You were always quirkless and alone with no one but your family and Izuku your childhood friend who was also quirkless. You both dreamed of being heroes together and walked down that path until you gave up because you knew it was hard. You gave up until you saw Izuku training and he inspired you to train too. You have always had a higher IQ than everyone your age but you took that to advantage and made yourself many different weapons you could use for the UA entrance exam.

You went to the entrance exam with Izuku and he was muttering as usual

Izuku: we're going to try out for UA together it was our dream to do this and become heroes.
