For anyone who read my Sekirei stories, I'll let you know that this story's tone is a balance between the seriousness and lightheartedness of Chaning the Game and Survival of the Fittest. Obviously, this isn't related to Sekirei in any way, as it's not a Sekirie crossover. The Sekirei crossover that I've been working on will get started soon as well for anyone who is interested in it. Anyways, I hope you enjoy this story! Highschool DxD and Code Geass really need more crossovers.

Chapter 1

The history books will tell future generations that today was the day that Lelouch vi Britannia, the Demon Emperor, died at the hands of Zero, fulfilling the Zero Requiem.

Lelouch watched over his subjects one more time as his float carrying the prisoners passed them. They all looked upon him with contempt and disgust, but he didn't care. He wouldn't see them anymore after this. As he planned, the entire procession stopped as a masked figure stood alone in the road ahead.

It took the crowd a few moments to realize who exactly was standing in the road. But by the time Lelouch feigned surprise on his face, he could he people murmuring the name, "Zero."

Without warning, Zero dashed forward and Knightmares fired at an unusually limber Zero, but found it impossible to hit him in time. Jeremiah stood ready to defend Lelouch, but Suzaku quickly passed him and leaped onto the float. Suzaku deftly made his way past all of the hapless guards and drew his sword back.

Lelouch allowed himself to smile. For generations, people will debate about why exactly he was smiling. Only a select few knew the truth about the Zero Requiem.

Suzaku did not show the slightest sign of hesitation as he stabbed Lelouch. As he did, the emperor collapsed into him. Lelouch had to admit, it hurt more than he had expected it to. But then again, it was nothing compared to the pain of having to watch people he loved die at his own hands.

He whispered just loud enough so that Suzaku could hear him, "This is also a punishment for you. You will be the defender of justice and wear a mask forever. You will no longer be able to live as Suzaku Kururugi. You will sacrifice all of your own happiness for the world, eternally."

"I accept that Geass." Suzaku replied, holding back tears.

He pulled out his sword, allowing his best friend to take a few steps before he collapsed and slid down next to Nunally. The world cheered as Lelouch began to gasp out his last breaths with a small smile on his face. The Black Knights appeared out their hiding places, freeing the prisoners and overthrowing the reign of Lelouch vi Britannia. Nunally's face was streaked with tears as she wailed for the loss of her brother.

"Lelouch! I love you!" Nunally screamed at him.

Despite the chaos, Lelouch was at peace. He knew that because of him, the gentler world that Nunally desired could be made a reality. Now he was ready to pay for his actions in Hell. Knowing that he fulfilled his promise with Nunally would make it easier. He could almost see Euphie, Shirley, Rolo, and everyone else beckoning towards him. He was ready to join them.

"Yes…I destroy worlds…and create worlds…"

With one last gasp, Lelouch vi Britannia, the 99th Emperor of the Holy Britannian Empire, died.

Across the Underworld, a feeling of opportunity filled the air. The news that Lelouch vi Britannia was dead spread like wildfire. In his castle, Sirzechs Lucifer could only groan in annoyance as a messenger delivered the news.

"Now all of the clans looking to increase their status are going to go after him." He muttered.

"So what are we going to do about it?" Grayfia asked her husband. She knew that he would not stand for a free for all between the clans, it would most likely be seen as a weakness by the Angels and the Fallen Angels. Sirzechs had to maintain that the Underworld was as strong as ever to prevent an invasion.

Sirzechs sighed, his next move was probably going to anger a lot of clans, but it's not like they could argue with any of his decisions.

"Well, I do miss having a productive Asmodeus." He mused, "I should see if Lelouch could take Falbium's place."

He cracked his fingers.

"Very well then. Lelouch vi Britannia, prepare to be reborn."

Lelouch awoke with a start, his face covered in sweat. The last he remembered, he had successfully carried out the Zero Requiem, but then, how did he survive?

"That was all a dream?" He asked, feeling for a stab wound in his chest, but finding none.

"It felt so real though." He muttered as he checked his surroundings, realizing that he definitely wasn't in his home. He was sleeping in a room that was still regal, but not his palace. He could recognize his own room. For one, his walls were definitely not painted red.

"I assure you that it most definitely was not a dream." A crimson haired man walked in.

"Who are you? And where am I?"

"I am Sirzechs Lucifer, one of the Four Great Satans."

So that explained it. He had died and now he was facing his eternal punishment in Hell.

"So am I in Hell?"

"No, you are in the Underworld, the home of Devils." His response shocked Lelouch. So he was somehow alive, although he did feel different.

