Prologue

"...Where am I?" I muttered to myself in disbelief as my eyes slowly opened and adjusted to the moderate rays of light coming from the azure sky. I could feel a small breeze blow past me and the sounds of rustling grass and insects as I awoke.

In front of me was a short young girl around my age wearing some kind of uniform, a black cloak with a white blouse underneath and a gray pleated skirt. She had reddish brown eyes, pristine white skin and strawberry blonde hair.

"Who are you?" Asked the girl as she examined my face intensely, casually ignoring the fact that my clothes was caked in blood and the many wounds that adorned my body.

"..." Going through the steps of kyudo I closed my eyes and took a deep breath before reopening them only to be graced with the same sight. I had hoped that it was my eyes playing tricks with me but I guess it was true that a green portal appeared out of nowhere and sucked me in right after I had saved Miyu.

"urgh" I heard a groan right beside me, a boy roughly my age was sprawled out on the grass. He had blue eyes, wheat coloured skin and black hair. He was dressed in a blue loose long sleeved jacket, with a raised collar over his short sleeve white t shirt, a pair of black jeans alongside with some blue and white sneakers.

"Hey I asked you a question commoner!" The girl said angrily as she waved her little stick in her hand, was that meant to be a threat?

"Trace on." All twenty seven magical circuits thrummed to life as they fed on my remaining Od, creating a small trickle of prana that coursed through my veins and nerves as I reinforced my body. I wasn't going to be taking any chances especially in my current condition.

Extending my reinforced senses outwards I noticed that I was completely surrounded by a group of young people, all of them wearing the same uniform as the girl and each holding some kind of stick within their hand. More importantly each person had an animal or phantasmal species by their side but compared to my own knowledge and experiences I couldn't feel any sort of power or mystery coming from them.

"Hey don't ignore me." My eyes darting from left to right as I surveyed my surroundings searching for the green portal that brought me here or a clue on my whereabouts.

"What's this Louise not only did you summon an injured commoner with 'summon servant' but you can't even make him answer a simple question?" A blond man asked in a mocking tone as everyone around him started to laugh.

On the horizon far off into the distance, was a huge stone castle ontop of a grassy plain. Judging from the workmanship and stone walls it doesn't resemble any castles I knew about, but I shouldn't come to a conclusion just yet I still need more information.

"Shut up I .. I just made a little mistake!" Louise snapped back in frustration at the taunts.

"Mistake? What are you talking about? Nothing unusual happened."

"Of course! After all, she's Louise the Zero!" A green haired boy shouted, and the crowd burst into laughter again.

"Um where am I and who are you guys? Waking up the boy beside me asked in confusion while shaking his head.

"Would you look at that, Louise the zero managed to summon another commoner as well! Truly you are on fire today my lady." The crowd started to laugh again while the boy just looked plain confused.

I could confirm my suspicions by performing a certain magecraft but this was neither the time nor place as I was surrounded by a group of people. Besides I'm not sure I could invoke it in my current condition as my body was a complete wreak from my battles with the Ainsworths.

"Mr. Colbert!" Louise shouted, clearly she had enough of this situation.

The crowd parted to reveal a middle-aged man. He carried a big wooden staff and was covered in a black robe.

"What is it that you want from me, Miss Vallière?"

"Please! Let me try the summoning one more time!"

Summoning... I see this was probably the reason why I appeared in this unknown place, she must have been the one behind that green portal. In that case her stick must be some kind of mystic code.

Mr. Colbert, the man wearing the black robe, shook his head. "I cannot allow that, Miss Vallière."

"Trace on." Taking a quick glance at her wand I went through the steps of tracing.

Judging the concept of creation. It's primary use is to act as a conduit and focus for the user's willpower so they could cast spells.

Hypothesizing the basic structure. A wand shaped to resemble a sword as the handle is thickened with a circular cross guard that has a tapered end. A unique type of lacquer was used giving it a matte black finish.

Duplicating the composition material. Black walnut wood was used for its construction.

Imitating the skill of its making. Created by Alistair a retired noble mage that specialises in the creation of wands and staffs.

Sympathizing with the experience of its growth. The wand is always been by Louise's side ever since it's was gifted to her.

Reproducing the accumulated years. It has been one year since it's creation, so far all the spells that Louise tried through the wand has backfired in one way or another creating an explosion instead. To date the amount of successful magic used with this wand could be counted on ones hand.

Excelling every manufacturing process. Louise's wand, it was gifted to her when the letter arrived with her successful enrolment to Tristain Academy of Magic.

"..." That was a mystic code? I expected something much more. It's only purpose is to act as a conduit for willpower and to focus said willpower?

