It's body was made of blades.

This was an undeniable truth of the world, one that even "normal" people would hesitate to call fully human if they saw it in some of it's more vulnerable states. It gave itself to it's purpose, never wavering, and never regretting. All for the sake of seeing a dream again, one person who was like an illusion, always far away. Only if the sword chased endlessly, and one waited eternally, would they meet again.

But for the sword, no price it had to pay was too small.

For the Sword, all the evil in the world was nothing compared to her smiling face.

For the Sword, it's dreams would be realized.

The Sword could not give up.

For his will was Unlimited

His body was steadfast as a Blade

He would continue to spread his Works

The Blades name was Shirou Emiya.

How long had it been since he had seen her face, his Saber? There were nights where he could do nothing but think back on his time with her, remembering the moment that he realized he loved her, the moment she admitted the same, before disappearing into the mist of early morning. "So, It's been 12 years, huh, Saber." said Shirou as he sat up, gently stretching his stiff muscles.

He was currently in his shed, the place where he first met that ephemeral dream. He muttered Trace, On as he got to his feet, calmly producing a familiar black blade, the weight comforting in his rough hands. He admired the sword, reflecting on its craftsmanship,but more importantly, where he got it."Archer…"

Archer was the man's alternative future self, a possibility that he had met in the event known as the Fifth Holy Grail War, a bloody conflict between seven mages and seven servants, powerful heroic spirits from legend, to claim the Holy Grail and the wish that the owner was permitted to make upon the omnipotent chalice. Shirou himself had participated in the battle unwittingly as a master, his summoned servant being the great hero Arturia Pendragon, King Arthur, The legendary King of Knights.

This was also the woman who he would fall in love with for the rest of his days, striving to accomplish his ideals in hopes that he would meet her again one day.

Which brings us back to the matter of Archer. Shirou had spent countless days pondering the meaning of the strange red knight, Wondering why the mere thought of him was enough to make his blood boil. That was until he had looked in the mirror 10 years later. He was now the spitting image of that man, and with the revelation of Archer's identity came something else, The Unlimited Blade Works.

As Shirou shook himself from his reverie, he dispelled Kansho and focused himself.

"I've been too preoccupied with the past lately" he muttered quietly to himself, already on the way out the door.

It was a quiet, moonlit evening with a peaceful wind blowing from the west. It would be quite some time before Shirou Emiya felt that breeze again.

The shadow breathed, it knew what was coming. What it could have been was no longer enough. The chaos seethed, seemingly with new vigor. The shadow knew that it had not the time. It needed to awaken, but it first needed a vessel, someone who could fill the assigned role regardless of the circumstances.

A Demon King would soon be born, whether they wanted to be or not.

Shirou walked into the cold night air, appearing reminiscent of a certain red knight. Even as he thought of the irony of his attire, he continued to walk towards the objective of tonight's outing, the holy grail system. The system itself was contained in a cave far under Ryuudou Temple on Mount Enzo, so he had to travel on foot to reach there at all. The mission objective was to observe the strange fluctuations detected in the city's ley lines originating from this point.

As Shirou exited the trees, he saw the cave mouth, dark and ominous. Standing nearby was a familiar face."It's been a while, Rin" Rin Tohsaka, someone who Shirou had a history with, even having started a relationship that had gone on for the last decade. "It took you long enough, idiot" said Rin, sighing exasperatedly. Thier relationship was somewhat strained, as he had someone else in his heart, but that had certainly not stopped Rin from blatantly declaring that they were going to date,regardless of what he said, after she had lost her temper while observing his "suicidal" tendencies of course. But she was clearly exaggerating, he wasn't that bad.

"Everyone else is already inside, surveying the site" she said,narrowing her eyes at him accusingly."What could have possibly have taken so long for you to be this late?" At her accusation, Shirou rubbed the back of his head and smiled awkwardly at her "Well I kind of dozed off there for a while…" he stated weakly, having no other real excuse but the truth.

Rin looked at him, and then looked to the side and sighed. "You always pick the worst possible times to overwork yourself." she said, appearing somewhat dejected. She then whipped around, facing the cave mouth "Well then, let's go, no more time to waste." she said, already having set off into the cavern."Haaah….what I do for that girl…" sighed Shirou as he hurried after her.

The shadow felt something shift, as if the world itself had a violent convulsion, it felt the very fabric of the world break apart as portions of it were rewritten, reinterpreted, somehow...remade.

The shadow reached out with it's mind, sifting through the information available to it…..

"I desire the death of the Elemental Lords"

A desire that should not have come to pass, for the entity that held that wish had not yet come to exist. The shadow considered this, for the briefest of moments, and had no answer to give involving the reason for the occurrence. As the shadow was HERE there was no way that it could be THERE.

Yet, fate is ever fickle,it twists and turns according to it's own will, ensuring that some events will come to pass, regardless of the measures other things may take to divert the course of destiny. This was not one of the works of FATE. For surely, thought the shadow, this feeling of familiarity could only be called NIGHT.

The girl breathed hard,having broken into a cold sweat, feelings not her own flowing through her body like electricity. She had felt something inherently wrong about the world while she slept, as if nature and the world itself had been rebelling against something for a split second, trying to prevent something from coming. Then suddenly everything had quieted down, as if nothing of notice had taken place whatsoever.

