Fate - Stay - Write - Go! [Fate/Stay Night AU/SI]

in that its near impossible for you to write more than 5 chapters of one thing before your muse rips you off to the next one?
No, that's my schtick. I've got a long string of half-completed stories as evidence. Cthulhu is the mad space tentacle monster thing, I believe, and one can summon it by calling it's name. Generally in a ritual.

Chapter One - AL - Caster
Chapter One

The temperature was mild as thin clouds of haze escaped my lips, my eyes accustomed to the low light as I flexed my fingers, my expression unwavering even as I felt the pressure within my magic circuits bud and grow.

"Lancer," I said flatly. "Do we really have to do this?"

Lancer smirked, "Come on! You should feel lucky this is merely a fight to test your skills."

"I'm Caster," I replied. "That's all you need to know, don't you?"

Lancer grimaced, "Just like that? I don't feel like leaving things hanging. How about you tell me your skills and noble phantasms and everything? While you're at it, give me your true name. Maybe then I'll leave you in peace."

I smiled softly. "I'm from the future, Lancer. I can easily give you my true name and it would change nothing. The name Kagayaku tells you nothing, does it?"

Lancer narrowed his eyes, "Even if that's true, I still need to fight to see your mettle."

"Lancer," I sighed. "I really don't want to fight you."

Lancer poised himself ready to strike. "A pity," Lancer remarked. "Because I want to!"

His body flexed and tensed, rushing forth with his lance aimed straight at me without a singular care in the world as it sliced through the air, whistling from the speed it reached. The crimson spear dug straight for my heart, wasting no movement at all as it passed all the way through, encountering little to no resistance.

My empty skin enveloped Lancer like a binding rope of tough as iron scales, the teeth-turned-fangs biting down upon his flesh like a hungry vampire seeking blood.

He easily ruptured through the empty skin, but I was no longer in the courtyard, and neither was Shiro.

I had jumped at the chance, giving Lancer the slip as I gripped with both of my hands Shiro's waist and hoisted her on my shoulder, before running away as fast as I could. I might have been Caster, but this still did not preclude me from being capable of running away very, very fast.

The first rule to being a good Magus was the same rule that applied to any situation involving zombies. Have good cardio.

Zelretch might have laughed it off, but I had been deadly serious in formulating the postulates for a successful Magus.

First rule of being a successful Magus was to have good cardio.

Second rule of being a successful Magus was to always have a plan, even when there was no plan involved.

The familiar streets I rushed through did not bring my mind down a trip through memory lance because the third rule of being a successful Magus involved the 'no daydreaming while executing a plan'. I did take in the roads I had traveled through, and the signs, and the familiar weight of Shiro on my back.

I remembered the bloody knee due to a fall and the pain in my shoulder in order to shield her from an explosion.

I remembered the laughter, the head-patting, and the coffee.

"What is going on!?" Shiro's exclamation was met with a snort from me.

"I'll explain quickly as we are short on time," I replied. "You have triggered the summoning circle within your shed after escaping from Lancer. I am servant Caster, and you are my Master for this Holy Grail War. The Holy Grail War is a war to the death between servants and masters, for the final purpose of achieving the Holy Grail, a wish-granting device that can make any wish come true as long as you are the last master standing. The problem is that it is a secret war, so eyewitnesses must be killed. The second problem is that it is easier to kill the master than to kill the servant. The third problem is that even if you remove your Command Seals, you can still technically make a contract with another Servant. So death is the only way out of this."

I spoke quickly, my feet carrying me past a few ground-level signs that hadn't been brought back inside yet. The moon shone over my dark hair as I took a shortcut through the streets, knowing them better than Lancer could ever be capable of.

This had been my 'hometown' for years. I knew it. Cu Chulainn was a hero of Ireland, and here in Japan his strength was vastly diminished. I was a Hero anywhere, but not of this time. How that worked was anyone's good guess.

Unfortunately, I didn't have time to guess.

