Summary: "Tell this to the Boss of Vongola, Reborn, that I, Tsunayoshi Sawada cannot and will not be the Heir for them since they themselves had already killed him 12 years ago on the day that they sealed my brother and I. Tell this to Nonno that his reckless action of Sealing a Child who's an Active Sky without thinking whatsoever had come back to bite him in his ass. Why? Because I, Tsunayoshi Sawada, has only three years left to live. So, tell them to leave me the fuck alone and I will leave them alone. Oh, by the way, do tell Iemitsu that I said 'Congratulation for Killing your Own Sons with your own Hand!' Will you, Reborn?"

Pairing: R27 and Slightly ALL27

Warning: Iemitsu bashing!

Reborn had never thought that he would want to kill someone this badly before. Not even Skull had caused him to be this mad.

No, that's not right.

The World's Greatest Hitman was currently plotting a very bloody murder right now inside his mind. Who was he thinking off?

First would be the Vongola Information Network that they place over this place. Second would be the Bodyguards that a certain Idiota CEDEF head called the Best of the Best, and then finally, that bloody idiota himself! You must SAVE the BEST for Last, after all.

And oh boy, does a certain hitman wanted to save him for last.

Why, oh just why, was the World's Greatest Hitman thinking of such boring thing when he could just go and do it?

Why, indeed.

When Reborn gets back to Italy, that man was going to kisses the floor every second of his life. And why would that idiota kiss the floor when the floor hasn't done anything to warrant it?

Because, if there was one thing that Reborn hates the most, it was going into a situation blind or misinformed and mislead. Oh, the last time that a client had lied to him, mislead him, and oh cheated him over the contractor information? That client wasn't alive now.

And oh lord, the soon-to-be tutor had entered into Namimori not only blind, he went in like a deaf and bounded naive little child who has been lied to with the expectation level very high in return.

If this was a job or mission, he would have already been the ashes in his target's backyard.

Yes, he has information. Information and profiles for his soon-to-be-students, the mother, anyone that connected with the said student, the location, and setting that could be useful for him, people that are to be watched out for and what kind of place this place was.

He was also provided with an informational-contract, someone whom had been in this town and live here for a while now, that had first-hand experiences with dealing with the said student and the people here.

The World's Greatest Hitman gives a very grim smile that promise death and very painful(sadistic) moments to those people within his mind once he recalled the information about this student of his.

Information that was FALSE and has no similarity to the reality of what he had seen.

Nonno had asked him this favor to trains two certain twins, a Sawada Tsunayoshi and his younger brother, Sawada Kohinatsu. The older twin being better with academic while the younger better in sports and martial arts.

According to the information given, lied to, the eldest has a personality that was slightly timid, shy, quiet, average in his grades and doesn't have a friend at all, asides from said younger brother. His most noticeable traits were the spiky-gravity defying hair and his soft voice that was called the Voice of the Angel. He was the less favored to be the Decimo, due to his personality, delicate body and far too cute looks. Who would want to take him seriously if he was the Decimo? No one. Or so that idiota said.

The younger twin, on the other hand, was slightly taller, louder in both this action and voice. He was easily excitable, very childish when something went wrong, athletic in almost every sport, barely passing classes with low Cs, and have the most severe cases of Bro-Con, ever. The most noticeable traits were the fact that he already had his Flame Active and Manifested, which was sealed by Nonno due to that idiota's plead. He was more in favor of being the Decimo due to this reason, as well as the fact that he was physically stronger.

Oh, there's a bunch more information. Information that was personally noted by that Idiota, discussing other traits and weakness that both kids have.

Just thinking about that information caused Reborn's eyes to turn even darker and colder.

When Reborn got here three weeks earlier than planned, he decided to scout around the town and gather his own information before making contact with two boys.

Oh, how glad he was that he had done that.

What first made Reborn slightly comprehended wasn't the fact that this Town was slightly weird. It was the fact that the so-called First Rate Bodyguards was in fact, non-existence. Reborn check from high to low, from North to South, and yet, there was no bodyguard found at all. Instead, he found a nest of Spy that was actually going to sell information about the two twins to Vongola's enemy. Those spies? They are dead already.

And then, if that wasn't enough, Reborn has to watches as obvious kidnapper was targeting the two twins from the shadow, on their way home from school.

Reborn was seconds away from taking out his silenced gun when the so-called weaker-twin, Tsunayoshi, flicked something from his hand and hit the stalker/kidnapper right on their forehead, causing them to collapse without making any noise whatsoever.

Reborn blinked his eyes in both surprised and mid-interest.

He watches as Kohinatsu's eyes turned golden with a scowl on his face as he storms his way toward the collapsed body and kicked that man in the area that ALL males Don't want to be Kicked. And yet, the collapse kidnapper didn't even twitch.

Oh, he's still breathing, that much, Reborn can see clearly.

Reborn watches as the older twin just sigh out loud with a resigned sigh, before he took out a cell phone that looked to be obviously expensive and high-tech. Even more high-tech than his own, which, what the hell? Was Vongola Grade, okay?!

