DXD Issei trades devil wings for dragon wings

Chapter 1

This story is based on another story called Dragon wings by Susfi

Other than Issei giving his wings instead of arm to Ddraig and becoming a full dragon this will be different.

In this story Issei will sacrifice/trade his devil wings to Ddraig for more power while train for the Riser rating game. It will eventually result in Issei becoming a full dragon and having a dragon form plus devil powers, Issei's flames will eventually be very dark and a fire kind like the 'power of destruction' with red and black flames (more red than black). Issei's dragon form will initially be small for a dragon, no bigger than 1 - 2 time larger than the average human, he will grow larger and will be stated that he will grow even larger with time.

This will be a Rias x Issei story, it will defiantly be an Issei x Rias marriage eventually. If I'm any good I wright some sex scenes. IN this story there will be no such thing as a mate mark but Rias will become a little bit dragon after mating with Issei, so will anybody Issei might have sex with, if anybody.

I'm also extending the duration of the training camp to 1 month long so as to make it more realistic, you'll see how but Issei will be unable to participate in the rating game so I wanted the rest of the peerage to get enough training to make up for the loss of Issei and equal to same conclusion aka LOSS of the rating game so Issei will have to save her at the ceremony.

Issei training camp

Issei panted up the hill caring Satan knows what up a mountain in a ridiculously large back pack, at least ridiculous when not compared to everyone else's packs. Normal 100lbs would destroy any one foolish enough who tried to carry it up such a step and treacherous mountain, but Issei wasn't just anybody he was a devil. In fact so were the people he was with, Rias Gremory, the leader of their little group and the one to turn Issei into a devil, had organized this training camp to prepare the group, what the devils called a peerage, for their first rating game. Rating games were a substitute for devil clan wars. In the past when devils were more plentiful they would attack a rival clan or family in order to get what they want, anything from prestige to slaves but after the great war between the 3 Christian Factions the devil population was too low to risk the life of a devil for mere property. So along with the evil piece system, the way other beings are reincarnated into devils, the rating games were implemented. Issei didn't really know what the rules were but he didn't care all he wanted to do was butcher the ass hole who hurt HIS BUCHOU. Issei flair of passion and emotion gave him an incredible strength and he monetarily caught up with the rest of the group, but quickly fell behind again as Rias signaled for everyone to pick up the pace. Everyone either carried as much or more weight than him, even sweet little Asia, and while she was going at the same pace as Issei she neither stumbled or slowed down any more than he did, she only stayed with him out of pity. Asia was physically weaker than Issei but she had incredible magical potential and a sacred gear of healing that she had been using longer than Issei's balls had dropped, thus Asia's muscle had magic flowing thru them and it made them stronger and more efficient ever since she had be reincarnated.

By the time they had all reached the camp grounds Issei was wiped out his muscle were begging him to just die rather than live in such agony. Looking up Issei was awed by the 'family cabin' that they were staying at. It was a resort like mansion of stone pillars and glass that Issei would never call 'small'.

"Alright no resting, I've broken up everyone's training schedules into what I want you to focus on, we got only a month we can't waste it" Rias said handing out small packets to each of her peerage. Issei noted the slight sadness as she passed Issei, giving him a larger packet than everyone else.

'I'm fucking useless' he thought, 'she's counting on all of us', Issei knew what that look was about, he was the one who took up eight whole pawns, yet he couldn't even use a teleportation circle, he was nothing but a disappointment. Issei took a quick look at his training schedule, he had the most to make up for so it made since that he would have the most to do but this was ridiculous. The packet started out with stuff that even a human could do, sure it got progressively more intense and the magic training looked badass but the way Rias had talked about Riser's powers Issei knew it wasn't enough. 'I'm supposed to be her trump card, her amazing boosted gear wielder, a Longinus sacred gear that had the power to kill god. All this training can do is put me where I was supposed to be from the beginning'. Issei could see how desperate she was and his heart hurt seeing her like this. "don't worry Buchou this is all easy stuff I'm gonna start right away" he declared hoping to lift her spirits, he jumped straight up ignoring the pain and ran off to the area on the map designated for his 'strength training'. He didn't want to let her see his weakness so he waited to be out of even a devils eye sight and hearing before falling down and practically weeping in pain. Issei crawled the rest of the way to the small clearing.

