Hey, all!

I have a little treat for you, something I don't do very often and as many of you are aware most of my stories come from dreams.

This will NOT be a series, only a one shot.

I tried not to make it too long but we all know that doesn't always happen. J

Without further ado, I do not own rights to either Yu-Gi-Oh! or Fate!

Enjoy!

Yu-Gi-Oh! X Fate: Stay Night Crossover

From the top of a skyscraper, a lone figure stared down at the slumbering city with eyes so cold that they may as well have been made of ice. The long jacket they wore would be brushing against the ground if it weren't for the growing strength of the early spring breeze. A passing helicopter briefly illumines masculine features, revealing dark chestnut hair trimmed and styled in the twenty-first century's highest fashion and a concentrated line upon their lips. Their near crystal hard eyes softened ever so slightly as a smaller figure stepped up to stand next to them. Though it pained him, he kept his gaze forward as the phantom he could clearly see standing beside him smiled. "So it's starting again?" a feminine voice softly asked, head tilting to the side. He nodded. Platinum hair was swept from her face, revealing stunning blue eyes that made even the precious Heart of the Ocean on display in some far off museum seem lackluster. "Then perhaps you should be going now." He huffed, hands clenching into fists at his side as her image dissipated like smoke.

No matter what he would not fail this time. The one light atop of the roof illuminated the magic circle he had formed earlier, his gaze unwavering as he moved to stand within its center as the watch upon his wrist began a countdown. He knew the spell, had all of the necessary components, and had spared no expense in securing the catalyst that would ensure his victory this time: an ancient fossil that was supposedly a mighty dragon. "Silver and iron to the origin. Gem and the archduke of contracts be the foundation. Let sapphire the colour I pay tribute. Let rise a wall against the wind that shall fall. Let the four cardinal gates close…"

. . . .

"Marik, you can't be serious!" Ishizu and Odion banged against the wooden door that separated them from their younger sibling. They had woken to find his bed empty and several supplies missing from their father's workshop. It had been sealed off for the last few years since he had passed, his will explicitly forbidding any from entering, but the seal upon the room was broken. A spell was preventing the door from opening now, causing alarm to fill the two older Ishtars. "Open this door! The Mage's Association will surely have you severely punished for this!" Her cornflower eyes grew wide when the telltale chime from the clock tower several blocks away began to chime and a low spoken chant reached them.

"Let the three-forked road from the crown reaching until the Kingdom rotate." Marik's hair practically stood up as the magical energy gathered around him, which was saying something since his hair was the wildest of their family, but he remained within the circle's center even when crimson sparks began to rise. The room had grown cold enough that his breath was visible and the fine hairs across his skin were standing upright as the ground rumbled beneath him. There was no turning back now. Straightening his spine, he continued the chant, determined to fulfill the task that even his coward of a father could never complete and would finally be free from the looming shadow that lingered over their family. His hold tightened around the broken horn that he had found within a locked chest. It had taken him several hours to get through the door and it had taken almost just as long to retrieve the catalyst. He glanced towards the door as his older siblings begged him to cease but he ignored them and faced the glowing circle. "I herby declare, your body shall serve under me. My fate shall be your sword…"

. . . .

A young man's head snapped upward as a chill passed down his spine, closing the textbook in his hands with a soft snap as the sound of footsteps came from above. He even held his breath as he heard a cupboard and familiar refrigerator door open then close and exhaled slowly when the footsteps faded towards the staircase towards the upper floor. Grandfather had a habit of getting up in the middle of the night but he had thought the added sleeping aid that was slipped within the elderly man's nighttime tea would have been enough to ensure absolute privacy. Apparently it wasn't enough. Lilac eyes closed as he regained his breath and then turned his attention back to the book in his hands. The once upon a time mage who was his grandfather had told several stories of the wars secretly waged for the fabled Holy Grail, he practically preached about the time he had partaken when he was younger than the teen himself, and it was time to see if the old man's tales were true. "Submit to the beckoning of the Holy Grail. If you will submit to this will and this reason…" He paused as he recalled the warnings of his grandfather. This secret ceremony was not meant for the faint of heart nor was it for those who were unfamiliar with war. If he stopped now then he could return to bed, go to school in a few hours after a brief snooze, maybe even meet up with his friends later. Finishing the incantation would surely turn his life upside down. His jaw set as he swallowed the lump in his throat, a hand rising to briefly brush away the blonde bangs that stuck to his forehead. The mana within his body was nearing its limit so it was now or never. His catalyst, an ancient toy that had surprisingly held firm against the sands of time, was gently placed at his feet as he closed his eyes. "…then answer!"

