Dark Text is Demon Speech

Slanted text are Thoughts

Summery: After the battle with Zabuza and Haku, Naruto discovers something very wrong with his 'Tenant' who is nothing like what he thought.

I do not own Naruto

___________________________________________________________________________

"Hey Brat, Wake Up!" Naruto tried to ignore the voice that was ringing in his ears.

" I'm going to bite your head off if you don't get moving!" The Voice Bellowed once again.

Naruto mind started to started it's gear as it was processing the information his ears just received.

'Wait, EARS?' Naruto was used to that little voice nibbling at the back of his mind but hearing it coming from the outside terrified him. Slowly opening his eyelids, he noticed the world was more red then he remembered. Blurs of red and orange filled his head. Everything quickly cleared and the blurs of red and orange were now floating in front of him.

"So, you're finally awake, huh?" Said the Red and orange thing. Naruto, who at the time was speechless just stared at the fox demon incarnate. It looks like a small piece of fire in the shape of a fox's head with two orange eyes that seemed to actually look at him. Moving his gaze downwards he saw the source of the piece of talking red fire, the seal on his bare stomach was completely visible.

" Wh-wh-what are y-you?" Naruto asked hoping it wasn't what he thought it was?

"DUDE, You don't know me? I've been sealed in you for like YEARS!" The Fox replied.

"B-but you're….here!?" Naruto continued.

"Well, that's completely your fault. You activated fail safe 23 however you may want to ask the guy outside your door first" The fox answered as it turned it's attention to the bedroom door. It slowly opened revealing Kakashi with a dangerous look spread across his face.

"Yo, Nice to meet ya, one-eyes!" The Fox said cheerfully not understanding the situation he was in.

" Please do go on with the explaining this outcome. " Kakashi attempted to say in his most threating voice he could muster. He had sensed the chakra and came expecting to have to subdue Naruto but this was something he was not prepared for.

"Oh, yeah that. Well whoever seal me in here has left A LOT of his chakra. All of it going to fail-safes embedded into the seal. For example, my personal favourite is fail-safe is 102, which pretty much is a way to contain me in a secondary seal if Naruto here drinks too much spoiled milk and I start to escape from 'there'." The Fox paused for a small chuckle. "As if a son of the Great Kyubi would leave through such a unsightly manner."

"S-son?" Kakashi vaguely asked.

"Well, duh. I am the second son f the great Kyubi! My only dream in life is to surpass my brother is gain the title of Lord of the Foxes!" The orange Chakra announced.

"…And's that why you attacked the village, trying to prove yourself." Kakashi quickly deduced.

"Yup, I tried to be the only fox under 6 months old to take down a Ninja village but as you can see, I failed." The fox chuckled out.

Naruto who had been quiet all this time managed to spit out. " How are you here?"

"Well, whatever happened yesterday caused you to bring far too much my AWESOME chakra into your body. It would of gave me control your body which activated fail-safe 23. Which places me in this ghost like state, so you can still get my advantages without worrying me controlling your body. After playing around with him asleep I found out I can't physically touch anything with a little of the brat's chakra"

"BRAT?! You're barely older then me!!" Naruto automatically retorted to the insult.

"I can kick your ass anytime I want!" The Chakra yelled. Naruto responded by wrapping his hands around the chakra and began shaking. A thin string of red chakra appeared around Naruto's neck. Kakashi just stood there trying to take in everything he learned while watching the two 'kids' strangled each other.

"Ok, enough you too." Kakashi ordered. 'If these two don't stop they make attract his team mates which is not something we need right now'

"What do you want to do now, Honourable Son" Kakashi ponder while trying to keep the son of the most powerful demon happy.

"Please don't call me that one-eyes, I want to be feared for my power not because of my father." The fox growled. " but all I wanted and still want is to defeat my brother."

"How would you do on to doing that?" Naruto asked without trembling, getting used to the piece of chakra.

"I dunno, I'm just going to wing it. What abut you kid?" The fox replied.

"I'M GOING TO BE THE GREATEST HOKAGE EVER.!" Naruto shouted with all his enthusiasm which was pretty much a reflex at this point.

"Well, I'm going to guess we're both need power, but one question first." The fox said. "What's a Hokage?"

_______________________________________________________________________________

Several Hours Later…..

Kakashi watched Sakura and Sasuke talk about his blood limit from the corner of the room. He had sent Naruto into the forest and attempt to figure out of the strengths and weaknesses of his 'predicament'. Kakashi already had a plan on how to inform Sasuke and Sakura. They had to know, they were his team mates after all and they needed to know stuff like that.