Middle of that same night

After dinner and a males only soak in the supposedly enchanted healing hot spring Issei pretended to go to bed but he snuck out. Tomorrow was another strength day but this was led by Koneko and had a sparring match with Kiba in the afternoon for speed training. Rias had teased Issei saying that he'd need his sleep because Koneko wouldn't be very nice to her Pervy Sempai but it only made Issei feel even worse, those two would take time out of their more valuable training time to help a loser like him. Issei made it to his training clearing and began a similar work out to the one scheduled for day one. He didn't know the way up or down the mountain but he strapped a couple weighted plates to his back and ran I estimated equal distance, he hoped the running would make up for the lack of a steep angle. His body felt like light spears were inching slowly into his flesh but every time he began to slow down he imagined Rias being force to marry that douche Riser and his anger flared and he picked up the pace again.

Issei was less than a kilometer away from the finish line before his legs gave out and he fell, the plates on his back hitting his head as he fell to the ground. Issei was unconscious before he registered the pain.

(Mindscape)

Issei open his eyes to a Pale fog surrounding him. He attempted to feel for the bump on his head but he didn't even feel his arms. Looking down he saw no body. "shit did I die, is this heaven . . . . . wait devils don't go to heaven . . . . What's the afterlife for devils" he thought but in this place it was as if he spoke aloud.

"You are in neither boy, this is your own head" he heard from behind him.

Issei form swerved around and stared in shock at the source of the voice and was faced with a shaped mass of raw crimson energy. It look like some kind of upside down triangle with a tail coming out of the lowest point, it took Issei longer than he cared to admit that it wasn't really a triangle but a dragon like mass.

"The boosted gear? What was its name . . . . . . . red king something" het thought/said

"EMPEROR!!! RED EMPEROR DRAGON DDRAIG" the mass yelled, "you'll do well to remember the name, I am after all a part of you"

"RIGHT sorry Red Emperor-sama" Issei said doing a motion the felt like bowing even though he didn't actually have a waist to bend.

"F@@k those honorifics that's not how a real dragon talks" it said.

"Okay then how about . . . . (come on with something or look it up), after all you did help me out a lot when we rescued Asia" Issei said.

"It will suffice, you're not the first host to use that nick name, although you are the first to ask." Ddraig said 'strange he seems entirely genuine', "So why is it you're here" he asked.

"I don't really know, I didn't mean to come to. . . . . . You said my head?", Ddraig nodded conformation "I was training, trying to get stronger so I can stop holding everyone back" he said, his self-pity coming out in spades.

"So power is what you lust after, like every ho . . . " Ddraig was interrupted by Issei's passionate response

"HELL NO THE ONLY THING I LUST ATER IS BUCHOU'S OPP. . . I MEAN SEXY OPPAI" Issei yelled out passionately surprising the heavenly dragon.

"HA FAIR ENOUGH, so if it isn't power for power's sake than why do you want it" he asked.

"I have to, Buchou needs me, this asshole riser is goanna take her and marry her against her will. The only way to stop it is to win a match against him, and . . . and she wasted so many evil pieces on me but I'm weaker than if she only use one on someone else" Issei said beginning to tear up. "All I want is to make sure she's happy I don't care if I get my ass beat by riser, if I can weaken him enough for one of the other to defeat him then ill happy get beat!" he finish eyes still watery but the passion in his stare spoke volumes.

Ddraig was already aware of the situation but had learned, of the many hosts he had, to play his cards close to his chest. Ddraig had previous hosts who never learned to think for themselves always demanding an explanation or a solution like he was some sort of computer then claiming his title as if it they were the most important and unique one of an army of almost identical hosts. 'At least this one is different'

As he thought this Issei had continued his impassioned speech "like boobs like Buchou or those firm ass checks like Buchou or beautiful hair like Buchou's, huh I wonder if by love for the color red comes from you"

"What's wrong with liking red! It's much better than some shitty white, it just goes to show your quality as a dragon" Ddraig said. "And that sexy babe you got there isn't bad, she fine as hell heheheh get it! You should claim her as your mate"

"Whaaaaaa!!! No I can't I'm just a low class devil, she's pure blood Devil, even if she wanted me which she doesn't! I'm not even worth it as a onetime deal"

"F@@k that you're a dragon, A dragon does what he want to who he want when he want!"

"Wait? Why do you keep referring to me as a dragon? Aren't I a devil that's what Buchou did to save me, she reincarnated me into a devil" Issei asked, some instinct him told him this was important so he went from drooling pervy Issei to survival mode Issei, a mode he didn't really knew he had until he fought Raynare.

