I know, I know, I'm doing this one again. Not sure why I deleted it in the first place though I can guess, but that's my business. The fact of the matter is, I have brought the story back, and so that balances things out by having two normal DxD fics and two crossover fics. Plus, this does feature my OC from A Betrayed Devil, Damian Mammon-Lucifer.

The story's still the same. OC is the grandson of the original Lucifer, birthed from the union between the son of Lucifer and heiress of a former Extra Demon Clan made into a noble House by Lucifer himself, is put into an arranged marriage with Rias rather than Riser, has a peerage of his own with some beautiful women in it, is a Devil which means he's gonna have the traits and attitude of one so if you don't like seeing him be a little arrogant or dark, then what the fuck are you reading this for? He's a Devil, not an Angel.

Yeah, this story is a harem, it IS DxD of course, which IS a harem anime/manga. Harem so far is listed at the bottom as usual with all my harem stories.

As for when this begins, in episode two of the anime.

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

'So, this is Kuoh Academy, huh? Pretty dull compared to schools in the Underworld.' Thought a recently turned seventeen year old Damian Mammon-Lucifer as he stood outside of the human school in the town of Kuoh, Japan.

Damian Mammon-Lucifer was a young man with pale, yet fair, skin and hazel eyes like his hair is black, with the sides of his head shaved, forming a mohawk out of the hair at the top of his head, tapering off into a point at the nape of his neck. He was currently dressed in the Kuoh Academy boys' uniform, which consisted 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 refused to wear the dress shoes when he saw them. No way in hell was he ever going to wear something as ridiculous as that. It was bad enough when he'd have to look nice and presentable at galas or charity events in the Underworld, yet he did make an effort to look good and dress how he decides. So, rather than wear those ridiculous dress shoes, he instead wore black combat boots.

The reason for Damian being in the human world and attending a human school is because this school also happens to be where his fiancée, Rias Gremory, attends alongside her servants as well as the Sitri heiress, Sona, and her servants. Damian's mother, Sarlith, and Rias' father, Zeoticus feel that it was time the two meet and so Sarlith had Damian attend Kuoh after Zeoticus got the paperwork done to list Damian as a student. Damian had argued, but his mother's glare silenced his complaints. Not that he had anything against Rias, despite having not met her in person yet, the only complaints he had was about attending a human school.

Whatever they'd teach, he already knew it.

However, his mother did managed to convince him in her own stern motherly way and here Damian was, going to a human school that his future wife was also attending.

Damian sighed and shouldered his bag before passing the school gates, taking a look around at the students while noticing how there was way more girls than there was boys. His father did mention that the school used to be just an all-girls school before it turned co-ed. Most guys Damian's age would be over the moon to be surrounded by so many girls as attractive as the ones that Damian 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 briefly as he adjusted his bag and made his way towards the school entrance.

He didn't make it ten feet before two girls stood in his path, blocking his way. Damian for a moment felt annoyance flash through him as he stared at the two brunettes before him. They were fairly attractive with one being a few inches taller than the other and having slightly larger breasts because of it. But the shorter of the two seemed to have a shapelier rear to counter that and her hair was a bit longer than her companion's.

"Can I help you?" Damian asked with a raised eyebrow, managing to keep the thinly veiled annoyance out of his tone.

One of the girls, the one with the short pink hair, blushed as she fiddled with her skirt while taking in his appearance. "Uh, hi. A-Are you new here?"

"Yes." Damian said plainly.

The other girl spoke up. "Would you like a tour of the school? Most newcomers end up getting lost on their first day. Somehow one ended up from the school entrance to the gym when he was trying to find the classroom he was in. Oh! Where are my manners? I'm Murayama, and this is my best friend, Katase? What's your name?"

"Damian." The grandson of the original Lucifer said, inhaling then exhaling as he wanted to get this over with quickly. "Look, ladies, I appreciate your offer, but I think I'll be fine." He made to move past them before he heard a multitude of women and men gasping in surprise as they looked to see two new people enter the courtyard.

