This is another Fairytail DxD story that I had wanted to do for a while, it's probably been done for a while now seeing as I wrote it shortly before my Christmas break. I didn't put it up because I wanted to iron out a few small details in this story and my other stories and wanted to get the more popular one updated, aim for roughly 8k this chapter if I continue the story the other chapters will be shorter like 5-6k each give or take a few hundred words, Anyway I hope you enjoy this story.

A warzone no hell would better describe what Magnolia looked like now, between the mixture of rubble between the Tartaros guild hall and the buildings of Magnolia and not to mention the two enormous ferocious dragons fighting in the sky above who were causing massive shockwaves from the collisions of their bodies which would disperse nearby cloud cover.

The two dragons in question were none other than Acnologia the self-proclaimed dragon king and Igneel the Fire Dragon King. The Black dragons sudden appearance had caused Igneel to reveal himself to Natsu and that he had been hiding inside him this whole time watching over him, this of course didn't sit well with the slayer who was outraged that all those years he spent searching for his father were indeed in vain when he was with him the entire time.

However the pressing matter of Tartaros took priority on finding out why his father did what he did, but to encourage his son further Igneel turned the request of stealing the book of E.N.D into an official guild request with the reward being anything he wanted to know. Of course this got the dragonslayer fired up and he immediately began his battle/struggle with Mard Geer the current strongest of Zeref's awakened demons.

However even with the addition of Sabretooth's twin dragons Natsu was barely able to damage Mard Geer who continued to mock and snigger at their futile attempts to stop his plan to bring back E.N.D the ultimate demon. It was only with addition and surprise revelation of Gray becoming a Devil Slayer that the tides turned slightly in the favour of the four slayers. That is until Jiemma the ex-Sabretooth guild master who now turned demon intervened and separated Gray and Natsu from Sting and Rogue to get his revenge on the twin dragons.

Even though Natsu and Gray now had to face off against Mard Geer in his etherious form on their own they didn't falter, they pushed on and fought harder with everything they had and that's where we are now Natsu and Gray had delivered a mesh of devastating attacks with their unmatched team work but the etherious demon who now stood at least 8ft tall looked completely unscathed.

"You've shown me a good time human wizards but now it's time to finish you and I shall do so using a power that exceeds that of magic…a spell no curse that I devised to kill Zeref!" Mard Geer said in a dangerous tone as he pulled one wing over the front of himself almost in a protective manner. "To kill Zeref but why?" Gray asked in a shocked voice unable to comprehend the words of the demon in front of him.

"In ages past all magic belonged to the one source, what you know as the one magic. It later become the many different types of magic there are today, however a long time ago Master E.N.D was able to create a power that exceeded that of magic, curse power. As to your other question even I am unaware of the reason why, just that I must and since my awakening it was my soul purpose to do so and bring back master E.N.D!" Mard shouted before placing his hands on top of each other, the top one had the middle and index fingers pointing upwards with the rest closed and the bottom hand had all the fingers except the middle and ring finger extended.

Suddenly a blackish purple miasma appeared around Natsu and Gray and began encircling them, "Crap I don't like the look of this shit, Natsu don't let it touch you" Gray called out to his comrade who nodded in response. "Very perceptive human but this is only the beginning of my ultimate curse, Memento Mori, The Memory of Death! Be honoured that you should perished by its doing, a curse so powerful that it was designed specifically for killing Zeref, so powerful that it destroys the very notion of life and death!" Mard shouted out in madness revealing the details behind his curses power seeing as there was no possible way they could escape.

Gray and Natsu could only stare at each other in shock unsure what to do in this situation, they spat useless ideas at each other until Natsu came to one conclusion even though it went against everything in his being but he knew it was the only way to save Fairytail. "Gray you're a Devil Slayer, is there any possible way you can get through this on your own?" Natsu asked as his eyes become shadowed by his hair, "Huh what are you talking about, oi Natsu you better not be thinking what I think you are!" Gray shouted as he gripped his best friend's tattered jacket.

"Kinda of ironic ain't it coming from you eh?" Natsu said in an amused tone which angered Gray to no end realising what he was getting at, "Even if I could get out Natsu I wouldn't be able to fight him alone!" Gray shouted as his Grip lessened on Natsu, "What would I tell the others if I just let this happen huh? What would Erza, Gramps, Happy, Lucy, Laxus, Lisanna, Mira Gildarts, Wendy, Gajeel, hell what the fuck would your dragon do eh? What the fuck then Natsu think about I, no matter how we look at it you're the heart and soul of our guild what do you think would happen to Fairytail without you?!" Gray shouted in pure anger ready to sock the slayer upon his ready but found himself unable to and starting to tear up slightly.

