Ok, so, first of all everything I know about DxD is from copious amounts of Fanficiton, as well as what I've read on the wiki. I've only watched the first episode of the anime and I've only ever seen the light novel in shops. Despite this I can say I love DxD, or at least I love the world it's set in and the concepts like Peerages, Sacred Gears and the like. The rest I'm not so big on. I actually enjoy OC fics that replace Issei. Not that I'm saying that there's nothing likeable about Issei, because there really is, but there's also a lot I don't like about him, as well as ecchi in general.

Basically what I'm saying is that this isn't any epic DxD piece where I'll be going into extensive thought and detail- this is just a way for me to write awesome shit happening in the style of the amazing One Punch Man, while also incorporating a few DxD fic ideas I've had.

This isn't really anything serious, and I just wrote it in my spare time for fun. I don't even know if I'll do more, but hey maybe I'll be talked into it. In any case, enjoy One Punch Devil.


Report from the office of Maou Sizrechs Lucifer-sama

"Across the country of Japan, various reports of Stray Devils being defeated before the peerage assigned to their destruction could get there have been made. The story is the same; when the King and their peerage arrives at the scene, the remains of the Stray Devil are found splattered all around the area. The one who kills the Stray Devils has yet to be seen, so information on his or her appearance, abilities, or alignment is non-existent. Nothing from the scenes of the fights indicates any type of demonic power has been used, nor light energy or even chakra. There are no marks to suggest what kind of weapon they use. The reports indicate that the one responsible for the deaths of the Strays is making their way across Japan. Their next location has been predicted to be the town of Kuoh."

Rias Gremory, heir of the Gremory clan of the 72 Pillars of the Underworld, frowned as she read the report for the fourth time. She had heard of the mysterious person killing Stray Devils, but she didn't realise the details were so sketchy. Without looking she picks up her cup of tea and takes a sip, starting from the beginning for the fifth time. The part that mentions demonic power, or lack thereof, interests her the most, and each time she read the report her eyes lingered on that bit a few seconds more than the rest.

'Nothing from the scenes of the fights indicates any type of demonic power has been used, nor light energy or even chakra.' With her inner voice Rias repeated the line, eyeing the words over her teacup. Her lips curled, eyes glimmering with intrigue. "Very promising."

"Buchou." The sound of her Queen's voiced brought Rias out of her musings. Akeno Himejima stood in the door way, a serious expression on her beautiful face. "We've got an order from the Archduke, there's a Stray Devil nearby."

"I see." Rias looked back to the report, her lips curling further. 'Hmm, perhaps we'll run into this mysterious Stray Devil slayer.' She stood up and gave her Queen a daring smile. "Get Koneko and Kiba and let's go."

"Yes Buchou."


With a quick teleport the group was in front of an old building, its decrepit look making it a perfect base for a Stray Devil. Rias closed her eyes and pushed her senses inside. Sure enough there was some Demonic power inside, indicating that the Stray was indeed inside. Her brief cursory examination complete, she signalled for them all to enter.

The Stray Devil in question was about as vile as the rest of their kind. His, if you could call it a male anymore, arms, shoulders, and head were still normal, but the rest of his body was bloated to a point where you could almost see his internal organs though his skin. His legs, once made of flesh, consisted of scales and spikes, and a large thick tail emerged from its lower back. Hands the size of tombstones dragged along the ground, razor sharp nails sparking against the stone floor. Rias frowned as she sensed the Stray's power; it was at least a Mid Class Devil when it transformed, and she knew that none bar herself and her Queen could take it on.

"Buchou, there's someone else here." Said Queen's voice brought the Crimson Princess out of her observations.

"What?" He gaze snapped to Akeno, who nodded back to where she had been looking prior. Looking back, Rias was surprised to see none other than a human standing in front of the Stray. It was no wonder the Stray was being so unresponsive to their entrance if it already had some prey in sight.

