Hi readers

So, yeah, this crossover right here… it's been sitting in my computer for months, see I haven't been able to upload my other crossovers because… well, basically, because even though I want to write and I know what to write, the words just doesn't seem to want to come out, so instead of staying without writing anything I decided to write another crossover, don't know if it was a good idea but, hey, why not? Originally it was going to be another crossover but since I like Fate and KH, I decided to use them.

In any case, hope you enjoy this first chapter and you know the usual, constructive criticism is always appreciated and I hope you forgive my bad English.

P.D.: I'm making Sora a bit more powerful since I want him to be able to at least fight and beat some Servants.

I do not own Kingdom Hearts or Fate/Stay Night they belong to Square-Enix and Type-Moon respectively.

"Wha-? Where am I?"A spiky haired young man asks to no one in particular.

However he was no simple human, he was Sora a hero chosen by the Keyblade to protect the multiple worlds in the universe, but right now he finds himself in quite the problem...

Sora POV

"Uh... What's going on?" I ask groggily I don't remember anything...well, let's see... I was in Radiant Garden...I went there because Heartless had been appearing there recently and then I... I... *trob* *trob*

"Don't you have a wish you want granted..."

"Trust the Grail..."

"Die... Die... Die..."

Ugh... What were those voices...? I... don't remember clearly, actually it kinda hurt when I try to remember anything else... Oh, well let's do some recon for now.

(Some minute later)

Well this looks like a mansion, a really thorn down mansion, there's something else to this... A faint sweet scent. It's coming from up stairs, something tells me I shouldn't go up, but then again my instinct have gone wrong sometimes; I'll go check it out.

As soon as I arrive at the second floor I keep following the sweet smell, until I find the source of it and I don't like what I see...

A girl in a brown suit and short magenta hair covered in blood and with her left arm severed... I rush and kneel beside her in panic.

"This is bad... This is really bad..."It not like I have never seen blood before but I'm not panicking because of the blood but because of the fact that I can't do anything to help her, she looks barely alive but not for long. She won't make it to a hospital and my magic won't be enough, but... I have to try...

"CURAGA!"I yell at the top of my lungs as I summon my golden and silver keyblade, but something unexpected happens.

Magic start flowing out of my keyblade in torrents like never before, a weird green circle with strange symbols appears around the girl instead of the usual green flower, however that's not the most surprising thing that happens.

From the part were the arm was cut a thin green line appears moving towards the severed limb, when they connect the arm starts to slowly move trying to return to it's rightful place.

(Some minutes after that)

Okay... She seems better, the bleeding has stoped and the arm has started to connect to the shoulder once again... The green circle is still there so the healing hasn't ended just yet, and while it was a weird situation, I'm not complaining, I was able to save her so that's what it matters... Guess I should leave for now, I still don't know where I am... So for now I'll keep doing some recon of this world, also I can feel a weird aura coming from someplace not too far from here, I doubt it's a heartless but better safe than sorry.

(A trip to the city and some minutes later)

Um... Well it looks normal enough, there are two parts to this city connected by a bridge, right now I'm in the part of the city with a lot of Japanese looking houses build in a hill, there is nothing really special about it except… maybe the great concentration of magic energy in the air, that must have been the reason my spell went all haywire in the mansion, but that's all, still I can't shake the feeling that something is out of place here... Hum, maybe I should just return to see how that girl is doing. Just then I hear the sound of battle from a house up in the top of the hill, it's faint but I definitely hear it, I don't think it twice before engulfing my body in an aura of light and start bouncing in each wall of the road moving towards where I heard the sound.

I arrive there in a few seconds, a classical Japanese house, I start running since there is no place to keep using "flow motion" as I get closer to the sound, I find them, a guy with red hair moving towards a shed in the backyard and a guy in, blue full body thighs with silver shoulder pauldrons carrying a red spear. The guy in blue is about to pierce the other guy. Now I may not understand what's going on but I know it's wrong to attack someone who can't even defend himself. So I launch at the guy in blue, my trusty kingdom key keyblade appearing in a flash of light in my hand just in time to block the red spear, after that I throw a fire spell at the guy with the spear, he blocks it but I manage to send him a couple of meters away.

