I do not own Naruto.

'You're sure that this is a gateway to hell?'

'Yes, now go through it servant.'

'Since when is a gateway to hell surrounded by flowers? Better question why a rabbits coming out of it?'

'The flowers are a disguise and the rabbits are guards.'

'Okay disguising it makes sense I guess, but why rabbits? Why not swarms of killer demonic bees that eat flesh and can kill with one sting?'

'Rabbits have proven to be scarier and more vicious guards than any other creature that naturally exists on a universal plane with humans.'

'Really?'

'Yes, now go into the damned cave!'

Walking towards the not so ominous cave surrounded by flowers with some rabbits hanging around the entrance Naruto stops after only a few steps. 'If the rabbits are guards then won't they attack me?'

'Damn I was hoping you wouldn't catch on and I'd get to see you lose a fight to some rabbits. To get through just let your demonic energies flow freely. The guards have to allow any demonic being free passage into hell. Getting out however will almost always require a fight.'

Removing the many seal covered articles of clothing he is wearing Naruto lets all the inhuman energy flowing through him surround himself in a massive cloud of energy. After storing the excess clothing in on of the many scrolls he carries for similar purposes Naruto then begins to walk towards what the Kyuubi claims is a gateway to hell clad only in his standard ninja attire. He however stops as the rabbits sense his presence and turn to stare at him. 'Is that normal?'

'No clue half-demons usually try to avoid hell so I've never seen one try just walking through a gateway. Don't worry though. It's only once they break out their weapons or jump at you that you should worry.'

'Gee thanks Kyuubi you're such a help.'

'You're the servant I'm the demon lord, I don't have to help you at all so be grateful I'm doing this much. I could just have let you be run of Konoha and trained you while you run around in the wilds of the Shinobi Nations. Instead I'm being generous and letting you keep the illusion of being a human ninja, and showing you to hell where you can train your abilities to their fullest.'

Conceding to the fox's point and deciding that he had pissed him off enough for now Naruto walked past the rabbits and into the cave without being harmed. Inside the cave however he encountered a problem in the form of a giant flaming cat blocking off the rest of the cave. "Umm hello Nibi."

"Who are you? Oh it's Kyuubi's new servant! Why are you here?"

"I'm going to hell to train myself at Kyuubi's request."

'Let me have control for a moment I wish to speak with the nibi.'

'Fine, but try to keep it short I don't want to be forced into fox form before I even get to hell.'

As Naruto turned of control of his body to the Kyuubi the only noticeable changes were the drastic increase in body temperature, and eyes changing color to blood red. "Hello Nibi. Why are you playing guard at this gate?"

"I'm making sure no humans take it over and use it for their own purposes."

"How and why would humans do that?"

"I am unsure of the how, but it likely involves ninja. The why is easy, power. While we were sealed a human apparently took over at least one of the gates and has used it to create an army of controlled demons and resurrected humans."

"Must have been one of the gates for damned human souls. All the others lead into demon territories or wastelands. Oh well I doubt any human could control and demon worth the name. Why haven't you just send some of your subjects to guard the gate from the other side. It is functionally a bottle neck so it would be easier to defend against a human invasion from the hell side anyway."

"Well that's because I no longer have subjects."

"What you got overthrown while you were gone for a few centuries?"

"No, we all got overthrown."

"What! Who was foolish enough to take over my territory!"

"No idea, all I could find out about the situation is that there were three of them and they split up the bijuu lords territories between them. They apparently are either very powerful or the have found something to boost their power because when the others went to reclaim their territory the were destroyed."

"Since we left someone has become strong enough to defeat multiple bijuu lords while outnumbered? Impressive. Once my servant here is trained I shall have to speak with these upstarts. Would you care to join us for awhile Nibi? I'm sure we could work your restoration to power into our plans."

"No I'm must stay here to prevent whichever idiotic human is messing with the order of this plane from wrecking it further."

"Very well. Now if you could move aside so that my servant may pass."

Regaining control of himself and seeing that the Nibi had stepped aside enough for him to get by Naruto thanked her before going into the gateway that formed the back wall of the cave.

On the other side of the gateway Naruto found himself on a platform raised high above the surroundings. Looking out at the surroundings he was a bit disappointed. 'It is a massive wasteland. Aren't there supposed to be demons roaming around?'

'Not here. There aren't really compass directions here in hell, but maps are drawn with the punishment areas for damned human souls on the bottom and the most powerful demon's territory at the top. This wasteland is the border between what was Shukaku's territory and the human punishment areas. No demon come here unless they have to and even then it is usually just to pass through. There are of course exceptions. A few demons actually live out here, but mostly if you want to encounter a demon that could actually be considered such by one of your ninja you need to head towards the demonic north. Not that any of that matters to you right now since until you gain at least basic control over all you full demon abilities I'm not letting you leave these wastelands. After all here there is almost nothing to interfere with your training. There is no weather out here not caused by demons, the temperature never changes on its own, and it is almost completely unpopulated. Now go find somewhere to live while undergoing your training. Just keep in mind you will be a fox most of the time we are out here.'