Lancer wasn't renowned for being a 'blood hound' for nothing. He came upon us with his eyes wide from fury, his spear glinting with wicked magical energies.

"Did you truly think you could escape me, Caster!?" Lancer barked.

"That depends," I replied. "Am I really running away, Lancer?" I spun to face him, a tendril of scaly flesh escaping my right palm and striking at his face, only for him to easily swat it away with his lance -as long as he could see a projectile, he could dodge it.

"Sure seems like it, you coward!" Lancer's voice rose with the heat of anger, even as I merely took a turn into a tight alley once more.

Lancer did not take the bait, instead holding himself at the entrance to skewer me, but I rushed deeper inside, and he pursued. "A tight alley is best for a spear, didn't you know that!?" Lancer exclaimed.

"I know," I replied. "How else would I convince you to eat the bait?"

I grinned as my left hand tapped on the side of the wall, and the piece of skin that had been thrown prior broke through the wall from the side, teeth of iron formed once more to dig and pierce. Lancer spun to face the incoming threat, but the 'bullet of skin' was now the size of a rampaging boar, and as it pushed Lancer through the other wall, it brought him to a halt once more.

"And now we run once more," I said, "Well, I run and carry your heavy weight around-"

"Hey!" Shiro exclaimed. "You can't say that to a girl! You're rude!"

"I am merely being honest," I replied. "It is a rare and unfortunate occurrence."

Shiro grumbled as we made our way past the market district and towards the Ryuudou temple, where my footsteps climbed the stairs ten by ten, because I had no intention of being stopped before I could reach past the gate.

The gate that was closed.

Only with Assassin manning the gate do they keep them open at night?

Well, whatever, I didn't honestly care about that. I vaulted past them and landed on the other side, bringing my back against the wall as I took a deep breath to center myself. While I breathed, I shifted Shiro's position from being on my back to being in my arms, and for the first time, I stared straight into her eyes.

"I am Caster," I said trying to smile. "Your servant for this war," I added. "I hope we will be able to get along."

Shiro was breathless, probably from a combination of fatigue and the rush of adrenaline due to Lancer trying to kill her. "Did..." she said after a short while, "Did you kill that blue-haired madman?"

"I don't think so," I replied. "Miðgarðsormr's spawn isn't strong enough to hold down a Servant. He might have temporarily stopped him, but it was a matter of seconds, a minute at most."

I sighed, tapping my head against the wall. My back slithered with snakes that carefully began to burrow in the ground, intricately starting the nest of snakes that would be the foundation of the workshop, and that would allow the siphoning of energies from the leyline. There was no 'original' caster, which meant that if I acted fast enough, I could summon a 'fake'.

Now, if I summoned Nero as a 'fake Assassin', she'd kill me first out of anger, or outright be uncontrollable. Nero would never tolerate being unable to show her magnificence, and being an Assassin who dealt with poisons would be the end of her. No, it was better to 'tap this out' and deal with it personally.

Although three 'fake' Command Seals could give quite the boost.

If I was Caster, then it meant that Atriam Galiast was still alive and with a different servant. All I could hope for was that whichever other class it was, it would be appalled by the sacrifice of children and honorable enough to drive a sword through that particular master's guts before moving on to the afterlife.

Or I would be turning a particular building into cinder and ashes of course, once I began gathering magical energies from the Leyline rather than trying to make do with the pitiful amount Shiro could give me.

A jolt rushed through my spine as I instinctively clutched Shiro tighter. I had reached the leyline. The thrumming power of the Fuyuki leyline burst through the interwoven mystic code composed of the spawn of the snake that circled the world and burned brightly through the ritual's many glyph and numbers. The prana that flowed into my magic circuits filled me like a rush of adrenaline and second only to the might of the glorious coffee.

My teeth ground against one another as the hair in the back of my neck rose. The snakes began to further push out of my frame, their forms now thicker and stronger, the magical energies reinforcing them as they interwove even tighter, strengthening the area.

It was a nest of snakes. This, truly, was a nest of snakes.

