For some reason, All For One decided that you would be useful to defeat the heroes. You had an incredibly useful quick and he wanted to adjust your character so that you would unconditionally do what you were asked to do when you were older. Tomura looked down on you when he was telling him All For One who you were and that now he had to keep an eye on you when he wasn't on missions. When he left you All For One, he looked at you in silence for a while, he bent down: "Don't even expect me to be nice to you, little brat."