Katase looked too and gaped at what she saw. "What the flying fuck?"

"No way!" Murayama had wide eyes. "He had to have done her homework or something!"

Damian, confused at what they were talking about, followed their gazes and saw two people passing the school gates. One was a boy with brown hair, though he didn't catch Damian's attention as much as the girl next to him did.

'So that's her.' Damian thought as he looked at the attractive redhead known as Rias Gremory, his wife-to-be.

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, which consisted 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 a white underskirt beneath it.

Rias seemed to sense Damian's eyes on her, if not the unknown demonic presence, and turned her head to lock eyes with 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 the boy walking with Rias, though Damian tuned them out until Murayama addressed him.

"So... do you want that tour?" She asked with a grin, one shared with Katase.

Before Damian could respond, he picked up the ever so subtle hint of lust coming off the two girls and it was directed towards him. Damian exhaled through his nose and looked at them blankly. "Listen, girls, I appreciate that you want to have a 'tour' and find somewhere private to have sex with me rather than attend the first two or maybe three periods of the day, but I'd rather get to class and get this day over with."

The girls' expressions fell, which made Damian hold back the urge to sigh again as he rubbed the bridge of his nose. "Get back to me on Friday and I'll see about taking you up on that, okay?"

"Really?" Katase asked with a hopeful expression that was mirrored by Murayama as Damian walked past them.

"Sure, see you Friday... not." Damian said, muttering that last part under his breath. Sometimes he loved and hated his good looks, though his pride as a Devil would never allow him to admit he hated his good looks. He entered the school building just in time to hear the boy that was with Rias exclaim to two of his friends about how he got to see Rias naked.

Damian stared blankly at the scene. 'I'm going to hate it here, I can just tell.'

Rias walked up the stairs to the second floor of the school, her eyes closed as her thoughts centered around her recent addition to her Peerage. However, she opened her eyes when hearing a familiar voice. "You seem so sure about him." She looked to see a young woman around the same age as Rias, had a slim figure, black hair styled in a short bob cut and violet eyes which she hid behind a pair of red glasses. Her name was Sona Sitri, the Student Council President and the third most popular girl under Rias and Rias' Queen Akeno. She was also Rias' childhood friend and rival. "Hello Rias."

Rias gave her a smile and a nod as she approached the young beauty. "It's good to see you too Sona"

The two Devil heiresses looked down at the floor below them, their eyes on the infamous Perverted Trio as Issei was bragging to his two friends. "I've never seen you take on someone so impulsively." Sona commented. "What's so special about this one?"

"Never seen you take on someone so impulsively." Sona said as the two looked down towards Issei as he bragged to his two friends "What's so special about that one?"

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."

Sona stared at her friend for a little while longer before directing her eyes to the Perverted Trio, who were now playing rock, paper, scissors for some reason. "I see..." Her eyes then shifted towards a boy around the same age as the two girls, watching as he gave the trio a blank look before walking off down the hallway. Even from here, Sona could feel the dark and powerful energy from him. "So that's him. The one you're betrothed to. Damian Mammon-Lucifer."

Rias' gaze shifted to the Devil in question and 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. But, considering he's a direct descendant of the first Devil himself, I shouldn't be too surprised. At this rate, he'll trump even your brother before we graduate. I've even heard that he, just like his father, inherited Lucifer's connection to Light Magic given that Lucifer was the first Angel."

Rias hummed in response as she watched Damian until he turned a corner and was out of her sight. The bell soon rang and Rias looked towards her friend. "See you later Sona…"

"Same." Sona responded with a nod and turned to leave as they went to their respective classes.

'This. Is. So. Boring.' Damian thought to himself as he leaned his clenched fist against his cheek, looking almost bored as he stared out of the window while vaguely paying attention to the teacher. Damian didn't last twenty minutes into the class before he became bored, mainly because he discovered that most of the material they'd be going over today were things that he already knew.

