Disclaimer: I do not own High School DxD. I only own the OC Damian Mammon-Lucifer.

'So, this is Kuoh Academy huh.' Damian Mammon-Lucifer thought to himself as he stood before the gates of the former all-girls educational school in the human world, in the town of Kuoh, Japan. He really didn't want to be here, but his mother had convinced him to go for the simplest reason that it's where his future wife, Rias Gremory, goes and it's time the two meet and start spending time together before their eventual wedding.

It didn't help that he had his father, as well as Rias' own parents Zeoticus and Venelana supporting the idea and telling him to go.

'Compared to schools in the Underworld, human ones are going to be so boring.' Damian thought with a sigh before he made his way towards the gates, seeing that the school day hadn't begun as many students were still arriving or hanging around the campus. He took note that there was more girls than boys, which is understandable given it had been an all-girls school, and only turned co-ed recently. Most guys Damian's age would be over the moon to be surrounded by so many girls as attractive as the ones that Peter has seen so far, but most guys didn't have the fortune or misfortune, depending on who you asked, of attending one of if not the most prestigious school in the Underworld that was filled with various Succubi… human women seemed kinda stale in comparison after a semester there surrounded by lustful demons that could arouse or bring any man or woman to orgasm with dirty talk alone.

'Though I won't lie… there are a few very attractive girls here.' Damian thought as he looked over a couple of girls nearby, how their uniform fit snuggly against their curvy figures and showed off their breasts. And don;t even get him started on the skirt, which was about as short as the ones Moka usually wears that nearly flashes her ass with just a slight breeze.

The girls' uniform consists of a white long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, a black shoulder cape and matching button-down corset, and a magenta skirt with white accents.

The boys' uniform, which Damian unfortunately had to wear,consists of a black blazer with white accents over a white, long-sleeved, button-down shirt with vertical linings, a black ribbon on the collar, matching black pants, and brown dress shoes. However, Damian chose to toss the dress shoes aside and wear a simple pair of black trainers.

He didn't make it ten steps past the gate when two girls blocked his path, making him raise an eyebrow. They were fairly attractive, with one having golden eyes and long brown hair. She wears bangs with long strands hanging down to the left and right of her face. The other girl beside her had pink hair and wore a white headband.

"Yes?" Damiana sked, raising an eyebrow.

The girls blushed before the girl with brown hair spoke first. "Um, hi... are... are you new here?"

"Yes." Damian said blankly, staring at the girl.

This time it was the other girl that spoke. "Would you like a tour of the school? Me and Murayama here can give you a look around"

Damian frowned at this "Why?"

"It's a big school." The one that Damian figured was Murayama said with a blush "It's easy to get lost if you're not familiar with the layout. Katase and I did on our first day."

Katase nodded. "Yeah, we were almost late for class and miss Nii hates it when your late."

"Well, I." Damian stopped talking when eh heard multiple students gasping as they saw two people pass the school gates together/

Katase and Muryama looked over and gasped. "What is happening here? Is he supposed to be cool now?" Muryama asked in horror as she clutched Katase's hands.

"Yes! And I think it's working!" Katase exclaimed as if all hope had vanished in the world. Damian raised an eyebrow at their dramatics before following their gaze to see what the big deal was and who they were talking about, only to see an attractive red head dressed in the academy uniform followed by a guy around Damian's age, maybe a little younger. But Damian's attention was focused solely on the red head… Rias Gremory.

'So, that's her, huh.' Damian thought as he stared at the heir to the Gremory clan and his apparent future wife.

She was a beautiful young woman with white skin, blue eyes and had a rather… buxom figure. The most distinctive feature about her aside from her gifted chest was her long crimson hair that reached down to her thighs with a single strand sticking out at the top. She was clad in the same uniform that all girls at the Academy wore with the only addition to the outfit being a shoulder cape she had on.

Rias seemed to sense Damian's eyes on her as she suddenly turned her gaze right at him. Her eyes narrowed slightly in confusion before they widened ever so slightly as a look of recognition rushed through them. Even though the two had never met in person, they've seen enough pictures and descriptions of the other to get a clear idea of what the other looked like. It also helped that Rias could sense the powerful Demonic energy and magical power emanating off of Damian.

Damian and Rias held each other's gaze before it was broken when Rias and her follower entered the school.

Murayama and Katase were still complaining about Rias walking to school with the other boy, but after a few minutes turned their attention to the attractive young man before them.

