Disclaimer: I do not own Code Geass nor do I own Akame ga kill.

A/N: This is an idea I have been experimenting with for while now and after doing a previous version of it before I feel more satisfied with the second version.

In this crossover I have melded the worlds of Akame ga kill and Code Geass together into one, so expect a lot of changes but otherwise some things will still be the same. This is my first time working with a number of Akame ga kill characters so bear with me, but with that said input and suggestions are welcomed on them as I proceed with this story.

Summary: Wronged by those seeking more power for themselves and with corruption plaguing the Empire with evil everywhere now a young man who had almost being a victim of the most violent power struggle the Empire had ever seen is ready to seek vengeance against those who had tried to have him killed. Raised by skilled assassins to become one of the deadest assassins seeking vengeance he is known to the Empire by one name only: Zero.

Lelouch will make his debut in this chapter and how he ties into the Akame ga kill universe I'll reveal in the coming chapters as Night Raid and other parties try to figure out Zero's true identity. I did use some assassin greed elements in this story as well as introduce a surprising choice for a mentor for Lelouch who some of you might recognize if you have played Elder Scrolls.

As for pairings I have decided on Chelsea and Lelouch, but I am keeping Sayo and Akame handy as potential alternatives should Chelsea don't quite work as planned. I might do Tatsumi and Esdeath through depending on how things turn out for them.

On with the chapter…

Chapter 1

He who walks in silence

It was pass midnight as a full moon was shinning down over the quite estate of a wealthy merchant and trader who lived in an impressive three-story mansion that sat in the center of a lush forest estate which was surrounded by twenty feet tall stone walls to keep trespassers out. Patrolling the grounds closest to the mansion were armed guards wearing plate armor carrying swords and spears for weapons while some carried firearms like rifles. At first glance the mansion was very well defended and secured from anyone who might attempt to infiltrate it, but that was only if the person looking at the security layout was an amateur.

Perched upon one of the trees a distance away from the mansion was an eighteen year old teenager wearing a black cape with a hood. On his face he wore a black polished mask with no visible eyeholes that encased the wearer's head. The rest of his outfit consisted of black robes with plates of armor; made up of several overlapping plates, possessed a gold tint while the rest of it to avoid hindering movement and putting too much weight on the wearer used black leather. Its design was to not only protect vital areas of the wearer, but to ensure free movement and that the metal plates wouldn't create any kind of noise while moving.

Even the black cloak was an important part of the armor as it nearly reached down to his feet just stopping short of his ankles, but it was made up of three layers and not just one. Each layer was longer than the one above it and the longest lower layer was segmented giving the appearance of the wearer to process wings when leaping through air. It was an ingenious design feature to allow the wearer to guide short distances through the air, but it was also useful in slowing down a fall from a high up location.

On his feet he wore a pair of matching black leather boots with metal plates on his shins and his thighs for protection while his hands were covered with black leather gloves while he wore metal armbands around his forearms which included a set of concealed weapons. On his waist was a belt with a dark gray and black sash with a metal belt with a gold emblem of a phoenix taking flight with a sword piecing it. Concealed along each of the wings was a throwing knife, but other tools and weapons were hidden around the waist as well too.

After he finished surveying the grounds ahead the hooded figure silently leapt from the tree while extending his arms allowing the cape to assume a wing like formation allowing the teenager to guide softly to the ground near the rear of the mansion. A pair of guards was in deep conversation as they continued their patrol having failed to notice an intruder approaching the mansion. Moving silently the infiltrator scanned for any signs of any other guards who might have been watching from one of the windows, but when he saw none the hooded teenager began scaling the side of the mansion making his way to the roof.

'Are these fools that confident that no one could get this far in?' The masked man thought as he reached the roof of the mansion. He stealthily moved across the roof while mindful to keep to the shadows while blending in with the rest of the rooftop to avoid being spotted from the ground.

Reaching another side of the mansion the hooded infiltrator climbed down until he came to a balcony leading into the master bedroom where his target laid. Using a small metal pick from his belt the masked man quietly, but carefully undid the lock before slowly opening the door to creep inside. The interior of the master bedroom was big and spacious, which was typical for wealthy merchants of his target's reputation and profession. What was also predictable of a merchant known for bribing the guardsmen, the courts and other influential parties was how predictable he was in indulging himself in a number of hedonistic pleasures such as having two women share his bed with him as he laid in the middle.

