Dreagon D. Dragon: Don't worry, I will NOT delete this. I know I've broken my word, but I mean it this time. This story is one of my main focused ones alongside An Avenging Devil, Devil of the League, Lucifer of Mammon, Son of Thor, Son of Death and Marvel's The Bladewolf.

Sen Tobi: Might add her, might not.

It was silent in the Occult Research Clubroom, where Rias and her Peerage did their Devil activities while attending a school named Kuoh Academy. The point of the club was that it was to study the Occult, but that was to just trick the humans while Rias and her Peerage actually did contracts.

Damian sat on one couch, Rias across from him on the other couch with the still confused brown-haired boy, who's name was Issei Hyoudou, sitting in another chair. Damian's opinion about the boy was... low at best. He had seen the lecherous looks he shot Rias, which just annoyed the Devil.

'Damn, Rias has grown into such a beautiful young woman.' Damian thought with a small smile. 'I can just imagine the boys that thirst for her affection.' His smile strained at that thought before he banished such thoughts, especially when his mind went back to when he and Rias last saw each other, the kiss they shared...

He quickly shook that image away and focused on the present.

"So, uh..." Damian looked up, meeting Rias' eyes. "How've you been? You look like you're doing alright for yourself."

"I'd say I have, yes." Rias replied, looking Damian up and down. "Found some new peerage members, one of which you've already met."

Damian hummed, nodding as he cast a quick glance at Issei before refocusing on Rias.

"Family's been alright." she continued. "Though if I said things were perfect... I'd be lying."

Damian frowned and gave her a look, knowing her very well. "Let me guess, THAT man?"

Rias sighed and nodded. "Haven't found any way to get out of it, no matter what. So I figured I'd try building a strong peerage to battle him and earn my freedom."

"What are you talking about?" Issei asked curiously yet with confusion, a small jealous frown as he noticed how close Rias seem to be with this guy.

"None of your business." Damian told him curtly as he gave the Pawn a dismissive glance, then turned his attention back to Rias. "I promised I'd help you out of it and I will."

"Yeah, gain any good peerage members?" Rias asked curiously.

"Yep." Damian nodded with a smirk. "Seven members. I have a Queen, Two Knights, Two Rooks and Two Bishops. No Pawns yet."

"Somebody's been a busy boy then." Rias giggled.

"Tell me about it, been on a lot of adventures these past five years." Damian said with a sigh as he leaned back. "Sadly, couldn't find any potential Pawns for my Peerage, which just sucked, but I made do with what I have and we've trained every single day to become stronger, hell my Queen is gonna have a place on the top 10 strongest Queens in the Underworld. "

Rias let out an impressed whistle. "Guess you did what you said you were going to do. You became stronger and gained powerful servants in the process."

"I'm still confused on what's going on here!" Issei piped up, finally reaching his limit. "Devils exist?!"

Damian gave Rias a look that told her 'Explain this to him because he's starting to get on my nerves.' Rias just rolled her eyes fondly at him before she turned to her Pawn.

"Yes, Devils exist, Issei. As do Angels and Fallen Angels, which is what Yuuma and that man were." Rias explained.

"Yuuma?" Issei gasped. "How do you know Yuuma? Nobody else even remembers her!"

'This Yuuma must be one of the four Fallen Angels.' Damian thought with a frown.

Damian then found himself zoning out a little as Rias explained exactly why 'Yuuma' had gone after Issei, something to do with the kid having a Sacred Gear. Sounded like she'd led the kid on a date and then killed him at the end of it, at which point Rias had saved his life by reincarnating him as her Pawn.

The kid hadn't made much of a good first impression on Damian, but that didn't stop him from feeling a bit sorry for him. Your presumably-first girlfriend stabbing you in the heart... probably literally? That couldn't be good.

Once Rias finished explaining everything to Issei, and gave him time to come to grips with the fact his 'girlfriend' killed him, Rias turned her attention back to Damian and frowned. "No offence, Damian, but why are you in Kuoh? I mean, did you know I was here?"

"No." Damian shook his head. "If I had, i would've been here already to see you. I was actually up in my nightclub in Tokyo, Seventh Heaven."

"Oh, I've heard of that place!" Rias said with a smile. "Said to be one of the biggest clubs in the world, earning a lot of money from it's various branches around the world. So you own it?"

