Author's note

I don't own Toaru majutsu no index, Fate/ Stay night or Heavens Failure. Maybe I do in some parallel universe out there, but definitely not in this one. Please don't sue me….

Hi there, sorry beforehand about the bad grammar, I am actually not that good with English. I wrote this fic in Thai first and then translated it into English myself, so it is very slow, the translation of this chapter alone took me two week. I wish my job was 5 days a week instead of 6 day a week, so I could have more free time, it probably will take me at least a month for each chapter at this rate.

This fic was inspired by EXpertUS's Intertwine (which was inspired by Dragon Raider's) and by Limit Break Circle's Fate/hollow ataraxia - Heavens Failure (Doujinshi). I love both and I'm somewhat sad that there is no new one coming out anymore, so I decided to make my own. Also base idea of Reality Marble = Personal Reality idea was taken from To Aru Fate Caren by Rinshi (Translated by Enlightened End).

For anyone who hasn't read Heavens Failure yet, in summary, it is an alternate end to the Heaven's feel route in which Shirou's body is dying at the end, but he was saved by Illya who combines his soul with her body, and we got Shirouko! one of the most MOE female protagonist in Fate series! Hurray! Sorry.. she's one of my most favorite character so I got a bit excited. XD

In the original Heavens Failure, Emilya's nickname sounds like Emy. But I think Emi sounds more Japanese, so I'll go with that.

Emi is probably a little OOC. I just thought that if a boy had to act as a (cute) girl for a year, her mentality would probably undergo some changes. Also this fic's Emi is a version after all Heavens Failure's volumes, has faced Avenger and Ruby already, though I haven't figure how Hollow/Ataraxia events will affect the story yet.

This fic is better enjoyed if you know fundamental elements of both Fate and Index beforehand. I will try to put in brief details of the basics for both series as much as possible, but don't expect me to cover them all.

This chapter alone, is beta read by the user 'AGreatReader' who helped looking over the grammar . Thanks a lot!

Though due to personal circumstances he won't be able to help with later chapters, so I still need a beta here!

Now, let's go on to the story

July 17 Tokiwadai middle school / present time

"Hi Everyone. Starting today, a transfer student from Germany will join our class. For those of you who wonder why there is a transfer student joining at this time of the year, since it is just only a few days before summer break begins, I will tell you that it is because we teachers want the new girl to have some more time to introduce herself and to get to know the other students before the start of her real lessons the next semester. Also we would like her to make some new friends that will able help her adapt to her new life here. Now, if everything is clear I' let the new girl come in and introduce herself. Come in Einzbern-san."

After the Homeroom teacher finished her speech, a small girl with pink hair reaching beyond her shoulder, dressed in a standard Tokiwadai middle school's uniform walked in and stopped in front of the class. She turned toward the other students and started introducing herself:

"Hello everyone, my name is Emilya von Einzbern, you may call me Emi if you like. While I am half-German, my father is Japanese, so I am quite fluent in Japan's language, please take care of me from now on." she said with a friendly smile on her face. There was a slowly raising murmur in the classroom as some students started talking between themselves about their new . There's no need to draw too much attention, I just need to portray myself as normal as possibl-

"Ah…! You are that girl from yesterday!" A somewhat familiar girl's voice echoed in the classroom. Emi turned her face toward the source and her red eyes widened because the speaker was the same famous brunette haired girl she had accidentally met yesterday, Misaka Mikoto, also known as Railgun, the 3RD strongest LV5 Esper of Academy city.

"W.. we meet again. Misaka-san" Emi stuttered, because last time the two met didn't end that well, and she had ran away from the scenes after that. But to meet again so soon, and find out they are to become classmates?

London, Clock-tower 2 days earlier

"…Do you seriously expect me to go to another dimension just because you asked me? Why should I do that!" the pink haired small girl in a white sundress, called 'Emi' by her friends, short for 'Emilya Von Einzbern', shouted in the face of the old man that sat in front of her, her red eyes glaring fiercely.

"Well, doesn't it sound interesting?" Kischur Zelretch Schweinorg, also known as Wizard Marshall, user of the 2nd TRUE magic 'Kaleidoscope', the old man of the jewels, the 4TH of the death apostle ancestors and 'the most annoying magus of the clocktower, who loved to play NASTY pranking', said with a tone like he was talking about the weather. "And mind your manners, a girl shouldn't shout like that, right Emi-chan?"

"I.. I'm sorry" she reluctantly replied. "But you know that despite my looks, I am.. I was a man before, it has not been a year yet since I got this body, so …please forgive me for my manners earlier." said the girl who once was a BOY named Emiya Shirou. She knew she had to please the man in front of her or else face any nasty prank that the old man could think of. Even the white sundress she was wearing now was a request of the man in front of her. He said that he wanted to see something that looked innocent once in a while. It was a bit annoying, but still much better than some of his nasty pranks though.

Almost a year earlier, the then teenaged boy, Emiya Shirou, a 3RD rate magus whose only wish was to be a Hero, had been forced to participate in a battle called "The 5th holy grail War" which took place in Fuyuki city every 60 years and whose winner would be granted a wish by the holy grail.

He also learned that this 'war' was the source of the great fire that took a lot of lives in Fuyuki city 10 years ago, a fire that had been the reason of his real parents' death and the start of his life with his adopted father Emiya Kiritsugu, the infamous 'Magus Killer'. After Kiritsugu death he inherited his dream of 'helping peoples' and the desire to be an 'ally of justice' which caused Shirou desire to win the holy grail and put an end to this war once and for all.

