Prologue

Heroic Spirit EMIYA. Counter Guardian. Wrought Iron Hero. "Unknown to death. Nor known to life". Was feeling depressed and wished he could feel nothing at all. And in all honesty, he was damn close to it. Alaya sent him on another massacre. One trillion people. Weird. Because that number is usually lower. Granted the death toll is still around two billion every time. "Unknown to death. Nor known to life."

Flashback

"I'll do it. If it means no one has to cry."

Flashback end

Three years later

"EMIYA. Go to South Africa and wipe out _ City. A mage is too close to the Root for my comfort especially for his reasons. Now go." He appeared a few miles from the place he was supposed to destroy. While he was technically a heroic spirit, he could get to where he needed to be in a split second, he chose not to. He needed some time to prepare himself. He never got used to it. All the death and destruction. It haunts him regardless if he's awake or asleep. And it's not like Alaya would give him a break to begin with. Accepting the fact that there was no way out of this, and that he should get this over with, EMIYA looked at the town below him and thought about how to do this. Excalibur was out of the question. He would never forgive himself if he used his lover's weapon for something so horrible. Not that it mattered though.

Flashback

"I saw hell"

End flashback

He conjured his bow and the twisted sword Caladbold and said, "I am the bone of my sword. Caladbolg!"His job was almost done. Now he needed to look for survivors. Thankfully, there were none. One of the worst parts about this job was having to kill someone who couldn't fight back. While no one could stop his "arrow" he meant that he hated killing people that didn't need to die.

Flashback

"I saw hell."

Flashback end

"North Korea is about to do something outrageously stupid. Kill everyone at the silo and in a five mile radius." Once again, EMIYA prepared himself for hell. EMIYA, not paying attention, had to dodge a bullet because Allay put him right in the middle. "*sigh*Could be worse." Summoning Kanshou and Bakuya, he sliced through maintenance teams, soldiers, guards, scientists, the whole nine yards. And he did this the whole way out. He hated this part of the job more than anything. Killing people up close. When he blew up that town, he didn't have to see everyone's terrified faces before they died. Three hours. Three long hours of nothing but kill, kill, kill. Until he got out. By this point, there was nothing left of him. As he once told his former self, "This world of swords is all that I have." Now, he felt no emotional pain. Only physical. He looked around. Now runaways. Good. Alaya wordlessly confirmed that. But for some reason he was still here. No problem. The "man" if you could even call him that. He is like a machine. After all, "My body is made of swords." He walked over to a tree, sat down and waited for the world to take him.

Flashback

"And for the first time, I saw hell."

Flashback end

"Here again? I shouldn't be surprised. It's only happened a few million times and will only continue." EMIYA found himself back on his favorite rock in this reality marble. And sat there, waiting for the next round of hell.

Kischur Zelretch Schweinorg. The Wizard Martial. Master of the Second Magic. The Troll of Trolls was feeling ambitious. He had trolled many people in the past. Some came out alive and others didn't but that's not the point. During a little incident with Holy Grail War, Zelretch learned about the Heroic Spirit EMIYA and everything that happened to him. While Zelretch is a troll and sometimes an asshole, he's not a bad person. And besides, why troll a human, when you can troll the world itself. "Alaya. Here I come. I hope you can handle what I'm about to show you". Oh yes. It's win-win. EMIYA becomes happy again, and Zelretch gets to perform the ultimate troll. After all, what happens when the world cries?

After Zelretch looked in many places, he finally found it. The place where Alaya was keeping EMIYA. He could help but grin in anticipation. "Hello Alaya." Even though Alaya had yet to physically manifest herself, she still spoke. "Kischur Zelretch Schweinorg. We both know this isn't a social call, so what is it?" Zelretch knew he needed to word this carefully to not screw up and miss his chance. "Tell my Alaya. Do you know what it's like to be a counter guardian?" Zelretch said with a smirk. "To be a slave to the World?" "What are you getting at? Are you implying that my knowledge is incomplete?" She finally said after coming out in the form of a young girl with long brown hair who had dark blue jeans and a cute T-shirt. And what Zelretch assumed to be mid B breasts. "No, of course not. You know everything about humans. But do you know everything about guardians?" He said with a face that promised trouble. But here's the thing. She looked interested. Alaya was the unconscious will of humanity to survive and thus has similar traits. One of those being a thirst for knowledge. "Now Alaya. You will get into his head. Feel his every emotion. No matter what it is." At this point that vampire was grinning like a madman and Alaya was not liking it. But she thought she could win this. Nice try. "Start from the moment he signed the contract." She nodded.

