Summary: Reborn watched his new student and couldn't feel but be infatuated by his student's action. It was time to burn those useless documents about his student. Sawada Tsunayoshi is more than he seems. And he's going to find out all of the mystery of his student!

Black-chan: Woah! It's already chapter 4? That was fast for me! Anyway, thanks for Flickering Hope, Psycho-Pacgirl, and painxsmile for reviewing this! I really appreciate it~!

Warning: Curses and crappy chapter. This is somehow going to be a boring chapter…

The Tale of a Father

It was cold. Very cold.

The boy in a water prison couldn't escape. He knew that now. But that didn't mean he regret what he had done.

So what if he killed an entire famiglia? So what if he did it again? So what if he controlled someone to do it for him?

Those famiglia was better off burn to pieces anyway!

But of course, it didn't mean he liked staying in this water prison. He hated everything here –well, maybe except for one.

The brunette that kept a mind link to him, the brunette that kept on visiting him, the brunette that was too bright for this place, and the brunette that slowly came to cry out for freedom.

He wouldn't mind him at all for he had saved him, the Fallen Illusionist, to fall lower.

Tsuna groaned, stretching his arms –he really had a nice dream, thanks to his so-called big brother.

He opened his left eye to be used to the sunlight before his right eyes followed in suit.

He scanned his surroundings. Simple room and simple decorations but peaceful atmosphere.

His room. He was in his room but the question was who carried him?

He was sure his self-proclaimed sisters couldn't have done it since well… They just couldn't.

The door opened and Kyoko came in. "Oh, you're awake?" she questioned the obvious answer and smiled gently. "You should have said so. And don't get up yet."

The last words were voiced out with an unmistakable threat, making the boy nodded with a sweat-drop.

"So who carried me?"

The small male couldn't help but ask. Though, he wondered if it was a good thing since his so-called sister was practically sparkling in delight at the question.

"Oh, Tsu-chan, it's so romantic!" she exclaimed dreamily. "Your knight-in-black-armor pulled you into a tight embrace and carried you to your room bridal style~"

"What?" the boy blinked in confusion and tilted head cutely. "Knight-in-black-armor?"

"What Kyoko means is that since there is an attack to your unconscious state, Ryohei stayed back to fight off the attackers and Kyoko asked Hibari-san to carry you bridal style to your house which he did," Hana, who just came from outside, explained with a really dark aura at her words.

"Attackers?" Tsuna thought in distress. It had been a while since he was targeted. But then, he double took as he thought about the other statement.

"H-h-hibari-san d-did w-what?!" he shouted, his face red in embarrassment.

Before anyone could say anything, an unfamiliar voice interrupted their peace –or for Tsuna, one of his hellish embarrassing moment

"Well, aren't you lucky, Dame-Tsuna?" a baby in suit inquired, smirking at the redness of the only male's face.

'Don't you mean unlucky?' the boy did a comeback in his mind and widened his eyes when he realized something.

"What are you doing here?!" he pointed at the baby who shrugged.

"Didn't I tell you? I'm Reborn, your home tutor starting today," Reborn simply answered and the brunette couldn't help but feel the so-called tutor was hiding something deeper because his two proclaimed sisters were here.

"I thought it was all a dream," Tsuna almost groaned at it being not a dream. It meant more trouble to him and his secrets.

"Well, –" Hana started, making the two males stare at her and the other girl.

"–we'll be going now!" Kyoko finished, waving a goodbye. "Take care, Tsu-chan!"

They went home, leaving the two males to talk it out.

"So you're really my tutor?" Tsuna asked, breaking the silence that surrounded them. He still couldn't believe the Sun Arcobaleno/Strongest Hitman was in fact now his tutor.

"Actually, I'm a hitman sent to train you to be a mafia boss," Reborn replied simply, watching his student like hawk for any unusual reaction.

The brunette blinked and blinked before he finally understood what he had said.

"HIE! Mafia boss?! Are you kidding me?!"

Of course, the small boy knew the baby wouldn't be joking at this kind of questions but he was really surprised. He never heard of that and he sure no one in his family was involved in mafia families.

His mother was just an illusionist who didn't tie herself to any family so her mother was out of the question.

And he was sure he never had a father. Well, he couldn't remember anyway.