What he didn't expect, however, was that the supposed 'holy' grail was corrupted and would only grant wishes through destruction and the fact that Matou Sakura, his supposed 'innocent and pure' longtime junior in school and later his lover, had lived her whole life in a living hell since long before they knew each other because of reasons related to the grail war and that she had been trained to become a dangerous weapon that would complete the corrupt grail under control of the 'thing' that was her adopted grandfather, Matou Zouken.

After much struggle, many casualties, and after having rejected his own ideals in the process, Emiya Shirou managed to rescue his lover, destroy the corrupted grail and stop the war, but his body got injured in the process and was dying. Before he really died though, his soul was saved by Kiritsugu's daughter in blood, his adoptive sister, Illyasviel Von Einzbern, who gave him a new body to replace the damaged one, saving his life.

The problem was that his new body was his sister Illya's body, which due to various circumstances still looked like the one of an elementary schoolgirl despite her being older than him. Simply put, he… or better SHE now had become a little girl.

There were a lot of problems after that.

The first and probably less important problem was that she needed new identity for her new girl body, but that was quickly solved (no) thanks to Taiga, his honorary sister and grandaughter of the local yakuza boss. She was named 'Emilya Von Einzbern' against her will (by Rin), though she later came to accept that name since it was a combination of Emiya and Illya, so that it would always remind her of who she once was and of the one who gave this new life to her.

A much more serious problem was that the magus association now had an eye on her and on all her friends, due to the fact that each of the girls had their own unique valuable magic that most magi would kill to get and to study for themselves.

Matou Sakura, whose body had been in contact with the magic artifact called 'Holy Grail' for a short time.

Rider, a Heroic spirit summoned as Servant, now bonded as a very high class familiar by Sakura.

Tohsaka Rin, Sakura's sister, who managed to recreate the Jewel Sword, an artifact with the power of the 2ND TRUE Magic.

And Finally, Emilya, whose body had been modified by the 3RD true magic 'Heaven's Feel'.

All of this had drawn a lot of attentions from the magi of the Clock Tower, who would do anything to capture the three girls plus the ex-boy for their own research, a research that wouldn't probably be very pleasant for the specimens.

The magus association also wanted to punish Rin, who was the Second Owner of Fuyuki, but had failed to control the situation during the grail war.

Though, in Emi's opinion, no magus could be expected to control something like a war of SEVEN LEGENDARY HEROES fighting each other in a battle royale, with each of them strong enough to fight an entire army, without counting the fact that the supposed moderator of the war was taking part to the competition with an supposed to not exist eighth heroic spirit and had his own plan which if it had succeeded, would have resulted in the end of the world.

The four girls for a while were really thinking they would have to fight for their life again, this time against the magus association.

But all of their problems got solved easily by the arrival of the most famous Magician of the clock tower, the Wizard Marshall Zelretch, who, impressed with the fact that Rin managed to use a TRUE magic by herself, even if only an incomplete form, decided to take Rin as a pupil and also granted his protection to all of the girls that had interacted with the Grail war.

Not long after that, all of them had moved into the Clock Tower and become apprentices under Zelretch. Granted, even Zelretch himself had his own interest in the girls, but compared to the other magi that would no doubt do anything they could imagine to the girls for the sake of their research without any thought for the subject's wellbeing, Zelretch's method of research were much better. He only required a little cooperation and sometime they would get pranked by the old man for fun. Still, a few of the pranks the girls got from him sometime made Emi wonder if it had been really the right choice to become Zelretch's Apprentices in the first place.

Emi remembered about the one time that Zelretch managed to change all of their clothing into maid uniforms resulting in all of them having to dress as a maid for the whole day. For some reason, despite all four of them being together most of the time and even if everyone could see that Rider was the most attractive among them, she still felt as if everyone had their eyes on her the most. The fact that Sakura kept having nosebleed from time to time didn't make the situation any better. She also tried to make her call Sakura 'Master' for that day, and at night when the two of them had a chance to be alone in the room together…

No! Don't remember that! Emi forced herself back from that train of thought.

"Well, this time it isn't for my amusement alone". So he admitted that he did do this for his amusement, Emi thought. "In that world's Academy city… that's the name of the place I want you to go, there is a doctor who is known for his unmatched skill in healing. It is said that as long as a patient doesn't die before reaching him, he can cure them no matter their circumstances. I was thinking of having him take a look at that Matou girl's condition and in exchange you will have to live in that city for a while… What do you say Emi-chan?"

Emi froze after hearing that. A doctor who was so skilled that maybe he could cure Sakura's 'condition'...

Due to the VERY disgusting nature of the Matou family's specialized 'Crest Worm magecraft' that Sakura had been forced to learn, she had been the host for several of them. After the end of 5TH Grail war, they managed to get rid of the majority of the worms, but not all of them and some remained in crucial parts of Sakura's body and couldn't be taken out without crippling her. Even though their much reduced number meant they didn't pose a serious threat anymore, they were sometime still able to make Sakura… unstable, to say the least.

Yes, she and Rider (and sometime even Rin helped) knew how to cure that, but the most efficient method was that damn tantric ritual… well, Emi couldn't honestly say she didn't like that. Still, the fact that the symptoms could appear suddenly without sign at all was quite annoying.

One time it had happened just after Emi was involved in an event that drained her strength to the point that her body ached with the slightest movements, but both Rin and Rider were not available, and there was no way Emi would let anyone outside of her group do a tantric ritual with Sakura!

