I'm not answering the reviews for this chapter, because I want to address the reviews I got about Damian's character as well as his fight with Raynare.

First off, Damian is strong and powerful, befitting a descendant of Lucifer himself. Yes, he could've easily killed Raynare without so much as breaking a sweat or like swatting a fly. But he was holding back a lot because he's a Devil, he's a Lucifer, he's arrogant and that often stops him from just ending a fight. But if he did that for every opponent he faces, then there's not much of a story, is there? Plus, he saw potential in Raynare, which did hold him back from just killing her the moment she started to annoy him. And he had his reasons for not killing her. She has information.

As for the fight, he was winning until she spat blood right in his eye. Anyone would be distracted by that. Raynare took advabtage of that and managed to bury him, taking him out temporarily but she knew it wouldn't keep him down. What did you expect him to do when getting something spat into his eye? For it to bounce off like he's a force field or something? Grow up!

And also, I'll make him dress the way I want him to look, to try and at least blend in rather than dress like a rich guy. And he didn't follow Issei like a dog, Rias requested he be around just in case the Fallen Angels attacked Issei again. And it was by chance he stumbled onto Raynare confronting Issei and Asia.

If anybody is reading this fic just to watch the OC defeat everyone in his path without trouble and get all the girls like it's some porno, then stop reading and go find something that does exactly that because this isn't that kind of story.

If you don't like the way I do my stories, then stop reading them. Nobody is forcing a gun to your head and making you do it.

"UGH! This is the worst!" A female Fallen Angel complained as she sat on a tree branch that overlooked the abandoned church the Fallen Angels were using as their base.

The Fallen Angel was a girl with blonde hair which was styled into twin-tails and blue eyes. She wore a Gothic Lolita attire, which consisted of a black dress with white frills, a large black bow on the front, and a green jewel embedded on the collar, white thigh-high socks with suspender garters, black set of frilly panties, and black shoes. She also wore a large black bow on top of her hair.

Her name was Mittelt, and she was incredibly bored out of her mind right now, being on watch duty by Raynare's orders.

'Damn whore. Thinking because she's the leader and hotter, she can boss me around?' Mittelt thought with a scowl, before complaining out loud again. "Standing guard is the most boring thing ever."

Her complaints came to a halt when the area lit up with a red magic circle, drawing her attention. She watched as Rias and Akeno appeared from it, and smirked with dark glee at sensing the demonic energy coming from them, identifying them as Devils.

"oooh, ask and you shall freakin' recieve." Mittelt hopped down from her perch and faced the two women. "Hi there. I'm Mittelt, and I'm totally the most awesome Fallen Angel in the history of ever!"

Akeno looked amused. "This little girl is really into herself, isn't she?"

Rias also had an amused smirk on her face, her arms crossed underneath her bust. "My servant sensed that you were nearby. Since you're out here standing guard, you're people must be worried about an attack."

"Worried?" Mittelt laughed and waved her off. "No, we're just in the middle of a super duper top secret ritual and don't want you Devils interfering."

"Not to burst your bubble but a couple of members are on their way there right now." Akeno said with a grin.

"They're what? Are you flipping kidding me?!" Mittelt said with shock.

"Nope." Akeno said with amusement. "And they're not gonna be discreet about it.

Mittelt groaned loudly before she turned away from the two Devils and stomped on the ground several times in frustration. "I hate Devils, I just wanna squish their ugly stupid devil faces. UGH! Whatever, let them do their worst. It's not like they can stop us, there are way more of us than there are of them!" She turned back to the two Devils, smirk back in place. "So why are you here? I hope it's not for some sort of rescue operation 'cause if so you'll have to deal with me first. I may be little, but I promise you this much; I can pack a punch."

"They're on their own." Rias said with a bored tone, causing Mittelt's eyes to widen.

"Huh?" She asked in confusion.

"We won't be making any attempt to rescue them." Rias smiled. 'With Damian there, I have all the assurances of their safety guaranteed.'