"I don't know, but what I do know is that if we don't do something about this guy and Face if both aren't stopped then the world of magic is very well and truly over so I'll ask you again can you make it through?" Natsu asked in a determined voice as he looked at Gray with his now molten draconian eyes, "Y-yes but if I do there's no guarantee that I'll be able to fight afterward" Gray replied in in an unsure disheartened tone but looked up once he felt a reassuring hand placed upon his shoulder, "Don't worry, just give a really long chain attached to a really sharp spike."

Meanwhile outside the miasma Mard Geer could feel the power of Memento Mori entering its final stages, he began laughing knowing that it wouldn't be long until those two insects became nothingness, erased from existence. His focus on casting the curse was disrupted when he felt the familiar sting of Devil Slayer magic but this time at a much higher degree especially in his right shoulder. This momentary lapse in concentration gave Gray the opportunity to burst out through the miasma only to collapse onto the ground a panting demonic mess as half his body had become demonised to deal with the effects of Memento Mori.

"So Silver's power allowed you to escape, can't say the same about your comrade though," Mard said in an arrogant voice as he began walking over to Gray while trying to dislodge the ice spike from his shoulder but to no success, "YEAH WELL I CN'T SAY THE SAME ABOUT YOU EITHER!" Natsu roared out from within the now unstable Memento Mori, Marg Geer was immediately caught off guard by the loud yelling but even more so when he felt his body being dragged into his own curse, "In a way this is Natsu own curse, to die for the people he loves so they can live, the memory to live" Gray spoke out weakly before giving into his injuries and falling unconscious.

"No what are you doing you idiot, let go!" Mard Geer roared in protest as he tried to use his wings to fly away but to no avail because as soon as he was air born a quick but harsh tug on his right shoulder brought him to the ground "Not on your life!" Natsu shouted in return before swiftly dragging the struggling grounded demon ever closer to him.

"I won't stop, I will beat you so Igneel can take that book!" Natsu grunted in determination as he rooted himself in a firm stance before pulling Mard Geer inside vortex created by Memento Mori, "ENOUGH!" Mard Geer roared out in anger before collecting a greyish white energy around his clawed his hand and swiping it through the end of the ice spike protruding from the back of the demons shoulder. This then allowed the demon to pull the rest of the spike out before releasing a deadly roar of pain.

"Where are you?" Mard hissed in anger as he looked around for the pink haired son of the dragon, "Right here!" "Fire Dragon's Iron Fist!" Natsu called out as he appeared below the towering demon before delivering a staggering flaming uppercut to Mard Geer's jaw causing him to stagger back a few steps. "WWWRRRAAAGGGHHH! Filthy human how dare you!" Mard shouted but soon realised Memento Mori was entering its critical stage and that he needed to get the fuck out of there.

But before the leader of the demon guild could take off "Where do you think you're going?" Natsu said appearing with lightning sparks flickering around his hair causing Mard Geer's eyes to widen at the fact that he didn't know that the slayers lightning dual element mode increased his speed and now his was going to pay for it as Natsu had him in an unbreakable joint lock, "Bastard let me go!" Mard demanded creaking his head back slightly to glare at the Dragonslayer, "no can do if I'm going down you're coming down with me" Natsu said in a determined voice before the area around them started glowing gold.

"No, no, no, this can't be happening. I was supposed to eradicate magic, kill lord Zeref and rule with Master E.N.D how could a lowly human wizard like you get in my way?" Mard questioned in fury as the light started intensifying, "Simple you underestimated us Dragonslayers…" Natsu started before he was nearly completely consumed by light

"And you underestimated Fairytail"

Unknown location

Natsu eyes fluttered open, at first weird vivid colours filtered into his vision and he recognised nothing, then gathering his thoughts together and allowing his raging headache to settle he realised that o second glance he still didn't recognise anything but if he could compare it to anything it was strangle akin to the celestial spirit world although this place looked a hell of a lot more trippy and lonely judging by all the rubble laying around him.

"HUMAN!" Natsu was snapped back to reality by a devastating drop kick to the chest that Natsu was almost certain cracked his chest. At any rate the kick was powerful at sent him a good distance away crashing through some of the rubble. "You'll regret messing with me human" Mard said in a powerful deadly tone as his aura began to flux more than anytime it had before causing Natsu's eyes to narrow in hatred towards the demon as his own magic flared in response

However before either Mard or Natsu could make a move to strike a great shadow fell over the two, followed by a deafening roar that dwarfed Acnologia's or Igneel's and when followed back to the source belonged to an enormous western style dragon who made the aforementioned dragons look like infants. Natsu and Mard could only gawk at the beast even as it moved its enormous claw to a striking position. Before either Natsu or the demon could react the scars formed behind them sucking them in, it was as if the dragon had torn the fabric of space apart and forced them through it.

