I do not own Highschool DxD nor do I own Diablo. All rights respectively go to Ichiei Ishibumi, the series' creator, and Blizzard Entertainment, the company who made Diablo.

A red glow of light emerges from the floor, showcasing some sort of Devil seal. From the seal emerged two familiar figures. The Great Ladies of Kuoh, Rias Gremory and Akeno Himejima, surveyed the surrounding area and see how damaged it has become.

It looked bad but not enough for it to be completely renovated. Just fix a few patches here and there and the park will still look as it was before.

"Buchou," Akeno called out. "Your orders?"

"The Fallen Angels have fled for now. Clean up the area," Rias commanded.

"On it," Akeno went to work restoring the park as is.

Rias walked around and saw the first boy, Issei Hyoudou, already dead. She noticed the wound looked to be from an assassination, not of the battle. With that in mind, she sought to look for the one man who had done such a thing. And luckily for her, that man was not far.

Seeing the disgusted corpse of the Fallen Angel beside the dead body of Aidan, Rias knelt down and took notice of his injuries. But what surprised him most was the weapon he held in his hand. A hand-held crossbow.

"To think he was able to fight off a Fallen Angel," Rias muttered to herself as she looks at the head of Aidan. "Aidan Kain… just what are you?"

In Rias' mind, today's events have been most troublesome. With the secret part of the library now known to this one student of Kuoh Academy, and of the books he had read, Rias became curious of this human. His mind must have contained vast sums of knowledge, which may be useful for her peerage. But what she also wanted was his combat prowess.

And she knew what to do.

"Buchou," Akeno called out. "I have finished cleaning up the area."

"Bring the body of the other boy here," Rias said as Akeno does just that with Issei's.

"Ara ara," Akeno said with a hand to her cheek. "You plan to bring them both into your peerage?"

"There is such magical potential in both of them, especially the new transfer student," Rias said while looking at Aidan. "Besides I want to know why he was researching Devil Mythology in the first place."

"Or perhaps you want to make him become your new favorite? Ufufufu…" Akeno sadistically teased her best friend.

Rias could only smile. "Now is not the time for such things yet, Akeno. However, the Evil Pieces will decide whom they will choose. We'll just have to see where we go from there."

With that Rias begins some sort of chanting, the red seal underneath the two dead boys' bodies.

Death took them briefly, only for a Devil to bring only one of them back into the fold.

NEXT MORNING…

Aidan soon wakes up as the morning rays shine into his room. He found himself with that familiar ceiling of his bedroom staring back at him. Somehow, he was in the confines of his comfortable bed, trying to understand just what went on.

Was it all a dream? It couldn't have been one though. He had just fought a Fallen Angel and defeated him, albeit at the cost of his own life. It was strange though. He didn't have any nightmares left, at least for now.

Aidan sits up half naked with only his boxer briefs on. He then looks down to see his wounds all healed up. But he was certain that he had died. Confusion was all that lingered in his mind, but he decided to put it away for now and return to the warmness of his bed.

Speaking of warmness though, Aidan closes his eyes and wraps his right arm over a big, soft, and warm pillow and laid there.

Only that it was no pillow.

Opening his eyes, Aidan sees his arm around a person with a curvy body. Red locks of hair stuck out from her head, smelling like strawberries for some odd reason. Unfolding his blankets via the corner, Aidan sees the sleeping and naked form of Rias Gremory.

Aidan's eyes were glued onto her peaceful sleeping form. Her beauty captivated him though, like Inarius was to Lilith. Though she was a devil and he was a human, she did not seem to have one trace of demonic feature on her, even if she were disguised.

Taking a big risk, he brings one lock of her hair that was in front of her behind her ear. This however wakes her up as she stares at Aidan, along with his upper muscular body shown. She could not help but blush at the sight of it.

"Oh, good morning," Rias said casually in her beautiful voice.

"I must admit, I did not expect to see you here. In my bed of all places," Aidan said with a small smile. Rias however was surprised.

"I did not expect you to not be surprised that I am naked," Rias replied as she yawns and stretches her arms up. "Which means you must have slept with other women in your life?"

"I haven't actually," Aidan said as he brings his legs over the side of the bed. Rias was surprised once again. A handsome fellow like Aidan with a handsome body never having slept with any girls astounded her. "You're my first. And yet, you seem to be calm about all this."

Rias giggles. "There is no reason for hostility, Aidan. I'm not going to hurt you."

"You don't seem like the type," Aidan said. "Then again, who's to say you don't bite?"

Rias giggles as she sits up and looks at Aidan's back. The man was looking at himself in the mirror to check his body. Rias was all but enraptured by the body, feeling something of an urge inside of her to touch it.

"I also see that my wounds are healed," Aidan said. "Though it still does not explain why we are both naked."

"I had to remove your torn clothing in order to heal you," Rias explained. "You were in critical condition, but thankfully you don't die that easily. So I spend the whole night healing you by embracing you while we were naked. I was able to do it because we're from the same peerage."

"Peerage?" asked Aidan.

"A group consisting of people," Rias explained as Aidan dresses himself. "From this moment forth, you are indebted to me." Rias points at Aidan calmly, making Aidan see it and accept.

When Rias puts her hand down though, a small saddened expression emerges on her face.

"I'm sorry I wasn't able to come to your side when you needed help," She said as she got up and walked to Aidan. She presses her hand on his bare chest, feeling the strong pectoral muscles and tracing a cut he received. "You've had to fight alone one time and died. Had I come to you, I—"

But in a surprising move to her, Aidan took her hand gently.

"Don't be sorry," Aidan said calmly. "You could never have known what would happen. And the attacker is already dead. Why don't you stay for breakfast?"