"…Just a another step towards my vengeance." Sasuke ended the conversation with those words. Kakashi frowned, he had hope this battle on the bridge had humbled him or done something to his attitude. Sasuke instead took the battle with Zabuza and haku as a victory.

" Well Sasuke, when we get back I have a lot to teach you. " Kakashi announced as he moved to the center of the room.

"Hmm." Sasuke answered but from the look on his face anyone can tell he was immensely happy.

" Where's Naruto? He should come look at Sasuke's eyes.!" Sakura yelled.

"Well, actually that's what I would like to talk to you two about." Kakashi began his explanation.

_________________________________________________________________________________

Meanwhile……

Naruto collapsed on the ground with the little fox head hovering over him.

"Well, that clears up a lot of things." Naruto panted out to his partner. They have found out the fox can only interact with the outside world if Naruto pushes some chakra into him. They assumed it was to protect friends from getting hurt. They also learned he can come out of any chakra point thus always having the element of surprise. Maybe the most important one was fox's ability t perform hand signs. This meant they could theoretically pull off two different jutsu at once.

"Man, is my brother going be surprised when I pull off a amazing jutsu!" The Fox cheered.

"Why Can't he pull off jutsu?" Naruto asked.

"No, fox don't have fingers so we never really tried but now I can do it!" The Fox answered before continuing " So what jutsu you going to teach me?"

"Why should I teach you? That's why we have a teacher you know." Naruto stated.

"Naruto….what was our deal." All of the fox's enthusiasm dropped from his voice.

"Heh, I guess I should then. " Naruto said.

"SAY IT!" He shouted.

"….You're going to help me became HOKAGE!! Then I'll help you surpass your brother then we can become….THE DEMON KING HOKAGE!" Naruto proudly shouted.

"I don't know about that title. King Hokage seems redundant….How about The SUPER EVIL EVIL HOKAGE!!!" The Fox yelled.

"WHAT?!! EVIL EVIL?"

________________________________________________________________________________

Naruto made it back to Tazuna's home only be to greeted by silence. They would be leaving tomorrow but Naruto wished they would leaving at that moment. He didn't know what Kakashi told then so he was hoping they would start the conversation. Luckily fate was on his side.

"So Kakashi tell us you also unlock your blood limit during the attack." Sakura started.

Kakashi started on the details. " Yes, Naruto has activated his…oversoul. This allows him to communicate with his chakra. While very powerful and useful, it's not on the same level as the sharingan.

Naruto nodded while he would want to fight with Kakashi about the power of the Kyubi's son he knew Sasuke's ego had to be stroked. Last time it was bruised Sasuke competed against him on everything until he pissed faster then Naruto.

"Yeah, that's about the just of it….So would you like to meet him?" Naruto asked.

"What do you mean meet him. Isn't he just Chakra" Sasuke inquired.

" I'm not just Chakra! I'm K-" The fox popped out of Naruto's chest and almost blew the lie out of the water however Naruto shut him with a quick jab to his head.

"I'm K-" "Kuu! I've named him Kuu!" Naruto lied through his teeth.

"Kuu? You've named Chakra, Kuu?" Sasuke tried to make sense of what just happened.

"Damn, Naruto you never told me how pretty your team mate was. " Kuu said as he eyed Sakura who in turn blushed at the comment, as he tried to change to subject.

"How nice of you Kuu!" Sakura yelled.(which she does a lot of)

Naruto grumbled something about how he told Sakura she was pretty and getting a fist to the head. Sakura was busy trying to pet Kuu, Sasuke was thinking of the possibilities of this power and Kakashi was thinking of porn.

Sasuke seemed to want to get to know more abut Naruto as they Journeyed back to the village. He fired questions like Kunai.

"Where were you Born?"

"Who were your parents?"

"Can you make anyone's Chakra come alive?"

"What's it feel like?"

"Does it make you feel stronger?"

Naruto finally snapped and requested Sasuke take a break from the questions. Shockingly he did stop and he pulled back in line with Sakura. Naruto was a little nervous this created some barrier between them but t place his mind on other things as there was nothing he can do about it. Looking for Kuu, he found a string of red chakra come from his shoulder and towards Kakashi, look at what Kuu was staring at, Naruto couldn't help but smile.

" Wow, I didn't know Chakra can blush!" Naruto stated loud enough for everyone to hear. Kakashi looked behinnd himself and saw Kuu looking at his 'orange book'

" I do not!" Kuu spat back. Sasuke and Sakura could only stare. I mean, what do you say to a guy who's arguing with his chakra.

After a few hours of Naruto and Kuu arguing over everything from girls, jutsu and even what color grass was. Sasuke was about to go insane, Kakashi sensing that Sasuke was pushing Chakra into his legs to catch up to Naruto.

