~~10 years ago~~

Y/n L/n ran through the playground, giggling and laughing in her f/c tank top and jean shorts, as she went around, looking for someone to play with. The playground was close to empty, except for a small group of kids playing by the swings. She smiled seeing they were girls her age as she skipped over.

"Hi!!" the girl smiled brightly. The other kids turned to look at her, and gasped. She had large demon eyes, that were a bright f/c. The girls screamed pointing to her. "What's wrong with your eyes?!" One girl says.

"They're so creepy!"

"Cover them up!"

One boy came over and started throwing fistful of sands at her. "Exorcise the demon! Exorcise the demon!" he chanted, The other girls joined in doing the same.

The little girl cried out, covering her eyes, as she could feel the sand getting in her eyes. The sand was now stained in her h/l h/c. She hunched over, begging them to stop. "Please.... I'm not a demon!" she cries tears streaming down her cheeks.

Another girl shoves her so she falls over. "Look at that! The demon is crying now!" Y/n got mad as her eyes started to glow. She stood up, tackling the girl, staring directly in her eyes.

"I'M NOT A DEMON!!!!" She screams. The little girl seemed paralyzed as she screams, clutching her head in pain. She starts to thrash as Y/n scrambles off of her. "What did I do?!" Y/n cries now worried.

"MOMMY! THE VILLAIN! IT'S COMING!!" an older woman who was similar to the crying girl rushes over immediately. "What's wrong?!" the boy points to Y/n. "She did something to her!"

The woman glares at Y/n with a burning hatred, as she slaps her across the face. "You little freak! What's wrong with you?!" she tightly grabs her shoulders, shaking her before slapping her over and over.

"Kids! Get away from her!" the mom yells as all the kids run away, still chanting "exorcise the demon!"

Y/n collapses on her knees, sobbing as she buries her face in her hands. Small grains of sand fell out of her hair as she fiercely tried to get them out.

She looked ahead and saw a woman talking to their local hero, Kamui Woods, pointing in her direction. "She did something to my daughter!" The little girl nods. "I...I saw scary things! She is a demon!"

Kamui Woods looks over at the girl, making eye contact for a moment before breaking away. He gives the woman a comforting pat on the back.

"Leave her be." he says, before the small group of kids and pro hero walk away. Her eyes widen as she starts to cry once again.

"He just left me...... He sided with them......he doesn't even know the full story! He didn't see what happened!" she screams.

There was a sudden loud whooshing behind her. She gasped and turned around to see a dark purple warp gate. A man with pale blue shaggy hair, with several hands on his body, including his face, appeared.

Y/n backed up shakily, realizing it was a villain. "What do you want?!" she yells. The man chuckles, crouching down next to her. "I've been watching you for a while. That is some quirk isn't it?"

She is silent, not willing to answer the villain. "W-When you ask for information about someone, it's only proper to give your name first!" she says. He chuckles, sitting down properly next to her.

"You're right. My name is Shigaraki Tomura. I work for the League of Villains. And I understand your pain, Miss Y/n."

Y/n gasps softly. "H-how could you understand?! You're a villain!" she exclaims. "I am going to be a hero someday!" Shigaraki flinched at this, looking at the girl with a more harsh glare.

"Oh? A hero huh? Take a good look at this society. No, what Kamui Woods and that mother just did to you." he says. "He took the mother's side, not even coming over to scold you at the very least."

Y/n visibly flinches, knowing this was true. "Do you really want to become a part of a society, with sorry excuses of heroes like that?" Shigaraki stands up, the warp gate still open as he goes to step in. Before he does though, he turns around to Y/n holding out his hand.

"Come with me, Y/n. Join the League of Villains, and fight with me to destroy this corrupt society!"

The small girl stares at the man's outstretched hand. Everything this man had said to you, felt so right. It seemed to click in your brain all at once. Y/n nods, taking his hand, as the two walk through the warp gate, disappearing from the park.

There was not a sound in the park, except for the gentle breeze, pushing the rusty swing. There was not a single person to be seen in the park. But, poking out from behind a tree, was the shadow of a small boy, who appeared to have been in shock from what he just witnessed.

'What happened to that h/c-haired girl?! She's gone! Did that villain snatch her up?! Why was she with him?!'

So many thoughts were racing through his head, but all he could do was walk away, hoping that she was alright.

~~Meanwhile~~

Shigaraki and Y/n appear in the small bar, where stood the warp gate, and now the young girl and leader of the organization. "Welcome home, Y/n." he says grinning wickedly. Y/n walks around, still a little timid in the new setting.

"T-This is where I'm going to live now?" she asks shakily. Shigaraki nods. "With your quirk, we'll be able to destroy those bastards of society, especially him!"

Shigaraki points to a small poster with the Symbol of Peace, All Might. He yelled out slamming his fist on the table. He'd been trying to find a way to destroy him. Y/n gently put a hand on Shigaraki's fist for comfort. "It's okay... Nii-san..."

Shigarak's eyes widen hearing her call him this. "Nii-san?" he repeats. Y/n nods. "You're like a big brother to me. And as your little sister, I need to help you get rid of the bad man, right?" she grins.

"Of course." Shigarak's grin from before appears again. "Sounds good to me."