"That's a little complicated, Dragons don't really care about blood purity and all that crap, what matters to a dragon is your aura, which you'll get the stronger you get with the sacred gear. Your DNA will change to but only a little, honestly will your devil lifespan you might make it to quarter dragon blood but none of my hosts have ever been devils and no hosts survived sacrificing major body parts for more power which would extend their lifespans" Ddraig said.

"Why would I sacrifice a bod part" Issei asked.

"It's part or the Sacred Gear god imprisoned me into, I can take pieces or you and replace it with far superior dragon parts. A host can usually only survive it once but there was a time that it happened twice." Ddraig said.

"Would it mean that I could save Rias?" Issei asked

"It would give you an opportunity to, I can make no promises. Your opponent might not be much of a fighter but he has certainly more advantages then you." Ddraig said

"What will happen" Issei asked.

"Right now you are maybe 2-3% a dragon, your aura hasn't even changed that much. After sacrificing a part of your body you'll be anywhere from 15-25% a dragon and my energy will be flowing through you enabling me to add a limited portion of my raw power to you, this will enable me to artificially take you to the next level of your sacred gear called the balance breaker. It will hurt and probable mentally scare you but your body, magic, and instincts will be dragon-ish" Ddraig was enjoying the look of sincere awe on Issei's face, like a little hatchling hearing the elder dragon's war stories for the first time. "Your body will be stronger, your mind sharper, reflexes faster, your magic much more powerful, and you'll develop a natural ability for combat and fighting. This won't mean you'll be anywhere near Riser's level but it will give you a good boost and put you on a good path to far exceed the flaming chicken"

"That sounds perfect, what's the catch?" Issei asked knowing that something that sounds too good usually isn't.

"He! At least you ain't stupid hatchling" Ddraig said amused enough at his new host to refer to him in such an affectionate manner. "whichever part you give me will be mine for the rest of your life, you can control it but only if I let you. I've had hosts give me their hearts and get massive boosts but as soon as they stopped thinking about the beat of their hearts they died. The power you get is in proportional to the part I get."

Issei took his time thinking on this. If he gave something like a foot or hand he'd get power but there was no telling if it was going to be enough. If he gave his heart of lungs then he'd be more than strong enough to beat that arrogant bird but he'd have to actually think about that organ for the rest of his life. 'maybe there is a spell or technique I can use to not have to constantly beat my heart or use my lungs' Issei thought, but there was no promise that such a thing existed and then he'd be even more dead weight for Buchou. 'what about a whole limb or more than one like both his arms'. it was a good idea but Issei felt like it wasn't enough.

As Issei was thinking Ddraig was going over what this new host was like. 'this host was by far the weakest but it's almost like he doesn't have the anger and rage that humans typical have once exposed to the power of a dragon. I was exposing him to my power while here and even if it's a tiny amount it still should have affected the boy'. Humans were just not able to process or understand power like a dragons, even with his half-breed or artificially enhanced hosts, they all had been biological creatures trying to understand a power coming from beings energy. The original dragons were masses of raw energy that eventually formed together in to either gods or dragons. Like two side of the same coin, dragons and gods were essentially made from the same materials but that's where the similarity ended and a whole other story begins. So for a mortal, even devils can grow old even if it is thousands of years, being so natural while having Ddraig's power flowing around him should have brought that power starved red emperor host out, but for this weak little devil boy it was almost like the Ddraig's power hadn't affected him at all, at most it seemed to had made him willing to go even farther for his master. 'This boy will either accomplish great things or do terrible deeds, I can't wait to find out'

"Wings!" Issei said. "My devil wings, I can't use them to begin with so I won't have to do much more than I do now but the more powerful you are the more wings you have, at least for devils and angels. So Ddraig I give you my devil wings" Issei said. What he said was true, he wasn't able to fly and Buchou had given lectures to Issei and Asia about how the number of wings in the 3 factions meant how powerful the being was. But the real reason was that unlike his arms or legs he could hid his wings all the time so he could keep going to school with Buchou.

"Mmmmmm I am unsure if this will work, whatever those wings are they were created by the evil pieces used to resurrect you, it may cause problems for you." Ddraig said.

"Naahhh they are just like my arms and legs only I can hide them while in public and they are a little magical" Issei said. "Come on partner, I have to save her. I don't know why but seeing her dreams and desires violated like that makes me want to rip that assholes soul from his stupid immortal body and crush it in front of him." Issei finished.

While violent and unusual form Issei Ddraig loved it, this was the first real reaction that Ddraig's power had on the boy and it was a pure dragon reaction.

