Hey! This is my first Naruto fic, so sorry if it's not good. Itachi will probably be ooc in this story, but oh well. The beginning of the story is set in the past, when they are foutneed years old, but after the first chapter, then it will be set to when they are older. This story is when Itachi was younger, so this is before he destroyed his family and before he joined the Akasukie. The idea of them going to different worlds is from Kingdom Hearts, so I give them some credit. Read and review please! :3

Chapter 1: The Past

It was a beautiful day in the Wolf Kingdom. The sky was crystal clear, and the birds were singing. The civilians in the kingdom also seemed happier than normal. It was a happy day, because today was the day the princess was born.

It happened early that morning, when the queen gave birth to a beautiful baby girl, who was the princess. The civilians have been waiting for this day for months now, and so have the queen and king.

The king and queen were in their room, holding their heir to the throne. She had just now opened her eyes. They were just like her fathers. Dark brown.

"What should we name her?" Asked the king as he smiled at his baby girl.

The queen has been thinking about this question for a while now. They had picked many names, but none of them just seemed right. She tapped her finger on her chin. "How about Serenity?" Said the queen. "It means peace."

The king nodded his head. "That's a wonderful name." He said. "We'll call her Serenity."

Serenity was well cared for, and everyone loved her. Since she was the princess, she got everything she wanted, and she was spoiled, but she didn't act like she was.

As she got older, she looked more like her mother, and at the age of ten, you could tell her was royal. Her hair was brown and it toughed the middle of her back. Her brow-skimming bangs were blonde, which no one really understood, but they thought it was unique. Her eyes were dark brown, and they always glistened in the night sky.

Her parents have always taught her how to be a respectful princess, and how to rule a kingdom, but that's not what she wanted to do when she got older. Serenity would usually get herself into some kind of trouble, and her parents would always scold her because it wasn't princes like.

At the age of thirteen, she began to make decisions of her own. Most of them her parents didn't approve of though. They always thought she was going to be a good princess, and they always thought she was going to respect their wishes, but they were wrong. If anything, Serenity was more like a tomboy than any other girl in the kingdom.

She never wanted to be waited on hand and foot, and she never liked being treated differently than everyone else. She wanted to be a normal girl, and she has told her parents that before, but they keep telling her that she is a princess and that will never change.

Serenity was never able to go to school like normal kids, and she wondered what it was like. She would ask her parents, but they would always tell her that they didn't know to much about it either since they didn't go to school either. They home schooled her, so she didn't have very many friends. Actually, the only friend she had were some of the maids that she talked to, and her Australian Sheepdog, Sherbert.

One day, the king and queen punished Serenity for leaving the palace without asking for permission, and Serenity was tired of it. She didn't get very far, and she wasn't able tos ee much because the guards caught her in a matter of minutes. Why do I have to be stuck in this place, she thought, why can't I see the world behind the palace walls? She sighed as she thought about it.

She sat in her room looking out the window watching all the servants work on the garden. Serenity didn't understand why her parents didn't just tend to it themselves, but she knew they would never do that.

She sighed, and laid down looking up at the ceiling. She then turned her head and looked at the picture that stands on her nightstand. It was a picture of her and her parents standing in front of the fountain that was in front of the palace. She was eleven when the picture was taken. She missed those days. Her and her parents never argued then, and she never got into a lot of trouble then, but now at fourteen years old she was always in trouble by her parents.

The sound of a door opening finally came to Serenity's ears and she sat up and looked at her door. It hadn't moved. She thought it was weird. I must be hearing things, she thought. She was about to stand up and walk over to the door and look out of it, but something stopped her. Someone grabbed on to her and placed her back on the bed. She tired to scream, but the person was holding their hand over her mouth.

The person put his index finger on his mouth, indicating that she needs to be quiet. Serenity's eye's were wide with fear. She didn't understand how this person got into the palace without the guards knowing. She didn't recognize the person either.

The person slowly lifted his hand over Serenity's mouth and put it in his pocket. Serenity didn't move. She was to scared to do anything.

"So you say you want to see what the world is like behind the palace walls." Said the person.

Serenity nodded her head. "Yes, but how did you know?"