"Well, my Rook does but my family and I helped get her the money she needed to make it bigger than it used to be. In five years, Seventh Heaven went from a small bar in some forgotten town to a nightclub everyone knows about. You should visit."

"I just might if I get to see you more." Rias said with a flirtatious wink, causing Damian to smile at her before he reached over and grabbed her hand.

"I missed you." He said softly.

"I kissed you too." She said, equally softly. "Now, I have to ask since this is my territory... are you responsible for the dead priest that have shown up? Human authorities are baffled and think some kind of bear mauled them with how they've been slaughtered. My Familiar investigated and found traces of demonic energy, and then I find you. Can't be a coincidence."

Damian chuckled. "Still as smart as you are beautiful, my dear. Yes, I am responsible for killing the priests. I have been... hired to track down a group of rogue Fallen Angels that are hidden in this town, to bring them back either dead or alive to their boss, Azazel."

"I see..." Rias replied. "You've been working for the Fallen Angels?"

"Not them specifically." Damian replied. "Peerage and I've been doing odd-jobs for anyone around the supernatural world who needs them doing. Get paid pretty well for it, too."

"Right." Rias nodded. "I'll have to tell Sona about this. Yes, Sona's here too." she added, as Damian raised an eyebrow. "She and I kind of co-oversee this territory. But getting back to the point, I can't imagine you'll need help with this whole Fallen Angel situation, if you've gotten as strong as you say you have."

"Yeah. I'm good, thanks." Damian replied. "I doubt I'll be here long. I'll just nab the crows, either bring them back to their boss or kill them if they resist, and then I'll be out of your hair."

Rias frowned at the thought of him leaving again, but she remembered he was only up in Tokyo, and she could easily teleport to his location to see him, maybe convince him to attend Kuoh Academy with her. Plus... they'd have to talk about their relationship, especially since they shared several kisses the last time they met.

But... that could wait until they were in a more private setting.

"Alright." Rias replied. "I'm alright with letting you handle the Fallen Angels, if that's what you want. While you're here, though, would you like to meet the rest of my peerage? And... can I meet yours?"

"I'm alright with meeting your peerage, if that's what you want." Damian replied. "As for meeting mine, some of them are on assignments right now, and I'd prefer you meet them all at once so I didn't have to arrange multiple meetings, you know?"

"Understandable." Rias nodded. "I'll call my peerage now."

Creating a magic communication call, Rias quickly summoned her Peerage and the Gremory magic circle appeared at the doorway of the club before Akeno, Koneko and a blonde-haired boy were revealed.

"Damian?!" Akeno's eyes widened in shock at seeing him again after five years and Damian's eyes widened, seeing Akeno had also grown quite well since he last saw her.

"What's up, Akeno?" Damian greeted, before letting out an "oof!" as Akeno rushed over, practically diving on him and grabbing him in a tight hug.

"I missed you so much~!" Akeno cried. "It's been too long...!"

"I know, I know." Damian replied, managing to push himself up from his position below Akeno, though her arms were still around him. "But I'm here, now."

Rias smiled, though her eye twitched as she saw Akeno practically straddle Damian while hugging him. She rolled her eyes before saying sternly. "Akeno."

Akeno looked at her with a smirk and a sweet giggle. "Oh Rias, don't be jealous that I'm merely reuniting with one of my oldest friends."

"Lucky bastard." Issei muttered with jealousy as he glared at Damian for having a babe like Akeno straddling him.

"Uhh, Akeno?" Damian asked, from below. "Maybe those in Rias' peerage who've been introduced to me would rather they met me without you straddling me?"

"Fine..." Akeno pouted, shifting herself off of Damian, but keeping her place right beside him. Rias cleared her throat.

"Alright, then." she remarked. "Koneko, Kiba, this is the childhood friend of mine that I've told you so much about, Damian Mammon-Lucifer. Damian, this is Koneko, my Rook, and Kiba, my Knight."

Damian nodded to the pair of them. Koneko nodded back, with Kiba inclining his head as well.

"Is this all of them?" Damian asked curiously.

Rias shook her head. "No, I have a Bishop but he's... sealed away."

Damian frowned. "Why?"

"I'll tell you later." Rias replied. "When he's ready to be unsealed."

"Alright, fine." Damian shrugged. "And then there's Issei, but we've met already, as you said." he added, jerking his head in Issei's direction.

Rias nodded.

"So... how long do you think you'll be in town?" She asked.

"Until the Fallen Angels are dealt with and I get paid." Damian admitted honestly.

