Well hello to all my readers! I know, I've been busy for a long time but finally the chapter four is here!

Like always, I want to thank you all for the feedback that this story is getting. Not only the readers who favorited or are following this simple fanfic, but also for the excellent reviews you sent me! again, you rock guys.

This chapter is the begining of the training of Yami and Naruto, although I won't be very descriptive and they begin it at the end of the chapter. Note that after this chapter there will be a Time Skip of a few years. And then, Yami will discover her true feelings for Naruto. (Yeah, lemon is close hehe)

Anyway, I know some of you didn't liked the previous chapter and I'd like to apologize with you all. I hope this is better.

Disclaimer: I don't own Naruto or Yu-Gi-Oh!, If I did then I'd be a japanese guy and the creators of those fantastic series would be from Argentina hehe.

Pairings: Fem!Kyuubi/Naruto/Fem!Naruko/Fem!Winged Dragon of Ra.

Warning!: Incest and Lemon in the following chapters (not this one).

And... another chapter boring. Please deal with this, I'm really busy with school and test.

Chapter Four : Kyuubi

Naruto awoke feeling dizzy. His eyes were slightly opened but he could see that he wasn't in the Hokage's office anymore. However, his first sight of the day was the little face of his lovely sister.

"Nichan!", the shout echoed through the room. Naruto's eyes widened as he felt a pair of arms hugging his neck.

It took him a few moments to recognize where he was, but then he remembered everything. It appeared that he was in some hospital's room, more precisely, he found out that the place were the Konoha's Hospital. Still, how he got there, was a mystery. But in the end he was going to find that out.

He smiled sadly as he felt hot tears falling in his shoulder, Yami was sobbing quietly as she hugged him the most tightly that she could. "Hey Yami-chan..."

The voice sent a pleasant shiver down the girl's column. She couldn't help but smile in relief as she felt the soft hand of Naruto stroking her hair. "You scared me, baka"

Naruto chuckled shortly, "Aww don't worry so much for me Yami-chan, you know I'm not going anywhere. Besides...", he said gently pulling himself for the —now calm— girl and looking directly in her big-violet eyes. "...you're not going to believe what happened during the time I was unconscious. By the way, how much time passed from then?"

She was going to answer but then the Sandaime Hokage entered the room through the door and Yami let go of him as she sat in the chair next to the bed. Just as he entered, Sarutobi gazed to the now awaked boy and smiled in relief. "Naruto-kun!, I'm glad that you're awake. How are you feeling?"

"I'm fine, just a bit dizzy", he answered massaging the muscles of his neck. "In fact, I don't know how I get here. Do I have to suppose that you carried me here?"

Hiruzen nodded as he walked next to Yami and looked at the window. "Yes. I, along with Yami-chan, brought you here. Can you imagine how the medics reacted when they saw you unconscious?. They... they...!", Sarutobi couldn't say anymore. The simple memory was too much for his nerves.

Naruto gazed at Yami who seemed a bit sad for what the Sandaime said. Now the boy wasn't a genius —even with all of his intelligence— but he immediately realized what happened with the two of them. "They accused Yami-chan, didn't they?", Sarutobi nodded as an answer to Naruto's question. "I see... look, you don't have to worry for what they said. Those doctors are just ignorants, and they don't know that you aren't a threat for anybody"

"I know, it's just...!", she looked back to Naruto with a pleading look. But when she saw his calm smile she sighed as an attempt to calm down. "Sorry Nichan..."

The boy chuckled and patted her in the head for a seconds, smiling when he saw her pout. "It's okay, just remember what I said and everything will be fine", she nodded and Naruto looked at Sarutobi again. The old man seemed lost as he looked through the window. "Hey jiji, I know I fell unconscious before but how much time-?"

"Almost two hours", Hiruzen interrupted him not caring to look at the confused boy. "The doctors almost celebrated that you were fine. But the thing I didn't explained to them was something really particular", the old man said turning to him this time. "Two seconds after you lost conciousness, the tatoo on your back begun to glow with an intensity I never saw before. Now, I'd like to ask you if something happened during your state"

Naruto looked pretty surprised by that statement. He knew that Sarutobi would find the truth about his conversation with Atem and Ra, and for that, he decided to tell him what happened. Even if it sounded ridiculous, Naruto didn't wanted to lie.

