In the warmth of a summer night, in a newly cut clearing in an ancient forest, the heat radiated from the ground as the moon shone clearly on the first floor that had not been touched by moonlight In many centres. At the centre of the clearing was a significant barrier made of galvanised steel fences, which enclosed the sight of extensive digging. The area was an archaeological dig site, which had uncovered the ruins of large stone foundations and a partially exposed stone floor with semi-preserved wooden structures embedded into the ground. There were numerous marble statues of men and women, which the passage of time had taken its toll on, with missing features and chipped stonework.

On the grounds of the sight, there were two small industrial excavators. Based on the number of shovels, spades and other such tools, a small group of around 10 archaeologists and volunteers worked on excavating the sight. Due to this, the purpose and origin of the structure had yet to be determined.

In the distance, on the outside of the clearing, a giant maple tree stood proud amongst the forest, its silhouette breaking the uniformity of the smaller trees. Four people stood on one of the branches close to the top of the mighty tree, their figures masked by the darkness.

"How long do you think it will be before they arrive?" a deep-voiced man asked, his annoyance growing as he looked into the skyline and watched the distinctive glow of artificial lights radiating from the buildings and removing the stars from the night sky that was above the city.

"Be patient. Do not let your love of battle cloud your judgement and ruin our plan." another voice stated, placing a hand on the annoyed compatriot. This voice was not as low and rough as their ally, but it was clear from their tone that it was a man, and unlike his ally, he seemed to be more calculating and patient.

"Remember, what we require is of no use without their involvement. Besides, the magical energies emanating from the sight will come to their attention soon enough." The voice of a young girl cut through the silence of the night; it had surprising warmth despite the implications of what she had said.

"And once we have dealt with them. I will be unstoppable," the authoritative voice said, raising his hand to his face and clenching it into a fist, his knuckles cracking. His voice was proud and confident to a level that bordered on arrogance.

24 hours later

The Occult research club at Kuoh Academy and the peerage of Rias Gremory were hard at work, performing their duties with the usual amount of lewd banter and teasing befitting a peerage that contained Issei Hyodudo. I was busy filing away a dense pile of pact contracts. All the while, a particular fallen angel had decided to use this time to mess with Issei.

"Issei, do you like this look?" Akeno purred.

"Cut it out..." Issei groaned, only to stop mid-sentence when he realised the sight above him. He was kneeling in front of a filing cabinet dealing with the contracts beginning with the letter D. Akeno, standing over him, had decided to bend her knees ever so slightly and lean over Issei. She was still in her school uniform, which, to Isseis's perverse mind, only made the scene even more distracting for all the wrong reasons.

"Come on, Issei, you hurting my feelings...besides, I thought you liked boobs, haha," Akeno pouted as she puffed out her chest further, causing one of the buttons on her shirt to ping open to reveal a small amount of her flawless skin

"Uhhhhh... no, no, no, Ive got to remain focused..." Issei stuttered, shaking his head to try and clear out the dirty thoughts, only to internally monologue to himself

"Besides, if I don't get this done, Rias will be mad, and I don't want to let her down; this is super important, but...Akenos boobs are just..."

"How about this..." Akeno sexily whispered as she unbuttoned her shirt slowly and sensually, causing Issei's mouth to slowly drop in time with each button.

"But Akeno, Rias will see us and get mad. Besides, we're supposed to be working..." Issei waved his head back and forth from Akeno to the entrance to the filing room, his voice yelping in worry, which only brought a sexy laugh and smirk from Akeno.

"Hehe, the thought of Rias catching us makes my heart race, like we are forbidden lovers who must never meet...besides, the longer I hold back, the hotter I get." Akeno's hands snaked up and down herself, moving every inch of her body, causing Issei to gasp in awe at the sight, which became far lewder when Akeno, sensing the opportunity, grabbed Issei's right hand by the wrist and pulled towards her chest,

"Oh my", Issei thought as he felt his body turn to jelly as his hand moved ever closer to Akeno's chest. Unbeknownst to Issei or Akeno, the door to the storage room had not been closed properly, allowing a certain crimson-haired devil to catch the last act, which caused her blood to boil.

"I'm literally millimetres away from boobie magic..." Issei thought with child-like glee, only to be instantly snapped out of this moment by a very familiar voice.

"Issei. "Rias glared, her voice as cold as ice, as she stood there, arms crossed over her ample bosom,

"AHHHHHH!" Issei cried in fear, causing Akeno to let go of his hand.

"Hello, Rias," Akeno said, acting as if nothing had happened by waving her hand lightly to her friend, who did not reciprocate the wave and instead slowly walked towards Issei, not saying a word.

"Rias...gulp," Issei said in a pleading whisper; he had seen that glare before and knew what it meant.

"I was just helping Issei with his filing; he was having issues with the D rack..." Akeno smiled innocently, talking so casually that it seemed she was oblivious to what she had been doing moments before.

"Sure. However, based on what I can observe, the rack Issei was having issues with was not a D." Rias looked Akeno up and down around her chest area.

"Oh...would you believe it had opened by accident." Akeno acted in shock at the sight before her, but she knew she was caught

"No."

"I can explain, Rias! OUCH!" Issei put his hands up innocently as if he had just been caught red-handed stealing. Still, his attempt to submit was met by a swift grab of his ear as he was pulled away from Akeno, screaming from the pain as he was dragged out of the room.

"Issei. I love you a great deal, and I respect your ambition to become the harem king, but please, keep your urges in check, especially when we have important work …" Rias explained, disappointed in her voice, with no sign of struggling to drag Issei across the floor.

"But it wasn't my fault!" Issei pleaded even though he knew he was partly responsible for what had happened.

