Circuit network chapter 2

"This is your workshop Emiya-kun?" a clearly irritated black haired magus as she was lead by Shirou Emiya into the sanctuary where he practices the mystic arts, a forbidden area jealously horded by magi so that their thaumaturgal secrets would not fall into the hands of others, which was just the tool shed in the back of the estate where he keeps his tools for when he fixes Raiga Fujimura's bikes.

(10 hours ago)

It had been a few weeks since Shirou and Rin meet and a lot had happened during that time, from graduating middle school and passing the high school entrance exams, to picking the very same school that they both were going too.

After the entrance ceremony was finished they walked around campus after classes were over to try and see if there were any clubs that the two of them were interested in, at that point there were only two jobs that Shirou Emiya was interested in which consisted off the Archery club and Kendo club, however the Emiya soon found that most of the club members in the kendo club consisted of the very same members who were part of his old club back in middle school and the reason he knew this was because some of the members flinched at seeing him, obviously because the 'Torashinai incident' was still fresh in their mind, with that option out of the window the heir of Emiya decided to check out the Archery club.

The Archery club was in a dojo located by the campus side-entrance, it was a very nice building that had a traditional Japanese feel to it, deciding that he might as well take a look Shirou headed towards the entrance and opened the door to let himself in.

"Excuse me, I'm here for club tryouts is there anyone here that could help me?" he asked which got a reply coming from the centre of the archery dojo that sounded suspiciously familiar "oh more newbies, yes please come in we were just about to begin club tryouts" he then went inside to come face to face with the familiar image of a brown haired woman in yellow tiger striped clothes and overalls who was also surprised to her charge at the club she supervises.

"Fuji-nee?" Shirou asked as he recognized his sister figure and legal guardian which got a response in return as the childish adult "Shirou? What are you doing here? Wait don't tell me are you here for club tryouts?" Fuji nee asked as she didn't think Shirou was into this sort of thing.

This got a reply from the redhead as he said "Yeah I decided to try out a couple of clubs that I was interested in, and since my first choice didn't work out I decided to check this place out" after he said this an arrogant voice met his ears "well look what the cat dragged in, not here with Tohsaka today Emiya" he turned his head to the noise and found himself face to face with another familiar face.

"Shinji" he said neutrally at meeting his former blue-haired friend from middle school, it was a pretty strained relationship what with Shinji's prideful personality conflicting with Shirou's cheerful persona, however when the red-head started meeting Tohsaka more frequently ( in a purely professional manner), The Matou unfortunately saw it differently then what was really going on and seeing as he had feelings for the black haired teen had accused Shirou of stealing the girl from him by going out with her, the red head of course denied this but the blue-head wouldn't listen after that.

It was because of that event that Shirou was forced to end his friendship with the Matou on a sour note, of course Emiya being the kind hearted person that he was tried to patch things up but was shot down each time. And it seemed that the blue-haired idiot knew how to hold a grudge.

"I'm surprised that Tohsaka let you of the leash based on how much you seem to spend time with her, I didn't think you had any time for this sort of thing" Shinji said caused the red head to reply "I already told you ages ago Shinji that Tohsaka and I don't have that sort of relationship, speaking of relationships how's Sakura doing, your not still bullying her are you?"

Who he was talking about was Sakura Matou, the younger sister of Shinji Matou, during his friendship with the blue haired teen he was introduced to the plum haired girl by proxy and they got along well, although she seemed to have a habit of turning red often when he was around that he was worried that she had a cold.

"That's none of your business, and even if I told you I wouldn't let her near a womanizer like you" the blue haired teen said which almost got a retort when a voice broke the tension "Alright settle down you two we were just about to begin"

This came from Fujimura Taiga who saw the fighting between the two and wanted to break it up as soon as possible, not wanting to get in trouble Shinji decided it wasn't worth the trouble and lined up with the other 1st years in front of the 2nd and 3rd year students who introduced themselves and led them towards the changing rooms.

After changing into spare Archery uniforms the 3rd years went over the basics of Kyudo (Japanese Archery) while explaining the physical and spiritual aspects of the art, then the 1st years were told to line up and wait their turn before using the Archery range, when it was Shirou's turn he walked up to the podium and went through the 8 steps of Kyudo

Ashibumi, placing the footing on the wooden floor.

Dozukuri, forming the correct shooting stance.

Yugamae, readying the bow.

Uchiokoshi, raising the bow.

Hikiwake, drawing apart the arrow.

Kai, drawing the arrow across the bow to the fullest extent.

Hanare, releasing the arrow until it hit the bull's eye of the target.

Zanshin, Shirou remained in that state after firing the arrow until he grabbed another arrow from the pile next to him.

With another arrow in his hand he went over the Kyudo steps again getting another bulls eye, he had repeated the process until the black dot in the centre of the target paper was littered with arrows, he noticed that the bucket next to him that had the arrows was empty and asked one of the 3rd years "Sempai I've used up all my arrows, do I have to get more or is that all for today" the older student he addressed was to busy staring at him in shock much like the rest of the students in the club, before he coughed and said "No that's fine today Emiya-san go rest with the other ones who already tried" deciding to do what the 3rd year said Shirou walked over to a bench were some of the 1st years who already had a go were sitting.

It was pretty obvious that Shirou was a natural when it came to archery as he never missed the bulls eye once, this was because the philosophy of kyudo required you to empty out all unneeded thoughts and feelings and become one with the arrow, because the Emiya didn't have a sense of self to begin with it was easy to get that aspect down, plus the spiritual aspects of the art reminded him a bit of mage-craft so those two facts meant that the red-head was unnaturally good at Archery even though it was his first try.

As he found a free space on the bench in order to sit down he was found himself being addressed by a brown haired girl he recognized as one of the 1st years who showed promise in Archery "I got to say that that was some really impressive Archery there mr?"

