Prologue

Tsunayoshi Sawada was a normal person. He was perfectly below average. From looks to classes, except mathematics and science. He was 'Dame-Tsuna' of Namimori Middle School, who has a lot of bullies since Primary School, even now in Middle School, some few acquaintances here and there, living his life. That was before the Sun Arcobaleno Reborn came to tortu-tutor him. Reborn announced to him, that he will be the Tenth generation boss of Vongola, as the other candidates were dead and he was related to the First generation boss. Tsuna couldn't believe that, how could he when it was coming from a baby, an infant.

Reborn as Tsuna's tutor stayed in his house and follow him almost everywhere, from school to the shopping district, everywhere he went. A lot of things happened, great and dangerous stuffs, his experience with the dying will bullet. His confession to Kyoko Sasagawa in his boxers. Saving and befriending with the hot Italian punk, Hayato Gokodera, who actually came to kill him. Preventing Takeshi Yamamoto from jumping from the roof. Meeting a cosplay loving, Haru Muira. And a bunch of assassins staying in his house. And thus, making them his friends.

It didn't stop from there; there was the Kokoyu gang, and their leader Mukuro Rokudo, who were all escapee from the Vincide Prison. They started attacking students from Namimori, pissing Kyoya Hibari, who was heavily injured. Tsuna and his group went to face with Kokoyu. And in Tsuna and Mukuro, Tsuna was able to use Hyper-Dying-Will Mode, strengthen his intuition and win the fight. And the Vincide came to retrieve those prisoners.

Then, the arrival of the Elite Independent Assassination Squad of Vongola, the Varia. Challenging Tsuna to fight for the rings. And the Ring Conflict had begun. The battle of each chosen candidates starting from the guardians of Sun, then Lightning, Storm, Rain, Mist, Cloud, and finally the Sky. The revelation of Xanxus' identity. Mastering the Zero Point Breakthrough First Edition and Custom.

There was also that Byakuran incident. In which, Tsuna, ten years in the future, died in the hands of Millefiore, leaded by Byakuran and his right-hand man, Irie Shoichi. And the present Tsuna was sent 9 years and 10 months in the future instead of ten years to prevent Byakuran from controlling the world. Tsuna and his guardians, who were sent one by one, fought once more. The infiltration of Millefiore's Melone Base begun, Irie Shoichi's real intentions, the Arcobaleno Trials, the 6 Real Funeral Wreath of Millefiore, the Sky Arcobaleno Uni, Inheritance Test of Vongola, and the final battle between Millefiore and Vongola, with the assistance of Varia in the future time and Giglio Nero Famiglia. Uni, with Gamma, sacrifice their life to seal the mare ring and return everything to normal. That snapped Tsuna and used all his flames for a single attack and won. The Arcobaleno were revived as well as those who died in the hands of Byakuran. Thus, the young Vongolas were able to return to the present.

_...oooooo00000OOOOXOOOO00000oooooo…._

And after that incident, when things were supposed to return to normal, Reborn started his Spartan-like Training. Every day after or before school, Reborn would always find way/ways to train Tsuna. Stating it will help him when he becomes the Vongola Decimo.

And during their training Reborn notice something from Tsuna. His movements were at some point would be very accurate and at some point average, but it doesn't drop. As if Tsuna was holding back. It wasn't just Reborn, everyone in his Famiglia could see it. Tsuna's sluggish growth suddenly becomes rapid, it was way too fast. His stamina and strength was nearly Yamamoto and Ryohie level. Sure, he was tutored by Reborn, but there was something else. They decided to confront Tsuna about it.

"Tsuna, what's wrong with you?" Reborn asked Tsuna, they were training together with Tsuna's guardians (even Hibari) some adult (Biachi, Shamal, Dino, And Romario) and was an adults (Colonello), in Namimori forest. All of them stop when they heard Reborn question.

"What do you mean, Reborn?" Tsuna turn to face the Sun Arcobaleno.

Sigh "Your strength, stamina, they just suddenly boost up." The fedora hitman look at him, "I could say some of it is from my training. And it not only me." The hitman motion his head towards the others behind him. "We all notice."

Upon the gesture of his tutor, Tsuna saw his famiglia's face. They were filled with worry.

"So?"

Turning his attention towards his tutor, "The mafia-" Before the hitman could retort, Tsuna continues, "-it's getting on me."

Silence.

They were trying to understand what he meant by that.

Mafia getting on him.

"What do you mean?" It was Dino who asked. He could understand, how could the mafia affect his little brother so much that it triggered his growth.

"Reborn, aside from being the descendant of Primo." Tsuna asked, his voice was low but could hear. "Why didn't Ninth hesitate choosing me as candidate when he has three son?"