It was like that for most of the day, a boring class with subjects Damian already knew enough about and having to deal with teachers repeating themselves because of the other students being idiots or not paying attention. Even for a Devil, it was pretty boring, bland and irritating. Even lunch didn't offer up anything interesting, aside from girls staring at him lustfully or 'whispering' about his good looks while guys glared at him in envy.

And he had to get used to it since he'll be here until... whenever. Well, he supposed he'll be here until Rias graduates and he would take the quick oppertunity to drop out though he was tempted to do that just now if not for the fact his mother would scold him for it.

When the end of the last period finally came with the sound of the bell ringing, Damian almost hit the table in relief as he stood up and grabbed his bag, wondering whether to head to his residence in the town or go see Rias, only to find the redhead standing in the open doorway of the classroom.

"Damian... Mammon?" Rias asked as she glanced towards Damian.

"Yes." Damian nodded.

"Can we talk?" The Gremory heiress asked as she leaned against the doorway.

Damian nodded as he shouldered his bag while seeing many guys in the room glaring at him jealousy or looking at Rias in lust and awe, while the girls were staring at him in either lust or envy, with even Rias getting similar looks from the girls.

'There is something seriously wromg with these humans.' Damian thought with a shake of his head as he followed Rias out of the classroom and they walked side-by-side.

"Enjoying your first day?" Rias asked with a smile.

"I have a neutral opinion on that. For a human school it's... something." Damian said with a small shrug. "I suppose I'm just used to schools in the Underworld, having learned everything I need to, including what they teach here. The only thing schools in the Underworld don't have is humans operating on some caveman personality and trying to be top dog or something. And don't get me started on two girls that wanted to have sex with me."

"Don't look too into it, it'll make your time here less complicated. Just give a smile and nod, maybe a nice comment or a polite rejection and you'll be fine." Rias advised as they exited the school building and were now making their way across the courtyard.

Damian looked at her with a raised eyebrow. "Is that what you do with guys and girls that ask you out?"

"Maybe." Rias shrugged with a smile as they approached a three story building, with the third story serving as a clock-tower. It has been painted white with a black roof with vines creeping up to the second story. "Sometimes they are too busy staring at my breasts to hear my words and only pay attention when I walk away from them before realizing what I've said. The same with my Queen, Akeno."

"Humans." Damian sighed, shaking his head. "It would be better off just putting them in their place with violence."

"No." Rias stopped and gave Damian a serious look. "To harm a human is something without exposing us, to kill one would get the attention of the Church or even the Fallen Angels. Maybe a punch or two is optional, but not outright killing."

"Like I'm afraid of those bible-reading idiots or those rejected pigeons." Damian remarked with an eyeroll before he exhaled. "Fine. I suppose I'll only punch or kick a human if they try anything with me because of some primitive instinct that demands they try to be alpha caveman or something."

"Suppose that's as good as I'll get with you." Rias sighed with an amused grin as she and Damian finally entered the main club room that she and her Peerage use. The interior of the room 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 shower, and a large Gremory Family magic circle is also there to allow teleportation to and from clients. "Welcome to the Occult Research Club."

Damian glanced around the room, taking it in with a keen eye. "Hmm. Impressive. So this is where you and your servants meet."

"My Peerage." Rias corrected gently.

"What's the difference?" Damian countered, stopping near one of the candles and staring at it intently as the flame flickered and almost went out before brightening again. "They follow everything you order, and you are their master."

"You should know that my household sees our servants like family, so we don't treat them like they are beneath us." Rias remarked, crossing her arms under her breasts as she leaned against her desk.

"Nor do I look down upon my own. A Devil I may be, I'm not as cruel or heartless like the older generation from the Old Satan Faction or even some of today's Devils. My parents raised me to be better than that but still take pride in what I am and to not let anyone think they are above me." Damian said. He took his bag off and placed it on the floor next to one of the couches before looking at the redhead. "So... how do you want this to work between us?"

