And yes, I'm working on another fanfic. This one is blatantly TsunaxOC but I promise to make the pairing as realistic as I can since no one, including me, wants to read a story on instant love and mary-sueness *shudder*. So, the series will start off pretty slow but will get pretty dramatic later on, I can promise you that.

Disclaimer: I don't own Katekyo Hitman Reborn. Only the main character of this story as well as any other OCs who support the main character.

Prologue

Yuuki's fingers trembled as she clumsily worked to unclasp the metal locks, her hands slipping several times to undo them in her haste to open up the leather case and see what was inside.

Days she had stared at the case, curiosity eating her from within. By the shape of it, she knew it was a musical instrument.

For some reason, Yuuki couldn't bring herself to open it and had left it untouched on her neat wooden desk. She didn't know why she didn't want to see what was in it; was she scared? Yuuki had no idea. But whenever she wasn't doing anything she would always find her stare wandering towards the leather case or her thoughts drifting towards it if she wasn't in her room.

Eventually her curiosity of wanting to open the case got the better of her which was why she was finally forcing herself to look inside the case.

Gripping the sides of the lid, she took a deep breath and forced herself to pry apart the case.

Yuuki could only stare in awe at what had laid inside the entire time.

Staring up at her, nestled in dark blue velvet, was a violin. A well taken care of violin as its polished wood gleamed up at her imploringly. When she picked up the instrument, the girl blinked at just how natural and light it felt within her hands. Was this violin hers?

That was a stupid question. Of course it was hers. Why on earth would it be in her room otherwise?

But it was the first thing in weeks that had felt nostalgic. Everything else was she saw or touched just felt plain awkward.

She picked up the bow that had been lying right next to its respectful place by the violin. She tuned the instrument before positioning it on her shoulder, resting her jaw on the chin rest. While Yuuki held on to the bow with her right hand, she contemplated on what piece she should play.

After several minutes had passed, Yuuki decided that thinking about it was getting her nowhere so she should just go with what she had been following the entire time to get her through the days: her instincts.

The first several times she had slid the bow on the tight strings of the instrument she wasn't playing anything in specific. Not that she expected herself to.

But the more she played, the longer the notes became until she was playing something that resembled actual music. It was an upbeat catchy tune, yet the story it told was in contradiction to that.

The piece she was playing told a story about two people. It was a story about love and loyalty. A story so intertwined between those two that one of them was willing to kill the person they had fallen in love with for the sake of that other person. And even then when a crowd came to kill the one who gave the orders, the one who remained loyal switched places with that person and took their place in the execution with no one the wiser to the switch.

They were siblings separated during childhood to perform their duties.

A princess and her servant.

Sister and brother.

Twins of evil.

When the song came to an end Yuuki heard someone knocking at the door.

"Oh, uh, come in!" She called, quickly placing the violin and the bow back into the case and slamming the lid shut just as a woman entered the room.

"Was that you playing?" The woman asked, looking at Yuuki curiously.

"Yes." Yuuki nodded, already feeling uncomfortable under the woman's curious and hopeful gaze.

She and the woman resembled each other strongly in appearance with a few differences here and there. It was like staring in a mirror, except that Yuuki had long auburn hair that came down to the middle of her back while the woman's hair was a light chocolate colour and shoulder length. They had the same hazel eyes, though Yuuki's were a little more greener.

But that shouldn't have been surprising considering that the woman was her mother.

"Did you... remember that song?"

And Yuuki was forced to shake her head and say no because she hadn't remembered the song at all; she had just allowed her body to move on it's own.

Her mother's hopeful expression faltered for a second but since Yuuki had been expecting it, she hadn't missed that brief second of sadness before the woman forced herself to smile at her again.

"Alright then. Dinner will be ready in half an hour, so come down by then alright?"

Yuuki nodded and the woman left the room.

Once she was gone, the girl let out a long breath that she hadn't realized she had been holding the entire time. As usual, whenever she spoke to someone, the conversation had ended on an awkward note that left an unpleasant taste afterwards.

She went to the bathroom and peered at herself in the mirror. Gazing back at her was the face of a girl who had resembled the woman who came into the room earlier.

Her room.

She stretched one of her cheeks.

She was staring at her reflection.

Yuuki reached out and touched the mirror, the reflection doing the same. No matter how many times she did this, it was like staring into the face of a stranger. She knew that the mirror never lied and that the girl with auburn hair and hazel eyes was her, but still...

...it didn't feel right.

Not wanting to stare at her reflection any longer she went back into the bedroom and lay on her bed to stare up at the ceiling, recalling what had caused this awkward tension between her and those she knew.

The doctors told her that she had amnesia that had been brought on by the physical trauma of being run down by the car, even though it had slowed down enough as not to cause any significant injuries.

But it was enough to put her in a coma for two weeks.

0000

When Yuuki finally woken up, she discovered that the only thing she remembered was her name: Yuuki Kobayashi. All of Yuuki's memories of her family and past before she had woken up in the hospital had completely vanished.

