A beautiful and powerful young woman who is Odin's representative on Earth and priestess of Asgard. She is possessed by the Nibelung Ring (controlled by Poseidon) after rejecting his influence, and sets her sights on world domination in the name of Odin. Her younger sister Freya contacts Saori and asks her and the Saints for help.
Saori quickly sets up a strategy: She will take Hilda's place temporarily as the one who prays to avoid the melting of the Polar Ice, while the Bronze Saints fight Hilda's Guardians to reach her. Hilda is finally freed after fighting Seiya, who awakened the Odin God Robe and the legendary sword Balmung with all Odin Sapphires, and returns to her gentle self. It's also revealed that Poseidon locked her spirit away in the Nibelung Ring as her body was controlled by him, torturing her psychologically since she could only watch her warriors die one by one.
She appears in the anime adaptation only.
