Chapter 2: Power of darkness

I do not own Naruto or this idea. The idea belongs to kagedoragon

"Ugh, what…"

"Where am I?" The young ninja slowly got up from where he was laying. "What the? Wasn't I just in a forest? How the hell did I get in a sewer?" Looking around, Naruto started walking through damp halls, wondering why he wasn't wet from laying in the two-inch deep water. After wandering for what seemed like hours, he came across a strange symbol. It was a circle full of lines that swirled to the center with a fox head."What is this?"

Without warning the mark began glowing a dark purple, bathing the area in an eerie feel. The symbol starts to beat like a heart. Feeling uneasy, Naruto decided that he should find a way out. He starts moving at a fast pace, looking for an exit.

"Come here, young one." The voice came out of nowhere, startling the Gennin. Deciding to follow the voice, Naruto hoped it would be willing to help him. Soon, he came to a large opening in the wall, almost as if it was meant for a giant. Going in, Naruto saw an enormous gate, which upon closer inspection, had a small piece of paper with the kanji for Seal on it.

"Well, now that you're here, we can begin." As the voice spoke a large figure appeared out of the darkness.

"What the… Wait, you're the Kyuubi!" Indeed the being was a blood-red fox, with nine tails waving lazily behind it.

"Smart boy. Now that that's established, let me tell that your chakra was sealed by that Hebi-teme. And because of that, the chakra that the Yondaime Hokage's seal transferred from me to you is running amuck in your body, changing it. Fortunately for you, your body has adapted to my power, otherwise you'd already be dead. If you let me, I can use the chakra to give you a Kekkei Genkai that will allow you to absorb demonic energy without having to worry about it harming you. However, I do want something in return. Freedom."

"I'm not letting you go so you can attack the village if that's what you want, Kyuubi-teme."

"No, no, I simply want to be able to stretch my legs. I would still be bound to you, and the Kekkei Genkai I plan on giving you will allow you to keep me from hurting anyone."

Glaring suspiciously at the demon, Naruto asks, "What does the Kekkei Genkai do then."

"It allows you to absorb demonic chakra, as well as the demons themselves, so long as they are weaker than you, you will be able to incorporate their power and skills into your own. You will have the ability to summon them in three different forms: demon, human, and weapon. There is a drawback to this, as you will lose access to their chakra when summoned. I know you don't like to be given power for nothing, so you will have to work to control their powers, except for passive abilities such as enhanced senses.

"You will also be able to partially infuse your body with a demon's chakra to gain temporary physical benefits and change in appearance. The changes will be similar to body of the demon you're infusing, though they'll only be minor ones. There are a few more things, but there are demons approaching your location. So, do you accept?"

Naruto, who was a little surprised that the Kyuubi would be willing to give him something like that, thought it over for a few seconds, before making a choice.

"Alright, I'll agree to that, but what do you get out of it?"

"Well, for one thing, I get a little more company around here, seeing as your mind is a little empty right now. Plus seeing as you've technically already absorbed me, you can summon me as well. Now then, I'll activate the Kekkei Genkai as you're waking up, so try it out on those low class demons."

"Wait, what was that weird symbol I saw before?"

"We can discuss that later, for now go kick ass." The surrounding area began to fade out as the fox spoke again, "Oh, one last thing. I'm a girl." The vixen smirked at the astonished on Naruto's face as he began to awake.

(Forest of Death)

Naruto's eyes shot open as he sat up. Looking around, he noticed the ground around him looked burnt and dead. *Snap* Naruto spun around and saw what had made the noise. 'Damn'

The creatures were clearly not something that could be considered normal. The first was on four legs, standing almost 6 feet at the shoulder. It had a feline appearance with a long tail. The beast was covered in purple fur with lavender stripes on the end of its tail, its legs, and on its chest. The fur on its lower legs, ears, and cheeks was white with a red tuft on the tip of the tail. Its ears were long, and its eyes were green and surrounded by black markings. Looking it over, Naruto saw that the creature had opposable thumbs on its front paws.

The second was like a mutated crow. If a crow had a wing span of sixteen feet and two heads. It's cries make unbearable noises, while flapping it wings where entice batches of feathers were missing. The third was what appeared to be a very long dog that floated in the air. It body was over twenty feet long and covered in white fur, it's black maul in a sneering grin and glowing re eyes

'Hmm, a cat, a bird, and a dog demon.'

'Kyuubi, is that you?'

'Yes, Naruto, it's me. Now, be careful. Cat demons tend to prefer speed in battle. They also like to play with their prey. Try to finish it first, the bird is called a Ni-hitsu kiai. They enjoy disorientating their enemy so keep focused and the dog is an Inugumi who prefers to sit back and use long ranged fire shots.'

"Alright then, let's get this started."

Naruto settled into a Taijutsu stance and prepared to fight. The beast opened its mouth, revealing a green tongue, and fired what appeared to be a blast of black lightning at Naruto. Naruto jumped to the side, barely avoiding the attack. Using the Kage Bunshin no Jutsu, he sent the clones to attack up close. Just as the clones reached the demon, its mane whipped around and grabbed them.

"Oh come on. It can use its hair as a weapon! That's so not fair!" The clones used their kunai to try to cut the hair, but it proved futile as the hair shifted out of the way and then pierced through them.

Meanwhile, another clone was wrapping a large number of explosive tags into a ball. Running straight at the cat's head, the clone allowed itself to get caught to get closer. When the cat pulled it in to look at the clone, it shoved the tags into the demon's face just as they ignited.

*Booom*

Naruto and his remaining clones watched carefully for any sign of the demon. As the smoke began to clear, Naruto saw that the cat demon was wavering. As its face was revealed, Naruto saw that the fur on its face had been burnt off, and its jaw had been broken from the power of the explosion. It began stumbling as it had lost its coordination.

"Naruto, it's lost enough power, do it now! The jutsu is Demon Assimilation Jutsu, and the handseals are Hitsuji, Ushi, Nezumi, and Ryu. Once you do those, put your palm on it's forehead."

"Right. Hitsuji, Ushi, Nezumi, Ryu, Demon Assimilation Jutsu!" Naruto rushed up and slammed his right hand onto the demon's forehead. With a flash of light a vortex appeared in Naruto's palm and began sucking in the demon. Naruto felt a surge of chakra rushing through his body, and soon felt the presence of the new demon's mind. Naruto sighed and turned around, only to freeze as the Ni-hitsu kiai began to scream cause the world around Naruto to blur as the inugumi send a horde of small fire balls at him.

"Ah fuck."

'I agree."

The fight scene may be a little short, but that's because the Forest of Death only has low-level with more passive based abilities. The cat demon was at most a low C-class demon, easily defeated by anyone with enough skills. The Bijuu are much stronger, being from high S-class to SSS-class. The Kyuubi is a SSS-class demon, so you can see that she is much stronger than a C-class demon.
