XXXXXXXXXXX

Class: Saber.

Master: Kiritsugu Emiya.

True Name: Shirou Emiya (Unknown to everyone except himself so far).

Sex: Male.

Height/Weight: 187cm, 78kg.

Alignment: Neutral Good.

Strength: D~C

Endurance: C~B

Agility: C~B

Magical Energy: B

Luck: E

Noble Phantasm: ???

Thanks to a life full of training and combat, combined with a proper tutelage in magecraft, at some point in his life Saber became pretty good at Reinforcement magecraft, allowing him to boost his physical stats by one rank as long as enough Magical Energy flows through his veins.

Class Skills:

Magic Resistance: D

Even if Saber is a Magus himself, he is from an age where magecraft have reduced significantly, making his magic resistance pretty low taking in account his class.

Riding: E

At this level, Saber is only given basic knowledge about how to ride something. However, thanks to being from the modern era, he is familiar with most kinds of modern vehicles.

Personal Skills:

Clairvoyance: C

Allows clear vision of distant targets, and improves movement and vision.

Independent Action: B

Rare as it is, even if he isn't an Archer, Saber has Independent Action as one of his skills. That's due to the way he lived his life, while he wasn't completely alone like the Counter Guardian EMIYA, Saber's life wasn't that different from his counterpart's. At this level he would be able to stay in this world for two days without a Master as long as he doesn't use too much of his Magical Energy.

Eye Of The Mind (True): B

Allows calm analysis of situation and the enemy's abilities in spite of danger, and considering all possible actions in a particular situation. If there is even a 1% chance in comeback, this ability greatly improves the chances of success.

Magecraft: C

Unlike certain Counter Guardian, Saber received a proper tutelage in magecraft at the Clock Tower and later by his friend and lover, Rin Tohsaka. While his ability at most branches of magecraft is below average, he is much better than most magi at the few types of mysteries that doesn't require an Elemental Affinity such as Reinforcement or Runecraft.

The Crimson Saber

Chapter Three: A Madman's Revenge

Once Saber and Irisviel arrived to the Einzbern Castle it was already late in the evening, all the way to the forest had been devoid of life, absolutely nobody was in the streets of Fuyuki City. Seeing the town like that brought back distant memories to Saber's mind, those days patrolling the streets back in the Fifth Holy Grail War didn't seem so distant now.

No, he should focus on the way and not in the past, with his Servant body he would be untouched by a car accident but the same couldn't be said about Irisviel.

"You had a sad look on your face," A voice said at his right.

"Huh?" Saber asked, not understanding what Irisviel was talking about.

"That you had a sad look all over your face, is something that matter Saber?" Kiritsugu's wife asked in a voice filled with true concern.

"Err, no," He replied, feeling a little embarrassed at that she read his feelings so easily. "Just thinking about the past."

"I see," She paused, after a few moments she spoke again. "Say, Saber, what did you mean by 'nameless' when you talked to Rider before?"

'Ah, so she is intrigued by my name?', he thought. "Well, you can call me Shirou if you want, I don't truly care."

"Saber, you know I wasn't talking about that."

Saber sighed. "Well, I'm not really nameless, Shirou is truly my first name," She raised an eyebrow at that. "But there's no way that I'll tell you my whole name, not yet anyway." He didn't want to add more insane stuff to her life, and that the adoptive son of your husband happens to be his/your Servant is truly insane stuff.

"Why?" She asked in a curious tone.

"...Personal reasons," And he leaved it at that, though not before adding another thing later so quietly that she nearly didn't hear. "...Well, maybe after I use my Noble Phantasm." He was sure that after using Unlimited Blade Works someone would recognize him anyway. His legend might not be as known as others, but it was still there. And as the Throne Of Heroes doesn't have a concept of time...Yeah, you get the idea.

"You're the best, Sa-!" She paused to correct herself. "No...Shirou." Irisviel said with a gentle smile.

Were he his teenager self again Shirou would have blushed, but a life full of hardships have changed him, a lot. So, instead of having his cheeks turning into an unhealthy tone of red, the Servant Saber replied in kind with another smile.

"Ha, thank you...Iri."

He continued driving with that smile until they arrived to their destination.

(Scene Break)

"Master, I hope that you have found the information you were seeking," Saber said to Kiritsugu once he and Iri were inside the Castle.

"Yeah," He then proceed to share every bit of information he could find about the enemy Masters and their Servants.

So far he only found information about Archer's, Assassin's and Rider's Masters. Archer's was Tokiomi Tohsaka (Who Saber recognized as Rin's father), Assassin's was Kirei Kotomine, and Rider's was Waver Velvet, though he and Irisviel had seen him before.