"So... about that tour?" Muryama asked with a small, hopeful grin that was mirrored by Katase.

Before he could give an answer, he suddenly began to smell the ever so subtle hint of lust from the two, and it seemed to be directed towards him. At this, Damian sighed as he looked towards the two girls with an uninterested expression. "Look I appreciate that you two think I'm good looking enough to engage in what appears to be a premarital threesome in some secluded place rather than attend the first two or even three periods of school, which by the way is a bad idea because there are so many ways that can come back to bite you, but I'd rather get to class and get this day over with."

"Aww." The girls' whined and pouted, causing Damian to nearly roll his eyes at these humans and their hormones. Even a Succubus could be in more control than them... and he would know from experience and interactions with Succubi.

"Look, get back to me next week and I may have reconsidered it, alright?" He said, which brightened them up as they nodded. Nodding back, Damian passed them. "See you around... not." He muttered that last part as he went on his way towards the building.

He had just entered in time to hear that boy, whose name he heard was Issei from the constant chatter of gossiping students, was bragging to two of his friends about how he got to see Rias naked.

Damian pinched the bridge of his nose. 'I'm starting to regret this... and now I owe Irene, Moka and Kuroka money.'

Rias walked up the stairs to her class, with much on her mind. However, someone's amused voice brought her out of her private musings.

"You seem very certain about him." Said a young bespectacled woman with a slim figure, black hair styled in a short bob cut and violet eyes. She gave Rias a grin as the red head glanced at her in slight surprise. "Hello again Rias. Good to see you."

Rias smiled and walked over. "It's good to see you, Sona." She walked over the railing and leaned on them.

Sona Sitri was Rias' childhood friend and rival. She was the third most popular girl at the academy, behind Rias herself and her Queen, Akeno. She was the current president of the Student Council that also happened to be made up of her Peerage and happened to be one of if not the smartest student at Kuoh Academy. Something she was both proud and annoyed of. Sona often complained there wasn't enough people here to offer her an intellectual challenge.

"Never seen you take on anyone so impulsively," Sona commented. "What makes this one so special?"

Rias gained a thoughtful expression on her face as she stared down at her newest Pawn. "I don't know exactly…" Her look then turned towards a grin. "Though I will say it feels as though I adopted a little brother."

"I see…" Sona said before her attention shifted towards a boy that gave the three a dry look before he turned on his heel and began to make his way to his first class of the day. Her eyes narrowed as even from where she was, she could feel the dark and powerful energy rolling off of him. "So that's him… the one your betrothed to? Damian, was it?"

Rias followed her friend's gaze and saw Damian just as he moved beyond her sight. She nodded slowly. "Yes… that's him. The grandson of the original Lucifer himself…"

"Hmmm…" Sona sounded as she pushed herself off the column. "Well I will say this, he's definitely living up to his family's reputation of seemingly unrivaled raw power. I've never met a Devil from any Clan his age with so much power, even ours. He could level the entire city on his own if given the chance. At this rate, he'll trump even your brother before we graduate."

"Yeah… I'm sure he will." Rias said as the bell rung. She looked towards her friend and gave her a smile. "See you later Sona…""

"Same." Sona responded with a small smile.

The bell for the end of school finally rang.

"Finally." Damian muttered to himself as he grabbed his bag and got out of his seat. The day had been so utterly boring, since all these classes were about subjects he learned at a younger age. His mother had seen fit to not only have him educated in Devil society, given he'll need to make appearances and attend events because he was not only the grandson of the First Angel and First Devil himself, but because he was the heir to the houses of Lucifer and Mammon, but she also made sure he was well educated in stuff from the human world, history, maths, you name it, he was taught it growing up.

Lunch had also been pretty bland, as the Devil had stayed far away from anyone else to have his lunch quietly. That did not stop girls from 'whispering' about him and sending him certain looks. Having superior hearing like his, their whispers were futile. If only they knew that he could hear the things they were saying about him...

Now that school was over, the grandson of Lucifer wondered what to do next. Perhaps go and finally meet Rias, or save that until she requests a meeting with him and go to see if his residence was up and running.

He had to decide on the first one given the fact Rias herself stood in the doorway of the classroom, looking at him.

"Damian... Mammon?" She checked, as Damian had taken 'Lucifer' out of his name when put in the school register.

"Yes?" Damian asked with a nod and a quirked brow.

