Kyuubi's Champion

By ShiyonYang

Chapter 1: He Has a New Goal and so Does the Kyuubi

A young boy with blonde hair, perhaps the age of eleven or twelve burst through the complicated passageways that was Konoha's red light district. Behind him was a crowd of drunken civilians and a few ninja, all wielding assorted weapons. Tears of fear and sadness rolled down the face of the child as his situation became more desperate, the angry horde was getting closer to him with each turn he took. Years of neglect and a diet of low quality food had left the boy weak, proving to be a huge disadvantage as he was finally cornered in an alleyway. With nowhere else to go but up, the boy started climbing in till a kunai found it's way in to his back, sending him plummeting down on to the trash covered ground with a loud thud.

"W-Why are you doing this to me?" asked the boy as he managed to slowly get back up on to his feet. The boy visibly flinched as he pulled the kunai out of his back, splattering hot, red blood on to the ground.

This had happened every year for the young ever since he could remember. Every year on his birthday, October tenth, the villagers would gang up on him and beat him. Most of the time they would only beat him in till he lost consciousness but sometimes they would hurt him enough to send him to the hospital for a few days. He didn't know what he did to deserve this. All they did was beat him and when they didn't, they just ignored him. He felt so lonely, he just wanted to be acknowledged. Why did everyone hate him?

"Demon! You dare defile my ears with your words! I'll kill you!" cried one of the shinobi as he threw a set of shuriken towards the young boy. The shuriken embedded themselves in to the boy's body, sending a loud piercing scream to echo off of the walls.

The child slumped down to his knees, feeling life leave his frail body as his blood ran down his shirt and on to the ground. Mustering all of his strength, he asked one last desperate question.

"What did I do to deserve this?"

"You disgrace the memory of our beloved Yondaime Hokage! Do you want to know what happened? The Yondaime never killed the Kyuubi! No. He sealed the demon inside of you! You're the Jinchuriki of the Kyuubi! Now die like the demon you are!" shouted one of the civilians, eliciting sadistic cheers of approval from the mob despite the law saying those who revealed such information were to be put to death.

The boy's eyes widened considerably as his mind shattered. They had known all this time? That was why the hated him? He wanted to scream but before he was even able to open his mouth, someone sent a kunai right in to his throat, sending him slumping to the ground with a thud. His vision blurred as the last thing he saw was the red Uzumaki swirl on the back of a chunin vest. The last thing he heard was the crowd's cheer of approval. Then everything went black.

As the crowd dispersed out of the alleyway, grins on their faces at the prospect that the demon was finally dead, an old man burst through and immediately fell to his knees as he saw the body of the boy. The blood seeped into his pristine white robes but he didn't care as he clutched the boy to his chest.

"Naruto, what have they done," he said solemnly, tears starting to flow down his cheeks as he looked in to the Heavens above.

"Minato, if only you could see what Konoha has become."

Naruto's Mindscape.

*Drip, drip, drip.*

Naruto wandered aimlessly through the tunnels of what appeared to be the sewers. He didn't know where he was, all he was capable of doing right now was commanding his feet to move. Strangely enough, he felt like an invisible force was guiding him through the seemingly abandoned maze.

"Did they dump me in the sewers?" thought Naruto as he continued dragging his tired body through the thick, filthy water.

He continued walking for what he perceived as several minutes in till he found himself in front of a large metal cage with a paper seal in the middle. He no longer felt the invisible force guiding him as he stood in front of the intimidating metal bars.

"Hello?" he called out. His voice seemed to echo off the round walls, bouncing off every surface in till his voice faded away.

"Ahh, it seems my container has finally come to visit me," boomed a voice, filling the entire chamber with strong vibrations. Naruto barely flinched.

"Who's there?" he asked, as he squinted his eyes to see where the voice was coming from within the darkness inside the cage.

"Kyuubi no Yoko, at your service," boomed the voice once more, starting in a very deep and masculine voice that slowly turned slightly more feminine with each syllable.

The Kyuubi's silhouette appeared shortly after. As it got closer to the metal bars, it revealed it's magnificent size to Naruto. The fierce features of the Kyuubi barely fazed Naruto. What surprised the Kyuubi the most was that Naruto had actually walked forward instead of cower away. Naruto's eyes widened slightly as it studied the Kyuubi before dimming in defeat.

"So it's true then. I am a demon" sighed Naruto as his once full of life cerulean eyes glazed over and turned cold and dead. The Kyuubi's ears drooped slightly as it stared at the boy before him. Shortly after, Naruto looked back up at the Kyuubi and met his stare without hesitation.

