Chapter 1: Electromasters, Railguns And Lucky Strikes

With my eyes drooping, I thought better than to click "Next episode" and instead decided to sleep. The red LED's of the clock next to me informing me of the early hour. I switched off the third episode of "A certain scientific railgun" just as the credits began to roll. I dropped the remote next to me as the tv turned dark. My eyes drooped and finally closed, sending me into what I assumed to be a dream at first.

When my eyes opened once again, the darkness of my room had been replaced with the grime covered floor of an alleyway.

"Wait a second, this isn't my apartment..." I thought to myself.

"Hey!" I heard familiar female voice call to me. "You gotta focus!"

"Wait, hold on...that voice...it couldn't be..." I thought to myself, as I looked up to see Mikoto Misaka staring at me with wild eyes. "Sis, we got a situation here! I don't need you zoning out, girl!" Misaka said, as she gestured frantically at the thugs surrounding us.

"Wait, Britney Karbowski?" I asked myself, as I recognized the voice actor behind the girl.

"Wait, did she just call me girl?" I thought to myself, realizing what she had just said to me.

As I very much knew myself to be a guy, I looked down slowly as my hands came up slowly, my hands resting on the foreign lumps on my chest at the same time as my eyes.

"Well, this is going to take some getting used to, I guess I'm a female now," I admitted to myself silently.

It was then I noticed a single tendril of soft blue hair had fallen into my line of sight. My brows furrowed at the color, knowing my own hair to be short and dark.

"Okay, so my natural hair color is light blue? I guess that is something else to get used to," I thought to myself as my eyes scanned the rest of me.

"School uniform?" I thought to myself as I sighed, school was the one thing from my childhood I had never missed. I then looked up at Misaka once more and noticed our uniforms to be the same. The Tokiwidai middle school emblem embroidered in the corner.

"Earth to my sister?!" came Misaka's voice, as she pulled me from my stupor and back to the fight.

"Okay, so I guess I am in the world of the A Certain Scientific Railgun anime...I only managed to watch as far in as the dummy check episode...still...I may not know anything past that point, but I do know of Mikoto Misaka...so this is what the 3rd ranked level 5 Esper in all of Academy City looks like in person...not to mention that she holds the nicknames of both Railgun, and The ace of Tokiwidai...Wait isn't she supposed to be a tsundere with a very short fuse? Well then...let me just make a mental note of that being part of who she is...because I am going to have to learn to get used to that...hold on...wouldn't me being her sister technically mean that I am an electromaster as well? I can't assess that, at least, not in this alley...still...I might as well help her out since I am here...okay let me concentrate..." I thought to myself, as I then took a breath and calmed my mind. "Okay...concentrate...oh...well that is an unusual sensation..." I thought to myself, as I then felt electricity course through the air before it seemed to course through me. And after a moment, the gathered static shot down my arm and out through my fingers, leaving goosebumps on my skin at the sudden new feeling.

The alleyway then lit up with a flash as all the thugs shuddered erratically, their bodies unable to cope with the force of my attack. Once the lightning had dispersed once again, the alleyway fell dim, the light of the shocked men vanishing almost as soon as it appeared. They made only dull thuds as they dropped to the ground one by one until it was just me and the girl who called me sister in the alleyway.

I then looked at Misaka. "Wait, I did this? That is clearly the case, seeing as how Misaka hadn't attacked at all..and what is this smell in the air, it's as if someone has toasted a piece of bread on the highest setting, because this alleyway is filled with the stench of burning. Well, that is going to leave a memory I can never erase." And as he seconds ticked by, stench continued to linger. I then crinkled my nose and sighed. "I really hope I don't have to get used to that smell...because that is quite a strong odor..." I thought to myself.

It was then that the sound of shoes hitting the sidewalk, caused us to stand defensively once more. That is until a familiar face coming around the corner made Misaka ease. I, however, stood my ground as my blood ran cold. "Oh right I forgot about her..." I thought to myself. As Kuroko Shirai then began her judgment introduction. "Halt! In the name of judgement!" She demanded, her breath ragged from her desire to get to the scene faster. "We have been alerted to your activities, come quietly or I will be forced to-" She stopped mid sentence at the sight of us and the various scattered bodies in the alley. She visibly smelt the charred remains of the thugs as her nose crinkled. "What happened here?" She gasped, trying not to inhale too much of the smoke emanating from the deceased thugs.

