The Fourth Faction

He had slain the beast, he had slain the black dragon. Cao Cao, covered in blood, sat against the stone wall behind him, the true longinus stuck out of the great dragon. Cao Cao could barely believe that he had actually destroyed a being that could rival the seraphs of heaven and the maou combined. He sat back against the stone wall in the cave on some forgotten island in the Pacific Ocean. The hero faction had made this their base of operations, but that night had been attacked by the black dragon and its forces.

"You think you've stopped me boy?" the voice of the dragon spoke. Its body began to glow a purple and crimson aura that radiated pure hate and malice.

The human hero's eyes widened, "impossible, the spear can kill gods with a mere scratch how can still live."

"True, but there are some things even your spear can't kill," said the dragon. "You have indeed sapped much of my power but you have not stopped me."

Cao Cao could only stare and mutter until he was broken from his stupor by a loud crack. Cao Cao's face paled at the site before him, the True Longinus was cracking holy energy leaking from the cracks and being swallowed by the flame like aura of the dragon. He pulled himself to his feet and tried to lunge for his weapon, but found himself unable to move as tendrils of purple energy had wrapped him in their coils.

"Your misguided actions have wrought only death child of man," said the dragon. "You have destroyed my physical form that much is your victory. But my soul will linger and I will reclaim my family that you stole from me, even if it takes years to do it."

"My people will stop you," said Cao Cao breathlessly.

"No they won't," replied the dragon. "Even now my Black Knights are destroying your faction, after tonight nothing will remain to rebuild it." The ground began to shake violently and the air became heavier as the intensity of the dragon's energy became more powerful.

"Know behold as humanities greatest weapon is destroyed by your incompetence!" exclaimed the dragon. The True Longinus shattered and the dragon's body disintegrated with it leaving the flaming aura behind. Cao Cao still trapped felt pain in his heart from the destruction of his sacred gear and screamed in agony as he began to die.

"Don't think you have escaped my punishment boy," growled the phantom dragon. "You stole my loved ones from me and you will pay the price. For I am the dragon of justice and vengeance, I send terror into all beings, my power can rival the twin heavenly dragons, I am Zero! Justificatum Vindicta!" The dragon's aura flared and wrapped around Cao Cao covering his whole body in purple flames. He screamed in pain as not only was his body being burned to dust but his sole was as well. When the dragon dropped the body all there was left a skeleton which disintegrated on contact with the ground.

The phantom dragon let loose a roar and flared his aura again this time a massive purple explosion ripped the cave apart. Outside heroes and knights did battle energy from the enchanted knights halberds killing the heroes were they stood. The explosion signaled their retreat the flames of Zero spreading across the island consuming anything in its path.

"Mr. Lamperouge."

His eyes snapped open, the images of purple flames dying away, looking up he saw the stern faced teacher in front of him.

"It would be greatly beneficial to you if you did not sleep in my class Mr. Lamperouge."

"Yes sir," replied Lelouch in a sleepy tone earning a glare from Shirley who had turned to face him. After class dismissed he was approached by said female who looked like she was about to blow a gasket.

"You were out gambling again last night weren't you Lelouch, that's why you fell asleep in class again."

"Hey guess you caught me Shirley," replied the raven haired boy then thinking 'if only you knew little girl.'

"You've got to stop that Lulu you'll get hurt," begged Shirley.

"I'll be careful Shirley," said Lelouch. "Now I have to go have lunch with Nunnally."

As he left he could hear the red head behind him yelling about someone always doing stuff like that. Shrugging it off he made his way across the campus toward the large eight story mansion at the other end. It was separate from the rest of the school and was surrounded by a wall that kept other students and people out.

Once he entered the gate his body was surrounded by purple flames and his appearance morphed. His hair became waist length, his fingernails turned black and pointed like claws, and his canines elongated slightly. Slits took the place of his pupils and his irises seemed to glow with power. His clothes changed as well his Ashford uniform changed into a dark purple suit with a red cravat with a gold jewel in the center. Finally a large high colored coat with crimson and gold highlights and twin tails at the end completed the outfit.

Upon entering the house he was greated by a familiar face, "welcome back Lelouch-sama."

"Thank-you Sayoko, I take lunch is almost ready and Nunnally is coming?" Lelouch asked the maid in front of him folded her hands on her apron and replied with a smile, "Yes master."

"Big brother," cried said girl running down the stairs, her purple eyes filled with joy. Lelouch could only laugh as he scooped up his sister in his arms. The day he had healed her blindness and paralysis had been a day of complete joy for him and he could not help but smile when he saw those bright purple orbs vowing never to take them for granted again.

"Welcome back," she said.

"Good to be back," he replied. "Shall we have lunch then?"

"Yes lets," cheered the girl in front of him the light bouncing off the twin silver rings on her hands.

While eating their lunch in the quite spacious dining hall, the table being able to hold a large banquet, an orange magic circle appeared next to Lelouch's ear.

"My lord everything is set up and we'll be ready for tonight," said the voice of Lelouch's top commander Jeremiah Gottwald.

Resting his silverware on the table Lelouch spoke back into the circle, "excellent Jerry I will be there at seven the operation starts tonight at midnight." Closing the magic circle he turned to see his sister's mood had changed.

"I take it that this is about the lead on what father is plotting?" said Nunnally venom coursed through her words when she said father.

"Yes it is," replied Lelouch. "Whatever Clovis has been doing it is related to that man's plan."

A smile crept onto the little girls face, "and you're going to disrupt that plan tonight."