"It appears that my container is brave. Good. I can't have myself a cowardly container," it said as it dipped it's head so that it could get a better look at Naruto.

"But you are wrong. It seems you do not know the difference between a scroll and a kunai," it said, confusing Naruto.

"What do you mean?"-

"Does a scroll become a kunai if a kunai is sealed inside of it? Of course not. Just as you are not a demon for having a demon sealed inside of you. You are simply the scroll while I am the kunai," explained the Kyuubi, getting an understanding nod from Naruto.

"So, where am I?" asked Naruto.

"This is your mindscape, kit. You have absolute control in here because it is your mind," answered the Kyuubi, getting another understanding nod from Naruto.

"Give it a try, kit. Think of anything and it will appear inside your mind."

Naruto gave it a prompt nod before he closed his eyes. The damp sewers that once was slowly faded away and gave way to a beautiful meadow. The meadow had vibrant flowers scattered around and a soft hill with a tall apple tree for shade. The sky was set in a beautiful sunset, the same sun set Naruto watched everyday on top of the Hokage Monument. The cage that once held the Kyuubi was turned in to a thin white collar with a tag that said seal.

"It seems my container also has a beautiful imagination," it said as it gazed longingly at the gorgeous scene created by it's container.

"So, I've noticed that your voice has gotten a bit more girly. Are you a girl?" asked Naruto.

"It seems that you are also clever, very good. And yes, I am indeed a woman," she answered as she slowly morphed in to a beautiful woman.

She had long, rich red hair with elegant fox ears sticking out on the top of her head. She happened to be completely nude when she finished transforming, without a single strand of hair on her body except on her head. She had flawless, milky skin that most women would kill for. She had large 86D cup breasts, each adorned with a pretty pink nipple. She had a very shapely body, with a thin waist, a very toned stomach and beautiful, delicious thighs. Between her perfect thighs was a neat patch of trimmed red hair, above her pink slit. She was like a goddess, with a body so beautiful that it would drive men to murder if she ordered them to.

"W-Wow," said Naruto, eliciting a cute giggle from the Kyuubi.

"So, tell me kit. What is your goal in life?" asked the Kyuubi.

Naruto was taken aback by that question. If anyone had asked him that question on any other day, he would've proudly exclaimed his goal to become the Hokage. He didn't feel like the villagers deserved his protection anymore, not after how they had treated him. After a few seconds of deep though, he replied.

"My goal in life is to make sure that no one else has to go through what I've been through. Jinchuriki or not. No matter what!" he replied passionately.

"Good answer, kit," she said as she suddenly placed a soft hand under Naruto's chin. She slowly raised his chin so that he was looking up at her and then she proceeded to plant a gentle kiss on his forehead, sending slight shivers down his spine.

"W-What was that for?" asked Naruto with a blush as he felt Kyuubi's soft lips leave his forehead.

"Just a small reward for all that you have endured," she replied warmly.

"O-Okay," he said, the touch of the Kyuubi's lips still lingering on his forehead.

"I've decided to make you my mate," she said suddenly with a smile.

"W-Wait. What?!"

"You heard me, I'm going to make you my mate and it won't do to have myself a weak mate so I'll be making a few changes to your body," she replied with a foxy grin.

"What kind of changes?" asked Naruto.

"I'll be using my youki to do some tweaks to your genetics. By the time you wake up, you'll be stronger and faster. I will also be granting you a few kekkei genkai. I'll unlock one for you every once and a while since I do not want to overload your body," she explained elegantly.

Naruto quickly nodded.

"Now, the first kekkei genkai I will be adding to you will be the Akuma Fokkusuai. It allows you to read emotions, see in to people's minds and manipulate them," she began, "But you have to be careful because once you use it, you can't reverse the effects of it."

"All right," he replied in understanding.

"It's weird that I'm going to be your future mate without even knowing your name," said Naruto, earning him a smile from the Kyuubi.

"You may call me Yoko," she replied with a flip of her silky, crimson hair. Her lips curved in to a grin.

"Now go! Spread terror in the name of Kyuubi no Yoko! Make them fear me as they have before. Become my champion and I will help you achieve all of your dreams!" she said proudly as she posed with her arm extended and her finger pointed towards the distance. With that said, Naruto could feel his mindscape fading, a bright light seemed to dominate his vision as he woke up.

Konoha Hospital.