Rias looked at him with watery eyes before blinking and them clean and nodded. As both she and Aidan get dressed, Aidan tries to keep his blush in place. He is never usually flustered when it comes to girls naked, but Rias' body was very, very beautiful. It was no wonder everyone worshipped her, and she was deemed one of the Two Great Ladies of Kuoh.

"Aidan, can you help me with my bra?" asked Rias as she was trying to attack the back.

"Of course," Aidan said as he helped her from behind. Rias was once again surprised by his tone. It was gentle and soothing, and he didn't seem to be embarrassed one bit by her naked. This made her even more interested in him.

Once Aidan was finished, Rias leaned back into his chest as Aidan caught her. She could feel his big hands on her shoulders, like she felt safe and secure. Of all the male students in Kuoh Academy, she felt like he was something more, like how even the sexiest of girls can fall for a handsome guy like him.

"Rias," Aidan spoke up. "Why are you doing all this? And who are you? You managed to rescue me from certain death, heal my wounds and sleep with me naked. You clearly are of no threat to me nor my uncle. But why are you doing this?"

The redhead turns around and places a hand on his cheek. "I understand your reason for asking, but I promise that I will tell you everything soon. So let me start off with this; my name is Rias Gremory. I am a Devil of the Gremory Family. As of last night, I became your master. It is good to meet you, Aidan Kain."

Aidan, understanding the situation at least somewhat, replied, "I am your servant, Rias Gremory."

Knock! Knock! Knock!

Three knocks on Aidan's door interrupted the two as they let go immediately.

"Aidan, are you alright? It's time for school," The elderly voice of Deckard Kain spoke through the door.

"I'm up, Uncle," Aidan called out. "I'll be down in a minute. Just let me finish getting changed." Aidan then turns to Rias as soon as he puts his shirt on. "I'll go make breakfast for all of us. And don't worry about my uncle. He is a nice person."

Aidan soon exits the door with his uniform on. Rias looked on with wide eyes before shrugging to herself and returning back to dressing herself. But before she could put on her socks, Rias saw something on Aidan's desk in front of her.

A large necklace lied on Aidan's desk, connected by a black thick string. It was a large vertical infinity sign whose end piece at the bottom was missing. In the top circle was a golden disk encased in it.

Rias picks it up and stares curiously at it. She has seen this symbol before. In a bedtime story that she read long ago but she could not make out what it was. However, using her demonic powers for a bit, she could feel that the necklace contains some sort of enchantment but something foreign to her. It was not Devil, Angel, nor Fallen Angel. It was something… more.

Looking at the golden disk embedded in it, Rias could see her reflection. All she was looking at was just some sort o amulet, yet a part of her felt there was something intriguing about it.

And yet, for all of Rias' curiosity, she could not help but feel a tinge worth of dread creep upon her. Like something big will happen soon. What it was she does not know.

And yet, a dark cloud seemed to be over the horizon, heading on its way here.

Aidan was busy making an English breakfast to notice the fact that he wore only a tank top. But while cooking, he had to contend with what he had just seen this morning.

Rias Gremory, one of the Two Great Ladies of Kuoh, a Devil of the Gremory Clan, had slept with him.

Aidan did not count on the fact that she came to his aid and resurrected him as her servant. However, if this would help his uncle's works, then perhaps it is a good thing. But the question is, how will he be able to tell Uncle Deckard about all of what has transpired?

"Oh, Aidan," A familiar voice called out. "You are up making breakfast already. In your school uniform."

Aidan turned to see Deckard Kain in his teacher outfit, coming down from the hallway with his briefcase. There was nothing too out of the ordinary of the briefcase, except for the fact that a few of the papers in it had some personal work of Deckard's.

"I woke up late, Uncle," Aidan said. "So, I thought I'd cook up a quick English breakfast."

"That does not explain why there are three plates," Deckard noted, pointing to Rias'.

Not one to be a liar, Aidan simply explained, "We have a visitor today."

"I think I will show myself, but thank you. Good morning, Professor Kain," Rias showed herself by the stairs, surprising both Aidan and Deckard, fully dressed in her uniform and with Aidan's necklace in her hands.

"Oh it's you, " Deckard exclaimed. "Good morning to you as well, Rias Gremory."

"You two know each other?" asked Aidan with an eyebrow raised in surprise.

"I have her and the other one, Akeno Himejima, in my class, if that is what you are wondering," Deckard said.

"Your uncle is well-versed in his department of religious studies," Rias said. "He challenges us to think critically and his teaching methods are easy to follow."

"Is that so?" asked Aidan.

"So what brings you to our home this morning, my dear?" asked Deckard kindly.

"I assure you I didn't do anything bad to your niece, professor," Rias said as she takes her seat. "You see, I was out late last night doing something important and was on my way home. But it was really dark, and I didn't feel safe, as my home was about half a mile away from the school. So, I called for Aidan and asked him if I could spend the night at your home. He was generous enough to come get me himself and bring me here."

Deckard sighed happily. "Ahh… It is wonderful to hear that you are safe and sound, my dear. I will be sure to let your parents know just to ease their worries."

"Thank you, Professor," Rias thanks before Aidan serves her breakfast, along with his and Uncle Deckard's.

Once breakfast was over, Deckard had to return to his office to finish a few things and urged Aidan and Rias to walk on without him for he can catch up. Aidan puts his shoes on by the door.

"Ready to go?" asked Aidan.

"Wait, Aidan," Rias calls out to Aidan before she holds up his necklace. "You left this in your room. Let me put it on you before we depart."

"Of course," Aidan said as Rias comes forward and wraps the necklace around him. The two were up close as Aidan could feel Rias' boobs on him. It gave him a small blush, but he composed himself well.

Once Rias puts the necklace back on Aidan, they separate before the two head out the door.