'Naruto-sama, you can't tell him what happened between us. Don't you remember what we talked a few moments ago?'

The boy, almost startled, held back his emotions as he looked pretty serious. But, in his mind, he was talking with Ra. 'Ra-chan you scared me!', Naruto thought as he heard an apologize from the dragon. 'Okay, I'll do as we planned. I only hope that she can train Yami-chan'

"Jiji", Naruto finally said looking at him with decision. Sarutobi seemed surprised for a minute, but in the end he nodded. "I had a strange dream, in where someone talked to me"

"Do you remember who it was?"

He shook his head in disagreement, "No. But it said that neither I nor Yami-chan are ready for the Academy". Naruto said, pausing for a moment to gaze at Yami who seemed shocked with that. "And it was pretty clear when it talked, so, I'd like to reject the invitation to enter"

Yami Uzumaki couldn't help but widen her eyes in surprise and shock. Naruto, her brother, rejecting the oportunity to be a ninja? why?. But all her answers were momentary silenced with a simple nod of Naruto. Looking in his eyes, she realized that he was going to tell her something important. Still, it wasn't the moment.

"Naruto-kun, are you sure?. I have always believed in dreams, but I think that you should think this better", Sarutobi tried to reasure with the little boy. But when the Uzumaki shook his head, he couldn't help but wonder what kind of dream he had.

Oh well, maybe later he'd find that out. "Okay then, if you are sure then you're free to leave now", Naruto nodded as he stood up from the bed and dressed quickly. Yami couldn't help but look at the black tatoo on her brother's back. It was so realistic that it seemed a real dragon descending from its flight.

"Well Jiji, I suppose we'll see you tonight at your mansion", Sarutobi nodded thoughtfully. He was still shocked by what Naruto said. "Okay then, good bye"

Naruto took Yami's chan gently and toghether they walked to the room's door. Hiruzen smiled back at Yami who was waving her hand at him until they crossed the door and disappeared from their sight. Just as he sighed and was about to leave, he heard a nurse screaming with joy. "Naruto-kun you're awake!"

'I just hope that the doctors don't treat her bad, Yami was pretty worried about Naruto. Now, I wonder if she... Nah, just my imagination', Saruboi chuckled before disappearing in a whirl of leaves.

Yami blinked in confusion as her brother finished the story. Both of them were in an unoccupied training ground, Naruto with his arms crossed on his chest and resting his back against a tree. His sister, instead, was sitting in the ground. Her face showed a pout of confusion.

"So... are you saying that a 'Egypfien' God is living inside your body?", she asked making Naruto chuckle at her misspelling.

But after a second, Naruto nodded with a grin. "It's 'Egyptian God'. And yes, that's why I have the black tatoo on my back I guess. I didn't asked Ra-chan about that", he then pointed to her. "But that doesn't mean I'm abandoning you or something like that. When I become Pharaoh, you'll be my queen"

Yami returned the grin at him, happy with her brother's care. The fact was, that neither Naruto nor Yami really understood the meaning behind being the 'queen' of the Pharaoh. Ra mentally sighed, she needed to explain that to Naruto later. But now, it was time to talk with her.

"I trust you Nichan, really I do. But I've one question to ask you...", Naruto's grin faded and he looked serious again. "If this... Ra talked to you and you're completely sure about being the next Pharaof-", she stopped when her brother corrected her again. "Right. Well, my question is... why you decided to decline jiji's offer?"

Naruto shrugged at that, "Ra-chan offered me complete training. Not just what they teach in the Academy, but also much more".

"I understand", Yami answered as she thought her next question. "But if a God is going to train you, then why you said that I wasn't ready too?. I know that you can talk with Ra and she'll train you, but what about me?"

'It's time... Naruto-sama, let me warn you. She's really tricky and I don't know if she'll accept what we ask. You must be ready for anything'

The voice of Ra alerted the boy. Nodding to himself, he walked to the little girl and sat in the ground in front of her. "Yami-chan, close your eyes"

Yami tilted her head cutely to the side in confusion. "What? why?"

