I read this kind of story in HP section so I think I can give it a go, did I have to ask permission first? I will take it down if I have to but I saw lots of people do same kind of story as long as they didn't copy the plot.

This is the second KHR story that actually written before Reunion of the Sky, hope you like it!

7X7X7 rules of Vongola's mansion by Sawada Tsunayoshi aka Decimo

Guardians, explosive material and firearms are not supposed to be aimed at your fellow guardians especially inside our mansion with exception for training room. That room is fireproofed by Souichi and Spanner for a reason, you know?

~by Vongola Decimo

Tsuna was used to destruction of his mansion to the point he was sick of it. His guardians tend to be explosive most of the time with Hayato and Lambo on the top of the list, no wonder Reborn said storm and lightning are brothers. Regardless how much they bicker, Tsuna thought wryly. He turned to the fainted boss of Serpente family, and his daughter who was half conscious from the looks of it.

"Don Gildo, Signora Ginevra! Are you alright?" He asked worriedly.

The Mafiosa nodded, "Yes… Don Sawada, but what was that?"

The Vongola boss smiled sheepishly, part of him was glad the lady forgot about her and her father's not so secret plot to seduce the young boss to accept Ginevra's hand in marriage. He had enough of her sly advance in their forty minutes stay in his mansion, "Oh… that probably just my mechanic's failed experiment, or our rival family attacking…"

She paled at that, "Wha… what?"

"Oh don't worry… my men will safely escorted you and your father back to your headquarter." He said then yelled to the Lambo shaped hole, "Lambo! Escort our guests back to their car!"

Lambo climbed up through the hole, looked a bit singed but mostly fine. "Yes boss…"

That night

"Thank you to get me out of that meeting…" He started, eyes twitching when the storm and thunder beamed. "But the damage that done to meeting room and corridor not worth it."

Hayato gulped, "I am sorry… Juudaime."

Tsuna sighed, "It's fine… I am used to it." Then he stretched out his hand to Gokudera, "So Hayato… the bill?"

The silver haired Italian gulped, clutching the paper on his hand. "Erm…"

Lambo snatched the paper and handed it to Tsuna, ignoring Gokudera's irritated yell. "Here boss…"

Tsuna's eyes widened when he saw how many zeros written on the bill and he fainted on the spot, "I haven't get used to the zeros…" He moaned painfully, when Gokudera cried his name followed by Lambo when their boss collapsed.

Pranking my fellow guardian's pet to piss off the owner is a low blow, and my boss is not Mukuro-radar therefore waking him up in ungodly hour to track down certain pineapple-headed illusionist is unacceptable.

"Omnivore…"

Tsuna's eyes shot up open as hyper intuition alarmed his brain of impending doom. "Kyoya?" He rasped unsurely, "This is… what?" He glanced at the clock on the wall, "3AM in the morning! Why you wake me up?" He groaned when he saw the door of his room had collapsed. Why Hibari didn't bother to knock like other civilized human? Or maybe it knocked down because HIbari tried to knock? Knowing Hibari it was probably the latter.

"Shut up." He growled, "Where is that pineapple herbivore?"

The Vongola boss sighed, why his mist and cloud never tried to be civil at least until sunrise? "How should I know?"

Hibari glared harder, "You can sense him…" He stated.

"Yes…" Tsuna admitted wearily, "But tell me, what did he do this time?"

"Pineapple! Pineapple!" Tsuna's attention was drawn to yellow bird that hovered above Hibari, his eyes widened at the sight. Hibird now had spiky fur on the top of its head with zigzag line in the middle. "Evil! Evil! Bite to death!" Hibird chirped as angry a bird could sound.

No wonder the cloud guardian was pissed, somehow the illusionist managed to cast an illusion on Hibird's head. Tsuna face palmed, "MUKURO!"

Appropriate reason is required to not attend guardian's meeting, and it's not a meeting where you can have representative in your place unless the said representative could survive your fellow guardian's antic which unlikely.

"Kusakabe-san!" Tsuna shouted activating his HDW mode to catch Hibari's right hand man who had been blew away through meeting room's ceiling. On the background his guardians minus Hibari and Chrome were busy ripping each other out, Yamamoto was laughing as blocking Mukuro's trident, and Lambo crying and running around like headless chicken.