A chuckle escaped from the persons voice. "I know everything about you." The person said. "I know your thoughts, I know your desires, and I know your needs. And getting out of the palace is one of your desires. So, I've come to help you."

"But how? The guards are always on the look out for me, and if my parents found out that I left, they would most likely find me in no time, and I would be in even more trouble than I am now." Asked Serenity in confusion.

"Who ever said that this is the only world out there that you could see?"

"I don't understand. How can there be more than one world. It's impossible."

The person shook his head. "No, it's not impossible. There are many worlds out there that haven't even been discovered yet. If you want to escape this place, your only choice it to leave this world and go to another one."

"But how would I get to another world? And how would I know if this place is safe or not?"

"There's no way in knowing if a world is safe unless you go there. So, will you travel to another world, or will you just stay in this place and never be able to experience freedom?"

Serenity thought about it. It sounded like a good idea, but would she ever be able to come back? Would she ever be able to see her parents again? So many questions were running through Serenity's mind. She wanted to leave this place, and she wanted to be able to see other things, but she was scared. She has never been away from her home, and she wondered how she would be able to survive if she wasn't able to come back. She looked away from the person. Could she trust him?

"You may not trust me," Said the person. Serenity looked up at him. He said he knew her thought, but she didn't believe it until now. "but I do know what's best for you, and it's not good for a girl to be cooped up in a place for a long time. Especially a girl like you."

Serenity tilted her head in confusion. "What do you mean by that?"

"You need adventure. You need to see different things, and you need to be free. You're not the type of girl that just sits around and does nothing. No, you're the type of girl that is always up to no good, the type of girl to do what no one expects. And that's the type of girl that needs to travel to different worlds."

"Yeah, you're right." Said Serenity. "I do need to see other worlds. I need to get away from this place. So, I'll go to these other worlds, and experience real freedom." Confidence was evident in her voice as she talked.

An evil smiled crept on the person's face. "Excellent." He said. He walked closer to Serenity and pulled his hand out of his pocket. "Have this." He said handing her a small crystal. "It's called a shining crystal. This little crystal will take you to different worlds. But there's no telling which one you'll end up in. It just puts you in a random place."

Serenity looked at the crystal and then back at the mysterious person. She nodded her head. "Alright, but how do I use it?" She asked.

"All you have to do it throw it in a empty space. Then a portal will appear and then you walk into it."

"Well, that's simple enough." She said.

The person nodded. "Now, I'll leave you with that. Have a happy travel." The he vanished. His last statement sent a shiver down Serenity's spine, but she didn't think much of it, she was just happy that she would be able to leave.

Serenity wondered why that person had come. And she wondered why he came to her. She shrugged her shoulders. She remembered what he told her about using it. "Here goes nothing." She said as she threw the crystal.

When the portal appeared she took a deep breath and walked into it. She traveled through it, seeing weird things. It was like going through a parallel universe. Things were just floating around, and there were different colors all around her. Her eyes took in everything. This is weird, she thought. I never thought I would see any of these things.

A second later, a bright light came into view. Serenity shielded her eyes and when she uncovered them, she found herself in an area filled with trees. She looked around her. Where am I, she thought as she walked around.

She kept walking, and when she came to the boarder of trees she saw a wall, with a door in the middle if it. Must be a village or kingdom, or something, she thought.

She heard voices in the distance, and wondered where they were coming from. She walked closer to the sound, but something came spiraling by her face. She stopped head in her tracks and just stood there.

Serenity turned and looked to see what came at her. It was something silver, but she had never seen something like that before. She was scared. This must be one of those world that may be dangerous, she thought.

The voices were closer, but now she could only hear one. "I'll go get it." Said the voice.

A few minutes later, a boy, about the same age as Serenity appeared. They both looked at each other. The boy walked closer to Serenity, and she thought about moving, but her legs wouldn't let her. She was still shocked.

"Are you okay?" Asked the boy in a concerned voice. "I hope that kunai knife didn't hurt you to bad."

Serenity finally snapped back into reality. "A what?" She asked.

"A Kunai knife. You know, those things you use to cut things, and you use to fight with."

Serenity shook her head. "I'm sorry to say, but I don't know what that is."

