I know I had High School DxD: The Legend of the Son of Sparda be a replacement for this fic, but since I've brought back A Betrayed Devil, I feel it's only necessary to bring back the alternate version of that fic featuring the same character, Damian Mammon-Lucifer. And what I mean by alternate fic, is that in this one Damian has a different origin. He's still a Devil, yes, but was born sometime AFTER the Devil Civil War, so he'll be the same age as Rias.

In fact, he'll be engaged to Rias rather than Riser Phenex being the one engaged to her.

Damian has several Peerage members who will be introduced in this chapter, which is more of a prologue or introduction chapter, as I feel it needs an action scene to start it off. As for when this story begins in terms of canon, it's going to start on the day Issei finds out he's a Devil, when he wakes up to find Rias in bed with him. So basically during the second episode of the anime since I haven't read the manga.

And yes, this is also a harem fic, no surprise there.

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

It was very quiet at night in New York City, save for the engines of vehicles passing on the streets even this late at midnight but some people do work and finish at such times. However, New York had it's quiet nights, which were rare given this was the City That Never Sleeps. Most of the time, at night, the streets would be filled with loud shouting, police sirens ringing through the streets, gunfire going off, thugs preying on the innocent, murderers commiting murder and rapists committing rape.

However something unnatural laid within the city, hidden in an abandoned, dusty old warehouse located in Harlem, near a shipyard. Nobody a[proached, since there had been much disappearances near that warehouse that nobody would dare go close. Not even the police would investigate after five officers went missing... within the span of one night.

On this night, however, something else stalked the streets and was making his way towards the warehouse casually

The person was a young man in his late teens, about seventeen years old from the looks of him, with neatly combed, slicked back black hair. The teen had hazel eyes that stared blankly at the warehouse, fair skin, and was clad in black cargo pants, black combat boots, a short-sleeved black shirt, black biker gloves and a black leather jacket.

The teenager looked at the warehouse windows for a moment, then hummed quietly to himself as he walked straight up to the doors and pushed them open, allowing the moonlight to stream in through the open doorway and illuminate the interior of the building.

As well as it's tenents.

Monstrous, grotesque creatures who looked like a mix of human and other creatures, some with spider legs, others looking like a beetle, it was truly a sight that belonged in nightmares. One would say, if they were religious, that these creatures ascended from Hell.

Oh, how right they would be at that.

The teenager's eyes scanned the room, taking in each monster that stared at him with a mixture of look; hunger, disdain, anger, hatred, even lust. He ignored them all to focus on the head monster that sat on a makeshift throne. And like the other abominations, he was as ugly looking as them, appearing like a scorpion and spider were merged with a human.

The monster chuckled. "Look who it is, Damian Mammon-Lucifer! The grandson of the original Lucifer himself!"

Damian tilted his head as the other monsters stirred at his name. "You know who I am." He stated more than asked.

The creature, a Stray Devil, chuckled. "Yeah, I met your mother once. You know, she has some nice, big tits that I would love to squeeze my face into while I piund her pussy into submission." He growled darkly as he leaned forward, saliva dripping from his mouth and onto the floor. To his credit, Damian barely reacted to the lecherous comments made towards his mother. "What do you want, little Devil?"

Damian cleared his throat before declaring loudly to all Stray Devils watching. "Malgross the Defiler! For the murder of several humans, putting the secrecy of our world in jeopardy, committing countless crimes against all of Creation, including the murder of your master, and amassing an army of Stray Devils, and by order of the Satans, I hereby sentence you... to death."

In response, the Stray Devils all laughed as Malgross leaned back on his throne. "You come in here, alone, threaten me... and think you're just walking out of here?"

"Yeah." Damian nodded casually, hands on his hips.

"I'm gonna count to three." Malgross snarled angrily as he glared at the pureblood Devil before him. "If you're still standing here, I'm gonna defile your corpse in ways you can't even imagine. Have my boys take turns in ripping your flesh, and maybe have the women take turns fucking your corpse. Devil corpses are their favourite. One-"

In the blink of an eye, Damian whipped out two pistols. "Two! Three!"

BANG! BANG!