Flashback in Alaya's point of view

"I'll do it. It means no one has to cry."

A few hours later

Caladbolg point blank. Crane wing attack. And trace over edge. EMIYA eliminated all the heroic spirits who were a threat to humanity. Yes, they would be back sooner or later but that was the nature of heroic spirits. You can't kill what's already dead. "Interesting." Shirou wandered around the world, helping and saving anyone and everyone he could. South America, Irac, Afghanistan, and many more war torn places on the planet. He would fight for whichever side he believed to be the better if no faction was worthy, he would save as many as he could. And he did it. He saved more people than he could have imagined. He bought this miracle with life and soul. Everytime, he was fast enough to perform CPR. Every time, he was fast enough to stop the bleeding. And every time, he was fast enough to stop that bullet. And without warning, Alaya was assaulted by flashbacks of him being able to do all of those things. And the emotions he felt.

Flashback in flashback

"I did it. I finally did it." Shirou said with relief. When my father saved me, I always wondered if I could smile the same way he did. And now I have. Taking a bullet to the arm wasn't fun but that's okay. Because John was saved.

Different situation

"Damn it! I wasn't fast enough!" Shirou knew he was in deep trouble. The man in front of him was shot in the chest and he didn't hany any medical supplies nor did he know how to stop that kind of bleeding. "Okay Shirou. Calm down and call for help." Shirou used his undershirt to plug up the hole. "This is Shirou Emiya from Squad 5! I need an Evac right now and I have wounded!" He repeated this three times. "Damn." The good news was it didn't hit anything vital but the bad news, was it expanded inside of him and caused more bleeding than normal. Shirou tried to pull the bullet out of him using project tweezers. And it worked. But he could only hope he didn't do any more damage. And as if by a miracle, the bleeding started to slow down and the man was still breathing. He'd lost a lot of blood so the fact that the bleeding slowed down a lot is a good and bad sign. And as if my another miracle, help finally arrived. This man was saved. "You're Shirou Emiya right?" "Yeah?" "Good job kid. Most people wouldn't know what to do and panic. And judging by the fact that he's still alive means you did something right. Come one kid. Let's go" And with that, they got on the chopper and flew back to base.

End flashback in flashback and flashback

Alaya was silent while a certain vampire was laughing and grinning like a madman. "That wasn't funny!"Wait? Why did I say that? These are EMIYA's memories and feeling so does that mean the bastard wants me to feel them as well?" Soon after, she had an epiphany. He wanted to troll her. To make her suffer. And for that she wanted to punish him as well. But at the same time, she wanted to see more. More of the sad and tragic life of Shirou Emiya. And that moment, she came to a stunning realization. She twisted him. Exploited him, and might as well have murdered him. All he wanted to do was save people. And I twisted and manipulated him into becoming a killing machine. "What have I done!?" She turned to Zelretch. "Zelretch, you bastard! You wanted me to feel that!? Why?!" "Because I wanted you to go through the same hell you put him through." On the outside, Zelretch was serious. But on the inside, he was happy as could be. Alaya was mad. And who, he had a pretty good idea but no definitive answer. But that's okay. He'll find out sooner or later. "Next you will see the last war that he fought in and how he was betrayed."

Flashback Shirou POV [This chapter is ½ prologue ½ experiment so there will be some inconsistencies. Hang in there with me]

I slowly walked around the camp looking for the commander to at least someone or something related to that. And along the way, I noticed children playing around and having a good time. I honestly wish I could be like that. But I knew it was impossible.

