Hey guys and girls.

Well, it is time for me to bring you a fanfic I have never really thought of doing really.

I've seen the RWBY series but I never really thought of making a fanfic of it. Until now.

Naruto will be a full fledged badass in this one. And ontop of that I've added a slight twist to it.

Much like Blake Belladonna being what she is, Naruto will be something more powerful and more different. So I was thinking. What to make him? And then it hit me. Why not add in a bit of a Devil May Cry flavour? And then it came strong to me.

As well here is the harem list.

Blake Belladonna (Main pairing)
Ruby Rose
Weiss Schnee
Yang Xiao Long
Cinder Fall
Velvet Scarlatina
Velvet Crowe (Tales Of Berseria)
Maya Natsume (Tenjou Tenge)

So enjoy.

Disclaimers: I own nothing.

Chapter 1: The Legacy Of A Devil.

For many years, Naruto could only remember pain. All his body could ever think about was pain. The pain of having everything stripped from him. The pain of not being able to do anything. The pain...of not being strong enough. Ever since he could remember (Which was right from the beginning when it happened), he was considered weak. His family was one of the most prestigeous houses in the Vale. They were warriors. Hunters and huntresses that sought to make their mark everywhere and anywhere in the world. They were revered as a family of mercernaries if you're looking for a dramatic approach. They went where ever the money was good. People paid top bucks to hire them just to rid demons and creatures of Grimm from the world.

But when the time came to produce a new heir to the noble family. Naruto was conceived. He was born on the 10th of October. He would've been born sooner if his mother hadn't gone into a fight with a Grimm and injested a slight bit of the blood spatter that sprayed her face from said Grimm. The blood never harmed her biology in any way. But it did affect the unborn child drastically. So much in fact that when the child was born, his hair turned a pure snow white and his eyes were an ice cold blue.

His parents did everything to distill the fundementals of what it means to make your mark in the world. But, they failed. They failed when he couldn't even do the most basic thing. Call on your power. It wasn't his fault. He found out quite recently that he had Grimm blood flowing through his veins. How he found out was that when he cut himself - by accident mind you - when he was climbing a tree. What he found was that his blood was a more darker shade of red than regular blood. With Grimm being an extremely dark red when he read up on then.

Then the worst came around. His parents gave up on him 4 years after his little sister was born. Naruto was only 8 at the time when she was born. Now she didn't have the Grimm blood in her veins like he did, and she showed even more promise than him. She excelled in everything and even scored a perfect score on everything. Naruto struggled so much due to the constant shunning and scorning that had reared its ugly head for him to see. Even the comparing of him to her. How she was such a genius and a prodigy while he was a waste of oxygen.

But even through all this darkness, there was one candle that Naruto clung to. This candle went by the name of Mito. His grandmother. She never scorned him, never hated him. And never belittled him. She did everything she could to teach him everything she knew while trying to help him in his growing insanity. His little sister had even caught on what was going on between Naruto and Mito and snitched on them. Mito was yelled at and belittled for not training the rightful heir. But Mito didn't care. She continued to train Naruto and constantly tried her best to not show the cracks of hardship from the words of hate directed at her.

But that was when that candle was snuffed out of existance. Mito passed away in her sleep and Naruto was now fully in the darkness. The abuse and neglect worsened ever since and so did his growing insanity. He was nicknamed, The Failure.

One day, Naruto found a Will Mito wrote down, and in the Will was the handing of possession of her weapon. Osiris. A legendary scythe that had high attack powers and was used also to destroy a powerful Grimm, she was handing it over to Naruto. Naruto accepted the weapon but when the family found out they scorned him and beat him, followed by them telling him he's a thief and that he should never take anything that wasn't his. He showed them the Will but they brushed it off by stating that he just forged it as well as Mito's signature.

Naruto was seriously isolated beyond anything in the world. His very being and even his own thoughts were ravaged by the constant voices in his head. Screaming and laughing at him. His insanity was so worse that he would have ice cold showers. So cold that it was like standing naked in the Arctic regions. Just to have some calmness in his mind. But it never worked as the screams would only come back as soon as the water stopped. To ensure he would never get in the way of his little sister, Naruto's parents locked him away in a cell. In the basement that was cold and damp. Not even a shred of light was seen. At least he'd be fed.

Yeah right.

As soon as that door closed, not even a scrap of food came down for him. He was forgotten, he was neglected. He should've known. He should expected this from the start. He was always the outcast. The down trodden. The unspoken of. But as he was thinking on what he was going to do with this feeling of lonliness. Something inside him snapped. And it was this snap. That caused the Grimm blood flowing in his veins to awaken. Naruto's body took a massive transformation. His hair grew longer and more tamed to be shaggy and shoulder length. But still retained a few spikes here and there. His body grew with bones breaking and mending to form a body of 14 years old. But the most noticable change was when his right arm, from the elbow down to the fingertips. Turned to something demonic. From the elbow straight down to the palm on the top of his hand, a blue stream burst forth with the fingers glowing a blue colour with the stream. Red scales shot out and covered the rest of the arm and gave off a malicious vibe to it when its birth was completed.