"It's Emiya, Emiya Shirou, and you are?" he said back to the girl next to him who looked embarrassed " Oh sorry about that my name's Mitsuduri Ayako of class A, I just wanted to know how you managed to get a bulls-eye every time I mean I only managed to hit the target 3 out of 5 times"

"Oh its nothing amazing or anything, its just a feeling I had that's hard to put in words at the moment but I can tell you if I find the right words" Shirou said to the nosy girl before she went into deep thought before deciding to decline "No thanks, if its as difficult as you say then there's a possibility I won't understand it anyway, besides I happen to take pride in my skills so learning your tricks wouldn't be fair"

After the rest of the 1st years had their go the sempai's said that they had a really good batch this year and that everyone did really well but there were 3 that stood out from the rest.

The most talented was obviously Shirou as he had did the bullseye every single time, the second best was Ayako due to her hitting the target most of the time, the final one was Shinji Matou but didn't take it well due to being outshined by Shirou and Ayako. After that was over they dismissed the 1st years while they stayed to clean up as it was their first day and they handed each of them flyers containing club practice times.

After school was finished Shirou decided to keep his end of the agreement between him and Tohsaka by coming round Rin's house in the western residential area, he then started helping the heir of Tohsaka out with a few experiments that she wanted to try out, such as practicing her jewel-craft and mastering the spells locked in her crest.

When Shirou asked Rin about what jewel-craft does she explained the concept to him with her left arm around her waist and her right hand pointing upwards, this would later be known as the 'Tohsaka Rin lecture pose' she explained that Jewelcraft involved the flow and conversion of power in order to transfer prana from her circuits into the Jewels that she had been saving up, they would then be used for later uses such as powering strong spells, refilling her reserves, or using them as disposable magical grenades that explode with different kinds of force based on how much Prana was put into them.

She then went on about how different gems have different affects when prana is fed into them but their was something that bothered Shirou, he had heard about the concept of what was from his Dad but that was it and he also learned from him that the art was usually practiced by families with very large sources of income due to how expensive gems were.

He had explained as much to the black haired teen who forced to admit that because of her guardians incompetence in managing her families land, the only lands to her name was around the mansion they were in so she had to be careful when using magic gems as they were very expensive to replace, this had got Shirou thinking as he thought back to one of his earlier Reinforcement experiments, he had been reading about molecules in science class one day and found out when listening to the teachers lectures that gems were created when the volcanic and seismic activity in the earth would cause stones and rocks underground to have their molecules altered into different gems and metals over hundreds of years.

So with that idea in his head Shirou decided to try it out and went home after school finished and when he finished his part-time job, he then collected a few stones and rocks from the garden and took them to his workshop in order to try it out, he then picked up a steel knife and put it on a table where he found out the molecular structure of steel by using structural analysis, with that new info in hand he grabbed a stone from a pile he grabbed from the garden and started to use reinforcement to alter its molecular structure to match the molecules that were found in the steel knife, the end result was a shining grey lump of metal that appeared in front of him, he then grabbed it and analyzed it in order to decide if he succeeded or not, based on what he found it seemed that the rock was a lump of steel with a 75% purity which was not bad considering it was his first try, he then began experimenting on other metals like iron, copper, and zink, he didn't try gold or silver as it was a bit harder to create but after a few weeks or experimenting he succeeded, of course he made sure to store his results in a safe place as a emergency supply of funds as gold's value never changes no mater how much Japans economy changes.

When Shirou noticed Rin's shortage of gems due to her financial situation, he decided to surprise her rather then tell her outright so he could see the look on her face, his first step was to ask Rin for one of her rubies so that he could analyse it, of course the miser was reluctant to let one of her gems in another persons hand but after some careful persuasion from Shirou that he wanted to show her something she relented.

He then proceeded to analyze the ruby's molecular structure and after memorizing it in his head handed the jewel back to Rin, he then asked the magus to wait a bit while he went outside to grab some rocks from the Tohsaka family garden, when he came back he laid the pile on one of her tables and took one rock in his hand and decided to begin by using Reinforcement to alter the rock's molecular structure in order to match the ruby that the black haired magus gave him.

Needless to say the look on Rin's face when she saw a blood red ruby appear in Shirou's hand was priceless.

"How did you do that?" she said in awe as Shirou then proceeded to explain his theory on molecular manipulation in order to transform one rocks into different metals using reinforcement and thought that it would work the same with turning ordinary rocks into gems, normally Shirou was reluctant to share the results of his research with another magus, but decided it was worth it to see Rin walk up to the table and bang her head on the wooden surface calling herself stupid each time for being a supposed genius and not even thinking to use reinforcement to solve her Jewel shortage.

After calming down at almost giving herself a concussion, Tohsaka-san wanted to see if he could do it again and grabbed more of her families gems so that Emiya-kun could create more, after receiving more samples of Shirou's work which consisted of Rubies, Sapphires, Emeralds, topaz, Garnets and other types of gems the Emiya decided to make Rin a deal.

Shirou had offered to supply Rin with created jewels as well as 50% of the profits should she happen to sell any of them, in exchange of helping Shirou iron out the kinks of his molecular alteration, complete access to the Tohsaka library, as well as teach him jewel craft and any thaumaturgy styles that interest him.

After hearing Shirou's offer Rin weighed the pros and cons of this deal, on one hand this offer would help solve her jewel shortage and allow her to use her jewelcraft to its fullest extent. Plus if she played her cards right she could even buy back her families land and return her family's financial situation to normal with her share of the profits.

On the other-hand she would be letting an outsider read the accumulated knowledge that her family spent generations acquiring but she doubted Shirou was the type to abuse that knowledge or understand what half of books in her library contain anyway, it was a win/win situation for her either way.

With that in mind she came to a decision "Alright Emiya-kun you have a deal, but before we shake on it I need to see what kind of workshop you have if I'm going to teach you anything about thaumaturgy." This had pleased the Emiya as he was one step closer towards his dream, normally Shirou wasn't that interested in monetary issues but thought about how old his kitchen was and how limited it was for him to fully test out the extents of his cultinary abilities, with this deal he would be one step closer to finally having enough funds to fully renovate his kitchen into one rivaling a 5 star restaurant, after-all cooking was something he felt joy in doing aside from helping people out.