"Why am I here?"

"First, I have a bargain to make with you. Second," He began with a glint in his eye, "I need you to meet someone."

Lelouch found himself standing in front of a rather unimpressive castle. Considering that he was now a Duke, he expected better.

"How the mighty have fallen." He muttered as he entered Murmur castle. According to Sirzechs, the Murmur Clan died out during the Great War, but he felt that Lelouch could be used to restart it. First, he made a contract with him, not unlike the one that Lelouch had made with C.C. In exchange for certain requests, he would be rewarded by being reborn as a pure blood demon with all of the powers of the Murmur Clan, as he was now the patriarch of the clan.

He entered the Gothic castle and looked around. It was incredibly dusty, as no one had tended to it in ages. The walls and floors were all made of rock, with a large blue rug leading up the stairs. Purple curtains framed a fifty foot high window with a mosaic depicting the mark of the Murmur Clan. A large golden chandelier hung over the foyer and there was an impressive stone staircase leading to the second floor. He slowly climbed up the stairs and turned to the left, which held two doors, one of which led to the bathroom and the other one led to the master bedroom. He quickly glanced to the right, which only held one door.

He found the door slightly ajar and decided to investigate. He opened the door to find a large library filled with thousands of books. If he was going to have an unimpressive castle, at least it had a substantial library. Besides one of the rows of bookcases lay a small table with a chessboard. Upon further investigation, Lelouch discovered that there was only one set of chess pieces.

"These must be the evil pieces." He muttered as he began twirling the pieces between his fingers as plans already began to form in his head on how to use servants to win Rating Games. More importantly, he began to plan out the next move that would allow him to ascend the ranks of Devil society. He did have a distinct advantage currently.

Not only did he have the powers and abilities of a Super Devil, but his Geass remained. He still had not fulfilled his contract with C.C., so his Geass would remain until he did. He knew that would not be enough to become one of the Four Satans. He needed to get on top before he would have the right to lead an army large enough to defeat the Angels and the Fallen Angels.

After learning about the ongoing war between Angels, Fallen Angels, and Devils, he made the choice to accept Sirzechs' offer so he could end the war. After all, Nunally would not be able to live in a peaceful as long as a war like this carried on.

But before he could even think about ending the war, he had to fulfill Sirzech's requests.

"Hello everyone, my name is Lelouch Murmur." The black haired student said, bowing as he did so. Rias Gremory stared intently at the new student as he introduced himself. Murmur was the name of an extinct Devil Clan, but there was no way that someone as frail as the boy standing in front of the class was a Devil. Meanwhile, Lelouch was just as interested in Rias. She seemed to be the only girl in the classroom who wasn't busy ogling him like his fan girls back at Ashford used to. Kuoh wasn't all that different from Ashford overall. He remembered that the two schools were actually rivals, but Ashford was usually considered a more prestigious school, as it was for Britannians while Kuoh welcomed any students it could get, Japanese or Britannian.

He was directed to the empty seat behind her and next to Akeno in the back corner. As he walked back to his seat, he stopped at Rias' desk, interested to find out who she was.

"Hello, I'm Lelouch." He introduced himself to her with an outstretched hand. As Rias shook it, she almost collapsed from the overwhelming power she suddenly felt radiating from him. There was no doubt that he was a Devil, and a very powerful one at that. There was something else coming from him, although she couldn't exactly pinpoint it.

The only person who she ever got a similar feeling from was Sirzechs, and he was already a Super Devil. She definitely needed to warn Issei to stay away from him. If Issei ever angered him, she had no doubt that Lelouch could annihilate him, Longinus Gear or not.

She tried her best not to show her thoughts to him, "Rias Gremory."

Lelouch's eyebrows raised in surprise. So this was Sirzech's younger sister. Well, they did both have the same crimson red hair. He took a quick look over her. She was definitely attractive, he couldn't deny that. Now he knew why Riser Phenex was so eager to marry her. Although he imagined that Phenex would be eager to marry just about anyone, considering that he was perverted enough to actually make his younger sister a part of his harem. The only time he met Phenex before he left the Underworld had left a bad taste in his mouth, especially as his younger sister made him think of Nunally. No doubt that the man would be one of the obstacles standing between him and a spot as one of the Four Satans.

He took his seat and introduced himself to the black haired girl sitting next to him. She was just as, if not more beautiful than even Rias Gremory.

"Lelouch Murmur."

"Akeno Himejima."