"Can we talk?" Rias asked, leaning against the doorway.

Damian gave a single nod and moved out of the classroom, while being glared at by several jealous guys, and even some jealous girls who swung that way, while Rias was glared at the most by the rest of the girls in the class. There was also looks of lust thrown at him and Rias from the girls and boys respectively.

'If there was ever an embodiment of the sin of lust... the students of this school could probably worship it.' Damian thought dryly, shaking his head as he walked beside Rias.

"Enjoy your first day?" She asked him with a smile.

"It was mediocre at best." Damian answered with a shrug. "I suppose the only entertaining thing about it would be the other students. Half the girls wanted to take me somewhere private to have sex, while the guys seemed to go into some primitive alpha caveman mode."

"Don't look too much into it, trust me your time here will be far less complicated. Just smile and nod, maybe give the polite word or two before kindly letting them down or finding a way to get away from them." Rias advised as the two wandered down the hallway.

Damian sent her a look. "It cannot be that easy, especially with humans."

"Humans are so easy, and it's how I get by the constant attention." Rias said, before smiling and waving at a group of guys that they passed. "Though... unless you're attacked, and only fight back in self-defence, try to go as easy on them as any other human would. If you killed someone on accident, it'll get the attention of the Church and possibly the Fallen Angels."

"Like I'm scared of those cross-wielding fanatics who think they are tough because they listen to God Himself." Damian said with an eyeroll. "And as for the Fallen Angels, those pigeons don't intimidate me. They'd have better luck trying to get back into Heaven than making me afraid of them."

They continued like this, making idle conversation, as they exited the main school building and went in the direction of an old-looking one that was clearly not used much given the sight of the vines creeping up to the second story. Rias explained that it used to be a used building, but soon was left abandoned and Rias took it up as her base of operations for her and her Peerage.

Walking up some stairs and approaching a set of doors, Damian giving a brief glance down the hallwat where he could see a closed off door that eminated an aura of power, Rias pushed the doors open and stepped in, turning around to smile at him while gesturing to the clubroom.

"Welcome to the Occult Research Club." She introduced.

The club room interior is a wood-paneled room with Victorian-style couches and chairs along the walls. One side is set up to be able to be used as a bath, and a large Gremory Family magic circle is also there, no doubt to allow teleportation to and from clients.

So, this is where you and your group hang out." Damian stated as he checked the room. "Not bad, I must say, for a club."

"And you can do better?" Rias challenged with a grin, crossing her arms underneath her bust.

Damian shot her a smirk. "Don't tempt me. But no, my Peerage and I are fine with what we've established as a permanent HQ. We run a bar called Seventh Heaven, which used to be a small establishment but thanks to my family's funding and much customer satisfaction... it's become bigger than what it used to be. Before I came here, I had the penthouse in the town bought and owned by me, as well as redecorated given it has a nightclub at the lobby so that helps."

"Living the high life, huh?" Rias giggled, sitting down on one of the couches and crossing her legs at the knee. Damian took a seat across from her, eyes looking at the chess board left unattended in the midst of a game.

"I'm a Devil." Was all he said in response to that before he narrowed his eyes in thought. "So... how will this work between us? Neither of our families are pushing for the marriage to happen early, and we ourselves haven't decided when to have the date arranged."

"To be perfectly honest, I thought I wouldn't meet you until after I was done with school and going into college." Rias admitted. "I had heard you travelled the human world while searching for Peerage members, but nothing more, not even if I'd meet you earlier than expected."

"I've been a busy guy." Damian shrugged.

Rias was silent for a couple of minutes before she finally spoke. "Do you want to wait until we've finished school?Granted it'll be a few years but for people like us it might as well be a few hours."

Damian didn't get a chance to respond as suddenly the door opened and another person entered the room. Both Damian and Rias turned to see who had interrupted them, causing the newcomer to blush and chuckle sheepishly.

"Sorry… am I interrupting something?" She asked.

Her name was Akeno Himejima and like Rias she had a voluptuous figure but whereas Rias' hair was scarlet in color, Akeno's was black and even longer, reaching down to her legs even in a long pony tail with two strands sticking out from the top and sloping backward and an orange ribbon keeping it in place. She was clad in the Academy uniform for girls, like Rias along with a pair of black calf length socks.

Before Damian could speak, Rias cleared her throat as she gestured towards him. "Akeno, this is Damian Mammon-Lucifer, the one that I told you about in regards to that arrangement that my family and his made several years ago."