The first servant that had to go would be Rider, if Rider was Medusa. She would be a terrifying opponent if she entered my Bounded Field.

Shiro closed her eyes sharply, taking a deep breath before opening them once more and exhaling in relief.

"The ground..." she whispered, "It looked like...snakes."

"Don't worry," I replied standing up as the ground shifted beneath my feet, calmly gliding me forward. "Within this Bounded Field, I am reasonably sure that nothing can harm you."

Shiro's eyes widened. "The monks!" she said suddenly, "What about the monks!? We can't stay here-"

"I'll talk with the chief monk," I replied, my right foot landing on the wooden floor just outside one of the temple's rooms. "This place is the safest place in the entirety of Fuyuki city with me standing in it."

"Uhm..." Shiro murmured, "I can walk."

"I know," I replied. "But I don't want to let you go just now," I added with a chuckle. Shiro's eyes widened as she stared at me with her mouth slightly agape. She then proceeded to ignore me, looking sideways and closing her mouth with a sharp 'click'.

Whistling, I found an empty room to leave Shiro in, and as a futon made of snakes formed -without her seeing it, or she'd never sleep in it- and her tucked in, I proceeded to walk through the temple that was slowly being 'engulfed' by the snakes, devoured and transformed to better suit my needs.

'There are too many motherfucking snakes on this motherfucking temple' was a thought that struck through my head as I found the room where the chief monk slept. I did say I would talk with the chief monk.

I never said I'd give him the chance to reply with his free will still intact.

I stepped inside and closed the door behind me, the sharp clack making the head monk snort as he woke up abruptly.

"Uh? Who goes th-"

"Apologies," I said, clutching the laurel wreath resting on my head, "But for the glory of Rome, your temple is henceforth conquered."

A single leaf of bay fell from the wreath, transforming into one of those Roman Aquila used as a Standard by the Roman legions.

The man's eyes widened, a murmur of 'I must still be sleeping' escaping his lips. The moment I pierced the floor with the Standard, the sound of the wood cracking near his head woke him up completely.

Unfortunately, it was too late.

A snake shot out from a nearby corner, and as the head monk kept his mouth agape in shock, it swiftly entered him. The man choked, clutching his throat. He then quietly wobbled on his feet, and stared at the Aquila.

"Iurant autem milites omnia se strenue facturos quae praeceperit imperator, numquam deserturos militiam nec mortem recusaturos pro Romana republica!" But the soldiers swear that they shall faithfully execute all that the Emperor commands, that they shall never desert the service, and that they shall not seek to avoid death for the Roman republic!

"Iuro." I swear.

"Now go back to sleep," I drawled, stepping out with the Aquila in my right hand as the head monk nodded to the empty room, before dropping back down to sleep like a log who had seen nothing, and heard nothing more.

I really should thank Nero for the gift the next time I saw her.

She made awful coffee, but when it came to gifts, an Emperor's favor was second to no one.

So we're dealing with the 'true' Kagayaku Emiya who became a Heroic spirit and not just Angry Manjew?

From what I've seen Angra Mainyu is more laid back and would just sit back and let things play out while he formulates a plan. Caster has already relocated, claimed territory, and suborned freedom of will by force feeding the head monk his snake. So I'd guess this is really Kageyaku!

Plus there's the whole assuming Sakura summoned Medusa as Rider, when the butterfly that is who got summoned instead of Caster has already flapped its wings. Angra Mainyu would wait and observe.

So since this is really Kagayaku I expect he'll kill Sakura fairly soon, in order to prevent Angra Mainyu from sending Shadows out to eat the town.
 
yeah, but in this route, angry manjew somehow managed to force himself into glitter-kun's place as a servant, and shiro earned her hate boner for shade, so... i expect this to end in tears.


who wants popcorn?
 
Yup, that's the real Kagayaku. For one, no fake can quite pull off his brand of crazy on the fly paradigm changes. For another, in the last route, Archer's memories specifically noted that her real brothers class is Caster.