He realized that she was Rias's famous queen, the Priestess of Thunder. He knew about her reputation as a sadist and was surprised to see such a cheerful girl sitting next to him, although he knew that her cheerful persona was just a façade. As the teacher began lecturing, Lelouch suddenly realized why he ditched class so much. The classroom bored him.

As soon as class ended, Rias rushed to the Occult Research Club to call a meeting.

"What is it Buchou?" Issei asked as he entered the club room. He had rushed back as soon as Rias called for a meeting.

"There is a new Devil in Kuoh Academy." She announced.

Koneko nodded in the midst of eating a cake, "He seems powerful." She wasted no words, exactly summing up her feelings about him, although she did also notice that he was a much less perverted man than Issei.

Kiba nodded in agreement, "And he's already gained a large following of fan girls within a day." He shuddered a bit. It had already been agreed upon by numerous fan girls that the Two Great Men of Kuoh Academy as they were dubbed, were already in a relationship with each other. Those girls could make anything up as long as it satisfied their sick fantasies.

"Fan girls? He must really be the enemy of all men!" Issei exclaimed, imagining that Lelouch already had a harem.

"I won't let him get in the way of my harem!" He yelled.

Rias sighed at her pawn's perverted dreams.

"Ara ara, what should we do then, Buchou?" Akeno asked.

Rias' brow furrowed, "I don't know yet, but for now, we need to try and befriend him. If what I felt when I met him is any indication, we'll want him on our side."

"Don't worry Buchou, if he tries to hurt you, I'll stop him, even if it costs me my life." Issei said confidently.

Rias kept a serious face at that, even though she was touched that her cute servant was willing to lay down his life to protect her.

"Issei, I know that your Sacred Gear is powerful, but just his raw power alone might be able to beat you, not to mention I think that he may be wielding some sort of Sacred Gear himself. Please, don't get into any trouble with him."

Lelouch wandered the streets aimlessly, lost in his thoughts. Within a few weeks, he went from the being the Emperor of Britannia to a Devil. Although it wasn't that big of a change since he was already regarded as the Demon Emperor, even before he gained any supernatural powers. He wondered about what had happened to everyone from Ashford.

From the news, he had learned that Nunally had become the 100th Empress of the Holy Britannian Empire. He couldn't help but feel proud of her. Her actions were well received and promoting peace around the world. Also from that new feed, he learned that Milly had done well as a reporter, as she was the one reporting on Nunally and Ohgi's meeting. In addition, it seems that Knightmare Frames were outlawed and most of them were destroyed, much to the chagrin of Lloyd and Rakshata, who were currently fighting to reverse the ban, with little success.

He had also learned that Sirzechs had somehow managed to alter everyone's memory of his appearance, allowing Lelouch to keep his appearance without raising suspicion. It hurt him that Nunally would never recognize him again, but it was worth it if he could bring an end to the war raging on between Devils, Angels, and Fallen Angels.

Before he knew what he was doing, he found himself standing in front of Ashford Academy. His legs had subconsciously brought him there, but he could go no further. He was afraid that if he went inside, he couldn't bear to come back out. There were too many memories. Milly, Rivalz, Nunally, Suzaku, Shirley, Eupie, they would all come back to haunt him. Euphie and Shirley especially. He desperately wanted to apologize to them.

"Why Lelouch?"

Those words had haunted him up to his death. It wasn't bad enough that he had killed his sister, but he had killed his one love. He could feel the tears coming. Ordinarily, he would not let his emotions show, but here, he could bear it no longer. His knees felt weak and he allowed himself to fall to the floor.

"I'm so sorry, Euphie." He choked out between sobs.

"I know." Lelouch could almost feel her ethereal touch. He kept his eyes closed, not daring to ruin the illusion his mind had created.

"Open your eyes." The voice commanded. Lelouch begrudgingly gave in and opened his eyes.

"Euphie!" The pink haired princess was standing in front of him in a white dress and had a halo above her head. Fitting, as she was the most innocent person Lelouch had known. All of the feelings he had kept locked away came flooding back to him. The dam had burst and he didn't know what he would do if she wasn't actually standing in front of him.

He reached out and gingerly felt her cheek, hoping that something would be there. Euphie gently placed her hands around his wrist, letting him know that she wasn't an illusion.

"But how?"

"I was reincarnated as an Angel after I died."

Lelouch's eyes widened. As much as he loved Euphie, he knew that it would be dangerous to be near an Angel.

"Aren't you going to kill me then?" Lelouch asked, "I am a Devil after all."

Euphemia frowned, "I could never do that, not to my brother."

