He is Steel, he is Sword. A blade forged in the fires of a hell with no equal. But, he is also a Scabbard, the sheath of a weapon meant to protect. For him, he will become, no matter the cost, a Hero of Justice, to save all he can. This is the Sole Emotion he has.
However, that is second to his desire. For he seeks something greater than being a hero, he searches till the end of his days for the blade that he is meant to be with.
He searches for his lover.
He searches for his Saber.
And nothing, not in any land, world, or realm. Will stand between him, his ideals, or the one who will always wait for him. So it doesn't matter if he is brought into this new world, it doesn't matter if it is no longer humans he will be saving. As long as he can save as many as he can while on his endless search, that is all he can ask for.
Everything happened at once, after the defeat of Discord, it all seemed peace would reign. However, as the Canterlot Wedding was preparing for its event within a few days, the Crystal Empire appeared. Then, Tirek escape a few hours afterward. Suddenly, different villains began to pop up everywhere all over the nation. With the Equestrian forces, heroes, and Princesses spread out to try and keep back the villains, Canterlot City was overtaken by the Changeling forces.
All hope seemed lost, surely this was the beginning of a slow and painful death for Pony Civilization.
Until, in the midst of fires within the once proud city of Yanhoover, a strange being appeared.
A Fate/Stay Night crossover with My Little Pony: Friendship is Magic. This Shirou Emiya is from the first of the routes, the Fate route, with few elements of the recent Unlimited Blade Works anime included. And really, don't Dislike for the pairing alone, that's just cruel.