Placing his arm on Sasuke's shoulder he whispered. "Naruto really hasn't have anything considered a family member. Let him enjoy his unusual happiness."

'You owe me one. BOTH of you do'

_____________________________________________________________________________________

"Ah! Team 7 welcome back, I presume the mission went without a problem." said the Third Hokage.

"Actually, the mission rank was changed mid-way through the mission." Kakashi replied the Hokage who now looked horrified.

"What rank, do I ask was it?"

"I'm afraid, Lord Hokage it was bumped from C-class to B-Class then A-Class soon after." Kakashi said with no hint of emotion in his voice as he placed the mission report.

Minutes passed very slowly as team 7 was waiting on what the Hokage was going to say.

"Well, I'm very glad everyone made it through without a permanent injury. In fact, it seems you came back even stronger, however don't let this get to your egos. On many other A-Class missions someone would of gotten injured or even died."

"Yes, Lord Hokage" Team 7 said in unison.

"Ok, you are dismissed." He ordered, the team turned to leave. "Kakashi, Naruto please remain here as we have much to talk about."

Minutes once again passed slowly as Hokage waited for his assistant to gather up some scroll before leaving the room.

"So, Explain what has happened to the seal, please Naruto." Hokage asked.

"HEHEHEHEHE, NO NARUTO, ONLY GOD!!" Kuu said in the darkest voice he could muster.

The pipe flew out of the old man's mouth and into Kakashi's face. Kakashi preceded to smack Naruto at the back of the head.

"Hey! It was Kuu's idea!" Naruto defended himself.

"WHAT! It was all you!!" Kuu shot out of Naruto stomach and began arguing.

"Kakashi, explain NOW!" Sarutobi ordered as he stared at Kuu and Naruto fight.

Kakashi then spilled everything he knew, however Sarutobi wasn't really surprised, he knew Minato was a genius and all of this wasn't completely impossible but very unlikely.

"Well Kuu, I have some question for you." Stated the Hokage.

"Go ahead old geezer." Kuu responded.

"Why do you allow us to call you Kuu? Some what Kakashi has told us you seem to have a lot of pride. Why allow us to name you?" Sarutobi pondered.

"It's my first name, of course I'm going to keep it!"Kuu said cheerfully. "Most demons back then just called me Kyubi's son, much to my annoyance. "

" Do you affect Narutos mind in anyway? The third Hokage continued.

" Nope, that was the reason the fail-safe was activated. Naruto channelled far too much of my awesome chakra into his body, it was slowly giving me control, so I was placed over he chakra. This way he gets all the benefits and none of the mind control. Even though anyone who wants inside this kids head has to be crazy!" Kuu answered.

"WHAT!" Naruto screamed.

_____________________________________________________________________________________

Naruto laid across the field resting from a hard practice session, with scrolls open and spread across the ground around him. Kuu was going through scrolls looking for a easy jutsu to learn.

"Man, these are too hard!" Kuu ranted.

"Not really for the future Hokage but for a lowly demon I guess they can be hard." Naruto teased. Kuu shot him a look before turning back to the scroll.

While it was possible for Kuu to pull off jutsu, he had a lot of trouble pulling them off. It took hours for him to learn the hand signs and even more to pull it off badly. So far after a couple days of training he's only learned Shadow Clone Jutsu, and was getting hang of Fire Style: Fireball Jutsu which was strangely provided by Sasuke.

'Man, these jutsu thing barely seems worth it. It's way to hard for a attack, I'd much rather just bite or swipe my enemies' Kuu thought as he continued to fail at a simple water jutsu. Kuu tried tossing the scroll but went through it, looking back at Naruto he found him asleep on the grass. Kuu frowned when he spotted Naruto shivering from the cold air. Kuu focused himself on all of Naruto's Chakra points until Naruto was enveloped in a cloak of red chakra. The desired effects occurred as Naruto stopped shivering and a very relaxed looks spread across his face.

Sasuke watched the screen from a nearby tree, while usually he tried to ignore he blond haired team-mate but since he came back with so much power, Sasuke couldn't help but investigate. The word 'demon' was often passed along between Naruto and his Chakra which only fuelled Sasuke's interest. When Naruto came into the Tazunas house with that power Sasuke nearly exploded in questions. He recognized immediately the power of this 'Bloodline' and all he could think of how strong would he be if he possessed it.

'No way that's a naturally occurring Bloodline. Somehow Naruto got that power, and if Naruto can't help me maybe I should just to the source. Not even Itachi can defend the power of the Sharingan and the power of that chakra.' Sasuke thought to himself as he left he hiding spot as Naruto was taking a nap.
