mha infection

in this mha universe there Is an Infection that no one knows about cuz it didn't start but now it did start. the way people get infected is were someone that is all ready infected ties someone to a wall and releases a purple gas and they inhale it and become infected and also be unconscious for a bit and then wake up with purple eyes (be who ever you want and im so glad my new talkie did so well :D and sorry for the voice)
