You were born into the world of heroes and villains powerless. You weren't given the ability to fly, to produce fire, or ice. You were given absolutely nothing. Despite all this you longed to be a hero, after all who wouldn't. The heroes of society were admired and wealthy. You had nothing. To combat the bad hand you were given in life you started training at a very young age, you learned all the marital arts you possible could handle and worked your ass off to obtain a body even heroes would envy. You found peace in the violence, a small part of you even liked it. You studied psychology and criminal behavior hoping that maybe just maybe you could pass an entrance exam to one of the hero schools. Not only did you manage to compete with your fellow competitors, but you actually managed to score higher than a few of them. The letter you got in the mail shattered your heart.
"Congratulations on placing well during the exam. You have great skill and a heroes heart! Unfortunately, due to your status as quirkless you are not a right fit for our incoming class. Your skills would be better suited for the police force! If you would like our academy would be more than happy to write a glowing recommendation to ensure your..."
It droned on and on and on. You were left bitter and angry, but what could you do? You had tried your hardest and had even done fairly well, but it wasn't enough for those bastards. You went to normal highschool and focused on training your mind and body for the police academy. You eventually found yourself becoming restless and would find yourself wandering the streets at night hoping to find something, anything to take your mind off your misery.
You eventually stumbled across a man trying to steal a womans purse. She looked as if she was made of glass and the man had sharp claws and teeth. Mutant class quirks, you thought to yourself. Silently you creep around the man and bring down your fists on the back of his neck. "Run" you said quietly to the woman. She noded and ran away. The man struggled back to his feet in a daze. You smiled and kicked his abdomen hard. He fell to his back groaning in pain. Looking at him lying on the ground broken and suffering filled you with a sense of satisfaction unlike anything you had ever felt before. You droped into a squat by the man and grabed one of his clawed fingers, "If I ever catch you hurting anyone else around here again I will break the other nine." He whimpered and tried to run away fearing what will happen next. You snaped his finger back and kicked him into the street smiling with satisfaction. You definitely could never become a hero, but maybe you could be some sort of vigilante.
You continued to patrol the streets stopping petty crimes and enacting your punishments growing increasingly sadistic. Eventually the crime dwindled down to next to nothing, so you decided to relocate. You chose an apartment that was near the location of several stabbings. You rationalized the move to your parents saying that it was near your highschool and that taking care of an apartment would be a good lesson in responsibility. Your parents had doted on you since you were a child, hoping it would make up for the fact that had created you without a quirk. They accepted, and paid for you apartment in full. You started tracking the murderous stabbing incidents in your free time. You figured out that the culprit was a sadistic schoolgirl who evaded capture using a strange blood type quirk by piecing together many eyewitness accounts. You decided to head out to the central point of this girls killing grounds making yourself out as bait.
You walked in your school uniform with you head held down low and made yourself seem like an easy target. Your heart skipped a beat when you heard a female voice call out to you.
"Hey are you lost?" She said sweetly "I'm kinda lost. Wanna be friends and figure out how to get home together?" You eyed her up and down. She would have looked like an average school girl had you not been on guard. She was pretty, but her hair was a little disheveled and her uniform was dirty. She looked like she had been roughing it for a while. You noticed that her tights were ripped and tearing in several places. At a glance she looked like any other normal schoolgirl, but you knew the truth. This girl was a murderer.
"It would be nice to walk with someone, yeah. I wouldn't mind being your friend." You walked with her for a little making idle small talk. You couldnt help, but wonder what turned this girl into a murderer. She seemed so normal, kind even. She stopped and turned to face you.
"Hey we are really good friends now right?" She asked smiling in a way that unsettled you. You nodded and then you saw a flash of silver. You moved just in time to avoid a knife to your neck. You felt a smile creep across your face as adrenaline flushes your system. She fell into a predatory stance and eyed you warily. Your smile clearly put her on guard. She lunged at you again moving incredibly fast, but you were faster. You caught her arm and forced her to drop the knife. She cried out in pain as you twist her arm. Then she smiled and bit you. You tore your hand out her mouth in shock as she began to transform. She started to take on your appearance and lunged at you. You quickly punch her in the stomach and she crumples to the ground laughing.
"So, what's your quirk, enhanced reflexes? Mind reading? How did you know I was going to attack you. Cmon you can tell me! We are friends aren't we?" She said whilst wearing my face.
"I don't have one"
She looked surprised, "What do you mean you don't have one?" She stifled a laugh, "OMG are you actually quirkless? With a body like this I figured you were some bigshot hero student." She flexed your muscles mockingly as she got back to her feet.
She went for a low kick, but you quickly moved out of her reach. You failed to see that she had retrieved her knife during the maneuver. You barely managed to move out her knifes swing and it managed to graze your cheek. The sight of your blood made her blush and she went in for another strike. You grabed her wrist mid swing and squeezed tightly. Forcing her to drop the knife. She tried to scratch you with her fingers, but you kneed her in the stomach hard and shoved her to the ground. On impact with the ground her quirk dissolves. She is pinned underneath you breathing hard, naked and blushing. You squeeze her wrists hard again and she squeals in pain and delight. You are shocked by how good it feels to hurt this girl. It doesn't help that she seemed to enjoy it too. You felt a wet sensation seep through your pant leg that was near her crotch. You noticed the growing bulge in your pants and couldn't help but wonder how good it would feel to fuck this villain. She had hurt so many people, maybe it would be divine justice to hurt her too. You held her close feeling her breasts press against your chest. You whisper in her ear while wearing a sadistic smile, "Hey, we are friends right?"
