Warning large A/N ahead. To skip search for the "A/N End" in the document. To those interested keep reading.

Okay, so after a recent brainstorming session induced by another argument about the horrendously bad outcome of the Gaara vs. Toph DB I ended up theorycrafting and came up with a story concept I find quite interesting but do not have the time to pursue, since I already have my hands full with just two stories.

This is why anyone that is willing can accept this challenge and keep expanding on it.

The challenge is titled "Naruto: Master of Yang chakra."

Yin and Yang chakra are the basis for all non-elemental techniques and manipulating the ratio of these energies is the basis of the Hiden jutsu-type, pretty much what the Nara and Akimichi are using.

The body expansion jutsu is nothing more than using Yang chakra to manipulate ones own body. Since Yang chakra is the source of vitality and life it also is able to imbue objects with a life on their own, like Sai's ink creations. Lo and behold he has the ability to use Yang chakra.

So I dug deeper to look for other body altering techniques. We have Konan's Shikigami no Mai, Orochimaru's soft body modification, Nagato's Asura path and the Hozuki clans hydrification technique.

Konan is able to manipulate yang chakra so it is likely that similar to how the Akimichi use Yang chakra to expand their bodies the Shikigami no Mai manipulates Yang chakra to turn ones body into sheets of paper.

Orochimaru is capable of using Yang chakra as well going by his various regeneration techniques and it fits with his ability to elongate his body like rubber, similar to an Akimichi's body expansion but in a more fluid way.

Nagato, after having been ressurected by the Edo Tensei, did use the Asura Path to transform his body into a mechanized form which means the array of weapons on the Asura body was not an original part of the Asura body or somehow grafted onto it post-humously. The Rinnegan gives the user control over all five types of nature transformation as well as Yin-Yang chakra. For example as seen when Madara enhanced a Ranton technique with Yin Chakra. Meaning that it can be mixed with nature transformations(basic and advanced).

Finally we have the Hozuki's Hydrification technique which turns their body into water.

Gengetsu, the second Mizukage, can use Yang chakra as well which would explain why his hydrification technique is much more versatile than what Suigetsu and Mangetsu have demonstrate. For instance his water body is mixed with oil.

Therefore it is my believe that the Hydrification technique, similar to other body modification techniques works on the basis of Yang chakra and simply mixes it with Suiton nature transformation to alter the bodies cellular structure to match that of water.

Therefore iit should be possible using Yang chakra and knowledge of a specific substance (like paper) or in combination with elemental chakra to alter the body into anything imaginable.

Basically a Naruto character sufficiently skilled in both of these should be able to turn their body into any of those elements. Pretty much similar to any logia style devil fruit users from One Piece(minus the no swimming).

Now we get to some basic information about the starting point and some other basic information. Aside from that you may deviate from canon as much as you want.

The story starts during the chunin exams second task. Naruto gets slapped on with the Gogyo Fuin like usual but instead of being just unconscious he meets his darker half, the representation he fought in part 2 to master the Kyuubi. However this dark naruto is not quite as angry and agressive as the one three years later. He explains to his counterpart the nature of their relationship and how repressing everything and segregating it is bad for him and how much he resents his other half for enjoying life while he has to spend his time stuck in the recess of Naruto's mind unable to experience life to the fullest.

So he proposes a merge between them, telling Naruto it would be more benefiting to him if they weren't split and in all his naivety and believe in the good of people Naruto agrees to it.

This of course has consequences for his behaviour. This merged Naruto is much more distrusting and wont simply deign anyone a friend that hasn't behaved totally shitty or that he knows personally. He wont jump to the assistance of just anyone and he will be confronted with everything he tried to repress. Anger, hate, self-doubt, indifference, apathy and so forth.

You can toss up the chunin exam fights if you like(both preliminaries and finals). No need to follow canon here. In fact I encourage you to do so.

Cue prelims ending he confronts Kakashi who, of course, is informing him that he is not going to train him and tells him of Ebisu. However unlike canon Naruto he is not going to spend time trying to convince someone that instantly deemed him "not worth his time" and, even if a bit grudgingly, accepts Ebisu's help without complaint. Afterall someone that's willing to help him, even forced, is better than someone that doesn't even want to help him.

So Ebisu will still end up explaining Naruto about Chakra but thanks to his more subdued nature, thanks to his enthusiasm and exuberance being curbed by colder emotions, he actually takes time to enquire more about it leading him to find out about Yin and Yang chakra along with the five elemental chakra natures.

From there you can choose on your own how he discovers his ability to proficiently use Yang chakra and what kind of ability he will 'create' first.

That's just about the basic gist of what I imagined.

Pairings: No Shounen-Ai/Yaoi/Slash etc.

Hinata and Sakura are completely off limits to be used. Ino and Tenten are discouraged from being used for the pairing as well.

Aside from that just about everything goes. Even Genderbending another male into a female is okay as well.

Bonus points for a Harem, Tayuya, Karin, Mei or Kurenai.

Whew. That was rather long. Thank you for everyone willing to read through that and especially those that are interested in accepting this challenge.

A/N End

Now then read and enjoy this chapter.

