Beatrice

The Golden Witch and Endless Witch. She is affectionately referred to as "Beato" (ベアト). 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 Kinzo ten tons of gold and served under him as the alchemic advisor to the Ushiromiya family.

She is one of the personalites of Yasu and was made as the ideal girl for Battler to fall in love with after Shannon's feelings were made to be directed at George instead of Battler