Though, it would be confusing if he had a father who was in a mafia family. If it was true, why wasn't he here to protect them?

Tsuna was again not oblivious or stupid. He knew the things that would happen if he was the son of someone in a high position to any famiglia to the point he was a heir.

But that didn't mean his father –if he had one–should visit his own son once in a while.

Plus a father was supposed to be there and protect his family, right?

And even if the man tried very hard to hide his family, it wouldn't do any good.

Someday, assassins and hitmans –and even spies and traitors–could come any moment and attack the family and said family wouldn't survive since they weren't told by the father or anyone who was in a mafia family.

He would have just wasted the years sent without being there for the son for nothing.

And the soon-to-be-mafia-boss-even-if-unwilling was sure they would have a rocky relationship.

The son wouldn't love the father but was rather tolerating the man since they were in a pitch situation. The son might not even know the father!

Also, the son wouldn't know the real love of a father.

Tsuna narrowed his eyes at that. Why did it seem so...

'Real?' the male dared ask himself. 'As if it was happening to me…'

He shook her head and slightly became hesitant and uncertain. 'But that couldn't be the case, right?' he argued back to himself, not knowing his eyes grew sad and dim.

'I don't remember a father and I don't even need one, right?'

Reborn watched his student closely. He was not surprised by the shout –though, he was suspicious about his student not screaming about the being hitman part.

But his silence and thinking through everything he said was suspicious to the arcobaleno. He had known the other as someone not the brightest and not knowledgeable to extent.

And in the first place, the baby wanted to ask about what happened in the school gym.

How could bypass Dying Will Mode and went straight to Hyper Dying Will Mode with uncontrollable sky flames?

It had been bugging him to the point where he had first asked his student's friends about it and them denying they knew of the flames.

Keyword: denying.

He was not the one of the strongest hitman for nothing. And it didn't help that they were pretty calm when some assassins suddenly attack the unconscious boy.

The new male even protected his student and stayed behind to attack the assassins. The male was called "Ryohei" by the Hana girl and if he wasn't mistaking it, that boy was a third year so how could he be friends with Dame-Tsuna?

Though, Reborn could already know it was due to his younger sister which was coincidentally one of his student's best friends.

But then again, this made the baby go back to the starting line. 'How did Dame-Tsuna be friends with the two popular girls and one sempai?' he asked himself, knowing a headache was coming.

He was glad for a challenge but this not-knowing-stuff was getting on his nerves.

"I am not kidding. Do you want me to shoot you to prove my point?" the baby asked finally with his usual smirk and gun, hiding the fact he was annoyed at being oblivious to his student's secret. "I'm sent here so I can train you to be the Vongola Decimo."

Tsuna widened his eyes to that. "Vongola Decimo?" he mumbled with a hint of acknowledgement to the title, making the arcobaleno narrow his eyes.

"Vongola is a mafia family known for its bloodshed history but in truth, it was a famiglia which helps civilian against many wars and fights."

Reborn didn't know what possessed him to say this but he had a feeling it was a good since the boy froze at his words, seeming to not believe it.

An uncomfortable silence clouded them again but the supposed-to-be tutor was patient. He felt as if good things would happen if he was patient and perhaps, he was right about that.

"What about the other candidates?" his student asked slowly, his eyes shadowed by his bangs but it was okay for the hitman.

He was in a lead. This boy should not even ask or know about the other candidates, meaning he knew more than he credit himself to.

"They're all dead," Reborn answered simply, now wearing a smirk that caused his student to flinch visibly like he was in big trouble. "But how did you know about them, huh, Dame-Tsuna?"

And the smirk the sun arcobaleno wore grew wider at the obvious mistake his student did.

Tsuna froze at his question and even stared at him with wide fearful eyes.

Though, it seemed he noticed it and quickly returned back to normal.

But it was too late. Even if it's just a second or minute, it was all that Reborn need to confirm her suspicion about him being aware of the mafia.

He really would call a certain blonde idiot about this then report back to the Ninth.

If his student was aware and hiding it, it would cause some trouble for the hitman and he just knew it.

However…

Reborn stared at his student with a mischievous smirk playing on his mouth. 'Why don't I take this to the next level? I might even get some more answers out of him,' he thought.

And the hitman opened his mouth.

Tsuna was not stupid. He was just tired and was being careless.

