A/N- Well here's another story that's likely to just be a one-off. I really like A Certain Magical Index, and Accelerator is one of my fav OP characters. This takes place after he is defeated by Touma but before he encounters Last Order. I hope I'm able to portray him properly.

Other than that, I hope you enjoy and be sure to leave a review.

He was born with a burden, a curse. The stigma of having power. He was so strong that no one could stand beside him, no one could be his equal, no one to call a friend. He had the ultimate power. Even if the apocalypse came in the form of a great explosion, he would still remain.

But for all the protection his power provided him with, he could never use it to save another. His power was meant to keep him safe... isolated. Cut off from everyone else.

All his power ever did was get him enemies. People who feared his power tried to put him down. People who sought his title would challenge him. None were able to stand against him. So he decided; 'if they won't stop challenging me because of my power, then maybe they'll stop if I become so powerful that they wouldn't dare challenge me. Maybe they'll stop if I were to become a god.'

It was with this in mind that he was chosen to take part in an experiment. A test to see if he could evolve to a higher existence. He was tasked with slaughtering 20,000 clones of the level 5 esper Railgun. According to the calculations made by Tree Diagram, if he was able to kill them all, then he would successfully shift to a level 6 esper. And that would make him the strongest person in the world without question.

Maybe then, he would be free from his curse. Maybe then, he would finally be able to make friends.

But it all came crashing down one fateful night. The night that the weakest level 0, challenged him, the strongest level 5. The outcome of such a battle should have been obvious. He should have been able to utterly onesidedly annihilate the puny whelp who dared to stand against him.

But that was not the case...

Against all odds, the level 0 had managed to best him, defeat him in one on one combat. And with that, the boys title of 'strongest esper' was shattered.

Now the challengers came crawling out of the woodwork. All of them now certain, that if a level 0 could beat him, then they could as well.

And so it was that all of his hard work, the countless clones he had killed, the time wasted on that sick experiment, it was all for nothing.

He wasn't exactly sure how he should feel. Sure, he was now annoyed by the countless attacks he had to endure from wannabe espers who wanted his title, but they were more of a slight nuisance.

That was of course, until the night the he appeared.

The teen known as Accelerator was heading back to his apartment, a bag of food from the local convenience store slung over his shoulder. He had pale skin, moppy white hair, and red eyes. He had a small frame and looked as if a slight breeze might be enough to knock him over. But despite his appearance, he was still the strongest level 5 esper in Academy city.

As he made his way home, he took note of the person who was not so subtly following him.

'Great. Another shit head who wants a shot at the title.' he thought as he continued on his way, doing his best to ignore his stalker. Until he grew the balls to actually attack, Accelerator would leave him alone and give him the chance to rethink his actions. But as soon as he attacked, Accelerator would show no mercy.

The stalker finally built up the courage to approach, and as such Accelerator turned to acknowledge him. "You must have balls of brass to be doing this. You do know who I am right?" Accelerator asked with a scowl.

The person standing across from him was wearing a black hooded cloak with the hood shadowing his face in the already dark night. "I am well aware of who you are, Accelerator." the figure said.

Accelerator took note of the voice of his challenger. It was not that of a teens, but rather it belonged to an adult. The only ones in Academy city who were espers were the students. So why was a powerless adult challenging him? Then again, that level 0 challenged him and won, so maybe this guy had figured he'd give it a shot.

"And I must say, it has taken me quite a while to find someone of your caliber. A person who can perform the task I require." the man spoke.

"Hnn? I don't know what you're on about, but I ain't doing jack shit for you. So you can just piss off before I smash your face in." Accelerator threatened as he turned to leave.

"I'm afraid... that you don't have a choice in the matter." the man said as he reached into his pocket and pulled out a key. It was a rather intricately designed key that had a skeleton head on the grip and a strange pattern for the double-sided keyblade.

"Oh yeah? And why is that?" Accelerator asked as he gave the man one last glance.

"This is why." the man then swung the key through the air, ripping open a tear in the very fabric of space in the process.

Accelerator's eyes widened at the strange ability. Moreover, how was an adult using an esper ability? The tear widened and formed into a portal of darkness. Then came the pulling sensation. The portal was trying to suck Accelerator in. Before he knew it, his feet were off the ground and he was flying towards the darkness.

As it enveloped him, he heard the man say. "Help Night Raid."

When Accelerator's vision returned from the blackness, he saw that he was plummeting back down to the earth from a great height. Below him was a massive city of some sort, but it definitely wasn't Academy city.

"Son of a bitch." groaned Accelerator as the ground grew ever closer.

Activating his reflection ability, he simply fell to the earth like a crashing meteor. A loud crash heralded his arrival as his body impacted the street. Getting up from the rubble and dusting himself off, he noticed that he had some gawkers. There was a petite pink-haired girl wearing a pink dress and holding a massive rifle of some sort, along with a busty purple-haired woman who wore a purple cheongsam and was holding a massive pair of scissors.

