Study

You decide to study about science, biology and human behavior, due to the encouragement of your father, which as a result causes you to have a level of intellect on pair with some of the smartest people in the world. However due to this you haven't had as much time to train your quirk, but do to your intellect you are able to work around it somewhat.(medium control, high intellect, low body) Afterwards you ,despite your young age, receive a internship at one of the best quirk study labs in the world, besides your fathers obviously, known as Hosu labs in Hosu city, Japan. You turn the offer down due to Hosu labs rivalry with your father and due to the fact they have tried several underhand tactics to get your fathers research, which all failed. However you do say that if given time to study more and grow you might consider it. However this is a lie. You said that only to appease them due to the reputation of the head scientist of Hosu being that of someone who does not like failure or being said no to.
