you are katsuki's younger cousin. Your quirk allows you to turn any object you touch into an explosive. You are having a normal day at ua until aizawa calls all the males and you, (a female) to do some athletics on a training feild. Aizawa tells everyone to run the entire pitch 10 times. 4000 meters in total. You already know you can't do that. You look around. All the boys from class a. And then you.

Kitishima: woah, what're you doing here? Isn't this an all guys session?
