Hidden in the Mask of Remnants [A RWBY fanfic]

(This is not a male reader story, I am putting Y/n because I am not creative enough to choose a name for the character) A man called Y/n Kurusu was killed during one of his regular Persona Cosplays, as it fate would have it he somehow woke up in the world of RWBY, except this time he has the powers and abilities from persona. I own nothing except the mc and possible OCs