Akeno's eyes widened at this. "Oh…" She then turned towards Damian and gave him a kind smile and a bow. "Welcome to the human world. Japan specifically. I hope it's been a grand experience for you."

"Compared to other places in the human world that I've been to? It's alright." Damian shrugged. "So, what is it you do here? Do you actually study the occult? We're meant to have learned all of that in preschool."

"No, we do actually study the Occult, for appearances sake of course. But it's manly a cover to hide our real activities" Rias revealed with a chuckle "I'll explain it better when I gather the rest of my Peerage to meet my newest Pawn"

Damian nodded at that as he settled into the couch while Akeno came to sit next to him and crossed her legs as she took in his appearance. She liked what she saw and sensed.

"So, Damian, do you have your own Peerage?" she asked.

"A Queen, two Knights, Two Rooks, and Two Bishops." Damian said, then glanced at Rias as she stood. "I take it you'd know one of my Bishops, given it wasn't exactly quiet with the situation."

"You mean finding out Kuroka was innocent and has reason to kill her master?" Rias asked with a raised brow. "Yes, I know of it. The whole Underworld knows of it, Damian. Kuroka killed her master to protect her little sister, who is also my Rook, because he had been experimenting, trying to create his own Super Devil through illegal means that would've given him the death sentence had the Satans put him on trial."

Damian nodded, glad she had heard. Not many had seen fit to forget Kuroka's crime in killing her master, regardless of the reason... and it just so happened to be several purebloods who were way too into the old ways of Devilkind, like the Elders. "Good. You know we'll have to have her and her sister meet at some point."

Rias nodded silently, saying nothing. Instead, she began to strip in front of her future husband and Akeno. Damian blinked in surprise, watching her, unable to tear his eyes away.

Akeno giggled and leaned on him. "Enjoying the view? Taking in the image of your future wife naked? Planning where to eventually put your hands, tongue, and 'other' parts of you?"

Damian shot her a dry look. "She's the one who decided to strip."

Akeno giggled again as she leaned into him and whispered into his ear. "You wanna join her in the shower? It'll be a while until the rest of her Peerage show up and you look a little tense, perhaps she can help relive that tension…" Her eyes glanced down to Damian's pants and she grinned at seeing a noticeable bulge. "Among other things she could help you with."

rias giggled in amusement as she glanced at them. "Akeno, leave him alone. If he wants to join me... he's more than allowed of his own free will."

Damian blinked at this and looked at her. "Really?" He asked, surprised she was willing to go that far with him this early, they had just met and barely know each other.

"Damian, you and I are gonna be married in a few years and there's no doubt that your family has been hinting that they'd want a child born of our union as soon as possible once that happens like mine has." Rias said as she removed her underwear before stepping into the shower and turning on the water. "Might as well get used to the idea of having sex with one another."

"As... lovely as that idea would be, and I'm sure others would jump at such an oppertunoty, I'm not that kind of guy. I'd rather court you and get to know you before jumping into bed with you. Call me classy, but my mother raised me to be a gentleman. So, I'll take you out to dinner first before we start to have thoughts of sex." Damian said.

"…That'd be nice." Rias said with a small smile as she pulled the shower curtain closed.

Akeno grinned at this as she rested her chin on Damian's shoulder. "Aww what a gentleman. Buying a girl dinner first before sleeping with her."

"Like I said, my parents raised me right." Damian reminded. "I am a Devil, and have had my fair share of... experience in the sexual department, we are creatures of sin like lust after all, but I'm not some horndog who'll jump at the chance to sleep with a girl because she showed a ton of skin to me. Can't say the same for other Devils who think with their dicks rather than their brains, like that Riser Phenex."

An annoyed groan came from the shower. "Don't even get me started on him. Growing up, I'd find him at several events and galas, and he'd whine and complain about how my father cancelled the intended arrangement between me and him to you and me."

Damian snorted. "He does realize the deal was made before either of us were born, right?"

"I don't think he cares." Rias said dryly. "To him, all he knows is he can't marry the Gremopry heiress. A good thing too, the things he's said, and his gaze... he even stared at my mother like a piece of meat!"

"Yeah, I know what that's like." Damian said darkly. Riser had done the same thing when he attended a party at Lucifer Castle, staring at any attractive women like a hungry wolf, and even trying to seduce several of them into bed with him. He didn't even spare Damian's mother or her Queen from his lustful gaze, and Damian very nearly tore his eyes out for it had his mother not calmly kept him from doing such an action.