With that information, Saber gained a new target. Kirei Kotomine was going to die at his first chance, he just couldn't let him live after all the things he did (Well, in this universe he hadn't done anything yet, but even then Saber targeted him anyway). While Shirou knew that Kotomine had been a Master in the Fourth War, he didn't know who's Master. Now he knew.

While Saber sat down thinking about future strategies to take down Kotomine and Gilgamesh as soon as possible, Irisviel and Kiritsugu were talking about something regarding the forest's Bounded Fields. Well, that was interesting. Deciding to pay attention at their conversation, Saber opened his eyes.

What he saw was Iri using a Crystal Ball of all things, and some place in the forest was reflected on it.

'So that's how Illya pinpointed our location back then.' He thought, recalling that particular day of his life. Age had erased some of them, but the memories of the Fifth Holy Grail War remained untouched in his mind.

"Shirou!" Iri's scared scream brought Saber back from his thoughts to Earth. It seemed like Kiritsugu wanted to ask something about the way that his wife was addressing Saber, but he didn't say anything as the Servant ran to their side and caught sight of what was going on through the Crystal Ball.

A man, if he could even be called that, was walking through the forest with several children alongside him. Those kids were obviously scared if the look of pure and true fear in their eyes was an indicator.

"I KNOW YOU'RE THERE SOMEWHERE! COME, AS MY REVENGE SHALL END WITH YOU!"

"Caster," Saber released a snort of annoyance as he realized who that man was.

"How can you be so sure about that?" Kiritsugu asked while frowning at the Crystal Ball.

"He is the only one who would want to take revenge in us," Surprisingly Irisviel was the one who replied instead of the Servant. "We burned his hide place, after all."

One could swear that Saber had been surprised for a moment judging by the change in his facial features, but it was so brief and unnoticeable that most likely nobody caught sight of it. "Yeah, that's right. Master," He then turned to look at Kiritsugu, as if waiting for orders. As much as he wanted to go and stop Caster as soon as possible, he couldn't just leave his Master and his allies alone.

"WHERE ARE YOU?! THIS CHILDREN WON'T WAIT FOREVER, O HERO!"

"Go," The Magus nodded at his Servant. "Maiya, Iri and I will leave in the opposite path. I'm sure you can handle Caster on your own."

"Understood, don't doubt in using a Command Seal to call me if things get bad." Saber then leaved, running through a window that was at the other side of the room at an impossible velocity.

"Couldn't he just use the door?" Kiritsugu sighed. Really, even in situations like this, the oddity of his Servant kept surprising him.

'Well, at least he's useful' He shrugged while walking to the door alongside Maiya and Iri, who had expressions on their faces similar to his. Oddly enough, Iri's was accompanied by a little smile.

(Scene Break)

Saber ran through the trees in order to cut the distance faster. During that he almost forgot that he didn't ask where Caster was. Without feeling embarrassed at all due to their current situation, he asked to his Master using their spiritual link. Thankfully he had been running in the right way, Saber didn't like the idea of him arriving late to save the children just because he forgot to ask for directions.

Thanks to his status as a Servant, he didn't need to reinforce his body to run at non-human speeds, his C rank agility made sure of that. However, little did he care about that, as he flowed prana through his legs to the point in which they were near breaking by the pressure. He didn't care. His Reinforcement allowed a boost to B Rank, and he was more than willing to exploit it if it meant that he had more chances in saving someone.

He stopped in the top of a tree when he caught the scent of what could only be Caster. His mystical awareness that came with just being a Servant combined with his almost unfair ability to sense prana allowed him to smell Caster with almost a hundred meters of distance.

He smirked. If he plays his cards right he might be able to take down Caster without him even noticing what killed him.

Tracing his long black bow, one that was made of a material that the current world haven't seen yet, he looked for the perfect angle to snipe Caster. In fact, while he didn't like the idea of being an Archer because that would make him even more similar to EMIYA, being an Assassin would have been perfect for him. It's not like he disliked his status as Saber, but Presence Concealment would have been an incredible useful skill for him, taking into account that sniping his enemies was something he usually did.

Oh well, there was no point in crying over the spilled milk, he would have to work with what he had and not think about stupid, 'what if' scenarios that will never come to be.

Now, going back to the main topic, which would be the best weapon for this shoot? Caladbolg II was out of the question, he wanted to save the children, not blow the whole forest. In fact, any Broken Phantasm won't do, as that would put the kids in unnecessary harm.

