Fate's Tail

Author's note: I don't own Fate/Stay Night or Fairy Tail.

I've always wondered about a Fairy Tail and Fate/Stay Night crossover but no one would ever make one so I am having a go at it. I've only read the visual novel for fate/stay night but that was a bit ago so my info might be off. Then for Fairy Tail I've gotten to the part where lisanna appears and again my info might be off so sorry if it is. In the Fate/Stay Night storyline I'm not sure if I want to make this the good end of UBW or a hybrid between Fate and UBW. I've always liked Saber and this way I can add the Realta Nua ending into this if I want to.

Hope you enjoy this because this was such a pain to write and if you just write a stupid review it will be ignored since those are annoying.

Chapter 1

"My whole life was Unlimited Blade Works indeed." a man murmured as he stood overlooking the carnage that he had created.

As far as the eye could see, stretched a brown lifeless wasteland. The bodies of countless people lied on the ground in strewn about in various poses. Each body had a sword stabbed into it with a look of pain and fear that was etched upon their face. Blood slowly drained from their bodies covering the wasteland in a sea of blood.

The sky was orange from the setting sun, as if to show the battle was over. Clouds floated in the sky above unmoved by the site below.

The sight of the carnage would've caused many to become squeamish at the sight but the smell made it far worse. The smell of the countless dead bodies was horrendous and the smell became worse as the bodies slowly started to show signs of decay. All but the most experienced veterans would've been brought to their knees by the carnage but the man stood as steadily as he could staring without even flinching at what he caused. If one had looked into his eyes, one would of seen years beyond his age of experience behind them.

Blood poured from many of his wounds as he struggled to stay standing. Beneath him a pool of blood had started to collect as it ran down his body, soaking his clothes that hung by shreds. Wincing he looked at himself, analyzing the damage that he took during the battle. His armor was riddled with cracks and holes from the many hits he took. Underneath his skin, metal could be seen as it gleamed out. Twisting and turning, swords moved beneath his skin trying to seal the wounds but failing.

Breathing was starting to get hard for Shirou Emiya. He could feel his blood seep into his lungs obstructing the flow of oxygen to them. His vision became hazy as the lack of oxygen was finally getting to him.

Closing his eyes, Shirou thought back about the choices that he had made. Though he had no regrets he would always wonder if he ever had what it took to be an ally of justice.

A superhero…. Or an ally of justice. The dream that started had as a child. By meet with Kiritsugu Emiya that dream was born. Thinking about Kiritsugu brought many memories for Shirou.

Kiritsugu Emiya, the man that saved Shirou Emiya from the fires of hell and the man who became his adoptive father.

As a child Shirou had always admired his efforts to save the innocent. How he would give up his life if he had to, to save the lives of others. As he watched Kiritsugu, Shirou soon adopted the idea to be a hero for others. By becoming an ally of justice he would help the people in need and everyone would be happy.

But Kiritsugu knew the flaws of that ideal though and he tried to stop Shirou to no avail. Shirou would take that ideal as his own in life when Kiritsugu died though he would later learn the flaws of that idea.

Life is never as simple as we would want it to be. With every idea and thought there are positive things and negative things. With the ideal to be an ally of justice there are two major things that would contradict that ideal.

The definition of a superhero is a person who has the power to save the lives of others. In his life Shirou had dedicated his life to become a superhero to save the lives of others. But in order for him to save those people they would have to be in danger and for them to be in danger there had to be an evil that threatened them. So for his dream to be a reality, he would have to wish that there was an evil that threatened people. People would die for his dream and for his accomplishments to be a reality.

There lies one of the two flaws with his dream. For people to be saved, they would have to be suffering in the first place. Then would that make Shirou the good guy for saving those people or the bad guy for wishing that danger upon those people. It would depend on a person's individual thoughts to decide that. To Shirou that would make him the bad guy for wishing evil would strike.

