A/N: Special thanks to AnubisGundam0 for doing beta work and proofreading of this chapter as well as ideas and suggestions for this crossover. I'll save the rest of the author note for the end of the chapter where I'll explain some details about the story and planned pairings so far, but this story will not involve a harem of any kind for Lelouch.

Summary: Lelouch has been given an unexpected offer which could provide him with more than enough funds and resources to begin his campaign to topple his father's Empire, but as with any deal there is a catch and Lelouch must enter the First Dead or Alive Tournament to eliminate a dangerous foe. Yet this is only the start of an unexpected chain of events Lelouch could not have foreseen.

For five years he spent time within a hidden village inhabited by formidable shinobi he was secretly trained by one of their own against their wishes and must apply that training, but will it be enough for the trials that will lie ahead for Lelouch?

Chapter 1

From Nothing I Arise

(March 10 2017 A.T.B.)

It was pass midnight around the Port of Yokohama in Tokyo Bay where shipping containers were being off loaded filled with illegal goods including narcotics to be sold on the streets after the contents were organized and disturbed to various dealers around Area 11, the country that had been once Japan. It was seven years ago that the Holy Britannian Empire declared war on the small island nation of Japan, defeating it only after a single month of fighting.

Officially the war had ended when Japan's last Prime Minister Genbu Kururugi committed suicide in order to stop the military when they called for a do or die resistance, however there were rumors questioning that claim as some realized that if the Europia United and Chinese Federation got involved the resulting three-way war could have destroyed Japan in the crossfire with the other superpowers getting involved solely for the sake of Japan's Sakuradite Mines as it provided seventy percent of the world's total supply.

This was avoided thanks to the well planned political maneuvering following the end of the war with Japan, and Britannia chose one of the world's most wealth industrialists, Fame Douglas, who was the CEO of Dead or Alive Tournament Executive Committee (DOATEC) which made its wealth as a international weapons research and development company. It had its hand in other business ventures as well including international transport and infrastructure and more thanks to its various subsidiaries under it. Despite mixed relations between the counties of the world, Fame was able to successfully run his business and make deals with all three superpowers while maintaining a stance on neutrality among the nations which his companies in the nations of the three different superpowers could develop and research weapons for their home country they were established in and could not share said research with other countries while it sold general arms to everyone else to avoid alienating its business partners and customers in said country.

It was extremely difficult especially given the fact Britannia and the Europia United have been locked in conflict for years, but Fame's company has at times acted as a neutral third party in-between them helping with negotiating between the two countries usually for prisoner exchanges and rarely cease-fires with individual member nations of the EU.

Due to this and the fact Fame Douglas had connections to many influential individuals and leaders within the three superpowers he was chosen to ensure even distribution of Sakuradite from Japan on Britannia's behalf and even offered them a little more than Japan had done in the past to pacify the remaining two superpowers into seeking to liberate the Sakuradite Mines from Britannia.

Thanks to this DOATEC gained more influence and wealth thanks to this arrangement, but there were some within the company's higher ranks that believed a different approach to their business was needed.

Now seven years into Britannia's conquest of the island nation its new occupational government due to its encouraged policy of discrimination against non-Britannians opened the door for criminals to take advantage of such a policy where the police were only concerned generally for the welfare of Britannians, rather than the natives not born Britannian.

The drug dealers on the harbor operated with that in mind, selling most of their product to the local populace which had been renamed 'Elevens' instead of Japanese as a shameful title of their defeat.

"Alright people let's get the stuff to Kyoto so we can get it distributed." One of the men ordered. He was a bald headed man wearing a heavy blue jacket with jeans and blue button up shirt underneath. "Come on let's move it we don't have all night."

"What are you so worried about? The cops don't bother us here!"

As the men began chattering amongst one another, a man, another thug in their employ, was bringing out the last box containing their smuggled product out of a shipping container when suddenly someone or something attacked him. He barely had a chance to call out for help, but the sound of glass shattering from within the box he dropped drew the attention of his fellow criminals.

"Hey Stan!"

There was no response as two of the twenty man crew went to investigate what happened to Stan.

They stopped at the box full of broken glass, but they found no sign of their missing companion.

"Where the fuck are you Stan?"

"You better not be fucking around again?" Another man called out, but after turning around he saw his companion who had been walking with him was gone.