Meanwhile at the Gremory Battle grounds (A/N: the place Issei fought Riser by himself)

Two people stood apart from each other, one was a young teenage boy of average looks with brown hair and eyes and his current biggest standout feature a red scale like gauntlet that had two yellow triangles pointing backwards and a green jewel in the centre. The other was an older man who looked in his mid-thirties with slicked back dirty blonde hair, blue eye, had a long brown trench coat on and underneath wore a simple shirt blue jeans and some suit shoes (A/N: as you can tell been a while since I've watched the first season)

The two were standing in what appeared to be an empty colosseum, well to normal person but these two guys were normal people no not by far. These two people are devils a race that recently has been finding its numbers of pure blood decreasing so as to prevent total extinction they invented evil pieces where they could use chess pieces to reincarnate those whom they chose as a devil, the usual candidate's humans. The colosseum they now stand in was designed for what devils call rating games and is a separate dimension as to avoid any damage to the real world.

"Attention Issei Hyoudo, Riser Phoenix are both of you are of the stakes of the upon the outcome of this match?" a stoic feminine voice asked which unmistakably belonged to the wife of the Sirszech Gremory the Crimson Satan, Grayfia Lucifage. Both contestants nodded, "Very well, on my count then" Grayfia said in her usual stoic voice before both Riser and Issei dropped down into battle stances.

"3"

"2"

"1"

"ALERT! ALERT! MASSIVE POWER FLUCTUACTIONS!"

Before anyone who was watching knew what was happening, hell before Issei and Riser knew what was happening they were teleported out of the arena and Grayfia was already at work trying to decipher what the hell was causing a power surge that was greater than that of any of the Dragon Kings or Satan's.

"Grayfia what is it can you pull it up on screen?" Sirszech asked as he entered a neon blue room that had Grayfia and several other devils in it monitoring just as many screens. "Yes Lord Sirszech the origin is coming from arena it appears to be settling down although I'm picking up two very large power levels although I can't determine what they are yet" Grayfia said causing the crimson haired devil to smirk, "It's okay just bring it up and well see what happened….ugh a dimension rift!" he started but almost choked on his words when he caught the tail signs of the rift closing.

In the Coliseum

Natsu and Mard Geer now in human form staggered to their feet but the demon was first to recover due to his sheer impending rage, he immediately shifted into his etherious form shocking those watching the two through the screens, "Dragons, Dragons, all these Damn fucking dragons getting in my way, First Acnologia then Igneel and then that giant red fucker I've had enough of Dragons and you damn humans!" Mard Geer roared before slugging Natsu with grey curse infused punches so powerful the shockwaves caused craters to form beneath the two, but upon the final word he slugged Natsu in the gut causing him to cough up a considerable amount of blood before he was sent flying into a pillar which collapsed on top on him.

Sirszech and Grayfia could only look on in shock at what the demon had done to this simple human and how it had ended his life without any sign of mercy, Sirszech was strongly considering going to face the demon himself but he knew a fight between himself and a demon this powerful would some negative repercussions like destroying the dimension and the fight escalating into the real world.

However a strong power source was detected from where the pink haired boy had landed causing the two devils to look in the direction the rubble that now had lightning arcing around it and was slightly steaming "UUUUUUUURRRRRRGGGGGGGHHHHHHH!" Natsu roared out before the slagged rubble was blown in all directions revelling him to be wearing only his combat boots and tattered jeans and scarf of course with his ripped upper body for all to see.

"Good you can still fight, show me what you are truly capable of human" Mard said before taking off towards Natsu who turning into a lightning bolt to cut of the demon "Lightning Flame Dragon's…" "What makes you think it will work?" Mard Geer mocked thinking the slayer was going to use a hammer attack like last time and seeing as it had no effect in his regular form what did he think would happen now "RRROOOOAARRR!" Natsu shouted out surprising the demon as he was not prepared to block an up close roar. This proved beneficial to Natsu as Mard was sent skyward by the large torrent of lightning and flames and Natsu pushed deeper into the ground from the force of the attack.

To say the watchers were amazed at Natsu's display of power was an understatement, they had never seen magic like this before, there was no knowledge of magi that allowed someone to shoot fire or lightning from their mouths or other parts of their bodies. "Lord Sirszech the dimension took heavy damage from that attack look!" a random devil said in a panicked voice as she pointed to where the demon seemed to be lodged in thin air with cracks surrounding him, "Get a group of high class devils we need to stop these two before things get out of hand" Sirszech said in a calm manner receiving a nod in response from Grayfia. However before they could move they noticed a frighteningly massive power increase.

