So I decided to do a High School DxD fic because why the hell not. I recently restarted watching the anime and began to read the manga and I find the story quite entertaining enough to make a story.

This story will be OC centric with my new OC named Roman. While he will be the main character of the story, Issei will also be a part of the story. Honestly, if it was not for the Sacred Dragon gear, I would not bother to have him in the story at all as he annoys the hell out of me. I was even considering removing him from the story despite having the sacred gear and I am still considering it at this point.

As for pairings, I always do single pairings in my story but I think for this one, I might switch things up. The main pairing, though, will be with Rias.

It's a quick chapter, originally meant to be the first half of what I was intending for the first chapter but I decided to shorten it and make it an introductory chapter instead.

So here it is, I hope you all enjoy the read and let me know what you think. Be sure to read the author's note after the chapter as I have more things to say as well as inform you of the changes I plan on making canon-wise in the story.

The Lost Heir

CH.1

Say Goodbye to the Normal Life

It seemed as if time had slowed around Roman. The demolished structure that was his home crumbled around him as the figures of unfamiliar people continued to fight above him.

These weren't people, though. People do not have large wings sprouting from their backs that allow them to fly!

This statement kept going through his head as he stared at the winged people flying above where his roof used to be, fighting each other in midair with swords and spears. Some of them had black feathered wings while the others had smooth black leathery wings with pointed ends.

"Roman! Get out of here! Run!" one of the leather-winged "people" flew down to him. He was young looking and wore a white dress shirt and grey slacks while holding a broadsword in one hand and a large round shield in the other. He looked worried but Roman did not know why he should. He did not even know this young-looking man. He doesn't even know how he knows his name and yet he is calling out to him.

A ball of fire flew down at them but the winged man came down and protected them both with his large round shield.

"You gotta get up, pal!" the man said to him and helped him up. "Make a run for it! We'll try to hold them off!"

Another fire blast came down near them, causing them to look up in the sky where they saw the other leather-winged guy fighting in mid-air with a feathered-winged guy clad in a trenchcoat and a fedora.

"Go!" The guy said one last time before flying off into the sky.

Doing as he was told, Roman made a run for it to get to safety. Where to run, he did not know. His first thought would be to his home but this battleground was his home.

Another fireball exploded near him, causing him to fall back onto the ground and knocked off his thick-lensed glasses. Blind, he frantically scoured the ground for them until his fingers bumped into the familiar black rims of his glasses and put them on, though he wished he had not after what he saw before him.

His father was lying on his side, unmoving with a growing dark red hole marring his white shirt as the blood continued to pool around his lifeless body.

Roman's mother though was still alive, only barely. Her whole broken and bloodied body heaved as she took in each painful breath from her jarred mouth that blood trickled and bubbled from the quivering corners. Her blue glistening eyes stared at him, wide and scared as she tried to speak to him.

"Ro...Roman…" She managed to say, her voice barely audible and trembled with every haggard breath she took to speak to him. "I...am...sor—"

A sudden sharp blast erupted in the air and Roman felt a sudden spatter of something hit his face that caused him to close his eyes.

He did not have to open his eyes to know that it was blood that spattered on his face. The metallic taste and smell invaded his mouth and nose and against his better judgment, he reopened his eyes seeing his lenses spattered with blood and found the source from where it came.

His mother was calmly staring at him with her glazed blue eyes that had tear streaks falling from her blood-spattered face. In between her eyes was a small dark red round hole where her blood profusely trickled down her relaxed face.

"Mom?" Roman hoarsely croaked. He took a painful gulp to swallow back the emotions that began to overwhelm him. His mother, the kindest woman he has ever met, and his father, the best man he knows, were lying dead before him.

Just as he was about to reach out to his mother, a heavy boot slammed down on his arm. The pain was excruciating and only got worse as the boot pressed harder on his already injured arm.

A pained howl escaped Roman's mouth and he tried to shove the boot off of his arm but the effort was futile. He hated being a weakling.

"This has to be the most disappointing mission I have been on." Roman heard a bored sounding voice of the man stepping on his arm. "Belial had entrusted one of his most valuable possessions in their hands and yet they were so easy to put down. I have to say, humans are such weak creatures."

The man finally removed his boot from Roman's arm, allowing for a bit of relief before using that boot to roll him over on his back to finally face the assailant.

It was clear that the white-haired young man was a psychopath. His red eyes stared down at him with an evil yet gleeful look to them. It was obvious that he enjoys doing this. What made it even scarier to Roman was that this man was wearing the garbs of a priest and yet he looked anything but one, especially with a sword in one hand and a gun in another. It was like looking at a wolf in sheep's clothing.

