Author's Notes: This is probably my second fanfiction in this website (The Last Stand doesn't count since it's a one shot). I got hitched to reading and watching both series of To Aru Kagaku No Railgun and To Aru Majustsu No Index. I needed a new story to work on, giving me different perspectives and techniques to apply along with my other fanfiction. This is the first anime that Im writting a fanfiction for that I heard purely through subs. I can't find any suitable replacement for several japanese terms, so they will be present. This story continues on from the endings of both Railgun and Index animes. I haven't gotten a chance to read the light novels due to no translations. So this is why I start the plot from where I've understood the story so far. This story won't be as long as my other in progress fanfiction. I hope you all enjoy reading this prologue and do be forewarned that it'll take some time for me to update this.

Time Index

"Hey hey, would you like to play with us?" Misaka Mikoto ignored the short fat man and the rest of his lackeys. She was in an overcrossing, all alone by herself enjoying the wind. Initially, she was. Now there are six men, all from not too good backgrounds enclosed around her.

'Don't they have other girls to chase?' She was like a delinquent magnet. All of them seem to go after her all the time as though it was a natural phenomenon. No matter, she'll deal with them the way she normally did. She stood up and just did her thing, zapping them to an instant knockout.

"That burst of energy appears to be excessive. Misaka states in analysis." Misaka turned to see Misaka Imouto to her left. She is a sister or rather a clone of herself. Initially they were to become a clone army of the Level 5 Railgun. Results were undermining and they were shifted instead to die as guinea pigs for an experiment of creating the Level 6. The sisters were saved by a level 0 student, Touma Kamijou who defeated the top Level 5, Accelerator. The project was canceled and now, she and the remaining Misakas are spread around the world as they explored the new world they were never supposed to see.

The original Misaka raised her eyebrow. "Well, they were asking for it." Messing with Misaka Mikoto is asking for a death wish.

"Even so, excessive current can cause cardiac failure and eventually death. Misaka informs."

She backed away from the railing. "I know I know. They'll be fine though. They always will." Sirens blared from the highway below them. A car drove past the overcrossing, clearly speeding. Police cars were in pursuit. She looked as they went past in their chase of cat and mouse. "Academy city is not safe these days."

"From statistical data comparison, the flux of criminal activities is on par with other cities throughout the world. Misaka states clearly." Being connected to the other Misakas grants an indirect ability of acquiring a great deal of information anywhere on the world provided there is at least one Misaka present within the desired region. It's very helpful on staying up to date and keeping track on things.

"…" Misaka was silent for a moment. She looked at her sister, eye to eye. "Before I met you sisters, things were very simple and considerably safe. Thieves, thugs, I'm not afraid at all of them." She stepped closer to Imouto "Now after the closure of the experiment, I don't know what other monstrosity they can create with my DNA." She never found the samples or replicas the scientists used to create the MISAKA Army. "Only God knows what they are up to now."

Her clone looked with a blank stare, not truly capable of emotions yet. "Things will be fine, provided we stay together as a family." She gave a faint smile to bolster the fact.

Misaka smiled as she hugged her other self. "We will...we will."

Kuroko let out a sigh as she walked down the public streets of Academy city 'Geez, why are there so many troublemakers today?' It was just days since the New Year celebrations. Judgment as always was actively performing its duties for the general public. Today is one of those odd days for Kuroko. She had subdued six criminals with other districts reporting similar numbers. Adding to that were additional non criminal troublemakers such as litter and vandalism. She frowned at the air in front of her. 'Some of that is probably due to Onee sama…' Well, no one seems to have an explanation on the surge of illegal activity. 'Are they just coming out from the festive season?' She let out another sigh. It was a good thing her patrol's about to end then she could take a break at the office. Even so, Judgment is going to have hard days coping with all the workload.

She heard running footsteps behind her. Naturally, she turned to see a man jumping towards her. 'What on earth?' She reacted in self defense, striking a fighting posture by spreading her balance and bending her knees. She waited in those milliseconds for the first move only to see the man landing on the railing beside her and ran on. Now confused, she looked at the man run on. She sighed. Things are not what they are to be. Too many fights today probably made her jumpy today. She relaxed as she looked at the guy. 'What's with this weirdo running all over the place?' The weirdo was in a school uniform, wearing a green hip pack at the waist and black shades to match his black Chullo hat. 'The school uniform isn't suited for such running.' She was prepared to dismiss him and get back to the office when the person jumped off the end of the railing, performing a mid air spin…to land his back against another man's chest.

The other was familiar to her. She squinted to get better focus. 'Wasn't that the guy from the Level upper case?' She remembered him, the blonde guy who could bend light around him. Remembering that brought the satisfaction of ingenuity for demolishing an entire building with just glass. "Woops. Sorry about that." The runner apologized. Kuroko already knew there's going to be some trouble.

The light bender snarled "Who do you think you are, being a bug by bumping into people?" He grabbed the slightly shorter guy by the collar. "I don't like annoying pests like you."

Kuroko sighed 'Oh boy, here we go again.' The guy is going to beat up the younger, skinnier guy if she didn't do anything about it. As she was about to intervene, something unexpected occurred. She barely noticed a blur of the runner's hand. It reappeared just below the man's chin, with a pistol. It was coated in primarily silver with a gold block bearing an inscription in italics above the trigger 'SPEAGLE'. She felt her heart jump a beat.