Moments earlier with Mard and Natsu

"Yes it wouldn't be interesting if it was a one sided battle, but your attack did nothing more than add to my fury. As soon as I kill you I'll find my way back to Fiore a slaughter every member of your guild, perhaps I'll start with that exceed you cherish so much" Mard said in a deranged voice as he descended down to a height to where he was just barely hovering above the ground. This made Natsu's blood boil to the point where t felt like magma was flowing through his veins and he started trembling with his eyes shadowed by his hair.

"Now die human!" Mard Geer roared out as he charged towards the dragonslayer collecting curse power around his right fist and then it happened, "Like hell I will" Natsu shouted in defiance before planting a flame clad fist in the demons face sending him flying back a few hundred feet through a few structures stunning the onlookers with his sudden burst in power that could now match any of the Satan's and possible more.

"This power where did it come from?" Mard asked himself but almost instantaneously Natsu closed the distance between himself and the demon before delivering a devastating knee strike to Mard Geer's jaw causing him to recoil his head back in pain. Suddenly Natsu was cloaked in immensely hot golden flames that engulfed his entire body causing Mard Geer as well as the on looking devil's eyes to widen. "Dragon Force!?" Mard Geer shouted out almost in a fearful tone while Sirszech and the other devils where still shocked at Natsu's sudden change in appearance.

"His body is covered in dragon scales!" Sirszech stated in surprise which caused him to smirk and the other to become equally surprised, "Is he really human?" Grayfia asked in a suspicious tone as she looked at the scales that now covered all of Natsu's back, a good portion of his face, forearms and ribs as well as the backs of his calves. "I don't know, but to my knowledge a normal human can't be this powerful even if they possess magic, that last attack heavily damaged the dimensional barrier I'm not sure if it can last much longer" Sirszech replied in her usual stoic tone.

"Dragon Force!?"

"Yeah, inherited directly from Igneel, now bring it!" the Dragonslayer shouted before he charged the demon and struck him with a devastating iron fist attack that caused an enormous shockwave followed by the arena floor being completely lifted up. Mard Geer knew he now had to take the human seriously, that attack alone did some serious damage and it was one of the weaker ones so who knows what some of the more powerful spells could do. Mard Geer responded to the punch by throwing his own curse infused one which connected with the dragonslayers jaw causing him to stagger back and grunt in pain, but with his new found strength and much to the demon's surprise he was able to take the punch like a champ.

"Yddrasil!" The demon called out after jumping up into the air and summoning two white portals that released two insanely huge plant like columns which combined into one before it plummeted downward towards the awaiting dragonslayer. "Does he intend to take that attack?" Sirszech asked in surprise seeing that Natsu only had crossed his arms in what looked like a protective manner. But what Natsu did next surprised them further when he lit himself on fire and began building up power causing the golden flames to increase.

"Fire Dragon's Sword Horn!" the slayer shouted before flames erupted from his feet causing him to rocket towards the impeding attack, Golden fire swirled around him specifically around his head before it collided against Mard Geer's Yddrasil causing an extremely large explosion to occur the light from which blinded bot demon and mage, the explosion however just about did it for the dimensional barrier as it began falling apart.

"Lord Sirszech the dimension is falling apart their gonna wind up somewhere in the underworld!" a random devil said causing Sirszech to grunt in annoyance, but then again it had been a long time since he had got to fight any one maybe this could be fun if he gets to fight but either way if he fights or not it's win, win for him, well the devil race, "Grayfia we're moving out at once, the demon needs to be taken care of, however the human interests me" Sirszech said in an excited tone before both he and the maid teleported out of the room in a red flash.

With Natsu

Once again the slayers eyes fluttered open and this time he could see a red sky surrounding him, yet again more unfamiliar surroundings but that was the least of his worries as he realised that he was falling in mid-air and that he saw Mard Geer Flying towards him "Enough of your tricks human!" the enraged demon shouted as he grabbed the slayer's face and picked up his speed intending to drive Natsu's body into the ground leaving nothing behind.

"…Uggghhh…" the demon was forced to spit up some blood when he felt a devastating strike make contact with his stomach, this resulted in him letting go of the pinkette's face, "Alright then no more tricks" Natsu grunted out as he ignited his right foot in brilliant golden flames all the while not noticing the two presences the two presences in the vicinity "Fire Dragon's Talon!" the slayer roared out before striking the demon leaving three horizontal scars across Mard Geer's chest causing him to cry out in pain.