Above the basement of the house, a party was going on. Now Naruto's parents were the strongest of the main house and were named Kushina and Minato respectively. They were enjoying a nice time outside, a small gathering of all the members of their house to celebrate their proud daughter. But their little happy time was interupted when half the house exploded with black flames going everywhere. What stepped out, didn't even look human. Naruto was seen, walking out the house with his Aura flowing off his body. His Aura was a black colour and screamed insanity and hatred. Minato was the first to charge at him. All he saw was a monster that had destroyed his house. Not the son that was neglected because of past sins. Naruto saw this from a mile away and struck Minato in the ribcage. He handled his speed which was considered unparallel to anything with such grace and cunning. He was nicknamed The Yellow Flash for a reason. And here he was shown true strength.

Minato was sent rocketing back into his wife and she found him passed out with 7 of his ribs broken, and funny enough, parts of his back. He'd never be able to go on any missions anymore. His back would not be able to take the stress. Looking in horror at the monster before her she too charged at him, her chains swirling around her as she tried a more distance attack. But Naruto sent off a wave of Aura at her which caused her to be paralysed in fear. Her body shook as she stood frozen where she stood. Slowly, Naruto approached her and proceeded to break her bones slowly. Starting with her fingers. Screams of sheer agony rung in the air as the people stood there shocked at what was before them. While the sound was haunting to them, it was soothing to Naruto. His insanity was because of them. His hatred was because of them.

And this power. Was because of them.

Thinking he was now bored with torturing her. (He had broken her two arms in several places and her leg was completely broken. Only fractured bones that would probably never heal resided in her leg). He walked away and took Osiris with him. The scythe just rested in a picture frame. In was considered useless to them as the weapon was just too heavy to pick up. So they hung it up. And even that was a mission. The scythe flashed a dangerous blue and was instantly weightless. Walking out the house he once called home, he set out to make his own mark. One which would be spoken of for generations and not anything like his parents which would be spoken of for a few weeks and then forgotten of.

The Legacy Of The Devil had begun.

Snapping his eyes awake, Naruto found himself at an inn he was renting. It had been 5 years since that happened and he would never have it any other way. He was now 16 but looked 20. His hair was slightly longer than what it was which now reached the middle of his back. He had grown quite popular since his little show 5 years ago. He began killing Grimm for a living with the occasional bodyguard duty, and was nicknamed: Necrosis.

He received this nickname due to his signature attack named, Necrosis. This was the first ability he learned when he went his own way. He was attacked by some Grimm who were attracted to his Grimm blood like moths to a bright light, and tried to kill him. But Naruto felt his Aura spike and he flourished the ability to be used as a frontal attack. Stretching his palm out he struck the one Grimm in the torso and watched as the thing turned into a pile of cellular mush in a matter of seconds. He maimed the other Grimm using Osiris.

Most feared him, and some respected him. One day, he found a doctor who could help him with his little mental problem. Despite having accepted his Grimm blood in him, he still had the insanity problem. He wasn't really the most stablising person to be around. The doctor gave him small white tablets that would help the incesid screams in his head stop. They worked. But not for very long. At least 10 hours he had of actually hearing his own thoughts. But even through all this pain and suffering, Naruto clung to the memories of Mito. The one who showed him happiness. He believed that there was a light at the end of the tunnel where he could be freed from the shackles of the screaming and insanity. But until then, he would swallow down the pills. With everything in his life, he did everything he could to hide the demonic arm of his. He hated the way the Grimm blood mutated like it did prior to him becoming what he is now, even though he accepted this new power. But he hid it with the usage of bandages and sometimes a sling. This was not a problem as he could effortlessly dispatch Grimm using only one hand to operate Osiris.

As he climbed out of bed he stretched his tired limbs and threw the curtains open. His body was lean and well crafted thanks to the many days and nights, training his body to be more effective in fights. After all, your body is your greatest weapon. Getting dressed which consisted of a grey tank top, blue jeans and black combat boots, he grabbed a red trench coat which had the Union Jack on the left sleeve he threw it on and made his way outside while grabbing Osiris and hefting it onto his back which stuck there apparently. Paying for his stay at the inn he made his way to get something to eat. Sitting down at a seafood joint he ordered a cup of coffee, no milk and very strong. He also ordered some sushi. The one food he seriously enjoyed. It was also the one meal he shared with Mito when she was still around. As he ate a man shrouded in a black cloak sat at the opposite end of the table.

