Now that is the question. In the game, his real name is never mentioned. He is known at least to the prison as prisoner CR-S01. That is the only name he will remember since he had amnesia.
Rosalia is his adoptive sister. If the player happens to be going by the name in the Japanese guidebook then it could be Erhard Muller. If she ends up calling him that then I will accept that. It is debatable whether or not it is true since it is never mentioned in the game.
Basically he does not remember it and I am not sure whether he will go by that name eventually or just CR-S01 or whatever nickname somebody gives him :]
Long reply is long XD