Also for those that are somehow squeamish or sensitive to these things, this chapter does contain mentions of rape, mind altering substances and a lot of unsavory things. Those that find themselves unable to deal with topics of that kind should either skip this chapter or the parts pertaining to it.

The two mages, Erza 'Titania' Scarlet and Naruto 'Crimson Reaper' Uzumaki who, currently, was masquerading as 'Thousand Master' an independent mage under the apprenticeship of Jiraiya, had just entered a fort filled with demons.

They were on a mission to rid the city of Hagure of their demonic problem that had been plaguing them for a month. While they had merely encountered a few imps, an incredible pesky but otherwise very weak type of demon, and fel hounds, a vicious type of canine demon that fed on magic and was excellent at sniffing it out. Usually neither of these type of demons was much of a problem on their own, at least not enough to warrant an S-Class request. However there was something much more sinister behind these demons. Erza had encountered a large, unknown type of demon that had halted her pursuit of some fleeing fel hounds. Many women had disappeared and likely been kidnapped by the demons and the city itself was shrouded in a dark feeling of depression and hopelessness. Something dark was hiding in the shadows, observering and lurking. It was waiting for something, biding its time until the time was ripe.

Naruto very much suspected the shrine elder to have a connection to it. The old man just had a strange aura about himself and it was strange that Erza had not sensed anything similar. On top of that the old man's interactions with his surrogate granddaughter, the shrine maiden, Yayoi were quite strange as well. It was well hidden but to someone like Naruto, who had hidden a lot in his already short life, resorted to frequent lies and had the knowledge of men many times his age at the disposal, it was something he was able to notice. The young miko was clearly uncomfortable in the presence of Taigon, the shrine elder and Naruto clearly suspected the man to be involved with the demons.

'But it's not like I could just accuse him like that.' the blonde thought sighing silently as the torches on the wall flickered, shedding their dim light inside of the building. It was a real testimony to the age of the fort as it used neither light lachrima nor did it use any electrical light.

They were now in a larger hall which offered them the quite a few option as to where to go.

Two large hallways stretched to the left and right of the room, another large door, similar to the one they had entered through, was in the north of the room. Two sets of stairs were spiralling up to the second floor and down to the basement. These two sets of staris were in the northwest and northeast corner of the room.

The room itself was decorted with a frayed carpet of a faded red and golden colors. Two old and rusted knight armors 'guarded' each of the hallways and the large door in the front of the room.

There were a lot of options for them to choose.

"Where should we be looking first?" Erza consulted her partner, her tone cold and her question short. The scarlet haired woman was still a bit annoyed that her partner for this mission choose to have so little trust in her combat abilities that he would willingly take a very unusual but potentially very debilitating attack in her stead.

Naruto had a pensive look on his face as he mulled over their choices "My guess is that they probably keep their provisions down in the basement." he gave a cursory glance towards the pair of stairs leading down "Top is likely where the leaders are."

"Then we should strike there, should we not?" Erza suggested, sounding eager for battle, to finish their job and take care of those vile demons "Cut off the head and the body follows."

It was a valid strategy and in most cases it would probably work.

"That is if they didn't have hostages." the blonde reminded his partner whose face grew stony at the reminder of the missing women "While they do have use for the women it is probably not beneath them to use them to force us into surrendering."

While he personally could care less about them people themselves he felt sympathetic for their situation. His own childhood had been ruined as a result of a demon and now he had devoted his life goal to the eradication of said demons creator. While it was unlikely that anyone would lead a childhood like his if the demons did as he suspected their lifes would still be significantly affected and not in a pleasant way, since people tended to fear and ostracize those that were different or that they did not understand.

"You are right. Then we should first find anyone that might need to be saved." Erza stated and looked in between the two corridors. For all intents and purposes they seemed absolutely identical. She gave a small shrug "You go and take care of the west side of the fort, I'll take care of the east." Erza stated and received a small nod from her companion. The 'Thousand Masters' cloak billowed behind him as he walked through the entrance to the western corridor. On the other side Erza had walked through the door to the eastern corridor.

"Clever little mages, aren't they?" the lord demon of this fort commented with a certain amount of amusement in his words but once again the demon next to him did not respond "Well it's not like we would need to hold the girls over their head." he gave a dark chuckle as he kept watching the pair

The Vanguard next to him inwardly rolled his eyes at his boss' antics. Why did he have to be so theatric? All he wanted was a good fight and here he was squandering the potential of the red haired swordswoman by having her fight small fry. A small shiver of anticipation surged through the body as he imagined the magnificent clash of blades they would have.

That was the only moderately interesting thing right now. The other magic user did not interest him. His body looked scrawny and weak. With a single glance he could tell that the cloaked one had never used his body to fight, hiding behind fancy blasts of colorful magic to do his deeds. In the demon's eyes he was a poor fighter that did not deserve his respect nor did he deserve his attention. The person under that cloak was no true warrior. Only those that used every ounce of their body, clashing fist to fist, head to head, weapon to weapon until they were bloody and scarred were the ones that could be called a warrior.