Hrunting was also out, the pressure alone generated from it would be enough to severely harm or even kill the kids.

Kanshou or Bakuya won't do either, even if the kids would be untouched, thinking that he could take down Caster with just those wasn't a good idea. Even if they have incredible strong anti-monster properties, as much as he disliked to admit it Caster didn't qualify as a monster. At least to the weapons' standards.

Gae Buidhe may have been a good weapon option, but he couldn't aim for any vital sport in Caster's body without harming at least one of the children in the way.

That only left one option. Gae Bolg, the barbed spear that strikes with death. Throwing it normally like Cu Chulainn would do wasn't an option, as the kids will be touched by the spear in its way. But shooting it with his bow he would be able to shoot it in an angle that would go right to Caster's heart, without harming no one else in the process.

'Let's do this'

"Trace On." As he chanted, the vague form of an spear made of Magical Energy appeared in one of his hands. Tracing spears had always taken more prana and time than swords, but it didn't matter at that moment.

After a few seconds, Cu Chulainn's spear took form on his hands. Just looking at it made him grimace recalling the time when he had been stabbed in the heart, but it was worth it if it would help him to archive his goal.

Placing it in his bow, he used Alteration on it, making it more aerodynamic. While it wouldn't fly as fast a Caladbolg II, thanks to the its form, it was more than enough.

Gae Bolg...Saber muttered as he let the spear/arrow fly, seeking for Caster's heart. However, it didn't end as he expected. Sure, it truly hit Cater's heart, and it truly killed him, but thinking that someone like Caster wouldn't have something to use in case that something like this happened was a huge mistake of his.

The moment Gae Bolg reached Caster's heart, the madman's body exploded allowing thousands of monsters, plus a giant one that covered at least half a kilometer just by existing, emerged from his body. Killing the children immediately. The only thing that Caster could say before dying was release an scream of "COOL!"

"DAMN! I should have expected something like this!" Saber cursed while running, in order to avoid the giant's attacks while dodging any little monster that tried to test their luck in killing him.

'Saber, what's going on?' Kiritsugu's alarmed voice asked inside his mind.

'No time to explain, are you and the others already out of the forest?' He replied in an annoyed tone. All of this was his own fault, after all. It was normal for Saber to be angry at himself.

'Yes, we are. Why do you ask?'

'Good, because I'm going to blow the whole forest.'

'What?! What is happening?!'

'Caster resulted to be more difficult to handle than I thought, so I'll have to bring the heavy guns. I'll explain more later'

Saber heard as Kiritsugu said 'Damn' and they stopped their conversation. There was no time to waste, the monsters will be out in the city soon if he didn't do this as soon as possible.

In his hand the form of Caladbolg II appeared, which she later put in his bow. Aiming at the gaint monster, Saber chanted.

"My core is twisted in madness, CALADBOLG!" By the time he let the Broken Phantasm fly, he was one kilometer afar from his target. His skill of Clairvoyance combined with the reinforcement in his eyes made him able to shoot from such a distance.

The whole forest was roughly three kilometers long, Caladbolg evaporated one of them. Including the Castle alongside Saber's target, the gaint monster. Nothing of that was left, not even a single tree was spared. And most likely all the little monsters were killed by Caladbolg too.

However, Saber wasn't going to leave anything at chance. Shooting sevaral broken copies of Kanshou, he cleaned all the zone killing every monster that somehow survived the explosion.

(Scene Break)

Meanwhile, outside of the forest.

Kiritsugu heard a loud sound coming from inside the forest, while his connection with Saber was untouched he wanted to verify that everything was alright.

Sending a brief glance towards both Iri and Maiya, who seemed to understand his intentions as they nodded, he concentrated in his link with Saber.

'Saber, what's going on?'

'No time to explain, are you and the others already out of the forest?'

Yes, we are. Why do you ask?'

'Good, because I'm going to blow the whole forest.'

'What?! What's happening?!'

'Caster resulted to be more difficult to handle than I thought, so I'll have to bring the heavy guns. I'll explain more later'

Remembering the fact that he could send his consciousness to Saber's body and see through his Servant's eyes, Kiritsugu did exactly that. What he saw surprised him. A giant monster was standing in the middle of the forest alongside hundreds more of little monsters.

And Saber was standing in the middle of it. Cursing quietly, Kiritsugu decided to see how his Servant handled the situation.

Saber run for a few minutes, dodging any attack that came in his direction until he for some reason stopped. Jumping at the top of a particular big tree, a black bow appeared in Saber's hands.