The force of the attack launched Natsu down towards the ground but not before "And ROOOAARRR!" upon shouting this an immense golden stream of flames erupted from the slayers mouth, luckily for the demon he saw this but not soon enough o could only cross his wings over himself to shield himself from the blow.

"The boy his power seems to be getting stronger and stronger, intriguing" Sirszech said with a smirk which Grayfia knew all too well, "Yes but the fact that the demon survived both those attacks with so little e=injuries is rather concerning" Grayfia said looking towards Mard Geer who had now recovered from Natsu's roar and was charging towards the slayer as if he hadn't been harmed.

"Let's finish this human!" the deranged demon called out as he accelerated towards Natsu who was getting into a stance to counter the incoming attack, "Yes let's" the pinkette replied before delivering a devastating flaming uppercut to the demon's jaw sending him skyward, "I'll end this right now" Natsu said with venom and determination laced in his voice as he crossed his arms in an X pattern before he was engulfed in flames which was followed up with a dramatic increase in magic power.

"Dragon Slayer Secret Art Hidden Fire Form: Crimson Lotus Phoenix Blade

Faster than Sirszech or Grayfia could follow Natsu took off and closed the gap between him and Mard Geer before head butting the demon in his mid-section causing Mard to spit up a lot more blood this time from the sheer force of the impact. But the spell still wasn't over yet "UUUUURRHHHGGGGHHHH!" the dragonslayer gave out a large battle cry before both himself and Mard Geer were engulfed in even more flames which caused spiralling explosions further damaging the demon who could only roar out in pain as the speed at which he was being rammed at increased further increasing his pain. The pain didn't stop until they were a few thousand feet up and Natsu couldn't push his body any further so he flung Mard Geer to the side.

But not before using one final spell to finish the job "Fire Dragon's Piercing Talon!" originally a spell designed to break dragon scales Natsu believed it would be more than enough to break through Mard Geer's demonic scales and pierce his heart. Natsu's golden flame clad hand easily pierced through the demons chest and struck his heart killing him instantly but now Natsu had a different problem, he was falling at an increasing rate and his magic was practically at zero from what he could see with the scales on his arms slowly dissolving back into his skin.

"No can't lose…consciousness…need to stay awake" however the slayer was simply to injured, he had lost a significant amount of blood in his fight with Mard Geer not to mention the broken bones but healing abilities could take care of them.

Lucky for Natsu two guardian angels well devils were watching the fight and one crimson haired individual was very impressed to say the least so they were kind enough to catch the falling teen. "What is it you intend to do with him lord Sirszech?" Grayfia asked as she lay Natsu upon what appeared to be a large red magic circle. "You saw it yourself Fia, he's immensely powerful, that's the power to be a high class devil meaning he could start his own peerage, this will greatly help in replenishing or race's numbers." Sirszech said as if it was the best idea to ever be conceived.

Grayfia did agree that the boy was definitely powerful enough to become a high class devil with his own peerage. "However this isn't exactly the place nor the time to do such a thing let's take him back to the castle, you can make a proper analysis with MacGregor there" the crimson haired Satan said receiving a nod from Grayfia before the three were engulfed in a red glow. When it faded Natsu, Sirszech and Grayfia had all disappeared leaving behind a significantly destroyed area from Natsu's attacks.

Several days later

Several days had passed since Natsu had fought against Mard Geer and he had yet to awaken, but in these few days he was indeed identified as very human although they couldn't figure out where his unfathomable levels of magic power came from for someone so young. Even MacGregor was stumped, he was revived as Sirszech's bishop using but required to bishop pieces to do so, it is said he is a master magician and is capable of using all types of magic. But the magic this boy possessed was beyond foreign to him, this however only made Sirszech want to turn him into a devil sooner.

The whole ordeal between Issei and Riser which revolved around Rias' arranged marriage to Riser, hence why Issei challenged the older devil to the rights of Rias' freedom to choose whom she wanted to marry. The battle had been put on hold since the dimension had been destroyed and they needed to create a new one, plus Sirszech didn't want to reveal Natsu to anyone, the only ones who knew about Natsu beside Grayfia and Sirszech, were MacGregor and Sirszech's parents.

Right now though Sirszech and Grayfia stand over an unconscious dragonslayer, "Are you sure about this Lord Sirszech?" Grayfia asked as she handed an evil pawn piece to the crimson Satan who just nodded in return, "Yes now is the right time to do so," he replied and then without saying anything further he placed the pawn piece over Natsu chest before allowing in to float in place. Both Devils watched as the piece morphed into what they knew as a mutation piece meaning he definitely was as powerful as they thought. They both leaned forward in anticipation as the piece slowly started to descend.