So basically it acts as a pathway for the magical energy to actualise the mystery, so if they needed this the magi here doesn't have magic circuits making them extremely vulnerable once they lose their wand.

"Why not?"

"It is strictly forbidden. When you are promoted to a second year student, you must summon a familiar, which is what you just did."

"I see..." This confirmed my suspicions that I was in a different world, they were just too different from the magi I knew about not to mention all the other factors. To begin with summoning is a completely different category of magecraft than a familiar as the latter is created and seen as the symbol of the magus itself.

Not to mention the phantasmal species or animals by their side acting as mere familiars, to begin with it was near impossible to meet one let alone affect it with magecraft as they embody mystery itself but this.. it would be an grave insult to even compare the two.

"Your elemental speciality is decided by the familiar that you summon. It enables you to advance to the appropriate courses for that element. You cannot change the familiar once you have summoned it because the 'Springtime Familiar Summoning' is a sacred rite. Whether you like it or not, you have no choice but to take them."

"But... I've never heard of having a commoner as a familiar! or two in fact!"

Miyu... I had to find a way back to her or at least to my old world, as I couldn't let the Ainsworths continue their quest any further especially considering that there were methods to cross worlds but how?

The students surrounding Louise laughed. Louise scowled at them, but the laughter didn't stop rather they grew instead.

"This is a tradition, Miss Vallière. I cannot allow any exceptions." The middle-aged man pointed at me and the boy. "They may be commoners, but as long as they was summoned by you, they must be your familiars. Never in history has a human been summoned as a familiar let alone two, but the Springtime Familiar Summoning takes precedence over every rule. In other words, there is no other way around it, they must become your familiars."

For a summoning spell to work they require a catalyst or anchor on the other side and vast amounts of mana which I lack not to mention the magecraft itself.

"You have got to be joking..." Louise drooped her shoulders in disappointment.

"Well then, continue with the ceremony."

"With them?"

That being said for the summoning spell I could try to reverse engineer the spell that summoned me here in the first place and modify it to form a new magecraft, but that will take months if not years of research with my skills.

"Yes, with them. Hurry. The next class will begin any minute. How much more time is this summoning going to take? After mistake upon mistake, you have finally managed to summon something even if it is unusual. Hurry and form a contract." Everyone voiced their agreement and began jeering at the girl. While me and the boy just stood uncomfortably still in silence as this unfolded.

For the catalyst or anchor would my bond with Miyu suffice? Or would I need the coordinates for my home world instead.

Turning around to face me, Louise stared at my face as if she was troubled.

"..." I stared back at her in silence deep in thought.

"Hey," Louise addressed me.

"..." Then the problem was mana, how was I going to acquire enough mana for the ritual within a reasonable time span...

"You should count yourself lucky. Normally, you'd go your whole life without a noble doing this to you."

"..." I guess I have to integrate myself in this world for a time.

"Say something!" Louise let out a huge sigh as she resolved herself for what lies ahead. She was groaning softly as she mumbled to herself but to my reinforced ears I caught every word.

"To think that I the third daughter of the Vallière family... a noble who takes pride in her proper pedigree and ancient lineage, end up having to make a mute commoner my familiar. "

Louise closed her eyes with an air of resignation. She waved around the wooden wand in her hand.

"My name is Louise Françoise Le Blanc de La Vallière. Pentagon of the Five Elemental Powers; bless this humble being and make him my familiar."

She chanted those words over and over, like a magic spell, and touched my forehead with the wand. Her lips then slowly drew closer to seal the contract.

"..." I didn't know what she was doing but I could sense the magical energy coming from her and the wand which was used as a conduit. Judging from the context of things she was trying to create a magical contract with me, one with me as her familiar.

"Just stay still." Louise said, a touch of irritation in her voice as I moved back a step. Her face got closer.

"..." Although this was a viable method to integrate myself into this world I refuse to become someone's familiar. In that case I had to change the contract but how? Multitudes of methods flew past my head but were all quickly shot down, this wasn't the magecraft I knew about but their version. I took another step back to buy more time as I saw her face go closer.

"Ah, geez! I told you to stay still!" Louise was having none of this cat and mouse games, she grabbed my face roughly with her left hand. While I could have easily dodged it, I decided to let it go since I had already devised of a method to change the spell.

The moment Louise's lips touched mine, I flooded her with my prana forcibly trying to overwrite the spell with my own. In the end the best method was to use brute force and change the contract from the roots.

While the familiar contracting may seemed to have worked, it would in fact be a contract of equality, in exchange for obeying her commands she would be forced to pay something in equivalence for my services. With this I could use her as a springboard to learn more about this world and fulfil my goal.