"Please, trust me. I'll show you something", Naruto answered completely serious.

As she noticed how serious he was, she did as the boy asked and closed her eyes. Breathing deeply, he put a hand on her forehead and concentrated on Ra's voice. Soon, they were in a different place.

Yami's eyes opened as she found herself sitting next to her brother. Looking around, she noticed that they were in what appeared to be a sewer. The walls were gray, but instead of just that, there were a lot of pipes that glowed with a blue light. Under her, the deep yet clear water was flowing calmly like a river but neither she nor Naruto's clothes were wet.

Looking to her side, she noticed that Naruto had his eyes closed and she couldn't help but feel worried about him. "Nichan! wake up!", she screamed gently shaking him up.

"I'm awake Yami-chan", he growled as he held his eyes closed. "Ra-chan is telling me where... Ah!-", Naruto suddenly stood up and dragged Yami to her feet. "This way!"

Grabbing her hand, Naruto walked through the sewers as he followed a path that seemed to be the most noticeable. "Err... why are we here? what is this place?"

The boy kept walking, but he heard the question. "This is your mind Yami-chan", he explained, not really wanting to stop there to explain everything.

But as she was about to ask something more, Yami forced herself to stop as she noticed that her brother was looking rather impressed to something. "What-?"

Yami's eyes widened as she noticed what was ahead them. It was a large cage with odd black symbols that glowed with a purple energy along the bars and in the center was a piece of paper with, what appeared to be, a seal. Now, Naruto didn't knew exactly what it was but the Sandaime had already showed him a few seals on some scrolls and he could guess that it were something pretty similar to that.

"N-Nichan what is that?", Yami asked but she got no answer.

Naruto was focusing in the voice of Ra inside his mind and he begun to walk. 'Yes that's it Naruto-sama. You need to walk to the Kyuubi's prison and talk with her'

He snorted at that, 'Ra-chan I'm a bit scared. Are you going to show yourself here?'

'Well...', she sighed before answering. 'I don't know how she'll react to your presence. Maybe she'll use her Kitsune form, but if you're lucky, the Kyuubi will be interested in you'

"Interested?", he asked loudly as he and Yami stopped a few meters away from the cage.

Yami was behind him, covering her little body with fear in her eyes. Naruto was scared too, he was about to face the real Kyuubi no Yoko.

"So... the Pharaoh has finally come, huh?. I've been waiting for you", despite what Naruto thought about how the voice of the biju would sound like it was pretty soft.

And soon as the figure made herself visible from inside the darkness, Naruto blushed as well as Yami. But the eyes of the boy didn't looked downside her face, even if at first he saw her naked. Yami found herself pretty confused and embarrased about that woman behind the cage, but she refused to look at her.

Even as she stood behind the cage, Naruto found the Kyuubi extremely beautiful. She wasn't as beautiful as Ra, but it was incredible how pretty she was. With her long red hair tied in a braid, her dark golden eyes and fair-skinned body she could be irresistible to any man that would see her. Kyuubi had small lips, whisker marks on her face —just like him and Yami—, two red fox ears and a red necklace.

Just like Ra, she had a perfect figure with nice breasts. Again, they weren't too big just perfect but, instead of looking exactly like Ra, she appeared to be a teenager in her seventeens. (A/N Of course that Naruto didn't noticed that, he was a kid after all. I'm just explaining this) But instead of one golden tail, she had nine fox tails that were swaying wildly behind her naked body.

"Why every girl that is sealed inside someone has to be naked?", he asked loudly, hoping that the Kyuubi would hear him.

She snorted softly, her hands toured her delicate figure with lust. "What's wrong? do you like what you see?", she asked with a teasing smirk on her face.

But instead of getting embarrassed or denying it, he played along with her. "Yes, you're like a goddess"

Yami looked at her brother surprised, "Nichan! are you a-?"

"Trust me", he whispered interrupting her. Then, the girl widened her eyes in realization.

Both turned to face the Kyuubi who know had a blush on her face and was looking surprised at him. 'Is he...?. No, of course not. He's playing with me'

Snorting loudly, she snapped her fingers and a red kimono covered her body. Now then, Yami sighed and looked calmly at her. Still, she was a bit confused. "Nichan, who's she?"