I am the bone of my sword

With Alaya and Zelretch

"What's that supposed to mean?" Zelretch explained. "He's talking about how he's too broken to be able to experience the same happiness. And his life will hardly ever be fun. The, I am the bone of my sword, part, talks about how he will always fight even if he breaks. A sword is meant to be used. And it provides a small healing ability when things get dicey. No on with the show!" Wonderful… But deep down, she wanted to see more. But little did she know, she will regret for the rest of eternity.

Back to Shirou

Five minutes. Five minutes was all it took for people to start staring at me. But different ages had different reactions. The older ones looked wary but the younger ones looked at me with curiosity and a little aw. For better or worse, I was only half paying attention so I bumped into a kid and due to my size, he fell right over. I knelt down so I was on his level. "Hey. Are you okay?" He seemed nervous now. "It's okay. I won't hurt you. Here, have an apple." He hesitantly took it so I gave him a kind smile "See? You have nothing to be afraid of. Now I'm going to give you more apples but I want you to share them with your friends, okay?" "Okay." I watched as the children ate for the first time in what looked like quite some time. I smiled a sad smile. I was smiling because I made someone happy yet again. But I was sad that one of the many cold, hard truths in this world is how someone always has to suffer. No matter who or what it is.

Steel is my body and fire is my blood

With Alaya

They stood in silence. But the old vampire was not the one who was sad. Rather, he was happy that she was finally learning her lesson. As it slowly dawned on her what she did to him. "I'm crying...and I know why...Damn it, why!?" She shouted as she looked up into the smog covered sky with gears floating in the sky. Representing his eternal slavery. Realization number two...She ordered him to kill one trillion people. That's not a massacre, that's genocide! She fell to her knees, not caring how the ground burned through her pants."Do you want me to stop? Or do you want more? Alaya was in deep thought. One one hand she was curious. On the other, she was terrified of what would come next. But I'll do it. I have to. EMIYA went through hell beyond comparison. And it's all because of me. So now it's my turn. "Please...show me more. EMIYA went through hell beyond comparison just so he could protect humanity, So not it's my turn." "I see you learned your lesson. Good. But are you sure? What happens after the war is far worse than what you just saw." For the first time in her life, she gulped in fear. "Show me more. Show me the hell the EMIYA had to endure." And with that, Zelretch threw her back into the life of the heroic spirit EMIYA.

Back to Shirou POV

"Alright men. The final battle if approaching. This will end one of two ways. 1. We take the capitle with minimal losses and celebrate our new found freedom. 2: This is a one-sided bloodbath. But know that win or lose, you can die knowing you fought for what was right and didn't die like a coward. Now onwards! Our plan is to storm the city from the air. Thanks to our good friend Shirou here, their AA units are...unavailable. And don't worry about civilian casualties. Everyone was safely evacuated to the surrounding towns where there's next to no one to oppress them. Let's do this!" It was a sound plan. But no plan survives the enemy. I should know after fighting in the 5th Holy Grail War of Fuyuki. And I don't know how or why, but I feel like something is going to go wrong and I shake the feeling. Oh well. I'll just have to ignore it until the time comes for me to act. With that last thought, he loaded up on the chopper and headed for the battlefield.

"Alright men. In two minutes, we'll touch down in the center of town and when you do, I want you all to spread outward. Remember, even though they're expecting a suicidal ground assault, it won't take long for them to catch up to us in the center of town. Check your shots and survive this mess." "Sir! We're approaching the LZ." "Good. 5...4….3...2...1...GO GO GO!