Both Aidan and Rias were now on their way to school, walking together side by side. Rias carried her schoolbag with both hands, while Aidan had his in his right hand by the side.

"Your uncle is a very nice person," Rias complimented.

"He was always a kind scholar. Wanting to help people in need. I am surprised though he took a liking to you given of your nature," Aidan smirked a bit, making Rias giggle.

She then looked curiously at Aidan and suddenly asked, "So where are your parents?"

"I never knew them."

Rias stopped in her tracks and looked at Aidan, who seemed unconcerned about the topic.

"What do you mean?" asked Rias.

"Let me rephrase that. When I was a baby, I was left alone in an alleyway abandoned. That is until Uncle Deckard found me. He has raised me ever since."

"So you only grew up with your uncle?" asked Rias. "I am so sorry to hear that."

"No, no," Aidan reassured gently. "It's alright. You didn't know and were merely curious."

The two continued their walk together.

"My uncle and I have basically traveled all over the world," Aidan explained of his childhood. "We've been to the ancient Mayan ruins of South America, the temples in China, the papal tombs in Italy, and even the primitive tribes of Africa."

"What have you been doing in those places?" asked Rias.

"My uncle isn't just a religious studies professor. He is also an archaeologist. Studying ancient civilizations and uncovering rare and unique artifacts of old."

"Oh? And are you interested in taking up your uncle's work?"

"To be honest, I am," Aidan said, making Rias surprised yet more intrigued at the man. "Since Uncle Deckard is the only family I have in my life, it makes sense I take up his work."

"Well, I'm glad you still have a family around to make you happy," Rias said with a smile as the two continued walking in silence.

As the two enter the school yard, everyone stopped walking to see the two of them together. Almost all of the boys looked at Aidan in anger for walking with Rias, to which he didn't seem to care one bit. Some of the girls seemed to admire the idea of the transfer student and one of the Great Ladies of Kuoh walking together while some felt jealous because of Rias walking with a handsome man like Aidan.

Entering the main school building, Rias stopped and turn to Aidan. "I'll see you after school, Aidan."

"Where at exactly?" asked Aidan.

"The old schoolhouse. Head there and I and the others will be waiting."

"Others?" asked Aidan.

"You'll see," Rias smiled. "Bye for now, Aidan." Rias gave him a wave and walked away, leaving Aidan all alone before he went his own way.

As Rias walks up the stairs to her classroom, her thoughts drifted towards Aidan and the necklace he wore. Despite his appearance that may seemed cold and distant to the naked eye, Aidan was kind, and sweet, just like Professor Kain. He had a lot of unknown potential in him, something Rias wanted to see.

But the necklace, that symbol. Rias had seen it before. It was in one of the books of Devil Mythology. Since Aidan's infiltration into the secret library, she had been reading the Devil Mythology books alongside Sona, trying to figure out what Aidan's intentions were.

But so far she came up with nothing until she found Aidan's necklace.

"You seem troubled, Rias," Sona Sitri spoke up, who was leaning on a pillar on the second floor.

"Just processing is all," Rias said. "Do you still have one of those books?"

Sona shook her head. "No, I put them away in the library. Why?"

"Earlier today, I saw a necklace of his that looked like on one of the books. The Horadrim I think the title was. In that moment when I touched it, I felt some sort of fainting echo of power. It wasn't Angel, Devil, or even Fallen Angel. Either it was just a good luck charm or there was something more to it."

"I've never seen you take on anyone so impulsively," Sona commented. "What makes him so special in your eyes?"

"Honestly, I don't know," Rias said truthfully. "When I first spotted him, I saw someone who stood out from the others. Him breaking into the library only confirmed it for me. But when I talked to him, he was like someone who saw me as an equal. I found myself enjoying it."

Rias then turned around and looked upward with her back against the railing.

"But if I were to be completely honest with you, I would have to say that it was when I was watching him fight with that Fallen Angel." Rias could remember that night when she was sleeping in the old schoolhouse that she felt a presence, ran outside, and saw a fight between Aidan and Dohnaseek, hiding behind a tree. "As I watched him fight, I could tell he has had experience. He had managed to kill a Fallen Angel, a powerful one at that. One that no human would ordinarily be a match for. He knew how to handle it despite being wounded."

Rias hugs her elbows close to her when she remembered Aidan's injuries and drinking his healing potions.

"His fighting style was not like anything I had ever seen before. And when he was on the verge of death, he had managed to kill the Fallen Angel. Then he spoke of words I never heard of."

Rias could recount Aidan's last words to Dohnaseek.

'May Terror spit on your grave!'

Those words to Rias only backed up her theory that Aidan knows something she does not. And if so, then what was it he knows?

"When I saw him dying, lying in his own pool of blood, I wanted to give him a second chance. I saw potential in him. And he and Professor Kain may be holding something I am curious of. The breaking into the library and the research into Devil Mythology proves it, but what it is they are looking for, I do not know."

Sona looked at her friend with a stunned expression. She never heard Rias go deep into a topic about the new transfer student. She thinks partially that her best friend had lost her mind. Was Aidan really that big of a deal? A transfer student out of nowhere who had managed to defeat a Fallen Angel?

"I see," Sona said, her mind thinking about the young man.

When the bell rang for the end of school, Aidan stretches his legs for a bit. Today had been a long day but he was not too tired.

'I wonder how Uncle is doing with his new life as a professor here. Maybe I should go check on him in his new office before I head over to the schoolhouse.'

Packing up his schoolwork, Aidan carries his school briefcase before three young male students stopped him and stood in his way.

"Stop right there, Kain!" said the first one named Matsuda, who was shaven bald with big egg ears. "We got questions for you, you bastard." Aidan was unthreatened by their demeanor.