"Hey, are you alright?"I said to the red head.

He nods "Okay, take cover for now" He does as I say and enters the shed he was going towards before.

"Did you finish talking?" the guy in blue ask in a mocking tone completely recovered.

"Yep, thank you" I reply in the same way.

Without another word, he launches at me with amazing speed, spear and keyblade clash sending sparks into the night.

He seems surprised I blocked his attack but that doesn't stop him from continuing his attack, I manage to keep blocking his attacks but he' s fast and I won't be able to keep this up for much longer... Well, guess I better make use of my brand new powered up magic.

"Protect" I murmur as the Reflega spell appears around me.

However the spear user keeps attacking without giving the shield much thought, normally the shield would have broken due to the extreme strength of the thrusts, but this time is different, the shield doesn't give in, the shield explodes around me sending the blue guy some meters away.

"Well, at least you know how to put up a fight" he says with a relax tone "But that magic... You're not Caster, I have already seen her and I doubt you are Saber your sword style is way too rough."

"Hey! I'll show you who has a rough style!" I run towards him and start focusing energy into my keyblade, he takes a defensive stance with his lance however before I even reach him, I leap into the air "Ragnarok" I murmur before realizing the energy inside my sword in the form of multiple projectiles that strike him head on.

"Well, well, well you have some tricks up your sleeve, don't you kid? But since I doubt you are a Master or a Servant, I'll have to finish you here… at least you fought back so I won't feel too bad about killing you" The blue haired guy say with a serious expression.

"… ?!"

"This battle is over... Gae..."

He suddenly rushes at me spear pointed directly at my feet, I put up my magic shield again...

"...Bolg"

But right there I feel it, my shield can't stop his next attack. My only chance it's to dodge, but can I still do it?!

Shiro POV

W-what is this?

Those guys doesn't seem human, well one of them saved me but...

No, if he were trying to kill me he had no reason to start fighting with the spear wielder...

*CRASH*"Argh!"A voice rings outside the shed, I move towards the door to see how the fight is developing...And I don't like what I see.

The guy who saved me wounded, with a bloody arm completely pierced, his key-like weapon laying in the ground some meters behind him. He turns around in an attempt to retrieve it, but Lancer is faster and gets to the key-weapon before its wielder.

He steps in the weapon destroying any hope of his user to recover it, the guy who saved me is in his knees, spear pointed at his heart, I can't let this happen, I won't let anyone die for me, but... What can I do?!... I... I...

Suddenly the mark in my hand starts shinning and burning, as a bright light engulfs the shed.

"Are you my Master?"I hear a female voice say...

Sora POV

This is not going so well, my left arm feels numb and I'm about to die.

I underestimate this guy, even though he got surprised when I dodged his *Gae Bolg* attack he didn't stop... *ugh*I really don't want to die, at least not without knowing why I am even here?! But...

Sudenly a bright light start shinning from the shed. He's distracted, I don't care what that light is, but I won't lose this chance.

I retrieve the keyblade from under his foot making him lose balance I stand up fastly and cast a stopga spell, luckily the time magic works, I reinforce the blade of my sword with light and make three sword slashes at the unmoving enemy, then I once again surround my body in a white aura and start spinning around him and finish my attack by throwing him to the other side of the backyard.

After I'm finished I cast a curaga spell on my arm, but even with this new acquired power the wound start closing slowly… Actually, why do I have another wound on my shoulder? When did I…? *throb* *throb*

Agh! ...This headache again! …I doubt I'll be able to fight against him again with only my right arm; hopefully he won't be able to keep fighting after that combo.

Sadly my hopes are crushed when the guy in blue stands up, he's not unscathed, actually he's bleeding but he still moves towards me spear in his hand and a grin in his face, I fall to the ground on my butt exhausted, but another ray of hope appears, in a flash a blonde girl in a blue dress with an armor, attacks my enemy with some kind of invisible weapon he feels threaten so he retreats, just as that happens the guy with red hair comes to my aid.

