Has anyone ever thought of what would've happen if a Mary Sue becomes a legitimate villain and a threat? Well because of that, a new plot bunny came and gave birth to this story.

Besides that, has anyone notice anything about Tsuna's low self-esteem? In the anime and manga, they only either hinted it or make a subtle reference about it and it has become one of my favorite things about Katekyo Hitman Reborn! It's also one of the reasons why Tsuna is my favourite character in the series and I just generally feel bad for him.

And before we begin, can someone explain to me the difference between a famiglia and a family? It has always been confusing to me and I don't think I want to make a mistake over this. I would really appreciate it if anyone would be willing to explain it to me.

Disclaimer: I own nothing besides this plot and the unimportant minor OCs I added in my story.

In the Mafia World, it is expected of every famiglia to be at least prepared if something concerning or life-threatening were to occur. However every once in a while, there will always be something so surreal and questionable that it would be taken into another category for consideration. It was because of this, there was a meeting in the Vongola Mansion.

In a darken meeting room where a scarlet sheet of curtain had shut out all but a single ray of light, Vongola Nono sat by the head of the large oak table with a slight frown. He had taken a notice of the way his men fidgeted with their hands by tapping their index finger in a rhythmic motion, or the occasional grunts that held impatience as they sat along the sides of the table in a continuous row. A white projector screen was near the opposite of the table where Nono sat. Nono then cleared his throat,easily captured the attention of his men in this heavy silence.

"Antonello," Nono began "Have you got what I asked for?"

Antonello, a young man with short brown hair and eyes, looked up sharply with his voice cracking up from every syllables that had been pronounced. "Y-Yes sir! It's right here."

Antonello stiffly marched towards Nono and handed him a brown envelope. Nono flashed him a quick smile of gratitude, reassuring him for a brief moment before Antonello headed back to his original place. All eyes were now on the brown envelope as it revealed a folder in the inside.

"You all may have recently notice that there is a sudden change in some of the important figures in the world." Nono said, leaning forward with his hand folded on top each other.

"Yes." A man with a gruff voice responded, "We've heard that their attitudes had changed. It's almost as if they had become another person."

"That's right." Nono confirmed, "Not long ago, there had been rumors spreading around the mafia underworld. They said that the important businesses and companies had suddenly become extremely successful because of the drastic change in the CEO's attitude. But now about a week ago, something similar has happened to a close friend of mine, the Coltello Boss."

The projector turned on and within a minute, two pictures of an elderly man was seen. The first image on the right was the Coltello Boss smiling warmly beside Nono. His bright green eyes dulled slightly from the bags underneath and the tired wrinkled face held decades of wisdom and patience. His navy blue sweater could easily give him the impression of a gentle grandfather. However in a peculiar contrast, there was something clearly wrong about the picture on the left. Instead of having a genuine smile, the Coltello Boss' toothy smile was one filled with fraud. Despite being an elderly man, the wrinkles he previously had was now non-existent and in its place, was a glimmering smooth skin resembling an artificial sun. He was dressed in a perfect business suit that consist of a distracting wrinkle-free surface and his eyes were filled with callous as it sparkled with hypnotic colours of the rainbow.

A heavy silence settled. Some people's mouth opened slightly while others clenched their teeth. It was obvious that everyone within the room had been taken by surprise by the unsettling comparison.

"I've already asked Iemitsu to investigate this matter." Nono explained, "According to this document, every single one of them had an injection before their personalities had changed."

"An injection? By whom?"

"We don't know," Nono's storm guardian, Coyote who was standing by his boss' right side replied. "Iemitsu said that there were several anonymous companies in charge of the vaccination but he cannot identify them for some reason."

"There are also reports of some having fevers not long after the injections too." The Ninth Vongola Sun Guardian, Brow Nie Jr added. "But our medical team cannot identify if the fever are coincidental or if they are a part of the injection's symptoms."

"We will need the Trident Shamal's help." Nono finally said, "The injection has proven to be difficult for our medical team and we will need all the help we can get. I want Visconti and Antonello to recruit the Trident Shamal."

"Yes sir!"

"Alright Boss."

"But Nono, what about the Decimo?" A voice suddenly asked.

'Ah Tsunayoshi-kun,' Nono mused to himself. "Do not worry, I already asked someone trustworthy enough to look after the Decimo. I had informed him of our situation so he should have received the letter by now."

"Yes sir."

"I already informed Xanxus and had the Varia on stand by." Nono declared. "The CEDEF will continue with their investigation as we speak and until we receive any new information, I want the rest of you to be observant of anyone who is suspicious. However, you must remember to not draw any attention upon yourselves or else we may be facing another problem. Do you all understand?"

"Yes Nono." Everyone within the room answered, their voice filled with a firm resolve.

"You are all dismissed now."

With no hesitation, everyone, except Coyote and Nono left in a meandering river of men in suits. Nono's muscle relaxed slightly and leaned back against his desk chair with a tired sigh.

"Nono are you alright? You should get some rest."

"I'm alright Coyote." Nono admitted, "I just hope Reborn has received the letter."

Hope you enjoy this chapter~

That was just the opening or prologue and after this scene the real story will be happening.

Nono would probably appear later in the story but it's not definite. I was planing on having the Varia to appear later and Iemitsu is most likely to not appear in this story besides being mentioned by someone. However this may change later since I'm still sorting out in just how my story is going to go.

This story is going to be focusing on Tsuna and his insecurities. So expect him to angst at least once in a while because he is going to suffer both emotionally and physically. (I know I am a sadist but it is every fan's duty to have their favorite character(s) suffer in anyway possible.)

To finish things off for now, here's the list of characters that is introduced in this chapter:

Antonello - An OC who might make a few appearance but otherwise he will not be relevant at all

Visconti - Nono's Cloud Guardian who might make a few appearance but is not going to be a major character

The other guardians are already introduced but might make an appearance later on.

Anyway, please review and tell me if I made any mistakes whether it's grammar or an information that is not canon and also tell me if I got any of the characters right.

Thanks for reading~