However both were puzzled when the piece remained stagnate after moving barely an inch, it was then almost immediately Natsu's body was covered in red markings and he was crying out in pain, which was soon followed by a shock wave that sent both devils reeling back "Lord Sirszech what's happening?" Grayfia asked having never seen something like this before. "I don't know but…what?" the crimson haired devil started but frozen in his place when he saw Natsu standing in front of now with purplish black markings on his body, his eyes a blood crimson colour rimmed in black and his hands clad in orange and red flames.

It wasn't his eyes or the markings that surprised the Satan, it was the position his hands were in it looked like he was trying crush the piece, "Is he trying to…" "Huurrgghhh!" Natsu clapped both his hands together on the evil piece shatter before his instincts told him to get away. Instinctually Natsu blasted a hole in the wall, his body still felt heavy like it usually did after a major battle but his advanced healing dealt with the more minor things however the broken bones would be a different story as soon as he got away he needed to focus on them.

As much as he knew it was gonna hurt like a bitch to do this, he didn't have much choice "Lightning Flame Dragon Mode!" the slayer called out before he was cloaked in lightning and flames. Natsu then jumped out through the hole in the wall and skydived to the ground bellow he needed to as close to the ground as before he pulled this stunt off.

"Lord Sirszech what do we do, what happened?" Grayfia asked as she walked over to the hole in the wall completely stupefied for once in her life, "I don't know, the piece never entered his body so I don't know if he can be considered a stray but It wouldn't be wise to allow a being let alone a human with that much power roam the underworld himself there's no telling what havoc he could cause and if it connects back to me the other three will have my head."

"He's injured so he'll be less of a handling, you and a group of devils take care of this, capture him and bring him back alive so we can straighten things out or at least figure them out, use force if necessary" Sirszech said before Grayfia nodded a jumped out after Natsu expanding a pair of black bat like wings. She was closing in on him incredibly fast and was starting to think she wouldn't need the other devils, well that was until Natsu turned into what appeared to be a golden streak of lightning after chanting the words "Arc of Lightning"

This threw Grayfia way off, they were already extremely close to the ground and it didn't help that passing through the static residue slightly paralysed her causing her to crash into the ground. Natsu used the dust that was kicked up by crash to swiftly make his way over to an over look above a large flowing river. "Well, all or nothing" the slayer said before he dove down into to the fast flowing river which turns out might not have been the best idea ever.

Even if the river provided Natsu with a method of escape the ever present large boulders provided an excellent method for inflicting further pain onto oneself. Natsu allowed the River to carry him for some time and it was only when he decided that he was at a decent distance from the castle that he got out of the river. When got out of the river he felt exhausted, he could see his skin was back to normal apart from being a bit paler from the cold temperatures of the water, even if he was a fire dragonslayer he could only keep himself warm for so long.

When he looked up Natsu could see he was at the foot of a mountain, one that reminded him of one him and Igneel went to for training, "Maybe I can hide out up there for a while" Natsu said before holding his sides in pain. It was then he began his long trek up the mountain, he knew he had to be quick, whoever these people after him were he could tell that the red haired guy and the silver haired women in the maid costume were powerful and in his condition he wasn't much of a match for either.

Hours, hours went by as Natsu climbed up, he figured the higher up he got the safer he'd be, he'd gotten very far in his condition and was at least 7 miles but now the weather had gotten fierce and had brought in a bad blizzard. If Natsu didn't find shelter he was as good as dead. Thankfully luck was on his side as he saw a cave mouth through the blizzard, either that or all the knocks he had received to the head from Erza were coming back and causing him to hallucinate.

Slowly but surely Natsu made his way to the cave entrance, as he got there he leaned up against the wall slowly edging his way in and using the rocky surface for support, he looked around and saw no one. Eventual he slumped down onto the cave floor curling into a ball breathing fire into his hands to keep himself warm. He was ignoring all his other senses at this point as he was solely focusing on staying warm, all his awareness to other presences became zero. So much so that he didn't hear footsteps or breathing, sense the presence or smell the scent of the other individual in the cave.

Eventual Natsu rolled onto his back, his breathing was now more frantic and he was none the warmer, he needed some fire to replenish his magic or if he was willing to risk it something similar to fire, heck he would be willing to try lightning right about now. "Eh who there?" Natsu asked weakly before grimacing in pain as one of his injuries opened up and started bleeding "Fuck that hurts like a bitch!" Natsu cursed with much profanity.

"Who did this to you Nyaa?" Natsu heard a gentle female voice asked from the dark of the cave, which was followed by the sound of footsteps, "Nyaa?" the dragonslayer thought to himself in slight confusion wondering why this person sounded like a cat. The footsteps stooped causing the pinkette to look over and he could indeed see two very entrancing cat like qualities about this person. Although the only visible part of her body was bottom of her slender legs Natsu could her almost glowing hazel, slightly amber cat like eyes in the darkness of the cave.