"Hey, are you okay?" he asks

*nod*"Yeah, just a bit tired..."I try to stand up but fail in doing so, luckily the red head catches me before I fall again "Thanks..."

"I should be the one saying that..." however our conversation is interrupted by the two strange figures talk.

"So, you're Saber..."the guy in blue says

"Who knows? Maybe I am, maybe I am not?" She says with a slight smirk

"Heh..."he chuckles dropping his battle stance "Well, I'm not about to have another fight with a swordsman this night"

"Are you escaping?" The girl says without lowering her guard

"Please, feel free to come after me, believe me I would stay but the Master I have is the worst" he then turns and points his spear at me "What's your name, kiddo?"

"...Sora" I say standing straight

"I'm a Servant from the Lancer class, be sure to heal that arm of your before our next meeting I have high hopes for you" he says with a slight smirk before disappearing.

After he's finally is gone, the blonde girl approach us.

"Ah, thank you, you saved us" I say bowing slightly

"No, I should be the one thanking you, since you saved my Master" She says in a caring tone

"Master? What's-?"I turn to the red haired guy but we are interrupted by a change in the aura of the girl.

"Master, please heal me" She states

"Huh? Wait; at least explain yourself a bit…"

"There is no time the enemy is already here"

"What, another one!? Well there is no way I can use such a difficult magic"

"I see, well another battle shouldn't be that hard even in this state" after that she simply leaps over the wall towards the street.

"Let's follow her" I say to the red head as I let go of him and start running towards the door to the house, I would have leap over the wall as well but it seems I'm quite tired, healing that wound sure is hard.

As soon as we exit the house the street is empty except for three figures in the distance the blond girl in silver armor, a night in a red coat and someone else I can't recognize. However that's not the important part, the girl is about to cut right through the red knight chest, but… something about this feels very wrong *throb**throb* this pressure in my chest, it's… like… I know that guy… like a really old friend… I can't let her kill him!

"Haste" I murmur again, I'm really tired but I have to do this.

I get there exactly in time, just before she slashes at him I put my keyblade between them and push her back.

"You may have helped my Master but I won't let you interfere" She declares in a scary tone

"I won't let you do this" I declare as well, taking my combat stance as the knight in red retreats.

Suddenly the blonde girl rushes at me and in less than a second is already in front of me, sword ready to cut my head off, I react in time but her blow is just too heavy for me to block with my wounded arm… she's going to cut me in half…

"Stop, SABER!" The red haired guy says just as our weapons collide lightly, I guess he also see this is plain madness. In any case she obeys the order and stops the attack.

"Shirou... Why do you stop me?" She says unlocking swords with me

"Because, he saved me, if he were an enemy he would have already killed me"

"…" the blonde says nothing

"Also if you're going to call me Master, then I would like an explanation" He demands an explanation from the girl, to which she only responds with silence again.

"––––So that's how it is, amateur Master-san?" The third figure appears from the shadows wearing a red coat.

"Thosaka... Rin..." The red head, Shirou, says astonished.

"So... You know me, good… that'll make things easier"

"..."he doesn't answer

"What's going on...?" I murmur as my sword disappears

"Archer... Go rest, Saber won't be easy until you're gone" she commands the man in red.

"Fine, but really..." he disappears like the man in blue did before him... And the swordswoman finally lowers her stance.

Silence fills the air for a few seconds before the girl in the red coat starts walking towards the Japanese house.

"Oi, Thosaka... Wait-"

"Hum, what is it Emiya-kun?"

"What are you doing?!"

"Isn't it obvious? I have a debt with you, so I will explain everything to you... Whether you want it or don't" she says calmly as she disappears through the porch.

Shirou seems to give up and enters the house alongside the blonde.

So... What should I do? Hum... Well, guess I'll follow them, who knows? Maybe I'll get some explanations this way.

A/N:

Well, yeah, his magic is also a bit upgraded but that's because Sora magic is well "magic" while the characters in Fate use "magecraft" they are completely different concepts, so yeah that's the reason why his magic is more powerful.

Anyway see you next chapter…