Which leads us back to the present day as Shirou brought Rin over to his house to show her to his shed where he practices his mage-craft, needless to say she wasn't impressed and was torn between laughing her ass off and using some explosive jems to destroy for being an insult to magical workshops everywhere.

"Is their something wrong Tohsaka?" Shirou innocently asked as the named magus glared at him "You're damn right something's wrong Emiya, where the hell are your magical tomes, your work station, the thaumaturgal catalysts, the results of your research"

At this set of questions Shirou was in deep thought before answering "well for the tomes I don't have any, Dad never owned any and he always taught me using practical methods, my work station is that wooden table over in the corner, I don't use any catalyst in my mage-craft so you won't find any here, and as for my research well their over on the floor but I'm not sure which things I reinforce and which I didn't, did that answer your question"

Rin was flabbergasted at the condition of the place where a magus like him is supposed to practice his art before sighing and rubbing her forehead "I give up, I guess I have my work cut out for me if I'm going to get this scrap yard of a workshop" Shirou was about to protest that his workshop was alright as it is but was stopped before he could "And don't you dare try to say this is alright, I'm honestly surprised you managed to get anything done in this scrapheap, in fact the first thing I'm going to do as part of our deal is turn this place into a proper workshop, trust me you'll thank me for it"

After that was taken care off Rin decided to examine Shirou's workshop in order to sort out which goes where when she almost tripped over something, she looked down to see a frying pan that was discarded on the floor, normally she would had dismissed it when she noticed something so odd that she was sure that she was seeing things, deciding to pick it up she took to take a closer look and froze at what she saw.

The metal pan was slightly transparent, as if it was made of glass, deciding that she needed more information performed structural analysis and almost dropped it in shock.

What she was holding was an object created using projection, an incomplete mystic art that uses prana to create a copy of another object, while it sounds convenient there are a few drawbacks that make it useless to modern magi, first the copies only last a few minutes and even then they are extremely fragile, second is that it not very efficient prana wise as it would be better to reinforce an existing object that has a power of 20, rather then project something that only has a power of 10.

However the thing that she was holding was not only stronger and more stable then projected objects that she was familiar with but that the pan she was holding was created Six months ago, deciding that she needed answers she turned towards the only person she knew who could have made this.

"Emiya-kun, can I talk to you for a minute?" Rin said seriously which got the boys attention as he walked towards her "Sure Tohsaka-san whats up?' he asked before she held the projected frying pan up so that the boy could have a closer look.

"Shirou, take a look at this and tell me truthfully, did you project this?" the hair of Tohsaka asked with determination in her eyes as Shirou was confused about why she was so serious but decided he might as well see what she was talking about "Isn't this just an old frying pan Tohsaka?" as soon as he said that he noticed something odd about the pan as it looked like it was transparent.

It was then that his brain decided to kick into high gear as he recognized what Rin was holding, it was when he was practicing his projection magic and had took a few supplies from the kitchen in order to practice with, he had picked a few up and started to go over the necessary steps in order make them, when it was complete he had near identical copies of the pots and pans he took from his cooking area but found that they were incomplete as they felt empty and hollow, he then decided to leave the copies in the shed as they would just dissolve in a few hours.

But what Rin was holding shouldn't even exist anymore as he had projected it over 6 months ago "Tohsaka, where did you find this?" he asked which earned him a reply "I found it over on the floor there when I accidently stepped on it, mind explaining to me what this as you clearly recognize it?"

Figuring he might as well tell her, as he was just as clueless as she was Shirou explained to her about his experiment with projection a few months back and how he gathered a few pots and pans from the kitchen, he then explained the seven steps he devised which include:

Judging the concept of creation

Hypothesizing the basic structure

Duplicating the composition material

Imitating the skill of its making

Sympathizing with the experience of its growth

Reproducing the accumulated years

Excelling every manufacturing process

After finishing explaining his method to her Rin looked like she was torn between throttling him for doing mage-craft wrong, or congratulating him for accidentally creating an entirely new branch of projection magic, but decided to think about that later as she needed to clear a few things with the red head.

"I am afraid that you're mistaken about how projecting works Emiya-kun, I know how it works and what you did here is definably not projection" this had confused the red head even more before Rin decided that she might as well explain it to him by adopting the 'lecture pose'

"Okay, first thing you need to know Emiya-kun is that the proper name for projection is Gradation Air, it is an incomplete art that shapes prana into a particular shape or form, its considered a useless art by most magi as the projected creations were very fragile and only lasted for a few minutes, the reason for this is because they are illusions of a real object so they end up being crushed by the world spirit GAIA"

"Take this for an example, if prana has the consistency of toffee, then projection mage-craft shapes that toffee into the shape desired by the sculpture, but no matter how sturdy the artist tries to make his creation it would eventually break apart as its still made of toffee, its because of this that magi only uses gradation air for creating disposable objects which are then used for complex rituals"

"But what you did is completely different as not only are the creations more complex allowing them to last around longer then normal projections, but they're almost identical to the real thing if you don't know where to look, meaning that your method has the potential to create an entirely new branch of mage-craft that has lots of potential in the field of thaumaturgy" she paused to let this sink into Shirou before thinking to herself, after all there was more to what Shirou did as he didn't even use any pre-existing materials to enhance the stability of his projection.

Magic is based on the principle of equivalent exchange and this holds true for gradation air as what you are basically doing is using pre-existing materials in your art, but what Shirou did was completely different as the materials used in the objects construction didn't exist anywhere else prior to his summons, what this meant to the black haired teen was unknown but she intended to find out.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx

After discovering Emiya-kun's unique talent for projection magic, which he decided to call Tracing named after his activation aria 'Trace on' the two magi got to work on testing the limitations of this accidental boon. After much experimentation Shirou discovered that he an easier job tracing bladed objects like knifes but could still do other objects with high chances of success, they also found that tracing only costs 10 units of prana no mater how big or complex the object as long as it had a blade.