"Raynare, you told me this was going to be fun, and yet the only ones I see actually having fun are Dohnaseek and Kalawarna. If I knew my job was going to be over so quickly, I would have taken my time with them. Are you sure this is him?"

A sudden small gust of wind breezed past Roman's face as he hears the soft fluttering of wings approach followed by the crunch of footsteps touching the ground and making their way over toward them.

Roman's gray eyes turned to the incoming figure and widened as he recognized the young woman in the scantily clad garb of his girlfriend, Yuuma Amano.

It was not just the outfit she wore that was different but also the personality she was radiating. By nature, Yuuma was always so sweet and kind. Now, she looked down at him with disdain and confidence that radiated from her in a manner he has never felt from her since they became friends and it frightened him.

"Oh, I am sure of it." Yuuma said with a sneer as she glared down at him. Even her voice went down an octave that made her even more unrecognizable to him. "My intel is good. He is the one we have been looking for."

Roman did not understand what was happening. Why was this happening to him? Why was his only friend doing this to him?

"Yuuma…" Roman shakily uttered, feeling betrayed and hurt as he stared at her. "Why? Why are you doing this?"

"Why am I doing this?" She chuckled at him and the crazy priest joined in with her. "Because we are mortal enemies, you and I."

Roman never felt more confused than he felt in his life. Mortal enemies? How can they be mortal enemies when they have only known each other for a few months?

Yuuma, or Raynare as she is being called, could see that this was not making sense to Roman.

"Wow, you really do not know do you?" She asked, sounding both amused and amazed. "Your parents were really good at keeping the secret from you, weren't they?"

"What secret?" He asked. Roman could feel his emotions getting the better of him and his eyes glistened as tears began to well and trail down his dirt and sweat streaked face. "Answer me Yuuma!"

"Yuuma doesn't exist. My name is Raynare." She said calmly and crouched down to be closer to Roman.

"You were my friend." an angry Roman sniffled, attempting to hold back his tears. He did not want to be seen crying, especially in front of these two. "My girlfriend. I was in love with you!"

Reaching out, Raynare gently caressed Roman's cheek and wiped away his tears. He tried to pull away from her touch but he could barely move his weak and exhausted body.

"Roman, my sweet Roman." She said gently with a sweet grin yet she looked anything but sweet. "It was all an act. All leading up to this."

It was brief and maybe it was a trick of his mind but Roman could have sworn that he saw a break in that mask of confidence she wore and saw a glint of regret.

"Despite it all, I did enjoy our time together. You were a nice guy, Roman. One of the few truly nice guys that I have met. I will cherish our time together."

Raynare gave him one last look before getting back up to her full height and spread out her black feathered wings.

"Sellzen, do it." She ordered the young priest. "Make it quick. He has already suffered enough by our hands. Let him go in peace."

"Aww, come on Raynare, let me have a little fun with him." Sellzen pouted like a child. "This has been so boring. He still has some life in him to be skinned a bit, at least. He is just a filthy De—"

The Priest immediately halted his words when Raynare turned back toward him and gave him a deathly glare with her violet eyes that faltered his smile.

"Do as I say, Freed. Do you hear me?" She sternly ordered and flew off after Sellzen reluctantly nodded in agreement.

"That bitch should get off her high-horse." the Priest said through his gritting teeth. "One of these days, I'll show her who's the real power here. It's only a matter of time."

The Priest let out a sigh as his red eyes roamed around at the fighting going on in the sky until they caught sight of Roman still struggling on the ground to get back up.

"Well well well...it looks like it's just you and me now, boy." The Priest sneered down at him. Raising his hand with the pistol, he unloaded the magazine of illuminating bullets to reveal the remaining three left in the weapon and pointed it at Roman. "The lady says I have to do this quickly but what's to stop me from having a little fun. Who is going to tell her? You? A spineless weakling? Just like your parents."

Roman should feel scared. This insane man was pointing a gun at him, itching to kill him for some unknown reason but Roman did not feel scared. He felt angry. More angry than he has ever felt before. His body was trembling with a seething rage unlike what he has ever felt before as he glared at the man laughing maniacally.

"Oh, look at you." Sellzen said with a wide grin and leering eyes. "You are on the verge of dying and still you feel angry. I can feel it radiating off of you. Go on, get angrier! Do it!"