"Yami-chan...", he turned to look at her. He didn't knew how she was going to assume what he had to say. Of course that after a good explanation she'll understand it, or so Naruto hoped. "This girl is the Kyuubi no Yoko. She's the reason why everybody treats you like a demon"

The girl immediately loosened the grip on her brother's arm, her eyes widened with surprise. "W-what? b-but how?"

Naruto's face acquired a grim look, but the Kyuubi, instead, was smirking. And both of them gazed over to Yami who was know looking at her brother with a desperate expression. "It's a long story Yami-chan, and a sad one. Are you sure that you want to hear it?"

She nodded almost immediately, whatever it were the reason she wanted to know. "Please Nichan! I've to understand why!"

The Uzumaki boy sighed and eventually he begun with the story. He told her everything about that fateful night, the way the Kyuubi attacked Konoha and the desicion of the Yondaime. Also, Naruto told her about their real parents. Kushina Uzumaki and Minato Namikaze.

"I-is that true...?", she asked silently, her head lowered. Naruto couldn't notice if she was sad or shocked, but her voice seemed pretty sad.

Immediately, Naruto hugged her. With his little hands, the boy grabbed her head gently and put it on his chest. Before she could say something, he began to stroke her hair softly. "Yami-chan... you can't blame Ra-chan for what she did that night. You know that she saved you from that disease"

Surprisingly she didn't cried. "I-I suppose that I'd have to thank her", Yami said returning the hug.

"Bah, this is boring", Kyuubi interrupted crossing her arms under her breasts. "I'm pretty sure you two aren't here to just hug each other, no?"

Yami released the hug and looked pretty annoyed at the beautiful girl. "Why you-!"

"She's right Yami-chan", Naruto held his hand in front of his sister for a second to interrupt her. When she nodded, he looked at the Kyuubi. "I'm here to ask for your help"

Suddenly, Kyuubi seemed amused. "Oh? do you need my help?", she said but it sounded more like that she was mocking at him. "And I thought you were here to meet the most powerful bijuu"

Yami's eye twitched in annoyance as she saw her sigh. "Shut up you- you-!"

"Don't say that Yami-chan. You know is not correct to insult", he sighed in defeat. Talking with the Kyuubi was the most difficult thing he'd done. Not even Ra was so teasingly with him. Oh well, if she wanted persuation, she would have it. "By the way you're talking right now, I suppose you want something in exchange"

The Kyuubi looked at the boy with a smirk on her lips. Inwardly, she was thinking in how he would look in a few years with the proper training. It was almost a pity that Minato sealed her inside Yami and not inside Naruto. She could had have lots of fun with him, "Well, you're a smart kid, aren't you?. The fact is that I know what you are going to ask me and that would require all of my effort"

"Talk Kyuubi. What do you want from me?", Naruto asked not really patient with the matter.

When the girl seemed to be looking at him with a smirk, Yami used that opportunity to ask something to her brother. "Nichan, what are you asking to her?"

Naruto turned his head slightly to one side to look at his sister. Her big violet eyes focused directly into his', "Training for you, of course!"

'Well Naruto-sama, this is where our training begins', Ra announced, receiving a jump of excitement from Naruto. 'First of all, do you know what chakra is?'

'Hmm...', the boy put a hand under his chin and began to think for a moment. He was sure that he read it in a book once but he didn't pay much attention. 'I'm not sure, can you explain me?'

'It'll be a pleasure. Okay then, Chakra is essential to even the most basic technique; it is the moulding of the physical energy, present in every cell of the body and the spiritual energy gained from the mind. If you mould it, it can be channelled through the chakra circulatory system to any of the 361 chakra points in the body'

In that moment of the explanation, the realization hit the boy's mind. 'Ah! I remember the last part now!. It said that if you use some sort of method, like hand seals, the chakra can be controlled and manipulated to create something amazing!'

'It's a way to say it', Ra giggled inside his mind and Naruto blushed just to hear her laugh. It was calm and soft yet wonderful. 'That's what we'll be doing first. At the begining I'll show you how to control your chakra perfectly. Then, I'll show you a form of Taijutsu that I've mastered over the years. Finally, but not less important, we'll find out which nature's affinity your body is and you'll learn lots of Ninjutsu and Kenjutsu'

Naruto's excitement reached its limits and he began to throw his fists into the air. 'Yatta! so, what we're going to do first?'