In the end, Emi had to withstand the pain while trying to do the tantric ritual to cure her lover. Emi felt like she had tasted what heaven and hell felt like at the same time for one night straight.

When she thought about that, her face started to become red again, YES, she had to cure Sakura's condition for real, for the sake of both Sakura and her sanity!

"Then… what do I have to do in this mission?" Emi asked, she may be only a third rate magus but she knew that before accepting any jobs from another magus, she needed to know the full details first.

"Well, to start with, in that dimension magecraft has developed in a different way than ours. Their 'magi' are called Espers and are categorized in Levels, from zero to five. Level 0 are the weakest while Level 5 are the strongest…Esper are peoples that have an ability that resembles Reality Marbles, but they are called Personal Realities instead. Come to think of it maybe some of them are more like Marble Phantasm... mmhh..." Zelretch looked like he was considering something.

In our world a Reality Marble, an ultimate magic that projected and materialized one's inner world onto reality, was considered a magecraft that came close to being a TRUE magic. It could be said that it was a magic that allowed the user to create an innate bounded field that followed the user logic rather than Gaia's, in other words it created for a limited time a world, separated from the normal world, in which the magus become a sort of god. It was a kind of magecraft considered as the taboo among taboos and the mystery among mysteries, it was one of the pinnacles for a magus, but research on this topic had been banned by the Mage's Association. Those that do have a Reality Marble, in fact, need to have an alien perspective of the world, need to be "distorted", and most magi that try to create a Reality Marble deliberately end up insane. For this reason and for its nature as a unique magical ability that cannot be acquired through study and does not pass on to one's descendants, the humans that do achieve this would inevitably earn a Sealing Designation if discovered. Obtaining a Reality Marble is not something every magus can achieve through research, it is a magic so inhuman that in this world's history, there are less than ten humans that managed to achieve it, and Emi was in fact the seventh.

"Anyway, all you would have to do is cooperate with a group of researchers there with which I have a contract. Those guys will send reports about Espers to you and I want you to sort through them and write me a research paper adding your own reports about Espers that you may met there. I will drop by to take reports from time to time. Oh… and you won't need to conceal most of your magic there., I did not stay there for long during my visit, but I witnessed a lot of interesting powers froma few Espers that didn't mind to display them in broad daylight. There was a girl that could produce and control thunder and another whose power reminded me of the 'BLUE' though hers was much weaker."

The name of 'BLUE', another Magician who specialize in destruction, made Emi's body shake slightly.

"Compared to something like that, your reinforcement and making something from thin air with your Tracing spell isn't that flashy, so you can use most of your magecraft ability in public there, because you can just say that it is a kind of Esper power. However, do try not to use Noble Phantasms or something that can be easily seen as magic. I also suggest you refrain from unnecessary killing anyone there, but that isn't your style anyway so I think that is all you need to know about this job."

Emi listened to all Zelretch said and understood the reason he became interested in this world a bit. A world where lots of peoples manage to achieve and then use openly their reality marble? That was really interesting, to think that there was a world where so many people were able to study that topic openly…

"Okay I understand that part…. then, when would I have to go and for how long would I have to stay there?" Emi asked. She had to explain to the other girls about this job first and prepare the necessary equipment.

To her (perhaps not) surprise, Zelretch just threw a bag at her. Quickly using Structural Grasping, she found out that inside of bag there was a lot of A4 size paper, a small card, like a credit card or an ID card and some other items. It looked like something you needed to live and identify yourself in another country and that thought gave Emi a really bad feeling.

An odd grin appeared on Zelretch's face, reinforcing Emi's suspicions and at the same time a crack appeared on the air behind her.

"Starting now and about for how long… I haven't decided that yet"

"…!" Before Emi could manage to yell, the crack on the air became some kind of portal, then a strong force came, sucking Emi's body inside.

"Trace on Enkidu!"

A long chain appeared in Emi's hand, one side of it went straight to Zelretch, but instead of hitting the old man, it went through his now translucent body. She still managed to make the chain change direction and used it to bind the desk in front of her, using it as an anchor to keep herself from getting sucked into the portal. Emi body was floating in the air, both her hands wrapped around the chain with all her strength.

If she hadn't been so busy, she may have recognized that the only things that were getting sucked into portal were herself and the bag the Old Man gave her.

"W… what the hell are you doing!?" Emi yelled to the only person in front of her.

"That's my line! How could you launch that chain to this weak old man? If I hadn't used my magic to transport part of my body to another dimension beforehand, I may have gotten hurt!" Zelretch's cheerful voice betrayed his words and told the truth about how much fun he was having at the moment.

What weak old man? Hell with that! She was pretty sure that even against something absurdly strong like Gilgamesh or ORT, Zelretch had a way to hold his own. He already pushed the whole moon back to the sky once for god's sake!

"Anyway, you don't have to worry about this side. I will take very good care of your girls during your absence. I'll even let them meet you there sometime… if you do your job well enough that is."

"Instead of all that, can't you just at least let me say goodbye to them first!"

"Well… NO. If I did that, I wouldn't get to see that desperate face of yours. Now Emi-chan, it's time to depart!" Zelretch's hand touched the chain that kept Emi from getting sucked into the portal. Instantly, Enkidu became transparent and Emi's hands couldn't touch it anymore. Her body got sucked into the portal behind her.

"Curse you, Zelretchhhhhhhhhhh!" That's last thing Emi managed to say before portal closed.

July 15 Academy City 2 days earlier

After getting sucked through the portal, Emi found herself in Academy city.