The sound of the door opening caught their attention, and they looked to see a young-looking girl entered the room. Akeno gave the newcomer a small wave "Oh hello Koneko. Surprised to see you here so quickly."

Koneko was a rather short petite girl with white hair with a cat head shaped clip on each side of her hair. She was dressed similar to Rias and Akeno but minus the shoulder cape.

Koneko simply shrugged before she glanced towards Damian. "Who's he?"

"This…" Akeno said as she wrapped her arm around Damian and pulled herself against his solid build. "Is Rias' future husband. He's the one who helped clear your sister's name. Isn't he cute?"

Koneko stared at Damian, who could see multiple emotions weighing in her eyes. However, she was still indifferent as she shrugged. "I guess."

She then went and sat on the couch parallel to Damian and Akeno's and began to help herself to some of the treats that were laid out.

"You don't talk much, do you?" Damian asked rhetroically.

"No." Koneko said in a deadpanned tone as she and Damian stared at each other with blank expressions on their faces.

Several minutes of silence passed with the only sounds being Rias in the shower and Akeno excusing herself for a few minutes as she remembered she had to go take care of something for Rias. It was then that the door opened, and Damian turned to see two guys enter this time, one he recognized as Issei, the other not so much.

Damian's eyes narrowed as he sensed something off about the other man, something almost… Holy.

'Now that's interesting.' Damian thought as he watched Issei look around the room with a confused expression on his face.

"What's happening, where are we?" He asked with a frown before he noticed Koneko sitting on the couch eating one of the treats laid out. "Wait, I think I know her"

Kiba glanced at Issei in response with a quirked brow. "Oh? Koneko Toujou's a first year and a valued member of the Occult Research Club." Said girl looked up upon hearing her name. Kiba gestured to Issei. "My friend, Issei here, thinks he might know you."

"Uh... I-I could be wrong." Issei said nervously.

Koneko simply nodded in greeting before going back to her cake, Issei looked down at the plate on the table and noticed the small cake there was half eaten. Issei looked away from the plate as he started to hear the sound of water towards see a curtain to what appeared to be a shower, and beyond the curtain he could barely see the fuzzy silhouette of Rias' naked body in the shower room.

"Your clothes are laid out for you when your ready, Ms. President." Akeno said as she stood back with a small grin on her face, having quietly slipped by Issei and Kiba.

"Thank you, Akeno." Rias said from the shower before the water had been cut off.

"I just heard Rias taking a shower, I love this club!" Issei said with far too much excitement than Damian was comfortable with.

"Man, you really need to get yourself a girlfriend kid… or a very much needed kick in the ass." Damian said with an eye roll, drawing Issei's attention to him.

"W-What, who are you?" he asked with a frown, having never seen Damian around the school before.

"Wouldn't you like to know?" Damian retorted.

"I would!" Issei's eye twitched.

"Sorry for the wait." Rias' voice said as she stepped out of the shower, dressed in her school uniform and drying her hair with a towel."I know it's terribly rude, but I didn't have a chance to wash after leaving your place."

At this, Damian's interest was piqued. "Excuse me?"

Rias looked towards Damian and gave him a sheepish smile. "It's not what you think.

"You'd be surprised by what I can think of…" Damian said as he turned towards Issei with a frown who in turn gave Damian an embarrassed grin.

Damian gave the man a dismissive grunt as Akeno sat on one side of him and Kiba on the other, though with a small space between both of them, while Issei sat down next to Koneko who kept one eye on him as she ate her chocolate treat.

"Well now that everyone is here, I'd like to officially welcome you into the Occult Research club." Rias said with a happy expression towards her newest Pawn.

"Uh... thanks." Issei said with a nod.

"But you should know that the name of the club is just a front. It's supposed to look like some kind of hobby" Rias said, her expression becoming more serious but still light-hearted enough.

"Okay, what is it really?" Issei asked.

"Well, since you asked I'll be frank with you; I'm not the only Devil here, Issei." Rias told him, shocking Issei as he looked around at everyone else.

"Wait, you're saying everyone here is a Devil?" Issei asked.

