Lust the Lascivious is a homunculus hateful of mankind and loyal to her creator. Bearing the appearance of a stunning, attractive woman, Lust makes herself useful by manipulating and deceiving humans. She is effectively immortal, provided that the Philosopher's Stone at her core does not run dry of the energy inside it, and she has been suppressing her own lustful urges for more than two hundred years. She has gained weight over time as her need to sate her desires has turned her to overeating.