Then there was a second flaw with his dream. In any movie the superhero always is able to save the lives of the people without sacrificing the lives of others. But Shirou wasn't like the superheroes from the movies. As Kiritsugu knew and what Shirou would later learn is that for every life saved there is always a life lost to save the other. No matter how hard he tried, Shirou always would have to have give up the lives of others to save the greater good. To save the lives of ten people he had to sacrifice one life. To save the lives of one-hundred people, ten lives would be lost. Then to save one-thousand people, one-hundred people would be lost. Always to save the greater good Shirou would always have to sacrifice people.

There lies the other flaw of the dream that Shirou follows. In the end a life would always be lost and though Shirou wanted to be the perfect superhero he knew that it was impossible. Though he fought for that dream he knew it would never be. Archer had told him that.

Thinking of Archer brought back many memories for Shirou as he thought back to the Fifth Holy Grail War. The Holy Grail War had taught Shirou many things and held many memories for him.

Archer…. The Heroic Spirit called EMIYA. EMIYA was one of Shirou's possible future selves from an alternate timeline that was called into the Fifth Holy Grail War by Tohsaka Rin. Tohsaka had used her crystal pendant that was given to her by her father as a catalyst to summon the strongest Servant in the war. She had hoped that by using an unknown catalyst that she would be able to summon a strong Servant. But she had made two mistakes during the summoning.

During the time of her summoning her clocks were off by an hour. So during the summoning she had thought she was at the peak of her power but she wasn't. Then she had thought that she had used an unknown catalyst but she was wrong. The catalyst used to summon a Servant would always have a connection with a Servant. From the past, present, future or even an alternate reality the Holy Grail would use its magic to pull that person to the time of the summoning.

The crystal pendant she had used had a connection to Archer. In an alternate reality Tohsaka had used the magic in that pendant to save the life of Shirou Emiya after his heart was pierced by the Lancer of the Fifth Holy Grail war. By using the pendant she had saved EMIYA's life when he was still just Shirou Emiya. After she had saved him she would forget the pendant by his side and EMIYA would find it. Then till the day he died he would keep that pendant by his side in memory of the person that he never knew who saved his life.

EMIYAs dream had started just like this time's Shirou Emiya by being saved by Kiritsugu. He had participated in the Fifth Holy Grail war of his time and won with his Servant. By winning the war his dreams to become a hero were encouraged and he would fight as an ally of justice.

Time would change that though.

EMIYA would live his life as a superhero just like he had dreamed. By following his dream he saved countless people. Though he would learn just that Kiritsugu was right and not everyone can be saved. For every life saved another was lost. Little by little he lost faith in his dream. But then there was a great calamity.

Making the decision to save as many people as he could, EMIYA had made a pact with the world. In return for power, he would become a Counter-Guardian. By saving the people before him, that was enough for EMIYA. Then he had thought by becoming a Counter-Guardian he would be able to continue serving as a superhero in death.

But things never went the way he had thought they would. The very people that he had saved from the great calamity betrayed him. They had branded him as the cause of the calamity and had him executed for a crime he had never committed. However, this didn't stop EMIYA. As a Counter-Guardian he would be able to save unlimited lives.

Then the very dream that he had protected from the criticisms of others betrayed him. The dream that he had spent his whole life trying to become destroyed him.

A Counter-Guardian is a protector of the world and humanity. EMIYA had thought that by becoming a Counter-Guardian he would be able to save the lives others. In death though, he would find out what it really meant to be a Counter-Guardian.

Though a Counter-Guardian is a protector of the world and humanity the way they achieve that is a twisted way then people think.

A Counter-Guardian is summoned whenever there is a factor that threatens mankind as a whole. They then appear to eliminate the source of that factor to save humanity as a whole and not any individual person. Never held down by morals and other feelings they might feel, they kill without discrimination innocent and guilty alike. A Guardian would even kill a child if that child had a chance to kill humanity.