Thinking to himself Naruto considers the situation, 'Well this sucks. Better hurry before I lose my hands.' Rushing off into the near desert conditions surrounding him Naruto begins his search for a water source to set up camp by. After what seemed like hours of searching Naruto realized two important things. One, this was a useless method of searching. Two, the fox was laughing at him which meant he had missed something obvious. Thinking about the situation for awhile Naruto realized he could set up camp anywhere since he could just condense the air to get water if necessary and that he had food stored in his scrolls for quite awhile. Upon realizing this Naruto unsealed all the camping supplies he had that would be usable in fox form and he set the food scrolls down unrolled in his tent. 'Hey fox when will this transformation take place?'

'Hmm? Oh that will happen right about… now.'

Naruto collapsed as Kyuubi finished his sentence and began screaming, whether he was screaming in pain, fury, or what was uncertain. It was however very, very, loud and loaded with power. What few demons and other creatures heard him made sure to stay as far away from the powerful roar they heard. If they knew what they one causing it looked like they would have made sure to leave the wastes entirely. For almost as soon as it started it was over. Naruto had changed from a human like half-demon into a slightly larger than normal fox with silvery-white fur, blue eyes with an icy luster, and one tail. 'You could've given me a little more warning! That hurt damn it!'

'True but it was quite amusing to me.'

'Damned bastard fox demon lord can't even bother warning his servant that he will be suffering unimaginable amounts of pain. Why just because he finds he amusing. I'm going to skin him alive if I ever find a way to get him out of there.'

'If you are quite done bitching about a little pain it is time for you to learn how to be a demon.'

'That was a little pain?! I'm doing to kill you, you fucking fox bastard!'

'Yes it was now shut up servant so your instruction, and more pain, can begin.'

'I hate you.'

Naruto and managed the basics of moving and fighting in a fox body, and now Kyuubi was trying to teach him how to fight like a demon fox.

'Gather pure energy in your tail, condense it into a ball at the tip, bring the ball to your mouth, eat it, add some more energy to it and make it unstable, then release it from your mouth at a target before it blows up.'

Naruto followed the instructions perfectly until it came time to release the energy. As he opened his mouth to release it the energy became too unstable and the attack blew up just as it left his mouth.

'You're supposed to release it before it blows up!'

'I didn't do it on purpose!'

'Try again!'

Fox-Naruto was running around and jumping through the air with a thin wall of ice floating in front of him when Kyuubi woke up from a nap to check on Naruto's progress. 'What the hell are you doing? You're supposed to be trying to suppress your demonic energies.'

'I am doing that. I'm just trying to create a new technique at the same time.'

'If you were suppressing your power correctly you wouldn't be able to manipulate ice like that servant now get back to the exercises I told you to do.'

'True but this technique will require me to maintain a constantly low and always equal amount of energy while in use. If I can do this technique all it would take to properly suppress my energy would be to take it to an even lower level than the technique uses.'

'Fine you can continue, but if you don't have results from it in a few days you go back to my methods.'

'Fine.'

Naruto was at his camp for his final bit of training in the wastelands.

'Now suppress your power as far as you can. Separate it into your elemental energies, your pure demonic energy, and your raw energy. Bottle up at least half your elemental energy and all of your pure demonic energy. Mix the elemental energy leftover with your raw energy. Remember the feel of this energy this is the youki your human form will now use like chakra. Now let the youki flood your body, but don't let it mix with the contained energies. They'll need to stay locked away until you want to revert to demon form. Got it?'

'Yeah, now here goes.' Following the demon lord's instructions Naruto managed to successfully return to human form. Unfortunately his ensuing joy caused him to release his contained energies and in a burst of power he changed back into a fox.

'Looks like we'll be waiting until you can maintain human form before we start investigating who took over my lands.'

'When can I return to the human world.'

'When I'm done with my business here in hell.'

'If it is longer than two years I'm going back to the human world either way, and you'll just have to finish your business in a few decades.'

'That is agreeable servant.'

'Cool now let's see if I can hold onto human form this time.'

Walking along the streets of the ruined city Naruto conversed with his tenant, boss, and instructor about the situation. 'So this used to be the main city of Shukaku's territory?'

'Yeah, but really it was just a collection of bars and brothels with a castle in the center. The sad thing is this was the third most populated city in the demon territories. Only Nibi's capital and the Orochi's fortress were larger.'

'What were they like?'

'Nibi's capital was like a human one. It had residences, businesses, a castle, and a military base. Even though she was amongst the weakest of the bijuu she has held her position the longest aside from myself. This is because what she lacked in power she made up for by having the only truly trained demonic army in all of hell. The only other group that comes close to being a properly trained army of demonic soldiers would be the guards for the damned human souls, but they are so weak nobody really cares about them. The Orochi's fortress is a hellhole. It is only called a fortress because of all the traps and automated defenses built in. It is populated by Orochi, his guards, demon engineers who design and maintain the defenses, and demonic slaves who are forced to do all the menial jobs in the place. Orochi is quite possibly the most paranoid being in existence, and his fortress is proof of this.'

'Wow. So should I go to Nibi's capital and see if I can dig up any information on the beings that overthrew you and your cohorts while you were all sealed away?'