Deciding to test out this theory the two of them decided to go to a museum in order for Shirou to have a good look at some of the weapons displayed there and try to see if some weapons were harder to trace then others (Shirou managed to convince Fuji-nee that he was going there for a history project, and he was interested in learning the history of his country).

The result was a beneficial boon as they found out two aspects about Shirou's new power, first was that the boy had a sort of selective photographic memory when it came to memorizing the information he gained from analyzing the different spears, glaives, halberds, maces, katanas, zeihandars, longswords, Chinese dao, and so on. The other fact they learned was not discovered until they came back from their trip, they had decided to use the Emiya estate yard to try out the latest editions they got to the museum by first projecting a katana that belonged to a samurai who served Hideyoshi Toyotomi during the Sengoku period of Japan but the results were more then they expected.

Shirou could not only project the weapons composition and the way it was forged, but could also trace its history as well and this enabled him to synchronize with the skills of its previous owner.

This ability combined with his selective photographic memory meant that if Shirou mastered Tracing he could one day become a very dangerous magus to fight, and that's not without even mentioning his ability to project hundreds of copies on the spot thanks to his insane amount of nerve circuits which rival powerful magus families with hairs possessing around 100 high quality circuits.

Though considering that Shirou was currently a 3rd rate, 1st generation magus with no magic crest, no sorcery trait or any research that was passed down to him from his family, and yet had accidentally managed to achieve two amazing feats that generations of magi would probably spend years to obtain was impressive in its own right. Plus his nerve circuits would only increase with time if his nightly routine to create a new one everyday were anything to go by.

After Shirou had gotten a full scope of his abilities and what they meant both to himself and to the magical community should he be found out, he made the decision to never join the Magus association or risk getting a sealing designation after Rin explained the concept to him.

Sealing Designations were 'achievements of the highest honor' handed out by the Mages Association to magi who managed to produce something through their research that was either forbidden by the Association or unique to the magus that could not be achieved by others through study, because of this the magus is deemed 'precious' by the clock tower and incarcerated and turned into a 'specimen' in order to preserve their flesh and blood.

In other words any magus who receives a sealing designation would be either sentenced to an lifetime of imprisonment in the clock-tower, or death so that their flesh would help advance the field of thaumaturgy leaving the sealed magus no choice but to become either a Philosopher who continues his/her research by any-means necessary, or a hermit who spends his time in isolation.

Fortunately Sealing Designations are only given out to members of the Association so he is safe as long as he doesn't join the organization, at worst he would probably be put under surveillance in order to study his abilities. After all having enforcers show up on his doorstep to try and capture him due to him being sealed would be hazardous to his grades.

Rin had put her hand over her face when he said this but she had gotten used to stuff like this by now.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx

The rest of the month went smoothly as Shirou was busy with School work, club practices, his part-time job at Copenhagen, and Rin trying to teach him mage-craft while he helped supply her with the necessary gems for her jewel-craft while she told him the correct composition that was needed for them to be used for jewelcraft.

"This isn't big enough!" "You call this a gem good enough to use magic on? Are you TRYING to kill me?" "I told you that I wanted an Emerald not a Topaz!" "Rubies ARE Sapphires you idiot!" "Do this over again! The cut is wrong! It will completely ruin the market value I mean the magical conductivity!" "Shirou! I need twelve pink diamonds by Thursday! Seven carrots each and not a milligram less!"

Needless to say thanks to Tohsaka Rin's instructions and guidance (read over-enthusiasm and greed) the boy got Very informative about the art of jewel-craft due to creating high-quality jewels and crystals, the training sessions he had also proved to him that the black haired teen was one of the scariest women he had ever met when she was passionate about something, and don't get him started on the evil laughter she makes from time to time.

On the days when Rin taught him magecraft she came to the unmistakable conclusion that Shirou Emiya possessed absolutely Zero talent for orthodox magecraft outside Projection and reinforcement, at first Rin was frustrated by this until she decided to try and find out Shirou's element in order to shed some light as to why he seemed to have trouble with normal thaumaturgy, what they found came as a surprise to the two as it turned ou the Emiya boys element was 'Sword' something that was obviously not of the standard 5 known by the association, when Shirou asked what Rin's element was she replied that it was 'Average one' giving her an affinity for every element known to man.

Not one to give up despite a set back the black haired magus scoured her library for a style of mage-craft that Shirou would be able to use of passable ability after-all no associate of her was going to remain a third-rate magus forever on her watch is she had anything to say about it, it was after searching through countless tomes that she came across a old book that was located WAY back in her families library that looked that it was a couple hundred years old, there was also a spell of preservation on it that prevented it from falling apart

It was an unorthodox style that originated from ancient Scandinavia during the age of the gods and had was also used in ancient Ireland by the famous hero Cu Chulainn, it required the caster to inscribe letters called Runes into particular, surfaces objects and even the air in order to enact particular mysteries based on the arrangement of the Runes inscribed.

Rune-craft comes in 4 different types, which consist of single-action Runes that only use one letter to enable a desired effect, Runic-chains that use multiple runes to enact mysteries on par with 3-5 count arias, Rune Words that use multiple runes to form words that create specific effects, and finally Runic names that use the runic alphabet to spell out the names of famous people, places or objects in order to perform magic or rituals associated with them.

Due to various reasons the art wasn't very popular in the Clocktower even though many notable magi use it, but for someone like Shirou who lacks talent in normal mage-craft it was perfect.

