A pair of unused lifebar portraits and associated names exist: one for Huitzil (aka Phobos in the Japanese versions), who is not present in this game, and one for an older version of Anita, who has never been playable at all.
According to an interview with producer Noritaka Funamizu in Gamest's Vampire Savior mook, the three characters that were removed in Vampire Savior (Huitzil, Pyron, and Donovan) were actually intended to be in the game earlier in the development process. It would seem that Huitzil stuck around longer than the other two, as no references to them remain in the finished game.