"I haven't really decided yet." Rias said with a sigh. "To be honest, I thought we'd meet after I graduated from school and be in college."

"Same, but my family and yours decided it was best we meet earlier and get to know each other." Damian said, sighing as he punched the bridge of his nose. "At least they are letting us decide how our marriage will go, and when we set the date. So... when do you want to do this?"

Rias was silent for a few moments as she thought it over. "Do you want to wait until we're finished with school? Granted it'll be a few years but for people like us it might as well be a few hours."

Before Damian could reply, the door opening caught their attention as a girl entered, said girl blushing and giving a sheepish chuckle upon realising she may have interrupted something important.

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

Her name was Akeno Himejima, Rias' Queen and the second most beautiful girl in Kuoh Academy. She had a voluptuous figure, very long black hair and violet eyes. Her hair was tied in a very long ponytail, reaching all the way down to the floor with two strands sticking out from the top and sloping backward, with an orange ribbon keeping it in place. Like most of the girls at Kuoh Academy, she wears the customary Kuoh Academy girls' school uniform, along with black calf-length socks.

Rias cleared her throat and gestured to the male Devil in the room. "Akeno, this is Damian Mammon-Lucifer, the one I told you about in regards to the arrangement my family made with his years ago."

Akeno's eyes widened at this." Oh.." She turned to Damian and bowed. "Welcome. I hope you've had a pleasant experience so far at Kuoh Academy and in the human world in general."

"Week's not over yet, so I'm still forming an opinion." Damian said in a dry tone. "Besides, this isn't my first time in the human world." He made his way over to the couch and sat down with a sigh. "So, what do you do here? Do you actually study the Occult?"

"Yes, mainly for appearances sake. But it's a cover to hide our real activities." Rias said with a smile. "I'll explain it better when the rest of my Peerage arrives, including my new Pawn."

"Whatever you say." Damian nodded as he relaxed on the couch while Akeno walked over to sit next to him, crossing her legs at the knee. She took in his appearance and liked what she saw as well as sensed.

"So, Damian, do you have a Peerage?" She asked curiously.

"I do. I have a Queen, two Knights, two Rooks and a Bishop. They're either in the Underworld or busy getting our accomdations sorted since we'll be staying at the penthouse in town." Damian said.

"You mean the one that was recently put in place a week and is also going to be a nightclub?" Rias asked with a raised eyebrow.

Damian shrugged. "My Rook, Tifa, ran an establishment before I met her. It's called Seventh Heaven, and she didn't have much funds to make a big-time establishment until I came along and helped with that. Now it's went from as small as a bar or tavern to a nightclub."

"Well, aren't you the gentleman?" Akeno giggled playfully. "Helping a lady get her job to bigger heights before making her your servant."

"She has potential, I saw it and offered her a place." Damian said.

"Are you looking for any more potential Peerage members?" Rias asked as she began to undress. "I assure you, this school plenty of candidates to choose from when it comes to Pawns and Bishops. I can help you find them."

"If you want to help, sure. But I'm in no real hurry." Damian said as he watched as Rias disrobed.

Akeno saw this and giggled. "Enjoying the sight, eh? Taking in the image of your future wife? Mapping out where you'll be placing your tongue, hands and 'other' parts of you?"

Damian looked at her dryly. "She's the one who decided to start stripping in front of us."

Akeno giggled again before leaning close to his ear, her breath tickling his skin. "Do you want to join her in the shower? The rest of her Peerage won't arrive for another hour or two, and you do look like you could use some 'relaxation'. Maybe she can help you with that..."

"Akeno, stop teasing him." Rias cut in with a amused chuckle as she stood in her underwear, in the midst of unclipping her bra. "If he wants to join me, he's more than welcome of his own free will."

Damian blinked at that and looked at her as she bent over to remove her lacy black thong, giving Damian a view of her nicely toned ass cheeks. "Really?"

Rias stood and turned to him, uncaring that she was presenting her breasts and pussy to his eyes. "Damian, we're going to be married at some point in the future. We might as well get used to the fact we'll be seeing each other naked and having sex at some point as our families no doubt want a child born from our union."