"So what? you're just gonna sit back and watch?" Mittelt asked, confused.

Not too far off from where Rias and Akeno were, Damian was with issei, Kiba and Koneko, looking at the closed doors of the church.

"Man, can you feel that?" Issei asked.

"Yeah, no kidding, there must be a ton of priests in there." Kiba said as he gripped the handle of his sword.

"Seriously." Issei said before he gave the others a thankful smile. "I'm glad you guys are here."

"Well, hey. you and I are buddies right?" Kiba said with a friendly smile before it fell and his face became more serious, his eyes colder. "Besides, Fallen Angels aren't exactly my favourite thing in the world. The truth is, I hate them."

Damian looked at him out the corner of his eye before he looked at the church and cracked his neck, then started to approach the church which drew Issei, Kiba and Koneko's attention.

"Hold on! Issei hissed after him. "Don't just go in!"

Damian rolled his eyes. "They already know we're here." His trench coat billowed softly in the wind, and swayed with his movements.

He had switched out of his earlier clothes for something he liked to call his more signature and common choice of attire. His clothing consisted of a black, leather long trench coat with a hood that was down. Underneath that was a short-sleeved black top. For his lower body, he wore a pair of black cargo pants and black combat boots. He also wore a pair of black fingerless gloves.

As the others jogged up to join him, Damian raised his right leg then sent his foot into the wooden doors. The result was the wood splintering into hundreds of small pieces as they shattered under Peter's punch. Without a second thought, Damian entered the building with Issei, Koneko and Kiba right behind him and they examined the room.

The cross on the dais was damaged along with numerous statues of what Damian figured were of either saints, Angels or even Jesus. Issei made a comment about it looking creepy as they moved deeper into the church before the sound of clapping could be heard. The four Devils stopped as Freed emerged from the shadows and walked in front of them.

"So, we meet again. Glad you could make it." He said with a grin on his face. "I bet I'm a sight for sore eyes, huh?"

"More like a sight that makes me want to carve my eyes out so I don't have to look at your fucking face." Damian rolled his eyes.

"Well, I wouldn't expect anything less from a shitty Devil like you." Freed chuckled, then grinned darkly at them. "Here's the thing, I pride myself on the fact that I never have to battle any Devil more than once. And yet here you are, just rubbing it in. If there's one thing I won't abide, it's being mocked by maggot Devils in the house of God." He drew his Light sword and holy gun. "So what do you say? Let's finish this! The thought of tearing away your flesh and eating it piece by piece makes my mouth water."

"You're not even worth my time as well, asshole." Damian sighed, pinching the bridge of his nose before his expression went dark and serious. "We're here for the nun."

"Yeah! Where's Asia?" Issei demanded, stepping up with a glare at Freed.

"Oh right, you mean that dirty Devil loving whore of a sister." Freed said as he looked over his shoulder at the door he came out of. "All you have to do is go to the basement. She's right beneath the alter we're currently standing on."

"Downstairs." Kiba said as he drew his sword.

"RIght." Issei said while Koneko moved towards one of the rows of seats.

"But first you have to go through me!" Freed said with a crazed grin.

Damian shook his head. "No, we don't. I don't feel like wasting my time with an insignificant parasite who's trying to compensate for small dick syndrome, and was most likely touched by priests growing up, so I'm just gonna let her deal with you."

Freed blinked. "Deal with wh-OOF!"

From behind, he was dropkicked by a pair of armoured boots, sending him flying and slamming into the wall as a girl stood in his place after shooting out of a silver magic circle.

The girl in question was a young woman around nineteen, nearly twenty, years old, with long, scarlet hair, brown eyes and a slender, voluptuous figure. Her attire wasn't clothes, but armor made of silver metal. The upper part of this armor only consists of a small, revealing breastplate that extends along her hips, composed of feather-shaped plates pointing upwards with a large metal flower on the front, leaving the tops of her breasts exposed, as well as her stomach. Her biceps are covered by metal straps and her very large plated gauntlets sport feather-shaped plates at the edges.