"Oh, hey Kuroko," Misaka said, giving a polite expression, as electricity crackled through the bangs of her hair.

"I guess Misaka's polite personality is accurate to the show..." I thought to myself.

"Sissy…and Keiko, you're here too." I then resisted the urge to turn and shrug, instead choosing to raise my hand and smile awkwardly.

"Keiko," I repeated to myself. "Add my name to the list of things that I need to get used to," I thought to myself, as I inwardly sighed.

I then watched Kuroko's eyes drift down to the Misaka's chest and then back swiftly, thinking no one saw her quick glance.

"Oh, well I see that Kuroko is still a pervert like in the show...and I thought that Infinite Stratos's Tabane Shinonono was perverted, actually you know what...let me do my best not to make an enemy out of her...she is Misaka's...well...let's just gloss over the fact that she calls Misaka 'Onee-Sama' , or 'sissy', since this is the english dubbed version of the anime...well...time for me to make light of the situation..." I thought to myself.

"You still don't skip a beat when it comes to being a judgement officer, eh Kuroko? You'll be appointed a superior next," I sassed with a toothy grin. Unexpectedly, Misaka giggled at Kuroko's now pink cheeks, and yet, Kuroko wound up giving a small shy smile at the thought. And silently, the three of us then thought it best to avoid giving an explanation of the scene.

Instead, choosing to return to school using the park as a shortcut. Misaka kicked a vending machine as we all stopped to huddle around it and choose our drinks.

"Nothing like a little vandalism to quench that thirst," I scoffed, as I pulled a small coin purse from my pocket. Misaka rolled her eyes and opened her drink as I made my choice. As I pressed the buttons, I then heard her cough and splutter at the temperature of the drink, having expected it to be cold. "Mah tong!" She exclaimed, holding her tongue out in an attempt to cool the aching muscle.

Bots beeped in the distance as my chosen drink clattered to the bottom of the machine. But before I could grab it, Kuroko had clasped a hand around my wrist, teleporting the three of us to the nearby overpass. "Oh, come on Kuroko, I paid for that," I angrily thought to myself, as I then sighed.

"Honestly, was that really necessary?" Kuroko asked, her eyebrows raised as she chastised Misaka gently.

It was during our walk back, the school just on the horizon. That I then realized something. "Oh right, now I remember today is the day of the Tokiwidai system scans. I assume that with my abilities being the same as Misaka, my results will wind up being the same as hers, if not similar. That's a bet I would make," I thought to myself confidently.

The small screen of my tv had done nothing to portray the size and beauty of the school. The red brick gave it a historic feel, while the large airy windows and arched walkways made it a little more modern. I couldn't exactly place the age of the building off the top of my head and silently chastised myself for not knowing more about the anime before watching it.

The two girls and I paused at the sound of an announcement, calling Kuroko and others to one side of the school. My sister and I made our way to the other for our own scans. Thinking back to the anime, I remembered a scene between Kongo and Kuroko that I desperately wished to see in person. "I haven't met Kongo yet, but seeing her fall on her ass would make my entire year. And yet I also remember that she likes hearing herself talk a little too much...still...she is a level 4 Esper with an ability called Aero Hand. If I remember correctly from reading about it, it gives the individual who has it to touch any object, and then send it flying..." I thought to myself

Unfortunately for me, Misaka's grasp on my wrist was tighter than a vice as she dragged me to our areas to perform. Forbidding me from sneaking across campus to witness the scene. Kuroko willingly relayed the story to us afterwards as we sat in the restaurant.

I reveled in the thought of the Kongo falling until Kuroko changed the subject to our tests. I swallowed hard and glanced at Misaka, who delighted in telling the story, proudly declaring the both of us to hold the title of "Railgun."

"How?" Kuroko asked, unable to look me in the eye, after the two of us had shared a misunderstanding in the bath not an hour prior, that neither of us wished to discuss. "Yea, so Kuroko is 13, and she had the nerve to sexually assault me and Misaka...well, let me just add that to the list of things that I am going to have to look out for...because I can always use my electricity to shock her, if she decides to attempt something indecent like that again..." I thought to myself with a sigh.

"Well…" Misaka began, as she prepared to relay to Kuroko about how the results of our systems scan had gone.

Misaka had gone first. Her aim spot on as her shot careened through the water, whipping up waves in its wake.

Soaking the sides of the pool with a torrent of chlorinated water.

The sight exhilarated me more than I had ever been in my life, sending my heart skipping with both fear and excitement at the display of sheer power of the girl.

