A/N: well here I go again, oh and before I forget I own none of the rights to RWBY, nor do I won the character of Shirou Emiya, if I did well I wouldn't be writing this, anyway I hope you enjoy.

Chapter 1: a sword is summoned

Within an infinite number of realities, an equal number of possibilities exist. Shirou Emiya, in one reality he becomes a counter guardian, in another he lives a long and happy life, and yet another he was not saved form the fires that, in another reality forge him into a blade without equal. Weiss Schnee, in one reality she is a member of team RWBY, in another she died to the white fang. In this reality Weiss Schnee should have died to the Arma Gigas, but with an infinite number of realities come's an infinite number of possibilities.

Weiss Schnee blocked a strike form the metal behemoth's sword with her own, she skillfully jabbed at the armored legs, the fine point of Myrtenaster harmlessly bounces off, and with each blow Weiss gets more and more exhausted. The massive sword came from the side, at this point Weiss is too tired to lift her sword again, she closes her eyes silently hoping, pleading for someone, anyone to save her.

Hearing the sharp clashing of metal on metal, Weiss dared to open her eyes, and the sight before her was astonishing, their, standing before her was a man, his hair was just as white as hers, his skin was tanned, and his eyes were like steel. The man wore a strange white jacket that looked as if it was torn in half, underneath the jacket he wore a tight black shirt with sliver accents and a metal plate on his collar, and black pants that had two black straps on his thighs, and another two strapped around his shins separate from each other. He wears black metal plated shoes, which appear to be attached to his trousers.

In the hands of the man were two of the most exquisite blades Weiss had ever laid her eyes on, identical in shape with the only difference being their color. The sword in his right hand was black with a red hexagonal pattern, the other was by contrast a stark white with no pattern on the blade. The reason her eyes were drawn to the blades originally had not been to admire their beauty, but rather the fact those blades had stopped the massive sword of the massive knight.

Fate

The moment Shirou had been summoned he knew he had to protect the girl, who was now safely behind him, Shirou had traced his two favorite swords Kanshou and bakuya, without thinking he had placed himself in the way of a huge sword which had been aiming for the girl in white, he had stopped the gargantuan blade form killing the girl, but he knew that the only way to make sure she was safe was to kill this creature in front of him.

The twin blades struck the armor in the side sending it flying across the room, before it collided with the wall Shirou sped after it, with a yell his sword cut the monster's arm clean off. The knight crashed into the wall, causing a crater to form. Shirou leapt into the air while bringing his swords back, as he came back down so did his swords, with another crash the knights head fell to the ground.

Shirou turned to the girl and knelt before her "are you my master?" His question must have stunned her, for she did not say a word. He looks up at her, worrying that something was wrong "are you alright master?" The girl in white faint's but before she can hit the ground Shirou intercepts her decent by catching her.

RWBY

When next she awoke Weiss was in her bed, most would assume what happened was just a bad dream, but Weiss wasn't going to fool herself, she knew everything that happened was real. Getting out of bed she heads for the shower, but first grabs her favorite dress from her wardrobe.

Descending the stairs, she smells something amazing, now speed walking into the dining room, she spots the man who saved her, he was sitting at the table drinking a cup of tea. Once she takes a full step into the dining room the man sets his cup down and stands, he walks over to her, stopping just in front of her and asks only one question "are you my master?"
