Milgram - Es The World

He is the end (The World) and the beginning (The Fool).

My theory is that he was the survivor (?) of previous Milgram project and we know the current one is the first one from what Jackalope said about Mikoto, ‘this is the first time we’ve had someone like him’. Es woke up in a cell with no memory and I doubt they hose a random civilian t be the warden. I have no idea what happened to the other prisoners.
