'Thoughts'

Twelve years ago two great tailed beasts were unleashed among the Hidden Leaf Village. The leader of the village, the Fourth Hokage, sacrificed his life to seal the Nine-Tailed Fox into the newborn, Naruto Uzumaki and the great Eleven-tailed Wolf into Naruto's twin sister newborn to protect the village. Orphaned by the attack, Naruto and Mika were shunned by the villagers, who out of fear and anger, viewed them as the monsters that were sealed inside of them. Though the Third Hokage outlawed speaking about anything related to the Tailed beasts, the children — taking their cues from their parents — inherited the same animosity towards Naruto and Mika.

However, Mika and Naruto still held their smiling faces when they got into trouble. Causing mischief as they did seemed to have made the villagers acknowledge them. The people spat hateful words and curses at them but at least they were being acknowledged.

Naruto Uzumaki is a hyperactive mischief maker who can't seem to stay out of trouble. He has blonde hair and blue eyes and wears an orange and blue jacket with a red circle swirled on the back. He loves Ichiraku ramen and pranks. One day, he vows to become the Hokage so that everyone will have to respect him.

Mika Uzumaki, however, is a little calmer and likes the rain and dogs. She still loves Ichiraku ramen like her brother but doesn't care for pranks. Instead, Mika loves to draw and paint things for a hobby. She has brown hair and blue eyes like her brother's and she wears a blue and green jacket with the same red circle on hers as Naruto's. One day, she vows to become the strongest kunochi in the world like Lady Tsunade and earn the respect of Konoha.

One day, Mika was wandering the streets of Konoha, trying to find a food stand. Since Naruto and Mika eat ramen most of the time, she figured that they need some fruits and vegetables in their diet as well. That, and vegetables are cheaper than 4 bowls of ramen a night between the two of them. Even if Naruto didn't like it, he'd eat the vegetables for his twin sister.

When she finally found a stand with vegetables on it, she went over to it and examined which ones she would want.

"Hey, you little brat! Get away from my stand!"

The keeper of the stand glared daggers at the twelve year old girl, "But sir," she tried to explain, "I have money to buy some-"

"Your money's no good here, brat! You and your brother should have died a long time ago!"

This hurt Mika but she wouldn't show it. She got angry, "Now listen, old man. I'm going to buy a vegetable and you are going to take the money. Got it?!"

The owner of the stand was about to argue when a man behind her spoke, "Hello there. Is there any trouble here?"

Mika turned to see a silver haired man with a blue mask over his face and a headband covering his left eye. He was a ninja, Mika could tell, and a Jounin at that!

The stand owner cursed again, "You're damn right there's trouble! This little bitch is trying to buy some of my vegetables!"

The man simply smiled, "Why not let her?"

"What?! Don't you know who this little hellion is?"

Mika stepped in again, "My name is Mika Uzumaki and all I want is to buy some food for me and my brother!"

The silver-haired man looked down at her and then the stand owner, "Tell you what, why don't I just buy the food she wants for her. Would you take my money?"

"Of course sir, it's just that-"

"What?"

The stand owner sighed, "Nothing. Fine. Pick out what you want, kid."

Mika lit up with joy and carefully picked out some onions, garlic and some asparagus.

The silver-haired man smiled under his mask and paid for the vegetables, "Have a good day, sir."

Then Mika pulled out her doggy wallet with the money in it and handed him the money that would pay him back. However, the man merely looked at her hand, "What are you doing?"

"I'm giving you back your money. Or is my money no good enough to you either?"

Silver hair just laughed, "Oh don't worry about paying me back, little one. It was a gift. Enjoy your food. Maybe I'll see you around."

The man was about to take off but Mika stopped him, "Wait! Can you tell me your name at least?"

The man turned back around and grinned, "My name is Kakashi Hatake, little one."

Mika smiled back, "My name is Mika Uzumaki. It's nice to meet you Kakashi. Thank you for the food. This will last me and my brother days!"