"What the fuck," The man said beginning to panic, but as he rushed by another shipping container to rejoin his compatriots a black gloved fist backhanded him in the face knocking him out.

Seventeen men were left and no one realized three of their own had vanished. Watching them from atop a stack of shipping containers near the end of the harbor was a man wearing black with a cape and a black spiky mask. The wearer was impressed by his new suit as it fit him so perfectly it felt like a second skin. He had been trying for some time to find body armor he could wear, but nothing even compared to the customized body armor he was wearing now that afforded him better durability than ordinary armor and kevlar body armor.

Even the mask he wore while appearing polished and faceless on the surface concealed an array of devices and gadgets integrated within. His view of the criminals was magnified through his mask allowing him to see them clearly at a distance as if he was standing only five feet away and directional microphone built into his mask allowed him to eavesdrop on their conversation.

"Come on keep it moving, I want us out of here within the hour." The leader of the narcotics smugglers ordered having not noticed three of his men were missing.

Under the mask the young seventeen year old smiled, but his satisfaction went far deeper. For Lelouch vi Britannia it felt good to be the predator instead of a weak and helpless child he used to be.

This suit is amazing…I can move so freely and easily, but yet it has more protection than any typical body armor.

Lelouch couldn't help, but be amazed at his new outfit which not only served to hide his identity but it allowed for him to create an intimidating persona. His armor was state of the art provided to him by an unexpected ally despite his initial reservations, but after testing out the new armor the young man could help but feel very pleased with the results. His armor used a variety of new technologies in its construction and in the gadgets and weapons he carried on his belt.

Taking advantage of the criminals being unaware of his presence, he used this opportunity as a way to field test out his new armor and weapons, it also made it easier that Lelouch had strong disdain of drug dealers.

Unhooking what appeared to be a small boxed shaped metallic object from his belt on his left side near his back, Lelouch depressed a button on the side of the case and the spring loaded mechanism unfolded it into an odd-shaped rifle with a long barrel and a pump-action like trigger with a countdown timer and small knobs to adjust the time. Lelouch set the timer to one minute and twenty seconds before taking aim with the gun. Using his mask's magnification feature to confirm his hits he fired specialized rounds that upon impact released a sticky highly explosive substance that adhered to any surface. The rear of the bullet that housed a timer and detonator that was synchronized with the other bombs Lelouch fired from the gun, an infrared light visible only through his visor indicating that it was armed.

He planted two bombs on the semi-truck being loaded with the drugs, landing one on the gas tank and one on the left open container door in the rear. Then he planted another two on the boxes of cargo they were still offloading but chose boxes they would not reach for at least a minute or two and then finally he landed three more on the overhead lamps providing lighting for most of the area.

"A ninja understands that invisibility is a matter of patience and agility."

Lelouch recalled the lecture of the man who trained him, denying the wishes of the ninja clan he belonged to. As Lelouch stealthily descended from his perch to get closer to the men before the bombs went off within the next minute and twenty seconds he found himself recalling the lessons of the man who was part of a special sect of the village he and his younger sister spent five years at until the newly christened Area 11 was more hospitable for them, before reinserting them back into society under the care of his mother's old allies would be easier.

Unlike his time spent at Kururugi Shrine when he lived under the care of Genbu Kururugi, his time at the hidden village he was smuggled to for safe keeping until it was right for Lelouch to rejoin society, while steps were ensured to keep him from knowing where he was and how to get back. His sister's treatment was much kinder and better in comparison as many in the village felt that any ill treatment for a crippled young girl was dishonorable, but Lelouch on the other hand.

He wasn't beaten almost every day by local children like before, but he wasn't exactly welcomed with open arms given that he was a mouthy exiled prince of the country that just conquered theirs.

Soon after he met the man who would become his instructor found Lelouch attempting late night physical training having realized his physical limitations and if he wanted to fulfill the vow he made when he and the first friend he made separated.

"You are so frail, but yet your rage fuels your desire for power doesn't it?"

An eleven year old Lelouch looked over his shoulder at a man in his late forties, with his hair beginning to turn gray wearing a wooden mask and wore dark clothing including an embroidered dark haori which was a sign of his status as a ninja master.

