Recap

Suddenly Naruto was in the real world and he could see the boot coming down at him again and suddenly he was hit with mind numbing rage and in that moment the darkness covered his limbs and his and formed massive clawed appendages and he lunged digging his massive hand into his attacker's chest.

Naruto sat up quickly before feeling an ache in his back and after moment he began looking around figuring out from the view that he was resting on top of the hokage monument not noticing the dried blood coating his hands and feet.

Naruto got up and took off dismissing the previous night as nothing but a dream unaware of his whiskers glowing and the demon darkness crawling over his legs making him go far faster than any other time in his life but with his new physiology and reflexes he didn't notice just how fast he was moving unknowingly gaining the attention of several ANBU whom began to stalk Naruto.

The new demon finally reached his home and just as he reached the door an ANBU wearing an inu mask tried to chop the boy's neck but the darkness sprung up and covered the area inu intended to strike earning a crackling pop from his hand in response so instead inu quickly made hand seals before tapping the back of Naruto's head before the darkness could cover the area causing Naruto to fall face first into the door.

Kakashi quickly picked up Naruto and body flickered into the hokages tower before speaking "Hokage I have found Naruto although he seems to be different physically at least as when I attempted to knock him a black and purple mass blocked my first strike."

Hiruzen looked at Naruto taking in the sight of Naruto's glowing whiskers before he pulled the boy's eyelid opens and exposed his eyes which had lost the majority of the black coloration in the iris but the purple tinge around the edge remained and the original blue was darkened.

Suddenly Naruto's chakra pulsed his iris became black and purple again and his entire body was coated in the darkness and Kakashi's chakra was forced from him and he shot up.

Large clawed hands formed over Naruto's own and a fox like face began forming over his head as he swiped at the two in the office causing the hidden ANBU to lunge out their blades struck but didn't cut and in fact they bounced off.

Naruto's dark purple eyes swept around the room a look of confusion and anger in them before his eyes landed on the hokage and they gained focus "Old man what is going on?"

Said old man was confused and frozen the constructs on Naruto's body the dark almost black purple felt faintly demonic chakra but mostly human Hiruzen felt it was similar to when Kushina had slightly tapped into the Kyuubi's power tainting the human chakra slightly but not enough to cause a transformation.

Hiruzen came to a conclusion somehow the Kyuubi's chakra had bonded to the uzumaki ability to make chakra constructs but due to said chakra it was actually able to make far more complex structures than chains such as appendages.

"Naruto calm down do you know where you are?" asked the Hokage after a moment the dark purple mass peeled away from Naruto's face exposing the young boy underneath.

Naruto looked around a moment before speaking "I am in your office…how did I get here?" as he spoke the darkness receded until it was just coating his limbs.

The Hokage slowly raised his hands and moved closer to Naruto motioning for the ANBU to back away for now.

"Naruto last night a group of civilians was found slaughtered in an alley way late last night do you know anything about that?" asked Hiruzen a bit of concern creeping into his voice.

Naruto gained a thinking pose before the figurative light bulb went off over his head and with a smile he said "Oh yeah they tried to kill me so I killed them back." Hiruzen's jaw almost dropped at Naruto's open admittance to murder all be it in self-defense.

Several of the ANBU tensed slightly at the boy's tone but the boy didn't move from his spot Naruto looked at Hiruzen and smiled before he spoke "I found out a bit about my family."

Hiruzen raised an eyebrow in confusion before he spoke "What are you talking about Naruto?"

Naruto's dark eyes almost seemed to glow a little as he spoke "I am a demon a real demon not like the wannabe Kyuubi!"

Hiruzen froze as did everyone else in the room "Naruto what are you talking about?" asked Hiruzen nervously making Naruto's smile widen slightly.

"When I was attacked I was pulled into…into a mindscape I think he called it… but any way I meet the Kyuubi and someone from my family." said Naruto.

Hiruzen had now gained a confused look before he spoke "What are you talking about…how could you meet someone inside your mindscape?"

Naruto tilted his head and replied "I am not sure how but he said he bonded his consciousness to his blood so if any of his decedents gained his abilities they would have someone to help them understand the basics of their abilities."

As Naruto finished he brought his hand up and made the giant claws form again making the ANBU tenses before he deformed them.

Hiruzen looked at Naruto whilst putting his original idea about Naruto's transformation on the back burner for the time being.

"Naruto you mean to tell me that your abilities don't come from the Kyuubi…and that you meet the Kyuubi?" asked Hiruzen while staring into the eyes of the young boy trying to tell if he was lying or not.

Naruto nodded "Yes Meliodas said that he was a demon and that this stuff on my body was called the demon darkness and that it was a natural ability of the demon clan's magic…or chakra."

Naruto paused and blinked for a few second before continuing "Yeah he said that chakra was once called magic."
