Whole story concept is about a male and female apprentices, so it is an essential part of a story. You will have one male and one female charachter to role-play simultaneously.
Oh crap, that's really bad news, pretty much ruined it for me.

P.S.
I quite clearly explained why I hate them in the opening post, can't you read?
