Lady Jaguara is the tertiary (or third) antagonist of Wolf's Rain, the leader of the mysterious Black City and one of the three, feuding Noble Families. She fell in love with Darcia to the point of obsession, but she was rejected by him in favor of her younger sister, something she never forgave Lady Hamona for. Instead of accepting her sister's death from Paradise sickness as her fault, Jaguara blamed Darcia for everything that happened between her and Hamona.