Damian stared at her, not so much drinking in the view as a quick glance already did that. "How about I take you out to dinner first before we go towards the intimate stuff?"

"I'd like that." Rias said with a soft smile before she stepped into the shower, closed the curtain and the water was soon heard running.

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. And they say shivery is dead. Most other Devils your age would've instantly taken her up on that offer."

"I'm not most Devils, my dear." Damian countered. "And I'm not run by lust like most sex-hungry Devils seem to be these days. We may be creatures of sin, but we should express control over our basic, carnal desires from seeing a woman's body. I'm not the type to demand a woman lay with me or anything like that, I'll look, but I won't force myself. I was raised to show respect, you can thank my parents for that. If they hadn't, I'd probably be like an animal sticking my dick into every female that I see."

"Oh my." Akeno giggled with a faint blush on her face before the door opened and 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 petite girl with white hair and gold eyes. The front of her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair. She was dressed in the Kuoh Academy girls uniform, excluding the shoulder cape.

Koneko simply shrugged before looking at 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. Isn't he handsome?"

Koneko simply shrugged again before she walked over to the opposite couch to take a seat, helping herself to some sweets that were laid out on the table in-between the couches.

"Koneko's our Rook, the tank of our team." Akeno explained to the grandson of Lucifer while leaning her head on his shoulder. "She's a bit distant, but she'll come around once she's used to you."

"I see..." Damian stared as he and Koneko stared at each other with blank expressions, having seemingly set a silent staring challenge between them without the need for words.

Several minutes passed as Rias continued her shower while Akeno excused herself to go fetch Rias some dry clothes. Damian's staring contest with Koneko ended when the door opened, bringing his attention to it, and he looked to see a blonde-haired guy, which must be the Kiba Akeno mentioned a while ago, enter with the boy that walked to school with Rias this morning. Damian was sure his name was Issei.

Damian's eyes narrowed as he sensed something with Kiba, it felt almost... holy.

He watched as Issei looked around with confusion."What's going on? Where are we?" He looked at the couches, spotting Koneko sitting on one of them. "Wait, I think I know her."

"Oh?" Kiba sounded surprised. "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 sweets. Issei then 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, unaware of Akeno silently slipping by him.

"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.

"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.

"You seriously need a girl or your balls to drop." Damian remarked dryly with a roll of his eyes, drawing Issei's attention to him.

"W-Who are you?" Issei asked with a frown, having never seen Damian around campus before.

"Damian Mammon-Lucifer, Hell incarnate, Prince of Darkness, but you can just call me Damian." The male Devil heir said as he leaned back in the couch with his arms crossed over his chest.

A giggle came from Akeno. "Now, now, Damian, no need to be rude or try and scare him." Akeno looked at Issei, who was staring at her in both awe and nervousness at seeing the second hottest chick in school. "Don't worry, I won't bite. You're the new guy, right? It's nice to meet you." She bowed to him, making her breasts bounce. "There's nothing to worry about. Everyone here is super nice. I'm Akeno, i'm the vice-president."

"Uh... I'm Issei Hyoudou and I promise I'm not always this awkward." Issei said with a stutter, his eyes flicking to her breasts before looking away.

"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 of 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 teen a dismissive grunt as Akeno sat on one side of him and Kiba on the other, though with ample space between both of them, while Issei sat down next to Koneko who kept one eye on him as she ate her chocolate treat. Rias sat on the edge of her desk, looking at everyone in the room before focusing on Issei.

"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, catching Damian's attention as he silently listened.. "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, most of what Rias said you can find in that overblown press-kit they call the Bible, where everyone always looks for the answers." Damian said with a scoff. "And it'll tell you one thing; shit happens."

"An apt way to put it." Akeno giggled.

"You remember Yuuma Amano?" Rias suddenly asked, catching Issei's immediate attention. "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.

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."