"About a few hours ago," said the other one named Motohama, who had dark hair and glasses. "You were walking with Rias Gremory, one of the Great Ladies of Kuoh." He pushed up his glasses, making them reflect light off the lenses. "But before that, you were met by Koneko Tojou, the mascot of the school. And not to mention that Akeno Himejima, the other Great Lady of Kuoh, is in one of your classes."

Again, Aidan was undeterred. "And your point is?"

"Explain yourself, Kain!" the third, Issei Hyoudou, demanded. "How is it that you, the new guy, was able to score a hit with the most wanted chicks in the whole school! We've been here the longest and we've never got laid dammit!"

"Isn't because you guys are just perverts? Hence the title the Perverted Trio?" asked Aidan casually, if not a bit confused.

That didn't sit well with the three as they all gave angry glares, feeling like they were insulted. But Aidan was unaffected by it.

"Look, you three," Aidan sighed as he closed his eyes briefly and opened them back up shortly afterwards. "I am in a bit of a hurry to see my uncle. So if you would please—"

"No way you are getting out of this so easily!" Matsuda exclaimed.

"Come on, help a brother out! All we want to know is how to get babes like you did in just 24 hours!" Motohama pleaded.

"If you don't help us, we'll rally all the jealous males and hound at you!" Issei comically threatened.

'You know that wont do you any good.' Aidan rolled his eyes at that thought.

"Look guys, for one you should stop peeping on girls because their physiology is not what you should be so fixated on. Second, treat them with respect and dignity and not as your toys and you just might get what you want. But considering your nature, you may as well die alone. Third, get a life."

And with that, Aidan head chops all three of them and they all fall to the floor unconsciously. The girls who saw this squealed like fans.

"Did you see him take care of those three perverts?"

"He looked so cool when he entered the school. He's gotten even more cooler for teaching them a lesson!"

"I feel funny when his eyes look on me like that!"

"I love you, Aidan! Please marry me!"

Aidan didn't mind the fangirls at least but wanted some peace and quiet. And luckily enough, after he exits the classroom, he finally gets some peace and quiet, only to be interrupted a few minutes later by someone else.

"Excuse me," A voice called out to Aidan in the appearance of another handsome but younger man than Aidan. He had short blonde hair, gray eyes, and a mole under his left eye. "Are you Aidan Kain?"

"Yes. And you are?" asked Aidan.

"Forgive me," the man said with a bow. "I'm Yuuto Kiba. I was ordered by Rias Gremory to come and see if you were in any trouble. By your tone, I say you are."

"I am sorry about the violence earlier," Aidan said. "But I do not tolerate such perversion, especially amongst men."

"It's okay," Kiba said with a kind smile. "I'm already aware of the rumors spread, though I do not believe in all of them. Come on, we best not keep the President waiting." Kiba turned around and walked ahead of him as Aidan follows, walking side by side with the fellow 2nd year.

Along the way though, girls from around the school saw the sight of the two handsome boys.

"Do you see that? It's Kiba and the new transfer student."

"They look so dashingly handsome."

"The Prince of Kuoh and the transferee. Look at how they look alike yet opposite."

"But if Kiba is the Prince of Kuoh…"

"Then that means Aidan Kain is…" They then said it all together. "The Dark Prince of Kuoh! KYAAAHHH!"

Aidan did not know what to say, other than being charmed by the girls' gossip talk.

"You always get these sorts of rumors and titles, Kiba?" asked Aidan.

"You have no idea," Kiba smiled. "I don't mind it though. I cannot say the same for the other jealous males, whom I also do not mind."

Speaking of jealous males, all of them that saw the two princes could only glare angrily and sneer. But both boys ignored them as they arrived at their destination.

The old schoolhouse building was, as it said, old. A lot of plant life covered it but the building was mostly intact, even if it looked old-fashioned. They may have replaced the old decrepit wood with stronger stuff.

Walking up and entering through the doors was like entering into a haunted house of sorts, or rather a very old mansion dating back to the early 1900's. There hardly any lights, with only sunlight provided through the windows. Surprisingly clean, it didn't look like it needed any attention on its structure. As Aidan followed Kiba up to the second floor and further inside the building, he noticed down the left end of a hallway a door with many locks and chains attached to it, along with police tape for some reason.

The sign on the door said Do Not Enter!

"Kiba," Aidan called out. "What's in there?"

"Something only certain club members know of," Kiba answered. "I wouldn't go in there though if I were you."

"Just curious is all," Aidan revealed as he continued following Kiba through the corridor to another door.

This door did have a sign that was all over the door. It said Occult Research Club.

"President, I have brought him," Kiba announced after knocking a couple times on the door.

"Come in," Rias' voice allowed from behind the door.

Upon entering the doors, the room was completely dark, with window curtains closed and only lit candles to provide light, giving the room a creepy feeling. Aidan was used to this kind of lighting though since he also uses candles in a dark room rather than natural lighting. There were no tables or chairs but rather signs and words all over the walls, ceiling, and chalkboard; most likely written in the Devil's language whatever that may be. Drawn on the floor at the center of the room that took up a lot of space was a large magic-designed circle, for what purpose Aidan did not know.

Looking at the far end of the room, Aidan saw that there were a couple of sofas facing each other with carpet underneath them and a coffee table between them. One big office desk was up at the front.

Aidan then saw someone sitting on one of the sofas eating a chocolate treat on a stick.

"Koneko?"

Koneko stopped snacking before turning to look at Aidan.

"You know of her?" asked Kiba.

"We met on the rooftop once," Aidan said. "Gave her half of my cookie."

Koneko and Aidan stare at each other for a minute before she goes up to him and lifts her head up. Aidan is confused for a minute before Koneko lifts it a couple more times. Aidan then understands what she wants.