"Let us see how long they are going to take advancing through my 'Bizarre Corridors'." the first demon asked himself and snapped his fingers, springing the traps that had been placed in the corridors.

As soon as the pair had entered their respective corridor the doors between them slammed shut, cutting them off from eachother.

Naruto gave a small glance back towards the closed door which was probably secured by various magics. He should have expected a trap like that but not that there was any point to go back right now, his objective lay ahead. He took another step and suddenly the ground beneath him lurched. The walls, the ground, the ceiling, everything shifted and morphed. The corridor twisted and turned into a bizarre piece of architecture. Stretching far beyond what seemed logical, some stretches suddenly seemed to drop off like a fall from a cliff and other parts reached far up like a steep climb.

"How annoying." Naruto grumbled with a frown as he suddenly noticed that he was upside down and walking on what previously was the ceiling.

There was quite a lot of magic around him. It suffused every part of the stone around him.

The demons had probably adapted a shelter function of the fort for their own uses but instead of leading those inside, that were unable to fight, to safety it was meant to confuse and exhaust intruders.

Naruto kept walking forward but he found it very disorienting to be upside down. He imagined that this trap would probably suck for those that were prone to vertigo.

The blonde kept walking through the twisting and turning corridor. He jumped down into cliff like drops and jumped to opposing ninety degree like walls only to walk on them just fine. It was indeed a bizarre and strange area and with each passing moment Nartuo felt more and more annoyed with the situation however he knew that losing his composure right now would not achieve anything at all, except maybe waste valuable time and energy.

"Gyahaha!" he heard the high pitched, gurgling, giggle of some imps. They were nearby, at least going by the volume of their voices "Stupid little human. Can't even get out of here." one of them commented

"I wonder, I wonder..." another seemed to muse and a third seemed to finish the second one's thoughts "How well will he burn?"

Mad cackling erupted and Naruto failed to count how many he would be dealing with. He was simply unable to keep the horrible cacophony of their voices apart from eachother. Each imp sounded similar to the next but that was the least of his problems. While he heard one distinct explosion, telling him that one fireball had exploded straigh in the imp's hands, the fireballs of the rest worked just fine.

'Where are they coming from?' Naruto thought to himself as he tried to sense the origin of the magic as he could not rely on his sense of sight. Just in time did he notice a rush of hot air coming from behind him "Shield of Water!" he quickly spun on his heel and raised his hand into the air. Water surged as his magic was activated and a circular shield of water was errected in front of his body. Invisible flames impacted against his shield and sizzled out as hot steam poured into the air. However while the impact had undoubtly so come from behind him then how was it that the orange fireballs had headed from the opposite side from him?

If the magic did indeed twist the walls around him physically then that did not make any sense, there should be no disconnection between the image of an attack and the attack itself.

Naruto used the remaining water of his shield to send a Water Burst down the back in the hopes to catch the imps but it didn't seem to do anything.

In fact the imps giggled at his attempt to attack him "Stupid, stupid human." one of them taunted him but it apparently wasn't capable of thinking of an insult beyond stupid and human.

"Still can't figure it out." another one spoke tauntingly and laughed hysterically

"Me thinks we should give him a hint." a third one giggled and joined his brethren in his frantic laughter

"Little humie needs to learn." the whole group said in a singsong "Needs to learn pain." Suddenly a black figure lunged from the ground towards him "Great Breakthrough." in reflex he shot a blast of wind towards the small imp, only to curse himself as he had fallen prey to the machinations of the corridors strange magic. Just as the image was about to strike his legs he felt a weight on his back and the sharp, claws of the imp dug through his clothes into his skin. Naruto ignored the sharp pain coming from his back as he had felt worse than that.

He gave a smirk beneath as the imp drew his blood "Blood spike." Naruto intoned and the blood the imp had just drawn plus some which Naruto drew out of his skin pierced through the imps head. The body of the imp went limp and fell to the ground. He heard the thud behind him but the imp clearly fell down in front of him.

'If this trap doesn't change the real position of an object then it has to be some kind of illusion.' Naruto concluded and realized the trick behind this corridors traps. Perhaps the fort once really had a shelter function like he had initially assumed but the demons or specifically the demon in charge of all these imps definitely had it repurposed.

"Golems Fist!" a rock fist rose from the ground and his smashed it into the wall. The stone around him shook but did not yet give way.

Naruto had the rock fist keep slamming into the wall while he was going to keep defending himself from these pests.

"Kill this stinking human!" one of the imps had roared after they had gotten over the shock of one their brethren dying after seemingly having the human in his grasp.

Naruto blocked another barrage of fireballs. This time none of the imps magic had backfired. In retaliation Naruto pointed the palm of his hands in each direction and fired a Great Breakthrough down each corridor. The blonde mage had only heard a few cries of pain but that was still very satisfying to have eradicated another few of these pesky demons.

He glanced over to the stone construct which was still hammering away at the sturdy stone 'Apparently the walls are thicker than I anticipated.' the blonde mused and fired a blind blast of light behind him which elicted another cry of pain from an imp as it was slammed into the wall. Suddenly the area flickered around Naruto causing the blonde to smirk.