Chapter Two - AL - Caster
Chapter Two

The fun fact was that through mystery and myth, what was ironically 'weak' in reality could turn out to be vastly overpowered in fiction -or in this 'reality that literally gave heroes powers based on how their fictional sides went'.

Thus, the older a Hero the more powerful he or she was, because the more time the legend of said hero had the time to 'consolidate' itself in the imagination of the people. So even if Nobunaga were to rise up in Japan, he would still meet a fierce opposition in someone like Genghis Khan, the renowned conqueror.

It was the main reason for Gilgamesh being so strong -barring his Ego and legend, of course. If only he wasn't such a troublesome opponent, then maybe I would have tried controlling him somehow. Kotomine Kirei could do it, and he was a rotten priest.

Still, I didn't want that. I wanted victory, overwhelming victory. No, more than 'wanted', I 'needed' overwhelming victory.

There could be no mercy given, and no quarters conceded. I needed seven Servants to die to reach the Root. I needed to reach the Root in order to-

A flash of light hurt my eyes slightly, even as I stopped straining my eyesight frantically looking for Lancer's potential assault. He had been called back, either because Kotomine hadn't dared to send him forward, or because he had done his due and had effectively lost me.

The flash was merely the rising sun, and the rays struck the walls of the temple, they shuddered for a brief instant as the warmth bathed upon the multitude of snakes and scales that formed the entirety of it.

To the mere common human, the Ryuudou temple was unchanged. To the trained eye of a Magus, there were a few differences. To my eyes, nothing but masses of slithering snakes composed the walls and the floors and, even if far more slowly than before, tiny 'offshoots' began to spread from the temple and into the mountain proper.

Whereas Caster had acquired the ability to teleport throughout Fuyuki city thanks to her magic abilities, I was more interested in turning the land into a 'domain' of mine. To fully utilize Nero's gift I needed conquest, blood, and a land to call 'mine'.

The day dawned and I jumped down from the top of the temple, my jacket fluttering in the wind as I landed on the ground, where the monks went about their business, not bothering nor caring in the slightest.

Caster had done the same to them in 'canon'. She had applied commands, and given them specific 'triggers'. It was one of the possible deaths of Issei after all, with her commanding him to stab his neck. I didn't plan on killing any of the monks, and the amount of energy I could earn from eating them was actually meaningless considering the vast amount rooted in the back of my mind.

The Leyline thrummed with power. I had no intention of 'burning' it up, but as long as the steady amount of energy that filled me remained in those quantities, I wouldn't have ever needed to do that.

Again, it was probable I would need to do that against Gilgamesh, or an 'unexpected complication'.

I was kidding no one. The leyline would burn, the city would burn, and I would need to rush to the finishing line with fire and flames and death encroaching behind me.

Souichirou Kuzuki was instead a pleasant surprise. He was not Caster's Master -of course- but a mere resident of the temple. He had felt something was wrong the night before, but had not been fast enough.

You can have the best breathing and walking possible, but if you cannot realize your first step lands you upon poisonous snakes, then you will not be granted a second step or a third to balance your act.

He, again, had similar triggers implanted on him.

I had no intention of letting a perfectly viable trump card capable of breaking Rider's neck from being consumed.

When Shiro woke up, I was there by her side, a breakfast tray by my side. "The head monk agreed to let us stay," I said as a matter of fact. "Should you wish to skip school today-"

"What time is it?" Shiro asked, her eyes deeply surrounded by rings due to her lack of sleep. A trumpet sounded seven quick horns, and as I nodded to the phantom sound, I replied in kind.

"Seven in the morning," I said.

"I...I need to think this over," Shiro acquiesced. "What happened-what is happening, everything else-I need time to think."

I nodded. "Breakfast?" I gestured at the tray next to me. "It's European cuisine, but you'll find me dead rather than eating rice or fish in the morning."

Shiro wrinkled her nose as she grabbed a piece of toast. "I prefer to cook my own breakfast," Shiro mumbled.

