About 1 year had passed after an incident. you had fallen in battle after that explosion, his fellow heroes, including his friend Katsuki, took him for dead...no one survives that explosion...do they?

They didn't know why...but Katsuki was in front of you. You were alive, but...you had a different look...you acted different, more determined and ruthless...Katsuki didn't recognize you. I only saw a villain

Katsuki: Who are you?...he asks with a Stoic look to hide his anger and pain at seeing you act like the bad guy/girl