Behind the thick wall was a thing layer of a crystalline substance, lacrima. When the trap was sprung the lacrima drew ethernano from the air to power the illusory spell. It didn't change the position of objects or rearrange the corridor at all it just changed the perception of those caught within. Up could be down and left could be right or maybe right was up and down was left. All these were myriad of possibilities and if he had not tricked himself into thinking that the actual physical position of objects had changed he would have very likely noticed the trick behind it much earlier.

"All right time to shatter this fake imagery." the golem's fist slammed once more into the wall and shattered the lachrima. Just like the lacrima had shattered so too did the world around Naruto seem to shatter. Now that his perception was back to normal he saw that had not gotten very far from the entrance at all. The looping and twisting corridor had likely led him back and forth.

But now it was time to take care of the rest of those pesky imps. They were straight in front of him, about thirty remaining. All of them had small balls of fire in their hands, ready to be launched at him "Oh no you don't." Naruto grinned beneath his hood "Storm Shred." countless blades of wind ripped through the air and the weak imps stood no chance as they were ripped apart, one after the other. Their green ichor spilled over the ground and without any care Naruto kept walking, ignoring the corpses completely.

"Looks like the hodded one solved the mystery." the dark voice of the demon's boss commented idly "Well, I wonder how his pretty companion is doing." the demons dark eyes widened for just a little bit "Why is she entirely unaffected by the Bizarre Corridor?" he asked with slight amounts of anger as he saw her rushing towards the direction of her partner "She should be stumbling around in confusion just like her partner."

Moments before

Erza instantly turned around as she heard the door behind her slam shut. She would probably be able to slice through it with her blade. This was obviously a trap meant to stall and stop any intruder. However she was not going to hurry around and rush to her partners side just now. Not as long as she had a task to accomplish. Even if her partner didn't seem to have complete trust in her ability to handle herself she trusted him to be able to handle himself.

Erza was shook out of her musings when she felt magic being used. The world around her twisted and turned and the area around her was scrambled. The corridor was elongated and many strange and impossible intersections had formed. However the area in front of her seemed to be quite blurry, as if it was a poor quality image. Something that was not at all real. Where had she seen something like this before?

'That's right!' Erza realized 'The 'Thousand Masters' projections.' the projections he had used to illustrate his lessons about demons had seemed quite blurry to her as well but why? Then a grim reminder hit her. She had lost one of her eyes. It had been replaced by an artificial one and she had no problems seeing through it but apparently it was unaffected by fake images. She closed her natural eye and the blurriness disappeared and was replaced by the straight and completely normal corridor. If not for her artificial eye she would likely be stumbling around for a long time which would give anyone that desired ample time for an ambush. She hoped that her partner was able to deal with this devious trap.

"No time to waste." Erza muttered as she realized that if her partner was unable to deal with this illusion he would likely need her help. While she normally was not someone to think like that but for a brief moment she felt a smug sense of satisfaction course through her body at the thought that she would be able to show the 'Thousand Master' that she was very well capable of taking care of herself. Erza quickly shoved those thoughts out of her head. She had no right to think like that when the situation at hand demanded absolute concentration. So with one of her eyes closed she rushed down the corridor. Every now and again she came across a door which Erza opened only for nothing to be behind the closed doors until one door in particular.

She touched the doorknob, intent on opening it, only for the door to burst open as half a dozen fel hounds barged through the door, drooling their acidic saliva onto the ground where it hissed and sizzled as it came in contact with the stone. Past the door she could make out many more of the fel hounds, they were facing towards her. The demonic dogs were in some sort of kennel. Pieces of bone which had not been dissolved or eaten were strewn about the floor.

'This is the place where they are keeping these vile animals then.' Erza dodged an incoming glob of acid which impacted on the ground a good deal past her. Inside the corridor dodging the balls of acid the dougs could spit at her was going to be much more difficutl. She somehow needed to get into the more spacious room where she would have an easier time dodging the attacks of the fel hounds.

She requipped her flight armor for the speed boost to get past the group of fel hounds that had surged into the corridor and were viciously growling at her. She sliced through some of them in passing as she rushed into the room. All of the fel hounds were eager for her potent magic power and had surrounded her, just like she had wanted it.

"Requip: Heaven's Wheel Armor." she called forth her armor from her requip space and in a flash of light she had changed from her leopard like armament into a much different kind of armor. The whole armor was made from silver metal. The upper part of the armor was merely a small breastplate composed of feather shaped plates that pointed upwards with a metal flower on the front which extended along her hip. Her biceps were covered in metal straps and very large plated gauntlets that sported feather shaped plates at the edges.

Her waist was circled by large, decorated plates reminiscent of feathers that lie on a long skirt. A pair of plated boots covered her feet and were partially hidden under her skirt. The armor also formed a neck guard made of feather like plates and a tiara with metal wings and from her back sprouted two pairs of large metal wings.

In her hands were two simple one-handed swords with blue embellishments along the blade and a feather shaped handguard.

This armor was ideal for facing multiple opponents as it allowed her to summon a large amounts of swords and use them as projectiles or as follow up slashes to her swings.