"What the hell you looking at?" he asked, to which the girls slightly recoiled. "You never see a guy fall out of the sky before?"

"Who are you?!" came a voice, but it wasn't coming from either of the girls. Accelerator turned and saw a brown haired girl who was wearing some kind of military uniform. With one hand she pointed at Accelerator, her eyes fixed in a glare, and in the other hand was some bastardized combination of a gun and a tonfa. But what caught Accelerator's eyes, was the massive beast thing that stood alongside her.

"The fuck is that?"

The creature growled at Accelerator.

"Are you with these assassin scum?!" the girl asked.

"Assassins?" Accelerator raised a brow. Those other two girls didn't exactly look the part.

In her haste, the girl seemed to take his vague response as an answer, and decided to act upon it. "Very well! Then you shall die in the name of justice as well!" she yelled as she gestured for the beast behind her to attack. "Get him Koro!"

With an blood-curdling roar, the beast (named Koro apparently) charged forward and was on a direct collision course with Accelerator. Normally it's snapping maw filled with razor sharp teeth made for an utterly terrifying visage of certain death for whomever it happened to have in its sights, but to the apex esper it might as well have been a chihuahua.

The two other girls looked on in slight alarm and concern as Koro bore down on the white-haired teen, but neither made a move to intercept the creature. It was a perfectly logical response in Accelerator's mind. Even though the pink and purple girls seemed to have been in the middle of a fight with soldier-girl and her steroid-pooch, it wasn't likely that they would be willing to risk their lives to try and save a complete stranger who had the misfortune of stumbling (read: crashing) into their fight. Sure, they felt bad about leaving him to his fate, but that didn't mean they would try to defend him and risk giving the combat advantage to their opponent. After all, it is much harder to fight when playing escort to a civilian.

Fortunately for them however, their conscious need not be burdened from failing to save the albino teen, as he was more than capable of defending himself.

Koro's massive jaw opened up and bit down on Accelerator the second it was within range. The brown haired girl grinned madly at what appeared to be the successful 'execution' of the 'assassin'. At this point she was about to boast and croon about how she had successfully killed another enemy of the Empire in the name of justice. Rub it in the faces of those Night Raid scum that justice will always prevail and that death was the fate that awaited all who opposed it.

However a moment later the rant died on her lips.

An explosion of blood erupted from the position of the white-haired teen as Koro bit down on him. At first the three spectators thought it was from the boy being crushed to paste by Koro's teeth, but then they realized that there was far too much blood for it to have been from just one person.

As the red mist dissipated, all were surprised to see Accelerator standing there without a scratch on him. Not even his clothes were torn or bloody. Koro on the other hand was missing its head along with its upper torso. Its arms were barely hanging on to its body by its shredded shoulders. Yet despite this, the creatures flesh still writhed about as if the major injury wasn't the least bit deadly.

"W-What the hell?!" shouted the military-girl. "How the hell are you still alive?! What did you do to Koro?!" she demanded as she aimed her gun/tonfa at him.

Accelerator lazily turned his head to the girl, an act that displayed just how much of a threat he considered her to be. That is to say, not at all. "Well, it was coming at me with the intent to kill, so I just returned the favor." he answered as he reached into his shopping bag and pulled out a can of juice. As he opened the can and took a sip, he watched with a morbid fascination as Koro's body began to reconstitute itself. "Interesting. It seems to be capable of rapid cellular regeneration. Though the rate and amount it's regenerating is completely unnatural. It is beyond obvious that it is some sort of Frankenstein abomination of science, so it is more than likely that it has some sort of high-power energy core that is providing it with the energy to replicate its cells so fast." he noted in observation. Being the strongest esper also meant that he was the smartest, so it was easy for him to draw a conclusion about the beast. "I recall something similar having happened with AIM fields during the level-upper incident."

"What are you babbling on about?!" yelled the brunette. "You know what, forget it! JUST DIE!" she screamed as she fired her gun/tonfa at Accelerator. Not even a moment passed since the first bullet left the barrel and she felt a sharp pain in her shoulder. Turning her gaze towards the source of the pain, she noticed that she had a bullet-hole in her shoulder. Raising her free hand up to grip at the wound and slow the bleeding, she cast her gaze around to search for who fired the shot. However despite how hard she looked, the only people present were the four of them. What's more, the only sound of a gunshot came from her own weapon.

"You know," Accelerator said as he returned his attention to the brunette. "Has anyone ever told you that it's rude to interrupt someone. Especially with a gunshot."

The girl faltered slightly when his red eyes bore into her own. His previously uninterested attitude was slowly warping into something more sinister. The ever so slight sneer that was working its way onto his face, the gaze that viewed her as nothing more than an insect to be crushed, and the dark undertone to his voice all screamed that if he wasn't a combatant before, he sure as hell was one now.