Her waist is circled by large, decorated plates reminiscent of feathers that lie on a long skirt. She wears a pair of plated boots which is partially hidden under her skirt, each sporting metal ornaments shaped like wings. She also wears a neck guard made of feather-like plates and a tiara with prominent metal wings. The armor also sports two pairs of large metal wings which adorn her back, composed of metal feathers which get longer and larger at the edges.

Kiba and Koneko blinked at her entrance, surprised, while Issei-

"Whoa, who's the hottie?! She has boobs as big as Rias and Akeno!" Issei said as he stared at the girl with a large perverted grin, temporarily forgetting where they were and why they were here in the first place.

The girl's brown eyes glared at Issei, making him freeze as if death had just come over him. Even the air seemed to have gone completely still just from here mere look. Her eyes shifted over to Damian and softened a little, but didn't lose the authoritative, stern look she had shot at Issei.

"Why is he talking to me?" She asked.

"Just ignore him, Erza." Damian said with a shake of his head, then shot a look at Issei. "And you, stop ogling my Knight."

"She's your Knight?" Kiba blinked while Issei nodded shakily as Erza glared at him, daring him to comment about her body or her revealing armor.

Damian nodded and gestured to her. "Meet Erza Scarlet, daughter of my Queen, Irene Belserion, my second Knight. She wields a magic known as Requip."

"Requip? What's that?" Issei asked, momentarily getting out of his state to ask that question.

"Magic that allows the users to store items in a pocket dimension so they can easily summon it at any time, even during battle, which gives them a high level of flexibility in combat. For Erza, it's weapons and armors that she dons and wields." Damian explained, then gestured to Erza. "This one is known as Heaven's Wheel. And yes, the name irony of the first part of the name was not lost on us."

Erza's attention shifted as she heard Freed groan and turned to face the Exorcist, part of her red hair covering her left eye while the right held a hardened glare at the enemy. "I assume this is a scum serving the Fallen Ones?"

"Yes. He's all yours." Damian said, then waved the others to follow him. "C'mon. Erza will kick his ass and see if she can get some sort of a challenge out of him, though I honestly doubt it."

Erza shot him a smirk. "He was able to graze you."

"he only left a red mark. Don't mistake that for something else." Damian countered with a look at his amused Knight, then made his way towards the alter where a darkened passageway was hidden by a large cross. Damian grabbed said cross and tossed it aside.

Issei looked back as Erza summoned two swords and blocked Freed's attack with ease. "So, is Erza the only one here?"

Damian snorted while descending the steps, followed by the others. "No. Like I said, my servants were ready and prepared. We'll be joined by the others soon, but my Queen is busy with other matters."

"Like what?" Kiba asked curiously.

"Dealing with pests."

Back with Rias and Akeno, they were still facing down Mittelt who scoffed at them.

"Rescue or not, I can't let you go." She informed them with a dark smile. "You're like, totally, the captain of your loser squad and if we take you out they're on a trip to useless town." She spread her wings. "Sorry, but I'm bringing friends to this tea party!"

A magic circle opened behind the two Devil women, drawing their attention, as two more Fallen Angels appeared from it. A man and a woman.

"Good work, Mittelt." Said the female Fallen Angel, a tall and buxom woman with brown eyes and long, navy blue hair that obscured her right eye.

Her attire consisted of a maroon, trenchcoat-like top with a wide collar, a matching miniskirt, and black heeled shoes. The trenchcoat top was open at her chest, giving view to her breasts and cleavage. She also wore a gold necklace around her neck. She appears to wear a white shirt underneath her top, but it can only be seen from the bottom.

"Sad to say we meet again, lady Gremory." Her male companion said. "You should have kept your servant in line."

He was a middle-aged-looking man with short black hair and dark blue eyes. His attire consisted of a pale gray trench coat over a white dress shirt with a matching ascot, black pants and shoes, a pair of black gloves, and a black fedora.

