Summary: What are the consequences of the Yondaime's deal with the devil? How will it turn out for poor Naruto and will he honour the power of semi-divine sacrifice. X-over with demigod

Legal disclaimer: I don't own any of the following ideas, themes, characters etc...

"Hokage-sama! Morino-san is here and he says it's important" the secretary said bowing to the blonde haired hokage, tripping over herself in awe of the strongest ninja in konoha. 'Phh this is going to be troublesome I can feel it' the hokage thought channelling the attitude of the Nara clan "send him in quickly I need to get back to kushina she's gonna kill me if I'm late".

A tall man with a bandana wrapped neatly across his head walked in, he bowed before the hokage respectfully before announcing the reason for his interruption. "Hokage-sama, we have found something with the prisoner coming in from the hidden rain village, I think you need to see this."

He took out a black book from his trench coat, the book was torn and ragged at the spine but somehow was still whole. 'Use us' the book seemed to say, trying to dominate the Yondaime. 'You will need us, we can sense misery and despair making its way over to your pathetic village'.

"Ibiki-san, what the hell is that thing? And why have you brought it here?" he demanded.

"Well we're not sure exactly and that's the problem it keeps whispering messages of power to anyone who approaches it, from what we sense it seems to be trying to convince someone to release a prisoner contained inside."

"What makes things worse is that we didn't manage to get any information from the individual who owned it, he died from a severe infection – one we've never seen before, and even Tsunade-hime couldn't combat it".

This was perhaps the biggest surprise after all a talking book is one thing but Tsunade, the greatest medic alive, hadn't been able to cure it ,diseases should be baby play to a medic of her calibre.

Crash! An ANBU agent made his way past the doors flinging them open "Hokage-sama, scouts have reported a great monstrosity heading in this direction; it's destroying everything in its way. Danzou is demanding action before it's too late".

'Best take care of this problem first' thought Minato. "Give me the book I'll deal with it later for now I'll just seal it in this piece of paper while Ibiki handed over the book. "Now what's this about a monstrosity? "The hokage demanded of the scout.

'Minato if you don't get here soon I'm gonna castrate you, you ungrateful son of a bitch.'"Come on push" said a medic-nin in white clothing surrounded by nurses soothing the soon to be mother. "I am pushing what does it looks like I'm doing! "

"Am I too late?" a blonde head said sticking in the room. He was answered with a shirt pull which sent him tumbling inside "no you got here just in time"; the med-nin said "now you go tell her to push". "AHHH! I swear to god minato the only thing you're getting pleasure from anymore is your hand" screeched the pregnant woman."Come on baby, you can do it" comforted minato lovingly.

(later)

"WAHHH!" a wail was released from the new born baby. "Would you look at that Kushina, we have a son!" sniffed the Yondaime. ..."Kushina..." the hokage started to worry due to the lack of response from his usually energetic wife.

"Don't worry hokage-sama she's just sleeping the birth took a lot out of her" the medic-nin said trying to console Minato.

"Have you decided on a name yet?"Asked the medic-nin

"yeah, we decided on Naruto in memory of Kushina's grandfather".

"Hokage-sama! The beast is only a day away from our village. What should we do?" A nervous ninja announced to the hokage. "Just get Sarutobi-sama and Jiraiya-sensei to my office pronto."

'What a Long weekend' thought Minato 'at least Naruto's birth went without a problem'. 'How on earth am I going to combat a seventy foot monster which heals within seconds?' sighed Minato.

'Use us! We can deal with that dirty beast, just release us! We swear to serve konoha and its ruler.' The thought penetrated the Yondaime's mind ensnaring him. He reached out to the seal, with the intent of releasing the book, when it was snatched by a white blur. "Interrupting are we?" Jiraiya asked smiling and standing next to the Sandaime.

"Thank god you're here Sensei, I need a way to kill the beast without using the shiki fuin, I can't leave Naruto without a father" pleaded the Yondaime.

"Well, all three of us can think of a problem soon enough" Jiraiya told Minato.

"I already have found a way, just give me that piece of paper and that's an order from your hokage" demanded the blonde.

"Ooo touchy, what's in there anyway?" asked Jiraiya handing over the seal, staring with curiosity at it. Minato didn't answer but instead bit on his thumb and smeared some on the paper. The book dropped on the table and now seemed to be screaming at all three "Yes Use us! We beg for release, we swear to serve the ruler of Konoha till his dying breath, just drop some blood on this book!"

The three elite ninja were rolling in pain on the floor, the book screaming in their minds. Minato managed to crawl over and smear some blood on the front cover. 'Ahhh. It is over you shall have your vessel and its power shall be incomparable. You have chosen wisely.' The book told the Yondaime.

"What the hell did you just do?" asked Jiraiya of his student, his hand surrounding Minato's neck, his head still pounding from the screaming.

"I did what I thought was necessary, but it seems that I'll have to use the shiki fuin anyway...useless book" muttered the blonde, choking from his sensei's strength.