Malgross roared in pain as two bullets were shot right through his eyes, blinding him, the blood gushing out the holes in the process while Damian turned to address the other Stray Devils. "Sorry..." He aimed upwards without looking and fired off another shot, getting Malrgorss in the forehead and killing him instantly. "We're in a hurry."

He twirled his guns and put them in their holsters underneath his coat on the back of his waist. He smirked as he watched the Stray Devils begin approaching, looking ready to rip him apart for killing their leader.

"Oh... and I'm not alone." Damian said with a smirk.

A red blur slammed through the ceiling and into the ground, the resulting shockwave blasting a few Stray Devils back while a few were infinerated by a wave of energy magic. When the smoke cleared away, a woman was shown to be standing beside Damian.

The woman was tall, jaw-droppingly beautiful with a voluptuous figure. She had thickly braided, bow-adorned, scarlet hair. Her two front braids have two golden ornaments near the upper sections; she also wears two U-shaped earrings (one on each ear), and wears red lipstick.

For clothing she wore a risqué version of the typical witch's garb. Her black top has a diamond-shaped opening, exposing a portion of her breasts, and a heart-shaped pattern around the borders. It extends down to the naval of her stomach where it meets a large angular scar, is draped over by a dark-colored cape with a light-colored inside and two medallion gold-like ornaments, and is held together by a golden chain. Not left bare, too, her neck is decorated by other small cloth-based accessories, including a wide bow. Additionally, she wears an elongated black loincloth with the combined symbol of the Lucifer and Mammon Houses emblazoned on its front, having white borders on its edges and being connected to another cloth piece with the very same heart-shaped design. She also wears black thigh-high boots with heels that have a white-colored border near the top and gloves of the same color and design, only having claw-like extensions. Her black witch's hat is much larger than her head and possesses dreadlock designs with white bandaging near its ends. It also has a fur lining near its edges.

This was Irene Belserion, Damian's Queen in his Peerage.

Next came the caw of a bird, as a raven flew in via an open window. In the blink of an eye, the raven transformed into a woman who unsheathed a red katana and slashed through several Stray Devils, decapitating them, and reappearing on Irene's right side. She straightened up, sword held at her side in a stance.

Like Irene, this woman was as beautoful as she is, with pale skin, long jet black hair tied by a red bandanna and loosely done up in a ponytail with the ends resembling curved black feathers, along with dark crimson eyes. Her attire consisted of a shallow cut black and red dress with black shorts underneath, with series of beaded necklaces and a belt that wraps around her waist and carries her weapon's sheath. Attached also is a long black object that is either fur or feathers, with a red and white bandana material like hanging from behind her. Her forearms bare red armored gauntlets that protrude outwards and solid black gloves, along with black mid-thigh high leggings and black heels with red soles.

This was Raven Branwen, Damian's Knight. A skilled swordswoman even before she became a Knight.

Soon enough, several more ladies dropped in through their own means, taking out several Stray Devils in the process, and making them back up in fear as they were face to face with the infamous 'Devil of Death' and his Peerage.

On Damian's left was a girl a couple of years older than him, nineteen actually. She had long scarlet red hair, warm brow eyes, and a voluptuous figure that easily rivaled the likes of Irene, Raven and the other girls around her. She was currently dressed in a simple white shirt that seemed to be a bit small on her, showing part of her midriff and blue skirt that ended just halfway down her thighs, showing off an amazing set of legs, and a pair of knee-length boots. In her hand was a sword.

This was Erza Scarlet, Irene's daughter and Damian's second Knight.

The next girl, who stood beside Erza, was as gorgeous as she was, was about the same age as her, maybe a couple years older so in her early twenties at was a real beauty, which made many men (and even some women) blush at the sight of her. Standing a little over five feet, she had long, dark-brown hair that could've easily been mistaken for black if the light wasn't hitting it right. Said hair fell to just below her waist and was tied near the end to resemble a dolphin's tail. Her eyes were an exotically dark red and she wore a white tank top, a black, pleated mini-skirt with a belt and suspenders, equally black shorts underneath, red and black gloves that extended to her elbows, and red-black boots with black stockings.