She summoned dozens of blades around her. One of the dogs extended its drain tentacle towards her but she wasn't going to be caught off guard by an attack like that. With a quick upward slice of the blade in her right hand she cut the appendage off causing the demonic dog to wimper in pain but she would show these creatures no mercy. More fel hounds began to attack her and began to swarm towards her in droves "Dance my blades!" Erza commanded "Circle Sword." the dozens of blades whirled around her like a tornado of death. The fel hounds which were closest to her were cleanly sliced apart into tiny pieces before the swords shot forth around her. The virtual armory of blades cut, sliced and impaled everything that stood in its way leaving naught but corpses in their wake.

Erza requipped back into her normal armor and surveyed her surroundings. Aside from the many fel hound corpses which now littered the floor of the kennel the room was virtually empty. At the very least no human was anywhere around here.

"I better get to the 'Thousand Master' maybe he had better success finding the missing girls."

Erza shot towards the way she had come from. When she came upon the closed door she easily cut through it and rushed to the other side of the large entrance hall. She cut through the door barring her entrance to the western corridor and then tried to find her partner as fast as she could.

Soon enough Naruto came across a door. While not particularily out of place or strange the blonde could hear sounds coming from behind the door. At first he thought they were sounds of pain but then he realized the truth.

'No.' Naruto thought grimly and reminded himself that it wasn't pain but pleasure 'This is probably where they keep the women.'

He briefly wondered if Erza had already dealt with her side.

"Did you find them?" he heard the scarlet haired mage's voice ring out from behind him and he turned around to see that she was indeed standing behind him

He had hoped that he would be able to do this by himself but it seemed like his luck wasn't that good.

"They are behind that door." Naruto responded and Erza's gaze hardened, as she readied her blade for battle

"Then let's do this." the Fairy Tail mage declared confidently and Naruto gave a stiff nod as he opened the door. He gritted his teeth at the scene in front of him and he could feel Erza growl in anger. He could feel her anger roll off her in waves. He noted her large crimson magic aura around her as she stalked into the room.

It was truly repulsive what the demons had done. In the room were the girls which had been kidnapped from Hagure. They were lying on the ground, some completely naked others wearing the barest shreds of clothing that they still had on.

A few of the girls were staring blankly into space in a sort of delirium, completely oblivious to the fact that some imps were ramming their penises in and out of their vaginas.

Others were moaning lustfully as they pleasured themselves, eachother or were once again made use of by some of the demonic beings. Only very few of the girls actually seemed to be distraught by what was happening to them. They had huddled together, away from the more apathetic or lustful sort. Some were close to tears others had red and puffy eyes from having cried while some were mumbling prayers for help, hoping that anybody would come and save them from this nightmare.

Another thing which a lot of the girls had in common were large distended bellies, not from being fat but an obvious sign of pregnancy. In order to make their demonic forces grow in size they had used the kidnapped girls bodies as breeding stock and it had worked quite well. Pregnancies between most demonic beings and humans always resulted in a pure demon being born. There were some exceptions mostly concerning more humanoid demons like Incubi and Succubi which could actually produce half demonic offspring.

But imps they bred like rabbits but worse. Since they were so weak, they needed to compensate with numbers. Therefore each pregnancy between an imp and a woman would result in about an average of five newborn imps.

The time needed for a complete pregnancy to occur was about a week give or take and on top of that imps grew rapidly fast. In another week after they were born an imp would have reached full maturity. But something every single girl had in common were changed features. Every one of them seemed to be shrunk in some form. In some cases the girls were just as tall as the imps themselves. Their skin came in various shades of coloration. Some had a vibrant red skintone others a more orange-ish and others purple or blue. All of them also had horns. Some larger ones like imps and some just small stubs like they were just growing.

Naruto gritted his teeth as he realized that in perhaps another two weeks the imps could have probably overrun Hagure when combined with the fel hounds, the unknown demon Erza had encountered and whoever was their leader. Between Erza and himself they had probably killed about sixty, maybe more, maybe less but around there in numbers, imps. Seeing the amount of girls they had kidnapped and counting the pregnant ones among them there was easily another seventy five to hundred imps waiting to be born. And in two weeks that number would have been doubled. Imps were very weak and in their usual numbers no problem for even the most bumbling fool of a mage but take a hundred fifty, two hundred or more and couple that with what other dastardly demonic creature was crawling around here... well Hagure would have been reduced to a stronghold for demons.

While Naruto was caught in his musings Erza screamed in rage. This situation it reminded her of when she was a slave in the Tower of Heaven. They had not been raped or sexually abused but these demons had reduced these girls to nothing more than a resource to be used at their will. Just like the slaves had been reduced to nothing more than an expendable workforce to facilitate the ressurection of Zeref.

A warcry of range rang out through the room. Those girls who were still conscious enough and still aware enough turned towards the source of the voice and saw the armored girl with an angry red aura. The imps, occupied or not, turned to the source as well, sulfuric eyes wide in shock. In a matter of seconds the raging fury of Erza had been brought down on them. Every single of the demons had been brutally beheaded by the wrath of the Requip mage. Eventually Erza stood panting in between the girls as the anger left her system, her sword stained with the blood of demons and the ground littered with their corpses.