"A demon from the book of Zeref called Mard Geer" Natsu said with venom, "Zeref never heard of him" the voice responded in a completely clueless innocent tone, this shocked Natsu to no end. Even though many people didn't know that Zeref had returned everyone knew who the most evil wizard in the history of Earthland was. It was then that it hit Natsu, "Memento Mori!" by the way Mard Geer described the effects of the curse there was no way their fight could have taken place because both of them should have died.

The owner of the voice could see a very distressed look on Natsu's face which got her attention, "are you all right, how bad are your injuries?" she asked before walking forward revealing her face and the rest of her body to Natsu whose eyes widened at how beautiful she was. She looked to be around the same age as Natsu, long silky black hair and a pair of black cat ears? Well that explained the Nyaa, well Natsu has seen less believable things.

Her legs were long and thin and she wore a black and red trimmed kimono that slid down her shoulders revealing a large amount of cleavage of her very large breasts under which she wore a yellow obi that had golden oriental balls that accentuated her breasts making them look bigger than they already were. From behind the kimono sprung to black cat tails, all in all Natsu was speechless for the first time in his life a girl had left him speechless just with a simple look.

Quickly realising that he had remained silent for a while lay down allowing for the teen to get a good look at his well-built body and the scars that littered it, "Um yeah Well after I killed him I was up pretty high and I black out so I don't know how bad my injuries got after that but I know that two of the ribs on my left side are broken as well as one on my right side. My right shoulder blade in fractured and my chest feels like jigsaw other than that there this" Natsu summarised before pointing to his open wound.

"If I help you how do I know I can trust you?" the feline girl asked as she looked at Natsu with a cold and calculating gaze, "I don't know why you'd ask that and I don't know what I can tell you to make you trust me. But please I need your help, I don't know what I did but I'm being chased by some crimson haired weirdo and flying maid" Natsu said as his breathing sharpened. This caught her attention "You're on the run from Sirszech himself what the hell did you do violate his sister" the stranger joked before she held a hand over Natsu chest and a soft blue light emanated from causing his breathing to return to normal.

"Thank you and no, from what I could hear he went to place something called an evil piece inside me. I was sort of half-awake at the time but as soon as the thing touch me I went mad and crushed it before making a run for it, that's how I ended up here" Natsu explained causing a shocked look to spread across the strangers face.

"So what you're saying is your body rejected the evil piece, then that means you're not a devil, what are you if you were able to defeat a demon?" she asked in slight fear as she back away from ready to attack Natsu who was now forcing himself up. "I don't know what this devil stuff is but I'm a human wizard, a dragonslayer to be precise. I don't know how exactly I ended up wherever here is fighting Mard Geer but I did and I can't go back home to friends and family I have nowhere to go and judging by the way your acting you're the same" Natsu explained seeing the look on her face however the last part caused her eyes to widen like saucers.

"What how?" were the only words she could utter as her surprise was getting the better of her," I've been through a lot, even though I don't know your name or even what's happened to you in your life I now the look of someone whose willing and whose had to sacrifice something for someone they care about believe me I've been there" Natsu said in saddened tone and with a down cast expression. That expression spoke to her more than any words could why? Because she had worn it many times herself "Kuroka" she spoke up, "Sorry?" Natsu asked not understanding what she meant.

"That's my name Kuroka Toujou" the now known Kuroka answered in a quiet voice thinking Natsu wouldn't hear her but damn his dragon hearing. "Oh that's a pretty name, name's Natsu Dragneel nice to meet ya!" Natsu spoke in his usual cheery tone before accompanying it with his usual smile which caused Kuroka's heart to go 90 "S-sure, well whether I trust you or not is still another thing. Quite frankly I don't know what to believe on this whole just human and dragonslayer business" Kuroka replied trying to act like she wasn't at all affected by his smile.

"That's okay didn't expect you to but aren't you cold up here in just that because if there you could heal me or had some fire or something like fire I could replenish my magical supply and then we'd be warm until the storm passes" Natsu explained while gesturing to Kuroka's rather alluring outfit which may not have been the skimpiest or even the most revealing he's ever seen but it was definitely up there in one there along with some of the most attractive one's he's seen. "How so Nyaa?" Kuroka asked as she moved back closer before laying Natsu down on the ground and clapping her hands together which were then surrounded by a strong light blue glow. (A/N: I'm probably describing a totally different thing her but I trying to describe senjutsu because of what it is it would have this sort of use)

"Well dragonslayer's can eat their own elements, im a fire dragonslayer so I can eat fire but I can't eat the fire I produce myself. When my magic is actually working properly my body temperature is higher than that of a normal person's and I can increase it as much as I want so usually cold places aren't much of a bother but when I'm low on magic or badly hurt like now I can't regulate my temperature properly. However an added bonus of being a dragonslayer is my wounds heal faster but I can't say the say the same for broken bones hehe" Natsu said with a small laugh.