Kakashi then frowned. Usually, that amount of food should only last a day. There was nothing he could do about it though.

"How old are you, Mika?"

The question caught her off guard, "I'm twelve, sir."

"Shouldn't you be in school?" he was curious.

"Oh. Well I asked Iruka sensei if I could come down to the market real quick. I didn't want to bring my brother here because he will cause a scene. Iruka understands."

"Iruka, huh? Tell you what, how about I take you back myself?" he smiled under his mask again.

Mika nodded, "Okay. Sure."

When they reached the school, Mika grew a little uneasy as Iruka stomped out.

"Break is over Mika! Where have you been! You and Naruto always get into trouble!"

Mika went quiet but Kakashi placed a hand on Mika's head, "She was with me, Iruka. A stand owner at the market wouldn't let her buy any food so I figured I'd do a little charity."

Mika was a little angry. Charity?!

Mika growled, "I don't need charity. I can defend for myself. I offered you money and you shunned it. Just like everyone else does me."

The two adults felt the mood and sighed. Iruka came over to Mika, "Thanks for bringing her back, Kakashi. I'll take her back to class now."

Kakashi waved good-bye to Iruka but lingered a little as he watched the sad girl go back to class.

When Mika got back into the class room, Naruto was in the front of the room all tied up and sulking.

'What did he get into now?' she thought.

Mika rolled her eyes and sighed, stalking back over to her seat. It was a normal day as always but this time Iruka was giving them a surprise test.

Because of Naruto they had to create two clones. Once again, Naruto failed. However, Mika, not wanting to take a bad grade, passed the test and created two clones. Everyone was impressed except for Naruto.

After classes, Naruto went over by the swing and sat there by himself. Mika watched with pain as the other students left with their parents, talking joyfully about their day. Mika looked back over to her brother and walked up to him, sitting in the grass beside him in silence with the bag of vegetables she had gotten today.

Silence passed for a few more minutes before Iruka finally came over to them, "Hey kids. You know, maybe I could treat you both to ramen tonight? What do you say?"

Both Mika and Naruto's faces lit up," Okay!"

They went to Ichiraku ramen bar and Iruka let them get one bowl each. There was silence again as they all ate their ramen in peace until Iruka spoke up, "I don't know why you two seem to get into trouble all of the time. Naruto, why would you do such a thing to the Hokages'? You do know who they were right?"

'What the hell did he do?'

"Of course I know who they are! To be Hokage, you have to be the best shinobi in the village!"

"Then why did you paint the Hokage's faces with graffiti?"

"YOU DID WHAT?!" Mika screamed at him and Naruto had the sense to cower.

"Hey don't worry sis! I cleaned it all up!"

Mika growled at her brother but Naruto answered Iruka's question, "Because some day that'll be me up there. One day I'll be Hokage and then everyone will have to accept me! Everyone in this village will have to stop disrespecting me and look up to me! Believe it!"

"Oh Naruto" Mika sighed.

Iruka seemed to have understood Naruto's messed up logic and answered in silence, not sure of what to say. Then Naruto spoke up again.

"By the way, Sensei? I have a favor to ask of you."

Iruka narrowed his eyes, "Is it another bowl of ramen?"

Mika giggled but Naruto shook his head, "It's . . .Your headband. I . . . Wanna try on your headband. Pretty please?"

Iruka was startled, "My what? Oh no, no way! A headband is the sign of a shinobi of the leaf village. You have to pass your exam tomorrow if you want one of these."

Naruto frowned and Mika cuffed the back of his head, "You dork."

"So that's why you took off your goggles." Iruka smirked.

Naruto smiled a little.

The next day was the exam day.

Again.

Mika and Naruto have taken the academy exams twice already. Naruto always took it first. It was always the same thing. They had to produce two shadow clones and a copy of Iruka sensei. Mika could have easily done it. It's just that her brother can't. And she didn't want to leave her brother behind. So if Naruto failed. Then she failed.