The Sun was setting and it had almost disappeared from the sky. After checking the bag that Zelretch gave to her, inside there were an ID-card, various credit cards, a pink folder phone (with the default background picture of Emi in a maid uniform, at least she knew how to change that.), notes about necessary things like the codes for the credit cards, instructions on what she need to do and on haw to find a place to stay.

Her cover story (made by Zelretch) apparently was that she was a transfer student from Germany who had recently discovered that she had a strong Esper power developed without using artificial methods (and Emi wondered the meaning of that. Artificial means?). She had to enroll in Tokiwadai middle school in the next 2 days, while living in the school's dormitory, spending some of her free time cooperating with skilled researchers who will analyze her ability in term of esper power.

Since she knew Zelretch well enough, she realized there was no chance she would be able to get back to her dimension until he was satisfied. With a sigh, she decided to just roll with what Zelretch wanted her to do for now.

After asking for directions (and after having found something to eat, one thing she was glad for was that at least Zelretch put a lot of money in her account, enough to live without working for a few years.) she reached Tokiwadai middle school's dormitory a few hours later. She was greeted there by the female dorm supervisor who had a strange threatening aura which reminded her of her Ex-Guardian Taiga Fujimura and after some complains about a little girl like her wandering alone at night, Emi gave the supervisor the necessary documents and was led to her room.

Her room was a big one meant for 2 people living together, but since there wasn't anyone to share her room with at the moment, she got to live alone and after brief explanation about the dorm's rules, the supervisor left Emi to rest in her new living space.

Emi felt exhausted (mentally) from what had happened and decided to take a bath and then rest. She had realized shortly after arriving that she didn't have any spare clothes or even basic equipment at all and that she couldn't just go out and buy things at the moment either because one of dorm rules was "All students must follow the curfew, and by extension, not leave the building after hours." which had already been over for a while. Sighing, she decided to just use a traced nightgown for the night, before buying anything necessary tomorrow. Thanks to all her training and due to Illya body's high grade magic circuits, she now could make mundane item last long enough if she pay attention during the tracing. After making sure that her traced-nightgown wasn't going to vanish before she woke up the day after, Emi finally rested.

July 16 Academy City 1 days earlier

Emi woke up early, changed into the white sundress she wore the day before (Because she still didn't have any spares yet, and while it was possible to just trace new clothes for now, she was still not comfortable enough about wearing only magically traced-clothes which could suddenly disappear, she needed at least some normal clothes to feel safe enough.) and since it was still a mostly free-times day for her, she decided to buy necessary things like clothes and then have some look around the Academy city.

Most magi were not very good with technology, but she was probably one of few exceptions among them (the others she knew about were Lord El-Melloi II who was a Japanese games addict and Zelretch who somehow was surprisingly good with it) thanks to her structural analysis. She was even capable of fixing some pretty advanced mechanism with the skill level of a real engineer which was quite a feat in itself, making her one of most knowledgeable person about technology in the whole Clocktower, though from a magus' perspective, it wasn't quite an achievement.

The technological level of Academy City though really awed her. Automatic cleaning machines could be seen almost everywhere in the city, the transportation system reached any part of the city easily and several other examples could be seen everywhere. Just looking at this place for one day made she knew how behind the times her world was, technologically speaking, at least.

Also what captured her attention the most, aside from all the technological marvels, was the varieties of foods in this city, it would probably take her at least a few months before she managed to steal all the recipes… ahem, taste all the foods in this city. That was just her self-imposed challenge though.

Emi spent most of the morning buy a few necessities, like casual clothes, student's uniforms, lingeries (She was glad to be able to select something more plain instead of something inappropriate like the things Rin and Sakura bought for her), cooking utensils (It is one of her most important tools afterall.) and other necessary items. After a few trip back and forth (and a change of clothes during that) she packed all she needed in her room then she left for the appointment that Zelretch made to evaluate her power in term of Esper abilities.

The place she was heading now would also be her main contact for the job that she got from Zelretch.

After reaching the Research Center, she was directed toward a test chamber to show her ability for the researchers to see. Emi started by tracing a simple kitchen knife (well, she is after all a sword and a cook, so the first thing in her mind was a kitchen knife.) in her hand, which they took to experiment on later and started questioning her about the specifics of her tracing.

"How many swords can you create at once?"

She traced ten different item around herself.

"Do you have any control on what you create?"

She traced another sword in the air and shot it to the target which conveniently was in the room with the speed of throwing a ball.

"Are there any requirements about the item you create?"

She explained that she had to have seen the item with her own eyes.

"How far from yourself can you create the item?"

She created another knife in the air 2 meters from herself.

The questions keep coming and Emi replied with 'half-truths' for most of them, she didn't want to show her full combat-abilities to someone she just met, so she only showed some of it. She was showing less than half of her real potential not counting her reinforcement and Reality Marble. Still, it was probably interesting enough for the researchers here cause they looked really excited about her power, she heard them say something like 'imagery', '11-Dimensions theory', 'Teleporter', 'Phychokinesis' and some other things that she didn't understand.

Finally they put her in a machine called 'Testament' which they explained was used to analyze a person's overall ability. During the analysis Emi found that her magic circuits were having some minor reaction with whatever Testament was doing to her, but since she didn't feel any adverse effect, she put it out of her mind.

After that the test ended and she was allowed to leave for the day, although due to some complication, the results would be sent to her later.

When she left the research center it was already late in the afternoon and most schools' classes had already ended for the day, judging from the many people in school uniform walking on the street and Emi decided to have a look around, find some place to eat dinner, before heading back to prepare for her first day in Tokiwadai's school.