"Well, before you leave after the job is complete, or even before you go to look for them, can you and I... talk?" Rias asked, giving him a meaningful look. "About us?"

Damian looked surprised but he nodded, knowing it would have to be addressed, and both would rather it be done sooner than later, while nothing distracted them.

"Sure." Damian replied. "Would you rather do it here, or somewhere more private?"

"Definitely private." Rias remarked, instantly. "Everyone, you're dismissed for the night. I'll see you tomorrow."

Akeno, Koneko and Kiba nodded, all making their way out of the room, while Issei was a little more reluctant to go.

"Prez?" he asked, looking between her and Damian. "I-"

"Dismissed." Rias cut across him, fixing Issei with what looked like a more grown-up version of the look Damian had seen so many times when he and Rias were younger. "I'll see you. Tomorrow."

Issei seemed to finally get the point, and left the room as well, but not glaring jealously at Damian for a second or two once he shut the door.

"Your Pawn's quite infatuated with you." Damian said after a moment of silence.

"As are all boys at this school, even some girls." Rias said with a slight grin before she got up and walked over to sit next to Damian, who scooted over a little to give her room, but there was barely a gap of space between them as their clothing and shoulders brushed against each other.

"So..." Damian said.

"So..." Rias chuckled, both clearly trying to find the right words to say. "I'm glad you're back in my life, Damian. It's been... lonely without you. Sometimes I wake up at night, sweating and terrified."

"Nightmares?" Damian asked, getting a nod from her.

"Of Riser taking me away, making me some... glorified prize for him to breed with. He's only wanting me for my last name and family prestige, unlike you." Rias said softly, looking at him. "You didn't have to go as far as you have just to try and free me from-"

"I promised I would." Damian said firmly as he placed his hand on hers, which she turned over so she could grip it. "Five years ago, you wanted me to promise that I would come back and take you from him, and I fucking intend to. If I have to... I'll challenge him either for your freedom or your hand in marriage."

Rias looked back at Damian, slightly stunned by what he'd said for a couple of seconds, before she wrapped her arms around him in a hug similar to Akeno's.

"Thanks, Damian." Rias whispered, resting her head on his shoulder as she hugged him. "I... really needed to hear that."

"Hey, no problem... Tomato-Hair." Damian replied.

Rias rolled her eyes, but was too comfortable hugging Damian to really do anything about him calling her that old nickname. At least no-one else was around to hear him say it.

She pulled away a fraction and leaned her forehead against his, staring into his hazel eyes as he stared into those gorgeous blue-green eyes of hers. They leaned forward and pressed their lips together, having their first kiss in five years. Rias moaned softly as Damian's hands ran up the sides of her body, one staying on her waist while the other got tangled in her hair. Rias' hands roamed Damian's body before she wrapped them around his neck to pull him closer.

Slowly, their kiss grew more heated and passionate as Rias pulled herself down, taking Damian with her so he was on top of her. Their tongues battled for dominance as Rias lifted a leg to wrap around his waist, causing him to place a hand on her thigh and roam his hand up and down her creamy flesh, then gripped her tight as he continued to makeout with her... until he felt her hands trying to fish into his trousers for a certain part of his body.

"Wait, wait." Damian pulled away, panting. "We-We can't do this."

"It's okay, I want to." Rias said softly as she wrapped both of her legs around his waist.

"No." Damian said with a little firmness in her voice. "I'd rather... I'd rather your first time be special, Rias. When you are free of your marriage with that damn bastard, when I can make you mine."

"Alright..." Rias pouted, shifting herself off of Damian and sitting back down on the couch beside him. "Fine. You better make it worth it, though. Agreed?"

"Agreed." Damian nodded, wrapping an arm around Rias and allowing her to rest her body against his again.

"You know, you don't have to go back to Tokyo straight after you've done your job." Rias said, causing Damian to look at her. "You could apply for a place here, at Kuoh Academy, you and your Peerage, if you want."

"Hmm. We'll see, my dear." Damian said and kissed the top of her forehead. "We'll see..."


And that's it for this chapter everyone. I hope you liked the reunion between Damian and Rias, and them catching up, as well as them wanting to continue their secret relationship, well it's more of those cliché affairs. Rias is a woman engaged to another man, and is in an affair with another... sounds like something out of one of those romantic movies or TV shows. But, Damian and Rias have been in love with each other for a long time.