And once again, Naruto did fail.

So Mika did as well.

Iruka was so angry and it didn't help when Naruto used his stupid Sexy Jutsu over Iruka. It just pissed off the guy even more so.

However, Mizuki, another chunin who teaches in the academy tried to let Iruka give them the headbands. Naruto did after all manage to create one clone.

"No. The task was to create two clones. Naruto only created one and a horrible one at that. However, Mika, I'm a little confused about you. Yesterday you did just fine. Try it again like you did yesterday or you both will fail."

Mika didn't know what to do. Iruka seemed to have found out that Mika was only failing to be with Naruto. She glanced at her brother, how nodded, trying to smile. Mika took that as a sign that it was okay.

So she created the clones perfectly and received her shinobi headband. She was so proud of herself. She had finally passed. However, Naruto didn't look so happy and went off on his own.

She was going to go after him when a hand stopped her. Mika turned to see Kiba Inuzuka smiling at her, "Hey! Have you always been able to do that?"

The boy had a puppy with him that she knew was Akamaru. Kiba had brown hair and brown eyes. He also had strangely long and sharp canine teeth similar to a dog's. The Inuzuka clan, a clan that are known for their use of canines as fighting companions and are easily identified by the distinctive red fang markings on their cheeks.

Mika loved dogs, so she instantly liked Kiba and Akamaru. However, he had never really spoken to her until now.

"Y-yes." She said.

Kiba laughed, "Hey now, no stuttering or you'll sound just like that Hinata Hyuga girl."

Mika blushed, "Sorry. It's just that you've never talked to me before."

Kiba stopped laughed and smiled at her, "Well I guess that's because I thought you were just like your brother."

"What's that supposed to mean?!"

Kiba sweated, "Uh! Nothing horrible! Never mind! You're definitely not your brother. Umm. . . but the way you created those clones like that. . . if you could always do that then why didn't you before?"

Mika hesitated a little, "Well. . . uh. . ." she didn't know how to put it, "He's my brother, my twin and my only family. And family has to stick to together. I couldn't just leave him on his own. But now that Iruka has found out, I see no point in pretending anymore. Naruto will pass eventually."

Kiba was surprised at the girl's words, "Oh. I think I get it. Ummm, we get our teams tomorrow. I was wondering if maybe you'd like to come down to the Inuzuka clan home to celebrate? You could bring Naruto too I guess."

Now it was Mika's turn to be surprised, "Gee thanks and all. I'd love to but I'm going to have to say no for now Kiba. Naruto's pretty sad about not passing. He'll need my comfort. Sorry."

Kiba looked disappointed but smiled anyway, "Nah, it's okay. I get it. See you around then?"

Mika smiled, "See ya."

Akamaru barked softly and Mika laughed, "See you too, Akamaru."

She then turned to leave but noticed that she couldn't find Naruto anywhere.

Where could he be?

It was after midnight by the time she heard of anything.

Naruto came back to the apartment of theirs all beaten up, bloodied and bruised. She was about to scold him when she noticed something different.

"Naruto?"

Her brother laughed and cried at the same time, "I did it, Mika! I'm a shinobi now! I did it!"

Mika didn't know what had happened but she hugged her brother, squeezing him tightly, "I'm so proud of you! How did you do it?! What happened?!"

Naruto set his sister down and explained the whole story about how Mizuki had tricked him into taking the legendary scroll. But Naruto had learned how to make clones! He also told her how Iruka had saved his life and then he repaid the favor by kicking Mizuki's ass. Iruka had given Naruto his own headband that night.

However, something was bothering Naruto and Mika could feel it.

"Naruto what's wrong?"

"Sigh well Mizuki told me something. Something about us and why the villagers hate us so much, Mika."

Mika listened carefully, "Go on." She encouraged.

Naruto gulped and told her that they possessed tailed demon beast spirits inside of them.