I have created over a thousand blades

To be honest I wasn't really paying attention but I knew what he said. I jumped out and ran right towards the border while killing as many peacekeepers(hunger games) as possible. No one saw me project and reinforce my swords. Everyone always wonders why I fought with swords instead of guns but you can't deny the results. Anyway, things were going well at first, but then all of the sudden, it looked like hell was raining down on us. First, underground explosives that someone remotely detonated. We lost a thousand men to those bombs. Next a firestorm from what I think was artillery. More men died. And then nothing. The screams died down, but I knew it wasn't over. And I'll be honest, I think it's a God Blessed miracle that there were any survivors. Much less anybody in one piece. And then we heard it. The sound of an army coming right towards us. I could easily take care of this, but I don't want to tell everyone why this city is now a crater. Gaé Bolg. It's have to do. While I don't think It'll do as much as Caladbolg II, I'm about to find out. I was able to jump on top of a building without anyone noticing. Okay. Here goes nothing. "The spear that never misses. GAÈ BOLG! I waited for what seemed like hours. Even though the explosion was quick, I was waiting for everything to come crashing down on me. But it didn't. For once, my E-rank luck held out for me. Silence. That's it. Miles and miles of pure silence. It was like the earth itself had nothing to say at the moment. Of course, I could only hope no one saw me throw a mythalogical spear or the Mages Association would have my head. But judging by the fact that no one is looking at me, I should be fine. I fell to my knees in exhaustion. That spear was a noble phantasm. And those things weren't exactly mana and prana cheap. Granted I've been forced to do more during the 5th Holy Grail War, a noble phantasm is a noble phantasm. Not cheap. But thanks to Alaya, I have a lot more mana and better magic circuits.

Unknown to death, nor known to life

Footsteps. Weird. I thought everyone was still down there. Next question. How did they get up here. I'm on a badly damaged skyscraper that could fall at any moment. Oh well. I would survive. Reinforcement. I love that magic. "Are you Shirou Emiya?" "Yeah why? Come with us. The commander wants to see you." This is bad. The last time that man wanted to see me I was almost killed. And after causing destruction of that magnitude, I think now he might have a reason. But if this is how I die, then so be it. "Okay. Let's go. May I ask why he wants to me?" "I'm not at liberty to say." Great. Two options. Kill these guys and run. Or let myself be killed for something I may or may not have done. Letting my, "Save everyone" philosophy get the better of me, I chose the second one. Time to die I guess. I had good run. I saved a lot of people. And now it's time to save more.

I have withstood so much, pain in order to have created so many weapons

The commander's office was bigger than my living room. And I lived in a fucking mansion. And that makes me wonder where some of the funds for this little rebellion go. Looking around I see commander Jerald Miles sitting in his really expensive chair that makes me wonder if he's as corrupt as some of the people we were fighting. But I knew there was only one way to find out and even though it would only be too late once I had the rope around my neck, I still choose not to fight back. This is my fate. And I won't fight it. Finally, the slime ball opened his mouth. "Hello Emiya. Do you know why you're here?" "No I don't sir." "Then let me explain. You are being charged with creating the whole mess and we have proof." He pulled out pictures of "me" at certain places making it look like I tried to start a war and succeeded. "Is this you, you war starting bastard?!" It wasn't me and I knew it. I've never met this man in my life and I don't even know where that is. But there was no use. "Yes it is, sir." "I thought so. Guards! Cuff him. And take him to the gallows." They royal guards shoved me to the ground and handcuffed me. 'Well this is it. Rin, Sakura, Fuji-nee, Saber, Illyia, I'm sorry I couldn't keep my promise.' "I hope you've said your prayers because you're gonna die soon. Now step on the platform.

Yet these hands will never hold anything

Even now it wasn't too late to escape. I had the power to kill everyone here and it would be a long time before anyone was any wiser. But I knew what I was getting into when I tried to become a hero of justice. No matter what kind of hero a person is, they always fight and die in some obscure way and it should disgust me. But it doesn't. Is it because of my acceptance of death? Or because I simply don't care? I don't know anymore. All I know is that I'm about to fulfill my end of the bargain with the world herself. She gave me the power to never be too late. But in exchange, I would spend the rest of eternity as her attack dog.

So it then, and I pray

"Shirou Emiya. You are being charged with high treason, desertion, war crimes, and the mastermind of the conflict. How do you plead?" "Guilty." "Then you are hereby sentenced to death. Do you have any last words, 'hero'?" I remained silent. Suddenly, I felt the floor beneath my feet disappear and the rope around my neck tighten. But I didn't fight it. I didn't even gag. I feel my life force slipping away. 'Goodbye everyone. I just wish I could see you one last time.'