"Yes, and the winged man from yesterday was something else… a Fallen Angel." Rias said. "Some think we're the same which isn't true. They want to serve God but it's too late for them. Their dark emotions have forced them into the Underworld. The confusion is understandable because they too walk the earth misguiding humans, but they wish to please God so their goal is to wipe us Devils out and gain supremacy over our realm. You call it Hell. And of course, there's the more recognisable Angels who are clearly sent down by God to defeat us as well. So we're constantly defending ourselves from both Angels and Fallen Angels."

"Uh..." Issei trailed off, looking unsure of what to think and being quite overwhelmed from learning that creatures that were meant to be myths were actually real.

Rias noticed his expression and asked. "Something wrong? You look a little overwhelmed."

Issei blushed a little at this as he rubbed the back of his head. "Well, probably because I am. I mean your talking about some real freaky deaky stuff here."

"Not really. just go to a Church and you'll find most of it in that press kit they call the Bible and what will it tell you? Shit happens." Damian scoffed. "Please."

Issei was about to say somethingefore Rias spoke "You remember Yuuma Amano?" She smirked at the look Issei shot her. "Of course you do. How could you forget, you two dated for a little while didn't you?"

Damian watched as Issei sat there in stunned silence for several seconds before his hand tightened into a fist. "W-Where did you hear that name?"

When Rias looked like she was about to answer, Issei shook his head. "never mind, I don't want to know. Look I don't know how you know so much about my life but I'm starting to feel a little uncomfortable here so…" he then began to stand up as if to leave. "Maybe we should just-… huh?"

His pause came when Rias suddenly pulled out a photo from her pocket and threw it on the table for Issei to see. The young teen glanced down at the image to see what it was and his eyes widened as he saw it was from yesterday. A picture of him and-

"Yuuma?!" He said with surprise.

Damian glanced down at the photo of Issei with 'Yuuma' and quirked a brow at her appearance. For a Fallen Angel, because no human he's seen looks quite as perfect like she did, she wasn't half bad looking.

Rias nodded at her Pawn's look. "That's right, it wasn't a dream Issei. She's real… she was also a Fallen Angel."

Issei stood there in stunned silence as he stared at the image of the woman that supposedly never existed, according to pretty much everyone else, but there she was, clear as day.

Rias glanced down at the photo with an amused smile. "I love this picture of you two, you remember it don't you?"

Issei nodded at this. "Of course I do, but how is this possible?"

Drake snorted at this "Well, you see Issei, many years ago a magical device was created that allowed one to take these frozen images of the world around them-"

"I know what a camera is!" Issei said with a scowl. "What I mean is, how it's possible for her to be in this photo when everyone else doesn't seem to either remember her or think she ever existed?!"

"Isn't that high school in a nutshell?" Drake said with a chuckle, further annoying Issei.

"We can erase human memory." Rias said, gaining Issei's attention. "It usually ends up being the best thing for everyone, including your parents. After a Fallen Angel accomplishes his or her goal,. they erase all memories and records of themselves from everyone around the target."

Issei blinked, catching onto something. "Wait, what goal?"

"You mean Yuuma's? She needed to kill you." Rias told him, shocking Issei at the reveal that 'Yuuma' asked him out just so she can kill him because it was her mission.

"But... why?" Issei muttered. "Why would Yuuma want to kill me?"

"Because she had to find out whether or not you held something within you that was dangerous or threatening. Once that was verified you were stabbed through the middle with a spear of light." Rias explained.

"That would explain the freaky shit she was saying." Issei said with a frown while he unconsciously rubbed the spot he was stabbed through by Yuuma. "About God and something sacred."

Rias nodded "Yes, you have the Sacred Gear."

Damian's brow raised at this before he glanced towards the boy and narrowed his eyes as he reached out with his senses to see if that was true. After a few seconds, he blinked as he sensed something about the boy before he pulled back. 'Well what do you know, he actually does… talk about a waste.'

"Sacred Gear?" Issei muttered to himself, though everyone could hear what he said.

"Sacred Gear resides in special humans, giving them abilities far above normal. Although most of them can only take effect within human society, some of them can possess the power to harm Devils and Fallen Angels," Akeno explained.

"Issei, you have that power within your body," Rias told him bluntly. "The thing is, this power can be so uncontrollable that it becomes a threat to those in the Underworld." Rias glanced at Damian briefly with a small grin. "Well, to some in the Underworld, others not so much."

She then returned her attention to Issei and nodded towards him. "Hold up your hand.