Roman did just that. He got angrier. The more he looked at the Priest and thought of Raynare and what they did to him, the angrier he felt. Even in his dying state, he was still feeling the infuriating anger surge through his body. He did not even feel the pains all over his broken body. In fact, he was feeling reinvigorated. It was as if his anger was feeling him and his drive to keep going.

The Priest somehow seemed to notice this as well and placed his heavy boot onto Roman's chest, causing the younger man to cry in pain as more pressure was applied to his injured body in order to stop whatever was happening to him.

"Oh ho ho! Now I see what Raynare is talking about." The Priest said, impressed with Roman for some unknown reason. "You are certainly more than what meets the eye and I happen to have good sight."

Roman did not know what the Priest was talking about nor did he care but what he did know was that he wanted this man dead and he wanted to kill him. To make him suffer as he was doing to him and what he did to his parents.

"I know what you want and unfortunately, you will not get the chance to exact your revenge on me or Raynare or the ones who led us to you." The Priest aimed the pistol at Roman's chest. His unsettling smile spreading from ear to ear and his eyes widening, giving him a crazed look that would scare any other person. Not Roman though, this man could not do anything more to him than he already has.

Fear no longer a notion within him, Roman swung his arm at the Priest, hitting him in the back of the knee that caused him to immediately collapse to his knees next to him. This was something uncharacteristic of himself, to fight back. He never had it in him but in this moment, with the rage and adrenaline coursing through his body, it was as if he had no control and impulsively reacted the way he did.

The Priest was both surprised and furious with what had happened. No longer amused, he snarled at Roman, his smile no longer present on his livid expression and eyes appeared to be burning red as he glared at the younger man.

"You filthy unholy cunt!" The Priest snarled menacingly at Roman. Without hesitation, the Priest raised his pistol and pulled the trigger, over and over again.

The impacts were sharp and painful but it was not until a while after the Priest had finished unloading the magazine into Roman's torso that he began to feel the pain of the three bullets lodged deep into his chest and stomach. The adrenaline still coursing through his body kept him from feeling the full brunt of the pain but he could not help the panicking feeling as he stared at his chest where the warm blood staining his shirt as it profusely spread across his torso.

He did not feel much pain but he did feel tired. Very tired. All he wanted to do was lay there on the ground and close his heavy eyes. His blurry sight began to dim and all he could hear was a loud ringing in his ear from the gunshots.

Roman could barely hear what the Priest was saying, his voice muffled and distant, but he did see him suddenly run off into the distance. When he was gone, Roman turned to the lifeless bodies of his mother, eyes still staring at him.

"I'm sorry. I am so...so sorry…" Roman could not stop apologizing to them both, feeling it was his fault that he could not protect them. His guilt felt far more painful than any pain coursing through his body.

Laying there on the ground, everything dimming around him, Roman succumbed to the darkness, wanting nothing more than to feel nothing anymore. No pain. No sorrow. No guilt. Death felt far better than living anymore.

Before darkness completely took him, Roman saw two blurry figures flying down to him, one of whom he recognized as the one who told him to run away. Roman tried his best under the circumstances.

"It's going to be okay...Roman…" He could barely hear the guy's muffled words over the continuous ringing going through his ears.

The darkness finally came, consuming the world that Roman knew and would leave behind once and for all.

"This is the end."

In that darkness, Roman saw a pair of eyes blazing like fire staring at him.

"No...this is only the beginning."

Well, that is the first chapter. It's short and a bit sudden as it is just an intro to the story but expect the rest of the chapters to be longer.

So as for the Devil clan Roman will be in, it will be Belphegor. So, in doing a bit of research on the crown Princes of Hell, it got kinda confusing because I got both names, Belial and Belphegor, contending as the Prince of Sloth. I also know that the names are two different clans in the DxD universe and both of them are not considered high-ranked families, at least from what I have read on the wiki site. I have yet to meet them in both manga and anime.

So, I did what a fanfic writer does and changed a few things. For my story, the Belphegor Clan is going to be a very prestigious family within the Pillars and hold a great deal of power including holding a position as a Great Satan.

The Belial clan will not exist in this story and instead, have them absorbed into the Belphegor clan as an extended familial clan to the Belphegors. However, the name Belial will be used as the first name of the Belphegor clans' founder.

Another thing I have decided to change as well was the number of members in the faction. Since there are Seven Princes of Hell, each of them representing one of the seven deadly sins, there will be seven Great Satans instead of four. Also, unlike how the names of the Great Satans are used as titles given to members of other clans, it will be different for the Belphegor clan which will be explained in the next chapter.

So, I think I have said all that needed to be said. If you have any questions or comments, please leave a review or message me and I will respond when I get a chance.