"HA VERY WELL HATCHLING ON YOUR HEAD BE IT, REPEAT AFTER ME . . . . . ."

Rias pov / 3rd person

Rias Gremory came down the stairs fully dressed and ready for the day. 'Like a true noble' she thought with disgust, any other day she'd take pride in her heritage but ever since Riser had shown up her thoughts had soured. She was and is still proud of being a Gremory but Riser had reminded her that she was seen as a Gremory and only a Gremory, never Rias. She'd been traded to a man that had practically raped her with his eyes then molested his queen if front of her. And Rias's own sister-in-law had done nothing. Rias had known that Grayfia would be unable to even aid Rias as a sister due to her brother being a Satan and legally no longer being a Gremory but as arrogant as Riser is he was a perfect politician. He wouldn't have shown anything other than a devoted innocent suitor in front of Grayfia unless he was more than just sure that she could do nothing. The only one to even try and defend her had been Issei, a conundrum hidden within a shell of a pervert.

Rias reached the kitchen/dining room to find her Queen and closest friend Himejima Akeno already starting on breakfast. It didn't take long for Asia to also come to aid the two in preparing a nutritious meal fit for training. Before they were down Rias heard movement and voices from the dining room and assumed her lovely peerage was awake and ready to kick some ass but when she peeked through the door to deliver the news of breakfast being almost done she didn't see Issei.

Issei was usually one to sleep in so when he wasn't up early helping make breakfast Rias didn't worry, But when her pawn still wasn't down by the time the table was set she knew she would have to punish her, admittedly comfortable to sleep on, pawn. Asia her adorable former holy maiden of a bishop volunteered to go and wake Issei up but Rias told her that it was a master's duty to punish her servants. Asia was many wonderfully sweet things but she saw Issei as a savior and a kinda pervy older brother so Rias doubted that she could adequately punish Issei.

Plus Rias wanted to see if she could get one of those adorably noble and pervy reactions, It was something unique to Issei that Rias had found utterly fascinating and just a little cute. Issei would try to move heaven and earth to see a girl naked but would rather cut off his own arm before touching a girl without permission. She had practically thrown herself at Issei, offering him her virginity but Issei had fought against her even though she knew he desired her body. Men had admired her body before, most times she hadn't cared but some had filled her with a sickening feeling like she was already raped and that was the nicest thing they were going to do to her. But she never felt that way with Issei, she couldn't explain it but she felt just at easy being completely naked in front of him as being fully dressed around her brother or parents.

Rias came up to his door prepared to wake him up in the most nose bleed worthy method possible but when she open the door the bed was empty, the bed still made and Issei's T-shirt and short that he usually slept in were still folded on the dresser. She checked the bathroom and shower to be sure but her pawn didn't seem to be here at all. Rias focused on the bond but all she could do was tell that he was somewhere to the west of her.

Rias went down to the dining room. "Issei's not here, I will go look for him, please eat then begin you training according to your schedules. Aneko please ensure no one slacks off." Rias said playing the calm and collected leader but on the inside she was nervous. She had seen how desperate Issei was in his training, and while he tried to hide it, she knew he was struggling. She hoped he hadn't done anything stupid

…………………………………………………………..

ISSEI

"Uuugggggghhhh fuck I hurt" issei said

"Fffffuuuuuccccckkkkkk" Issei felt pain in every fiber of his being as he picked himself up from the mud and grass

'Wait Mud. Grass. Ahh that's right I was in my mind' he thought 'I was talking to Ddraig. . . . . I think I made a deal . . . Yeah a deal I traded my devil wings to Ddraig for the power to save Rias' the pain was making his memory kind of foggy but he remembered repeating some kind of oath and then pain enveloped him and he blacked out . . . ' wait wasn't I already blacked out in the first place. How do you black out of a blackout????' He thought

'Fuck it I need to get back to the mansion, the sun is already up. I need to get back before'

"HYOUDOU ISSEI!" He heard and a shiver ran Straight down his spine

'Oh crap' he thought. Issei turn his head slowly and found a furious Rias flying directly at him

"Bu-bu-buchou!!!" Issei went into a flying kneel, head facedown back into the mud and hands splayed o the ground. It was his only hope.

Rias almost giggled seeing him beg but his dirty clothes and the dried blood in he's hair sobered her. "Issei what happened, have you been training all night. Look at you your hurt." She said getting close to Issei then moving his head like a bobble head trying to get a better look at the cut on his head.

"Ow buchou please stop that, that really hurts. I was just . . ."

