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. Sounds of fighting causing me to jump, closing my eyes tight once again. "Hey!" I heard a familiar voice call to me. "You gotta focus!"

I opened my eyes and glanced up to see Mikoto Misaka staring at me with wild eyes as she gestured frantically at the thugs surrounding us. "Sis, we got a situation here! I don't need you zoning out, girl!" "Britney Karbowski?" I asked myself, recognizing the voice actor behind the girl. "Girl?" I realized she had said to me.

Knowing 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 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. "Something else to get used to?" I asked myself as my eyes scanned the rest of me.

"School uniform?" I sighed, school being the one thing from my childhood I had never missed. I looked up at the girl 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 pulling me from my stupor and back to the fight.

Having only watched three episodes of the show, the third one through droopy eyes, I didn't know much about the world around me. But I knew of her. The ace of Tokiwidai, Railgun, electromaster, third ranked level 5 esper. The tsundere with a very short fuse.

By default, I too should possess the same abilities as her through our sisterly bond. I inwardly cringed at the thought. But, with the two of us in an alley surrounded by thugs, there was no way for me to assess just how powerful I was without damaging her in the process.

Taking a breath and calming my mind, I held my hand out to match her stance. I felt the electricity course through the air before it seemed to course through me. 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 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 realized after the last one dropped that only I had attacked. Her gathered electricity, having not yet left her palm. As if someone had toasted a piece of bread on the highest setting, the alleyway filled with the stench of burning. The smell penetrating my nose to leave a memory I knew I could never erase. The seconds ticked by, but still the stench lingered. I crinkled my nose and sighed, hoping I wouldn't have to get used to it.

The sound of shoes hitting the sidewalk caused us to stand defensively once more until a familiar face coming around the corner made Misaka ease. I, however, stood my ground as my blood ran cold. "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 and-" She stopped 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. "Hey Kuroko." Misaka gave a polite smile, electricity crackling through the bangs of her hair.

"Sissy…and Keiko, you're here too." I resisted the urge to turn and shrug, instead choosing to raise my hand and smile awkwardly. "Keiko." I repeated to myself. "Add that to the list of things to get used to." I inwardly sighed.

I watched Kuroko's eyes drift down to the chest of my sister and back swiftly, thinking no one saw her quick glance. "And I thought Infinite Stratos's Tabane was perverted." Thinking against making an enemy of my sister's friend. I decided to suppress my feelings of dislike for the clearly obsessed girl, and instead attempted to make light of the situation. "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. Misaka giggled at Kuroko's pink cheeks, the officer also giving a small shy smile at the thought. Silently, the three of us 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, she coughed and spluttered 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, I paid for that." I 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 realized today to be the day of the Tokiwidai system scans. I assumed that with my abilities being the same as my sister's, my results would be the same, if not similar. "That's a bet I would make." I told 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 hadn't yet met Kongo personally, but to see her fall on her ass would make my entire year.

Unfortunately for me, my sister'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 girl falling until Kuroko changed the subject to our tests. I swallowed hard and glanced at my sister, 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. "Well…" Misaka began.


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 that sent other students fleeing the electrified droplets.

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.

The loudspeaker 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 millimetres, overall rating, level 5.

Priding myself on my math skills, I did some quick calculations. I contained my gasp when I realized Misaka's shot to have traveled at Mach three.

Three times the speed of sound, and yet nothing appeared too damaged.

"Incredible." I thought to myself, my brain racing with potential ways speed like that could be harnessed.

Misaka turned, her grin wide as effortlessly she tossed her remaining coins into the air.

She caught them quickly before turning her attention to me.

"Your turn, sis." She announced, tilting 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.

Stepping past the table, I took a few in my hand, clutching them tightly.

I planted my feet, my stance like my sister had, firm and unyielding.

Then, I picked a coin from the bunch, pressing it tightly between two fingers, just like she had done.

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

When I opened my eyes, I fired.

Just like Misaka's shot, it flew through the water, sending waves over the sides towards other students.

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

Once again, 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."

Misaka whooped loudly behind me, pulling me back to myself with a gasp.

The coins in my hands became heavier as I came back to my body to turn and face my sister, who's grin reminded me of the Cheshire cat.

Smirking, I copied her moves and flicked the coins into the air, catching 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.

"Keiko means "blessed child", so I was thinking "Lucky strike"?

"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 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 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 avoiding the information neither of us wished to read.

In the time it took me to blink, Kuroko had situated herself on Misaka's lap to read with her, the girl teleporting 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.

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 coin from my pocket between my 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 exactly was Keiko?

I would obviously need to do something further investigating on this.