'How predictable…does his wife know about it?' The teenager thought gazing on the scene with a look of disgust hidden behind his mask.

On one hand even if his wife knew anything about it she probably couldn't do anything about it since her so-called husband could easily use his influence and wealth to turn her life and those of her family into a living hell. The man before him was on the surface a generous and very wealthy merchant who owned and operated a number of trading caravans and shipping operations for the Empire. In private it was almost what was typical for those with wealth and status today.

The truth was that the man before him aside from his legitimate operations ran a second more shadier business of transporting illegal goods, and weapons for black market purchases while also involved in the selling of slaves to nobles, factories, farms and some hellish locations. That was just the tip of the iceberg as those who were unfortunate enough to be young and beautiful were forced into brothels he had in operation in the capital. Even worse for some who ended up his own personal slaves, although thankfully the bedding covered enough of the three but he could see the bruises and signs of cuts on their arms and necks.

The masked man, Lelouch Lamperouge only became more determined to end his life.

But before that Lelouch had a job to do so silently going to one side of the room Lelouch began carefully investigating the merchant's desk. Noticing a cabinet had a lock on it Lelouch picked it before opening it. Using the moonlight as a source of light to glance at some of the documents inside Lelouch quietly placed them within a bag he carried on the backside of his waist.

With that task complete Lelouch crept over to the side of the bed Lelouch was grateful that the man was sleeping on his back and with his mouth slightly open. Drawing a special tool from his belt he extended a small metal stick that reached out across the bed. Once he held its end over the merchant's mouth he pushed a button as a small amount of clear liquid was released dripping into the man's mouth.

Lelouch was careful not to let too much drip in at a time, which could cause the man to gag thus waking him up. Once he saw the man swallow enough of it he put the device away and quietly went out the same way he came, but not before leaving his calling card which was a white thick piece of paper folded over so it could stand on the nightstand by the bedside with a black printed emblem of a phoenix taking flight with a sword through it.

'He'll be dead in a couple minutes.' Lelouch thought with a smile of triumph under his mask.

The poison he had given the sleeping man was harvested at great personal risk from a deadly danger beast that uses such poison to kill enemies and prey before consuming them. It first causes the body's motor controls to become paralyzed to prevent escape and then swelling in the throat and air passages happen minutes later causing the victim to suffocate and die. The poison itself, although it was highly effectively, was extremely risky to obtain. However for tasks like these it made carrying out assassinations against his targets much easier.

Unless the poison was treated at the moment of infection the target was dead within five minutes.

As Lelouch hurried across the rooftops not wishing to be around if the man's death somehow awoke his unwilling bedmates which could lead to the guards being alerted to the presence of an assassin. Even though he hurried he was cautious and used stealth to keep to the shadows so the guards patrolling the grounds around the mansion would not see him. Reaching the rear of the estate Lelouch waited until he saw no guards in the area or anyone watching the rooftop, so with one leap he opened his cloak again using the wing-like attachments of his tipple-layered cloak to guide across the air reaching the base of the forest that surrounded the estate.

Taking to the trees Lelouch used to them to avoid detection with the darkness providing additional cover. It didn't take long for Lelouch to reach the wall upon which he jumped guiding through the air once more allowing him to make a clean get away. He might have escaped the estate after breaking in and fleeing undetected, but he stayed alert until he returned to base. He moved quickly through the forest working to put as much distance as possible between him and the mansion.

But unknown to him at that moment another group of assassins had begun an attack on the mansion.

Unaware of the fact that their boss was likely dying of poison at that moment the guards who protected the mansion rallied together to defend it from a group of five people. Even through the guards outnumbered them, but in terms of skill and weapons they were hopelessly outclassed. Even the guards who were armed with rifles couldn't charge the tide of battle as they were getting slaughtered by the dozens within mere minutes of the battle beginning. Outside a girl wearing pink armed with a large rifle-like weapon was picking off enemies who either attempted to attack them or those attempting to flee. Another was wearing full armor armed with a spear who was engaging the guards in melee combat before swiftly decapitating them. Then another member with green hair armed with wires for weapons was also adding his two comrades in making short work of the guards who tried in vain to stop them.

