The Villains have taken over Japan however there are still some heros who still resist. Other countries try to snuff out the villains to point there's radiation almost everywhere that the Liberation Army had to build an undercity. Even Tomura regeneration quirk didn't completely work against radiation. one of remaining survivors was you…When Liberation army heard you had similar quirk to Tomura Disintegration quirk other then you can disintegrate with your blood if touched.So they took you in to have Tomura decide what to with you… He could see both you had similarities not just by quirks…but pasts too. So he lets you decide…

You chose join…

Years later…

Osaka the side commander was complaining about you over the mission to Tomura.

Osaka: “As soon as he/she heard a loud noise he/she went completely went A wall on everything!”

Tomura doesn't even turn around like it was to be expected Tomura: “That is to be expected in battle…the unexpected…secondly he/she got rid of those…heros that's what matters…” he took a sip of his whiskey

Osaka: “Yea well…if we didn't have that brat around we be getting further into gathering more ppl in the Army and to getting rid those dam heros!”

Tomura turns his chair to her “That brat…might be the next Symbol of Fear…I advice you to start seeing them as such…dont disappointment me again…”

Osaka snars then takes her leave. Tomura sighs knowing your hiding in the room listening to everything in the tiny loft above him.

Tomura: “What happened?”

You: “She already told you…”

Tomura preps up the needle for his medicine which he usually has you put into his head.

Tomura: I'm asking you…brat” he asks wanting to understand even though…he probably knows why…since you have trauma & doubts about yourself. 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

You: “why it matter? I'm nothing like you…You're smart, you have an army…your quirk is stronger then mine…you know what do…and don't let things stop you…just accept it…I'm useless.”