He dropped to the floor as Jiraiya removed his hand. "You aren't a foolish genin anymore minato. You're the Hokage, act like it. How do you know that the power promised to you isn't just a ruse to kill you?"

"I could feel its sincerity Sensei, I think it was just locked up and wanted to be free, I felt the power of its declaration- it shouldn't harm anyone from Konoha unless it serves the ruler to do so"

"Don't fret Jiraiya I also felt it and I can also remember many instances where, despite being a sannin, you also acted like a foolish genin, so do try to take your own advice" the Sandaime said behind the cloud of smoke coming from his pipe. Jiraiya just grumbled something about stupid, back-stabbing senseis, while minato sniggered.

----------------------------------------------------------------------------------------------------------------------------------

'This is it' thought Minato standing on the back of a huge toad making his way to the kyubi, one arm wrapped around a bundle of blankets.

The ninjas fighting the kyubi, seeing his figure and the giant figure of gamabunta, were spurned on and started unleashing a multitude of elemental dragons, rockets and the like at the 'unstoppable' force in front of them.

'I hope you can forgive me son, for what I am doing is surely the worst of sins, I just hope Jiraiya and Kushina raise you properly' thought the yellow flash, finishing the seals to the shiki fuin "SEAL" shouted the Hokage, a blue stream of chakra flowed out of him and formed a portal, out of which a colossal river of pure black chakra came rushing at the kyubi.

Surprisingly another stream of chakra seemed to emanate from Naruto this one also being black but significantly smaller than the other. Both chakras wrapped round the Kyubi in a vortex and slowly began to draw out red chakra.

The effect was instantly seen as all the ninja techniques started to affect the kyubi and the damage didn't fade away."The beast isn't healing!" exclaimed an anxious ninja "Let's finish it off".

The kyubi having both its chakra being sucked out and its physical body attacked seemed to be dying; the ninja spurned on began to spew out even more techniques in righteous justice for their fallen comrades.

The black chakra pulsing with the kyubi's chakra suddenly shot to Naruto and surrounded his skin, before slowly being absorbed into him. 'Good luck my son, I fear you shall need it' thought Minato as the now smaller black chakra shot to him...

The Sandaime moved across the battlefield which was now still, the huge army of ninja still in disbelief over the defeat of the kyubi. "Wahhh!" a demoniac wail pierced the silence.

Sarutobi quickly moved to where Naruto laid, he covered up a look of disgust and revulsion as he covered the infant. 'No one can now about this, they would only blame it even more'.

"Jiraiya" Shouted the aged man "get over here now!" "Sensei did Minato seal the kyubi?"

"yes but there's a slight complication..."Jiraiya having only now noticed the bundle quickly moved to take the bundle from the Sandaime but stopped as the old man shook his head. "prepare yourself for what you're going to see it isn't anything I think you've ever seen before"

"come on sensei what could be so bad the kyubi is gone and with it the possibility of the destruction of the village" however he stopped suddenly as the Sandaime uncovered the infant, if it could still be called that.

Naruto was more of a beast than child, the most noticeable differences being that his skeleton was now on the outside and covered orange skin which seemed to be rotting and healing constantly with pools of green forming around wounds. His teeth dripped with acidic saliva and his entire body was covered in sharp spikes. He also seemed to be crawling more naturally than a baby would seem to almost as if he had 4 legs rather than 2.

"This can't be Naruto" pleaded Jiraiya desperate to see his godson in his healthy human state "That isn't even human"

"I fear this is the consequence Naruto must pay for Minato's moment of foolishness, I fear this is the unstoppable power that, that cursed book predicted."

"Kushina won't take this well... Her husband is dead and his legacy has been corrupted and tarnished, "Jiraiya said with worry "let me take him sensei, I can raise him outside of Konoha, where he won't be gaped at. And more importantly where he won't reap destruction"

"...Haven't you heard yet Jiraiya – Kushina passed away earlier this morning, there was a complication with her death. A disease of sorts, similar to the one found among the dead of the caravan which came from hidden rain village last month."

"but Tsunade was here..." "I was told Tsunade tried to cure it but it was caught too late and the disease was too powerful... I'm sorry you had to hear it in this way. I'll leave you with Naruto now, come to my office after you've dealt with her death, You know just as well as I do that what you're proposing is preposterous, we need you as a spymaster you can't be weighed down by an infant. We'll figure something out

". The Sandaime left Naruto with Jiraiya and quickly disappeared from the battle scene with a whirl of leaves.

Jiraiya looked at Naruto taking in a most peculiar sight as Naruto managed to break of one of his ribs and started to gnaw at it as if it were some kind of demonic chew toy.

Jiraiya watched in fascination as a new rib grew from where the old one had been snapped off 'there's no way on earth the villagers are going to be able to handle Naruto especially not after the kyubi. I need to take Naruto away from here –I'm the only one he has left after sensei' the sannin thought as he quickly decided to take his godson elsewhere. 'First we need to see Tsunade-Hime' He thought as he covered up Naruto who was lying in his arms.

By this time Jiraiya began to wonder about how Naruto's covers were still intact when it was clear to see his body was covered in acidic poison that was constantly warring with his innate healing, It was a miracle that Naruto wasn't constantly screaming in pain.