"Kekekekeke, you picked a bad time to go for a walk, human." The Stray pursed his lips in an obnoxious manner as he spoke, slurring his words like some sort of street punk. "See, folks like me get peckish this time of night, so we require a midnight snack." The human looked back at the Stray with a dull expression.

"Really? You know, I know this great Udon place nearby that does a special deal." The tone he spoke with stunned Rias a bit. Most humans would run screaming if such a monster even looked at them let alone speak to them. Yet this boy seemed almost…bored. "All you can eat for a thousand yen." The Stray gave a garbled chortle at his words.

"You're funny kid, but mere noodles aren't enough to fill the eternal hunger that wrangles my existence at every waking moment!" Rias rolled her eyes, grunts-

"Man, grunts always talk so weird." The boy muttered, scratching his cheek with his fingernail. The Strays amusement vanished.

"Grunt? You're calling me a GRUNT?" The Stray lashed his tail against the ground, cracking the stonework. "Do you know who I am what I've done? When my bitch of a King refused to put out for me despite all the signs she was interested, you know what I did? I RIPPED OFF HER HEAD AND SKULL FUCKED HER FACE!" Rias' lips twisted in disgust, angered by the monster before her ruining the reputation of Devils. "Would a grunt do that? Could a mere grunt kill a high class Devil so easily?!"

"Wow, you are pretty hard core." The teenager said, dead eyes sharpening in an instant. "I've heard some pretty messed up stuff in the last few weeks, but that's like the second worst thing I've ever heard." He pulled his other hand from the front pocket of his hoody to rub the back of his neck. "I didn't even want to know the apparently many uses of a giant high frequency vibrator."

"Enough talking!" The Stray had seemed to have enough with the banter. It threw its arms back and roared. His arms soon joined the rest of his body in expanding, going from twigs to steel girders in an instant. It grew taller, and his jaw dislocated and teeth grew sharper and longer. "Say your prayers boy because I'm going to show you the power of a true Devil! BLARGH!" Rias prepared to give her peerage the order to intervene, but the Stray moved blindingly fast for such a large beast, possibly suggesting he used to be a Knight piece. "DIE!" He weaved his fingers together and slammed his hands down, kicking up a large cloud of dust.

"Damn it! We were too late." Rias grimaced, staring at the dust, silently apologising to the human who'd just been squashed. The Stray's speed was worrying, it had moved so fast that Rias couldn't even react to its movements, it had killed the human before she could even open her mouth. "Kiba, take out its legs, we need to limit its movement. Koneko, once it's slowed down take out its arm-"

"Whew, that was a close one." Rias' words halted, and her mouth froze open as the dust cloud cleared, revealing that the human had dodged the attack by moving to the left slightly.

"Wh- HOW DID YOU DODGE MY ATTACK?!" The Stray roared, naturally baffled by the development.

"I moved." He said, as if it was the most obvious thing in the world and the Stray was an idiot for asking. The Stray clenched his teeth in an enraged snarl.

"DON'T GIVE ME THAT BULLSHIT!" It roared, spraying spittle at the boy, getting it in his dull grey hair. Then, against all odds, the Stray started getting bigger. "DON'T GET COCKY YOU BRAT! THIS ISN'T EVEN MY FINAL FORM!" The scales from the legs started to spread along its bulging stomach, and his spikes shot out from his shoulders. It grew by at least seven feet, and its tail took out half of the building with its thrashing. Its teeth grew down to its neck and up to its crown, where a large beetle-esc horn emerged. Rias took a step back in shock when its power leapt into high class Devil territory. "NOW YOU LITTLE FUCKER, IT'S TIME FOR YOU TO DIE! I'LL TEAR OUT YOUR DEAD EXISTENCELESS EYES AND GORGE ON THEIR GOOEY INSIDES! I'LL BEAT YOU FOR SO LONG THAT THE MOST TENDER OF VEIL WILL PALE IN COMPARISON TO THE MEAT I'LL DINE ON TONIGHT!" It threw up its arms, destroying the ceiling. The moon revealed the Stray in all of its hideous glory, and his beady, insane eyes bored down on the human teenager. "NOW DIEEEEEEE-URK!"