The boy had a confused look on his face. "How can you not know what a kunai knife is? I mean you live in the village hidden in the leaves and everyone has those. Unless your parent's don't turst you with that kind of thing, but still, you should know what one is."

The village hidden in the leaves, thought Serenity, that must be what the place is called that I saw before. "Well, actually I don't come from here." She said.

"I thought so." Said the boy. "I've never seen you around before. But that still doesn't explain why you don't know what a kunai knife is."

"Well, where I'm from we don't have these kunai knives." Said Serenity.

"That's weird." Said the boy. "I thought everyone knew what they were." He shrugged his shoulders. "Anyway, since your not from here, where are you from?"

Serenity wondered if she should tell him where she really was from. Maybe he doesn't know about other worlds, she thought. "I come from the Wolf Kingdom." She answered.

"I've never heard of that place." He said. "So, what's your name?"

Serenity frowned a little at what he asked her. "You know it's not polite to ask someone their name if you haven't even introduced yourself." Her parents always told her that it was respectful to introduce yourself first before you ask someone their name.

The boy folded his arms. "Well excuse me. I didn't know you were suppose to introduce yourself. Anyway, I'm Itachi."

"And my name is Serenity."

"Serenity." Said Itachi. "I like that name. It's nice."

Serenity blushed a little and smiled. "Thanks." She said. "Your name's different. I've never heard anything like it."

"I'm the only one in my family that has this name." Said Itachi with a little laugh. Serenity laughed a little at that statement.

A voice was heard in the background. Itachi recognized the voice and sighed. "That's my brother." He said. "He's probably wondering why I'm taking so long to get back." He walked over to the kunai knife that was stuck on the tree and pulled it off. Serenity watched him. She thought he was interesting.

He walked back over to her. "I got to go now. Maybe I'll see you around." He said.

"Yeah, maybe." She said. Itachi walked away with a wave, and then he vanished in the trees.

"What took you so long?" Said Sasuke. It sounded more like a pout though.

"Sorry Sasuke." Said Itachi. "I got distracted by something."

"Well what could be more important than helping me train?"

"Look, I said I was sorry, so can we just get back to the lesson before it's time for us to get back home?"

Sasuke nodded his head with excitement. Itachi's thought kept going back to Serenity. He wondered what the Wolf Kingdom was, and he wondered why she was there. He had a feeling that she was different for some reason, and he wanted to find out. He wanted to meet her again, and he hoped that he would soon.

Serenity started wondering around again. She was happy. She liked the feeling of being free, and not having to stay in one place for a while.

The crystal started glowing, and she pulled it out of her pocket. She looked at it, and then a blinding light came. Just like the one before she landed in this world. When she light was gone, she found herself in her room again.

What happened, she thought, why did I end up in my room again? She sighed and laid back down on her bed. She put the crystal on her nightstand next to the picture. She closed her eyes, and fell asleep shortly after.

Her parents came into her room, and smiled when they saw that she was asleep. They didn't like to punish their daughter, but they knew they had to. If they didn't, then Serenity would surely get her way with everything. They were about to leave the room, but then the queens eyes caught the crystal on Serenity's nightstand. She was shocked.

"How did she get one of those?" She said in a low voice. She walked over to the crystal and picked it up. The King went to her and also looked at the crystal.

"No." He said. "It can't be."

"I think it is." Said the queen. "But I don't understand how she was able to get her hands on one of these."

"Do you think she's already traveled to another world?" Asked the King in a concerned voice. Fear shown in his eyes.

"There's no telling with Serenity. You know how she's always sticking her nose in places where it doesn't need to be." She paused for a minute. "But even if she hasn't, she doesn't need to have this."

The queen took the crystal and put it in her pocket. She looked back at Serenity, wondering again how she was able to get one of those crystal. They left the room shortly after.

Serenity woke later that evening and when she didn't see the crystal on the nightstand, she started to panic. She started looking around her room, hoping that she would find it. When she didn't, but slumped back down onto her bed. What am I going to do, she thought. The crystal is gone, and I don't know where it is.

Then she thought about it. She walked out of her room and down the stairs into the foyer where the fireplace was lit, and her dog and parents were sitting at. "Mother, father." She said as she walked beside them.

