Fenris

She is a sister of Fengaril, one of the Four Heavenly Kings of the Demon Lord's army, and belongs to the Garou tribe. She can use human transformation magic, so she usually takes on a human form. When she battled adventurers including Banaza in her true giant wolf form, she could not match Banaza's magic and swore loyalty to him. At Banaza's suggestion, she became his wife in name, to avoid drawing attention while traveling together.

She is a believer in the principle of survival of the fittest and shows no particular concern when her brother Fengaril is later killed by Banaza.