The girls that were too far gone continued to stare off into space, unconcerned by their saviour. The girls who had previously been fucked by one of the imps moaned in disappointment at the loss of a penis inside of them and went to finish themselves off through masturbation. While the newest girls who still tried to resist were crying as they rushed towards Erza and slung their arms around the armored girl.

"Thank you, thank you, thank you." they bawled and sobbed into the cold steel of the mages protection. Erza let her sword clang to the ground and pulled them close "Everything is going to be okay." she comforted them. Their nightmare days were going to be over, she was going to make sure of that.

"I-I t-thought we were going to stay here forever and...and..." she tried to say become like them but the words died in her throat as she once again broke out in tears.

Erza pulled away from their hug and pulled forth a few spare clothes out of her requip dimension "I don't know if they are going to fit but at least you are going to have some clothes." she handed the spare clothes to the naked girls who quickly got dressed in the comfortable cloth "I want you to get away from here and get back to Hagure. Do you understand?"

The girls nodded and glanced at some of the girls on the ground "What about the others?" they didn't seem to be concerned with getting up or doing anything at all

"We wont be able to take them back to town like that." Naruto finally spoke up and the girls looked at the cloaked boy "Go back to the town and request for some people to help. When they get here we should be finished with the rest of the demons that are still here."

His tone wasn't quite as cold as he thought it would be. Perhaps the empathy for their situation had tempered his anger for the demons better than he had believed it would.

The girls nodded silently and ran out of the room as fast as they could so that they could leave this place and the events that had transpired here behind them.

"I can't believe this." Erza finally muttered in shock as she looked at the other girls who were either unresponsive or caught in pleasure "How could this happen? They aren't acting normal at all more like they are under some sort of drug."

Naruto picked up a small wrapped parcel from the ground and opened it. In it were two reddish pieces of bread, reminiscent of toast. The two pieces of bread were very soft to the touch and in between them was a strange piece of meat that looked dried out but still seemed completely soft and juicy. He held up the strange sandwich "This is the reason." a sickly sweet smell wafted off the unwrapped food. It compelled him to eat it, to taste the delicious and moist bread and tear into the tasty meat inbetween but at the same time he could feel a sense of wrongness surrounding the food like a sense of foreboding that nothing would be right if he did eat it.

"What is that?" Erza asked and walked up to her partner and looked at the strange food he held in his hands and she too felt compelled to eat it for a second she though about taking it from him and taking a bite out of the sandwich but realized that it was a stupid idea considering what happened to the girls.

"Impfood." Naruto merely stated and with a quick application of fire magic he roasted the sandwich to a pile of ashes

"Impfood?" Erza tilted her head in confusion. She had never heard of anything like that in her life

"Did you read Alice in Wonderland?" he asked her and Erza blinked before nodding. It was one of the first books she had read after coming to Fairy Tail, to unwind from training and missions.

"Demon food is like all those things Alice eats but worse." the blonde explained "Demons have their own type of food you know? They induce all sorts of strange things in humans, especially bodily transformations." he elaborated "This is because all kinds of food and drinks of demonic origin are inherently magic in nature. They are not created by any normal process, like you would bake a bread or press juice."

"What kind of effect does Impfood have? Why are the girls like that?" she asked raising her voice in anger before she lowered it again "And can we do anything for them?"

Naruto gave a sigh "Impfood... well it's the reason most of them are like that. It raises your desires and lowers your inhibitions. In the beginning the desire is going to bother you, eventually you give in and seek to get rid of it yourself, then one is going to actively seek out a partner to get rid of it and finally a human that has eaten nothing but Impfood for days and day on end... they wont care who or what it is that pleasures them just that it does." the blonde explained somberly "Another sideeffect is that those that consume Impfood turn decidedly more implike. Their skin gains a different coloration, they shrink and grow horns but they wont fully turn into imps." Naruto paused to let Erza process what he had told her "As for if we can do anything for them... Well strictly speaking no. They are going to recover from their catatonic and high pleasure states on their own and as long as they no longer consume any of the Impfood they wont return to those states." Erza let out a sigh of relief that the girls were going to be okay "But as for the changes already done to them? They are going to stay."

"So they are going to stay like...that?" Erza asked with a grim expression an angry frown marring her face and her partner gave a slow nod.

"Yes. They are not going to grow back to a normal height. Depending on how old they are they might still grow a bit like anyone up to a certain age but it's not going to compensate for their bodies shrinking. Their skin is going to stay like that and their horns are there to stay as well."

"That's horrible." Erza could not imagine what it would be like to look every morning into the mirror only to be reminded of what happened like that

"The physical changes are going to be a problem yes." Naruto agreed "But the mental changes are going to be much worse." Erza perked up with an alarmed expression on her face "I told you ALL changes were going to stick. The girls aren't going to be catatonic, permanently lustful, unresponsive and all that but they are going to live with a drastically heightened libido and much, much lowered inhibitions. That's going to be just as debilitating."

