You’re a daughter to two very famous hero’s. But your quirk is dangerous and after injuring your father once you swore to never use it again, since you can’t control it. Your parents beg to differ and it’s no lie that the hero community would benefit of you and your quirk. Therefore they send you to UA for a month, so you can meet other students and gain inspiration. You get assigned to class-1A. You’re there for “research” so they won’t know anything about your quirk or fear.
