POWER!...thats just my catchphrase to literally anything. But anyway, Its great to finally be an active writer to this wonderful community. This community that is perhaps the largest communal celebration of imagination, creativity, intelligence and little ponies. This is my first Fanfic, I hope that you will enjoy and give constructive criticism so that I may improve my writing skills and continue to give my readers quality work to...well, read about.

Story motivation: Got the idea of the story when I noticed the lack of stories that delve into the new-found familial relationship between Accelerator and The SISTERS. After watching Heavy Rain, the story of a father risking his life to save his brat, I wanted a similar story that involving Accelerator and the people he treasures. As mentioned before, I found no such story and decided to make one instead. Also, I felt that Volume 22 did not give a satisfying conclusion to Accelerator's connection to the Darkness Of Academy City thus I aim to create the best possible scenario for Accelerator to give those assholes the grandest 'flip the bird' of them all.

Disclaimer: I do not own To Aru Majutsu No index. If I did, you should all be watching season three now

Chapter One

Location: Academy City, District 19, Abandoned Street.

Time: 04:43, November 15th

Heavy showers of rain shrouded District 19 in an impenetrable veil of mist that severely limited visibility. Unlike the other Districts that were well structured and lit, District 19 has been on a decline for years due to lack of maintenance thus the streets were nearly pitched black in the darkness of the early morning with only the occasional lightning illuminating the deserted blocks for a brief moment.

Along the road, headlights from a speeding car shone through the darkness but the storm was too heavy, making it difficult to even see a few feet ahead of the vehicle.

But that did not matter to the driver, Professor Kyousuke, who sped through the streets as beads of cold sweat poured down his face. He could barely keep his hands from shaking with fear, causing his handling to be dangerously unstable. Occasionally, he turned his head to check if the source of his fear was still pursuing him.

'What the hell does that monster want with me!?' He frantically thought. 'The Experiment has been scrapped a long time ago, there's no reason to go after me!'

Looking back once more, Professor Kyousuke slightly calmed down when the road behind him was empty. Despite the poor visibility of the street, his pursuer had a distinct albino appearance that allowed the street's darkness to be proof of the monster's absence.

Turning his attention back to the road, the professor was about to breathe a sigh of relief but he suddenly choked at the sight before him. Despite the blurry visage, The Monster was already ahead of him, effectively blocking the vehicle's path. Unable to react rationally to the unexpected appearance, desperation took precedence over logic and the professor floored the pedal, intending to run over the monster. In a few seconds, the car quickly closed the distance between them but right before impact, the figure slowly raised his hand and suddenly…

CRASH!

The car's bonnet was instantly crushed with overwhelming force, grinding the vehicle to a halt. The Professor himself was left relatively unharmed due to the reliable airbags but he was far from feeling relief. In fact, he was probably wetting his pants as the current situation was processed in his brain.

He was trapped. Trapped like an animal awaiting the slaughter.

An ear-splitting crunch creaked loudly before the front half of the car was torn away like a page torn from a book. Professor's Kyousuke's compressed face was freed from the suppressing airbags but that only meant nothing stood between him and the monster, who casually threw the front half of the car over his shoulder like simple trash before slowly walking towards his prey.

Fear petrified Kyousuke as the monster approached, with every step closing the distance and much to his regret, Kyoususke could once again make out the Monster's features.

Snowy white hair was drenched over his face, although they did not hide the piercing crimson eyes that were seemingly glowing with rage. His thin physique gave off the impression of a weakling but he was far from that. He is the Most Powerful Esper in Academy city, Greatest of The Level 5s.

He is The Accelerator.

Kyousuke's heart was on the verge of breakdown from this harrowing experience, he could barely think coherently as the feeling of terror that Accelerator emitted shattered his mind.

Wordlessly, the albino gripped the Professor's throat and pulled him from his car and out in the rain. Lightning flashed as the Professor was held at the mercy of Academy City's Strongest Esper, highlighting his expression. Absent was the psychotic grin that he was infamous for. Instead, pure and unadulterated hatred was burning in his eyes and his clenched teeth seemed to be the only indication of restraint.

The Number One was furious.

"Please Accelerator just listen to me!" Desperate to save his life, Kyosuke begged. "We had no idea that the Experiment was-".

"Spare me the bullshit, scumbag." Accelerator growled. "The pigs that I hunted before you squealed the same excuse and I'm already at the limit to how much shit I can endure in this fucked up situation"

Accelerator tightened his grip on the throat of the Professor, who gasped in pain and tried fruitlessly to loosen the monster's fingers.

