Prelude 1- The Demon of Grimm

The Carter family was very well known. They were the biggest military hardware developer's and merchant's in Vale, maybe even the world, and it looked like it was going to continue for at least a generation longer. Their heir, Ryner Lee Griffin Walker Hunter Carter, was a 18 year old boy with a brilliant mind. When he was just 7 years old, he came up for the schematics' for a prosthetic arm which reacted to the users' aura. Baring in mind it did not work, but it did however create the basis of a whole new kind of science, and unknowingly to Ryner, warfare.

Unknowingly, Ryner had practically brought new weapons to the table. These prosthetics' could give people sword-arms, claws and anything else you can think of. And unknowingly, Ryner was also the heir to a monstrosity. Not just the metaphorical sense of the company, and the literal sense. Ryner was host to a powerful demon of Grimm. Not just any old powerful monster, if that was the case, there would be a lot more powerful host's that could match his demonic strength. No, he was host to the first, most powerful demon of Grimm in existence. It's name was, "Legion."

However, Legion did not awaken until the night of Ryner's 15th birthday.

Three years' ago, On Ryner's 15th birthday.

The sounds of gunshots' and screaming could be heard throughout the mansion. "Search for them!" a voice roared. It just so happens' that 'them' were Ryner, his mother, Rachel Carter, his father, Hunter Carter and his little sister, Sapphire Carter. Suddenly the door was forced open and a voice could be heard "I found them!" it yelled. And then, 10 gunshots', but they did not hit their intended targets. No, they had all hit Hunter, he had stood inbetween his attackers bullets and his family. But he could not pass on, not while his family's in danger, a bright orange glow in Ryner's dark crimson eyes. Ah, so IT had awakened. The being his ancestors had contracted with so many centuries ago. So HIS son was meant to be the next Demonblade. HIS son was strong enough to hold the power of Grimm. With a sense of pride and reassurance, Hunter Carter passed from this world. Over the sound of his mothers' screams of horror and his sisters' pleads for their father to come back, Ryner heard a demonic voice, it sounded like thousands of voices at once, men, women, children, and the pitch was strange, one minute it was so high it could break glass, the next it was a deep throaty growl.

"Do you need power?"

'Yes'

"Why?"

'Revenge'

"Revenge, oh how satisfying. I will certainly get a good meal tonight, very well, I shall grant you power. Now go forth, become my sword."

On those words' , Ryner walked forward and shoulder barged the man, sending him staggering to the ground. Ryner then quickly turned round and closed the door. "Big brother, what are you doing?" asked the curious 14 year old Sapphire. "Shh Saph, don't come out right now, I'll be back soon." replied Ryner. "You promise?" "I promise, take care of mother. She's in enough shock as it is." "Ok, come back soon big brother!" she replied innocently. Smiling at her innocence, Ryner turned around to face his family's attackers and his fathers murderers'. "So, which one of you scumbags are first?" Roaring in anger, the grunts open fired, generating a hailstorm of dust.

When the dust cleared, Ryner still stood there. This time wrapped in a shadowy aura with two thin, long black snakes with piranha shaped heads, without the creepy lights. The snakes eyes' glowed a bright orange, much like Ryners' when the demon granted him power. There were dozens of razor sharp teeth in their mouths, sharp, bony, silver colored spikes ran down the center of their head and down their spine.

In a flash, one of the snakes darted out and grabbed the one that had blocked the doorway by a foot. Then the other grabbed his other foot. The snakes then ripped the man clean in two. Spilling blood, guts and entrails onto the floor.

That was one down, a heck of a lot more to go.

The snakes darted out once again, this time wrapping around another grunt, then it burst out his chest, giving a shriek that was also a roar at the same time.

The next one open fired, only for the bullets to bounce off of Ryners' aura. One of the snakes grabbed the man by the throat, the other grabbed his rifle. "The Carter Mk 5 automatic rail rifle, capable of penetrating 3 meter walls', 30 round magazine, collapsible stock to switch between maneuverability and stability. Capable of being fitted with a bayonet, under-slung grenade launcher, under-slung flamethrower, under-slung shotgun and any sniper rifle scope up to x12. This is considered one of the most advanced guns of our time, it was only issued to special forces a few months ago." The man would have probably been impressed if he was pissing himself in fear. "How does feel, knowing you gunned do you gunned down the creator of this weapon in cold blood. Or was there a different motive? Wealth? Power? Come on, out with it!"

"M-M-Monster!" the man managed to yell out, his voice cracking. "I see, know that your comrades are dead and you weaponless, I see you for what you really are, A USELESS SNIVELLING LUMP OF MEAT!" "Shut up! Your just a dog to the Carter family! A brat not even fit to call himse-" "SILENCE!" the man began to whimper in fear. "I'm a dog?" Ryner asked, one of the snakes rearing backwards. "Then your dog food." the snake darted forward, ripping open the mans chest and devouring his insides. His screams of agony could be heard throughout the mansion. Drawing the other grunts' to Ryner.

One of the snakes handed Ryner the Mk 5. The gun would have looked like a normal musket. If it wasn't for the drum mag and x2 scope and the pitch black paint job.

The door was kicked in and a group of grunts charged in. "Open fire!"