It was just how their meeting went downhill in monthly basis if Tsuna happened to make his guardians waiting in meeting room without his supervision, it was not his fault suddenly Shoichi needed him to sign one more stack of paper, He only made them waiting for ten minutes! But today Kusakabe Tetsuya attended in place of Hibari. Too bad the ex-prefect was caught in crossfire and almost became a satellite if not for Tsuna who caught him before he could fly pass stratosphere.

"I hate crowding…"

"I know, but is your hate of crowding worth Kusakabe's life?" Tsuna asked his strongest guardian with a frown on his face.

"Hn?"

Tsuna rolled his eyes, "I am not going to guess what is your hn means Kyoya." His boss shook his head, "Your hate for crowding is not a reason Kyoya, and for his safety sake Kusakabe is not allowed to be your representative. You know how violent your fellow guardians some… I mean most of the times. And there is a reason why table in our meeting room is big and long, you can sit in the corner and use intercom to talk and hear us. I only ask you to bear being in the same room with us."

"Hn."

Tsuna groaned, " Why it have to come to that?"

Hibari turned his face away, arms crossed. "Che."

He gave up, "Fine!" Tsuna growled, "I will spar with you after next month meeting!"

The skylark's lips curved down, "Hn."

"Fine! Not spar! I will fight you! Happy?" Tsun threw his arms then slammed it o his desk.

Lambo was listening from behind the door with I-pin, an empty glass pasted on his ear. "How the hell Tsuna-nii can translate Kyoya's grunt?"

I-pin shrugged, "I don't know, does Hyper Intuition works for that too?" She asked innocently.

Being mafia and an adult doesn't mean you have privilege to ignore time and those who need their rest at night. So please keep it down if you had to do something in ungodly hour.

"EXTREMEEEEEEEEEEEEE!"

BOOM!

Tsuna rubbed his eyes, yawning when he saw what time it was. "Five AM, too early for explosion." But as the boss he had to wake up and take care of his guardians, he didn't need his hyper intuition to know what happened. He sat up slowly then exited his room. He walked lazily to his cloud guardian's headquarter, wondering why he couldn't get peaceful morning once in a while.

Tsuna even didn't flinch when he saw his sun guardian had his head went through tatami mat and wooden floor, if Tsuna was not too used to it he would think Ryohei had lose his head. On the shoji door Hibari Kyoya had a scowl painted on his face, and because of experience Tsuna knew Hibari was not just angry but he also had a headache the size of Sicily because of low blood pressure. Hibari's sensitive ear also no helping when Ryohei was around.

"Kyoya, go back to rest." Tsuna told him, "I will ask medic to send medication to you as soon as possible." It will help Kyoya's headache, at least he would be less cranky later.

"Hn." That was a grateful grunt, Tsuna concluded.

Then he turned to his sun guardian, carefully diggingRyohei's head out from the floor. "That's one extreme way to shut someone up." Tsuna commented.

Ryohei looked up, grinning like a loon. "Did someone said EX…" Tsuna grabbed Ryohei's mouth, clamping the boxer's mouth in the process. "Ho hoss hut horhingh?"

Tsuna sighed, Ryohei might be like an older brother figure to him like Dino but sometimes he wondered why Ryohei could be so dense and suicidal despite of being the only one in his family who had married. "Can't you please… don't wake up before sunrise just to scream your head off? And Hibari's quarter is off limits in the morning, I told you many times he is cranky in the morning because of low blood pressure." A pause, then Tsuna narrowed his eyes dangerously. "Did I make myself clear?"

Ryohei nodded numbly. "Yes boss." Tsuna was ten times scarier than Hibari when he didn't get enough sleep, Ryohei wondered since when violent tendency if his sleep disturbed of Reborn rubbed off on Tsuna.

This story rely on your cooperation a lot ^^ Please submit ideas of rules later I will post rules that I received then you guys can vote which rule you wanted to read. BTW here some rules I make... ^^

-Any pineapple related joke in front of Mukuro is strictly prohibited. Mental trauma resulted is not Vongolas's responsibility either.

-Those who use sharp and pointy weapon, please note that trees and everything that grows in Vongola's garden are NOT for you to practice your weapon on.

-Lambo's afro is not four dimensional pocket like Doraemon's so dear Vongola's mechanics, no shaving Lambo's hair to figure how it works.