During her walk, suddenly, her attention was attracted by a loud explosion.

While Emi was no longer a boy who wanted to be an ally of justice (both in mind and body, literally), at her core, she was still a person who lived to help people and, as soon as she heard the explosion, she reinforced herself and quickly ran to the source of the sound.

Once she reached the source, she saw a group of three men dressed with clothes that concealed their appearance walking out of the nearby bank's half destroyed entrance.

They were probably bank robbers trying to escape from the scene, however, there was another girl in their way.

The girl was a little taller than Emi, had brunette hair in a twin tails style and from her appearance Emi guessed she was probably a middle schooler, the fact that the girl wear clothes that looked just like the Tokiwadai middle school's uniform Emi just bought this morning reinforced her suspicions, the only difference was a green armband on the girl right arm.

The girl stood firmly with a confidence that made Emi imagine that maybe the girl was this dimension's version of Tohsaka Rin and she also looked like someone who knew how to fight.

Emi was proved right when one of the robbers, the biggest one tried to push away the girl by force, only to get his ass kicked. Another robber who seemed to be able to sense how dangerous the girl in front of them was, raised his hand and a ball of fire appeared.

Emi frowned looking at te scene. This was the first time she saw this dimension's magi with her eyes, and while the fireball was not that strong compared with many mysteries Emi had faced before, it was still lethal. She thought about interfering in the battle, but decided against it after seeing the brunette keep her cool and mock the fire-user.

A stream of fire released from the hand of the fire-user, straight to the girl who tried to dodge sideway, only for the fire to change direction to follow the girl, who then just… disappeared?

Emi blinked, she was proud of her reinforced eye, she knew she could follow Rider's (the fastest heroic spirit in the fifth grail war) movements, but she had missed the brunette's previous action.

Then in a blink of an eye, the girl appeared beside the fire-user and hit him with a kick.

'Don't tell me that girl mastered the second true magic Kaleidoscope well enough that she could teleport between dimensions at will!' Emi thought nervously. Her mind was put slightly at ease seeing that after the fire-user fell to the ground, the girl just brought out some sort of iron needles and used them to pin the man's clothes along with the wearer to the ground via her teleport ability, instead of using Kaleidoscope magic to trap the man in another dimension or to switch the fire-user's personality with the one of his harmless versions like the one where he's born as a sheltered girl who is raised to become the next head shrine's maiden, for example. Apparently it was one of Zelretch (not) funny ideas and one of his preferred methods to deal with bothersome people.

"Get away from me!" The last robber yelled, trying to flee from the scene. He pushed aside another short haired brunette middle schooler to escape, causing the Ice-cream in her hand to fall, dirtying her uniform in the process. The robber was trying to get into a car in a nearby parking lot. Emi almost moved to stop the robber from escaping...

"KUROKO!"

…But the angry shout from the short haired brunette stopped her in her tracks.

"S..Sir!" The second girl who Emi now knew as Kuroko replied back, clearly nervous.

"That guy picked on me first so… I can fight back, right?" The short haired girl said with a mono-toned voice. Emi felt in the air around her a strong electric power building up, a voice of Biri-Biri can be heard in the air, every one of Emi's instinct screamed to her that the short haired girl in front of her was DANGEROUS!

"U…Uh" said Kuroko already lost her word.

"I remember now!" the fire-user pinned to the ground shouted out of nowhere. "I heard about Judgement's evil teleporter who always humiliates her opponents in the cruelest way possible!"

"Did you just say something about me?" Kuroko said with a frown, Emi just felt that that description didn't fit the twin tailed girl at all… until she reminded herself that the girl somehow resembled Rin in a way… Emi just hoped that the girl didn't really have Rin's personality or that description would probably be right to a degree.

While his companion was speaking the last robber had already gotten in his car.

"Not only that!" the fire-user continued, ignoring Kuroko's protest "That evil teleporter already swore her loyalty to another esper, the one with the strongest Electro-type power in Academy city!"

Meanwhile the short haired girl brought out a simple metallic coin, as far as Emi's reinforced eyes could tell, it was similar to the token coins used in a game center.

Emi could feel the electricity in the air around the short hair girl becoming even stronger, the Biri-Biri voice was also louder.

"That's right." Kuroko said with a proud voice "That person is one on the top espers of this city, one of the only seven Level 5 espers in the 2.3 million people this place can provide, the 3RD strongest esper…"

The robber's car was running away and it was almost too far to stop. The short haired girl flipped the metal coin inthe air with her fingers, then, when the coin fell back to her hand…

A freaking laser beam-like attack shot straight to the ground beneath the running car, causing a giant explosion which threw the car in the sky a few meters high. It fell back to the ground, no longer functioning due to the impact while the driver was now knocked unconscious.

Emi didn't want to believe what she just saw, that girl just used some random metal coin to create an attack that was on par with a lower ranked Noble Phantasm, (could it be that she "broke" the coin and shot it?), and she didn't look tired in the slightest!

"…'Railgun' Misaka Mikoto onee-sama" Kuroko continued, "The proud Electric princess of our school"

"She is a monster." The fire-user and Emi said at the same time coincidentally.

Then suddenly Emi felt someone wrap his arm around her neck, making her breathing a little harder.

"You! You two monster over there! If you don't want this elementary school girl to get hurt, don't move or do anything!" the newcomer yelled, a knife held to her throat.

"B.. Big Bro! You have come to help us" the fire-user said, relieved.

