Chapter 1- Pilot

Hey Guys my hiatus is finally over but sadly I will be gone from the 2nd of December till the 20th so no updates during that period either. Anyway, here is a new pilot chapter for a story concept that I am working on. For those wondering about my other HSDXD crossovers, TKC will be scrapped and rewritten because I realized some parts don't make any sense. YFOG and IBDIBN will be continued but I need to rework and find my story diagrams for those stories. The RWBY crossovers are undergoing storyboarding work so give me some time. Also would like to get a beta reader for all my stories so PM me to get in touch if you are interested. This story was largely inspired by Fire & Ash. A really cool fanfiction that should really be read sad that it hasn't been updated for so long. So this is my spin on the Devil born Naruto with less angst and stuff.

25 Years Before Start Of Civil War.

A cry of a newly born child could be heard in the room as Venelana Gremory held onto a little blue bundle that contained her newborn son. He had a tuft of red hair on his head and blue green eyes as his father and elder brother, both of whom looked at him with love.

"He is a beautiful little boy. He will grow up to be strong." Lord Gremory said.

" Hopefully he can grow up in this relative peace that we have gained after the end of the Great war." Sirzechs said with a sigh as he regarded his little baby brother.

"Yes I hope so too son. So what shall we name him?" Lord Gremory said.

"Naruto. Naruto Gremory. I can just feel it. He will do great things." Venelana said as she rubbed her cheek affectionately with her newborn's.

Time skip 5 Years Before Civil War.

Naruto Gremory was in one of the open fields of the house training to master a new technique he had created. Beads of sweat poured down his shirtless torso as he kept going despite the exhaustion, having been at it for the past five hours.

"Naru-tan!" Sirzechs called out as he walked out of the castle to find his brother hard at work.

"Nii-san! What are you doing here?" Naruto asked as he sat on the ground, materializing a bottle of water before pouring it over his head.

"You should take a break. You are going to work yourself to an early death at this rate." Sirzechs said as he joined his brother on the ground.

"I know it's just that I want to show everyone that just because I didn't inherit the power of destruction that I am not weak." Naruto said.

Naruto was born with high magical power just like his brother. The odd thing though was that he did not inherit the power of destruction that his brother did. Rather, he had a unique set of eyes that he instinctively knew the name of. His unique eyes, crimson red like his hair and three tomoe in a circular pattern, called the Sharingan granted him predictive vision and the ability to copy anything he saw if his body was up to the task. Combined with the rigorous training he did, gave him the nickname the untouchable. He could also cast powerful illusions with his eyes that could distract opponents.

"You know that it isn't true anymore. You are plenty strong Naruto. In fact you are stronger than me when I was your age. But it doesn't matter what others think. The most important thing is that you should be happy with what you have achieved." Sirzechs said.

"Yeah. I guess you're right. But I still want to see if this technique works. So I'll go back to training then." Naruto said as he got up and went back to training.

"I won't distract you then. Dinner is in 2 hours. Make sure you shower before then. Mother won't be pleased if you are present in your current state. You remember what happened last time." Sirzechs chided.

"Yeah, yeah. I think my ear is still sore from that." Naruto said as Sirzechs gave him a wave before heading back into the castle.

3 Years Into Civil War.

"Damn it!" Naruto growled out continuously as his fist contacted the wall of Gremory castle, blood oozing from his knuckles as cracks appeared in the wall.

A now 28 year old Naruto Gremory, dressed in his special combat attire which consisted of a long sleeve black muscle shirt tucked into black combat slacks, combat boots with tape to secure the pants down. The sleeves were rolled so that they covered three quarters of his arm. He wore fingerless gloves with a metal plate on the back. Over that he wore a black flack vest that had multiple pouches. Strapped to his back was his trusty katana and around his waist was a large multipurpose pouch for supplies. He had matured well, his spiky hair striking an odd balance between looking messy and neat with two chin length bangs framing his face.

The Civil War had officially started 3 years ago. The descendents of the original satans and their followers wanted to resume the great war while another group of devils were against it since it would lead the devils to ruin. Naruto was an anti-satan faction fighter and had quickly gained fame in the group despite his young age. He was one of the aces of the group together with his brother Sirzechs and his brother's good friend, Ajuka.

He had mastered many different forms of magic with a particular specialty in fire and wind that rivaled the Phenex house, water that rivaled the Sitri and unparalleled mastery in lightning magic. His unique technique, the lightning armor, made him one of, if not the fastest devils. In addition to boosting his speed and reaction time, the lightning armor also boosted his strength and durability to scary levels, making him a feared combatant in the field.

"Naruto, there you are. You can't keep blaming yourself. You tried your best." Sirzechs said as he finally found his brother after the tragic battle that had just happened.

"It was my fault. If I had been faster, I could have saved him. I failed brother. We promised each other that we would make sure we had each other's backs so that we could come home safely. But I failed to keep my promise." Naruto said as he started crying, a burning sensation in his eyes.