"A headpat, huh?" asked Aidan. Koneko nods.

'Not much of a talker it seems.' Aidan thought as he pats Koneko's head, making the white-haired girl purr.

Aidan stopped as he heard the sound of flowing water hitting on the hard floor. Looking towards the direction of the sound, he was surprised to find a bathtub with the shower curtain closing off a section of the room, along with its occupant.

The shower stopped and a pair of wet feet stepped out of the bathtub and onto a towel.

"President, the shower is yours," said another female voice from behind the curtain.

"Thank you, Akeno," Rias replied.

The girl named Akeno was beautiful and young. And like Rias, she had a voluptuous figure that could rival any other girl. She had very long jet-black hair and violet eyes. The hair was tied up In a ponytail, reaching all the way down to her legs with two strands sticking out from the top and sloping backwards, with an orange strand keeping it in place.

Aidan could not help but blush a bit, something Koneko caught up on.

"Why are you blushing?" Koneko asked but Aidan shook his head a bit to shake it off and cleared his throat a bit to regain his composure.

"So you're here," Akeno said, now on the other side of the curtains and wrapped in a robe. "You're our new club member, right? It's nice to officially meet you." Akeno gives a polite bow.

"Likewise," Aidan bows back. "Aidan Kain."

"Akeno Himejima," Akeno introduced herself.

The shower curtains opened up to reveal Rias with a towel in hand, whipping her long hair. "I'm sorry to keep you waiting, Aidan. I didn't have time to wash after leaving your home, so I hope I didn't tax your patience."

"It's alright," Aidan understood. Rias then moved to the front of the office desk and leaned against it with her arms crossed, as everyone else sat down on one of the sofas. With Koneko and Kiba on one couch, Aidan sat on the other and all eyes turn to Rias.

"Now that everyone is here, I would like to introduce our newest member. Aidan Kain, welcome to the Occult Research Club. But the title is just a front of what we are. While it may look like an after-school activity club, everyone in this room, Aidan, are in fact Devils."

"…As I figured."

Everyone in the room had their eyes widened, except for Rias.

"You are not surprised by this fact?" Akeno asked curiously as she passed the tea.

"Since Rias told me that she was a Devil, I had also assumed that everyone else in here would be Devils. Your disposition was easy to read."

Aidan takes the cup presented to him and takes a small sip.

"Good tea, by the way," Aidan says to Akeno.

"Why thank you," Akeno blushed with a smile. Aidan then gets back to the topic at hand.

"I take it you brought me here because of last night with the Fallen Angel?" asked Aidan.

"Yes, that is—" Rias soon stops herself. "Wait, how did you know your attacker was a Fallen Angel?"

"He made himself well-known to me, for one thing," Aidan said. "And not all humans are not aware of the supernatural, especially of the Three Factions."

Everyone was once again surprised, even Koneko stopped eating her snacks and stared at him in amazement.

If Aidan knows of the Three Factions and their existence, he could present a possible threat. But Rias brought him back to life and made him her servant. If anything, he could've killed her this morning with something of a holy artifact that Devils cannot resist against or even become a Stray Devil in the near future.

With that in mind, she decides to test him.

"Alright, Aidan. Let me ask you then. What are the Three Factions?"

Aidan answers it calmly in his normal pace.

"As the name implies, there are three factions of races originating from Heaven: the Angels, the Fallen Angels, and the Devils. All of them, before the latter two's fall from grace, served God equally. But when Lucifer and his brethren rebelled, he and a third of Heaven's angels were cast out, becoming Devils or Fallen Angels in the process. Soon, the Great War came and after millennia of fighting, all three sides pulled out of the conflict, but no truce has been made. Since then, a cold war has been ongoing for a long time now."

Rias was surprised. She then asks another question.

"Then, Aidan. What's the current status of the Devils?" She asked.

"Since many of the Devil population was wiped out in the war, they began making pacts with humans for a price in order to repopulate their species. I would not say that you are all a dying race but rather your influence and power have waned down since the end of the war."

Rias was once again surprised, as was Koneko and Kiba. Akeno seemed intrigued though. It is clear that Aidan knows more than what he seems. But how did he ever come across such information? More importantly, what does he know that the others do not?

Aidan then ventures into his own personal mind.

'Perhaps they are unaware that the Great War is just merely a small part of the Eternal Conflict, like the Sin War millennia before them.'

To Aidan, he thinks the Great War is just another war like the Sin War, all three sides influenced by the High Heavens and the Burning Hells for control of the mortal world. But the truce at the end of the Sin War was already made and while the demons had obviously broken this pact, why would the angels from the High Heavens break it as well? Or have they entirely?

The archangel Tyrael of the High Heavens was the only one to have intervened on the world's behalf on a few occasions but not on something like this. And the circumstances at the time were much different. He did so to prevent mankind from falling into the influence of the demons, not out of the High Heavens' concern or favor since they still see humanity as a potential threat to them.

Even without the Three Factions realizing it, they are already part of the Eternal Conflict. Or do they already know yet are not willing to share it with the rest of their respective species?

"Is everything okay?" asked Rias in concern. Aidan sets his cup down and relaxes.

"It's nothing," Aidan reassured. "Just one question though: why am I being targeted by Fallen Angels?"

"That is easy," Rias said. "It was their mission."

"Mission?" asked Aidan.

"From what I know of, you carry something dangerous, an artifact of great power. Once the Fallen Angel confirmed it, he attempted to kill you."

"But what artifact could I have that could deem me a threat?" asked Aidan.

"If I had to guess, it would be a Sacred Gear."

Aidan felt a bit conflicted. "Sacred Gear?"

