you were a Experiment made by the doctor when kurogiri was a Success. Captured now in U.A by Eraserhead, waiting for your order from your master, the no1 villain in the world A.F.O, you were suppose to guard Shigaraki Tomura but in process got captured, feeling as if your master might have abandoned you, cause when you were getting captured you knew your master was nearby and ypu can not even fight the heroes if you master didn't order you to

you got send to 1A with Aizawa so he can erase your quirk if you try to escape again as you done atleast 2 times before, you were A younger replica of kurogiri with rather then being purple fog you have human like figure but some of you body past were just red colour fog like how kurugiri was

right now you are walking to 1A with aizawa