With that in mind She grabbed the book from the study in order to translate the foreign text into Japanese so that the two of them could read it, when Shirou found out what she was doing he offered to help out so the black haired teen shoved a Scandinavian dictionary in his hands and told him to start translating. By week 1 they had managed to convert more then a 5th of the book into Japanese that to Rin's immense surprise contained the entire extended Runic Alphebet, including the original 18 runes of Odin. When the black haired magus discovered this she was ecstatic that she had something that entire families would pay millions in currency to obtain, but curious as to why such a valuable tome was doing in the library of a family of magi that didn't even use Rune-craft in the first place.

Deciding that she might as well get some answers she searched though her families records written by past heads of the Tohsaka family and came across an entry from her great great grandmother Ren Tousaka, the daughter of one of the founders of the holy grail war Nagato Tohsaka.

Her Ancestor in particular wrote the entry during her participation in the Second Holy Grail war as the master of Lancer who was known in life as Gozen Tomoe, a female Samurai who lived during feudal era Japan, she had participated in the war when she was in her mid 70's though she still looked like she was still 40 thanks to her mage-craft enhancing her longevity.

The written account of her participation in the bloody conflict detailed her battle with other masters and their summoned servants but there was one in particular who stood out. The enemy in particular was a powerful foreign magus from Scandinavia who specialized in Rune-craft and had summoned a Rider who was a General from the Roman Empire, it was according to her ancestor one of the hardest battles she had ever faced as the magus used Rune-craft in a way that rivaled high-thaumaturgy but thanks to her use of Jewelcraft and Chinese kenpo she managed to hold her own, the battle lasted for a while until the two of them were nearly at their limits so the Scandinavian magus decided to end it by performing an A+ Runecraft spell called Tanngrisnir and Tanngnjóstr: Heavenly chariot of the Thundergod. This was an extremely powerful spell eclipsing all but the most powerful of Noble phantasms that uses 25 Runes in order to summon the personal chariot of the Norse thunder god Thor pulled by his two goats Tanngrisnir and Tanngnjóstr but could only be used if certain conditions are met.

After Reading this Rin paled at the thought of someone like that performing such a spell against her, it seemed that her ancestor shared her view as she rushed to kill the magus before he could complete the spell and allow his servant to use the chariot thanks to his Riding skill, fortunately thanks to the combined efforts of Ren Tohsaka, her servant Lancer, and the creative use of a command spell the two were able to kill the magus before he could complete the Runic-array leaving Rider to vanish at having his master vanquished and loosing his connection to the physical plane.

After searching the Scandinavian magus corpse for his ID and the location of his address and by proxy his workshop they raided the dead man's place of research until they came across the tome containing a handwritten book on Runecraft and a series of notes about the magus life, what they found was surprising to say the least.

It was discovered that the magi in question was the second born son of a family of magi spanning 3 generations that didn't possess a sorcery trait, in addition due to being the second born he wasn't given the family crest and had practically raised himself due to his parents spending time with his older brother more then him.

Wanting to prove himself to his family he had decided to perform an extremely dangerous Runic ritual in an isolated location when he was in his early twenties, the ritual in question was called Odin's Gallows a three-part ritual recreating the event of the norse gog Odin impaling himself on the world tree Yggdrasill with his Spear Gungnir given to him as a gift and sacrificing his right eye in order to aquire knowledge about the nine realms of the world tree.

This spell Requires three specific things in order for it to work, these consist of an Ash Tree from his homeland and standing in an area with high concentrations of mana like of a leyline (he managed this by buying Ash tree seeds and planting them in his houses back yard while using magecraft to accelerate its growth), a spear given to him by a friend or family member (he managed this by asking his brother for a spear for his birthday saying that he was fascinated with weaponry and wanted it mounted in his room) finally he needed to inscribe runes around his left eye and positioned so that the wound from the rune would seep into his eye rendering it blind.

The next step involved impaling himself with the spear and painting runic arrays on the spear and Ash tree (making sure that the location of the tree arrays are between two branches to act as gallows) tying a rope to the spear and finally hanging himself from the Ash tree for 9 days and nights in a state between life and death (he made sure that his family couldn't interfere in the ritual by saving up in order to send his parents on a 2 week vacation, and convincing his Brother to stay away from the ritual area so he could concentrate on his research)

Normally such a dangerous ritual would have killed an ordinary magus but thanks to a combination of luck and determination he had managed to survive transforming his elemental affinity to divine letters, his origin into Runes and gaining a sorcery trait called Rune god.

After being nursed back to health by his family he proceeded to use his new talents to master modern runes and became a magus that rivaled magi from powerful families with history going back hundreds of years, the handwritten journal located in his workshop was the culmination of his life's research in recreating Runic spells lost to the modern era.

Ren Tohsaka was so touched by the sheer risks the magus decided to take rather then rely on his families magecraft decided to bury his body in the foreigners graveyard rather then defile it in order to discover its mysteries while keeping the book so that she could guard it and keep anyone from abusing the knowledge it contained (due to not possessing a talent for rune craft she couldn't use the knowledge in the book anyway)

When she finished reading the last recorded moments of her ancestor's participation in the second heavens feel Rin had mixed thoughts about what to do next, it was obvious that the knowledge located in the Runecraft book contained powerful magecraft that would provide her with a very beneficial boon if she learned the Scandinavian art but that would mean sacrificing time she would normally use to master her families crest and other aspects of jewel craft.

Of course she decided to learn the rune-based style after the thought of her summoning a thunder gods chariot pulled by Devine beasts emitting lightning was too good to pass up, plus there was the fact that her grandfather was from Scandinavia fulfilling one of the conditions to use the spell.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx

After cramming another translation during their spare time the two magi managed to finally decipher Single Rune spells listed in the book as well as runic chains that use more then one Rune, there were simple spells like Eagle eyes that uses the Kenaz rune to enhance ones eyesight, to complex bounded field arrays like a housekeeping array that has to be placed over a leyline and the letters Mannaz, Ansuz, Dagaz, and Sowlio inscribed in order to produce a very hot flame that burns all matter of vermin and dust in the residence that the runes are inscribed in, destroying them at such a temperature that not even ash would remain. Rin decided then and there that learning this spell was one of the first things she would do as it would free up time to concentrate on her work which would normally be used cleaning the house as she lives alone in a big western style mansion.