"For two fucking years, you had the power to shape the fate of ten thousand lives and you could have stopped their suffering, you could have stopped me…" Momentarily, Accelerator's rage faded and was replaced by a melancholic expression, which showed a hint of sorrowful regret. But as quickly as it disappeared, the rage returned to his eyes. "But none of you even lifted a fucking finger! You knew the fucking truth and yet you just fucking watched!"

"The…Experiment…was….only…meant….to…..strengthen…you." gasped Kyousuke as he struggled in Accelerator's steel grip. "They…weren't…supposed….to….live…longer…than…intended."

Accelerator immediately slammed the Professor to the ground and without giving his victim a respite; Accelerator repeatedly pummeled the Professor's face with his fist. "Don't fucking say that! I will save those brats even if it costs me my tainted life!"

Accelerator's punches began increasing their tempo. "Even if I have to make an enemy of the entire world, I'll give those girls the bright future that they deserve, a future where shitty monsters like you and me will not trample on their lives!"

With a final punch, Accelerator allowed the Professor Kyousuke to crash to the ground. The latter's face was almost swollen beyond recognition from the cuts and bruises that Accelerator's vector-enhanced punches inflicted, causing him to be incapable of coherent speech.

As the Professor groaned in agony, Accelerator kneeled down and sadistically whispered. "Before that, I will first exact retribution for those lives that were destroyed from this atrocity."

"Pleesh…I don't….want…to…die." The professor continued begging despite his broken jaw. "We…were…simply…*cough*…doing our…jobs-"

" No…you bastards have created your own hell and I'm the demon that will drag every fucking one of you down."

Inserting his finger forcefully into a deep cut within the Professor's bloodied face, Accelerator unveiled his terrifying twisted grin while ignoring his prey's cries of pain.

"AAAAAAAAAAHHHHHHHHHHHHHHHHHHH!"

"Painful? You know nothing of pain yet!" Accelerator's maniacal grin grew larger. "Now feel the suffering and torment that they felt, feel the pain that you made me cause, YOU BASTARD!"

With that final scream, Accelerator reversed the Professor's blood flow. Kyousuke's organs violently imploded and his blood vessels were brutally ruptured. Unsatisfied with such a mundane reaction, Accelerator greatly increased the magnitude of the blood's vectors, which resulted in the Professor's entire body bursting open in a shower of gore.

Breathing heavily, the blood-stained Accelerator shakily stood from his kneeling position and pressed the switch on his choker-style electrode, deactivating his powers. Without his Reflection active, the droplets of rain pelted heavily on his bloodied clothes but it did not seem to bother him.

'That's another asshole punished; only a handful remain…including her. But how much time do I have left? Those girls may have a few more days but should I really leave their fate to chance?'

Accelerator leaned against the wrecked vehicle as he contemplated is his next move. There was still plenty of charge left in his electrode and the unquenchable thirst for vengeance remained fresh in his mind. But time was not a luxury that the SISTERS could afford. With each passing hour, they were quickly approaching their premature demise and Hell will freeze over before he'll allow that to happen.

The revelation that he experienced earlier had traumatically shaken his mind and had sent him on a nightlong rampage of vengeance that strayed him from the greater objective. Accelerator cursed himself for allowing it to cloud his judgment. The lives of the clones and those who valued them as well should always have been first and foremost. He could pursue the remaining Core Personal of the Level 6 shift experiment later.

A certain Level 0 had placed a resolve in Accelerator when they fought in Russia and it eventually became the unrelenting drive that gave him the indomitable will to protect those he treasured. And that same resolve had begun burning brightly with his original goal taking precedence over his actions.

The hunt can wait. Right now, acquiring a cure for the deteriorating conditions of the SISTERS is the top priority.

With a slight flick of his wrist, Accelerator's high-tech crutch extended from the casing strapped to his forearm.

Academy City's Strongest Esper hobbled off towards the dark alleys, leaving behind the mess he just made with only a single resolution echoing in his head.

'That Brat, that Bitch, the SISTERS and even The Railgun…I won't just save them from the Darkness. I'll fucking tear its corrupted heart out and free them from its oppressive tyranny, once and for all!'

Well there you go, my first chapter concluded. Now this is near the climax of the story, the next chapters will chronicle the events leading up to this chapter and progress to epilogue. There you will find out why Accelerator is hunting down scientists, how Mikoto got involved and who is this her that Accelerator is referring to. I'll give you one clue though, Accelerator is emotionally conflicted about confronting this person for her involvement. Once again, thank you for reading and I hope to receive positive reviews.