. . . .

"From the Seventh Heaven, attended to by the three great words of power, come forth from the ring of restraints, Protector of the Holy Balance." The book within her hands flared with heat, causing her to suddenly drop it as the lights flickered than died as a piece of the ceiling above her collapsed as the ground beneath her quaked violently. She sputtered, blinking rapidly to clear out the tears that caused her vision to blur as billows of smoke and debris that rained down from the ceiling above. What was supposed to be a short study session had turned into an all night intense escapade through the old weathered book she had borrowed from the library. It was unlike her textbooks, almost every page contained strange circles that oddly looked like the hand-me-down rug that she had inherited from her great-grandmother that was currently buried under several inches of rubble thanks to the earthquake that had hit. There hadn't been any reports of any occurring nearby for at least a year, weather reporters and scientists were fairly accurate but even they could be wrong sometimes she guessed, but she couldn't help but groan as she surveyed the now gaping hole in her roof. "That's just great," she huffed, one of her hands rising to comb through the chocolate locks that had fallen into her face. Living alone had its perks but also its downfalls. No one else was there at the time of the incident, meaning that there wasn't a worry that someone had been injured but that also meant that there was no one to offer testimony of the strange event to the insurance agency or to lend her a hand in currently cleaning up the atomic mess that now littered across her living room. Her hand rose, fingertips brushing the cartouche that hung around her neck that her father had given her from his latest business trip. It's rugged metal surface was meant to bear the wearer's name but it had been worn away over time until only a few traces of gold remained. Her father wasn't one who paid much attention to superstitions or tradition so he had simply shrugged when she asked bout it. He would send her money every month, like an allowance, that would cover rent and anything she could possibly need minus the joy of knowing that someone was home waiting for her. This particular cartouche hadn't been bought in a shop though, he had been gifted it by a business partner when even they couldn't distinguish the name upon it, and it had found its way into her own hands. It wasn't girly or pretty by any means but it suited her just fine and would rarely take it off except to bathe. An exasperated groan slipped between her lips as she surveyed the living room, hands resting upon her lips. "I don't even know where to start."

"Introductions would be wise," a deep baritone voice called. "but that in itself must be carefully considered." It was velvety, caressing her very soul as if it were wrapping her in the finest silk, and carried heavy authority yet the hints of sincerity and curiosity. The clouds outside parted as she searched for the source and felt her breath catch as she found it sitting atop of the rubble as if it were a throne and was bathed in the full moon's light coming in through the hole in her roof. The wild hair atop of his head was familiar, ebony if it weren't for the crimson tips that stood up in every direction and the golden bangs that were upright in a crown-like matter, but what kept her star struck were his eyes. Sharp amethyst eyes with a mulberry ring around the pupils calmly watched her as she blinked up at him for several seconds, as if he was waiting for her to make some sort of move.

Move she did. Cerulean eyes wide, she fell backward with a shout and felt panic fill her as her heel caught against a fallen beam, bracing herself for the coming fall that never came. Instead she had found herself within a pair of tanned lean arms that were decorated with golden bands and was pressed against something firm yet still held a softness underneath a fabric that made her think of the linen drapes she favored that were hanging within her bedroom. Sandalwood with the faintest hints of cinnamon and sunshine tickled her nose as she was placed upon the couch. The stranger knelt on one knee, a fist resting above his heart as he asked if she was alright. "P-peachy," she mumbled, withdrawing from him as she spotted the large eye-like diadem that threatened to overshadow his features. "I don't mean to be rude when I say this but get out." His head tilted at her shaky voice. Understanding filled his eyes when he glanced about the room and then noted the hole in the ceiling. Perhaps she was a bit disoriented from the summoning ritual itself that it was difficult for her to understand what was occurring. He bowed his head, standing and detaching the dark violet cloak that was attached to his shoulders with a flourish of his arm that vanished into thin air before it could reach the floor. Right in front of her, tendrils of gold rose from the floor that carefully picked each piece of rubble and within the blink of an eye the roof above was repaired. She stood on wobbly legs as she moved to stand where the mountain of rubble once was. There weren't any cracks or any other sign that there had been a hole in the ceiling to begin with! Her gaze wandered back to the stranger as he took her vacated seat as the lights flipped on with a snap of his fingers. Swallowing the initial shock and still lingering suspicion that he was someone she should be calling the police on, she took a deep inhale through her nose and straightened her back. "I have no idea who you are, since you literally crash landed in my living room at the break of dawn, but you fixed it and for that I guess I should thank you."