"A very irregular, but overwhelming power bestowed in certain humans," Akeno speaks as she sits down on the sofa. "Most of them were found in people whose names are remembered throughout the course of history, using their powers to make them legends. They are found within a person's body, so you can say that with the Gear comes the fame."

"Precisely," Rias nodded. "Most of the Sacred Gears have functions that are only usable in human society. However, there are exceptional Gears out there that are so unstable that they become a threat to those on both sides of the Underworld."

Aidan once again goes back to his own personal thinking as he looks down in reflective thought.

'This is something Uncle may want to hear. What if the Sacred Gears contain fragments of the nephalem? I know there are dragon spirits within certain Sacred Gears but what of nephalem? Or angel or demon? Moreover, why were they given to humanity in the first place? Was it a chance to defend themselves against the demons?'

"Aidan…" Rias snapped Aidan out of his thoughts. "I want you to hold out your left hand." Following her instructions without asking, Aidan does so. "Now, close your eyes and imagine the strongest thing that comes to your mind."

Aidan does so as his mind traces back to his dreams. Of the battles between the High Heavens and the Burning Hells. Demons and angels fight constantly as both sides with such strong power and weaponry change the structure of the battlefield. What could, among the angels and demons, be the strongest weapon there is?

Was it Solarion, the Spear of Valor belonging to the archangel Imperius? Or even El'druin, the Sword of Justice wielded by the archangel Tyrael? What strongest weapon could there be amongst the Heavenly Host of the High Heavens?

But as Aidan ventures deeper, something takes hold of his mind. A throbbing yet annoying pain strikes his head like he was having a headache. He could see dark corridors of ancient tombs lit by only torches on the walls, demons crawling on the floor, unholy artifacts powered up and ready to unleash hell.

Everything soon went black.

Then, from the shadows, the demon he saw at the end of his dreams appeared once again, roaring in its unholy glory.

"…Aidan… Aidan… AIDAN!"

*GASP*

Aidan snaps out of his brief vision with a gasp before backing off a bit and holding his head. He looks up to see a worried Rias up close in concern for him. Her hand on was his right shoulder.

"…What… was I—"

"We were calling you for a few moments, but it looked like you were in a trance," Rias said. "Are you alright?"

"Y-Yeah. I think I just… need a few moments to relax. Clear my head."

Akeno prepares a much warmer tea and presents it to Aidan before Koneko offers a cookie treat in concern.

"T-Thank you," Aidan thanked as he was led to the sofa to sit down on. Rias stayed by his side and sat next to him. She checks his head to see if he has a fever, but luckily there wasn't one.

"What happened, Aidan?" asked a concerned Rias.

"I was doing like you asked and…" Aidan said before he briefly stopped. "It was…chaos. Violent. Indescribable to me. I couldn't imagine the strongest weapon."

"Well, there must be something that's holding you back. Something on your mind, even?"

"My senses must've been overwhelmed by something. What it was I do not know. I'm sorry."

Rias felt a little saddened to hear of this, but she understood since Aidan is still new to all of this. But she also felt more and more intrigued about Aidan. If Aidan is someone who could see visions, then maybe his Sacred Gear is something related to foresight. But no Sacred Gear she knows of has foresight powers, unless this is a new Sacred Gear embedded inside of Raiden. She doesn't want to force it out of him, since she needs to let Aidan sink in the fact that he has now been reincarnated.

And on that note…

"There is something you I did want to ask though," Aidan asked looking up to Rias. "You healed my wounds and said I am indebted to you. But what did you mean exactly?"

Rias looked at Aidan before she took out something from the right side of her desk and held it up.

"Do you remember this?" asked Rias.

"A flyer?" asked a confused Aidan.

"I asked Koneko to give this to you and she did. You were probably unaware of it at the time."

Aidan looks at Koneko as the white-haired girl stares back while sitting next to Aidan. Turns out that Koneko slipped something into Aidan's backpack and he was not aware of it. Probably because he had been busy with his personal stuff and the fact that he was caught in a fight with a Fallen Angel.

"If you were aware of the pamphlet and if you'd died farther away from the school, it would have summoned me to you," Rias said. "Like I said, I watched your fight and when you were near dying. I saved you before death could claim you, but just barely. So I decided to make a gamble."

"For what purpose?" asked Aidan.

"On that night, Aidan, I revived you and made you into an honorary member of the House of Rias Gremory—daughter of the Satan, Zeoticus Gremory."

Suddenly, two black bat-like wings appeared from Rias' back.

"And that makes you my servant, Aidan Kain."

On her commanding gesture, everyone else in the clubroom stood up and spread their wings from their backs. Aidan was left ajar at the sight. Even though he knew they were all devils, he didn't think wings would be a part of their physiological nature.

And yet, Aidan could not help but wonder if these wings were a bi-product of the Devils from a time when they were known to the demons of the Burning Hells?

"Everyone, please introduce yourselves," Rias said.

Kiba was up first as he smiles at Aidan. "My name is Kiba Yuuto. A second year at Kuoh Academy like you. And I am the Knight of Rias Gremory. Pleased to meet you."

Koneko bows her head. "Koneko Toujou. First year. Pleased to make your acquaintance. I'm a Rook of Buchou."

Akeno bows her head very politely like any Japanese woman would. "My name is Akeno Himejima. I'm a third year and vice-president of the Occult Research Club. I am also Rias Gremory's Queen." She then ended her statement with a giggle.

Aidan was amazed by their appearances before he too felt something prod up from behind. He looked to see he also has wings of his own.

"Welcome to the club," Rias said. "How do you feel?"

"To be honest, not much different," Aidan honestly stated, surprising the others once again. "Still, I could've been turned into something much worse."

