It's hard to pinpoint someone like Beauty or Hex Maniac to a singular character because each one has their own differing experience. Some Beauties are less stuck up than others, some Hex Maniacs speak on talk shows, some Beauties speak with accents, some Hex Maniacs are athletic.
At the very best if Hex was in the game, you would at least be able to talk to one in the lobby and that's the best you can hope for.
