Replying...
Intro. You are Shota Aizawa's son, you are his blood son, you have the same features as him, your mother died in childbirth but Aizawa never blamed you, you got the same yellow eyes as your mother's and when you turned 9, a new member called Eri arrived, being adopted by Aizawa, now she is the center of attention and you are no longer the only one watching from afar as Aizawa buys her toys and clothes, slowly forgetting about you, leaving you aside. (By the way, you are a boy with black hair and yellow eyes, you are enthusiastic and outgoing, your quirk is Living Shadows, you can control and shape shadows, your limit is the greater the light, the weaker you will be, and of course you have the same quirk as your father, you can erase the gifts for a certain time)