Emi blinked, recognizing that due to her awe at the display of the two espers girls' power, she had become careless enough that she had been taken hostage by a man who was with those bank robber, either a scout or maybe the mastermind, and he just had to target her of all people around here…

Damn rank E luck.

"Don't hurt the girl!" Kuroko said in panic, it looked like her power wasn't as useful as Emi thought. It probably had an high cost or maybe there was some kind of condition to use it or else the twin-tailed girl would have already come to Emi's rescue. Emi could see that Kuroko priority was her safety, and it looked like Mikoto thought the same.

Emi sighed, she was the one that got careless enough to get caught in the first place, so she had to free herself. Also despite the fact she had accepted the fact that her height wasn't going to go change anytime soon because of her half-homunculus body, she still didn't like getting called 'little girl' or something like that!

"Trace on"

As soon as the aria ended, a steel sword shot down from the air, clashing with the knife in the hand of her captor. It was only a low-ranked mystic code but it was still far stronger than a mundane knife so a loud "Clang" could be heard when the knife shattered into pieces, while steel sword plunged deep in to the ground.

"What!" the hostage-taker said in panic, his right arm loosening.

"I'm not-" Emi said tracing another sword in a reverse grip position in her hands, this time a wooden sword filled with curses and a malicious intent. It had a tiger strap attached under the guard, it is a copy of a demonic sword that will not rest until it tastes blood, still sealed by the Fujimura family, the 'Tora-shinai'.

"-an elementary school girl!" Emi then thrust the wooden sword into the stomach of the man behind her. The man let her go and fell to the ground, holding his stomach in pain, Emi shook herself off the man's hold then turned back and put on a fighting stance.

"You damn loli!" The man was more resilient than Emi thought. He tryed to rise up and come for Emi, but he was stopped short-

"!" -Because now the Tora-shinai had unleashed its wrath, hitting the man between his legs, the most vulnerable part of any man. He released a wordless scream, foam forming in his mouth before his eye rolled back in his head.

"Big brooooooooo!" the fire-user screamed as if he shared the fallen man's pain (maybe he was?). Emi didn't care, even though she was once a man and knew how it hurt to get hit in that specific point, she wanted that guy to hurt as much as possible for daring to call her a loli, she hated that! Maybe she should hit him a few more t… NO! Tora-Shinai's bloodlust was getting to her because she was too angry, quickly Emi dissolved both weapons she traced.

"I am not a loli" she still holding a grudge for that.

"Are you all right?" Kuroko teleported to Emi's side and asked her with a concerned tone.

"I am all right. Thank you"

"Wow, that's awesome little girl, what kind of power is that?" asked Mikoto who was now standing beside Emi.

"I just create swords from thin air" Emi said in a sarcastic tone, answering the latter question first. Normally she wouldn't explain her power this easily but in this case Zelretch had already allowed her to disclose her power, it was not like she'd have to fight this two girl anyway, right? "And I'm not little girl. I'm already 15!" She said in an annoyed tone, that is what was on her fake resume anyway. Technically, her mind was probably 16-17 years old and her body probably around 20 years.

"What? You are this small but older than me!" Mikoto said in a real surprised tone, not really trying to look down on Emi.

However, it still made Emi get more annoyed.

Since she got this new body, it make her acquaintances worry about her much more than before, even after she re-trained herself in combat ability enough that she was even capable of fighting toe-to-toe against Rider (in the end she still lose though, Rider was just too quick for her now, but it still proved that she could handle most enemies on her own), they still mostly treat her like some little girl who needed protection. She didn't need protection, she wanted to be the one who protected! This has become her new bad habit in the last year, and it lead to her next mistake.

"I am older than you, and probably stronger than you, in case you want to know!"

Because she didn't know that what she just said would have a heavy consequences to follow.

Mikoto blinked a few times, then she grinned.

"Oh… Look like you are a confident one. LITTLE GIRL." Mikoto said, Emi didn't know yet that Mikoto was someone who was really serious about her power, electricity became dense in the air, Biri-Biri can be heard.

"Eh? …um I'm…" Emi paled after feeling the malicious intent originating from the girl in front of her. Even though Emi had become a girl for a year already, she still didn't understand a maiden's heart completely, she tried to apologize but not fast enough…

"Don't you dare look down on a Level 5!" A spear of lightning shot at the pink-haired girl to teach her a lesson, however, it got blocked by a pair of black and white swords that suddenly appeared in the girl's hands.

"Onee-sama! What are you doing… eh?" Kuroko seem more surprised about the swords that just appeared.

"Did you just tried to fry me Biri-Biri?" Emi yelled from behind the traced swords. Had she been a second slower she would have gotten shocked, lucky for her in that her instinct was fast enough and she managed to pull Kanshou and Bakuya from her reality marble to block the attack just in time. It also let her theorize that Mikoto's power at last, and probably the other espers' power, was indeed a prana based power and could be counted as magical in a way, otherwise the married swords magic resistance ability wouldn't have been able to protect her from that lightning blast, and she would have gotten shocked already.

Emi wasn't sure of what inspired her to call Mikoto with that nickname, but she soon understood it hadn't been one of her best ideas.

"And don't you dare call me Biri-Biri!" Mikoto was even angrier because Emi had unfortunately pushed another of her buttons, this time a stronger and faster lightning spear tried to move around to hit the target from an unprotected spot, but Emi managed to create a wall made of four floating swords between the lightning bolt and herself just in time without looking in the direction of the bolt at all.