"I like coffee," I said plainly. "I spent most of my childhood being denied coffee because of an overbearing girl, and most of my adulthood being denied good coffee because of an extreme attention-seeking woman. Trust me on this," I took a sip of the cup in my right hand. "You do not know how good you have it, until you lose it."

I grimaced the next moment, shaking my head. "And apparently, roasted beans do not make for good coffee. I will need to restock."

Shiro bit down on the toast and took a sip of milk, before suddenly steeling herself. "I am Shiro Emiya."

"I am the servant Caster, my name is Kagayaku," I replied. "It does not mean 'Glitter', but 'Shining', 'Glowing' and 'Beam' if you really want to say it that way. Although normally, it should be 'Bright'."

I put the cup of roasted beans -who sane of his mind would roast beans- and began to nibble on a toast. "I told the head monk that there was an infestation of cockroaches in the house, and you were a friend of his younger brother. I am your father's brother from oversea," I added. "I came just in time to find out you were about to be shipped off with Yakuza, and I could not allow it."

I stared in the far off distance with a firm gaze. "My precious niece will not set foot in the house of local do-no-gooders!" I nodded to myself, a hand on my chest as I smiled triumphantly, "Truly, my masterpiece of acting. Why, my dear wife would be so impressed!"

No, no she wouldn't.

Shiro just stared. I grinned, "But you'll need your stuff if you wish to go to school. I took the liberty of sending a familiar to recover them," a snake slithered its way into the room, large enough to easily rival an anaconda. On his back he carried the clean clothes Shiro would need, as well as her school stuff.

"The bath is down the hallway to the left, Issei is having breakfast in the main hall. If you wish to head to school with him, be ready in less than twenty minutes," I stood up. "I will be following you to school, but worry not. I'll stick to the shadows." I crossed my arms in front of my chest as I walked outside, "Now be a dear and tidy yourself up," I winked at her, "You have a war to fight and victory to achieve. It's that or dying, and if you die...well, I'll never forgive you."

I closed the door behind me and sighed. Targets of opportunity abounded in the school, but only as long as the school remained open.

Rider had to be dealt with brutally and quickly, possibly by someone else.

I had a 'Saber' class to place. If it was not 'Saber' but another type of Saber, then maybe they'd cooperate with the children-sacrificing magus. Assassin was available for a very short time, and the sooner I got around to summoning him, the better.

Shiro would probably come up with hundred of questions to ask me when school was over, and I'd have to do my best to answer them, but for the moment, I had the morning free.

I stepped inside Copenhagen's shop and settled at a stool, grinning brightly as the owner of the pub and liquor store looked at me unsure for a moment, before walking over. "Can. I. Help. You?" she asked in English.

"Oh, don't worry and speak Japanese, I learned the tongue from my brother," I replied with a wave of the hand. Otoko Hotaruzuka was the 'big sis' archetype that gave a part-time job to little Shiro and the main reason Shiro had been unable to do archery. Admittedly, I used to work in this very same shop back when I was younger -although I was prohibited from 'tasting' the coffee, even after having dutifully bought it.

Otoko's father was the right sort of old man. The 'Master' of Copenhagen was a generous person, way more generous than normal.

When a kid asked for a cup of coffee, he did not refuse -once the bothersome females had left the premises, of course.

Otoko sighed in relief, "My English is a bit rusty," she smiled next, "What can I get you so early in the morning? We sell the finest liquors, but you can't drink them-"

"Coffee," I said. "My kingdom for a coffee," I chuckled. "Is your father in?" I asked as the woman turned, "I had something to discuss with him."

"My father?" Otoko remarked, turning and lifting an eyebrow. "He's in the back-are you a friend of his?"

I shook my head. "I'm Kiritsugu Emiya's brother," I replied. "I came by to thank the man for taking such good care of my niece."

"But you're not..."

"Adopted," I said with a small smile, "It runs in the family, adopting people. My father did it for me, and Kiritsugu did it for Shiro," I sighed. "If I had known he had passed away, I would have come earlier."