As a Counter-Guardian, EMIYA would kill the lives of endless people instead of saving them like he had thought he would. Repeatedly he would see the mistakes of mankind and had to oppose his dream as a superhero to save the lives of mankind as a whole. Any person he saw had to die and as time went by he became bitter and angry at what his dream had done to him.

Longing for a way of release, EMIYA began to hope that he was sent to a time when Shirou Emiya was still alive and before he had made the contract. By killing his past self he had hoped to kill the dream of Shirou and to create a time paradox strong enough to end his existence as a Counter-Guardian.

Time would pass and he would continuously pray that his wish would come true. And he got his wish.

Summoned by Tohsaka Rin to be Archer, he came into the Fifth Holy Grail war when Shirou's dream would first start to become a reality. But at the time of his summoning, his memories as Shirou Emiya ceased to exist vanishing from his mind. Only some key memories remained like his meeting with Kiritsugu Emiya and the night when he had summoned his own Servant. With these memories and his own keen intelligence he was able to deduce what had happened and what he could do.

With the chance to end his existence near, EMIYA now Archer, would take every chance he could to kill Shirou Emiya. But every time Archer had tried to kill Shirou he was thwarted. The reasons varied from his own master stopping him to the Servant that Shirou had. But Archer would not be deterred and would continue his efforts to kill Shirou. But his close proximity to Shirou would only make Shirou stronger. Since Shirou Emiya and Archer are essentially the same person one's experience would flow into the other.

By being so close to Shirou, Archer's combat experience and magical knowledge would flow from himself to Shirou decreasing the amount of time it took for Shirou to get stronger. The greatest magic Shirou could possibly know that would of taken twenty long years to learn was learned in under a week by being so close to Archer though he wouldn't have enough magic to use it for a long time unless he had help.

But even though Shirou Emiya and Archer had started from the same origin and essentially the same person they were totally different. Time had taken its toll on Archer and he had come to deny his dream while Shirou Emiya would remain naïve and fight for his dream. While Archer had given up his dream as a superhero Shirou would continue to reach for the sky.

And though Archer was stronger, Shirou was able to convince him that he deserved to live. In a duel with Archer that pushed him to the limits, Shirou prevailed and won. In a defeat that he accepted, Archer would leave hoping that Shirou wouldn't turn out the way he had.

And in time Shirou would get stronger after the war. Striving to become the superhero that Archer wasn't able to be, Shirou trained himself beyond his limits in the hopes that he wouldn't be like Archer. With the help of his Servant and Rin, Shirou was able to go beyond his limits and surpassed Archer.

Then the calamity that had destroyed Archer's dream came to pass. Many people had died during the calamity but Shirou survived and helped everyone to the best of his ability.

Time would change Shirou in many ways. The body that he once had had changed after years of projection. The hair that was once orange had turned into a bright white and his eyes that were once black were as grey as steel. Then Shirou used the same equipment that Archer had when he was a Servant. Everything that was used by Archer only made Shirou stronger.

Shirou's personality wouldn't change much though. Though he wasn't the happy going kid that he used to be, he still had that childish part of him that made people love him.

Years would pass and Shirou would continue to fight as an ally of justice. Friends left during that time and soon only two stood by his side but then even they disappeared. Alone, Shirou would fight until this day when he was defeated. Alone and outnumbered, Shirou would fight and win only to succumb to his wounds.

Which was where he was now as he stood alone on that hill of swords. Blood trickled out of his mouth as he started to cough. The pain that Shirou had once felt had finally disappeared and his body was numb.

Everything was now dark to Shirou as he felt his life slip away. But he still had one thing left to do. He still had to search for the one he loved though the odds were against him and though the odds were against him, Shirou would never give up.

"Sa….ber"

Falling to the ground, Shirou closed his eyes and let the darkness take him. Only to feel a tug.

Well that's the end of chapter 1. It took forever for me to be kind of satisfied with this but this is the best I feel I could get it to be. No idea when the next chapter will be out but I hope that it will be soon.