"What-" Rias started.

"The-" Kiba continued.

"Fuck?" Koneko finished.

Deeply implanted into the Strays bloated, armoured gut was the human's fist, contorting the scaly and near-opaque flesh. The Stray's eyes bulged and popped out its skull at the sheer pressure the explosion of force out of its back caused. Whatever remained of the building behind it was coated in blood and guts and gore, caused by the utter dismemberment the human's single punch caused. All that remained of the Stray was a red canvas and a foul smell. The boy remained in his pose, right arm full extended and his head bowed.

"…" He remained that way for a moment, before pulling back and staring at his hand, looking almost disappointed. "…Again…I ended it with one punch yet again." Silence reigned for a full minute before somebody finally said something about the situation.

"I am so fucking wet right now." And of course, it was Akeno. It was enough to snap the others from their funks, and they took one look at her blushing face and shuddered. Rias shook her head, long used to her Queen's preferences, and started walking towards the human, whose gaze lifted from his fist at the sound of footsteps.

"Huh, who are you guys?" He asked, but his expression indicated that he wasn't all that interested in hearing their response. Rias raised a brow, but spoke up anyway.

"It's considered polite to introduce yourself before asking others for their names." The human blinked, then rubbed the back of his head, scratching his grey hair.

"Fair enough I guess. I'm Kimura Takumi; I prefer Kimura."

"Well then, Kimura-san, my name is Rias Gremory." She glanced at the remains of the Stray Devil, which Kimura noticed. "We were here to take care of that but…well, you already took care of it." She looked into his eyes, her own curious. "From the looks of it, you're more than used to fighting their kind." He nodded.

"Yeah, those things are all so weak, I haven't had a decent fight in ages." Kimura sighed, shoving his hands into his hoody pockets, which Rias noticed has the word oppai written on the front. All things considered it was a nice hoody. "I'm just too damn strong."

'Hmm, he seems to be the type who enjoys a good fight. Essentially, a battle freak.' Rias considered him for a moment, weighing her options, and smiled a smile that could only be described as…devilish. "Tell me, Kimura-san, how would you feel about fighting an immortal?" And for the first time that night, the grey-haired teenager looked slightly interested.

"An immortal…you say?" His lip twitched at the corner, tugging up into a little, lopsided smirk. "Do tell me more."


"Allow me to fill you in on my offer, Kimura-san." They had returned to the old school building to discuss the finer points of what Rias was offering to the human. It was just him, her and Akeno left, with Kiba and Koneko having gone back to their homes to turn in. Kimura gazed around the room, looking impressed by the grandeur of it all. His attention was dragged to Akeno, who had leant over him to pour him a cup of tea.

"Ah, thank you." Akeno gave him a wink, her cheeks still a little flushed from his early performance.

"Ara, I should be thanking you for the amazing show of dominance you gave back with that Stray. It got me rather hot."

"Eh?" Kimura blinked, his eyes oval shaped and his mouth open a little. "S-Sure." He took a sip of the tea as she gave a short 'ufufu' of amusement. 'Man this chick is crazy. Hell of a rack though.' "Huh, this is pretty good." He took another, longer sip, and then held the empty cup up. "Could I have seconds?"

"Of course, I'm glad you like it." With another wink Akeno poured him another cup.

"Ahem, anyway, as I was saying." Rias interrupted, trying to get the conversation back on track. Acknowledging her King's unspoken demand, Akeno stepped back and folded her hands across her stomach. Kimura for the first time since he sat down, gave Rias his full attention, although his disinterested look irked her a little.

"Yeah, you said something about an immortal earlier, what was that about?"