'The libido not so much as the inhibitions, though.' the blonde thought grimly

"These demons are abominations!" Erza declared in anger and she could finally understand why Mira hated them with a passion and why she took every single request to get rid of them "Let's get rid of their leaders now! They need to pay for what they have done."

In a lot of ways natural occuring evil demon's were much worse than any of Zeref's artifical created demons. Yes, Zeref's demons were very strong but the demons that had been encountered were merely there to cause destruction and kill. Natural demons were not always as 'merciful' as to kill you.

"I couldn't have said it better." the blonde agreed and the two stormed back through the corridor into the entrance hall. They took the stairs up to the second floor and entered the largest room available.

The two looked to the far end of the room and saw two demons. One of them was seated on a chair and the other standing. The seated one stood up.

"Welcome, welcome, young mages." a cultured voice greeted them with some excitement "I welcome you to our humbled abode or what you have left of it during your rampage downstairs." the demon bowed like an actor on a stage "Allow me to introduce myself. My name is Iratius."

The one that had introduced himself as Iratius had dark blue skin and was about as tall as an average male. He had a pair of horns sprouting from his forehead which cuverd over his head which was covered in long, raven hair. Iratius had a perfectly shaped body which he only covered in a very loose vest. On his back, folded to his skin was a pair of bat like wings. Iratius wore a pair of black pants which presumably had a hole as a black tail hung lazily from his rear. Iratius also didn't wear any shoes as, just like his hands, his feet were clawed.

The unnamed demon however was quite different. He was a large hulking behemoth with light blue skin. The demon was easily taller than two meters. If Naruto had to guess he would put him closer to three and he was about half that wide. The demon was decked in thick armor. His upper body was covered in a cuirass and his shoulders in a pair of pauldrons which were littered with multiple spikes across their length. His hands were covered in thick plate armor and his feet were covered in plate boots. While his lower body was merely covered in a piece of blue cloth that wrapped around his waist and legs. In his large blue claws the behemoth held his weapon. The weapon was large, larger than either Naruto or Erza. The handle of the weapon was wrapped in a leather like cloth and extended like a pole until the actual blade. The blade, at first glance, seemed like nothing more than an unrefined piece of metal but then one could see the serrated and sharp edges that covered the length.

'Like a saw.' Erza thought as she examined the weapon and the second demon had noticed how their eyes flickered to his comerade

"Ah I see you have taken notice of my dear vanguard, Vanitas." the leader of the two demons raised a clawed hand and gestured towards the blue behemoth next to him "Vanitas is my bodyguard. Say hello, Vanitas." Vanitas stayed silent which caused the first demon to sigh "As you can see dear Vanitas isn't the most talkative person."

Naruto gulped. Vanitas was a vanguard demon. Hulking colossi like demons. Their strength was incredible and their endurance even more so. They could masterfully swing even the heaviest of weapons without tiring. They were lacking a bit in the speed department but they had a pretty good magic resistance. This was the reason why they were usually the spearhead of an attack. Their juggernaut like abilities allowed them to tank most attacks with little to no consequence at all and Naruto supposed that it was why he had been chose to be a bodyguard.

"Why all the silence and grim faces?" the first demon asked amicably and pulled out a blue flask with a stopper. He pulled the stopper and raised a glass and began pouring the liquid into the glass. It was thick and viscous but less than honey. With its thick gooey white texture it could only be...

Naruto blanched as he realized what the demon had just poured into his glass. The demon somehow seemed to notice the change in the cloaked boys attitude "Want a sip?" the demon asked with a laugh before he eyed Erza "Or perhaps your companion would like to take a drink?"

"Light Rain." Naruto let forth a fierce shower of light, a surprise attack. The demon seemed so intent on talking that he thought he could get a surprise in but with speed that belied Vanita's size he had appeared in the path of the light projectiles and tanked them. Lesser beings would have likely been riddled with holes or at least been bleeding but the vanguard demon had tanked the light barrage without many problems. All he had received were a few bruises.

"Now, now don't be so hasty." the first demon chided with an amused laugh as he took a sip from his tainted drink "As I wanted to say. But it would mar such a beautiful woman if she were to take a sip from this invigorating beverage."

Naruto was not going to get through Vanitas without bigger firepower, so he would let Erza take care of him when it was time to fight. For now if this demon felt the need to talk that much he was going to let him talk. The more he talked the more information they would gain. Since a surprise attack had failed gathering more information was going to be useful.

After the impfood Erza didn't want to know what kind of liquid the demon was drinking but the thick, white goo looked quite unmistakable like a certain liquid. She knew that during lovemaking some considered it an erotic act and it was often enough depicted in the Icha Icha series but to so casually be drinking it... that was even too much for Erza who seemed to be visibly repulsed by the glass the demon had pointed towards her.

The demon shrugged at her and took another sip of the demonic drink.

"What is that?" Erza asked her curiosity finally winning out and before the demon could respond Naruto spoke up

"Incubi Draft." he explained mechanically and the Incubi laughed and nodded

"Yes, indeed. Well done." he praised Naruto with a smirk "You seem to be quite knowledgeable on us demons and our little assortment of food and drinks."