"He said that I carried the Nine-tailed Fox demon and that you had the Eleven-tailed Wolf Demon. The Fourth Hokage had sealed the demons inside of us to protect the village. The Fox and Wolf demon spirits are inside of us, Mika!" Naruto was close to tears again for the third time that night.

Mika could hardly believe it. She possessed the Eleven tailed Wolf demon?

How was that possible?

Was she a monster?

Is that really why people hated the twins?

Mika cried with conflicting emotions for her brother and her the rest of the night and they talked continuously until they fell asleep in each other's arms to protect one another.

'Oh well. It hasn't bothered me yet. Let people think what they want.' Mika thought before she fell asleep.

The next day, everyone was surprised to see Naruto in the class but Mika walked beside him with pride in her eyes. Together, they sat in the third row close by the window, giggling stupidly.

Naruto perked up suddenly, "Oh! I forgot to tell you! I met this really weird little kid this morning. Konohamaru, the grandson of the Third. Man was he a little twerp."

"Naruto!" Mika scolded, "You can't just talk that way about the grandson of Lord third!"

"Ah, so what? The kid wanted me to teach him some moves so I taught him the Sexy Jutsu."

"You did what!?"

"Calm down sis, he mastered it! But then his stupid teacher showed up and yelled at me, Konohamaru did the sexy jutsu on him, didn't work so I did my sexy harem jutsu on him instead." Naruto seemed proud of it but Mika merely frowned at her brother with distaste as he continued, "He said that one day he would be Hokage so I just told him the facts."

"Facts?"

"That I was going to be Hokage and he'd have to beat me to it. We're enemies now, I guess. Stupid kid."

Mika held her head in her hand, "You're a dork, Naruto."

Naruto grinned at her and she smiled back with earnest.

"Hey will you let me through?"

A female voice spoke from beside them and Mika and Naruto turned to see that it was Sakura Haruno, the girl Naruto has had a crush on for years. Mika rolled her eyes.

"Naruto! Move your ass! I want to sit on the other side of Mika!"

Naruto looked a little shot down but they both looked beside them to see who she wanted to sit by.

Mika paled to see it was Sasuke Uchiha, the most popular boy in class. She wouldn't deny he was cute. However, Mika didn't like people who thought they were better than her. So she turned away. However, Naruto wasn't going down so easy and he glared at Sasuke.

Sasuke finally looked over to Naruto, "What?"

Naruto lost it, "What do you mean what?!"

Sakura piped up, "Sasuke! Can I sit next to you?" she tried sweetly it made Mika sick.

Sakura didn't need an answer however and sat with him anyways. Mika decided to look somewhere else and noticed Kiba staring at her. Mika blushed and looked away and Mika could hear his soft laughter at her shyness.

Suddenly there was a skirmish and everyone watched as Naruto was on the desk directly in front of Sasuke staring him down. They both glared daggers at each other. Sakura screamed for Naruto to leave Sasuke alone but then something horrible happened that made Mika almost lose her breakfast. A kid had accidentally pushed Naruto and made him fall into Sasuke where they accidentally kissed. Immediately, Naruto pulled away and started rubbing his tongue off.

Mika couldn't help herself and burst out with laughter at the scene. That is until Sakura cracked her knuckles. Naruto sweat, "Uh oh"

Sakura beat Naruto to a pulp. However, Mika didn't help her brother out this time.

"Mika!" he croaked, "What the hell?"

"You deserved it this time. Now pay attention. Iruka sensei is coming in."

All attention then went to Iruka entering the room, all events of Naruto and Sasuke's kiss forgotten.

"Starting today, all of you are real shinobi. But you are still Genin. The hard journey that lies ahead has just started. Now you will soon get a mission that will help the village. So today, we will create the three man teams. However, there will be one group with four. And each team will have a Jounin sensei. You will follow your sensei's instructions in order to successfully complete your missions."

Iruka continued, "We tried to balance each team's strengths."