They did just that. They also died doing that. Ryner took aim at one, his aura pouring into the gun. He fired and a black blast came from the gun, blowing it up in his hands, tearing his hand off, but at the same time hitting a grunt in the chest, the sheer force of the bullet combined with the aura tore the poor guy in half. Then something happened that not even Ryner was expecting. His arm regenerated. One of the snakes then darted forward to the next grunt. Grabbing his gun and ramming it through his stomach.

The next grunt got his gun ripped from his hands and clubbed against his face, tearing his head of his body. The next one met a much simpler end. He was grabbed and thrown out the fourth floor window. "Big brother, can we come out now?" "Not yet Saph, I still have business to take care of." "Business indeed." Ryner whirled round to see where the voice came from. It was his uncle Phoenix. Phoenix Carter was a tall man, standing at 6 ft 7 inches. He was extremely skinny and scraggly, and a very detestable man. He wore a purple suit with white pinstripes and his black hair was swept backwards, the back of his hair forming a ducktail. He wore his customary shit-eating grin. "Well, certainly this outcome was unexpected." What do you mea-" And then Ryner saw it. The grunts uniforms had span style Carter Private Security Providers written on their chest's and backs'. Of course, the Mk 5's, the uniforms. It all made sense. Phoenix Carter was responsible for the death of his brother and Ryner's father, the late Hunter Carter. Filled to the brim with rage, despair and sorrow. Ryner did the only thing he could think of. He was going to make his scum of an uncle pay. Unknowingly to both Phoenix and Ryner, a black vortex with the occasional spark of orange lightning grew in Ryner's hands. Then Ryner charged forward and punched Phoenix in the chest, the vortex turning him inside out. It was over, he had got his revenge. Come out in five minutes he yelled through the door. "Okay!" replied Sapphire nervously.

Then Ryner began to write a note.

"What are you doing?" Said the dark voice of Legion.

"Saying goodbye" Ryner replied aloud.

"Why exactly?"

"I can no longer stay here. I am no longer human, therefore I must cut all ties to my past life"

"What a foolish and naïve way of thinking brat. But if that is your choice."

"It is."

"Very well, make haste. The sun will rise soon and you are at your weakest in the light."

"I can't go by Ryner Carter anymore, what should I call myself?"

"Hmm, you may call yourself- Blade"

Three years' later

In the time Ryner had left his family and human life behind. The Carter family had became royalty. It would have made Ryner a prince if he had stayed behind. He always scoffed at the thought. He was NOT prince material. Best leave that stuff to Sapphire.

The train through Vale was a technological advancement to mankind. It allowed people to get from one location to another in relative safety. Once the train stopped at it's destination, 15 men in black suits got on board. All wearing masks over their face. "Alright people! Hand's in the air and no funny business!" Everyone put their hands up immediately, except for one boy. He looked about 18. He had medium length hair with red tips. The bangs currently covering his dull crimson eyes. The slanted forward spikes on the top of his head shifted slightly as the train started moving. The boy had a thin but muscular build. He wore a crimson sleeveless hoodie, which showed off his bare arms, his right arm covered with a tattoo of a Chinese dragon. He wore black baggy cargo pants with a silver chain hooked onto his left waist and going down to slightly above his right knee. He wore black combat boots that looked like they had seen their fair share of travel.

"Hey! You looking to get shot!?"

No response.

"Hey!"

The man walked over to the boy. He reached to grab the boys hoodie but didn't make it.

A blood geyser erupted as the man's arm was swiftly cut off. The man looked more shocked than anything else. Then before he could register the pain his head split diagonally in two.

Now you could get a good look at the boys' weapon. Or in this case weapons.

Weapon one was the black one-handed sword, Oblivion. The upper side of it's blade was crooked and jagged, (Like Omega Weapon from Finall Fantasy XIII). At the press of another button it could change into a revolver.

Then there was a white sword, named Forgiveness. The upper side of the blade was serrated, while the bottom was also serrated (Like Lion Heart, also from Final Fantasy XIII). It had the same ability's as Oblivion. Then there was when the two combined. It could turn into a two-handed sword. A double-sided battle-axe. A assault rifle and a spear.

He swung the black sword and impaled a man in the stomach. He then ripped out the sword, taking the mans' entrails with it. He then swung the white sword in a arc, decapitating two men. Four down, eleven to go.

Changing his swords' into their two-handed form, he charged and swung the blade, piercing one man through the chest. He then tore the blade through the right side of the mans' body, sending it into an arc and cutting the man next to him in two

Six down, nine to go.

Then, a shadowy aura surrounded the boy and two dark snake-like creatures floated over his shoulders'. Suddenly they darted forward, tearing out one mans throat, while the other speared a man through the chest. The snakes' grabbed one of the railings and ripped it from the ground, they then threw it and impaled three men.

Eleven down, four to go.

The boy darted forward, changing the swords to a spear, he then pushed the spear forward roughly into a mans' mouth, the tip of the spear came out the back of the mans' throat. He then switched into revolver form, firing one revolver, hitting a man in the right lung, while the other hit the man in the forehead.

{Battle music end}

That left one man. No, the boy would spare him. Leave him to tell of what he saw today, the day the black demon slaughtered his comrades. "Who, in the hell are you!?" "Me? I'm Blade Hunter."

With that note, the boy gave the man a lazy salute and then fell backwards off the train.