'No you need to become more skilled at fighting with your new abilities before we go investigating this mess. A group of minor demon lords ruled over a sort of neutral ground when I was here last. Go pick a fight with them. If you can win without calling on my power or my mark then we can go investigate.'

'How strong are they?'

'They used force to keep their territory neutral.'

'Any suggestions for how to go about this?'

'Kill them all and make sure they're dead before moving on to the next one.'

'This is going to hurt.'

'Of course.'

"Great as if it wasn't enough that I have to face a group of demons capable of holding off the bijuu, I have to break into a guarded castle to do it.'

Unable to find a way to sneak into the demons' castle Naruto decided the guards might be a good warm-up and shifted into full demon form to attack them. Rushing at the two guards by the door Naruto killed one easily by running it through with an ice-coated tail. The second one lived long enough to call for more guards before it was hit by several needles of ice in the face turning it's cry for help into a cry of pain. Naruto finished it off by ripping out it's throat with his claws. Before he could break into the castle he was surrounded by six more guards.

Instead of calling out for him to surrender like human guards would the demons attacked en masse with a variety of fireballs, lightening bolts, and swords. Naruto used his wind powers to send the two charging him with swords into the fireballs, and created a small shield of ice to block the lightening. Seeing their attacks fail the surviving demons moved in for hand-to-hand combat with their powers amplifying them.

Deciding his warm-up was over Naruto created a horizontal blade of wind which he used to cut his attackers in half. Shifting back into human-form he broke down the door and walked into the castle. He was greeted by a small green demon wielding a stick.

"Are you guest or intruder? "

"Intruder. Who are you?"

"Who am I? Who are you? Why are you here?"

"I don't know who you are. I'm Uzumaki Naruto. I'm here to fight the rulers of this castle."

"Then aren't you a guest? Why do you not know of me? Why come challenge someone without knowing their identity?"

"So you are one of the rulers of this castle?"

"Am I one of this castle's lords? If I am would I be Johin? Will we fight?"

"Well if you aren't one of the demons that rule here prepare to fight anyway!"

As Naruto charged the diminutive demon he summoned Hie from a scroll to fight with. The demon in turn encased most of his stick in stone from the castle walls. The stone took the shape of a double-edged blade following the shape of the stick. Naruto's strike hit the stone blade but failed to accomplished anything except make the demon give him a fang filled grin. Naruto was then knocked across the chamber when the demon pushed back against Hie. Realizing that the demon was far superior to him in strength that meant he would need to either be faster than it or fight it at a distance if he wanted to win.

Seeing his adversary shift into the form of a kitsune Johin decided to start being serious. After all kitsune are naturally faster than humans and combining that with the boost in abilities that comes with being in one's true form this Naruto's speed might be enough to strike him before he could defend against it. And from what he had seen of the fight at the gate the boy could form wind blades that could pierce any armor he tried to use. He knew he needed to get in close with this kitsune and keep him from using his wind powers. When the fox started charging him he started trying to drop sections of the ceiling on it, but they were all dodged easily. As the fox closed to striking distance he tried to stab it with a quick thrust, but when his stone blade neared it's target the fox disappeared. Realizing what had happened Johin brought his sword down onto the ground instead of pulling it back into a guard position.

After putting on a burst of demonically enhanced speed to avoided the sword approaching his face and get behind his foe Naruto lunged forward to bite at the back of the demons neck. His efforts were thwarted when a pillar of rock erupted from the ground under him. Rolling off the pillar before it crashed into the ceiling Naruto used his control over ice to form a shield before him as well as using it to sharpen his fangs and claws. He then used his control over wind to launch himself Johin. The distance between them closed to fast for Johin to get out of the way, but he managed to bring his sword around for a strike. The ice shield shattered from the strike, but it managed to prevent the blade from killing Naruto. However it only did so by deflecting the blow downwards changing it from a head-cleaving blow to a chest splitting one. Naruto used his ice covered claws to take off Johin's arms and his fangs to rip out his throat. Johin collapsed to the ground as his stone blade broke apart into a stick and some rocks with his death. Naruto landed unsteadily on his feet with blood dripping from his jaws, blood soaking the fur of his paws, and his own blood leaking from a gash across his chest. He made it two steps to the next door before he collapsed from blood lose.

As Naruto lost consciousness as three hazy figures surrounded him and began talking, "What should we do with this one?"

"He is a threat. We need to kill him."

"He could be fun. We haven't had a real challenge since those new guys took over. They keep killing anyone who has potential or who is near them in power. We should fix him up and let him take on the rest of us."

"Yes he could be interesting, but if we need to patch him up after every fight against us it would take far too long and be boring."

"Then let's kill him now. Or we could have fun while killing him. Send him after those weaklings and see how they do against him."

"That idea has merit. However he seems rather inexperienced."

"We'll train him then we can all fight him. Then when we win we fix him up again and set him loose on them."

"That seems like a lot of effort into so little fun. Besides what if he wins after our training?"

"Well then let's just kill him now. Standing here talking is more boring then watching the weaklings fight amongst themselves."

"Very well." After that Naruto finally lost consciousness.