The whole class erupted, "What?!"

Iruka named off the teams until he got to team 7, "Okay, next is team 7. This will be the four man team. Sakura Haruno, Naruto Uzumaki, Sasuke Uchiha and Mika Uzumaki."

Immediately Naruto was displease, "Iruka Sensei! Why does an outstanding shinobi like me have to be on the same team as that prick?!" he pointed to Sasuke. Although Mika couldn't help but to agree with her brother, Mika was still annoyed at his antics.

Iruka stopped him, "Sasuke's grades were the best of all 27 graduates and yours were dead last. You do understand we have to do this to balance the teams, right?"

Sasuke mumbled, "Just don't get in my way, moron."

Naruto growled, "What the hell did you say to me?!"

Mika stepped in, "Give it a rest, Naruto!"

Naruto stopped and looked away sourly.

Iruka sighed and continued once more, "Okay, this afternoon we'll introduce your Jounin senseis. Until then, take a break."

The class broke up fast and left the room. You would think that Naruto and Mika would spend their time together as brother and sister but usually they went off by themselves just like right now. Naruto went off to eat his lunch on a roof while Mika enjoyed a sandwich in the grass by her favorite tree. By the time lunch was over, she went back to the room with her brother and new teammates.

It was two hours until finally, Naruto had had enough and went to put an eraser at the top of the door so when someone entered, the eraser would fall on their head.

Mika rolled her eyes, "Naruto, what are you doing?"

"Why is our Team 7 sensei so freaking late?! All the others got to leave with their new sensei. Even Iruka sensei has left!"

Mika shrugged her shoulders as Naruto finished his prank.

Sakura scoffed at him, "What did you do?!"

"Serves him right for making us wait!"

"I won't be involved." Sakura declared and Mika rolled her eyes again.

"Such a skilled shinobi like a Jounin wouldn't fall for such a stupid trap." Sasuke mumbled.

However, Sasuke's comment was short-lived when a man opened the door, causing the eraser to fall on his silver head.

Naruto burst out in laughter, "WHAhahahah! You fell for it! You fell for it!"

Sakura quickly rushed to defend herself, "I'm so sorry sensei. I tried to stop Naruto but. . . "

Mika couldn't believe it. Her new sensei was the man she had met just a few days ago. Kakashi Hatake!

The silver-haired man with the blue mask on his face and headband over his left eye smiled, "Hmmm well based on a first impression of you four I'd have to say . . .You are very childish and I hate you."

Mika frowned and mumbled, "Story of my life."

Kakashi had heard the girl but merely stated, "Now meet me on the roof and we'll talk."

As soon as they got up to the roof together, the four children sat in front of their new sensei, waiting for him to speak.

The man smiled and started, "Let's start with a little introduction, shall we? Likes, Dislikes, and dreams of the future. Things like that."

Sakura piped up, "Excuse me sensei but could you go first? We don't know anything about you."

Kakashi hesitated but chose to acknowledge the request, "Well okay. My name is Kakashi Hatake. My likes and dislikes are things I don't want to tell you and my dreams are none of your business. But I have lots of hobbies."

Sakura muttered, "Well we learned his name."

Sasuke was silent while Naruto grinned manically to his sister, Mika. Mika merely smirked at her brother.

"Alright now how about we start with the boy in the orange, shall we?"

"Who me?" Naruto giggled, "My name is Naruto Uzumaki! I like cup ramen and even more so if Iruka treats me to ramen! I hate the three minute wait for the ramen to cook."

Kakashi looked thoroughly bored with Naruto's description until Naruto's voice changed with determination, "And my dream is to one day surpass the Hokage and then have the people of this village finally accept and acknowledge my existence at last!"

Mika beamed at her brother with pride and nodded.

"Oh! And my hobbies are pranks!"

The mood suddenly changed to exasperation.

Kakashi pointed to Mika, "You next, little one."