He watches as Tsunayoshi called someone, he watches as a group of delinquent-teens dragged the man away, he watches as Kohinatsu hugged Tsunayoshi tightly and looking like he was going to cry, he watches as Tsunayoshi smiled softly as he patted the younger twin over the head. He watches as the two boys went into the road that does not lead to their house but rather, toward the Namimori hospital, he watches as the two boys went into a room that was clearly their Mother's Room, he watches as the two boys tell story of how their days went by to a 'not-responsive' Nana. And finally, Reborn found his hand shaking in both rage and confusion.

What was this? What is with this situation?

The World's Greatest Hitman nearly saw red.

Taking a deep breath to calm his chaotic rage down, Reborn decided to regard this as a Rank SSS Mission. Objective: Find out what the fucking hell was going on and make sure the kids stay alive long enough for him to actually face them.

Three weeks passed since. And yet, Reborn still doesn't have the full picture of what happened.

The so-called First-Hand experienced contract was found dead years ago. The so-called Bodyguards from the First Rate Company was non-existence. He found nothing of what had taken place for Nana to be like that. What he found was a secretive spy group that had been going around spying on his soon-to-be-students. Oh, Reborn took great enjoyment in 'asking' about all the information that they had.

Apparently, seven years ago, ten assassins went after the boys at their school. This cause two students to get injured and five killed because they couldn't find the two twins. And yet, within seconds, those ten assassins drop death without any warning whatsoever. Their cause of death? Heart Failure and Brain death.

And then, five years ago, another group of assassin breaks into their house, causing critical injuries to Nana while the two boys were on a school field trips. The one that found Nana was Hibari Kyouya. Those assassins? They were found dead with one bullet holes in each other's brain, with the bullets being from their own guns.

All this thing happened and yet, Iemitsu never came back to see how his children and wife were doing?

Oh, Reborn now has another reason to hate that man if he wasn't already.

According to the newspaper, the town donates money to help the boys have their mother hospitalized. Right now, Nana was still in a coma with no sight of waking up. The doctors said that if after this year and Nana didn't wake up than it is better for them to unplugged her- to take her off life-support. At this rate, she won't die from her wounds but rather, from lack of food and activity. Due to her injuries, they can only feed her a little at a time and that, wasn't enough to sustain her for long.

Since then, everytime another assassin came, they were sent to the hospital under very painful and critical injuries, before being taken into custody by the Police, or now, the Disciplinary Committee.

Reborn recalled the scene from earlier and his brows slightly wrinkles. How many times had the two boys dealt with assassins already?

Remembering the situation from earlier, Reborn decided to watch the boys with an open mind.

After watching the two boys for another week, Reborn was FINALLY able to make new profiles.

Sawada Kohinatsu was not only athletic, passionate about pretty much everything and anything that his brother said it was good for him, he was also very serious when the situation called for it. Asides from that, he was also very cautious when dealing with people. He hides his true self behind laughers and keeps people at arm's length. The only person who he trusted his back to was his brother. While a good candidate for a leader, it would take Reborn sometimes and commitment for the boy to really shine.

As for Sawada Tsunayoshi, on the other hand. Honestly, Reborn wanted him to be the boss. The boy was kind to other but he wasn't stupid per sec.

Within the last 7 days of observing the older twin, Reborn notice that Tsunayoshi tried really hard got to not get attention from anyone. And yet, sometimes, he still slipped up and... oh god, Reborn could have sworn that he was bewitched. The boy was literally charisma walking. And when that happened, everyone in the class would turn daze and just... yeah, spend the rest of the class time looking at him. Even the damn teacher.

It was like there were a Sun and a Sky behind the boy.

However, weirdly enough, the next day, everyone had forgotten that Tsunayoshi had such a presence and ignored him again. It was like he wasn't there at all.

And, there was another thing.

Tsunayoshi reminded Reborn of a well trained, elite of the elite assassin. The silence elite kind of assassin.

The boy, while can be kind to other people, was really quiet and calm inside the classroom that everybody forgets about him really easily. He carried himself with a natural innate calmness that reminded Reborn of Fon, and with the movement that reminded Reborn of a graceful flower. A deadly graceful flower.

Counted all this, yeah, you can say that Reborn really wanted to make Tsunayoshi the Heir.

While the younger twin has the potential too, it pales in comparison to Tsunayoshi.

This belief was grounded in his mind after seeing how The Hibari Kyoya actually sleeping on his lapses like a little kid or a cat, with a small smile on his lips.

... Reborn really wanted to take a picture of this and send it to Fon but he refrained since he knew that such action will cause Tsuna to be alert.

Reborn sigh to himself. If only he can continue observing Tsunayoshi some more. He can't since he's here on a mission, not a vocation.

Tched, this is really annoying.

Just wait till I have sometimes, I will give that idiota a good beating and a lesson as to why no one lied to me.

Reborn told himself as he rings the doorbell to the twins' house.

The door open, and Reborn resist the urge to take out his gun to prank the boys like how he did it to Dino. This was going to be a long mission.

"Chaos. I am Reborn, the home tutor,"

Starring into one pair of surprised eyes and one pair of glaring eyes, Reborn steeled himself. He has a feeling that he was going to need a lot of alcohol or a very strong cup of espresso. And he was right when Tsunayoshi just smile softly and said, "So, you finally decided to show yourself?"

... Fuck. Where's my espresso?
