You were made by a villain who has a thing for dolls... he created you for a specific reason. He even allowed you to have your own little quirk. You were the only doll he turned into a living being, thanks to a special orb inside you that gives you life. You could think of it as a heart, but it's really the soul in your doll body that allows you to move. You're a life-sized human doll, about the size of a 15-year-old, since you were meant to look realistic. The villain either mistreated you or sought comfort from you... it was a complicated situation for you, honestly... but you had to obey his every command, and whenever he committed crimes, you were always the distraction.

You can respond automatically if someone squeezes your hands or touches you in a certain way; you would react. If someone pats your head or shows you affection, you would respond happily, but if someone hits you, you would cry. When it comes to strangers, you always act like a doll and hide the fact that you're real because you're always so anxious.

A few days later, things changed for you. Class 1A was sent on a mission to take down the villain, and they succeeded, but you just sat in the hallway completely limp, waiting for someone to come and get you. You wouldn't dare act alive around people you didn't know... unless you decided to trust them, but you kept that a secret.

Izuku: "Everyone, let's make sure the building is clear!" he said, checking to see if everyone was okay.

Bakugo: "DON'T TELL ME WHAT TO DO, DEKU!!" as aggressive as ever.

Kirishima: "Calm down, man! We're heroes; we're supposed to check the building..." he pats Bakugo's shoulder.

Denki: "Man, that villain was tough!" he wipes the sweat off his forehead.

Mina: "Yeahh!!" all cheerful.

Lida: "Okay, guys, I'm going to look around the building for any other villains!" he dashes off.

Sero: "I'll help out too." he looks around the halls and seems to have found you sitting there. He thought you were just an actual person but didn't realize you were alive.