"Know your enemy and know yourself and you need not fear the result of a hundred battles. "Naruto quoted tersely and the Incubi laughed

"Ah yes Sun Tzu, a classic." Naruto didn't know why the Incubi referred to Sun Tzu as a classic as that usually wasn't something they dabbled in but there already was a lot that had not added up.

"But returning to your question. You wanted to know about this delectable Incubi Draft did, did you not?" the Incubi smirked at the repulsed face Erza was making "Anyone imbibing an Incubi Draft will be given more Incubi like qualities. I suppose you know what our main metier is?"

"Lust." Erza replied immediately and the demon clapped in delight

"Bingo." the Incubi praised "Men will become more well endowed, produce more semen, become more lustful and even gain physical features of an incubi. Like horns." he pointed to the horns which sprouted from his forehead and curved back "Skin." he pointed to his dark blue skin "Wings." a pair of wings spread from his back "Or a tail." an arrowheaded tail flicked upwards "For women one glass of Incubi Draft will have the same results." the Incubi grinned a fanged grin "That is to say they will become less feminine and more like a man. Their breasts will reduce in size and they will grow a penis themselves. Repeated consumption of Incubi Draft will magnify these changes until the woman in question will completely have changed into a man." the demon then gave a slight wistful sigh "But why would any woman want to do that? The body of a woman is more beautiful than any male body ever could be... with the exception of mine of course." Iratius laughed perversely.

"You are sick." Erza spat in anger and her blade flashed forward only to be stopped by the serrated blade of Vanitas

"Why thank you." the Incubus responded with a smile and downed the last bits of his drink "I am flattered." he then snapped his fingers and suddenly Erza buckled to her knees "As you can see my lust aura is quite strong, even among other Incubi." Iratius eyes flicked over to Naruto. Iratius snapped his fingers again and this time Vanitas surged forward and Naruto only narrowly avoided being sawed into two pieces by the hulking behemoth "And as long as your fine companion is occupied with my dear bodyguard you wont get any help, which is quite unfortunate for you. Because as long as you have that nice female body of yours you wont be able to escape my aura." Erza glared at Iratius with all the defiance she could scrounge up in her situation.

"Oh such a feisty look in your face." the Incubus smirked darkly "Are you one of those... what do they call them?" he seemed to be lost in thought for a while "Tsundere. That's the term. Are you one of those tsundere girls?"

Erza kept up her glare despite the continued assault of the demons aura "Damn you to hell."

"Hahahaha." the Incubus was definitely amused by Erza's attitude "I've been there it's not as fancy as people believe it is."

Sounds of stone being smashed and various types of magic being used could be heard throughout the building.

"Now, wouldn't you like to know why I haven't killed you yet?" a fanged grin spread across Iratius face "Building an army like that wasn't easy you know. Even if everything you killed was mere chump change. And keeping you alive has definitely nothing to do with me being an Incubus." Iratius elaborated "Quite simply my master desires your body as a vessel. Your magic power, for one as young as you, is simply extraordinary. If he can sap your magic instead of the magic of that cute shrine maiden..." Erza's eyes widned.

'Yayoi!' she thought desperately 'She has been captured by demon's all along?' But why had Erza not noticed anything? Why had the girl not said anything? If the scarlet haired girl could she would kick herself "then he is going to be at full power in a month at most. Then it wont even matter if there is no army to take over that quaint city, he'll just do it himself."

Erza racked her brain as she tried to come up with a plan to beat Iratius while Naruto spent his time dodging the serrated blade of Vanitas, desperate to overcome him.

He definitely didn't want to leave Erza alone with an Incubus of all things.

Vanguard demons are hulking juggernauts whose strength is almost unrivaled among demons. Their endurance magical damage is good enough to shrug of all but the strongest attacks and their resistance to physical attacks is only marginally less good. While they have no inherent magic power their physical power more than makes up for it.

With their strength ability to decimate most beings in a single blow they leave very little standing when they fight.

The only thing these demons live for is a good battle. There is next to nothing that brings them more joy and these demons will only listen to and accept those that can best them in a fight. To them your gender, race or age doesn't matter as long as you are strong. Which makes them somewhat of an oddity amongst demons as they have some semblance of a code of honor.

Should they be defeated by two people of different ideals they will follow the one that is stronger, that is, until one has defeated the other they will not listen to the commands of either.

Notable features: Lust Aura, Clawed appendages, Wings, Restores energy by feeding off sexual energy

Incubi are one of the most well known demons along with their sister species Succubi. They are lust demons that are reputed to visit humans during their dreams. They frequently engage in sexual intercourse with human females to drain them of their sexual energy which in turn restores their own energy.

As demons of lust they can freely create an aura of lust around them. The strength of this aura is determined by the strength of the demon and can range from a minor inconvenience to a debilitating force. However the aura of an Incubus will only ever affect females just like the aura of a Succubus will only ever affect males.

Incubi and Succubi are also well versed in the usage of illusions to further enhance the effects of their aura or to confuse a target in a fight.

While Incubi, just like Succubi, do not prefer hand to hand as they lack strength their claws and high agility, thanks to their wings, make them still a force to be reckoned with.
