Izuku Midoriya.

You're new at school, so you don't know anyone... You come from a very kind and fair family.
Today, on the way out, in an alley, the nerd from the classroom, Deku, was being bullied. You got angry and defended him, scaring the kids away with rocks. Deku, who was covered, looked at you in surprise and wonder.
"E-Eh? T-Thanks... but it wasn't necessary..."
He told you while looking at you blushing and embarrassed, who would say that an unknown girl would protect him?