There were also elemental spells for each element that would really be handy for her to learn due to her status as an average one but there were others that had various affects like memory alteration, and manipulating the human body in various way, often strange and hilarious like one spell that was used by female rune masters to change their cheating boyfriends/husbands into women, seeing as these types of spells were a little too advanced for the mages at the moment they decided to concentrate on learning single-action spells first.

By the time the end of May was over Rin had already mastered basic runes and had moved on to rune chains, preferably the ones focusing on elemental mastery due to her status as an average one, Shirou followed behind as he had successfully memorized the entire runic Alphabet off by heart (he achieved this by successfully reinforcing his brain, a very dangerous stunt to pull that earned him a whack on the head by Rin) but had trouble using arrays that focused on manipulating elements which was understandable due to his element being very specialized.

Though in a strange twist of fate Shirou was oddly skilled in using runes that focus on the healing arts, his favorite by far was the Rune of Resurrection, a powerful array on par with noble phantasms that uses the runes Sowilo, Kenaz Uruz, Tiwaz and Algiz placed either on the users body or clothes to heal the user to perfect health after suffering a mortal wound, in other words with this array Shirou doesn't Die when he is killed.

Naturally a rune this powerful has conditions for its use, the first is to act to succeed in the fulfillment of a duty given to him and must sacrifice themselves in the pursuit they were given, the second is obviously a large amount of prana inserted into the runes in order to use, the reason Shirou can use the rune is because promised his dying father that he would become a hero of justice that saves everyone and that he would gladly give his life in the pursuit of that dream if needed, naturally Shirou has yet to test it as no one he knows would ever give him a mortal wound in order to test out the rune.

His other favorite is the reinforcement array Self Improvement; a type of mage-craft used in training that creates physical and spiritual weights anchored to the person using the runes and improves the users magical abilities as well by clearing the mind of distractions and reinforcing his creativity and inspiration these facts make the array suited to both physical and magical training.

When he had read about this spell the heir of Emiya immediately spent much time in learning the spell so that he could use it for his daily training regimen when he wasn't practicing magecraft with Tohsaka such as his morning exersices, practicing archery, working various part time jobs, training with Fuji-nee in kendo, and finally creating another nerve circuit before going to bed.

Once he inscribed the array into his own body and turned them on he used them every day for one week in order to test out the affects, needless to say he wasn't disappointed, with that confirmed he used the runes everyday after he got up and before he went to bed in order to improve himself both physically and mentally, plus as a nice side effect his high-school grades improved, of course he made sure to turn the runes of for one day so that he could get used to feeling what his normal strength felt like and to rest his muscles from the strain they over went.

When he had told Rin about the spell she was reluctant at best but after seeing the results of his training in using the runes for two weeks decided to try them out, if only to use the mental enhancing aspect of the runes to improve her studies.

With that out the way Shirou continued with his mage craft training so that he was one step closer to achieving his dream of being a hero of justice and making his deceased father proud.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxx

"It seems that you've been improving your studies Rin, you actually managed to last longer during our spars" a man with priestly garbs in his late 30's said to the black haired Tohsaka who was breathing heavily after finishing her sparring session with her teacher and legal guardian Kotomine Kirei, "Can it you face priest, did you really have to hit me so hard I felt like my ribs were breaking" the said face priest merely smiled as he was enjoying his students clear annoyance "I wanted to make sure that you had a proper tolerance for pain as mage-craft is about walking with death , besides with your improved endurance and strength I had to try a bit harder to match your new abilities" .

Kirei was a member of the holy church and part of a secret sect of the Catholic Church known as the executioners, a group of religious zealots charged with hunting down creatures and rogue magi that threaten the safety of humanity and are violations of the teachings of god.

Normally a member of the catholic church would never be caught teaching a magus the ways of thaumaturgy or even have circuits to begin with, however he was blessed with circuits when he was born thanks to his late father's service to the church.

Plus was the fact that his father Risei Kotomine and Rin's father Tokiomi were friends and this friendship led to the man of god learning the ways of magecraft 13 years ago after Kirei's wife Claudia died, of course the real reason for his apprenticeship under Tokiomi was because he was chosen by the holy grail as a master in the 4th heavens feel and had participate under his fathers orders to aid the Tousaka's in obtaining the grail.

For that reason he started learning the mystic arts from the father of Rin in order to prepare him for the conflict and he proved that he was surprisingly talented in the field especially healing but for some reason always quit before achieving mastery in a specific field and merely moved on to the next one.

When the 4th war finally came he had summoned one of the Hassan of the Assassin class, more specifically the hundred faces Hassan who could split into a hundred copies of him in order for them to serve as a spy system for the Tousaka team to spy on the other masters, however this came to an end when he ordered Assassin to attack a meeting where Saber Archer and Rider were having a sort of feast but with only wine and no food, needless to say the servant was wiped out by Riders Ex ranked noble phantasm Ionioi Hetairoi: Army of the King that summoned Riders entire army from during his time as Alexander the Great.

Not far after that Tokiomi died in the conflict with his wife Aoi being admitted to a mental hospital where she died not long after, leaving the priest to look after Rin as both her teacher and legal guardian managing her estates until she was old enough to inherit them, though it was too bad he didn't do a good job managing them as the fell into the hands of outsiders soon after, he was a good teacher though.

"Still I am curious as to your sudden increase in ability in such a short amount of time, mind shedding some light on this my dear student" Kirei asked Rin who merely shrugged and replied "Oh its nothing miraculous I just came across an old tome in my families library that contained knowledge on Rune-craft, I decided to read it in my spare time and found some useful runes that enhanced my abilities, including one that serves as magical training weights"

Now this had surprised the executor, as he was unaware that the Tousaka residence had any books on rune-craft, heck he didn't think that even Tokiomi had any-books on that subject considering that his father was from Scandinavia to begin with, still he didn't expect Rin to actually learn an entirely new mage craft style then rely on her families jewelcraft guess 'accidentally' loosing the Tohsaka estates paid off afterall of her improvement was anything to go by.

