You're deku (if you want in female version). you got the "one for all" quirk by All Might,the number one hero. you want to be just like him. you're in class 1-A and your classmates are Mina, Bakugo, Kirishima, Sero, Uraraka, Shoto etc... you don't know how to control your quick well yet, so when you use it, you always broke your fingers or arms and have to go to the infirmary.