Before Mikoto could manage to pull another attack however, someone grabbed her from behind.

"RUN!" Kuroko yelled, she didn't want to believe that she had to keep her Onee-sama from hurting someone like this, however she was a 'Judgement' and her job was to protect innocent people!

Emi decided to just withdraw from the scene and to head back to her dorm, she could hear Mikoto shouting something behind her while Kuroko tried to calm her down with a… lusty voice? Emi thought that it would be better if she tried to avoid Misaka Mikoto from now on.

"Those girls are monsters" An 'almost forgotten fire-user' told himself while looking at Kuroko who was using the circumstance to try to harass her Onee-sama. Which resulted in her getting shocked by Mikoto. "And they are strange ones at that" He concluded.

What peoples on the scenes didn't know was that the entire event had been recorded by security cameras around there, and that little show of Emi's skill would affect the report on her abilities once the researchers got to see it later in the day.

July 17 Tokiwadai middle school / back to present time

Emi feel the urge to blame her E ranked luck for what was happening now, there was no other possible reason aside from very bad luck that someone whom she had just decided yesterday to avoid at all cost became her classmate the very next day.

Well, maybe some higher power could arrange something like that, but who in the world would want a Faker and a Railgun to become classmates anyway? And why? For the lulz?

"Did you two know each other?" her homeroom teacher asked.

"…Yes" Emi quietly replied.

"We kind of coincidentally met yesterday, had a little talk, but she didn't give me her name" Mikoto said with smile on her face, a smile that to Emi, was somehow scarier than the angry face she showed yesterday. "Nice to meet you again Einzbern-san, I hope we will have some time to talk after this" she said and then she bowed as good manner dictated.

"Ah… please take care of me too, Misaka-san" Emi replied bowing back.

"Misaka-san is one of the top students of our school. She is a very good girl. If you ever need help, don't hesitate to ask her, Einzbern-san." The teacher said "On the other hand, Einzbern-san has been invited from Germany to study here because of her esper-ability is unique one, that is what I heard."

Actually she came from another dimension, that invite bit is probably what Zelretch prepared for her though.

"Eh… then what really is Einzbern-san's ability? I have seen a bit of it yesterday but I thought it was some kind of teleport ability that worked on swords, care to enlighten me? Also what is your power level?" Mikoto said trying to sound innocent, but failing to completely hide the mocking tone in her voice.

Instead of verbally sparring with the brunette, Emi decided that the best course of action was to use half-truths, explaining some of her abilities like she told those researchers the day before, so that in the long run, if she had to reveal more of her abilities, she could just say that she hadn't lied, she simply forgot to say some of it.

"My ability is called Tracing, I can create a copy of something I have seen like…" A copy of flower shape hairclip appear in her right hand. "…this hair clip of Misaka-san." Misaka brought her hand to her head to check that her hairclip was still there and found it. "But what I make is an inferior copy and will disappear after a while, the more complex and the greater the size of the item, the sooner it disappears, so I can't make money from selling my copies, unfortunately for me." She said sarcastically, getting some laughs. "And I can make the copy disappear anytime I want and I also have some little control over it" she let the traced hairclip float in the air for a moment before she let it disappear. "About my power's level, I'm not sure, those researchers said there was some complication during the testing so I don't know the results yet." At this a few voices started to raise in the room again to Emi's surprise.

Emi later found out that normally the results will be known right away after the test, her case was a really strange one, it wouldn't have been much help even if she had knew this beforehand though.

At that moment, another teacher come into the class and gave the homeroom teacher some document, telling her something, then quickly left.

The homeroom teacher gave a quick glance at the document then said "It looks like Einzbern-san's results have just arrived. Let's see…" then her eyes widened in shock, she froze then blinked a few times as if she thought she saw some kind of mistake. The class became silent upon seeing the usually cheerful teacher act so strangely, "It can't be…" she murmured.

"Is there a problem teacher?" Emi asked in a worried tone, she remembered that one of the conditions to enroll in Tokiwadai is that every student must have an esper-power at least level 3. She feared that maybe since her tracing was actually magecraft, not a true esper-ability, the evaluation system here may have estimated her as level 0. She hoped it wasn't so because it would bring her a lot of attention and a lot of questions on how she was able to use her power.

Her wish not to stand out for her low esper score was granted, just in an opposite way from what she want.

"Well… Einzbern-san, your power level is…" Teacher said slowly, turning the document toward Emi and letting see that printed on top of the paper alongside her picture in bold letters there was written:

Ability Name : Tracing
Power Level : 5

"You are level 5… the 8TH level 5 of this Academy city… Congratulation!" the teacher said with a low but excited voice, but since the room was mostly silent at the moment, everyone in the class could hear what she said.

"EHHHHHHHHHH!" Loud voices echo in the room.

Misaka Mikoto's eyes widened with surprise.

Emilya Von Einzbern knew then that her life in Academy City had just become even more complicated than it should be.

Damn rank E Luck

After note

I tried to write story on Emi's POV as much as possible, I wonder if it is good?

I also wanted to make Emi Level 0 initially instead of level 5 at first. But there really is Tokiwadai's rule about the minimum level for students, so I went this way instead.

My plan is to let Emi join in conflict of both Science and Magic side of Index-verse but not all of them, maybe more on the science side because I already let Emi enrolled in Tokiwadai and have a kind of rivalry against Mikoto.

I think I will follow canon up to the point of Level 6 shift/Sisters arc, while adding minor point to the story, after that I already planned some original arc, I will let Emi have a fight with Gilgamesh once for sure, I already have reasonable explanation for that, another is that I want to add Archerko (Sword dancer) in the story later, but can't think of any good excuse yet.