During the battle the last two members, both of them female infiltrated the mansion swiftly killing any guard unfortunate enough to cross their path cutting a bloody path to the master bedroom. One of them was older than the two armed with a very large pair of scissors wearing a revealing outfit that matched the color of her purple hair and eyes along with a pair of glasses. Her comrade seemed younger with long black hair that reached down pass her waist with red eyes wearing a black outfit with a red tie, a skirt and matching shoes armed with a katana-like weapon with a red hilt.

One guard became another poor victim to Sheele's Teigu as she literally cut the man in two with Extase. Akame led the charge as the red-eyed assassin kicked open the doors to the master bedroom where they saw their target lying motionless in his bed while the two women who had been with him prior had been awakened by the sound of the battle outside which had prompted them to take refuge inside the closet fearing for their lives. Fortunately for them neither of them were a target for Akame and Sheele, but the fact their real target wasn't moving puzzled them until Akame approached him to check his pulse.

"He's dead, but," Akame said in an emotionless tone before noticing the swelling around his neck and the blood coming out of his mouth and nose. "I recognize this…he was poisoned with Chaurus venom. This man died not too long ago…his body is still warm."

"But isn't getting Chaurus venom very difficult?" Sheele asked titling her head to one side to look around the room. Knowing how difficult getting your hands on such potent poison it was quickly ruled out the two women hiding in the closet had done the deed, but Akame looked to the nightstand and saw the answer.

"It was Zero…again." Akame said picking up the calling card he left behind.

"Zero, but how…I thought Leone was covering the rear?"

"He must have slipped away before we began our attack." Akame answered calmly. "The mission is a failure, but the target is dead."

"Mine isn't going to take this well that Zero has beaten us to another target." Sheele said before she and Akame left the room.

As a group, Night Raid carried out assassinations for clients after doing a background check on both the target and the client, but in truth they carried out assassinations and missions for the Revolutionary Army that was rising up in opposition to the corrupt Empire being controlled through manipulation of the child Emperor by the Prime Minister.

The mysterious assassin Zero who began appearing over a year ago wasn't competing against them per sec, but rather there were times in which the two shared the same targets. The first time was when she and Mine had been sent to kill a target who was a high profile target who was a member of the nobility, but was a corrupt official within the Empire who accepted bribes and usually used his post to help falsely accuses and imprison innocent people who just happened to make the mistake of making an enemy of someone who had connections.

But the man was paranoid and was constantly in the companion of his bodyguards and his home was surprisingly well defended, so during an attempt to assassinate him during a festival Mine was preparing to shoot him from a safe distance. However before she had a chance the target had joined with a large group of festival attendees having been led away and memorized by a beautiful woman, but in one moment of blissful carelessness a person wearing a black cloak came and slashed his throat open with a concealed blade of some kind.

It had happened so quickly and suddenly it took the man and his guards a full minute to realize what happened before their target bled to death and died before the festival collapsed into chaos. Yet before anyone realized what happened Zero had come, cut open the man's throat while at the same time slipping his calling card into his pocket to be found later and then slipped away like a phantom before anyone realized what had happened. It was Zero's most public assassination and yet he got away clean with no one seeing him. In fact he had obtained something of a mythical status within the Empire as the assassin with no identity giving him a number of nicknames such as the phantom assassin, the glimmer man or the one name that has become the one that most have recognized him with.

Zero the assassin who leaves zero witnesses behind, but none of which he had never killed. No this came from the fact that no one except for possibly his targets might have seen him before meeting their end.

In fact his existence for the most part was questioned because of the lack of witnesses and evidence of his existence. No one was even sure if Zero was even a man, but still unlike Night Raid the Empire had virtually nothing on Zero, so even when they posted a wanted poster of him all they could put was his emblem which was always upon every calling card he leaves behind at each assassination he carries out.

"I don't know how she'll take it, but I think something will need to be done. It's becoming inconvenient that he kills some of our targets before we get to them."