Lelouch said nothing, but he eyed the masked man with distrust and yet the rage was clearly seen in his eyes.

"They believe you are dangerous, but you are hardly so when you're so weak."

"What of it?" Lelouch spat bitterly before his bruised and bloody fists tightened in growing anger, his blood boiling. "I want…I vow to annihilate Britannia for what that man did to me and Nunnally, including allowing my mother to die!"

"The Britannian Emperor, I see…he sent you here to die so that when the invasion takes place the death of a royal family member is sure to provide good motivation for their troops." The masked shinobi's calculating gaze locked eyes with Lelouch briefly before saying. "I can offer you a chance to become someone who can fight an army and become invisible to your enemies, to strike from the shadows like a ghost. Not to mention that is but a taste of what I can offer you, but only if your body becomes stronger."

"Isn't it against the laws of your village to train an outsider?"

"It is, but given that you will be staying in the village for awhile under our protection, you will have plenty of time on your hands. Exercise and training to better your body, they will not mind, so do so until you show me you have the strength of body needed and perhaps I'll train you as a ninja who will not be bound by any code, or laws because you are an outsider."

"I see so you are exploiting a loophole, and because your clan has decided not to act against the Britannian occupation, which I know there are people not happy about it." Lelouch said as he wiped blood away from his lip. "Knowing I'll take revenge on Britannia, but I lack the strength to make it happen, you wish for me to do it."

"Yes, but be warned boy I will not be gentle in your training, and if you cry out in pain then I'll only push you harder."

Lelouch considered his choices for a moment, although he didn't doubt that the masked man before him had other motives for training him, their mutual desire to see Britannia fall united them. He gazed down at his bloodied hands which were the result of punching a log in frustration earlier due to the cold realization that his frail body would make it unlikely he could do much other than possibly command a rebellion from the rear, his formidable mind his only asset, even so…

"I accept…"

Tonight I'll find out if the hell I endured was worth it.

A second later the bombs went off causing chaos, blowing up the truck and most of the drugs the pressure wave knocking some of the thugs backwards before they realized what happened. To add to the confusion, Lelouch had beforehand tossed smoke bombs into the air landing and detonating a second after the sticky bombs went off blanketing the area in a cloud of smoke. His mask was equipped with specialized vision enhancements and sensors such as light amplification, ultraviolet and infrared vision Lelouch didn't require them to deal with this lot, lost in the smoke cloud.

His training enabled him to enhance his natural senses greatly beyond their normal range enabling, him to easily locate the seventeen men within the smoke cloud before skillfully and quickly using hand-to-hand combat techniques to dispatch them. He withdrew a shuriken from his belt with his free hand before hurling it at one of the men lost in the smoke cloud cutting into his throat and embedding itself there. Using one of the men as a human shield as another of the drug smugglers fired their gun into the smoke in the direction of the sound.

The drug dealer had only succeeded in killing one of his own allowing Lelouch to slip away back into the cloud of smoke attacking like a phantom from beyond.

When the smoke finally cleared all of the drug smugglers were on the ground dead with their necks having been snapped or stabbed in the throat with a throwing knife or shuriken, or there were cases where Lelouch used their panic to trick them into gunning down their own.

Lelouch was gone by the time the smoke cleared disappearing like a phantom into the night, but this was thanks to a Ninpo (ninja arts) technique he had picked up during his training after his body had become strong enough for the promised training. It was a fairly common technique among shinobi of the hidden villages, but it was one of his particular favorites.

The young man was running through the night keeping to the shadows of the various warehouses along the water front and avoiding the street lamps and lights being emitted by the nearby buildings. The former prince of Britannia felt quite pleased with himself. Even though those criminals were lowly thugs who deserved what Lelouch did to them and not much of a challenge for him in terms of combat skill, but they were successful in helping him test his new armor and putting it through its paces.

It was so easy…the old me wasn't capable of this.

With his frail body he had no chance of pulling off what he did tonight, but thanks to the pain he endured during the training to strengthen his body before being secretly trained in the village's ninjutsu arts he was capable of much more.

I am still lacking two things though…

His teacher had driven that point home with tales of a growing prodigy in the Hayabusa Clan, an allied ninja clan of the village Lelouch was hiding in, referring to him as the strongest ninja their clan had produced, possibly surpassing the village's own intended heir.

