Event: Class of 2XXX reunion

We hope to see you there!

Yours Sincerely,
Namimori Alumni Club Committee"

"There was a reunion dinner? I haven't seen any of these invitations in the past few years." Tsuna remarked.

"These invitations have been sent through email and for some, post, since we graduated from Namimori Chuu Gaksei." Gokudera explained calmly.

"I don't seem to have received them though..." Tsuna trailed off, deep in thought.

"Juudaime, that's what we all have been thinking about. This invitation letter was sent by post to Juudaime's home in Namimori." Gokudera informed Tsuna promptly.

"Oh, ok. So mum sent it over here?" Tsuna questioned.

"Hai." Gokudera answered.

"Call all the other guardians to my office now please." Tsuna ordered.

"Wakarimashita (Yes / formal way of saying 'understood' or 'I understand')." Gokudera said before bowing and taking his leave.

'A reunion huh, it would be interesting to see our classmates. Whether it would be fun, I'm not so sure about that.'

~10mins later~

"Juudaime, they have gathered." Gokudera informed as each guardian strolled in after Gokudera.

They lined up in the room, some disgruntled and some quite annoyed. There was only 2 people who were quite happy.

"Yo! Tsuna!" Yammamoto greeted.

"Tsuna-nii" Lambo greeted.

"Kufufufu, what is it, Vongola?" Mukuro 'greeted'.

"Hn, Omnivore." Hibari greeted.

"Bossu." Chrome greeted.

"Kyokugen (extreme) Sawada!" Ryohei greeted, loudly. Very, loudly.

"Good afternoon, minna (everyone)." Tsuna said with a smile, it was rare for all of them to gather, there were so many missions to complete, trainings to carry out and schoolwork to do (*cough* Lambo *cough*).

"Well, I'll get straight to the point. Namimori Chuu Gaksei is having a reunion dinner, and I'm thinking that we should all go." Tsuna said.

"Demo (but), Juudaime, not all of us attended Namimori Chuu Gaksei." Gokudera pointed out.

"Exactly, which is the reason why you are all going." Reborn said, stepping out from the shadows.

"Yep, just like what Reborn said, we are all going." Tsuna said with a somewhat sadistic smile, ignoring the stupid reasoning.

"What about the missions?"

"None are during that period of time."

"How long will we be there for?"

"We'll be there for a week. It'll be like a short break."

"I get to stay by myself?"

"Yes you do."

"Hn, fine then."

"I'll email you the details."

"Hn" Hibari acknowledged and walked out of the room.

Tsuna smiled, it was just like his cloud guardian, Hibari probably couldn't stand crowding much longer.

"Kyoko and Haru will be coming along with us as well." Tsuna said and looked at Ryohei.

"Kyokugen!" Ryohei replied.

"I-pin will also be joining us." Tsuna looked slyly at Lambo.

"Wakatta." Lambo replied, slightly embarrassed. He and I-pin had become closer, and Lambo had started to crush on her. You know, just uncontrolled teenage hormones. Or so Lambo thought.

"Alright then, Gokudera, please make the necessary flight arrangements. Everyone will be staying where they were staying before in Namimori, except for Mukuro, you will have to find a place to stay in. Chrome will be staying in my house. Is everyone clear?"

"Hai, Tsuna-nii."

"Yes Bossu."

"Wakarimashita."

"Hai, Tsuna!"

"Kyokugen!"

"Kufufu, alright then."

"You are dismissed." Tsuna announced and everyone left.

"It's time to get back to my paper work." Tsuna sighed.

His guardians were less destructive than before, and Bianchi had gotten over throwing her poison cooking at Lambo, when she realised that it was Lambo, not Romeo. Gokudera managed to get over his phobia of his sister. He now only had a mild stomach ache, which was bearable. Bianchi was banned from the kitchen; they got her a lab for her poison cooking experiments. Gokudera was also calmer, and his tolerance level towards Yammamoto had increased, thus there were only occasional explosions. Mukuro and Hibari's offices were strategically situated on the level which the training rooms were at. They fought each other whenever they met, and Tsuna had forced them to find a training room for themselves before fighting. Tsuna fought with Hibari once a week, and sometimes more, when Mukuro wasn't around. Each guardian had their own training room, and there were also extra training rooms, just in case one was under repair.

Paper work was definitely much less these days.

"Reborn, did you stop all the mail coming from Namimori?" Tsuna inquired, aiming his question at the tall man who finally got his body back.

"It would have been a distraction. If you don't finish this whole stack of paperwork, there will be no dinner for you tonight." Reborn stated simply, his gun already aimed at Tsuna's head.

"Hiee! Hai, hai." Tsuna panicked for a moment, before he started on his paperwork. He sighed; this is going to be a long day.