"Well that's good. Now we can get straight to business," Rias said as she conceals her wings and goes behind her desk to sit. "The way the life of a Devil works is we grant powers to humans for a price that we both agree on and seal the deal with a pact. It used to be that people would draw summoning ritual circles to call for us, but it became too complicated for the human mind to comprehend. So, to make things easier, we make personal house calls and deliveries by handing out flyers."

Rias then stood back up and walked over to a table to set down a white bag full of the flyers. When Aidan opens it up, he sees them as the same pamphlets that were given out by the club members.

"Normally we'd have a messenger make the deliveries, but as a new servant, Aidan, I thought it would be best to have you do it so that you could learn from all this."

"So what do I get for doing this?" asked Aidan.

"Well," Rias then whispers into his ear as she puts a hand on his shoulder. "You could have servants of your own."

Aidan blushes a bit before he composes himself and clears his throat. "That's not what I meant. I meant to ask what do I get in return for being your servant and performing these tasks? Don't get me wrong, I am grateful for saving me, but what do I get in return for your prestige?"

"Well, what do you want?" asked Rias curiously.

But Aidan soon countered with the same question, "What do you want most?"

Rias was surprised yet intrigued. Aidan managed to deflect the question back to her, giving her an amusing smile. An idea then pops into her head as she states,

"I was told by a close friend of mine that you had managed to gain access to a secret area of the school's library accessible only to the Student Council. But I wanted to confirm if that was really you."

To further emphasize her point, Rias pulled out two books that were all too familiar to Aidan; The Seven Evils and The Horadrim. Aidan was stunned. He didn't think Rias would have connections to the Student Council that would allow her to know what they know. Perhaps someone there is a close friend of hers willing to share information.

To Aidan, he knew that the information he found was nothing but mythology and folklore, at least to the Devils. But he and his Uncle knew that they were no myth.

However, Aidan felt that they must not know yet. For if such stories were true, then Aidan would need proof, yet he had none bar his own personal knowledge. But for starters, he can confirm one thing.

"Yes. That was me that day. I was the one who gained access thanks to my Uncle who had the key."

"Strange that you say that," Akeno popped up. "The key is meant to be used by the Student Council only. So how did your uncle acquire it?"

"I can only wonder," Aidan inquired, dodging the question.

"What were you even doing in there?" asked Kiba, but again, Aidan dodges the question.

"Who knows, really?" Aidan surprised everyone. "But I will tell you this. When circumstances permit me, then I will tell you."

"I suppose we can deal with that later then," Rias stated. "Oh, and one more thing Aidan. You will have to call me President from now on."

"Why?" Aidan asked curiously.

"Not only because everyone in the club calls me that but also hat the school is an active territory of mine. So, it should be fitting to be called as such."

"That is a most logical conclusion," Aidan agreed. "So what must be done today?"

"First I need you to start handing out the flyers," Rias said. "Since you can't summon your Sacred Gear yet, the best course of action is for you to take it easy and adapt to your new life. I'll need you to deliver these tonight. They will be your first of your batch this week."

"Understood," Aidan said.

"Before you leave though, there is something I want to give."

Getting out of her seat and walking towards Aidan, Rias stretches out her arms with her eyes closed. A red glow illuminates the room, especially on the large circle drawn on the floor.

"This magic circle is used for transportation; thus you can arrive here at any time. Hand me your palm, please."

Aidan does as ordered with his right hand. Rias grasps it and traces with her right hand before a symbol was shown in red.

"This is the mark of my family, the Gremory Clan," Rias said as Aidan looks at it. "It will allow you to be teleported to the client's location, where you'll just do everything I've taught you to do. But in order to make the jump, you must be at a certain level of power. Since yours is still too low, the circle will not activate."

"Understood," Aidan acknowledged. "But not to worry, President. I think I can manage without it in the meantime."

A confident Rias smiles at him. "I'm sure you will. Koneko, bring out the other boxes of flyers."

Koneko then delivered seven large boxes containing the same flyers, dropping them in front of Aidan. Looks like it is going to take a lot more than tonight just to empty all of them.

But luckily for Aidan, he has a few tricks up his sleeve thanks to his travel experiences with his Uncle.

After just about half a week later, Aidan finished his first task. It was already nighttime just as he finished the last of the flyers. But the night was cold and dark. Aidan would not have been able to see had it not been for the lamp posts.

As he walked Aidan had much to ponder on.

'One week into the Occult Research Club and the first thing she has me do is deliver flyers. Not that I do not like being delivery boy, but I suppose everyone has to start somewhere. Still, I wonder what Uncle will have to say about all this? He certainly knows more information about the Three Factions than they know combined. I wonder if me being with the Devils will bring him closer to the answers he seeks regarding the Prophecy of the End Days?'

Aidan's thoughts soon stop to look at the night sky. But he was not looking at the stars, rather his thoughts were about Rias. The beautiful red-haired girl that slept with him, albeit with no sex involved, whom Aidan could not help but feel enraptured by her appearance and beauty.

She was strong-willed, kind, and caring. She had the qualities of a leader. She could even rise to be a powerful figure in the Devil world. But would Aidan be there to see it? And would he be at her side forever?

But such thoughts are only trivial, an illusion at best. Reality must be attended to, and with the forces of darkness moving from within the shadows, Aidan must be cautious. The demons from the Burning Hells could pop up from anywhere for they have not forgotten about this world.

Just then, Aidan felt a presence lurk behind him. He stops walking and processes the sudden change in the air. But he had felt this feeling before. It was the same one that he felt in his encounter with Dohanseek.

Another Fallen Angel of the Grigori.

Turning around, Aidan looks to see a tall and buxom woman with long, navy blue hair and an obscured right eye from one of her two brown eyes. Her attire consisted of a violet, trench coat-like top with a wide collar, a matching miniskirt, and black heeled shoes with a gold necklace around her neck.