"Well, I see that her Railgun is just as powerful as it was in the show..." I thought to myself, as I continued to stare at Misaka in wonderment.

The loudspeaker then hummed before a voice came out, clear for all to hear. "Recording initial shot speed at 1,030 meters per second, rapid fire ability, 8 shots per minute, pattern grouping, 18.9 millimeters, overall rating, level 5."

"Hold on here, let me quickly do some math. So a Sud Aviation BAC Concorde is able to travel through the air at speeds just exceeding Mach 2...So if I factor in the conversion...that would mean that Misaka's railgun...just went at Mach 3?! And nothing seems to be damaged either...Incredible," I thought to myself, as my brain raced, while I thought of potential ways in which speed like that could be harnessed.

However, after I had finished my thought, Misaka then turned, her grin wide as effortlessly she tossed her remaining coins into the air.

She then caught them quickly before turning her attention to me.

"Your turn Keiko." She announced, to which she tilted her head to the still rippling water of the pool behind her.

I blinked twice and gulped, my eyes resting on the coins of the exam table next to me.

"Well, I guess it's time to see just how powerful I truly am," I thought to myself, as I stepped past the table, and took a few of the arcade coins, to which I then clutched them tightly.

I then took my place in front of the pool.

I then planted my feet, my stance like Misaka's, firm and unyielding.

I then picked an arcade coin from the bunch, pressing it tightly between two fingers, just like Misaka had done.

I closed my eyes and took a breath, hoping I was channeling the right power I needed.

"Okay, time to see if my suspicions about my Esper level are indeed correct," I thought to myself, as I then opened my eyes, and fired.

And, just like Misaka's shot, it flew through the water, sending waves over the sides of the pool.

I watched with wide eyes as the shot hit the intended target, unable to breathe at the realization of what I had just done.

"Okay, I wasn't expecting that...not to mention that that was a Railgun blast that I just fired..." I thought to myself with a look of complete shock on my face.

Once again, it was then the loudspeaker hummed before the same voice emerged, confirming my suspicions. "Recording initial shot speed at 1,030 meters per second, rapid fire ability, 8 shots per minute, pattern grouping, 18.9 millimeters, overall rating, level 5."

I then heard Misaka whoop loudly behind me, pulling me back to myself with a gasp.

The coins in my hand then became heavier, as I came back to my body to turn and face Misaka.

"Okay, now that's a grin that would make even the Cheshire cat proud..." I thought to myself, as I took notice of Misaka's grin.

I then smirked, as I then copied her move and flicked the coins into the air, and then caught them without blinking.

"So you're both level five?!" Kuroko gasped after we finished telling the story.

"But you can't both be nicknamed Railgun." She added, the two of them coming to the same realization I had already thought of.

"Well, Kuroko does have a point, Misaka already has that nickname...let me think..." I thought to myself, as I then came up with a proper nickname. "Keiko means "blessed child", so I was thinking "Lucky strike"?" I said.

"Lucky strike?" Misaka repeated, testing the name aloud.

"I like it," She said eventually, regarding me once again with a proud smile.

The three of us then sat in silence as we ate before the next event, unsure of what to expect.

I myself having not watched past the third episode of the show, and the girls having not yet lived through the events.

Kuroko then glanced through her schedule, which I knew from the anime to have perverted antics planned all the way through.

"Oh, by the way, I've complied a schedule for you both. Also, someone I know, a girl from the 177th branch, is desperate to meet you both, even if just for a moment."

"A fan?" Misaka asked as she reached over for the schedule, her eyes reading over the information that I did not wish to read.

And after Misaka had stretched Kuroko's face to an unnatural proportion through her pulling on it with frustration. I then realized something. "Okay, so that just happened, it looks quite unnatural when she does that to Kuroko. But, I guess that is what I can expect from being in the world of the anime," I thought to myself with a perplexed expression present on my face.

And in the time it took me to blink, Kuroko had then situated herself on Misaka's lap, having teleported easily.

But before I could pipe up, Ruiko Saten and Kazari Uiharu entered, pulling the attention of the three of us into a welcoming exchange.

The two of them furrowed their brows and looked at me for an explanation of the two girls in front of them.

But I shook my head and shrugged, wordlessly answering the unspoken question.

Later on, at the crepe stand, after the incident at the restaurant. Once we had all sat down, and started eating our respective crepes, well everyone except three of us did.