A second has passed and Louise attempted to break off the kiss as she thought that would be enough to complete the spell. However I refused to let her lips part from mine. I haven't completed the overwriting, it was proving much more difficult than I anticipated as our magical energies was too different from one another, causing them to conflict but nevertheless I could tell it was working all I needed was a bit more time.

Moving forward I manoeuvred my tongue deep within her mouth as I attempted to emulate an adult's kiss in order to distract her. Her face was turning crimson in response to my actions as she attempted to protest before giving up. Taking the lead despite having no experience, my tongue clumsily intertwining with hers in slow motion as I attempted to stimulate her erogenous zones, our saliva mixing together during the process.

For a couple of seconds all was silent, the only sounds that could be heard was me making out with Louise as our kiss intensified. Overwriting complete, finally it was over I had completed my objective, now it was time to release the maiden and suffer the consequences. My lips parting from hers in slow motion as a thin line of saliva could be seen when we separated.

"..." Louise was in a daze, unable to release her womanly fury onto me as she was still shell-shocked from the experience.

I must have went too far with my actions, still if it was any consolation that was my first kiss and judging by her response it was hers too.

"Are you okay?" Feeling a bit guilty at my own actions, I asked her out of concern as she appeared to be blushing furiously with a blank look on her face.

Hearing me speak for the first time must have awakened her from the daze as she started to shout at me. "You You You How dare you that was my first." She didn't get to finish her sentence as Mr Colbert coughed loudly before pointing at the boy's direction.

""You may have failed 'Summon Servant' many times, but you have managed to succeed with 'Contract Servant' in one try." Colbert said happily as he witnessed a rare sight. It made him delighted as a teacher, to see a student improve no matter how slight.

"But you still have one more familiar to go Louise." Once more he pointed at the boy's direction as if to remind her she still had one more to do.

"... yes Mr Colbert." Louise said with a subdued voice as she tried to calm herself down.

"I am a noble of the Vallière family, it is beneath me to act so uncivilised." She mumbled to herself as if she was desperately trying to convince herself not to attack me.

Despite saying that Louise still looked in my direction with a look of vengeance in her eyes before turning them onto the boy. Letting out a small yelp the boy shivered for a moment as he received the full blast of her invisible wrath, before becoming completely still.

Once again she started the same process that she did with me, but this time she was far more careful in her actions. Clearly she was worried of a certain offence being repeated.

"..." I felt a sharp pain run through my right hand as if I was cut by a sharp knife. On the back of my hand was a strange symbol that slowly started to form into some sort of magical crest. The symbol was shaped in the form of a sword with a star shaped guard. "Argh." I felt another wave of pain when the strange symbol integrated itself with my magical circuits, and started to heat up giving me the sensation of being burnt alive.

My small cry of pain didn't go unnoticed as Mr Colbert approached me. "That was quick..." The middle aged magus mumbled to himself as he inspected the back of my right hand. "Hmmm.. This is very unusual indeed, normally runes would be inscribed onto the familiar but this seems to be a symbol instead."

A loud shriek of pain was heard from Louise and the boy, interrupting the magus from contemplating further about the weird marking on the back of my hand.

"Hmmm .. I should leave this matter for now." The magus turned his face upwards to face me, before he asked me a question." I beg your pardon but may I ask for your name?"

"... Shirou Emiya."

"Shirou it was nice meeting you. My name is Jean Colbert" He offered his right hand in a friendly gesture, one which I took with my own. After a firm handshake, the magus left towards Louise and the boy. No doubt he was going to check the boy for the runic inscriptions to see if the spell succeeded.

"..." Staring at my own mark, I felt a sinking feeling within my stomach as I thought about the way the magus acted upon seeing the symbol and my own knowledge of magecraft. Was this really the contract I created?

"Hey familiar come over here right now!" Louise was calling for me a couple of metres away with the boy who was currently kneeling on the grass. I guess answers would have to wait for now.

Author notes

Lazy bad author that only writes first drafts.

I decided to modify this story slightly in order to get back into the mood for this story. Personally I feel like Shirou has a real long road ahead of him if he wishes to make it back, as the world door magic used by Louise really only connects to Saito's world apparently.

Therefore it was luck that chucked Shirou here, lets see Enuma elish was used causing a rip in the world itself weakening the barriers between world, Miyu's own miracle activating to teleport between worlds, fanfiction powers, Louise world door etc. Truly an accidental summoning.

This is non serious story, due to the simple fact that Shirou could curb stomp the entire world if he so wanted too. I don't nerf characters, neither do I power them up without a valid reason, so judging from the feats of the zero verse I have concluded they are very weak in comparison to the nasuverse.