The other ninpo techniques he was told about including powerful ones exclusive to certain ninja families and clans further clarified this for the former prince.

Of course that is assuming he would fight fairly.

Being that he was wasn't raised as a ninja and was taught only combat skills and ninpo techniques Lelouch was not bound by the usual ninja laws and codes as least as far as his mentor was concerned.

Even with his skills and stronger body, Lelouch was hardly capable of bringing down his father's own Empire, an Empire that controlled one-third of the entire world, not without resources and manpower. In fact when he attempted to create his own combat outfit to compliment his needs to hide his identity and to give him some protection during a fight he used his winnings from underground chess matches to obtain what he needed. However obtaining some of the components he wanted for his originally intended combat uniform was surprisingly more difficult and couldn't be done without raising suspicion.

Until he was visited by the most unlikely person imaginable with an offer Lelouch couldn't refuse. He questioned his motives knowing there was something else despite his claims, but knowing it could possibly take years for him to amass the needed resources on his own, he accepted.

Reaching the edge of the harbor and being a safe distance away from where the drug smugglers location, Lelouch leapt off of the top of the warehouse facing the ocean using his cape to guide over the water until he landed on a black aerodynamic object that had been hovering a few inches off the water. To passing casual observer there was nothing out there except for the city lights along the shore of the Tokyo Bay.

Lelouch's mask outlined a customized aircraft that was a prototype aircraft using new technology being developed by the Holy Britannian Empire dubbed a FLOAT system to allow anti-gravity capabilities and flight. It was only a prototype possessing a miniaturized version of the system which his sponsor had obtained to test on the repurposed prototype he was using, including constructed with advanced stealth systems. It had a fifty feet wing span which could fold into different configurations for landing or for hovering stationary attack mode using its arsenal of weapons.

It was thirty feet in length and was designed to be operated by one person, but it could carry a second passenger in a seat behind the pilot.

Once inside the cockpit the canopy window slid shut, sealing Lelouch inside as the windows were polarized, but he could see everything around him just fine as the cockpit could use display images from a variety of sensors like his mask to illuminate the world in different ways for him. The cockpit canopy was made of a transparent ceramic polymer making it quite durable designed able to withstand punishment especially when the plane was in operation.

It was armored with plates of black armor and designed as experimental test bed to develop new Stealth Planes that could use FLOAT technology among testing other functionaries such planes could serve if they go beyond the prototype stage.

Lelouch took control of the plane as a wireless connection between his mask and the plane's computer displayed the cockpit's HUD directly on his visor. The cockpit possessed dashboard diagnostics including the usual features including an advance sensory package including infrared, radar and sonar (when converted to submersible mode). It had navigation and communication systems and features needed for the craft's second mode of transportation.

Flying across the bay at a low altitude Lelouch switched the craft over to its secondary mode which was a submersible mode as it dove into the water heading for the bottom. The engines switched over to underwater propulsion hydro jets driven by centrifugal pumps, while its engines and exhaust for flight were sealed by watertight covers and slides that locked into place to prevent them from being flooded by salt-water.

The wings altered their configuration to compensate and allow for better maneuverability underwater as Lelouch steered the plane through the murky depths of the waters of Tokyo Bay.

And to think this craft is capable of remote control and autonomous functionality. Lelouch mused.

The prototype craft had an onboard AI system and it could be controlled remotely by Lelouch to either summon the plane to his location or to carry out certain actions for him. Such a feature Lelouch knew would come in handy and it was being intended to use as an escape craft.

Because for all of the weapons and gear he was being given there was a catch as expected.

The plane began traveling through a hidden underwater tunnel that led Lelouch under the city of Tokyo, as he was heading for an underground hanger that had been secretly prepared for his new mode of transportation. It was quite a distance from the harbor, but its twisting maze-like passageways would make it very difficult for anyone else to use. Emerging from the water at the end Lelouch surfaced the plane out of the water as he switched back to flight mode and hovering above a large circular platform before landing it on.

As the engine shut down Lelouch was approached by a man in a gray business suit and red tie. He was a dark-skinned, middle-aged man with board shoulders. His black hair was short, combed back, and was graying in strips along the side of his head. He also sports a neatly-trimmed beard and dark eyes.