"Good evening Serenity." Said the king. "I hope you had a good nap. You seemed so peaceful while you were sleeping."

They did go in my room, thought Serenity. "I did," She said. She walked over to Sherbert and patted her on the head.

"Serenity, there is something me and your mother have to tell you." Said the king.

Serenity turned and looked at them. "Alright, what is it?" She asked.

"Me and your mother found something in your room that you have no business in having." Said the king in a stern voice.

"And what would that be?" She asked, he voice calm. She knew that if she wasn't calm, things would get worse for her.

"We found this." Said the queen as she pulled the crystal out of her pocket.

Serenity was shocked to see that she had it with her. She thought that they would have done something else with it. "How did you find that?" Asked Serenity.

"I should ask you the same thing Serenity." Said the queen. She didn't have a happy look on her face, and Serenity knew that she as in more trouble.

"Someone gave it to me. It's just a crystal, there's nothing special about it."

The queen laughed a little. "Nothing special?" She said. "If whoever gave this to was didn't tell you what this thing could do, which I doubt, then they have no idea what they gave you."

"They didn't tell me anything about it." Said Serenity, wondering what her mom knew about it.

"So, you're saying that this person didn't tell you anything about this and they just gave it to you for no reason?"

Serenity hesitated, which was a bad idea. "Yes."

The queen sighed. "Serenity, why do you constantly cause trouble?" She asked. "And why do you constantly lie to your father and I?"

"I'm not lying." Said Serenity, raising her voice a little. She was trying to convince her parents that someone did give it to her, but she knew she was lying about the person not telling her about it. "Someone really gave it to me."

"But how did they get in without the guards seeing this person?" Asked the king.

Serenity shrugged her shoulders. "How am I supposed to know? I was in my room the whole time and then someone came into the room and gave that to me."

"What was the person's name?" Asked the queen raising an eyebrow.

"I don't know." Said Serenity, knowing that she just lost the battle.

"Right, so the person just walked into the room without telling you who he was and then he just gave you the crystal and left."

Serenity nodded her head. The queen stared at Serenity, and Serenity stared at the queen. "You may go now." She said.

"Can I have the crystal back?"

"No." Said the queen. "Now go."

"But why not? What can one crystal do?"

"You know exactly what it can do Serenity." Said the queen, anger evident in her voice. "I'm not stupid Serenity, and neither are you. I know you went to another world with this crystal, and I know that if I gave it back to you, you would just do the same thing. Am I right?"

Serenity looked away. "Yes. You're right." She said. She walked passed them and headed up the steps without saying anything else to them.

"Oh, and Serenity." Said the queen. Serenity stopped, but she didn't look at her. "You'll never get this back, and you'll never go to another world as long as you live."

Serenity went back up the steps and the door to her room once she got there. This is so unfair, she thought. How did they know about the crystal, and how did they know that I went to another world? She lay on her bed and put her face into her pillow. She was angry with her parents, especially her mother. Serenity didn't understand why was so bad about going to other worlds. Sure, some may be dangerous, but as long as she had the crystal she would be able to escape. Right? That didn't matter to her now. What mattered to her was that he parents didn't even tell her about other worlds. If they knew about them, then doesn't she have a right to know about them too? She hated the fact that her parents kept things a secret with her, and she hated the fact that they never told her anything anymore. She wished things were back to the way they were before they started drifting away from her parents. Back to the time when she actually had fun in her life. And back to the time when things actually made sense in her life.

Serenity closed her eyes, thinking about the world she was able to see. She thought about Itachi. He was different to her. He didn't' laugh at her for not knowing something, and she was happy about that. She wanted to go back to that world, just to see him again. Even though she didn't know anything about him except his name, but she wanted to know more about him. But she doubted if she would even be able to go to another world again. Actually, she doubted if she would ever leave her parents sight again. Serenity slowly started to drift to sleep again, even though she wasn't that tired. Just weird things have happened to her that day, and she was tired of it all.

Thanks for reading! I know this didn't have a lot of Itachi in it, but I promise he will be in it a lot starting next chapter. Hope you liked it, and I hope you will continue reading it. Review please. Chapter 2 will be coming soon! :3