I bristled, tapping with my right hand on the wooden counter as I looked down at the grief-filled reflection. "Last letter I received was a few years ago-I simply thought it was how it went with letters. I live in Europe, so I reckoned a few might have gone missing or something."

"Oh," Otoko said. "My condolences," she said, her smile slightly bitter as she offered me the coffee.

"Thank you," I replied. "I'm making the rounds of everyone who helped rear up my niece. My next stop is a certain Miss Taiga. She's a professor if I'm not wrong-"

"Oh yes," Otoko nodded. "She teaches at Shiro's school. I'll give her a call if you want-"

I shook my head. "School's in session if I'm not wrong," I looked at the clock up against the wall. "I'll let Shiro give her a call in my stead," I took a sip of the coffee, and sighed. "Seriously though..."

"Yes?"

I stared at her with a firm glance. "What is up with the mix ratio of the coffee beans!?"

Otoko jumped back, her arms up in shock. "And the slight taste in the back of the espresso! You! How long has it been since you cleaned the inner components! No! Don't give me the frightened doe look, because it is inexcusable! Miss Hotaruzuka!" I stood up from my seat. "As a fellow colleague in the ancient art of bar ownership and coffee making, I cannot let this slide!"

"B-But we're a liquor store-"

"As long as you possess a coffee machine, then you are also a bar! And as long as you have a coffee machine, your duty is to make excellent coffee with it! There are no faulty machines, only faulty baristas!" I bared my teeth. "Change the mix-ratio! Adjust the water pressure-Clean the filters inside-"

"My, my, what is all this ruckus about?" the Master of Copenhagen stepped outside with a curious expression on his face, his mustache twitching lightly. "Otoko, what is going on?"

"I'm sowwy-nyan!" Otoko whimpered, "I'll make a better coffee!"

"No," I said with a sigh, pinching the bridge of my nose with my fingers. I opened my eyes the next instant, my gaze locking with both the owner and his daughter. "Look into my eyes and listen well."

They stared at me, their eyes growing heavier by the second as my whispered words came out as a gentle coaxing that they could not deny.

I stepped outside, leaving behind an empty coffee cup, the money for it, and hearing the last words of the master of the shop to his daughter.

"Let's go on a trip to Kyoto and close shop. Right now."

"Uh...I don't know why, but I agree dad. Let's go."

I smiled and pushed my hands further inside my jacket's pockets. The soft feeling of a picture touched my digits, and as I pulled out the photography taken years -decades, centuries- prior into that very shop, I couldn't help but chuckle at it.

I had my arm in a cast, and my expression yet was triumphant. Shiro's eyes were on the verge of bawling. Otoko was smiling and so was the master of Copenhagen. It had been taken after the 'accident' that would have normally resulted in Shiro dropping out of the archery club.

It was a photo filled with good memories.

It was because of that photo that I refused to let the city of Fuyuki burn with them in it.

My next stop wasn't the school.

It was a very familiar old style Japanese house.

"Bring me to Raiga Fujimura," I said firmly, my eyes locked with the guard that came to answer the ringing of the phone call in person. The guard opened the gate without a second word, and as I stepped inside, I dutifully followed behind her.

Taiga Fujimura had Ex rank luck -albeit maybe it was the creator trolling- and she was capable of avoiding meteorites striking the city by merely taking a walk. Raiga Fujimura did not have that luck.

He could use a vacation.

Him and all of his extended family of yakuza-members.

Maybe I could send him on a hunting trip in Africa, South America, or somewhere similar with everyone else.

Nobody would think any differently. He was, after all, famous for doing such things.

I pulled the photo taken at Copenhagen out one last time, and then extended my right hand to burn it into cinder and ashes. I blew the ashes away into the garden, and past it, to wherever the breeze of the wind would carry the remains.

"Master Raiga is having breakfast," the guard said, opening the door all the same.

"Uh? What is going on-"

I smiled. "Look me in the eyes...old man."

Truly, when I used Self-Hypnosis...

This all felt way easier to do.