Her name was Tifa Lockhart, Damian's Rook.

The next woman beside Tifa was an equally gorgeous young woman the same age as Damian, with long crimson hair reaching her waist and pink eyes. Aside from the red hair, she has been noted for having a distinctly slender yet curvaceous figure with enormous, bouncy breasts and sizeable buttocks. She was clad in black jeans that clung to her shapely hips and toned legs like a second skin, a short-sleeved white shirt with a dark blue jacket over it.

Her name was Mio Naruse, Damian's Bishop.

Next, on Raven's right, was another woman who was extremely beautiful. She had long, flowing black hair that went all the way down to her lower back and golden eyes that looked familiar. She was wearing a tight, black kimono with a red interior and a yellow obi that accentuated her large breasts. She was also wearing an ornately decorated headband and a set of golden and black beads around her waist where her kimono had an opening, showing off her long, smooth legs. She was barefoot as well but that didn't seem to bother her at all. What was really eye-catching was the pair of black cat ears on top of her head and two black tails swishing back and forth.

This was Kuroka, former Stray Devil and SS-Class criminal until Damian helped to prove her innocence in the murder of her former master. She was also his second Bishop.

And finally, beside Kuroka, was another young woman of cold beauty. She was a tall fair-skinned girl with knee-length silver hair that has bangs swept to the right side, and her eyes were red irises with slit pupils. A noticeable thing about her is that her breasts and buttocks are large enough that they are too big for her clothes, which consisted of a simple shirt, black skirt, and knee-length combat boots for women. Her shirt exposes a small portion of cleavage while her skirt allows a healthy amount of her bottom to slip out.

This was Moka Akashiya, Damian's second Rook, as well as a Vampire.

"Like I said..." Damian said, opening his hand and in a flash of dark and bright light, a sword appeared in his hand. The sword was a silver-colored longsword. The blade is long and double-edged, with the forward-facing edge curving outward to form the guard. The handguard is is designed to resemble a vortex that reverses at the center of the handguard. The pommel carries a round piece that almost resembles a face. The sword's name was Mortem, which was Latin for 'Death'. "...I'm not alone."

And with that, they attacked the Stray Devils...

And that's it for the first chapter everyone. Let me know what you think in the reviews please, and if you're already enjoying this then be sure to favourite and follow to get notifications (Although gmail notifications from Fanfiction seem to be down at the moment... again).

Anyway, as for Damian's Peerage so far.

King: Damian Mammon-Lucifer (OC)

Queen: Irene Belserion (Fairy Tail)

Knight 1: Erza Scarlet (Fairy Tail)

Knight 2: Raven Branwen (RWBY)

Rook 1: Tifa Lockhart (Final Fantasy remake appearance)

Rook 2: Moka Akashiya (Rosario + Vampire)

Bishop 1: Mio Naruse (Testament of Sister New Devil)

Bishop 2: Kuroka (DxD)

Yeah, that's Damian's Peerage so far. I doubt I'll go all the way to getting all fifteen pieces for it, but that could change. He's already got some powerful and strong servants in his Peerage, and I get that they are all women, but this is DxD we're talking about. Plus Damian looks for strength and power in those he picks.

The harem might be a bit big... but meh.

Harem: Rias Gremory (Alpha and main girl), Akeno Himejima, Raynare, Kuroka, Yasaka, Serafall Leviathan, Venelana Gremory, Irene Belserion, Erza Scarlet, Raven Branwen, Moka Akashiya, Mio Naruse, Tifa Lockhart.

Those are who is confirmed for the harem, the ones below this text are those I'm considering but need ideas on how to fit them in, which is where you readers come in. Give ideas for these ladies, please.

Kalawarner, Chisato Hasegawa, (Testament of Sister New Devil) Olga Discordia (Kuroinu), Chloe (Kuroinu), Cellestine (Kuroinu), Kushina Uzumaki (Naruto. Was thinking of her being Yasaka's half-sister, but I'm also thinking of using it for my Godzilla/DxD crossover as well), Katerea Leviathan,

So let me know any suggestions and ideas for these women to be brought into the harem, their romance with Damian, and don't simply give me Because they're hot and sexy".
