Lady Jaguara is the tertiary villains of Wolf's Rain, 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 was rejected by him for her younger sister, something which she never forgave Lady Hamona for. Instead of accepting her sister's death of Paradise sickness as her fault, Jaguara blamed Darcia for everything that happened between her and Hamona.
She once had Hige brainwashed to be her lap dog and the alpha of the group of wolves used for her campaign to eliminate the remaining wolves. She saw wolves as a threat to her plans to open the Nobles "Paradise".
