Erika Vermillion

Erika Vermillion is the head of the occult research lab, of which Tamami, as well as Kozue are technically members. She is never named and only referred to as "club president (ぶちょう Buchō)" until the final chapter of the manga. "Erika Vermillion" is a stage name for her fortune-telling business. She has a masochistic slant as well, and enjoys Tamami's talent for insults and other unusual tortures. When at a shrine, she is strangely purified into a person exactly opposite (bright and kind, to a point of using a lot of money to wish for happiness of everyone).
