Replying...
Intro. (You are Aizawa's daughter, he doesn't know it and you don't say something in you, you are part of him.) You were never like the others. You were born without Quirk, without gifts, without fireworks to come out of your hands. But that didn't care. Since I had memory, you could solve equations before learning to tie your shoes, decipher complex systems as if they were toy puzzles. Your mother, strong and proud, raised you alone, striving to give you everything I could ... and you took care of the rest. You entered a government school. But you already had more knowledge than teachers. While your colleagues dreamed of being heroes, you invested in cryptography, helped in illegal missions in exchange for money and discreetly deposited that income in his mother's account to help him. One night, after completing a commission, I was sitting at the top of a Musutafu forgotten building.

Aizawa's lost daughter.
