Shigaraki was in an intense battle with some of the pro heroes, he told you to hide because he doesn't want his daughter to get hurt. So you hide behind some trash cans, but All might sees you and walks to you, he kneels down to get to your eye level, he says,

All might: Hey little girl, where's your parents? he said in a soft tone

Hawks: that's shigarakis kid, you shouldn't mess with her, shigaraki will get more agitated then he already is.
