This is my first attempt on a crossover story, this one will be involving Natsu from Fairy Tail, and the universe of Highschool DxD, now before the story starts, I would like to tell you guys a few things that will be happening in this story. First of all, this will not be a harem story, simply because there is WAY too many stories in the DxD and Fairy Tail universes that involves harems, on top of that, this story is not a happy and nice story, it will not be a angst or anything like that, but Natsu will not be his usual carefree self, at least not all the time, there is a few select people I will make him "the normal Natsu" for, but for devils in general, he will have VERY great dislike towards them, especially high society devils such as the pillar families. Reincarnated devils and devils who think like him in this regard will be far and few between, but he will most likely be friends with some of them, and in this story, the fallen angels will most likely have a little brighter side to them they are not stuck up angels nor as selfish as the devils, but somewhere in between. This also means bashing on the devils, Rias especially, as Sennybee98 wrote me, Rias, regardless of her families treatment of their servants, are a selfish little bitch, sure she treats them alright, but she is still all "me, me, me, I want this I want that," especially towards powerful servants. This is something that has me bugged from the very first time I saw the series, she turns people into devils, MAYBE against their will, in canon it works out only because of her huge jugs that Issei can't help but want to touch, but in many written stories, she turns people, who aren't even dying into devils. This bugs me greatly, and therefor in this story, she will turn Natsu into a devil, even though he isn't hurt, and this will not go well, for her nor any devil standing in his way. To explain this further, Natsu will be coming from the latest episode of the manga, that means he will be a lot more powerful. To give you a feel of it, Bluenote Stinger, a man who fought with Gildarts ALMOST on par, is an immensely powerful wizard/mage. In the newest manga, Natsu takes him out with ONE casual attack, this should give a feel of the level of power I'm referring to. To put up some classes, Ultimate Class Devil will compare to that of a very strong S-class wizard, borderline SS-class, maybe, Super Class Devil, such as Sirzechs, is the same level as Gildarts, an wizard allowed to go on SSS-class missions. Now I really like Natsu, and because the mange hasn't explained his current level, I will allow myself to say that Natsu, will be more powerful than a Super Class Devil, mainly because of his lightning flame mode, which we will see fairly early in this story, but also remember, that when he goes into Dragon Force, his power is increased so much that even before the 1 year training gap, he could compete with very strong opponents. So Dragon Force at his current level will be that much stronger. Also because I really dislike canon Issei, he will be the dragon punching bag for Issei. That is my idea so far at least.

Enough introduction!

Hope you like the story!

Chapter 1 - Epilogue

Load explosions could be heard from a remote forest in the out skirts of Magnolia, and clouds rose from the area. The clash between two of the strongest mages in all of Fiore was taking place, and for one of them it was a fight for all he cared about, and for the other, it was to end his own life, but as might as he might be, he could not take his own life, and needed one man to do it for him. The two mages was Natsu Dragneel, wizard of Fairy Tail, the other was the black wizard Zeref, and he was in many people's eyes the most evil wizard to ever exist. His creations, demons, had roamed the world, with the purpose of killing him, but they were never strong enough. By now all of those demons had been defeated by Natsu and his friends from Fairy Tail and the last remaining threat in Fiore was Zeref and he finally got what he wanted. A fight with Natsu, at his strongest, or so he thought. The battle between Zeref and Natsu had lasted for days and even though Zerefs magic was killing everything in sight, Natsu could negate them with his own now very powerful dragon slayer magics, the dual elements in Natsu gave him the power to negate and fight Zeref on somewhat equal terms, that and of cause this also included his use of Dragon Force. But it wasn't enough, as powerful as Natsu had become and as much as he could actually now fight Zeref, he lacked the power to kill him and Zeref knew this. Even though their fight was one of legend, it had a predetermined outcome, so Zeref decided to give Natsu one last chance to gain that power, but instead of just letting Natsu go, he also decided to give him a punishment for not being able to, with the many years of training to defeat him.

"Natsu.." Zeref spoke, "as we both can see, you still cannot defeat me, but I have decided to grant you once last chance to gain power.." his word, to Natsu, was confusing. Natsu had given it his all, he fought with Zeref on even ground but could still feel a rather large difference between them, but why didn't Zeref just kill him then? "But because of your lack in strength, even after I gave you more than 3 years after Acnologia attacked Tenrou, I have decided to also punish you!" Zeref spoke in a very dark tone, this sent a chill down Natsu's spine. "Since this world is not adequate enough for you to gain strength, I will send you away from all your friends, all you know will be different! You will live with the fear that if you cannot get stronger, I will kill all your friends." Natsu's face twisted in horror "YOU WILL NOT TOUCH THEM!" He shouted, making an offensive stance ready to attack Zeref again. Zeref looked at Natsu with a last shred of hope that Natsu would grow stronger and be able to defeat him.

Zeref started to glow with a mist around him in the purest black color, he radiated a power Natsu had never felt before, even in Dragon Force Natsu couldn't comprehend just how far behind Zeref he actually was. This made him shiver, both of excitement as his usual self wanted to fight a strong opponent, but also with fear, a fear he hadn't felt since Tenrou first with Gildarts, and later with Acnologia. This made him take a step back.