'Hatchling keep quiet about what we just did, I'm not sure what all happened to your body but I do know it was a lot more than was supposed to happen' Ddraig thought to his host. "I need time to figure out what changed and what the damage is, for all I know sexy-red could hurt you by trying to take care of you'

'What the hell Ddraig, this deal was supposed to save her not kill me' issei responded.

'Relax it probably won't kill you' Ddraig said/thought

'Oh how reassuring' Issei mentally rolled his eyes.

'We just need to be sure. What ever happened I can already tell it more than any just my past deals'

"Muoooooo, Issei answer me!" Rias pouted.

"Sorry buchou I didn't mean to worry you. I was out training last night . . . This morning. I don't know But at some point my sacred gear talked to me and I sorta fell and hit my head" Issei bowed his head again "IM SO SORRY BUCHOU!"

"Uhhhhhhh you made me worry, come on you need to eat and Asia can heal you." she grabbed his arm and started to drag him back to the mansion.

"It's okay buchou, look see my head is already healed." he showed the cut and Rias could see that the swelling around the cut had gone down and the blood had scabbed and looked to already be flaking off. "Guess it must be my devil powers emerging hehehe. yeah so I can back to trai. . ." Issei was interrupted by his stomach loudly protesting it's lack of food. "GROWL". "Ummm I guess breakfast would help hehehehe."

Rias was dubious, Issei had never healed this fast and while devils did heal faster, Issei was freshly reincarnated. . . . "Oookkaaayyyy but You'll come to me if anything's wrong, I can heal you with skin-ship." She said moving her shirt collar just enough for him to get a good peek at her magnificent cleavage. "It's a master's duty to take care of her servants" she said, artfully blushing just the right amount to get a cute little nose bleed out of Issei.

"Fughhhh. Blood fountained out of issei's nose

'Mission accomplished' she thought as her fake blush turned into a very real one

Issei

Issei succeeded in dodging Everyone's questions and thanks to Claiming to still have a headache he was able to avoid training with Kiba and Koneko to do some 'light' knowledge training on his own. Issei was seated at the library's corner table with a book about devils in front of him but he wasn't reading it.

'Hey Ddraig are you in there'

'Yeah hatchling, I'm here What's up'

'What's up???? What's up is I wanna know what the hell is going on in my own body' issei yelled/thought to his live-in partner

"Hehe yeah I know I was just messing with you."

"Huff"

"Good news is that it isn't as bad as I feared." he said "your body has changed and is still changing faster than any of my previous hosts but it seems that either your devil side or your uniquely compatible body have saved you from changing out of control. Either way I'd estimate that your about a quarter (25%) dragon, this is as much as any of my hosts have ever been" Ddraig said

'That's great . . . Right?'

". . . ." Ddraig silence worried Issei

"Your devil wings seemed to be the core of your devil body, for some reason they didn't fully turn into dragon wings. Yes they look like and they have dragon energy flowing from them into your body. Right now they are about 90% dragon. the rest isn't really devil thou, it seems that the rest is a kind out devil dragon fusion, like some kind of hybrid' Ddraig said. "It also seems the devil energy that you did have before our deal has become hybrid energy too"

"Wow that's pretty cool, so I'm like a dragon that's been reincarnated?" Issei asked.

"No. Reincarnated dragons have both devil and dragon energies that are completely separate. Yours are fused, I don't know what this will mean for you. I'm sorry hatchling this wasn't part of the deal" Ddraig apologized.

"Does this mean I have gotten any stronger, can I not save Buchou!" Issei asked.

"Ha that's cute. I just told you you're a full quarter dragon! Like any dragon is weak." Ddraig laughed at his host

"Listen hatchling. Your far more powerful, probably more powerful than that fire chicken. Be carful because while your really strong you have almost no control. It's like trying you drain a pond with an eye dropper. You can try all day and not use even a single percent of your potential" Ddraig said. "if you want to beat him you'll have to train even harder than any hatchling I've ever seen"

Ddraig may have been trying to dissuade his host from arrogance but the only response he got was to cause Issei's determination to burn like an out of control wildfire

'I don't care what it takes I will save Buchou' Issei thought. Ddraig felt kinda foolish to believe this unique boy would be anything but what he called him, a hatchling, because even before their deal, Issei had been mentally already a bit dragon. And now he would only become more so

"One more thing hatchling" Ddraig interrupted Issei. "Your body is still changing, I don't know how much you'll end up being but all of this is unexplored territory for me too" he finished.