A bow? He will have to question Saber about that later . After all, you don't see a bowman in the Saber class every day.

While aiming at the monster, another thing took form in the Servant's hand. This time it was something that could hardly be called a sword, its form made it almost useless in a fight of swordplay.

However, Kiritsugu understood perfectly Saber's intentions with it. He was going to shoot it.

"My core is twisted in madness, CALADBOLG!" Were his consciousness in his own body, Kiritsugu would have felt as his eyes widened. While he was no expert in mythology, even he recognized the name 'Caladbolg'. Fergus mac Róich's sword, the one to said to be the Irish equivalent of Excalibur. However, Saber just couldn't be Fergus mac Róich, nothing about him matched with the Irish's legend.

Great, more things to ask about once Saber was back.

Back to Saber's point of view, Caladbolg had erased everything in its way. Destroying at least one kilometer of the forest, alongside the monster and probably the Castle.

And even then, Saber was not satisfied. He ran through the whole forest, continues copies of what seemed to be a sword in the form of a black wing were fired from his black bow killing any monster that was lucky enough to survive the previous attack.

He truly got a good Servant, didn't he?

(Scene Break)

Back to Saber's POV

"I can't sense more monsters, I guess I killed them all." Saber sighed.

Caster had been a pain in the ass to deal with, that was for sure. At least Saber was happy at the fact that Caster couldn't harm innocent people anymore, though his Master was another thing completely. Hopefully once he realized that his Servant was dead, Caster's Master would stop kidnapping children, but knowing his luck Saber was almost sure that things won't happen like that.

Focusing in his link with his Master, Saber ran to where he sensed Kiritsugu. It wouldn't be too much time before other Servants came to see what happened, and he would rather to stay near his Master, Iri, and Maiya (Even if he had barely talked with the latter) if something were to happen.

"Master, Iri, Maiya-san," He acknowledged all of them as he jumped from a tree to their spot outside of the forest.

"We have A LOT to talk about, Saber," Kiritsugu said in a really serious tone. "First, what's your true name?"

"Master, I already sa-" He started saying, but Kiritsugu interrupted him.

"Don't kidd with me, Saber. Iri called you 'Shirou', there's is no way that you don't remember your true name if you could come up with that one," He paused. "I'll use a Command Seal if I have to, Saber."

"Understood, go ahead."

"Huh?"

"I'm not telling you my name for both of our sakes, but if you want to know it so badly then go ahead, and waste one of your Command Seals."

"Hmph, very well. By the power of this Command Seal," His left hand radiated with Magical Energy. "I order you, Servant Saber, to tell me your name and your legend."

Saber felt as foreign prana invaded his body, forcing him to pronounce words that he didn't want to.

"I'm a Hero Of Justice, Shirou Emiya."

AN: Yep, here it is. I had planned to update it at the same time that starts the New Year, but then I remembered that I don't know when it starts in other Countries aside from mine (And most likely nobody in my Country aside from one of my friends reads this). And I guess that is time to to say from where I'm from.

I'm from Argentina! A Third World Country in South America that nobody gives a shit about!

I'm planning in moving to another Country as fast as I can...

Anyway, I'm not here to bore you with my stupid life, so let's get into the actual chapter.

It's a bit longer than usual, and I also included Saber's stats. In my opinion EMIYA's stats doesn't take into account his magecraft. If HF Shirou can use Reinforcement on himself thanks to Archer's arm (Or that's what I understood. If it isn't like that then I don't understand how he kept up with Saber Alter and Kotomine), then EMIYA should be able to do the same on himself.

If it wasn't like that then I think I came up with a believable excuse for it (The whole Rin staying with Shirou stuff, thing that didn't happen in EMIYA's life).

Also, did you like how I handled all the Caster thing? So far I kept close to canon, changing a thing or two, but after this chapter I have plans in changing the war completely. Possibly opening a sequel for the alternative Shirou that will come after all the changes I made here? Maybe I could do that once I'm done with this story.

Anyway, I'm talking too much. Hope you liked the chapter.

I'm still needing a Beta, as you can see. Most of my errors aren't just grammatical mistakes, but that I just don't know how to phrase something in English, if someone could help me with that I would be really happy.

My next update will be a re-write of the first chapter of 'Who needs when you have fire?' or the next chapter of 'With Wings And A Mind Of Steel', I'm not sure yet.

I appreciate all the criticism as long as it isn't a pointless flame, by the way. Just remember that I don't gain anything from this and that I just write this for fun, publishing it in Internet is secondary for me. I do it just because some people like it.

I hope you liked the chapter.

See ya!