She was capable of taking care of herself and was able to function normally in society, but those she used to know before were now complete strangers to her and that the surroundings she was normally accustomed to had become unfamiliar.

It was worrying but the doctors assured her parents that her memories would come in due time. It wasn't very surprising that she had amnesia since she did hit her head upon impact with the pavement.

That had been five months ago and still Yuuki remembered nothing.

She knew that it hurt her parents when she still greeted them as if they were merely acquaintances getting used to each other, but what could she do about it? It wasn't easy for her to treat the very people she had supposedly known for her entire life like that, but that was how she felt towards them even if it made things uncomfortable.

They visited another doctor when it became clear that she wasn't going to remember anything any time soon and he came up with a very plausible theory as to why her memories weren't returning to her despite her head having long healed.

"It's possible that there is a psychological block within her mind preventing her from regaining her memories. What was she like before the accident?"

And to her surprise, it sounded as if Yuuki had been going through some sort of depression.

She went to school and earned good grades, but hardly interacted with any of the students at her school much less had any friends. And when would come home, she would always lock herself in her room until it was dinner time. During meals, she was very solemn and wouldn't say anything unless she was asked a direct question that concerned.

Interestingly enough, her older sister and brother as well as her parents said that it had been a very long time since anyone had seen her smile.

This made Yuuki wonder what was going on in her life before the accident and if her memory loss was actually a good thing disguised as being bad, but she didn't voice this out loud.

She glanced over at the alarm clock by her bedside table and saw that fifteen minutes had passed. That meant she had fifteen more minutes before dinner was ready. Pushing herself off the bed, Yuuki decided to go down earlier since she had been stuck in her room all day anyways. Just as she was creeping down the stairs, she heard voices talking.

Instantly the girl knew that whoever was in the kitchen was talking about her.

Walking down the steps as quietly as she could, Yuuki used the carpet padded stairs to her advantage. They always talked about her whenever she was in her room or when she was out, so even though she knew it was wrong, she would listen into their conversations when she got the chance. Her family for some reason seemed reluctant to talk to her about what kind of person she was before the accident, as if they were afraid of something.

"...heard your sister playing the violin!"

That was her mother.

"Did she remember how to play the violin or did it come to her through instinct like everything else did?"

That would be her older sister Maiko, or Mai, as everyone called her.

There was a pause before their mother let out a reluctant sigh and answered that she it was as Maiko had said.

"It's been nearly half a year!" A male voice growled angrily and Yuuki instantly recognized the male voice amongst females to belong to her older brother Kenshin. He was the one who was the most angry about Yuuki's current condition and was also the one who was the most hurt by her inability to recognize them.

"Be patient." Yuuki could picture Mai rolling her eyes at him. "It takes years for some amnesiac people to recover their memories. Just be grateful there wasn't any permanent brain damage."

Out of the entire family right now, it was her sister who she was most at ease and got along with the most.

"Enough you two!" Their mother scolded them. She didn't like it when the kids quarreled. "There's nothing we can do. You know what the doctor said."

The last specialist they had visited said that there was a chance that Yuuki would never recover her past memories. That didn't sit well with her family, so he suggested a variety of things that might help trigger something, but in the end only time would tell.

"So have you told her?"

The eavesdropper leaned in closer. They must have had some family meeting or something prior to this conversation without her because she had no idea what they were talking about.

"No, not yet." A pause. "I was planning on telling her about it when your father comes home."

"I don't see how having her live in Namimori again is going to help her. The bastard who hurt her still lives there, last I checked." Yuuki's ears perked. This wasn't the first time she had heard Kenshin refer to the 'bastard' who lived in their old town in Namimori, Japan but when she asked him about it he would always clamp his mouth shut, gritting his teeth.

"Kenshin!" Uh-oh. Looked like her brother was in for it now; their mother sounded angry. "I've told you time and time again not to call him that!"

"What the hell else am I supposed to call him?" Kenshin sounded angry as well. "He did more than just hurt Yuuki's feelings; he DESTROYED her! You remember what her face looked like before we moved to the States! It's because of him she was practically a basket case for the last three years!"

Realizing that things were about to get ugly really fast, Yuuki took this opportunity to sneak back up the stairs and avoid being caught listening into what was a private conversation.

Besides, her latest eavesdropping excursion had left her with even more questions that needed answering. Analyzing her brother's words, someone, a boy, had hurt her emotionally and it had been pretty bad.

"It's possible that there is a psychological block within her mind preventing her from regaining her memories."

Was the person three years ago who had hurt her the reason for her state of mind now?

And I'm done! Hope you like this, even though it only took me two days to write. I want you to tell me what you think of the first chapter, even though it's a bit slow right now. Do any of your recognize the song that Yuuki was playing on the violin? Tell me in your reviews!

I'll give you a hint though: Vocaloid.

Just so you know, Yuuki's violin skills makes very important statements through out the story. You'll see.

Don't forget to review!