She knew something was wrong, terribly so, so Restia faded from view in a rain of black feathers.

Shirou and Rin entered the large central cavern after several minutes of walking while exchanging mild banter. The path opened up into a large cavern that could be said to be about 50 meters in diameter,all of which was covered in the ridiculous amount of magic circles that made up the holy grail system.

The cavern was dimly lit, light provided only by magical lights carried by some of the approximate 20 individuals already in the room.

These were the Enforcers, the Mages Association's strike force and private field team. Composed of mainly combat oriented mages, the enforcers were the worst nightmare of sealing designates and were charged with hunting dead apostles and enforcing the laws of magic. Like the first law "Maintain the secrecy of magic at any cost." In this case, the "at any cost" bit was the complete and utter destruction of everything related to the infraction, friends, family, your home, even your pets. The rule was that if you reveal anything, everyone you knew would perish.

Of course, that was not the objective for this particular venture.A single squad of enforcers had been assigned to survey the remnants of the "highly dangerous" holy grail. 'The Mage Association seems to at least be taking this particular mission seriously', Shirou thought. In the past the Association had been all but deaf to attempts to investigate the grail. The reason for this was because at the Clocktower, the MA headquarters, it was thought of as just "a small ritual carried out by the novices in the far east."

This all changed however, when they started detecting an extremely powerful wave of prana running throughout the land lines of the entire world, all originating from this point.

As they approached, they were hailed by a man standing near the center of the cavern.

"Glad that the both of you could finally make it" said the man, speaking with an air of impatience. "Sorry to have kept you waiting, Lord El-Melloi II" uttered Rin , tone neutral, face impassive. Lord El-Melloi II was a tall man of European descent that wore dark clothing coupled with a red cloth hanging around his neck and was quite imposing with his long dark hair and constant scowl.

"Well now that you are here, what do you make of this?" said El-Melloi, gesturing to the circle. It was a massive, incredibly complex circle that pulsed with an ethereal purple light that,somehow, seemed almost alive in the way it softly pulsed.

"I say that it should be impossible." said Rin, still expressing detachment in her tone. "The Grail should have long ago lost all traces of mana within, much less still be processing and cycling it after we dismantled the majority of the system two years ago."

"I would agree, were the evidence not under my feet at this very moment" said El-Melloi "It just shows how much trouble you Japanese can be."

"Why you…" started Rin, her mask finally cracking at her annoyance with the man in front of her. You wouldn't think it from the way the woman looked, dressed in a red coat, blouse, and skirt combo, being of medium height with bright blue eyes and shoulder length black hair; But after all this time, Rin was still just as much of a tsundere as ever.

"Now Rin, don't incapacitate the nice lord who sponsored you." chided Shirou as he stood to the side, watching the conversation unfold. Rin shot him a dirty look,before huffing and looking at El-Melloi "Well,have you found anything useful yet?" she asked, suppressing her inner anguish.

"Why yes, actually" said El-Melloi, looking as sour as ever."We have discovered that there is a consistent flow of mana coming from within the grail itself and leaking into the surrounding ley lines." He stated; tone serious. This revelation brought scowls to the faces of both Rin and Shirou, both quietly considering the possibilities. "If the grail is reactivating…." said Shirou in a grave manner, stepping forward to get a closer look and examine the circle.

I desire the death of the Elemental Lords….

Suddenly the circle flashed violently, light pouring from the ground in droves.

"What?!" exclaimed Shirou as the ground around him fractured, a familiar black, mud like substance frothing forth from the fissures. "SHIROU!" yelled Rin who had somehow gotten far away, or was it far above? He felt himself loose all sense of weight, as if the world had bent, twisted, split apart at the seams.

He felt himself fall and felt an entirely new sort of scent, a stinging, foul odor that reminded him of madness. As he fell he thought he heard a voice call to him once more.

But all had faded to black.

The shadow sensed a distortion between the planes. Some sort of interference between the domain of humans and Astral Zero. As the shadow searched, it felt the build up of energy, the enemy was hunting, most likely having sensed the same distortion.

As it came near, Light pierced the eternal darkness.

In this place where the impossible had occurred, in this realm of nothing, light and dark connected. How long had it been? Moments?,Days?, Years?, or some incomprehensible fraction of eternity? Neither comprehended what the other was. One was lost and confused, what was in front of it was new and alien.

The other,however,saw the opportunity present. For when the enemy had drawn near, a radiance had permeated the nothing, briefly inviting the warmth the shadow had desired for so long. It knew that, somehow, this was the ideal form that it would use. It WOULD have this soul!

It was to be an absolute truth, divine providence that could not be rebuked. But changes would be needed, yes, as powerful as the shadow sensed this vessel already was, it was not quite suitable for the shadows needs. The shadows presence alone would already have changed the body much, but something new was needed, something extra. 'Ah' the shadow though, that would do nicely. As the shadow was in direct contact with the vessel, it had options that it had not had for millennia. So as the shadow entered his body, changing it in ways that it otherwise would not have, and impressing upon it the shadows will and very essence, Shirou Emiya dreamt of a black haired dark angel, deep blue eyes, and his other half, a women who still, even now, waited for him beyond time,endlessly.

With this, the wheel has begun to turn, the story unfolds, the world quivers.

For that day, the Demon King was born again.