As Lelouch disembarked the plane the older man asked with a smile on his face. "So what do you think?"

"The suit and plane operated as you said they would." Lelouch said to his sponsor as he removed his mask before using a free hand to pull down on the black material that covered the lower half of his head. He shook his head to help his black hair flow more freely as his amethyst eyes met with those of the man before him. "My only complaint is the Sticky Gun Grenade which I am concerned could become a problem later so I'll use the spike and magnetic grenades you offered instead."

"Well there was a reason the Sticky Gun Grenade was shelved, but that armor you are wearing is one of a kind made for you alone."

"Maybe, but you did use some technologies that had been shelved for this suit." Lelouch said using his right hand to lift up his cape as if to prove a point.

Lelouch was referring to the black memory cloth cape he wore which was developed by DOATEC. For unknown reasons it had been shelved and never utilized. At first glance, it looked like a simple, flexible fabric like nylon on the outer layer, similar to a parachute, but when an electric current was applied through the black gloves of Lelouch's suit, the loose molecules realigned and become rigid, which allowed him to glide over long distances, additionally the material was water and fireproof.

The belt Lelouch wore was based off of a modified climbing harness for military commandos with the shoulder straps removed, but its metallic magnetized impact-resistant pouches, and canisters attached to the belt at ergonomic points for ease of reach was useful allowing Lelouch to carry a wide range of different weapons and tools.

Everything else was original having been produced by new technologies and preexisting ones, which was possible thanks to Fame Douglas using his considerable resources to make it possible.

"Well its all the more reason you have been going out there and using those criminals for punching bags right?" Fame replied with a cheerful demeanor as he was overall pleased with the success of the plane and the effectiveness of the suit Lelouch was using. "Hell even those men could get a shot off on you it would have bounced off since that can withstand up to a fifty caliber shot."

"I won't have to worry about conventional weapons that much is certain, but the people I'll be facing are anything but conventional."

"True, but the Dead or Alive Tournament will be unlike anything seen before." Fame expressed proudly as the pride in his voice was evident.

"But if what you fear happens?" Lelouch asked causing Fame's expression to turn serious.

"Then you'll have what I promised you as a fail-safe. I hope it won't be necessary, but with everything I have been hearing about, I am concerned my days are counting down."

"I understand," The former prince said although his thoughts were active taking everything he had learned about into account.

Its chief scientist and leader of DOATEC's private army and weapon development projects had been gaining favor with the Britannian Emperor, granting him a growing influence in the royal court, which could only be a prelude to trouble ahead.

Victor Donovan was the name of the man of whom despite being a highly capable and renowned scientist specializing in a wide range of fields with genetic engineering and cloning being a preferred favorite of science for the man. Publically Lelouch had heard little, but he had learned much about the man from Fame Douglas, about the man who had been proposing human experiments to create potent biological weapons out of formidable humans.

Fame Douglas had shot down the idea of course, but over the years his power and influence has begun to slowly wane, specifically within the Britannian Royal Courts as Donovan has been growing more popular with the Emperor and members of the royal family.

Just what kind of projects was he proposing? Lelouch wondered.

If Lelouch wanted to bring about Britannia's destruction then these weapon projects could not be allowed to come to pass. Even though Fame would not elaborate on certain details, but if one considered the fact he was willing to provide advance weapons and gear to a young man clearly dedicated to the destruction of the Britannian Empire, then the situation must be even worse than what Lelouch could even imagine. The situation must be dire indeed for Fame Douglas to turn his attention to said young man, but he lacks the manpower to launch a rebellion to topple an Empire.

Not yet at least…

"I'll leave for the Freedom Survivor tomorrow morning via the private helicopter you arranged for me at the airport?" Lelouch clarified, as part of their arrangement was that he would take part in the tournament under the code name: Zero.

Winning the tournament wasn't his objective even though the prize money would help him greatly, but he was to ensure one person in particular died by the end of the tournament regardless of the victor. The man in question was named Raidou, a degenerate ninja who hailed from the same hidden shinobi village Lelouch and Nunnally spent five years at.

I am not exactly thrilled about becoming a contract killer, but Raidou…he deserves death.

During his time at the hidden Mugen Tenshin Village the former prince had heard about Raidou and the reputation he had created within his own village before he was exiled. He had heard his fair share of unsettling stories, but one of them resulted in a friend he made in the village to endure a harsh life as an outcast.