The sun was beginning to rise when Lelouch finally made his way back to the place he called home. He lived a fair distance most towns near the capital so the area was remote enough, but it wasn't enough for the type of home he needed. Coming to a hole in the side of the mountain Lelouch stood at the mouth of the deep pit which descended deep underground. The rocks along its walls were polished smooth with virtually no way of climbing down let alone being able to climb back up, but without fear he leapt into the hole and began free falling into the dark underground below.

Using his cloak to slow his descendent until Lelouch managed to land inside of a cave one hundred feet from the top of the chasm where a tunnel led further underground while behind him the pit had at least two hundred feet more before the bottom. His mask allowed him to see the path before him and so he continued down it for a time navigating a maze of tunnels, but thankfully he had been taught to memorize the pathway so he could avoid getting lost.

Danger Beasts of the more subterranean type inhabit the underground area, but thankfully they never poised to be a problem due to both the fact the hideout was very well fortified and protected against such attacks while it had special means of repelling them. Lelouch had a special repellent provided to him to ensure his safe passage through the tunnels. Finally after a twenty minute walk through dark underground tunnels Lelouch came to a wall craving at the end of a winding tunnel.

It had read markings with people around what appeared to be the symbol of a hand.

Upon laying his hand within the hand mark he heard the door special directly into his mind.

"What is the music of life?" The door asked with a slow and raspy voice.

"Silence, my brother."

"Welcome home!" The door replied before it began to open by the wall sinking into the ground. Ahead at least three more stone slabs slid back allowing Lelouch entrance before two heavy metal doors were withdrawn into the ground allowing Lelouch to approach a pair of heavy metal doors. Pushing them open Lelouch entered a vast underground chamber that looked more like the interior of a castle with stone bricks lining the floors, ceiling and walls with stone pillars linking the chamber. On the ground was a red carpet with a black hand imprinted upon it. Upon the pillars and walls were lit torches upon metal scones that kept the chamber well lit making it a welcomed contrast to the dark and cold caves outside. Off to the side was a large pool filled with water that was fed through an opening through the ceiling creating an indoor waterfall effect providing a source of fresh water, but Lelouch knew it was one of many where the water came from a different source.

Taking a deep breath following the removal of his mask Lelouch wiped some sweat off his forehead as his black hair hung freely. As much as he enjoyed the mask some times, but after a long mission he was glad to finally take it off once he had returned home.

"Welcome home Lelouch." Said a man wearing black robes complete with a hood that covered his head, but his face could still be seen. He had a light complexion with blue eyes and a stern expression upon his face, but Lelouch knew the man enough that he could easily hide his emotions well and appear happy or angry without changing the tone in his voice.

"Mission accomplished." Lelouch answered to his friend and mentor Lucien Lachance.

"Oh I know, but it seems once again you and Night Raid has intersected once more."

"I assume it happened sometime after I left?" Lelouch asked with an annoyed tone to his voice.

"I wouldn't worry about it, but did you deposit the documents you recovered at the dead drop?"

"Of course I did, but I made sure no one was around when I made the delivery."

"I did not doubt you for a moment, but you must never grow clearly nor must you never relax your guard. That is what it means to be an assassin of the Black Hand."

"I know," Lelouch said before letting out a yawn. "If you don't mind I would like to clean up and get some sleep."

"Of course we can talk once you are fully rested."

The following day back at the estate Lelouch had visited to kill his target before Night Raid hit it. It was about noon when a young man with brown hair and green eyes wearing the black and white uniform associated with those of the Imperial Garrison. His uniform came complete with an armored breastplate and armor on his shoulders was approaching the front door of the mansion. Suzaku Kururugi was approaching the mansion while the surroundings near the front look as if a warzone had happened. Of course Suzaku had a number of questions on his mind, but probably the most common he had on his mind was.

"Follow me Suzaku we shall find the ones responsible for this."

Those words came from his very energetic and overzealous partner and superior who like him wore the same uniform as he did, but hers was more of a female variant with a one-piece uniform top with long sleeves complete with a skirt and long white thigh-high socks. She had long light brown hair styled into a long-ponytail that reached pass her waist with matching eyes and almost never fading smile.

When not in the presence of those who were evil in the mind of Seryu Ubiquitous at least, but Suzaku wondered which superior did he anger to get assigned to the woman who was his superior?

"I am sure we will." Suzaku said since trying to argue otherwise would be pointless.

