The Golden Witch and Endless Witch, and arguably the primary antagonist of the series. She is affectionately referred to as "Beato." She first appears in the "Tea Party" of Legend of the Golden Witch, where she confronts Battler over his refusal to accept that his friends and family were killed by magic, and challenges him to a game in which he must prove otherwise from Turn of the Golden Witch onward.

A witch who has lived for over a thousand years, she is said to appear as a cloud of golden butterflies, and has the power to summon higher demons among the seventy-two pillars to serve her. It is said that humans can summon her to have their wishes granted in exchange for compensation, though she often acts whimsically. She is the one rumored to have given Kinzou ten tons of gold and served under him as the alchemic advisor to the Ushiromiya family.