"That's right," smiled Lelouch coyly.

"Meow"

"Ah you've finally come," said Lelouch as a black cat jumped onto the table.

"Meow" replied the cat.

"I know surveillance isn't what you would call fun but I them watched at all times," said Lelouch in a tone that said he had had this conversation before.

"Meow"

"Whatever, I do have a job for you tonight that might be more to your liking." This seemed to cause the cat to perk up. "Meow?"

"Yes I need the survalence and security room taken care of, it will require stealth and no little amount of courage, can you do it?"

"Meow!" said the cat jumping to the ground and bolting out of the room Lelouch laughing as it did.

Britannian Research Facility

The pilot shivered in fear in the cockpit of his Sutherland his compatriots had been cut down and laid in burning heaps on the ground in front of him. A figure in a black coat stood atop the wreck of one the frames staring at him.

"You bastard!" screamed the pilot unleashing a hail of bullets. In a blur of motion the figure disappeared the bullets impacting the wrecked Sutherland causing it to explode. The pilot swiveled his frame in a circle looking for his target, unleashing lead whenever he thought he saw movement.

"Where are you?" he screamed. A heavy thud signaled that something landed on top of the cockpit, following this was the sound of tearing metal. The pilot looked up to see the roof of the cockpit being sheared off by a black clawed hand, the man's eyes widened when he saw the black clad figure with to black and purple scaly wings standing above him.

"Here," said Lelouch as his hand shot towards the pilot who was trying to pull his side arm. Lelouch's hand wrapped around the pilot's neck and he wrenched him out of the pilot seat, the frame falling to the ground with the loss of the pilot. The two men however floated in midair Lelouch's wings spread wide, two gun shots rang out, the pilot looked down to see the two holes his gun had made. But instead of the creature dropping to the ground in pain the wounds began covered in glowing purple scales which faded away a second later to reveal untouched clothing. It was as if the gun had never been fired, the grip on his neck grew tighter forcing him to drop his gun and reach for the offending hand.

Lelouch snickered at the man's attempts to pry his hands from his neck, "it useless die."

With that Lelouch twisted his wrist and broke the man's neck, he then dropped the dead body to the ground a resounding thud followed. Lelouch then formed a purple magic circle near his ear and spoke, "area clear move in and secure the target."

Closing the circle Lelouch looked up to see two more Sutherlands charging him, a smile then grew on his face, "oops missed two."

Raising his hand towards the oncoming frames he grinned as he said, "twin dragon shot."

Two beams of purple energy shot from his hand and it the frames faster than they could dodge. The Sutherlands then became a fireworks show of explosions turning them into chard scrap metal. Afterward making his way into the main research building he came across corpses of slain security guards and other workers of the base. Finally he came to a large laboratory his Black Knights in their armor pointed their enchanted halberds at a group of bound and gaged prisoners on the ground.

"Is the target secured?" asked Lelouch.

"It is my lord," said the familiar voice of Jeremiah. Turning Lelouch saw the man dressed black armor with orange and green highlights he carried sword at his hip and an open faced helmet under his arm. "It's right over there."

Lelouch then spotted a large spherical container with hoses attached to it. He walked over to the computer terminal next to the sphere he typed furiously and brought up several files, before finding what he was after. His eyes widened when he saw the file before him he then began to grin like a mad man saying, "it's you hehehaha!"

Taking out of his pocket a small portable drive he inserted it into the terminal and then continued typing. A warning appeared on the screen followed by a window opening saying 'access denied, password required' sighing Lelouch said, "I don't have time for this."

He turned back to the prisoners and walked over to a man dressed in a white lab coat.

"What is the password?" Lelouch asked.

"I won't tell you," replied the scientist. Lelouch sighed in frustration and raised his hand towards the man a mist like purple aura came from his hand and wrapped around the scientist who fell to the ground screaming. He writhed on the floor in utter agony, Lelouch then stopped and said, "if I was not short on time I would search through your memories for the password myself. But I don't have time so you will tell me or more pain will befall you."

The scientist lifted himself up and opened his eyes and looked at Lelouch. The first thing his dilated pupils saw was Lelouch anger filled glowing purple eyes mustering his courage the scientist shook his head no.

"Oh so unwise," said Lelouch unleashing the purple aura again. The scientist fell down again screaming not being able to muster any other sound except screams. He began to cry tears of blood and his hair started to turn gray before Lelouch stopped, and when he did the man coughed up blood staining his white coat.

"This is the last time what is the password," said Lelouch in a dark tone

"5-4-3-1-5-9," mumbled the scientist as he began to shake.

"Thank you," said Lelouch as he went back to the terminal and began downloading the files.

"Jeremiah," said Lelouch as he turned to leave. "Have the container moved back to my mansion, I'll open it there."

"Yes my lord," replied the knight. "What about the prisoners sire?"

Turning back Lelouch looked at Jeremiah and said, "the files have given the answer Jeremiah. There are no prisoners to take only rabid animals to put down. Justificatum Ultionem!"

"Justificatum Vindicta! Hail Zero!" said Jeremiah. The prisoners began struggling and crying out through their gags.

"Justificatum Vindicta! Hail Zero!" said the Black Knights who then released the energy from their weapons.

A.N. Before any one says anything the story of what happened before the invasion of Japan and the healing of Nunnally will be explained in later and coming chapters. The coat Lelouch wears here is a trench coat version of the Zero cape. Justificatum Vindicta is Latin for justified vengeance. Reviews are welcome. Until next time PhoinexFire out.