"You can't keep blaming yourself for Takeo's death. He wouldn't want you to be like this. You did your best." Sirzechs said, trying to comfort his brother. One of the anti-satan faction camps had been attacked and many lives were lost, one of which was an extra devil named Takeo. Takeo was one of Naruto's best friends and was like a brother in all but blood, so the loss was painful.

"But if I was faster, he could have been saved. If I wasn't taking a break when the attack started, I could have been there to help them." Naruto said as blood started leaking from his eyes.

"And do what? Die valiantly with them? You may be strong but even you cannot take on an entire battalion by yourself brother. Now let me take a look at your eyes, they are bleeding." Sirzechs said, his initially angry tone softening when he saw his younger brother in pain.

"I'm fine." Naruto said as he opened his eyes, his normal three tomoe pattern shifting into something like an atom with three ellipses stacked together.

"Where are you going?" Sirzechs asked, concerned for his brother.

"To make myself able to kill a battalion so this does not happen again." Naruto said as he went off to train to prevent such a thing from happening again.

5 years into Civil War.

After that incident, Naruto had become much more powerful. The trauma from seeing his dead friend had somehow resulted in an evolution of his eyes into a stage called the Mangekyou Sharingan. He had the ability to use and control black flames that were hotter than any member of the house of Phenex and his flames burned continuously for seven days and seven nights, with no amount of water being able to put them out. He also gained the ability to manifest a giant ethereal warrior made of energy to fight. He had also delved into time space magic, trying to come up with a way to make a battle capable teleportation technique that would eclipse his current top speed using the lighting armor.

Sirzechs, Ajuka, Serafall and their team were stuck between a rock and a hard place. They had been tipped off on a possible supply route used by the Old Satan Faction and had hoped to end the war faster by cutting off the Old Satan faction's supplies. But it had been a trap and now two whole battalions of the old satan faction had them trapped with no possible point of escape. About half their team had already been killed off and the remainder were now hiding behind a cliff, waiting for the inevitable end.

"It seems like this would be the end. It's been good serving with all of you." Ajuka said.

"It would seem so old friend." Sirzechs replied.

"The feeling is mutual." Serafall stated.

"If we go down at least we go down with a bang." Sirzechs said before an object fell out of his pocket. It was a knife. Except this was no ordinary knife. First off it had three prongs and a thick wooden handle that had some sort of runic array. Sirzechs remembered that it was something Naruto had given him for use in emergencies.

"What is this brother?"Sirzechs asked as he took a strange looking knife from Naruto.

"That is a key piece for a new technique that I am working on. If I can get it to work as well as my theories, then I will finally be able to fulfill my promise of being capable of killing battalions." Naruto said with a hint of pride.

"How does it work?" Sirzechs asked.

"I haven't really worked it out yet but basically you just have to be thrown it down and I can be there in an instant." Naruto said.

'Might as well give it a shot.' Sirzechs thought as he threw the knife into the ground, surprising both Serafall and Ajuka.

"Sirzechs what was that?" Ajuka asked. His curiosity peaked by the runic array present on the knife.

"I don't know. Naruto said to throw it down in case of an emergency. He said that is was the key to his newest technique." Sirzechs said. Just as he finished that sentence there was a crimson flash and Naruto appeared next to them.

"What was that? And how did you get here so quickly?" Serafall asked as she landed unceremoniously on her butt after jumping in the air from shock.

"No time to explain. I need you all to follow my instructions carefully." Naruto said as he emptied the contents of his pack, revealing more of the odd three pronged knives.

"Alright then, I'll trust you to handle this." Sirzechs said.

"When I give the signal, I need you to throw these around the battlefield. Accuracy does not matter. What we need is coverage." Naruto said as he distributed the knives out.

"Alright we are set." Sirzechs said as everyone got ready to throw the knives.

"Here goes nothing." Naruto said as he charged power to his right eye, closing it. He faced the oncoming enemies and opened his eye, focusing on the centre of the enemy forces. From the focus point of his right eye, a column of black flames emerged, burning to death the enemies that were caught in the area.

"Now!" Naruto shouted as the old satan faction forces were forced to separate to avoid the black flames. A rain of metal fell on the battlefield with a few of the knives impaling enemies while most landed harmlessly in the ground.

"Hahaha! Was that your desperate last attempt? Now we get to kill all the aces of the anti satan faction. And with this a new war can begin!" The leader of the enemy forces proclaimed.

"Don't blink now." Naruto said simply as he held a sword in each hand, focusing lightning magic through the blades to make them sharper.

Then he was gone in a flash of red and what followed was possibly the greatest massacre anyone could see. There were flashes of red all around the enemy forces as Naruto picked them apart. He appeared wherever a kunai was and decimated any nearby force before appearing at another location in an instant.

"My word!" Ajuka managed to mutter while his two companions still had their jaws on the floor.

"So this is the power of time space magic..." Sirzechs muttered, having been made aware of what his younger brother had been up to recently.

"Your brother has been dabbling in time space magic? That certainly explains how he is doing this." Ajuka said.

"I don't understand. Isn't he just moving really fast?" Serafall asked.