The navy blue haired woman beside him nodded with a smirk on her face "He stuck his nose where it doesn't belong, again"

Akeno grinned at this. "Well, well, the gang is all here."

The two newcomers slowly lowered tot eh ground until they were standing across from Rias and Akeno. The male fallen angel narrowed his eyes at Rias and Akeno as he spoke.

"It seems very clear to us that you intentions here are to abstruct our ritual and that's something we can't allow." He said while his female companion nodded in agreement as they sprouted black feathered angel wings.

"You'll pay for it with your lives!" She declared.

"Well, mind if I cut in on this party?" An unknown female voice, at least to unknown to four, spoke out. Everyone looked at the sound of footsteps to see a figuring emerging from the darkness of the trees, and the sight of her made Rias' eyes widen in surprise.

"Irene?" She asked, surprised to see Damian's Queen, dressed in her witch attire.

Irene Belserion sent Rias a playful tip of her hat. "How lovely to see you again, Rias. A shame we didn't get to talk much in our first meeting. But for now, such pleasantries will have to wait." She turned her gaze to the Fallen Angels, and smirked as she saw how cautious they now seemed to be, no doubt sensing her power. "Now, what do we have here? Three little crows so far from the nest."

"Who the fuck are you?" The blue-haired Fallen Angel glared at her, trying to not show how scared she was from this woman's amount of demonic power.

"I am Irene Belserion, Queen of Damian Mammon-Lucifer's Peerage." Irene said, twirling her staff before pressing it into the ground, a dark smirk on her face as her sharp eyes narrowed on the Fallen Angels. "And I'm here to play."

"Did she say-?! As in the Devil of Death?!" Mittelt's eyes widened.

"Irene Belserion... the legendary Queen of Dragons..." The male Fallen Angel muttered, now more alert than ever.

Irene's smirk widened at their comments, her stance relaxed even though the look in her eyes gave away her intent to fight. "So, let's begin our dance."

"So, is your Knight and Queen the only ones here?" Kiba asked as he, along with issei and Koneko followed Damian down the steps.

"No, the others will be arriving soon." Damian said, then spotted light at the end of the staircase and made his way towards it with the others. they soon came into what they believed to be the basement, filled with numerous priests.

And at the other end was a staircase leading to an alter, where Raynare stood. And hung up on a cross was Asia.

Come on in, Devils, welcome to the party. Though I'm afraid your too late." Rayanre said with a smirk towards the four.

"ASIA!" Issei shouted towards the blonde haired girl.

Asia weakly raised her head to stare at Rias' pawn. "I-Issei… you came..."

"I'm here, hold on!" Issei said as he made to run to her before Kiba grabbed his shoulder.

"No, wait-!" he started before Raynare summoned then threw a Light spear towards them.

Damian grabbed Kiba and Issei, then jumped back with Koneko just as the spear struck the place they had been standing and exploded.

Raynare smirked as the cross that Asia was chained to began to glow, causing Asia to let out a pained scream.

Issei growled as he stood back up, his sacred gear appearing on his arm as he glared at Raynare. "What are you doing to her? You let Asia go right now!"

Damian rolled his eyes while brushing off imaginary dust off his shoulder. "Oh sure, she's going to give Asia up just because you demanded." He then eyed the ritual with a frown. "Hmm, from what I can guess from the sight before me... they want her Sacred Gear."

"What?" Issei looked at him with wide eyes. "What do you mean 'take her Sacred Gear'? What will happen if they do?"

"She'll be seeing God a lot earlier than she wanted." Damian said in a blank tone.

"W-What...?" Issei said with shock on his face before his attention was drawn back to Asia as she let out one last pain filled scream before her body went limp as a green light emerged from her chest.

"And that'd be her scared Gear." Damian said with a frown as Raynare raised a hand towards the two small rings within the light.