"I see, well then I can honestly say that you've improved Rin but don't let your success go to your head just yet, you've still got a long way to go before you can match other magi in combat" this had surprised Rin as she didn't think there was much that would faze her as she not only has a steady supply of gems to use jewelcraft on thanks to Shirou, but she also had powerful Rune craft under her belt, making her a little bit confident in her abilities, afterall magi were researchers to begin with and not entirely suited to close combat, Kirei didn't count as he was an Executioner to begin with "yeah right, name 2 magi that would be able to match me in my current state and then I'll believe you"

"Oh I can think of a couple of magi that fits you're criteria, the first magi is someone I know from the apostle hunting missions I go on called Bazett Fraga Mcremitz"

"Bazett who?" Rin asked with a metaphysical question mark hovering above her head before Kirei continued "A first class Sealing designate Enforcer from Ireland that joined the magus association when she was in her teens and specializes in hunting down rogue magi and dead apostles, as far as combatants go she is what you call a 'magus killer'"

"As good as you think you are as far as Rune-craft goes, I am afraid that hers is superior as she inherited her knowledge of the Scandinavian art from her Family the Fraga's who have practicing the art for centuries, combine with the fact that she is older, stronger and more experience then you means that probably won't last very long if you happen to face her in combat"

This had cooled Rins ego down as Kirei informed her about the Irish magus based on his expert knowledge as an executor, so if he said that she wouldn't stand a chance in hell against someone and provided reasonable explanations as to why she would believe him, however there was something he said that she was curious about "hold on a seconds Kirei you said that there were two magi that would be able to defeat me easily, who's the other one"

At his charges question the 30 something year old smiled as if remembering a fond memory and replied "Emiya Kiritsugu"

As soon as Rin heard the name, especially Emiya she was hit was a sudden realization and thought "Emiya…Kiritsugu? Wasn't that the name of Shirou's father, no it couldn't be…. could it?" before asking her guardian for more info "em Kirei no offence but who is that?"

"I'm not surprised you haven't heard of him as his exploits were before you were born. The man known as Emiya Kiritsugu was a notorious freelancer known as the 'magus killer' that had managed to successfully kill every target he ever comes across and was often employed by the association to do its dirty work"

"Cold, efficient, ruthless, the man was the perfect killer who managed to successfully take out his target no matter the odds or methods used, however there was a side that many people didn't know about" he then adopted a cynical smile as he continued "it seemed that Emiya Kiritsugu wanted to save the world"

at first the black haired magus had doubts if the man Kirei was talking about was the same person that adopted Shirou, however the priests comment about the magus killer wanting to save the world sounded suspiciously like what Shirou told him about his father.

"A hero of justice? Are you serious Emiya-kun" Rin replied as Shirou decided to tell the heir of Tohsaka about his father on day after the black haired magus asked to know more about the person who trained him.

"Yeah that's right Rin the old man told me himself just before he died, he said that he wanted to be a hero who saved everyone when he was young but when I asked him why he quit he looked at me and said that he was unable to become one as when you save one like you would be unable to save another"

Shirou then looked at Rin seriously and continued "It was then that I made the promise to my dad that I would become a superhero and do what he was unable to do when he was alive which is why I was training for the past 2 ½ years since he died to become one in the first place, after all even heroes of justice have to start somewhere"

At first Rin was flabbergasted at the thought of a grown man having a childish dream like that and passing it on to their son, but after hearing Kirei explain the rest of Kiritsugu's motivation for what he did it all clicked together.

" Based on the testimonies of various eye witnesses that saw the magus killer act on every job he performed for the clock tower I came to this single conclusion, in every conflict Kiritsugu Emiya took part in he always managed to kill the target while making sure that the least amount of casualties were lost in the process, like he was weighing all lives equally no matter age, race or gender and tipped the scales so that the least amount of lives were lost, plus was the fact that he wasn't a normal magus either due to his use of modern weaponry"

He then closed his eyes and said "A foolish method for a foolish man, though despite his faults he was still a force to be reckoned with, so much in fact that I doubt even your father would have stood a chance against him if they were still alive" Rin was slightly outraged that Kirei's dismissal of her late fathers skill as a magus but she can ignore that for now as she had other things to worry about. "Kirei, could I ask you a question?'

This had raised the priest's eyebrows in slight surprise but decided to answer his stuent anyway "why yes Rin, what is it you want to know?" deciding that she might as well ask him Rin said, "Did the magus killer have any children?"

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxx

It was Friday night at the Emiya house hold and Shirou was sitting down with his guardian Fujimura Taiga who came round to mooch 'again' and was currently stuffing her face with Shirous excellent cooking before stopped eating and looked at her charge before saying "So Shirou, I heard some pretty suspicious rumors today about you at school today, you wouldn't happen to know anything about them would you?"

"A little, though to tell you the truth I don't really care about them as their obviously not true" Shirou replied back as he was munching on his food before Fuji-nee replied back "so you are not going out with miss Tohsaka even though you practically go round her house every-day?" the brown haired woman said looking at the red head with a suspicious look.

"For the thousandth time Fuji-nee we are not going out, I just help her out with some things from time to time since she lives alone, I swear there's nothing going on between us " he said repeating the same sentence he gave to every guy and girl at school who asked if he was going out with the most popular 1st year in school, he didn't mind at first but now it was getting really annoying, heck even Issei asked if I really had feelings for the devil as he calls her.

Ryuudou Issei was the son of the local Buddhist priest up at Ryuudou temple, they had met when Shirou often visited the temple to meditate on his spiritual centre and practice his breathing and walking exercises as part of his mage-craft training and they have been friends ever since.