"Grow stronger Natsu, you are almost at a level that can kill me, that day will come soon! Just remember, if you do not grow stronger while in the world I send you to, I will kill all of your friends at Fairy Tail, and fret not, I will inform them as to where you are and the conditions to our little agreement here today." Zeref spoke in a rather relaxed tone, one he seemed to always use when speaking to Natsu, and just before Natsu could respond or say anything, Zeref spoke again. "I will monitor you in this other world, and I will see your progress, when the time comes, I will appear to you in that world and bring you back for a fight that will then have all of your friends lives at stake, remember that, Natsu.." Natsu had no time to respond as he was enveloped in the magic released by Zeref, it felt horrible, as if his very being was being torn apart.

The sphere around Natsu grew bigger and bigger, "AaARRRARARRHHG!" Natsu let out a groan of pain, but then it happened, everything disappeared before his very eyes, and in a bright flash everything was gone and he fell unconscious.

"Now Natsu, if you fail this task, your friends will die the most excruciating way I can muster, and you will be forced to watch before I kill you as well.." Zeref spoke this in a soft voice even thought Natsu was already long gone.

~Gremory Mansion~

Serzechs was sitting in his office dealing with his never ending pile of paperwork, he had been wondering all day if something would ever happen that could relieve his boredom, if only for a few hours. He had been stuck in his office all day, while Rias had been home for a visit, and she had been a little lost if that could describe it. She had married Riser Phoenix a few weeks back and was now forced to live with him while her servants now also served him, not to the same extent that his own did, but he could still somewhat command them around. Rias newest pawn Issei had failed to save her even though Serzechs himself had provided enough possibilities for him to do so, but then again, Issei being a pawn worth 1 mutated pawn piece wasn't the strongest and therefore not the best option. Even though he had the boosted gear, he was the weakest host of Draig that has ever sat food on this earth.

While Sirzechs was sitting in his own thoughs, Rias was sitting in her room sulking, but that did not last long, as both her and her brother Serzechs was interrupted from their train of thought by a massive explosion in the forest near the mansion. The surge of power that followed was enough, even at a distance, to make Sirzechs himself sweat, and he noticed this with wide eyes. He without another thought teleported outside to the from gate of the mansion, and he was quickly followed by Rias, his wife Greyfia and his parents Lord and Lady Gremory.

"Did you guys feel that massive power as well?" They all nodded to Sirzechs question, "it feels at least on par with Greyfia if not myself, but it radiates authority like a dragons would!" they all looked at him with wide eyes as he just stated something that would almost seem impossible, but none the less started walking towards the massive crater the explosion had left behind.

~break~

They reached the crater rather fast, and what they found baffled them. Inside the crater was a boy, he looked a few years older than Rias, maybe around 20 or so, and he radiated power. He didn't look like he was injured at all, but he was unconscious. What threw them all off was his appearance, pink hair, a scaly scarf, an open vest with 1 sleeve and while baggy pants, he didn't look like anyone they knew.

"How does this boy radiate this much power?" Rias asked, clearly shocked that a boy not much older than her was giving of an energy signature about the same level as her brother. What seemed even more impossible was that he appeared human! "I don't know Rias, it's hard to believe a human can emit this much power, and not be a being other than human.." Serzechs said with a look on his face that told of great interest in this boy. Rias being who she was, a devil, started having thoughts towards herself and her peerage, this piece could be what she was looking for, what she didn't seem to get from Issei, though Issei with enough training could prove very strong, he was at no level currently to battle anyone stronger than a low class stray devil. "I'm gonna make him mine!" Rias declared, a look of surprise hit her parents and Sirzechs just looked like he was expecting this from his sister.

As Rias walked forward, she summoned the 7 remaining pawn pieces she had left and tightened her grip around them, she was hoping for a slight miracle. 7 pieces of regular evil pieces would probably not be enough, so maybe, just maybe they would mutate. She held them toward the boys chest, and started chanting. "In the name of Rias Gremory, I take you into my care as my servant, be reborn and live your life for me!" As she finished chanting, the miracle happened. ALL 7 pieces mutated, and what looked like scales started to appear on them before they floated into the body of the boy, as to which his unconscious form grunted in slight pain.

Little did Rias know, that what she just did, might turn out to be the worst decision she has ever made in her life…

I know this is a short chapter, it's the prolog for this story, and I hope you like it, while I'm at it, I would like you all to write who you would like to be paired up with Natsu, only thing is, it CANNOT be a devil living under the rules of the underworld, that being said, a devil who is reincarnated will be possible, but I will most likely not pair him with a devil, I'm thinking either a fallen angel or maybe a dragon, my first thought would be Taimat, but let me know what you think and what, I'll try and take into account what you guys want as well. I look forward to writing this story, because Natsu will be, for all intended purposes a STRAY devil, I might change the title later on, because I plan on giving him a Draconian body when he meets Great Red or Ophis, because he doesn't want to be a devil. But I will need your opinion on this as well, so let me know what you think! Hope you like it!

Please review and tell me likes and dislikes.