"Why are you asking that, Tsuna?" Reborn look at Tsuna, who look back at him. "It was said by the Ninth something about you possessing strong Sky flame which is true. Why are you brought this up?"

"You wanted to know, right? My flames would become stronger with stronger resolution." Tsuna was a bit shaking, "but when I was angry or pissed I lost control of them, just like when Uni died."

"But Tsuna what happened there was-" Dino was trying to comfort Tsuna, but was stop by Reborn.

"You couldn't control them."Reborn voice was filled with disbelief. "And how can you say this? You must have a perfectly long patience to-" he look at Tsuna, "That would explain part of it, but the part you can't control your flames."

"During the Ring Conflict the Ninth showed me a memory when I was young. Those times my flames were coming out every time I cry too much. The Ninth said something I can't remember about flames. And he used his flames on me." Tsuna sat on the rocks, "I don't know why, I rarely get angry, not to mention piss, so I don't know. There were several times that happened."

"The fight between you and Byakuran."

"What do you mean, Reborn-san?" It was Gokudera, he was worried for his boss/friend. And it wasn't just him, everyone was worried for the brunet.

"That barrier created by Tsuna's , Byakuran's and Uni's flames was strong that none of you was able to destroy it, but merely making a small crack despite that. I know all of you were weak that time but so was Tsuna." He eyes examine Tsuna, "Not to mention he was not only able to defeat Byakuran but was also able to destroy the barrier."

"You wasn't able to feel the pressure since the was only a small crack. But for me was inside the pressure was unbearable." Tsuna look over his friends. "I'm sorry. That time I was focusing on killing Byakuran I let a piece of my restrain slip. And if not because that barrier who would have been-"

"It's fine. We're fine. That's all there is." Dino assured Tsuna. He can't stand to see Tsuna like this. For him Tsuna was not only his precious little brother but also the 'Good Guy' in the Mafia. The very same person, which made the Mafia much more bearable, Vongola or not, Dino would do everything for Tsuna.

"It wasn't your fault, Jyuudaime. You only want to protect Uni." Tsuna believe in Hayato, Tsuna trusted him. After being saved by Tsuna, Hayato pledge his loyalty to him, he knew he was not alone. He could always return to Tsuna's side. He would do anything to prevent Tsuna from harm. Tsuna was his first friend.

"That's right, Tsuna." Tsuna was his first real friend, he was the one who saw Takeshi, beneath those fake smiles, the real him. The moment Tsuna save him from committing suicide, he knows tsuna will always be there for him. And despite the danger Tsuna brings with him, Takeshi will also be there for Tsuna and follow his leadership.

"Sawada stop thinking like that. You're an extreme good person to everyone." Ryohie view Tsuna as the little brother he has to protect. Even though, Tsuna is much more capable and reliable than him. His respect Tsuna and follow him regardless of the difficulty he'll face.

"Boss is too kind to do that." To Chrome, Tsuna was the first person who accepted her into the famiglia, the very same person who made her feel what it's like to have a family. She cares for Tsuna as much as he cares for her.

The solitary prefect, who accepts no one and respects no one, has grown to respect the young Don. The boy was the prefect's entertainment, since the boy was an omnivore (well Tsuna is dangerous but he pretends to be weak), and not to mention that the prefect was attach emotionally to the young Don (Not Romantically!), for accepting him despite of what he does. Well, that applies to all of them.

The adults obviously feels the same, they see not only Tsuna as the Vongola Decimo but also as himself. The obliviousness, recklessness, and pureness of the young boy despite being a trouble magnet, brought light to their dark world as Mafioso. For them Tsuna is their younger brother, junior, friend and of course a family.

After crying for a while, Tsuna finally calmed down, as his cry turned into soft sobs.

"Thank you everyone." Tsuna mumbled as he lost conscious, and fell. Luckily Reborn was there to catch him(his head) and prevent any injury.

"Let's keep what we heard here. Not a single thing must be mention again." Reborn neutrally, but they know better than going against the order of the World's Greatest Hitman. "This will be all for today. We'll schedule another session next week. Gokudera carry Tsuna."

As Reborn finished saying that, he head home. The Guardians exchange looks and did as Reborn said. They headed to Tsuna's home.

Today was so eventful, they needed time to think of this matter.

But one thing is certain; they'll never let their boss suffer alone.

They'll become stronger, so Tsuna doesn't have to worry about them too much.

They know Tsuna, just as Tsuna knows them, and they know (it's obvious) that Tsuna is slowly becoming a Mafioso, even though he is not aware of it, they all see it.

Even though Tsuna doesn't want the position, the ring was still in his proprietorship.

Even though he would deny the role furiously, a part of Tsuna was already starting to accept the role as the Vongola heir.

And it's happening soon.

This is my first story XD
