The reigning monarch of the Mazone, she is determined to lead her people to make Earth their new home following the destruction of their home planet. As cruel as she is beautiful, Lafresia was once a wise and kind ruler, but the situation of her people leads her to change for the worse as the series progresses. She initially did not see Harlock as a major threat and even saved his life early on, but would later come to regret it. Faced with a plot to kidnap Mayu Oyama as a means to draw out Harlock, Lafresia resists at first, considering such a tactic as unethical at best, but she later gives in when faced with the threat of the Arcadia to the Mazone, which later causes discord among the alien invaders.

During a final showdown against Harlock, it is eventually discovered that Lafresia is not Mazone, but human. After defeating her in their duel, Harlock allows Lafresia to leave Earth with her people and settle elsewhere.