Lelouch smiled, "Euphie, you really haven't lost your innocence, but you have to understand. A Devil and Angel cannot coexist, it's just not possible."

Lelouch pushed her away and began running. He wanted nothing more than to hug Euphie and tell her how much he missed her, but he knew that they were now too different for something like that. She was an Angel and he was a Devil. He knew that fate did have a punishment in mind for him. He would be able to meet the one person he ever loved, but now, she would be more unattainable than before. Worse than that, it was very likely that he would have to fight her.

He ran until his legs could not carry him anymore. He had never been one to pray to God, and the recent turn of events had made him furious. He knew that churches were dangerous to a Devil, but he didn't care right now. He was too angry to acknowledge the danger as he blew the doors of the church off of their hinges.

"What the fuck was that?" Raynare yelled as she heard a loud crash at the doors. Since she was the only one in the church at the time, as the others were busy with Freed's trap for Issei. She smiled a bit, the boy was so pathetic, not to mention he had one of the weakest Sacred Gears, he really wasn't worth the effort it took to kill him the first time.

Lelouch summoned a huge tornado, tossing pews around like sticks. Before he had returned to the human world, he had discovered that he had an affinity for magic. He had exceptional focus, which had allowed him to master various forms of magic within weeks. In addition, through extensive readings, he had learned how use the special ability of the Murmur Clan.

With his anger, he summoned a lightning strike that obliterated the cross at the end of the room. Wood splintered and as the cross exploded, splinters were flung around the room. Lelouch put up a wall of fire that obliterated any slivers of wood coming at him.

"What do you think you're doing?" Raynare yelled as she saw Lelouch charge up another lighting strike. He turned to her with crazed eyes and for the first time in her life, Raynare was scared. His strength permeated the air and from across the room, she could feel immense power radiating from him. It was apparent from the moment she saw him that he was no ordinary Devil. Beyond that, she could tell that there was a powerful Sacred Gear nearby.

Before she had time to react, he unleashed a stream of lightning from his hands. She felt her heart beat unbelievably fast as electricity coursed through her system. She fell to her knees in pain as she felt her skin being slowly cooked by the heat of the lightning. By now, her heart was beating at a million miles per hour.

Suddenly, it stopped. Raynare thought she was dead for a second, but the fact that she was lying on the hard wood floor of the church signified that she was still alive. Her heart began to slow down, although it was still beating exceptionally fast.

"Why did you stop?" She gasped out.

"You know, I have a favorite saying. The only ones who should kill are those who are prepared to be killed." Lelouch said in a surprisingly calm voice.

"What does that mean?" Raynare snarled.

"That means that I'm prepared to die, but the question is, are you?" Lelouch raised his hand and smirked. He finally would get a chance to test out the power of the Murmur clan.

Raynare's eyes widened in horror as ghostly figures began rising out of the floor. Dozens of glowing figures, many of them with holes in their chests, began cornering the fallen angel. He had discovered that the Murmur clan was able to raise deceased spirits and that was the job they were summoned for the most.

Lelouch chuckled, "Looks like your hands are anything but clean." He observed. He had raised all of the spirits of Raynare's victims, and there were a lot more than he expected.

Raynare tried to back up, but found herself stuck against a wall as she was swarmed by vengeful spirits. Each time one of them touched her, a chill ran up her spine.

She covered her face with her arms and screamed, "Get away! Make it stop!"

Lelouch was impressed. His power seemed to be very effective against her. At heart, it seemed like the tough Raynare was actually a coward. Suddenly, she did something he never expected her to. She fought back. She began hurling spears of light wildly at the apparitions, making many of them disappear. Lelouch noted their weakness against light and decided to experiment more with this power. Before long, she had cleared the room of ghosts.

Lelouch sighed, he was actually pleasantly surprised that she found the courage to fight back. Maybe she would make a decent pawn. However, he felt like her spirit called for a rook. It surprised him that she actually had so much potential.

But before she could become his rook, he would have to reincarnate her. He pointed his right index finger at her chest and focused as much as he could, unleashing an outrageously powerful bolt of lightning at her.

Raynare didn't even see it coming when the bolt blew a hole through her chest. But she felt the intense pain that followed as blood sprayed out of her singed arteries. She collapsed to the floor on her back, trying to admire the painting that adorned the ceiling of the church.

She heard footsteps approaching her and soon found herself face to face with Lelouch. He knew the state she was in. She was down to her last breaths, much he had been a few weeks ago.

"I suppose since you are going to die now, I should introduce myself. I am Lelouch Murmur, formerly Lelouch vi Britannia."