Following Seryu was a small dog-like creature that seemed quite unusual, but very few realized he was in fact a living Teigu called Magical Beast Transformation: Hekatonkheires. Seryu on the other hand affectionately called the dog-like creature Koro treating the living organic Teigu like a pet and attack hound all at once.

'I pray she doesn't end up killing anyone this time for a minor offense.' Suzaku thought as he had the unfortunate task of trying to be Seryu voice of reason, especially when she was in one of her dealing out justice sprees as she calls it. Suzaku called it Koro enjoying a one-sided feeding frenzy as the tiny dog would grow to gigantic size to devour anything unfortunate enough to be caught by it.

Entering the mansion Seryu would question the butler who was among the few people to be left alive after last's night battle which left all of the guards dead along with most of the servants who had attempted to fight back against Night Raid when they invaded. However it wasn't discovered until later that Zero had once again beaten them to the punch and killed Night Raid's target with poison. Even the women he had in bed with him didn't know when he had died until the sounds of combat during Night Raid's attack woke them up.

It was only after that did they realize the man was dead.

Workers and hired help from the nearby town were busy helping to clear away the bodies for burial outside, but Suzaku had wished they could have left them lie as they were so they could have studied the crime scene where the chances of them finding evidence was higher. Now it had been ruined now, but on one hand he wondered if it would have made a difference anyway.

'We know a lot about Night Raid and some of its members, but Zero…we know nothing about him.' Suzaku thought because unlike Night Raid who was composed of a number of skilled and powerful combatants with Akame a once famous imperial assassin and former imperial soldier Bulat who earned the nickname 100 Man-Slayer Bulat for his prowess. Of course those were two of its famous members, but there were others and their leader to consider too. Either way Night Raid was formidable with little success towards any information leading to their headquarters or their capture.

It was a very different story with Zero.

No witnesses and no evidence save for his calling card he leaves at the site of each murder. No one has actually seen Zero, so his existence has been called into question more than once. People weren't even sure if he was a man or a woman because so little information on the masked assassin existed. Unlike Night Raid the masked assassin would always infiltrate his target's home without alerting the guards or even the target to his presence until long after the deed was done. It did seem through that Night Raid and Zero did not collaborate with one another with what happened at the estate last night being one of a very small few of such cases.

Even when he committed an assassination on a target out in a crowd of people enjoying a festival no one recalled seeing him, but that made the fact clear in terms of sheath and infiltration Zero had no equal.

Suzaku had finished questioning the girls who had been with the man when he died, although he detested men who engaged in such illicit acts especially when he could tell the women he had were not willingly with him judging from how they seemed to care very little for his demise. In fact he noticed traces of them being glad at his demise even though they were trying to hide it out of fear of retribution. Suzaku didn't inquire nor would he make a mention of this in his report.

'They have been through enough already.'

This was one of the things he disliked about his job at times, although he had joined it with the intention of changing the Empire from within for the better. He realized what an uphill battle he was facing upon seeing the number of corrupt officials, merchants and nobles who abused their power for various reasons. Cases of women being threatened and forced into illicit activities with a nobleman and a merchant were unfortunately common in the capital.

He tried to do something about it, but unfortunately he failed to consider that those corrupt forces existed in the Imperial Garrison and probably higher up as well too.

'I'll need to go higher before I can try to make any chances, but I guess that would depend if I can stay on Seryu's good side.'

Suzaku thought after he finished questioning the girls that he observed his superior questioning another survivor of the attack. Fortunately Seryu wasn't corrupt, but unfortunately she was far too overzealous about punishing those who are in her view evil that those who were against the Empire were evil while those with it regardless if they were corrupt or not were good. A simple black and white view of the world, which combined with how overzealous she was in punishing criminals and assassins made Seryu extremely dangerous.

Thankfully Suzaku learned to adapt and he has tried and succeeded once or twice at being the young woman's voice of reason. On a scale of one out of ten he succeeded three out of ten times when he convinced Seryu to follow a criminal to his hideout instead of outright killing them on the spot to get the entire gang instead of just one member.

Other times it was mostly hit or miss through.

"Suzaku did you get any useful information?" Seryu asked cheerfully.