The reason that Issei didn't like Tousaka was because they both served on the student council back in middle school but that that still didn't explain the open hostility he was giving the black haired girl, almost as if he could tell that her current personality was a mask and what she was really like underneath, but maybe he was thinking about it too much as it wasn't like Issei had any supernatural abilities or anything as that would be just stupid.

Still he was pretty surprised to hear the glasses wearing monk-in-training ask him if he was going out with Tohsaka as he didn't think Issei was the type to listen to rumors, of course he was relieved to hear that I had absolutely no feelings for Rin but left a friendly warning to be cautious around Tohsaka and left to perform his other duties.

"Alright I believe you Shirou, though to be honest I'm glad your spending time with someone your age instead of working or studying all the time" Taiga replied back as the go back to eating until it was time for her to go home, leaving Shirou to do the dishes and was about to go to the shed to practice his mage-craft until he heard the front door bell ring "wonder who that could be?' he thought as he walked to the front door and opened it, only to see Tousaka Rin standing there with a pained expression on her face.

"Tousaka-san? What are you doing here at this hour, do you need something?" the heir of Emiya said looking at the black haired teen waiting for her to reply before she took a deep breath.

"Shirou, we need to talk"

(30 minutes later)

It was half an hour later that Shirou sat on his cushion looking at Rin in silent shock at what he had just heard "Tohsaka, is this some sort of sick joke, what do you mean my father was some sort of 'magus killer' before he adopted me?"

This didn't surprise the teen who broke the news to Shirou as it would be hard to swallow for anyone "I'm not surprised you don't believe me Shirou but I swear on my family name that it's the truth, I heard about it from my legal guardian Kirei and he was an executor for the holy church so I can trust his sources"

With that the now christened 'son of the magus killer' slumped his shoulders in defeat and sighed heavily "you seem to be taking this rather well Emiya-kun, I would have thought you would be more upset, or shout angrily at me for ruining the image you have of your father"

"No its alright Tohsaka, I mean I hardly knew about what the old man did for a living before he adopted me so I had a feeling he did stuff that he obviously wasn't proud off if he didn't talk to me about it, but this…it's a lot to take in." Shirou said to Rin as she could understand the kind of feelings he was going through right now.

Besides she may have loved her previous teacher Tokiomi as both a role model and as a loving father, but the things he did while he was alive made Rin want to shot a gandr to his face, after-all what kind of father would willingly give up his youngest daughter to the Matous if he had at least some idea as to the kind of training she would go though under Matou Zouken's care.

It was the main reason why she didn't even talk to her sister Sakura not because of the agreement between her father and Zouken that the two would not even communicate with each-over (which she might add is considered void after Tokiomis death) but because she was to ashamed to face her after seemingly abandoning her and not acknowledging her existence despite being her sister.

It was then that her thoughts of her sister made her remember something else Kirei about the magus killer.

"Illyasviel von Einzbern?" Rin repeated in her head as it was not the name that she had expected to hear.

"Correct" Kirei said as he told the Tohsaka heir about the info he gathered using the churches information network "About 17 years ago Kiritsugu Emiya married into the Einzbern family a powerful magus family and one of the founders of the Holy Grail war by taking Irisviel von Einsbern as his wife, Illyasviel was born to the two of them not long after"

Rin processed the information in her head as to the significance of what it meant, the magus killer had married into one of the founding families of the heavens feel 9 years before the 4th grail war, she would bet her entire stock of gems that there was some connection between the two as there was no way it was a coincidence.

"I have a feeling that I know what you are thinking Tohsaka and I can confirm that you are right, it was no coincidence that Kiritsugu Emiya was accepted into the Einsbern's as they had hired him to represent them in the holy grail war 7 years ago." The priest said as Rin got her confirmation that she was right but that left one important question.

How was she going to break this to Shirou?

After going though the info that Kirei told her about the magus killer and his connection to the Einzbern family she decided to get it over with and break the news to the adopted son of Kiritsugu.

"Shirou, there's something else that you need to know about Kiritsugu" the heir of Emiya immediately paid attention as Rin only used his first name when she was serious about something, however what he heard next completely blew him away.

Rin then took a deep breath and said "Kiritsugu fathered a daughter when he was still alive called Illyasviel von Einzburn, in overwords she is your step-sister"

(To be continued)

Helloviewers Epicgamer484 here, first of all I would like to say that I decided to get rid of the opening at the top and instead talk about the chapter after you all have read it and had a look, though to be honest I am flattered at the 15 reviews I got for my first chapter, as it was more then what I got for the first chapter of Fate/Keybladeof wind but enough about that as I will now talk about the things I wrote about I this chapter.

The first things you would notice is Shirou noticing his tracing his tracing earlier in canon but don't expect him to start sprouting out noble phantasms as the grail war is not for another 2 years so he has plenty of time to iron out the kinks in his accidental miracle of thaumaturgy.

The second thing I put in is Shirou's ability to turn rocks and stones into gems, which I sort of 'borrowed' from Third Fang's excellent fan fiction From Fake Dreams which means that Rin now has a steady supply of gems to use but don't expect Shirou to be any good at it as he would mostly use Jewelcraft for storing the vast amounts of prana he makes for emergency's and other uses.

However the final piece is Rin and Shirou learning Runecraft, which is totally an original idea from me, the reason I had the black haired girl learn the Scandinavian art is due to a review I read about Rin being somewhat limited in her magical arsenal despite her being an average one, and runecraft has plenty of elemental spells so they would be useful for someone of Rin's skills, also I know that Shirou learns runecraft in Gabriel Blessing fic Inflight so I will get that out the way without someone reminding me in the review section.

Also the spells I listed in the fic were were all taken from a Rune craft index located on the forum website spacebattles, for more information you can see it for yourself by entering the address seen below into your web browser:

Well that's I have to say for now so please review and leave comments that would help me improve my fic, exept grammer as I don't have a beta but if anyone wants to be my Beta let me know as it would be really helpful of you.