Raynare's eyes widened in surprise. The one who had killed her was the Demon Emperor?

"I have to say, I was just going to leave your body here, but since you impressed me by fighting off those spirits, I'll give you the chance to be my servant." Lelouch said as he twirled a rook between his fingers. For some reason, his comment made Raynare's heart, or whatever was left of it, swell up in pride for impressing him.

"Please." She begged with her last breath. She couldn't bear to be alone, not now. She felt darkness overtake her vision and allowed herself to close her eyes.

Lelouch placed the rook on the part of the chest he had not burned through and created a magic circle.

"I command thee, Ryanare, on my name, Lelouch Murmur, become my servant and once more return thy soul to this land and become a Devil. Thou shall now live a new life with great joy as my rook!" As he finished the incantation, the circle began to glow brightly and the rook inserted itself into her chest.

Sun began to peek though the violet curtains that covered the ten foot panes of glass that made up the windows of the room Raynare was now lying in. The room itself was very bare with only a king sized bed with blue silk sheets, two small drawers next to the bed, and a table in the corner with a chessboard set up. The walls and floor were all made of stone, the gray starkly contrasting with the purple curtains and blue sheets.

Raynare awoke with a sweat covering her brow. Her head was pounding and she could not remember what had happened to her last night. She quickly took in her surroundings and realized that she was not in the church. She instead seemed to be in a castle, although she beyond that, she had no idea where she was. She tried to sit up but was forced back by excruciating pain, causing her to cry out a bit. As she did, she felt someone stirring next to her. She looked over and almost fell out of bed when she realized that she was sleeping next to the man who had killed her yesterday, Lelouch vi Britannia.

She held back a gasp as she realized that Lelouch was naked and still had an arm wrapped around her stomach, using her almost like a pillow. Her naked stomach. It suddenly registered that she was naked as well. She was now much more uncomfortable as he unconsciously pulled her tighter to him, allowing her to feel his now erect member on her leg.

"Did we have sex or something?" She whispered. Not that she would complain. Now that she got a chance to observe his sleeping face up close, she realized that he was ridiculously handsome, although she could not forget the look he had on his face when he turned to her for the first time. It had filled her body with dread and just thinking about it made her shiver.

But still, when he was asleep, he looked far more peaceful, although he face still held traces of worry. He probably had a lot on his mind. She made a move to take his arm off of her, but found her arm held in an iron grip almost immediately as Lelouch opened his eyes and glared at her. He looked at her face for a moment before it registered that she was his servant.

"I'm sorry." He said sheepishly and he released his grip.

Raynare was definitely freaked out at how quickly he had changed emotions. She suddenly realized how Issei felt when she transformed from Yuuma.

But first, she wanted answers, "Do you want to explain what happened last night?"

Lelouch had an annoyed look on his face, "Isn't it obvious? You're my servant now. You should remember that from last night. You looked so proud when I said that I was impressed enough to make you my servant. You know, you really should be proud. You were worth a rook. I only expected you to be a pawn or two but your potential exceeded my expectations."

Ryanare had to blush a little at his compliment, "Thank you, but I want to know why we're both naked."

Lelouch sat up and rubbed the back of his head, "Well you see, in order to heal you, I had to transfer some of my power over to you. The most effective way to do that is to embrace you in the nude, so that's what I did."

"Oh." Raynare said, slightly disappointed that they didn't have sex, although she was glad that she didn't lose her virginity and forgot all about it.

The disappointment in her voice was immediately evident to Lelouch, who smirked internally. She was disappointed that he had only embraced her. Honestly, she was no better than one of his fan girls. Speaking of fan girls, he suddenly realized that he would be late for school soon.

"Well, I'm going to school. I bought you a uniform." He pulled two uniforms out of a drawer and handed one to her.

"What for?"

"Isn't it obvious? You're coming to school with me."

I'm going to warn everyone right now. I'm pretty sure that Lelouch will be paired up with either Akeno or Euphemia, so if you are against incest, I'm telling you ahead of time that there will likely be some later on. For those of you who have come from my recommendation in Survival of the Fittest, I'm going to be focusing on this story more for a while because it's just been easier for me to write this story lately. I'm going to go back and finish Survival of the Fittest, but this is my number one project right now.

I do have a question for big Highschool DxD fans. What Sacred Gear do you think you actually fit Lelouch? I'm only going off of what I know from the anime, so if anyone knows a good Sacred Gear, please help! Please leave any suggestions you can, be it a review or a PM. I would really appreciate any feedback!