"So you're the one," The Fallen Angel said. "Dohnaseek's killer. I was sent here to find and kill you."

"I take it you're not here for justice though?" asked Aidan.

"Quite right," The Fallen Angel said. "Interesting. This is so unusual. You do not seem intimidated by me in the slightest."

"No surprise when I have encountered your kind before. What's your name?"

"Kalawarner," The woman introduced herself. "Dohnaseek should've killed you that night but it seems our analysis of you was off. You were not only able to defend yourself but also kill one of my kind. So, I guess I will clean up his mess."

Kalawarner soon conjures a light spear in her hand, which looked like a yellow double-bladed sword-like spear with one end bigger than the other, and throws it at Aidan. But Aidan moves out of the way in time to dodge the attack by jumping diagonally to the left.

Once Aidan lands safely, a red mark glows on Aidan's right hand.

"Is that the Gremory family crest?" Kalawarner asked in surprise. Then she becomes amused the next moment. "Interesting. The fact that you are now a member of the Gremory household makes it all the more important to destroy you!"

Aidan was undeterred as he prepared himself for the next attack. Since he has no weapons at his disposal, and the fact that his crossbows were defunct after the battle with Dohnaseek, all he could do is dodge.

Kalawarner conjures another light spear and throws, making Aidan dodge again. But Kalawarner kicks him straight in the stomach with the heel of her foot. Luckily Aidan manages to catch her foot and stand his ground as he slides back about fifteen feet, but not before feeling the impact of the kick course through him at first.

Grabbing the leg, Aidan empowers his left fist with some demonic power, pulls Kalawarner toward him, and throws a gut blow in return. It was enough for the Fallen Angel to receive a blow but not enough for her to be out of commission. She spins and throws a spin kick with the back of her heel at Aidan's head, sending him flying a few meters to the left.

Grunting in pain and adjusting his vision, Aidan sits up and shakes his head.

"That was a good one," Aidan complimented. But Kalawarner took that into credit.

"That's right," She said haughtily with a smirk. "You cannot hope to win against us. You were only reborn a week ago, but we have existed since the days of our fall from grace. Now make this easier for me and die a second time."

Kalawarner conjures another light spear to throw at Aidan whom he dodges, only for Aidan to see the Fallen Angel charge at him with another light spear at the ready to impale him. But Aidan will not fall for it as he holds back the light spear.

Aidan was now in a sticky situation. He could not defend himself much longer, even with the new devil power coursing through him. He was not strong enough. If only he had a Sacred Gear to call out for, he may have a chance. But alas, fate has to be cruel onto him on this night. He could only dread what it will be dying a second time.

Thinking fast, Aidan headbutts Kalawarner but the Fallen Angel's head was strong. Despite taking the hit, Kalawarner returns the favor with a headbutt of her own, one which makes Aidan fall to the floor backwards.

"Time to end you, Aidan Kain!" cried the Fallen Angel. Sprinting up towards him, Kalawarner prepares to give a downward slash to end him once and for all. Aidan had another empowered punch at the ready as he sits up to land another gut blow to Kalawarner.

The two combatants meet in the middle, with death at the ready to take away only one soul.

*PSSHH*

A sound of flesh and blood was heard to show a very gruesome setting. Just as Kalawarner was about to end Aidan, something felt warm on her stomach. Warm and wet and decorated in red and covering much of her outfit.

It only took her a few seconds for her to start spewing blood from her mouth in a big puddle. When she hazily sees her blood, she looks down to see her stomach pierced by six blades, three on each of Aidan's fists, going straight through her stomach and out her back.

She was so close. Close to defeating him. She could've ended it once and for all by her own blade. Dohnaseek could not do it last week, so she should've done so tonight and avenge her fallen comrade.

And yet, as Aidan turns the claws to finish killing her, her body limps a bit before Aidan pulls them out. More blood is splattered out of Kalawarner's mouth as she looks at her triumphant foe, her blood splattering over Aidan which he does not mind.

"Damn…you…" The last words of the Fallen Angel spoke.

With that, Kalawarner's eyes roll backwards as she falls back to the ground, lifeless and pale. Her body soon dissipates into black feathers and all that was left were those said feathers and her pool of blood.

Aidan stands up yet winces in pain. That kick Kalawarner made on his head made him bleed but it was not that bad. And luckily for Aidan, he just happened to carry a healing potion, one last bottle. Taking it out of his pocket that somehow did not shatter, he pops open the cork and drinks it, his head wound slowly healing up.

"Much better," Aidan said. Then he looks at his Sacred Gear. It was in the form of a black, demonic-like gauntlet that procured three long, elongated wolverine claws at the same length. The blood of Kalawarner drips from those claws and Aidan can hear each drop hitting the floor.

As Aidan looks at it, a shadowy figure from behind with white eyes glowing red watches him. Aidan then felt something he never wished to feel when looking at his new weapon.

Terror.

The second chapter is now finished. And with that, Aidan is introduced to the Occult Research Club and to his Sacred Gear. What it is called it will be named next chapter but the very last word of the chapter should give you all a hint as to what this Sacred Gear is. And if that were not crazy enough, he knows much about the Great War between the Three Factions, along with some history not known to them.

But here begins his first week as a member of the club and a pawn of Rias Gremory. One can only wonder what else awaits him. And do not worry as I do plan for him to do some contract work with clients. That is where some recognizable people from Diablo come in, say the classes from Diablo III. OOPS! Spoiler Alert!

So many references to Diablo but I feel like it is well put in. Let's just say that there is a history unknown to the Three Factions that concern something much greater than even their minds can comprehend. If they all thought the Great War was a rough period in their history, just wait until they hear about the Eternal Conflict.