Mika blushed but spoke firmly, "My name is Mika Uzumaki. I like the rain, dogs, ramen and my brother Naruto. I hate cats, people who think they are better than me and . . . .Sasuke Uchiha."

Sasuke raised his head at this and scoffed at her while Mika continued, "My hobbies are drawing, painting, eating ramen and keeping Naruto in line."

Kakashi smiled, "But what about your dream?"

"Oh! My dream is to one day become a strong Kunochi just like Lady Tsunade and learn as many jutsu as I can before I die."

"Hm. Cheerful. Now the pink haired girl."

Sakura smiled, "My name is Sakura Haruno and I like . . ." she glanced at Sasuke and giggled insanely, "I hate Naruto. My hobbies are hairstyling and studying and my dreams are to one day . . . " she stared at Sasuke again and giggled once more, ending her speech.

"Right" Kakashi scratched his head, "Now the emo kid."

"My name is Sasuke Uchiha. I don't really like anything and I dislike a lot of things. And my dream is to one day kill a certain someone and restore my clan."

Sakura was practically drooling over herself but Mika and Naruto just glared at him in annoyance.

"Hm." Kakashi said, "Interesting. Now then tomorrow we will start a mission concerning the four of us."

"Oh boy! Oh boy! What is it!?" Naruto could hardly stand it.

"Survival training. But it will be different form when you were in the academy. This time, I'm your opponent. And this will freak you out! Out of the twenty-seven graduates only nine will be chosen as Genin. The rest will be sent back to the academy to train more. You four have a very low chance of passing my test."

The whole group's jaws dropped.

"Anyways, we will meet tomorrow on the training grounds. Bring all of your ninja weapons and tools. Oh, and skip breakfast unless you want to throw up."

Mika was terrified of what tomorrow would bring. After Kakashi had given them their instructions, they were sent off the get ready.

The next day, Kakashi arrived to the training grounds late but began to talk, "Good morning everyone." He tapped on an alarm clock to set it and he pulled out two bells, "Your task is to take these from me before time is up. If you don't have a bell by noon then you go without lunch and I'll tie you to one of those stumps over there."

Mika frowned and grabbed her rumbling stomach, 'Bastard.' She thought.

"You will be attacking me with the intent to kill."

Mika looked over to Naruto and gulped at his ignorance as he launched over to Kakashi. However, Kakashi easily avoided him and stood behind him, "Not so fast. I didn't say start yet."

"You came at me with the intent to kill, though. I think I'm starting to like you guys. Now get ready. . . Start."

The four kids launched out of sight.

The battle for lunch went very fast so to speak. Naruto as usual went in head first, got his butt kicked and lost. Sasuke went against Kakashi by himself and Sakura was powerless. Mika, however was the only one Kakashi couldn't find. Later, he found out, however, that she had been hiding underwater in the river, holding her breath and using a straw disguised as a twig.

Naruto ended up tied to the stump while Kakashi scolded them for not having any teamwork at all. He told them not to give Naruto any lunch or they all would fail. However, Mika wasn't going to let her brother starve and she fed her food to him. Sighing, Sasuke gave in as well and so did Sakura.

Kakashi came back instantly furious at first, "You ALL . . . .Pass."

Mika was the first to question it, "Pass?"

Kakashi smiled through his mask, "You four are the first you never did as I told you to. A ninja must be able to see the meanings through the hidden meanings. Those who break the rules and the codes of the ninja world are scum. But those you do not care for their comrades are even lower than scum."

The four Genin stared at their new master in awe.

Naruto was super excited and flailed around in excitement. Mika merely closed her eyes and smiled similarly to Sasuke.

The next few days were interesting to say the least.

After a few D ranked missions, Naruto had finally had enough of it and demanded that the Hokage gave them a real mission. Mika stayed quiet as usual, mentally scolding her brother.

However, they were surprised when the Third Hokage really did give them a different mission. A mission to escort a man to the Land of Waves.