"Well let's find out if you're telling the truth Nyaa" Kuroka said with a small smile on her face, "But how are you gonna heal broken bones in a few minutes?" Natsu asked as if Kuroka was crazy, "It's called Senjutsu it lets me control the flow of chi in your body and I can use it to heal you and combined with your so called advanced dragonslayer healing abilities it should heal you hopefully in a few hour tops kay" Kuroka said before placing the ball of blue energy on top of Natsu chest. The slayer had to grunt from the initially shock he was feeling as the energy entering his system, when energy completely entered Natsu he saw Kuroka doing some intricate hand movements and felt as if with every movement something was being manipulated.

Ten minutes passed and Natsu could feel some of his pain being relieved but it was then that he almost had to bite down on his to silence the roar of pain as he felt his bones slowly shift back into place and heal up. The pain was excruciating, worse than any pain he had ever experienced in his life, "If it gets to be too much for you just say" Kuroka said looking at the pinkette in pity, "No, if we can…AAAHHHH…if we can fix my ribs I should be good" Natsu grunted through the pain gaining a nod from Kuroka before she continued her hand gestures.

A few hours later

It had taken longer than anticipated but it had worked, after it gotten to the point where Natsu could no longer take any pain he had Kuroka stop, thankfully his ribs were practically completely mended, his shoulder blade was fixed and his chest was only mildly bothering him. Now Natsu was able to feel his magic again but he could also feel something else but he could figure out what that was later.

"Is there anything in here we could burn and make a fire or am I gonna have to turn myself into a human heater?" Natsu asked as he leaned against the cave wall. "Well I want to see that all this dragonslayer business wasn't just a load of crap so you may begin heating yourself up" Kuroka said as she plopped herself down beside Natsu who now had a look of concentration on his face, sure as the day she was born she could feel the heat rising and the closer she got to Natsu the hotter it became. "This warm enough for you?" Natsu asked in a smug tone causing Kuroka to pout her lips in response. "No need to be so smug about it" she said in an upset manner.

There was a moment of silence "So what are you going to doing after this. I won't ask what you did or for the reason why you did it Kuroka but you'll have to face it eventually" Natsu said as the black haired beauty suddenly clung to his arm and began shaking. "I know, I've always known that I'd have to face what I did I just never wanted to so quickly I just don't know if can…I'm scared" Kuroka said in a frightened tone as a few tears slipped down the side of her face. Natsu hated when girls got like this especially the way Kuroka was going on right now, from what he could tell she was a strong person but the way she was now reminded him too much of Erza at the tower of heaven.

Natsu then one of Kuroka's hands in his own surprising the teen, "Kuroka whatever you sacrificed was obviously for someone you cared about deeply, I don't know what it was you did but I can already tell your afraid to face whoever it was for." Natsu said in a gentle tone before pulling her head close causing her look up slightly to see a small smile on Natsu's face "That's why I'll help you along the way so you can face this person" Natsu said in the same gentle tone causing a look of surprise to spread across Kuroka's face

"Why, we hardly know each other?" Kuroka asked in an alarmed tone, why she was one of the most wanted criminals in the underworld and a stray devil so she would always have someone after her why would he want to help her. "Do I need a reason to help someone?" Natsu asked in an amused tone to which the Nekomata didn't find so amusing. "When it's someone like me your helping then yes, yes you do!" Kuroka half shouted in response as she locked her gaze with the dragonslayer's

"Fine if anything I can see that you're suffering and I want to help you with that but more so than that I can relate to the fear of facing up to someone you care about, for seven years it truly destroyed me I don't want the same thing to happen to you, and you seem like a really good person" Natsu in a sincere tone.

All of his words even though spoken with such a gentle tone felt so powerful they just wanted to make her break down and cry. "You're a strong person Kuroka but even if that's the case that doesn't mean you aren't allowed to cry, it doesn't mean you have to bottle up your emotions" Natsu then continued in the same tone before Kuroka let the water works flow for a few minutes.

After a few minutes Kuroka had settled down although the use of her Senjutsu had finally taken its toll and she was now sleeping comfortable against Natsu shoulder causing the slayer to smile before he too soon found his world darkening.

"Night Kuroka"