But then again, a mistake was a mistake nonetheless so it didn't surprise him when the arcobaleno smirked at him like he found out something.

After all, he froze at what his so-called tutor asked and didn't answer. It really hit the mark as well.

"Dame-Tsuna –" he couldn't help but narrow his eyes at the name even if he intended to keep it so as to not attract trouble. "–do you know about the dying will flames at least?"

The answer was definitely "yes" he did knew better than anyone else but he'd be an idiot if he had said "yes" so of course, he opened his mouth and said –

"Yes."

He blinked at what he had said and even the other looked as if he was an idiot and somehow, he suddenly felt he really was.

"I mean no!" the brunette quickly denied after realization of his another mistakes and silently wondered why his mouth moved on his own.

But then, he knew the reason. He kept on thinking "yes" and "yes" so it was no wonder he had slipped a "yes" not a "no".

"So what do you know about it?" Reborn asked again, ignoring his denial and he cringed slightly at the question which was a bad thing again since he knew his tutor noticed.

"I-it i-is err… a flame of a dying person's will?" the young trainee replied nervously, sweating like bullets. It was somehow true if some people think about it but how was he…

"Where did you find the word?"

'He took the words out of my mind!' he screamed in his mind though he remained normal as could be outside and really thought of an answer. "I-internet?" again, he couldn't stop the stuttering. It was a habit he got whenever he was lying but since the hitman didn't know that, he could just do it as if it was the fake stuttering he did at school.

The baby seemed to twitch in annoyance and the brunette almost sighed in relief but managed to stop himself. He couldn't keep on making mistakes like that if he didn't want the other to know his secrets –even if he was never good at talking or hiding a secret.

Though, he never really intended to hide it. It was really just a little too much for him to say –and to a stranger no less.

He shook his head fast so that the arcobaleno couldn't see. 'This is not the time to think about that,' he thought firmly inside and asked curiously in the outside, "Why are you even asking something like that?"

It was true. He was really curious at that. He knew the other wouldn't ask something like that unless he had someone saw a dying will flames or if he knew about them himself.

'Wait a minute!' he narrowed his eyes, showing a ten hint of sky-orange and without thinking, he thought aloud, "What happened before I collapse? Why was I even unconscious?"

He heard a chuckle and moved his curious eyes at his new tutor who said simply, "Thought you never ask."

Tsuna pouted at that but waited for the other to elaborate patiently. The other seemed to be mocking him at not knowing.

"Do you know about this?" Reborn showed a weird looking bullet to him and he blinked in confusion before shaking his head. He had never seen that bullet before.

"This is a special bullet that makes the person shot by it enter a state where he cannot feel pain and unleash the hidden power inside of that person."

The illusionist-in-training stared in awe at the bullet and the explanation. But that still didn't explain why he had something to do with it.

He looked expectant at the baby.

"And that state is called Dying Will Mode. They also have flames in their head called Dying Will Flames."

Tsuna felt the temperature grew down and the tension tightened.

He looked fearful now as if he was afraid what he had in mind was true.

'Please no! I can't have! There must be a mistake! I –'

"I shot you with it and you bypassed this mode and just went straight to Hyper Dying Mode, a much calmer and stronger state."

The boy paled and felt his mouth go dry. 'Did I?'

"Your sky flames also went out of control," the tutor finished, waiting for any reaction from the small male.

'Shit…shit, shit, shit!' he gripped onto the edge of his t-shirt roughly as he remembered the fight, the bullet and other fight –and god forbid, him throwing the usual knifes hidden on his clothes at his sempai.

That was bad. Very bad.

"So I take it you remember?"

Tsuna stared at his tutor and nodded at that but still asked in a really convincing obliviousness, "What was that about? And what's with the flames?"

He didn't know if the other believed his acting but at least, they got out of that topic.

But then again, he had to endure a really boring explanation about everything he already knew.

The young male wondered if the baby was doing it on purpose, just to annoy the hell out of him but didn't voice it.

He just went along with it and when finished explaining, he turn to go outside, not wanting to mess up again in front of his tutor who most likely turn his life living hell that it already was.

Though, he stopped by the door to ask something that's been bugging him from the start.

"Who is my relative who is related to Vongola for me to be the next heir?"

Reborn sighed at the leaving back of his student. He had answered the last question his student had asked and wondered if it's a bad thing.