"Well, before I get into that allow me to give a little background information on what we are." Folding one arm under her chest, she rested her elbow on her palm and held a finger up, poised and ready to give a lecture. "Let me get to the point and tell you that we are Devils."

'That's it? That was quick.' Kimura was relieved, if there was one thing he hated it was long winded explana-

"For thousands of years ago there has been the Three Factions who are connected to one another, us the Devils, the Angels, and the Fallen Angels. Together these three factions were the basis and inspiration for the Judeo-Christian religion, and they became a part of the Bible." Kimura's eyebrow twitched, but Rias continued regardless. "These three factions warred against each other under the leadership of the Four Great Satans for the Devils, the Biblical God for the Angels, and the Grigori organisation led by Azazel for the Fallen Angels. For millennia we have been in a state of cold war, where there are no outright hostilities but another war could break out at any point." Kimura's brow twitched more, and his left leg began to bounce up and down. "Due to the war the population of the Devils took a large hit, and natural birth among Devil families is rare. To deal with this issue one of the four Great Satans created the Evil Piece system, a system similar to the Human game of Chess. Through this system High Class Devils such as myself can change another species into a Devil servant under their command. These servants, otherwise known as a Devil's peerage, can be used to wage a competition known as Rating Ga-"

"GOD DAMN IT!" Rias and Akeno winced in unison at the use of the Lord's name, while at the same time looking at Kimura in shock, who had accompanied his yell by slamming his hands onto the table. Fortunately the expensive antique table took no damage. "YOU SPEAK WAY TOO MUCH! SUMMARISE YOUR POINT IN 20 WORDS OR LESS DAMN IT!" His face had discarded the bored and disinterested expression it usually held to adopt one of intense seriousness.

Rias continued to gape, flummoxed by the sheer gall this human has to interrupt her. Akeno was the first to snap out of her surprise, and she covered her mouth to hold the intense laughter building up inside at her King's face. Finally she stammered out a response.

"Y-Yes, well…" She struggled in her brain to try and compress all the information she wanted to purvey into such a limited word count. "B-Basically, I need strong allies so I want to make you a Devil as my servant to help me."

"See, isn't that much better. Nice and concise." Kimura gave the stunned red-head a lazy smile as he took a sip of his tea. Akeno finally couldn't take it anymore and started laughing loud and deep at the look on Rias' face. Akeno took a deep breath, trying to hold back her chortling. Her laughter threatened to renew itself at the glare on Rias' face but she managed to collect herself. Kimura took another sip, draining the cup, and carefully put it down on the table. "So in short, you want me to become your servant because you want to beat somebody super strong in the future, am I right?" Rias gave him a baleful look before answering.

"Yes, that is correct." She frowned as she took in his reaction. "I must say you're handling the existence of Devils, Angels and Fallen Angels rather well." Kimura shrugged.

"Yeah well I've been fighting those things for weeks now, so the fact that there's more supernatural stuff out there isn't really a surprise. What's the deal with those things anyway, and keep it snappy I don't want to sit through another long drawn out explanation." Rias' eye twitched, her irritation growing, but she held her tongue knowing that he could probably splatter her against the back wall if he wanted to.

"They are Stray Devils. As the name suggests, they are Devil servants who have gone stray by killing their masters, and the Evil Pieces inside of them went wild without their master and mutated their bodies to monstrous proportions."

"Also, what exactly are those Evil Pieces?"

"They allow High Class Devils like myself to turn other species into Devil servants."

"Right, so you'd use one of those to make me a Devil?"

"Yes."

"And becoming your servant will let me fight someone who's immortal someday."

"It is highly possible, yes." Rias looked down, her eyes losing focus somewhat. He grip on her teacup temporarily tightened, then relaxed. She looked back up, gaze turning determined once more. "That isn't the only thing you would get from becoming my servant. Not only would you get even stronger upon becoming a Devil, but you will one day be able to have a peerage of your own and participate in Rating Games yourself, where there are many strong opponents. You could even form a harem if you so desire, it is not an uncommon practice in the Underworld."