"Twilight Healing, at last it's within my hands." Raynare said as she grabbed the Sacred Gear. A gleeful expression came onto her face as she beheld her prize. "Yes, I've been lusting after this power for years! Those miserable hearts are in the palm of my hand! Perfect." She then hugs the light to herself. It envelops into her body, making her throw her head back and moan erotically.

After the Gear sank into her, Raynare started to giggle then she threw her head back in laughter as her body glowed with a green aura.

"I'll be beloved! I'll be unstoppable!" She proclaimed.

"What now?" Koneko asked dryly as the priests drew their Light swords and holy=blessed guns.

Damian smirked. "Backup."

Between them and the group of priests, a white magic circle appeared, surprising everyone except Damian. And then, several figures shot out of the circle, striking the priests with some crying out in pain or surprise as they went flying, crashing into the wall.

When the figures stood still, everyone got a good look at them and saw that it was a group of four women.

The first was Tifa Lockhart, Damian's Rook, ready for a fight as she cracked her knuckles.

The second was a young gorgeous woman of seventeen years, with knee-length silver hair that has bangs swept to the right side, red irises with slit pupils, and a stern expression. For clothing, she wore tight, black leather pants that hugged her legs and hips like a second skin as well as her ass, black combat boots, a black, leather corset top that exposed her cleavage.

Her name was Moka Akashiya, a Vampire and Damian's second Rook.

The third was a beautiful woman in her early twenties. She had 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 other Knight.

And finally, the last girl was just as beautiful as the other three, with fair skin, long ashen-black hair that covers her left eye, that are a bright amber color. For clothing, she wore a dark red, off-the-shoulders v-neck mini dress with yellow designs. There is a blue feather-like accessory on her right hip at the top of an open portion of her dress. The dress ends in an upside-down triangular tail in the back, ending just above the knees.

There is a quarter-circle shaped keyhole on the dress' upper back at the same height as her chest. The sleeves end in a triangle shape, which are wrapped or tied around her middle finger, with the gold designs of the sleeve taking over at the wrists. Her fingernails are painted dark red.

She wears black shorts underneath her dress, as well as a black choker on her neck. She has a gold loop earring with a black gem dangling from it on her right ear. She has dark, glass, high-heeled shoes and a jeweled anklet on her right leg.

This was Cinder Fall, Damian's Bishop.

"Wow! Who are these hotties?!" Issei asked with a perverted grin as he took in the the sight of the beautiful women.

"My Peerage, now stop staring at them like that." Damian said, smacking the back of Issei's head to make him quit with the staring.

Raven turned to her King, raising an eyebrow. "So, get yourself into another mess?"

"I did inform you of the situation. Besides, I figured you guys need to let loose a little." Damian said, then a white magic circle appeared again and Erza came out of it this time. "Nice of you to join us."

"Hmm." Erza smirked, still in her Heaven's Wheel armor and wielding two swords. "That bastard got away after using a smoke grenade."

"Don't worry about him." Damian waved it off. He stepped forward, summoning his sword, Mortem, and held the Holy-Demonic sword at his side. "Now, shall we begin?"

His Peerage grinned before they all rushed to attack...

And that's it for this chapter. Let me know what you think in the reviews, please. By the way, I replaced Mio with Cinder Fall, because a friend pointed out how it would be better.

Harem (So far): Rias Gremory, Akeno Himejima, Raynare, Kuroka, Yasaka, Serafall Leviathan, Katerea Leviathan, Yubelluna, Xuelan, Karlamine, Gabriel, Kiyome Abe, Venelana Gremory, Irene Belserion (Fairy Tail), Erza Scarlet (Fairy Tail), Raven Branwen (RWBY), Cinder Fall (RWBY), Tifa Lockhart (Final Fantasy), Moka Akashiya (Rosario + Vampire)

I'm only doing twenty women for the harem, and I have picked who will be the last, though she won't be in Damian's Peerage, but she is someone who knows him. And unless I get a very good idea for Grayfia Lucifuge, she won't be in the harem. But if I do get a good idea for her from you readers, then I will replace Katerea Leviathan with her.