Damian glanced at the picture, taking in the Fallen Angel's appearance. She was quite pretty, with long dark hair that matched Akeno's hair color, and seemed to come off with innocence. Then again, that was most likely a disguise and not her true self. But for a Fallen Angel, disguised or not, she was quite pretty.

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?"

Damian 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?" Damian 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... Raynare 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 Raynare. "About God and something sacred."

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

Damian's eyebrows shot up at this before he extended his senses to see if it 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. "Hold up your hand"

"Okay, but just telling you now I'm no good at catch." Issei said as and did as ordered.

"That sounds stupid." Damian said bluntly. "Somebody throws something at you, your first instinct is to catch it. It's natural with everybody."

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 tired 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 and force them down your throat and rip them straight out of your ass along with whatever excuse for a dick you have."

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!"

"Got that right." Koneko said with a scoff, causing Issei to glare at her while Rias smiled at the young boy.

"It's okay if you don't get it on the first try, it's pretty hard anyway." She 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 slumped.

"A Fallen ANgel found you threat enough to try to kill you, it's not a mistake." Rias said seriously.

"Yeah." Issei scoffed. "And then she put a glowing rod in me and somehow I'm still here, how does that work?"

In response, Rias held up a leaflet or a flyer with the Gremory symbol in the middle of it and the words 'Your wish will be granted' at the top. Damian raised an eyebrow at it but said nothing. It wasn't his place to comment on how Rias and her Peerage do their contracts. "Do you remember this?"

"Yeah...?" Issei nodded.

"Before your life ended, you summoned me with your thoughts through this flyer." Rias said. "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's servant." She stated as Kiba, Koneko and Akeno all stood up and came to stand by Rias's 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."

Issei stared at them for several minutes, gaping like a fish, before he then noticed Damian hadn't stood or sprouted wings. "What about you? Are you a Devil?"

Damian looked at him before he stood and unleashed his wings. However, unlike other Devils who had thin, bat-like, black wings, Damian had a true pair of demon wings with a blood red membrane and black bony structure, with sharp tips on the end.

"Let's just say I'm a descendant of Lucifer himself and attained attributes that not all of his children and descendants inherited." Damian said with a small smirk as his eyes glowed red. His eyes then returned to their hazel colour while he retracted his wins. "My name is Damian Mammon-Lucifer, grandson of Lucifer himself."

"Your grandfather's Lucifer?!" Issei shouted in shock.

Rias exhaled with amusement at Issei's reaction before glancing at Damian. 'Well, at least this arrangement will be quite interesting. Better than the one with Riser Phenex at least...'

And that's it for the first chapter. Yeah, Damian's wings are Lucifer's Devil wings from season 4. They look awesome and befitting someone who is of Lucifer's bloodline. Not all have those wings, I'm trying to show differences here even if that's difficult. But hey, it's a Fanfiction story centered around a harem anime'manga featuring Devils, Angels, Fallen Angels, and sexy, big-breasted women. At some point common sense was thrown out the window it's development... I think.

Anyway, the harem and Peerage.

Harem (So far): Rias Gremory, Akeno Himejima, Raynare, Kuroka, Yasaka, Serafall Leviathan, Gabriel, Irene Belserion (Fairy Tail), Erza Scarlet (Fairy Tail), Raven Branwen (RWBY), Tifa Lockhart (Final Fantasy), Moka Akashiya (Rosario + Vampire), Mio Naruse (Testament of Sister New Devil).

Maybe (Ideas and scenarios for these women are needed): Grayfia Lucifuge, Venelana Gremory, Kalawarner, Katerea Leviathan, Seekvaira Agares, Yubelluna, Xuelan, Karlamine, Rossweisse, Xenovia,

I need ideas for the women in the 'maybe' section, not simply "Pick them because they're hot".

King: Damian Mammon-Lucifer

Queen: Irene Belserion

Knight 1: Erza Scarlet

Knight 2: Raven Branwen

Rook 1: Tifa Lockhart