"Because for your information," he said as he lifted his foot up slightly. "I have killed people for far less." his foot then descended back to the ground and as soon as it touched down, Accelerator rocketed forward at inhuman speed.

It was only thanks to the girls fast reflexes that were sharpened through hellish training that allowed her to react fast enough to dodge the initial assault. She bent backwards underneath the white-haired teens swipe before quickly backstepping to put distance between the two of them. Despite how weak and pathetic his attack looked, she had a gut feeling that if he managed to slap her with his hand just then, that she would be nothing more than a stain on the street. For the first time in her life, she felt like she was no longer the warrior of justice that hunted down criminal scum, who was destined to always come out victorious and ensure that justice prevailed. For in the face of the weak looking teen in front of her, her guarantee of victory was being called into question. She had to consciously force herself to stop trembling in the presence of this evil. What kind of warrior of justice would she be if she turned tail and ran now? No, she just needed to hold out until her reinforcements arrived. Then they would overwhelm him with sheer numbers. But seeing as how it wasn't likely that she could hold him off long enough in combat, she would have to settle for trying to stall him. And maybe she could get some useful information while she was at it.

"I must admit, you much stronger than you look." she growled out. As much as she hated giving her opponent a compliment, it was the easiest way for her to try and divert his attention, if only for a moment.

Accelerator let out a slight scoff at her words. "Tell me something I don't know. When you're the strongest person in the world, you would have to be an idiot not to know it."

"You?" the girl snorted lightly. "The strongest? Don't make me laugh." she said as her sneer intensified. "The title of strongest belongs to the ones on the side of the righteous! A vile piece of assassin filth like yourself could never hope to match the iron might of the law! We crush all those who oppose our order with the unstoppable force known as JUSTICE! And standing at the pinnacle of that justice is the greatest warrior who ever lived; General Esdeath!" shouted the girl in a fit of madness. "None can stand against her strength! Those who are foolish enough to do so are mercilessly destroyed! It doesn't matter what kind of teigu you have, you will never be able to defeat us! KORO!"

The snarl of rage coming from behind him alerted Accelerator that the beast known as Koro was finished recovering and once more was ready to attack. Turning his head to face the beast, Accelerator lazily raised his hand up and pressed his middle finger against his thumb. "Piss off." the moment Koro got within arms reach, Accelerator flicked his finger out. To everyone's surprise, the slight impact was enough to send the abomination flying away. It was almost akin to being shot out of a massive cannon as the beast flew far into the distant sky and away from the esper.

The soldier girl collapsed to her knees in shock. The frail looking teen in front of her had just sent her 'pet' soaring across the city like it was nothing. A part of her mind was able to register the fact that the female assassins had since retreated to the treeline at some point in order to either prepare for a full retreat, observe the white-haired boy, or flank around and attack her from behind, but the majority of her focus was on the monster in front of her. For no normal man could possibly be capable of doing something like he had just done. "I-impossible..." she muttered in disbelief.

"Is she a God?"

The question was initially lost on her as she was still trying to process her current situation. "Wha...?"

The boy stepped forward slowly, taking all the time in the world to do so. "I asked; is she a God?"

"W-who?"

"General Esdeath." responded Accelerator. "You say that she is the strongest there is. That her power knows no equal. That no one in the world can stand against her. So I ask you; is she a God?"

The girl, trying to muster up some resistance, let out a half-baked snarl before answering. "Of course not. There are no Gods. But that doesn't change the fact that she is the strongest."

Accelerator was now right on top of the girl. His bangs cast a shadow over his eyes as he stared down at her, but his red eyes seemed to glow faintly in the darkness. This, coupled with the grin on his face, made him all the more intimidating. "Then I have nothing to worry about. After all, since I am the closest thing to God, then the only one who could defeat me would have to be a God."

"You think yourself a God?!" raged the girl. "Such arrogance! Call yourself whatever you wish, but know that none of it matters in the grand scheme of things! You will fall to our justice! Your body will be left broken and bloody and you will be begging for forgiveness for your crimes! But there will be none to be found! All that awaits you will be a painful death and an eternity of punishment for your evils in Hell! I looked forward to hearing your cries of agony as we subject you to every form of torture that there is! The amount of blood on your hands will be matched with your own! You will-!"

Her rant was cut-off as Accelerator grabbed her by the throat and lifted her up.

"Has anyone ever told you that you talk too much?" he asked with a disinterested tone. "You can go on for as long as you want about my crimes, but you don't even know the half of it. I've spilled enough blood to fill oceans, and I did it all without a hint of remorse." he then pulled the girl closer to the point that their faces were nearly touching. "What makes you think I'll lose any sleep over ending one more life? What makes you think I'll lose any sleep over ending your life? In the end, it'll just be another body on the pile." as he said this, he slowly began to apply pressure to her neck and crush her windpipe.

"Ghck! W... Who... are you?!"

"I am Accelerator, the One Way Road."