"A new mission, Necrosis." he said handing him a black envelope with the symbol of a scythe on the seal.

Taking the envelope, he watched as the man got up and left. Sighing as he ripped out the letter he read what was written down. It was yet another hacky slashy mission. Sometimes he questioned if this was what he wanted. Sure the killing of Grimm was fun and all, but after your 1000th kill it gets boring. Naruto had slayed more Grimm than any person that ever lived. He even destroyed Minato's record for the most Grimm killed. Minato had killed a total of 250 Grimm when he was at the age of 20. Naruto killed 300 at the age of 13. He truly was a monster, worthy of the title of being a devil. Not a demon like his parents. A devil that is avoided at all costs.

But at least the pay was good. Some missions payed more than others which was okay, but Naruto had never seen a mission that was below 1000 Lien. Guess when there is a Grimm in your house eating the insides of your lover, you pay up. And Naruto always went where the money was good. Sometimes he'd help out with people who were not in that margin. His good nature sometimes over ruled his cold sadistic nature. After finishing his food and paying, he made his way to where the mission stated which was somewhere in some random forest. Finally making his way there he spotted four other people making their way to the the area he was about to go into. Deciding to see what they'd be doing, he sat down and watched. He didn't wait long as the area exploded with the Grimm charging after them. The Grimm in question was a Beowolf. This was getting interesting. But that was when his eye caught sight of a black bow on one of the heads of the 4.

He'd recognise that bow anywhere. There was no doubt. Getting up and grabbing Osiris from his back, he charged forth and rammed straight into the Grimm. The Beowolf was launched back quite a bit and while Naruto's Aura swirled around him. His eyes began to glow a violent purple as he stood there with Osiris resting on his shoulder. The 4 members stood there as they watched on at the man before them. But the one with the bow instantly knew who he was.

"You know. Attacking people is one thing. But harming these fine young women is another." said Naruto as he increased his Aura.

The Beowolf charged again only to have a scythe blade jammed into his side. The beast howled as it writhed about to try and get the blade out. But it didn't work. But that was when the scythe began to glow a powerful blue. Truth be told. The scythe fed off the energy of slain enemies. Or it could feed off enemies being killed. It was powerful piece of weaponry. Swinging the scythe, Naruto sent the Grimm into a set of trees and watched as the beast slowly got up. Smilling at this, he placed Osiris back onto his back and charged Aura into his hands. That was when the 4 girls heard the screams of the power being generated. And at that moment, they realised who was before them. They had only heard stories but never actually seen him before. A devil shrouded in darkness. A being said to have sold himself completely to the darkness and became the embodidement of pure insanity.

Sprinting at the Beowolf, he struck his hands on the skin and pumped his power into the beast. Seconds later the Grimm disolved into a pool of biological mush. With the task now completed. Naruto sighed as he turned to the 4 girls with his eyes returning back to normal. That was when the one with the black bow approached him. Once she was close to him she slapped him through the face. All the rest of the girls were shocked at what she did. But they were even more shocked at what came next.

"That's for leaving me you bastard." she hissed before bringing him into a kiss on the lips.

Naruto wrapped his arms around her waist as she pressed her body against his. Wrapping her arms around his neck and drawing him more closer. Breaking from the kiss she gazed into his eyes as he smiled to her, his vicious long canines slightly jutting out his mouth.

"And that is for staying in Vale." she added as Naruto chuckled.

"Why would I leave such a beautiful flower behind?" he cooed with her shrugging her shoulders while blushing a bit while he brushed some hair from her face.

"Blake you know this guy? I mean he's Necrosis. The legendary man who sold himself to the darkness." said the one with black hair with red in a few strands.

"You know him as that. But I know him as someone else." said the girl now known as Blake.

"Then who do you know him as?" asked the one with white hair.

"His real name is Naruto. And he and I were once boyfriend and girlfriend." said Blake with a smile as she leaned her head against his chest.

The 3 girls stood there as the two before them cuddled slightly more than normal. They looked to have known each other more than a regular couple has and they showed for affection than one. So they could only do what any other person would.

"WHHHHAAAAAAAATTTTTTTTT?" they shouted as they stared on.

And scene.

So the first chapter has been one which is pretty good and well crafted if I do say so myself.

Naruto will be the main protagonist in this fanfic and I will have him with the rest of the women in the harem stated in the author notes before the start of this chapter.

As well, I showed that Blake and Naruto had a history together and it will be pointed out as to their past prior to Blake joining team RWBY.

As well, Naruto's powers and abilities will be posted in the next chapter.

Chapter 2: The Devil Joins The Academy.

Coming soon.

Thank you for reading.

BlackSpirit101 out. ;)