Naruto, as if realising he was at the centre of attention, began to roar softly, Jiraiya looked at him with surprise thinking dimly that it should be no surprise Naruto didn't even have human vocal chords. Moving across the battlefield Jiraiya was suddenly startled as he dropped the bundle in his haste, only to get another shock as Naruto came into his sight swinging by his white hair from atop of his head.

'Little gaki seems to have a natural mastery of balance and acrobatics' he pondered as Naruto had by now made his way to Jiraiya's torso managing to dodge Jiraiya's attempts to catch him.

Kakashi looked on in surprise as the perverted sannin seemed to be having trouble with a black blur moving devilishly quickly around his body. "Jiraiya-sama, need any help?" he inquired snickering as Jiraiya turned redder and redder with embarrassment.

Jiraiya grunted with achievement as he finally caught Naruto, only to appreciate just how bad this could be if Kakashi couldn't deal with Minato death. "Kakashi-kun have you heard, the kyubi has defeated"

"What exactly happened Jiraiya, all we saw was the kyubi suddenly turn mortal?" Kakashi was clearly desperate for answers. His sensei had just disappeared from the battle field within moments of the kyubi's destruction. "Minato-kun sacrificed himself and his child for the sake of the village, we owe our lives entirely to him and his courage" answered Jiraiya deciding a small lie was easier than trying to explain how, despite Naruto containing the Kyubi, he was not the Kyubi itself. Especially with Naruto in the form he was then.

Jiraiya blinked as all he saw was a whirl of leaves signifying Kakashi's abrupt departure, 'Whew! Awkward moment avoided' Jiraiya thought as he moved faster with Naruto who was now hidden deep within Jiraiya's vest.

"Tsunade-hime you've got to see this" Jiraiya shouted bursting into the hospital via the window making way at once for his old partner "NO Jiraiya for the last time I won't look at your""It isn't that Tsunade, I swear, It's deadly serious and needs to be discussed in private" Jiraiya looked around the room nervously as everyone had stopped what they were doing to see the remaining loyal sannin talk.

"It had better be serious Jiraiya or I swear to God..." Tsunade said, trailing off at the end and accentuating her statement by waving her fist at Jiraiya. Jiraiya quickly put up a privacy jutsu around the empty room they had just entered, preventing any of those more curious onlookers from listening in.

"Well..." Tsunade was tapping her foot impatiently staring at Jiraiya for a reason they had moved away from her needing patients. Jiraiya just took out Naruto and watched his old team mates face for some kind of reaction. Tsunade did not realise that the creature in front of her had once been Naruto so instead of further examining it: "what the hell is that thing?" Jiraiya scratched the back of his head in response before telling her of Minato's deal.

"And this is the result" he finished. Tsunade without waiting immediately started examining Naruto before sending Jiraiya for books on large cats and dogs- she had an expertise on human anatomy not that of beasts or animals, for this she would need a lot of references.

(Later that day)

Tsunade had finished her initial analysis of Naruto and had been even more surprised than initially, Naruto was definitely weirder and more freakish on the inside than the outside. She surmised that his muscles had been augmented severely to the point where he wouldn't have trouble in wrestling an 800lb bear despite only being around 50lb.

That was another thing that piqued her interest, Naruto's bone structure had been altered severely so that not only was it on the outside but there was also many smaller bone structures around his vital organs. His bones were also several times stronger and denser than the average humans rivalling that of the Kaguya clan or even surpassing them.

From what she could gather lying in Naruto's blood and being secreted by his cells was an incredibly lethal poison which was so powerful that Naruto's own body couldn't handle it, this was the reason for his skin's appearance.

In fact it was Tsunade's theory that Naruto wouldn't be able to utilise most of his chakra being left to deal with only 10% as the other 90% and all of Kyubi's chakra are being used by his body to combat the effects of the disease.

His small claws and the fangs that draped out of his mouth were connected to glands secreting a much larger and more concentrate dose of this poison.

His vocal glands would never be able to produce human sounds- Naruto would forever more be mute!

"To put it simply Jiraiya, he's the most powerful biological weapon this world has seen. If he could somehow secrete this through the air he would be an unstoppable one man/thing army, the poison is constantly mutating and is acidic enough to dissolve steel within seconds of contact." Tsunade was never known to beat about the bush and she didn't fail to deliver on this occasion with her sharp bluntness cutting into Jiraiya's hope of a peaceful life for Naruto.

'I guess it was too much to hope to raise a normal demonic beats, no I just had to get the most powerful creature. Whoop-di-fucking-doo' thought Jiraiya with dejection.

"Tsunade-Hime I'm going to disappear for a few years with Naruto here, I'm leaving before sensei tries to stop me, please tell him I'll be nearby" he said patting the smooth skull of the curious infant "I guess this is goodbye for now" Jiraiya said jumping through the closest window.

Two thoughts ran through Tsunade's head at that moment; one, why did Jiraiya never use the door and two how on earth was she going to explain this to her sensei!