"Think nothing of it," he bowed his head. "But your words are appreciated, Master." His brows rose when she questioned him about the honorific. Blinking, he stood and crossed the space until he was standing before her. "Surely you jest. Perhaps you sustained a concussion during the summoning."

She held up her hands, retreating a step to put some space between them. "I didn't hit my head, okay? I'm underage so this isn't some alcohol induced madness and I don't take kindly to medicine so that's out. Maybe I'm just tired. I have been staying up later than usual and haven't been eating as much since I've been so focused on my studies. Yeah, this has to be nothing more than some sort of dream or hallucination…"

Concern filled him as she paced about the room mumbling to herself, his eyes following her as she did. He had cleaned the eyesore of a mess as well as the hole that was caused by his summoning and yet she seemed lacking of what was occurring. The invisible mana connection linking them together flickered as she stumbled and he quickly moved forward in time to catch her before she collapsed. "Master, as a mage, you must be careful of how much mana you exert. Much more and you will render yourself unconscious" Astonishment filled him when her confused gaze met his. There was no hint of understanding within her oceanic eyes and there was a screaming need of answers that swirled amongst the tears that threatened to spill down her fair cheeks. This girl, his master, was not a mage. His hand carefully cupped her left, lifting it so that she could see the command spells that now rested upon her skin. "Master, you need not answer, but if you would, please tell me your name."

Her eyes instantly locked on the strange markings upon her hand when they came into view. They looked like the strange diadem he wore and she now recognized the strange symbol upon both: Eye of Horus, an ancient Egyptian symbol that she had seen in countless of her textbooks. "M-Mazaki…Anzu Mazaki…" she croaked, attempting to swallow the lump in her throat but failed and slipped into unconsciousness.

He adjusted his hold so that he could carry her easier, one arm holding her close while the other was within the crook of her knees, as he stood. His gaze combed the room, burning invisible runes and spells within the residence to prevent any other servant beside himself from entering. It was difficult but he could sense the presence of a few other servants close by; the highest one filled him mind with an animal, a Rider; the one farthest West felt the most dangerous, even with the vast distance between them, surely a Berserker or a worse; closer from the same direction was the obvious hints of a Castor. To have three so close to his master caused him concern but he was confident in his abilities and was not one who shied away from combat. "Master Anzu Mazaki, I swear that I shall do everything within my power to ensure you live through this Holy Grail War, but for now we both must rest."

. . . .

Kirei Kotomine folded his hands, eyes locked on the door that lead outside of the church. "So it has begun again," he whispered, his left hand rising to form the cross. "Another Holy Grail war is upon me." Cold emotionless eyes glanced to the right as his own servant appeared in the icy clouds lingering from the summoning, a chilling smile raising the corners of his mouth. The temperature of the church's sanctuary dropped several degrees as a man with platinum hair craned his neck this way and that, the air filling with the sounds of cracks as he flexed his newly manifested being. The scars covering him from head to toe that stood out like neon signs against his dark skin as his attention focused upon the Overseer. Kirei's eyes grew wide as the servant he summoned stalked forward, their slightly crazed eyes piercing his very soul as they growled softly under their breath. The power radiating off of him was nearly overwhelming, even for the veteran Holy Grail participator, which meant that this servant was much different that any he had summoned previously. He hadn't used the verse to summon a Berserker so who -or what- had he summoned?

A quick note on the summoning text: there were several different translations that I've found (from the different series types to the different class of servant incantations) and I found this one on dance_around_magic_._tumblr and it happened to go well with what I had originally planned. I originally saw this as a one-shot so I do not intend to continue on with a story but perhaps this can be a one-shot collection sometime in the future.