"Huh." Kimura looked up in thought, mulling it over a bit. 'Strong opponents, a chance to fight an immortal, a harem? Sounds almost too good to be true.' He thought about the last bit some more. 'I suppose a harem would be cool, but then again it might be a bit high maintenance. More importantly, am I really prepared to give up my humanity so easily?'

"There are other benefits from being a Devil." Rias pushed onward, almost sounding desperate by this point. "Devils live much longer than humans ever could. Devils can live for thousands upon thousands of years."

'Thousands of years, huh.' Kimura threw his arms around the back of the antique sofa he sat on and leant his head back, looking up at the ceiling. 'That's a long time…' He closed his eyes, weighing the pros and cons in his mind. Rias had run out of things to convince him with, so she just watched him in silence. Akeno looked on, hopeful that he'd say yes for Rias' sake if anything. Silence reigned for several minutes, and Rias was growing anxious.

"Kimura-san, you don't have to decide right now. You can sleep on it if you want." He didn't answer, and after a couple of minutes Akeno got curious and walked over. Taking a look at his face, she smiled.

"Ara, it seems he already is, Buchou."

"What?" Rias shot out of her chair and stormed around her desk and over to Kimura, who lo and behold was in fact asleep, a giant snot bubble coming from his nose. Rias saw red. Here she was, desperately trying to have this guy join her peerage, putting her pride aside in the process, and he was napping? "WAKE UP!"

"WAH!" He shot up, snot bubble popping. He stared at Rias, wide tired eyes gazing into fierce blue. "Er, sorry about that." He scratched his head nervously as Rias smouldered. With a huff she marched back to her desk and sat down, crossing her arms and closing her eyes.

"I would appreciate an answer now, Kimura-san. If you don't wish to become a Devil, then please leave at once."

"Alright then, sign me up."

"Very well, the door is over th- wait what?" Her eyes snapped open and she stared at him, arms slowly loosening. Kimura smiled, resuming his previous position, this time looking Rias dead in the eyes.

"I said I'll become your servant, being a Devil might not be so bad. It might liven up my boring life a bit. And besides, if it means I get to drink that delicious tea everyday it'll be worth it."

"Ara, I think that can be arranged." Akeno said with a closed eyed smile. Rias stared for another moment, before smiling in triumph and standing back up.

"Very well, Kimura-san, if you'll just lie down for a moment, I'll turn you into a Devil right away." Kimura grinned back.

"No time like the present, any time afterwards is the wrong time." He got slid off the sofa and lay down on the floor as Rias came to stand over him. A red magic seal appeared underneath him, and Rias placed a pawn piece on him, reconsidered it for a moment, and then put seven more on.

"I, Rias Gremory, hereby order you; Heed me, Takumi Kimura. You shall become my Pawn and rejoice in your newfound life." The eight Pawn pieces sank into his chest, which began to spark red lightning. The Pawn pieces were then pushed back out, and before Rias could express her disappointment, all eight of them began to change. "Mutation pieces?" Rias gasped, yet again stunned by the events of the night. The eight Mutation Pawn pieces then sank back down into his body, this time readily accepted. The magic circle faded away, and Kimura blinked.

"Is that it?" He wondered, sitting up and looking down at his hands. "Hmm, I guess I feel stronger." He then blinked and looked out the window. "Huh…it's a lot brighter out there than I remember." Rias and Akeno just blinked at him owlishly.

"Yes…that would be your new Devil vision." Rias decided to just roll with it. If she didn't hurry up and get used to the nonsense that occurred around him, she'd never stopped being surprised.

"So, what now?"


Indeed, what now? I may or may not write more. But, little insight, I do have an idea for a little something for Kimura to deal with.

Next time (maybe) on One Punch Devil- The Stray Devil Faction.