"Okay, but just telling you now I'm not good at catch." Issei said and did as ordered.

"How? Just catch whatever comes flying at you." Damian said with a slow shake of his head.

Issei grumbled at the man while Rias smirked as she leaned back on her desk, crossing her legs at the knee and causing her skirt to hike up a little and expose more of her legs. A perverted grin appeared on Issei's face as he stared at the exposed flesh with a blush.

"So we're doing this now?" He said as he tried to keep his eyes focused on Rias's face but kept falling down to her gifted chest before his eyes would drop even further back to her legs. "There's uh, there's a lot of pressure."

"It will get easier if you focus." Rias said, though her tone held little amusement despite the smile on her face.

Issei nodded at this as he closed his eyes and began to concentrate. "Focus, focus, focus…"

After a few moments he cracked an eye open before it and his other eye shot open as he was given a small glimpse up Rias's skirt.

Damian frowned as he saw the way Issei was looking at Rias. While he knew the boy was a pervert, and Rias herself didn't seem to mind too much, it still pissed him off that Issei was eyeing up what is to be his future wife like some hormone raging dog. He was about to say something before a slight glance from Rias stopped him, something he reluctantly did as he and the others watched as Issei tried to activate his Sacred Gear.

After several more seconds passed and Issei's eyes found their way to the lower half of Rias's body and that perverted grin grew on his face again, Damian spoke, his voice noticeably darker to everyone in the room. "If you don't advert your eyes Issei, I'm going to rip them out along with what's left of your pathetic excuse of a dick before throwing you into a dumpster."

Issei paled at the man's words as it seemed the lighting in the room darkened and the air grew cold, as if all the warmth was sucked out.

Issei slammed his eyes shut as he tried to focus on something else. "F-Focus… focus…"

After several seconds he collapsed to his knees with a cry of defeat. "It's new use, I'm a weak soul!

"It's okay if you don't get it on the first try, it's pretty hard anyway." Rias said with a knowing grin, causing Issei to blush before he shook his head to clear his mind of such thoughts, for now anyway.

"Are you sure this isn't some mistake? I'm not that cool." He stated with a cough.

Rias was serious though. "A Fallen Angel found you threat enough to try and kill you, it's not a mistake."

"Yeah, and then she put a glowing rod in me and somehow I'm still here." Issei said as he stood up. "How's that work?"

Rias reached down to a small stack of paper that rested beside her on the desk she was leaning on and held it up to him to see. "Do you remember this?"

Damian's eyes focused on the paper and saw it was a flier, causing him to raise a brow in slight confusion. 'The hell is that for?'

Issei stared at the flier for a moment before he nodded. "Yeah I remember it."

Rias nodded in satisfaction at this. "Just before your life ended, you summoned me with your thoughts through this flier. And so, that day you were revived and reborn as an honored member of the house of Rias Gremory. Daughter of the great and powerful Devil, the Marquis of Gremory…"

Suddenly two large Devil wings sprouted from Rias's back, causing Issei to stumble back in surprise as she looked at him with amusement while she placed a hand on her hip.

"Which means you are now my Devil servant." she stated as Kiba, Koneko and Akeno all stood up and came to stand by Rias' side while Damian remained where he was and continued to watch.

"Isn't this so exciting!" Akeno said with a smile as she, Koneko and Kiba also spouted their own wings. "You're really one of us now!"

Issei stated at them all in shock before suddenly his own wings emerged and he stumbled forward in surprise. He glanced at them with a gaping expression while Rias watched on in amusement "We're glad to have you here. Welcome Issei."

It was then that Issei noticed that Damian didn't sprout any black wings like the rest "So, are you a Devil too?"

Damian looked at him blankly for a few seconds before he stood and-

"Oh shit!" Issei exclaimed, jumping back as two wings popped out of Damian's back. However, unlike Rias and the others, who had black wings that were thin, Damian's was a lot bigger and looked like an actual Devil's wings, with the wing membrane being red while the rest was black. (AN: Think of Lucifer's Devil wings from Lucifer S4).

"What do you think?" Damian asked with a smirk as Issei gaped at the wings.

Rias chuckled in amusement while thinking to herself. 'Well, at least this arrangement won't be boring…'

And that's it for this chapter everyone. I hope you all enjoyed it. Yeah, Damian's wings are basically an actual demon's wings, so think of Lucifer's Devil wings from season 4 to get the general understanding of what they look like.