The occasional beep of the heart monitor was there to fill the silence that was Naruto's hospital room. Naruto awoke slowly. His eyes opened groggily as he slowly raised himself, only to be stopped by the sharp pain that went through his body. He decided to lay back down. His movements didn't go unnoticed though as the Hokage quickly made his way to his bed. The old man gave him a sad smile.

"Naruto-kun, how do you feel?" asked Sarutobi.

"Like someone who was just used for target practice," replied Naruto in a very empty tone that worried the old man.

"I'm sorry, Naruto-kun. If only I had kno-,"

"No, it's alright," interrupted Naruto, "There's no need to apologize."

"How long was I out?" asked Naruto.

"A little more than a day," replied Sarutobi, "Do you need anything?"

"I'll be fine, Ji-san," said Naruto, giving Sarutobi his best winning smile.

"Alright, Naruto-kun. If you ever need me, you will know where to find me," said Sarutobi as he gave Naruto one last sad smile before standing up and leaving the room.

The moment Sarutobi left the room, Naruto's smile immediately fell, revealing his void eyes and his frown. He turned his head to his right, so that he could gaze through the window in to the village.

"Someday, I'm going to show you all exactly how it feels to be me, I'm going to burn this place to the ground," he thought as he mustered all his hatred in to his eyes to glare at the villagers below.

"I'm going to make sure no one else has to go through what I've been through."

"Don't worry kit, I'll be here to help you," said Yoko in her melodious voice.

"How are you talking to me?" asked Naruto.

"Well, when you were sleeping, I found a way to slip myself through the seal and that is how I am communicating with you," she replied.

"Oh, alright."

"So when do we begin my training?" asked Naruto.

"As soon as we can. First let me tell you the changes I've made to your body," responded Yoko in her explaining voice. Naruto nodded.

"First, I have given you the Akuma Fokkusuai. To activate it, all you need to do is channel youki in to your eyes and look directly in to someone's eyes. To give orders, you have to just think of the orders you want to give them," explained Yoko.

"What if their eyes are closed?" asked Naruto.

"You can always just channel youki in to your hand and touch them on the forehead," replied Yoko to which Naruto nodded once again.

"Now. During your sleep, I've made your body stronger. You see, I've made it so that when you exercise, you'll gain twice the benefits. For example, if you exercised for ten hours, you would be gaining twenty hours of muscle and don't worry. I've made it so that you won't be too bulky, so you'll be lean and flexible," continued Yoko with a smile on her face.

"Now I before we start training, we have seriously got to do something about your outfit," instructed Yoko.

"Alright?"

"No resisting? Good. Henge yourself and let's head to the market district."

With a nod, Naruto immediately pulled out tubes, henged himself as a young, brown haired, generic boy before opening the window and jumping out.

Market District.

Being henged as a different person really changed the way people looked at him. It was like a weight was being lifted off Naruto's shoulders, if only briefly as the villagers all smiled at him as he made his way to the shinobi clothing store. When he entered the store, he was welcomed instead of kicked out. This only made his hatred for the villagers grow more.

"Hey, mister. Mind explaining all the stuff you got here?" asked Naruto in the most childish voice he could muster.

"Sure! What do you need?" replied the man with vigor reserved only to the villagers.

"Well, I need some new clothes," said Naruto as he looked up in thought.

"Come with me," said the man as he gestured towards the clothing section.

Naruto followed the man as he explained all the different materials and what they were good for. Some were woven with kevlar, protecting against grazing blows and some had steel plates attached to them for extra protection. There was camouflage clothing for almost every environment, even a pink one for hiding in Sakura trees.

"I'd like to have these," said Naruto as he picked out a subdued black trench coat, a thin light grey vest, a dark grey shirt and grey camouflage pants, "I would also like to buy multiple sets of these, except for the coat and vest."

"Sure, young man," said the shopkeeper as he ringed up the prices of all the clothing on his register.

"That'll be fifty-thousand yen, please."

"No problem," said Naruto as he pulled the money out of Gama-chan.

"Please come again, young man," said the shopkeeper as he waved off Naruto.

"I will," replied Naruto out of habit as he walked out of the store, holding the bag of the items he had purchased.

Naruto had to stifle a chuckle as he walked out the store. What child carried around fifty-thousand yen?

"Idiots," he thought as he looked up in to the sky.

"It's getting late. Let's head home so I can start your training tomorrow," said Yoko.

With a quick nod in affirmation, Naruto immediately dropped his henge and disappeared in to the night. He dashed over the buildings in till he reached his run down apartment. He just simply slid through the hole in his window and quickly went to his bed.