"Not much, but its Zero's handily work as the poison used is indeed Chaurus Poison." Suzaku answered putting away his notepad. Chaurus Poison was a preferred favorite of Zero as he coated all of his weapons with it apparently so if the initial strike didn't kill them the poison would.

"Zero and Night Raid will not escape justice forever!" Seryu declared proudly, but Suzaku noticed the hints of frustration in voice which was a common feeling shared among officers who had tried their hand at investigating Zero.

Yet all of them always turned up empty handed with nothing to show for their efforts so they abandon the case leading it to be passed from one officer to another until now it was passed onto Seryu and by extension him.

'The only way we'll get Zero is if he or she slips up, but…that doesn't seem likely to happen any time soon.' Suzaku thought.

Later that afternoon at the hidden base concealed within a wide cavity within a mountain which provided perfect cover from airborne search parties while making it the ideal location for a natural fortress with castle walls and a central tower in the middle all built below the mountain that covered their headquarters. Standing 10 km from the capital in the mountains range where danger beasts roamed and there were very few villages and settlements in the area, which only made it more ideal as a base of operations for Night Raid.

After resting from last night's mission the members of Night Raid including Akame, Sheele, Mine and the rest of their group was gathered in the main hall for a meeting regarding last night's mission and Zero with their leader. She was probably one of the oldest of the group with white-silvery hair cut short, which if not for her feminine appearance she could easily be mistaken for a guy. She had a purple eye while the other she lost a long time ago, but it was covered by an eye patch while she wore a black suit with a mechanical right arm.

"I am so pissed that Zero interfered in another job AGAIN." Mine shouted voicing her displeasure. As the pink haired girl sat on a chair with her arms crossed across her chest.

"Hey how are we supposed to know Zero nailed the target?" Another member of their group said, a young man with short green hair wearing a white shirt with a green jacket matching his hair and eyes with goggles worn on top of his head.

"There is no question Zero is good at what he does Lubbock. We haven't seen an assassin of his caliber in years with our little Akame being close to him." The oldest male among them, Bulat said. He had gel-slick hair styled into unique hair style while he wore white pants and a black shirt with green armor on it.

"Yet we know so little about him. Even HQ knows nothing about him…or her." Their leader Najenda mused while in deep thought. "We know Zero is against the Empire, but the reason why he or she hasn't joined with the Revolutionary Army raises a lot of questions."

"You think he is an enemy then just getting rid of people who might be in his way?" Mine asked while her partner Sheele remained quiet as did Akame.

"No I doubt that, but regardless we need more information on Zero. So I want to include seeking information on Zero or information that might help us find him or at least try to comprehend his motives. If we can learn that much it could help us in discovering his identity and finding the man…or woman."

"That is a tall order." Leone noted.

"I know, but I am feel annoyed a few of our jobs have crossed paths with Zero without realizing it so I think we should start there and find out if there were anyone else who might have wanted those targets dead."

"Now that is going to be even harder. Do you remember the lottery we had to hold just for that one guy killed at the festival by Zero because so many people wanted him dead were trying to hire us?" Leone said with a matter of fact tone.

"Yes I know, but still we need to start somewhere."

Deep within the mountains where Lelouch hid the young man was an awake and already training his body to keep it in prime condition wearing a black shirt and pants while doing pushups in the training room of the underground hideout. He remembered a time that years ago he couldn't do a single push-up let alone run very far, so it was a marvel at how far he had come.

But a burning need for vengeance has a way of being a good motivator.

He wouldn't be here if it wasn't for Lucien. The man who saved his life and the man who trained him and raised him as an assassin and a fighter so he could take vengeance and reclaim what belonged to him. But that was secondary as he wanted vengeance against those who had tried to murder him and his sister years ago with his ultimate target being the man who masterminded the whole thing.

The Prime Minister was Lelouch's target yet at the same he was his mortal enemy.

'Soon the time will come when I'll cut out your throat Honest.' Lelouch thought as his purple eyes burned with rage.

A/N: Nunnally and Sayoko will be introduced in the next chapter, so tell me what you guys think? I am going to take care of one of my other fics before returning to this one. Because I do want to be sure I am getting the characters right before I proceed too far ahead and find out I messed up with them lol. But I am confident in the story itself and I do got a lot of ideas for it.

Thank you in advance for your reviews and input.