I'll ensure he dies screaming for his crimes, but if his death will help further my goals then I'll gladly ensure his demise.

"I've prepared a special room for you on the ship so you can take off that mask safely, but use the special tools I have left you to ensure no one planted any bugs or cameras to get a look at you." Fame replied as Lelouch was familiar with the briefcase he had been given a few days ago. "The Shadow Hawk will be remotely piloted to a safe location off the shore of the island where the final rounds of the tournament will take place to give you a means for a quick escape."

"Right and the remote I am carrying will allow me to summon it to my location."

"That's correct, but if I end up assassinated then the navigation computer on your craft will direct you to the cache I prepared for you."

"If I can prevent it then I'll do it, so I wouldn't assume the worse yet. Still from what you have told me I don't blame you for preparing for the worst." Lelouch said as he thought Fame's preparations in the event if he was assassinated might seem like he is giving up on the thought of surviving, but without knowing who will attempt to kill him it was best to prepare for the worse as a precaution.

Not to mention it set the stage for Fame Douglas to get revenge on his enemies from beyond the grave through Lelouch.

"Thank you…I only wish I could have done more for you since your mother did save my life. She was one hell of a woman." Fame Douglas complimented as he fondly recalled a memory of meeting Lelouch's mother some years ago when she was known famously as Marianne the Flash one of Britannia's most legendary Knights of the Round members before she became consort to the Emperor Charles zi Britannia.

"I appreciate everything you have done for me so far, and I am sure my mother would be satisfied as well all things considered."

The former prince had found out when Fame Douglas approached him that it had been he who had arranged for his protection within the Mugen Tenshin Village through the Kyoto Group and the Ashford Foundation as he made some deals with the two groups in exchange for ensuring Lelouch and Nunnally survived with their deaths faked preventing them from becoming victims of royal ambition.

They had been sent to Japan to die after all since the demise of a prince and princess of Britannia would have served the Empire best, but Fame had intervened secretly on their behalf.

"If what you fear happens and they assassinate you. Then know I will hunt down and eliminate everyone involved and then I'll remake this world into a better one." Lelouch said with determination in his voice as he looked down at the polished black surface of his mask.

The world will soon know of Zero.

A/N: Ok first off Lelouch did receive training from Genra in the arts of ninjutsu of the Mugen Tenshin (Hajinmon) style ninjutsu, but he was taught elements of the Tenjinmon style of Mugen Tenshin to make it difficult for anyone from the village to easily determine who trained him.

This was done so he could survive the coming conflict and take a much more active role in the story.

I had originally set it up to where Lelouch would have sponsored Kasumi's entrance into the tournament to kill Raidou for his suspicious involvement in his mother's murder. But I wasn't able to develop a proper story from it and after some talk with some friends it became this version. His armor his high tech due to taking some serious measures to protect his identity but given the opposition Lelouch will facing (more than just mere humans and some fighters possessing superhuman abilities) and the fact due to the fact most of his shinobi training had to be done in secret hindered the development of his skills somewhat.

The suit is also designed to compensate for any shortcomings including adding some more power behind his blows since he isn't as physically powerful as some of the Dead or Alive's heavy hitters and is more of a fast and evasive fighter relying more on speed than strength and using tools, weapons and deceptions to win.

That and in order to protect his identity he'll need to be careful about who he fights because if anyone can recognize the style of combat he uses it could be used to figure out his identity.

Now for pairings I was planning to pair Lelouch with Ayane, but after talking to AnubisGundam0 about it I decided to let events of the story play out and cement the pairing choice later to ensure the best choice is chosen. Kasumi was intended originally to be paired with Lelouch, but I was concerned their personalities might not mesh well together compared to Ayane. So it will be between Ayane or Kasumi with only one of them who will win Lelouch, which could end up fueling the animosity between them as well.

On my profile page I am doing a poll where I am going to let you guys pick who Lelouch will face first.

I hope you guys enjoyed this chapter and the next one will elaborate more on Lelouch's time at the Mugen Tenshin Village. He spent five years there after Japan fell before the tournament begins to offer some insight on his relations on characters like Hayate, Ayane and Kasumi.