Ra giggled shortly and then cleared her throat. 'Well, first. I need you to form the Ram seal. Do you know about hand seals right?'

The boy snorted, 'Of course I do Ra-chan! To form hand seals quickly is my speciality!'

Although he wanted to impress the dragon, he said the truth. For over a year he had practiced how to make hand seals at full speed. That way, he was sure he could made cool jutsus in no time.

Shaking his head out of thoughts, he formed the Ram seal with both hands perfectly. He stood there, awaiting more instructions. 'Okay now, I need you to think in what your chakra is. Imagine your energy flowing through your body and try to calm down your heart. Then, imagine that you expulse it all from your body. Naruto, I want you to listen to me. When you manage to do this, you'll feel amazing. I need you to focus on my voice and stop whenever I ask you to. If you don't, then somebody could notice your chakra and it will came to investigate'

'I understand', Naruto thought almost immediately. He was sure that any ninja or not that find him would ask him why he was there, in the only training ground that wasn't ocuppied by any team. Besides that, everybody knew that he wasn't an student at the Academy yet and that will bring a lot of questions about who show him how to do that. 'Here I go Ra-chan'

After that, he closed his eyes and held the hand seal formed. He imagined what Ra asked him to, and found quickly a gold energy that was glowing around him. Naruto didn't opened his eyes, but he could feel a pure yet powerful energy surrounding his body. It felt like he could do anything, break rocks or trees, ran at the speed of the sound and even fly.

For a moment, he forgot about what the Kyuubi said to him inside Yami's mind.

'I'll train your sister, but in a few years you'll have to pay me for my services', Kyuubi said biting her lower lip with lust.

Naruto looked at Yami who seemed pretty unsure of what to do. Remembering what Ra said, he nodded to the bijuu. 'I'll do whatever you ask'

When Kyuubi giggled evilly, he someway felt that he was going to regret what he said. Oh well, everything for his little sister.

'Though, I'll ask for one thing first', she then pointed to Naruto. 'Neither you nor that dragon can interfere with out training. Also, you can't see your little sister during our training or I'll refuse to teach her anymore'

At that Naruto paled slightly, but accepted anyway. After that, both siblings were out of the mindscape.

Naruto continued his training, more and more forgetting about where he was and what he was doing. He felt so powerful that he didn't wanted to leave it. But soon, the voice of Ra brought him to the reality. 'Naruto-sama! stop!'

Opening his eyes, the concentration faded almost immediately and the chakra returned to his body. Blinking, he begun to feel weak. In fact he felt like always, but it was the effect of channelizing his own chakra through his body. 'Phew. That was a close one!'

Ra sighed in relief, she asked him to stop for a few times but he didn't. Still, in the end, she managed to force her chakra through his mind to make him react. 'Pretty close. But now, I'm glad you finally stopped. Who knows what could have happened if someone detected your power'

Naruto scratched the back of his head with shame and grinned. Even if she was inside his mind, Ra noticed his expression and giggled. 'What are we going to do now?'

'Well Naruto-sama. After completing that part of the training, I'll teach you how to channelize your chakra to different parts of your body'

And with a scream of excitement of Naruto the training began. It took him a few years, ignoring the Academy for the first year until he was six years old and he and his sister joined it. What both didn't knew what that being in the Academy didn't meant anything to Kyuubi or Ra, because these two had greater plans for both siblings.

Yes, their training was far from complete.

And that's all Ladies and Gents. Again, I apologize if this took me so long to update, but at last I could get out of the homework to write this chapter.

So what do you think about it? I know it's a bit boring and confusing, but this will get better and better.

Again: I left a poll in my profile, so you can vote for the dimension idea. Anyway, the options are Rosario + Vampire, Highschool DxD or Highschool of the Dead. Of course, this is a Yu gi oh and Naruto crossover so he'd go to that place first or so I think.

As always, try to write good reviews. Flamers will be dutifully ignored. Well Ja Ne!