And this was largely since Kuroko was chasing after Misaka and I trying to get us to take a bite of her crepe. And it was no surprise that neither of us wanted to, I mean, who chooses anchovies as a topping anyway?

Misaka had tried desperately to hide her disappointment at not getting the promised Gekota merchandise that had been advertised outside the crepe stand.

The three of us being nowhere near the first 100 customers.

"Well I can see that she is as obsessed with Gekota as she was on the show," I thought to myself, as I sighed.

However, it was while Misaka and I were offering Saten to take a bite of our crepes, that things started to kick off.

Without any sort of warning, the metal gates on one of the stores, that for some weird reason were down in the middle of the day, violently exploded outwards, creating a massive explosion, taking everyone in the area by surprise.

This of course sprang both Kuroko and Uiharu into action. But, as Kuroko adorned her Judgment officer sash, and as Misaka offered to help, only to be told to stay put by her.

I then went up to Misaka, put a hand on her shoulder and decided to speak up, "don't worry Misaka, we'll get our chance, you just wait," I said.

The three men allowed her a moment to say her usual introduction, all the while sniggering at the small girl in front of them.

One man charged once she had finished, assuming to easily tackle her to the ground.

But Kuroko was quicker, sidestepping out of his way and to his side. Grabbing his hand and his trailing foot, she manipulated his own leverage to flip him over and onto his back.

Winding the man instantly as his back dropped flat to the hard ground.

It was at this point, as Saten, Misaka and I watched from the sidelines, that Saten decided to speak up, mentioning Kuroko and how she had just dispatched the robber. "Well that's Kuroko for you," I said as I cracked a smirk.

It was at this point however, that the smirk wound up leaving my face, as it was found out that one of the kids, that had been on a field trip in the area when the robbery had taken place, was nowhere to be seen.

It was decided that Misaka and I would help look for him, and after some convincing from Saten, she wound up joining in as well.

However, from what I remember from watching the anime, this would wind up doing more harm then good.

It was while Misaka and I were searching the bus that had been used for the field trip, and Saten was searching the area around the bus, Saten wound up catching sight of one of the robbers snatching up a kid and taking him down the street towards a car.

It was at this point, after trying to get me and Misaka's attention, that Saten decided to take it upon herself to pursue the robber and try and retrieve the kid.

However, both Misaka and I wound up catching sight of the robber fighting with Saten for the kid, just in time to see him hit her.

As I watched, unsure of how to proceed, I heard the familiar crackle of electricity next to me.

I turned to Misaka and took a step back at the visible rage on her face.

"Shall we?" She asked, as if already knowing me to be ready.

Quickly, I nodded, and followed her off of the bus, and halfway down the street towards the car, which had now begun to drive away.

I then pressed the arcade coin from my pocket between two fingers.

Despite our matching abilities, I knew by her sheer determination, that she could live up to the reputation that would plague her after her next action.

But, myself, I wasn't sure if I could.

Reputation, however, in this moment, didn't matter.

What mattered was protecting the lives of anyone this man was willing to sacrifice for his loot, especially now he had a fast vehicle.

The task at hand, I knew to be big, but it was important.

"Is there anyone else in the car?" I asked as the electricity built.

Her response was a smirk, her eyes darkening.

I had seen this in the anime, her rage.

But nothing had prepared me to witness her power and her fury first hand.

She was magnificent. Scary, but magnificent.

"Then let's get him." The fool committed an illegal U-turn, heading back toward us as we stood side by side, blocking the road.

I noticed him to be accelerating as he charged for us, his head hunkered down as he clearly assumed us to be playing chicken.

Together, my sister and I flipped our coins.

Together firing our Railguns the exact moment our respective coins rested once more between our fingertips.

The electricity shot out of our fingertips and straight towards the car.

Lightning lit up the man's face, illuminating his terror before it struck, sending the car and its temporary driver up into the air over our heads.

Together we watched it soar, time seeming to stand still until the vehicle landed nose first.

Stopping instantly. As a crowd formed around the scene, I realized that my presence had upset the balance. I likened myself to a rock being thrown into a still pond, sending ripples of trouble into this world.

I knew it not to be my fault; I had never asked for this. But I swore that for as long as I was here, in this world, that I would only help where I was needed.

Silently promising not to cause any more ripples.

And yet, something else didn't seem to be right with all of this.

"Who am I , and who am I as Keiko? I will need to ask Kuroko to look up my information at some point," I thought to myself.