His student's reaction was concerning.

He could still feel the heat of anger steaming from the other's head.

"Was that Tsunayoshi?"

The baby watched as the brunette mother came to view with a slight strained smile and he could only nodded.

Something about the woman just left a nostalgic sensation in the hitman's heart and he wondered deeply if a certain female Sawada was someone he had met in one of his trips to Japan before.

"Well, I have to warn you about something since you are going to leave with us," Nana said simply and a little bluntly with an edge of seriousness.

Reborn listened with interest as the woman looked threatening and gloomy at the same time.

"Never talk about Iemitsu to Tsunayoshi… Because he…"

'Well, damn,' Reborn widened his eyes just a tiny bit as he listened to the wife's explanation. 'I did not see that.'

Tsuna couldn't believe his ears but he knew it was the truth.

And damn, did he hate the truth.

He was merely thinking too much when he got the idea about him having a freaking father that was stupid enough to think he got protect him and his mother by keeping them in the dark and not being there for years.

HE DID NOT WANT IT TO BE TRUE!

And fuck, why wasn't he even inform that he got an abandoning idiotic father who might have make him a heir to some big illegal work by his mother?!

That's just wrong in senses!

Then, the brunette stopped in track and narrowed his eyes. 'That sounds like…,' he said to himself, his sensitive ears acting up and detecting a familiar sound of a ball.

He moved towards the sound and was not surprise to see a certain baseball star practicing like hell.

'Yamamoto Takeshi,' he frowned in annoyance, remembering his previous dream about the said player and knowing full well what he was doing to himself. 'Practicing 'til his body drop. Pretty suicidal, if you ask me.'

'But…'

"Um," his shy whisper echoed to the park they were in and the black teen faced in surprise.

"D-dame-Tsuna?" Yamamoto asked wide-eyed and Tsuna would like to have a credit for not snapping at the taller student.

God, how he hated that name.

Though, back to the point, the younger male pointed at the injury of the other which was announced yesterday by some nosy classmates. "Isn't your arm injured?" he asked worriedly.

He would have wanted to smack himself for worrying about others but that was his attitude. He couldn't, even if his life depended on it, stopping himself for being worried –especially, if he knew the other.

Well, at least, he got his mind drifting to what his supposed tutor said.

"Haha, it's fine! I'm okay!"

The acting and fake cheerfulness made the brunette flinch and without thinking, he blunted out, "Please don't smile in my account."

There came a tense atmosphere, making the small boy groaned at his mistake again.

"Say, Tsuna, I seem to be failing in my baseball skills…," the tall teen stated seriously after a couple of minutes. "What do you think I should do?"

A fond smile found its way to Tsuna as he remembered some training sections he had before.

"It's useless. I'm not good enough for this," a younger version of himself wined loudly with frustrated tears, his hands red from practicing.

"Come on, Hikari. Just try again," a lookalike of himself with red eyes and taller height said cheerfully with a mischievous wink though there was a hint of concern.

His younger self pouted slightly at the nickname and punched the unsuspecting victim, causing him to lay on the ground in shock at the sudden attack. "Stop calling me that! My name's Tsuna, Nobody!"

The so-called "Nobody" got back up and smirked at him. "See? Told you! You can punch hard," he said, shocking the smaller teen at the rightness of what he had said and told him something Tsuna never forgot –even to this day.

"If I think I'm failing, I practice. If I practice, I listen to others," he quoted softly, an image of the smiling face of himself with just red eyes appearing in his mind.

He even shocked not only the other but himself. When was the last time, he got to talk to someone else –other than his proclaimed siblings–like they were friends?

"If I listen to someone, I won't commit suicide," he finished his speech, not moving his eyes from the taller male and smiled knowingly to the baseball player.

"I guess you're right!" Yamamoto exclaimed with a tiny bit shocked and truly some cheerfulness.

'But.'

Tsuna nodded nervously at the other and asked for an exit.

He walked ten feet away from the other and glanced back with a dark scowl, knowing he wouldn't hear his last words.

"You're still going to commit suicide, huh, Yamamoto-kun?"

TBC

Black-chan: Told you guys this will be boring… I needed some filler and this is about Tsuna and Reborn's conversation and Tsuna's and Yamamoto's encounter. You guys will probably know what's going to happen next.