I also got some review that don't like that Emi got caught off guard during robber scene before rewrite, at first I plan to change that into something more awesome, like deflecting bullet that aim at Misaka, or some level upper user appear and cause some havoc, but after thinking for a while I still like the original one more, so sorry if anyone expect something new, and I want to portray that despite all she has been through, Emi is still a girl and can be caught off guard, she isn't that 'GAR' as archer yet.

ABILITY

Tracing : A

A type of projection magic that specialize in the creation of equipment while also recreating its history but with a lower quality. It also allows the user to record blueprints of various equipment in his/her mind if he/she understands enough of it. Due to changes in her body, swords have become slightly harder to trace, while other items have become easier.

Magic Resistance : D

Due to having a body with a very high prana capacity, Emi has developed a natural resistance against most magics. She can't be affected by magic with a power lower than D rank while higher ranked magic is reduced in power. This also protects her against esper powers that can be counted as elemental based and other magic properties with a power lower than D rank. Emi can turn off this resistance on purpose to receive effect of low level magic.

Clairvoyance : C

By reinforcing her eyes, this skill allows a clear vision at longer range, the ability to see high speed movements and also improve body movements by a little degree.

Magecraft : C

Emi has knowledge of Basic magecraft, her body actually possessed a natural gift for most magic but she doesn't realize that capability yet.

Soul of Steel : B

A special skill that raise her capability with sword type projection magic, reduce cost for sword and most sharp weapon type projection, due to the change of body that is now not fully compatible with her soul yet, the skill effect is reduced by one rank.

Eye of mind (True) : B

Capable of calm analysis in battle, even in danger, and deduce course of action, so long as winning chance is not 0%, this ability will greatly improve chance of winning.

Mystical Eyes of Binding : C

Ability to Bind/Hypnotize any person who looks into her eyes thanks to a sorcery trait that Illya's body possessed. Due to incompatibility with her soul, the skill effect is greatly reduced, it only works against unprepared targets.

EX-Einzbern's White Holy Grail: B

Emi's body has been modified to handle heroic spirits' prana, this gives a big boost to her body maximum prana capacity at the cost of wearing her physical body. The downside effect is always countered by Avalon though.

Dress of heaven (Remains) : D

The remains of the dress of heaven that Illya used to save Emilya's life is now combined within her body. While not capable to achieve TRUE magic anymore, this skill help raise Emilya's skill in tracing clothes equipment slightly.

Avalon : B

A hallow scabbard of Excalibur that dwelled within her soul, granting high level of regeneration from damage, it also keeps her body in a good condition even without any treatment. Due to not being the true wielder (Arturia), the skill rank is reduced.

Cooking : B+ (Originally A)

Theoretically Emican cook a meal better than most 5stars hotel chef, but her smaller body has maee her a little clumsier in thekitchen, reducing her skill by half a rank.

Target of a certain kind of attention : A

Having the body of a little girl (and a cute one at that) draws a lot of unwanted attention. At A rank a certain kind of people will want an interaction at first sight.

Weakness against modern technology : E

Having a magus mindset that ignore/can't understand modern technology, but at very low rank it only reduce her interest in modern technology by certain amount. She is still able to learn about modern technology even if it is slightly harder than normal for her. most magi have this skill as C rank or higher. At EX rank, a magus would be able to destroy any high-tech item in the span of a few minutes accidentally, regardless of how sturdy it is.

Noble Phantasm

Avalon : The everdistant Utopia : EX

The hollow scabbard of Excalibur, when its true power is activated, the user will be protected by an absolute defense that completely shields the user in the domain of the fairies, isolating the user in a world that is separate from the regular world, at a cost of a constant high prana drain.

Battle Dress : D

A very well made original design overcoat that she can recreate with tracing, it is embedded with runes in certain parts to grant better resistance to the material and to reinforce the wearer's power by a little margin. It can be reinforced with magic much better than normal clothes and Emilya can create multiple spares to give to her allies. Just like any traced object the clothes disappear after a time. The design resembles Counter Guardian EMIYA's armor. The original Battle dress is a defensive mystic code comparable to a C ranked noble phantasm created by Emi with help from her magus friends (Rin,Bazett and surprisingly, Caster).

Unlimited Blade Works : E-A++

Unlimited Blade Works is a reality marble that represents Emilya's inner world. She unlocked the ability to project her Reality Marble on the world after the Grail war with Zelretch's help and data from Archer's arm. When this ability is activated the Reality Marble will replace the world around the user and will bring the designed target into her own world. In this world there is an endless hill of swords, the sky is the colour of twilight and Sakura petals fall from the sky. While inside this world, Emilya doesn't need prana to trace swords or bladed weapons and the cost of other items is greatly reduced, however prana is still required to activate certain items active abilities or to "break" a noble phantasm. She also can't create something made of a material that is unknown to this world. To manifest and to mantain this reality, high amounts of prana are needed, even with Emi's body very high prana capacity, she can only hold Unlimited Blade Works for a few minutes at the most.

Though she has unlocked it, her reality marble is not yet perfect since her perspective is too different from the one of the heroic spirit EMIYA. Currently, the amount of weapons she can create/control at a time is limited even with Unlimited Blade Works active, for now she can control roughly 100 item at the same time. Also for some reason, if the real Matou Sakura is present in this world, all weapons will be upgraded by one rank though they still will not surpass the original.