UNLIMITED BLADE WORKS

Life if EMIYA end

"Make it stop! Please make it stop! It hurts. Help me, please!" Images of dead bodies and endless flames assaulted her mind and the pain of being hanged were too much for here to handle. She was on her knees holding her head. Or at least, the one she made for herself. Zelretch decided she had, had enough. And knew he needed to snap her out of it. But this wasn't his work. He pulled her out of the "movie" she was in. This was all in her "head". "Alaya! Stop! It's not real! It's just a memory. It's okay! You're safe, no one can hurt you even of they tried!" Her vision was hazy. The pain and suffering went away but the crushing emotions known as regret and guilt did not. She launched herself into the old vampire's arms. Or at least, tired to. With such poor vision she would have missed by a full six inches but the old "man" knew this was not the time to play the asshole. "shshshsh. Everything will be okay. Let it out. No matter what happens, EMIYA can't see or hear us. I made sure of it." She understood now. So this is what it's like to be a counter guardian. Most of her guardians were people who liked killing and Alaya thought she could put it to good use. Smart. Cuts down on the emotional strain you won't end up with x amount of EMIYA's. So to speak.

Hours past and even though she stopped crying, she was still a girl who just saw a hell she was not prepared for. 'Time to get this show on the road.' "Are you ready to talk?". "Y-yeah. L-let me s-see hh-him." "Okay. But promise me you'll send him to a world where he'll be happy. "Anything. I'll do anything for him. The same way he did anything for me." "Then come Alaya. We have work to do." It was a long walk to where EMIYA was sitting. She could just ditch the body and teleport there and resume her form but she needed time to think about what she was going to say. She was not going in there half cocked. But she noticed something. All the swords were stained with blood and instead of clouds, there was smog. Instead of dirt, there was ash. Not hot enough to burn anyone but ash nonetheless. And these gears. She would have to ask him what they represent. One of the many thinks she needed to say. With a deep breath, she steeled herself. "I'm ready. I can only hope he doesn't attack me."Alaya might be unkillable, but she can still feel pain. "E-EMIYA? Can we talk?" 'This is new. Something's not right and I wanna know what. Sense when does the world herself get nervous, let alone have tear stains on her cheeks? And OH SHIT! WHAT IS HE DOING HERE?!' "Okay Alaya, Zelretch, explain! Now!" She lunged at him and hugged him "I'm sorry. I'm sorry, I'm so sorry. Over and over again, I forced you to clean up messes humans made. Over and over, again I took advantage of your old ideal. Over and over again, I tortured you and turned you into a killer. I'm so sorry." EMIYA was at a loss for words. 'Did the old vampire do this? What in the name of the Seven Unholy Hells did he do?! Show her my memories?' "Zelretch, that was mean. Don't get me wrong. A little revenge would be nice but I don't believe in emotionally breaking someone. No matter how cruel that person may be. "I know you no longer have emotions and if you do, all you feel is hate and anger. Please let me fix that. I can send you to a world where you kill monsters instead of humans. I'm humanity's conscious will to survive, I can do anything. Please give me a chance!" He was silent for a few moments. Alaya, this'd better be good or you'll pay for this. "There's a world called Remnant where humans and faunus are at a constant war with monsters called grimm. Your job would be to make sure humanity lives to fight another day while killing as many as you can. And regain your lost emotions. I'm sorry I wish I could do more..." EMIYA wrapped his arms around her and drew circles on her back. She was so beautiful was she wasn't sending him on massacres. He thought for a moment. "I'll do it." Meanwhile, the old vampire looked like he was about to do something stupid. "And you. Try anything and I'll make it a very long and painful eternity for you." "Oh fine. I won't turn back his clock or anything like that. Now go. You have work to." "Good luck hero. I believe you. You still have people to save." And with that, heroic spirit EMIYA arrived in the world of Remnant.

"So this is Remnant." *growl* "And that must be grim. Alright bastards, let's DANCE!"

So what did you think? Should EMIYA be a teacher or a student? Gaia will not exist, making his weapons harder and more powerful. Will fallow canon. Pairing?

EMIYA and Ruby?
EMIYA and Yang?
EMIYA and Blake.
EMIYA and harem? Sorry but I can't see him with Weiss.