The gun's barrel touched the man's chin "Let me go, please." Being surprised by the gun's appearance, the thug let go. "Thank you." Kuroko saw the weapon disappear in a split second. The man ran on as though nothing happen. Kuroko's trouble just got worse. 'A student with a gun in his hands'. The situation just got dangerous. If she doesn't arrest and confiscate it, the student will do bad things with it. 'Definitely will.' She ran forward after the guy.

The blonde was growling, definitely pissed off from the situation. She ordered "Move aside unless you want to be in another collapsing building." The guy obliged, clearly remembering the teleporter. She chased after the running for apparently no reason man. She teleported and covered the distance very quickly. She appeared behind him, several paces behind. "Stop where you are."

The runner stopped and turned around "Is there a problem, Miss?"

'Yes…. a major problem.' She displayed the Judgment tag on her arm. "I'm from Judgment and I need to confiscate that gun of yours."

The student gave a sigh "Not again…" He flexed his legs "Well then, if you want it." He turned around "You got to catch me first!" Kuroko shrugged and teleported several spaces before him. He was surprised, catching it from the tone of his voice. "Okay…a teleporter. Kuroko didn't answer, silently watching the man's reaction.

'Will he give it up or use the gun?' Her hunches were on the later. You have a deadly weapon, so why not use it? It was contrary to her expectations.

"Let's try that again." He spun around and become a blur. She could see the blur running away from her at speeds beyond a normal human.

'A speed based Esper eh? It's time to catch another one of these guys.' She teleported after him. She connected to her partner through her phone in mid teleportations. "Uiharu, I'm after a runner at the 7th street of Furiai Plaza! Keep track of him, you have my signal." For every teleport she made, the man has made seven steps. She was gaining on him but slowly. It was too slow for her taste. She had to chase someone equally fast before and it was time consuming, traveling all over Academy city. She'd like to end it as fast as she can.

The gunman dashed into an alley. 'That won't help you escape.' She asked as she entered the alley "Which way did he go?"

Uiharu voice came through her earpiece "The cameras don't show anyone entering or leaving yet. He should still be inside." She stopped to listen for footsteps, a clear easy sign to finding the path in such echo prone alleys. The footsteps were to the left. No, it is to the right. No, in front and behind! The footsteps are everywhere! Even the spot above her had echoes of footsteps. It was confusing for such a thing isn't possible! She took the best option and teleported up to the nearest roof.

"Anything yet?"

"Nothing on the cameras." There was no one in sight across the horizon of the roofs. Kuroko grit her teeth. She lost the trail of footsteps as well. The cameras don't cover the roofs as well. The student with the gun has vanished. She looked around a bit more but there was no trail she can rely on. She'll have to search for him in the big city through detective work. She'll go through the entire city, from corner to corner until she found him. 'No one runs from Kuroko.' She spoke into her phone.

"I lost him. I'm heading back to the office."

Kuroko plopped onto the sofa, exhaling a long and slow breath. Uiharu handed her some tea as she sat beside the teleporter. "So how did he escape from you?"

Kuroko gave a sigh "he tricked me with many paths of footsteps. In such narrow alleys, there wasn't a way to find the real one." She then drank the tea.

Uiharu asked the important question "What kind of esper ability does he have?"

Kuroko gave the honest answer "I don't know now. I thought it was a speed based esper but an esper like that can't make such a deception." Uiharu nodded and contemplated on the issue.

"Could it be a Dual Skill?" She suggested out of the blue.

Kuroko disagreed "You know what the scientists say, practically impossible for a Dual skill to exist."

"Even if there is less than one percent, it still could be the case." Both girls turned around to see their senior standing behind them with a mug of coffee.

"Even so Konori sempai, isn't it best to investigate more plausible ideas first?"

Konori Mii nodded "I'm not disagreeing with that." She took a sip "Anyway, this lad you mentioned has a gun in his possession?" Kuroko nodded her answer. "Then it's best you prioritize this case immediately. Other districts are reporting major crime surges, some with illegal firearms. Who knows how a student can get access to such weapons. The complications are severe." Although espers generally have better self defense skills, there are espers whose skills aren't for combat and there are also non espers in the city. Such weapons would be catastrophic if there are more students with them and used without hesitation. Death could climb to dozens or worst by just one gunman, with clear examples in the past all over the world. If there are more of them, the possible consequences are clear enough. "Find out who and where this guy is. I'll inform the other districts to keep an eye out."

Her juniors gave a determined nod. They know what to do. Find and arrest the student with the silver gun.

"Have you found him?"

"Not yet."

"Time is short. Remember that."

"We're doing our best but he's deep in hiding."

"Then get to it. Preferably I want him alive but he may stay dead for all I care."

*Clack*

"Nothing too well I take it?"

"They are problems but nothing that will ruin my day."

"Good. How goes the rest of our plan?"

"They are proceeding as planned. Now….we shall wait for the sown seeds to bear fruit."

I hope it isn't too short for a prologue, it feels that way for me.
