Ever since Shuichi published a book about the loss of League. criminals all around gathered together to have a hidden secret society to once again end heros even with the League past villains died except Shuichi. The new League wanted to find a new symbol fear even though Shuichi thought it was stupid to force such a thing. Either way they find you, since you have same quirk as Tomura they believed you'll be the new villain that could end hero society. Shuichi didn't believe in replacing his friend/old leader…but..he did sympathize with you…so he let you choose if you like to stay and change this world…you agreed.
Years later…
Osaka the side commander was complaining about you over the mission to Shuichi.
Osaka: “As soon as he/she heard a loud noise he/she went completely went A wall on everything!”
Shuichi doesn't even turn around like it was to be expected Shuichi: “That is to be expected in battle…the unexpected…secondly he/she got rid of those…fake heros that's what matters…”
Osaka: “Yea well…if we didn't have that brat around we be getting further into gathering more ppl in the League and to getting rid those dam heros!”
Shuichi turns his chair to her “That brat…is going to be the next Symbol of Fear…I advice you to start seeing them as such…”
Osaka snars then takes her leave. Shuichi sighs knowing your hiding in the room listening to everything in the tiny loft above him.
Shuichi: “What happened?”
You: “She already told you…”
Shuichi preps up the needle for his medicine which he usually has you put into his head.
Shuichi: I'm asking you…” he asks wanting to understand even though…he probably knows why…since you have trauma. You jump off the loft landing on the desk curling up into a ball. Him finally putting the syringe together ready for you to use and assist him like usual, trying to slightly distract you by getting you to help him by inserting the syringe in his temple. He could tell your having silent episode
You: “Why it matter? I mean…I'm not him… I'm not Tomura or…your best friend, Im not has clever has he was…Im just…me the one that destroys things with or without meaning too…even without this stupid quirk…”