"Besides, if you really wanted a sensual work experience...you only had to ask?" Ria's proclamation turned to a quiet whisper as she leaned next to Issei's ear, causing Issei to mutter quickly and in shock.

"Wait, what?"

"Did I hear that right?" Issei's thought brought Ddraig to fold,

"Your ears do not deceive you."

"I'm serious, Issei... you mean a great deal to me, and I would do anything to make you happy..." Rias pulled back to look at Issei, her eyes meeting Isseis, which locked the pair in a close gaze.

"And I'd do the same for you, Rias," Issei replied with a kind smile backed by kind eyes, which made Rias smile back softly.

"I wouldn't expect anything less, Issei," Rias said sweetly. The pair had unconsciously gotten physically closer through this short exchange. They were only a few inches away from making physical contact, which Issei clicked on when he focused on Rias's eyes, which were such a stunning shade of blue that Issei felt was causing him to slowly melt in her comforting gaze.

"I should lean in and kiss her..." Issei thought as he leaned slowly toward Rias, who followed suit. Just as their lips were about to touch, the door to the room swung open, revealing the rest of the peerage, all of whom had a range of expressions, from wrathful to jealous.

"Is this some R-rated action, and if so, why were none of us invited?" Xenovia stated as she entered the room, resulting in Rias blushing and Issei floundering

"It's not what it looks like!" Issei fired back, looking to Rias to back him up, only to find she had hidden her face in her hands out of sheer embarrassment.

"I almost missed out again! Well, no more!" Asia proclaimed in her high-pitched voice as she rushed over to Issei and tackled him to the ground

"Come on, Asia...HEY!" Issei cried as Asia started unbuttoning his shirt, then her own, revealing a pink bra. Asia's own ample Bussom, while not as large or as soft as Rias and Akeno's, were still perky and bouncy, which caused Issei's nose to bleed.

It was this act of shear boldness from the former nun that caused Rias to break from her embarrassed state, with the sight of Asia attempting to unhook her bra,

"Asia!" Rias yelled as Akeno walked over to her friend.

"Well, she's becoming bolder with each passing day, hehe", Akeno chuckled, raising her hand to her lips as she walked to stand behind Asia.

"What are you doing, Asia!" Rias roared, her jealousy growing as Asia straddled Issei, and based on this, she was not going to move.

"I don't want to be left behind! Besides... I don't have all the advantages of the other girls..." Asia yelped, but it turned into a low mumble as she tapped her chest, causing a slight jiggle that caused Issei to blush even more. Rias noticed this and gave Issei a quick glare, causing his blush to fade instantly.

"You have your own advantages, Asia," Issiei stated softly, wiping the blood from his nose as he said this.

"I do?" Asia said, confused by what Issei meant.

"Yeah! You are innocent, sweet and one of the kindest people I know. You'd do anything to help someone in need. You always look for the good in everyone." As Issei said this, he buttoned up Asia's shirt, which, given the closeness and the kindness of Issei's words, Asia began to blush.

"Really?" Asia's voice perked up upon hearing Issei's answer.

"Yeah, really. I wasn't doing anything Asia, plus everyone is watching..." Issei said with a smile which changed to an embarrassed mumble as he looked around the room, only for Koneko to state in her monotone voice

"I bet that gets your motor running, Issei."

No, it doesn't, and...uh, shut up!" Issei yelped as he failed to fire back an insult, making him even more flustered, and Konkeo stuck her tongue out. Just as this was about devolving into an argument, an all too familiar voice joined in.

"Hey kids...what have I missed...or is the good stuff just about to start?"

"Azazel, what are you doing here?" The room asked as Azazel walked in, his hands in his pockets

"Well, given the time, I'd usually be in my flat enjoying a bottle of fine scotch and designing a new artificial boosted gear to try out. However, my usual night abruptly stopped when the device I created to locate particular magical signatures picked up one." Azazel pulled the device from his pocket; it was similar in design to a Giger counter.

"Any ideas as to what could be creating the signature?" Rias asked, her curiosity growing.

"I have no idea. The signal, while powerful, seems to be dampened, so I decided to examine the location from afar, and it turns out to be the site of an archaeological dig." Using a spell, Azazel produced an image of the site, showing the structure's remains to the peerage.

"Oh, sounds like some Indiana Jones shit." Issei joked, getting a few chuckles.

"You're not wrong...wait," Xenovia replied to Issei's comment, only to stop when she tapped the magical projection to zoom it in and noticed something in the picture.

"What is it, Xenovia?" Asia asked, looking back and forth between the picture and the former church member.

"The structure is in the same style as an early Christian church. But that can't be?"

"Wait, I'm lost; what's wrong? It's just a church." Issei stated, confused by Xenovia's shocked reaction, which Xenovia swiftly replied to in a shocked and concerned tone.

"The reason it's odd, Issei, is that a church building of this design would not have existed in Japan. The church did not have access to these lands until the Portuguese arrived in the 16th century, and by then, the design of churches had changed significantly...This church, if it is real, predates the church's involvement in Japan by a thousand years."

With this statement, Rias quickly considered an explanation for the power output from the church ruins.

"And with a power output like this emanating from such an old sight, we may have a powerful relic which must be removed before it falls into the wrong hands", Rias added; she had done her reading on the relics of the church and knew that the early church had been influential in the creation and protection of powerful relics despite their small size at that time.

So Rias, are you in favour of checking the sight out." Azazel asked, noticing the flicker of curiosity in Rias's eyes

"Yes."

"Alright, everyone, get your things. We're going on a treasure hunt!" Azaezel proclaimed with a cheeky grin as the group gathered their things and readied themselves for the task ahead. At the same time, Azaezel, as a mentor and guardian, summoned a bottle of scotch and whisky glass and sat in Rias's chair, watching the group prepare, not caring for the scowl directed towards him by Rias.

Hey everyone