"No. He is essentially teleporting from location to location. That is how he is able to change his orientation without any loss in momentum and how he can change directions without repercussion." Ajuka explained.

"Those knives act as markers I presume?" Sirzechs asked as he watched the last few enemies be killed off.

"I would think so. They give off a marking pulse that tells him where to emerge. The specifics of this technique are fascinating and to be able to create something so formidable so quickly... He is nothing short of a prodigy." Ajuka said as Naruto appeared next to them.

"Well that takes care of that problem. Come on. Let's go home." Naruto said as he cleaned the blood from his blade.

From that battle, Naruto earned the moniker of the red flash and also the name crimson reaper. With the deployment of the Flying Thunder God Technique as it came to be named, the anti-satan faction was making a strong push against the Old Satan Faction. They were able to quickly send aid as each person carried a marker on their person, allowing entire squads to be teleported behind enemy lines or the allow the transport of supplies. Within a year from that battle, the Civil war had come to an end and Sirzechs, Ajuka, Serafall, Falbium and Naruto were praised as the heroes of devil kind. It was also after the war that it was discovered that Naruto's eye powers had a steep cost.

A Year after the end of the Civil War.

"So what is the diagnostic doc?" Venelana asked as her son walked out of the room. He had been acting strange towards the end of the war and the Gremory had suspected that it had something to do with his eyes.

"Do you want the bad news or the worse news?" the doctor said.

"Just tell them. I can't hide it anymore it seems." Naruto said a little annoyed since he never enjoyed going to any treatment facility.

"Your son is going blind." the doctor said.

"What? Why? When?" the family asked in shock.

"Apparently the usage of my eye powers heavily during the war has damaged them and I will eventually go blind. My vision is already blurry as is and if I stop using my eyes it is estimated that my vision will deteriorate gradually till I go completely blind in 30 years." Naruto said.

"Is there anything that could be done?" Lord Gremory asked.

"Unfortunately no. His eyes are unique and we don't know what could happen if we tried anything but we will keep looking into this." the doctor assured.

After that, Naruto was constantly coddled by his parents and they forbade him from fighting in any of the side skirmishes that had been occurring with the other factions as well as the old satan faction that still refused to accept defeat. It was one night that Naruto had a vision. In his vision he saw a man with similar eyes to his own in battle with someone with what seemed like a multi headed and multi handed fox avatar. Beyond that he saw a wizened old man with purple eyes that had concentric circles in a ripple pattern. Following that vision, he would receive glimpses of events that he had no recollection of going through yet he experienced them in vivid detail as though he had gone through those events. After many nights of said vision, Naruto finally resolved to try and find the meaning behind his eyes and hopefully a cure to his blindness. He believed the answer lay with the old man who had purple eyes with concentric circles in them. So one night he just up and left his family, leaving a note telling him that he had left.

'Dear Mother, Father and Brother,

I am sorry to not be able to say goodbye in person but I know that if I had done that then you would never allow me to leave. I need to go and explore the world and find the truth behind my eyes. I also want to do some soul searching after all that I experienced during the war. So please understand and leave me be till I find my answer. I promise that I will return back to your side once more.

This isn't goodbye. It's until we meet again.

Naruto Gremory.'

"What do we do?" Venelana asked almost hysterically as her youngest son had mysteriously disappeared.

"We should send people to look after him and bring him back." Lord Gremory said.

"No father we should leave him alone." Sirzechs said.

"Are you serious? But what if something bad happens to him?" Lord Gremory said with worry evident in his voice.

"He will be fine. We just need to have faith in him like we always do. Naruto is not one to do things without reason. If he needs to be alone then we should leave him be. He will return." Sirzechs said resolutely as the family's thoughts drifted off to their youngest member.

So that's the pilot chapter for this crossover. Nothing much to say except reader response will decide what becomes of this. Naruto will be OP/Godlike in this story and he will be within the top 10 strongest beings in the universe for this crossover. Review to help me decide if I should make it a single pairing or multiple. Also help me decide if I should make his peerage his harem or keep them separate. Note that even if his peerage becomes his harem, only his special pieces i.e. knight and queen etc. will be paired with him. His pawns will be all guys and will be like independent cells that do things for him sort of like the Akatsuki with pairs that travel independently and rarely meet. Or I am thinking to make them something like the Spriggan 12 that is currently being done in fairy tail with them being like his shields.

Pairings for Naruto: Possible peerage piece indicated in brackets.

Yasaka (Queen)- Confirmed

Kuroka (Bishop)- Pending, likely

Akasha Bloodriver (Rook)- Pending

Tiamat (Rook)- Pending

Miya (Knight)- Pending

Lucy Aoi (Bishop)- Pending

Cassandra Aoi (Bishop)- Pending

Kazuha Aoi (Knight)- Pending

This list is open to suggestions. Also looking for suggestions on when Naruto should rejoin the main cast. The first option is he comes back during Rias' engagement to Riser. Second Option is he helps out as a masked character, i.e. Tobi, till the Leaders' summit where he properly reveals himself then returns back before the young devils gathering. Third Option is that he doesn't involve himself till Kokabiel comes out.
