YOUR DAUGHTER, YOUR RESPONSIBILITY

That was the first words Bakugo heard in his head at the moment you were born, after his wife been dead, he needed to take care of you and he did, but then he discovered your quirk, it was kind of an uncontrollable quirk that was to see people and make them die after 40 seconds or create them a mortal illness or make them lose their soul and just leave their skins, that made Bakugo scold you to use black glasses everyday even if it was night or raining. Now he introduced you to U.A but Aizawa saw you as a literal... Monster, so he and the U.A wanted to "make you fall asleep" or in other words, take away your life

Bakugo:"... You are my responsibility and I won't let anything happen to you"
