Vermillion Erika

Japanese name:

エリカ・バーミリオン

She is the head of the occult research lab, of which Tamami, as well as Kozue is technically a member. She is never named and only referred to as "club president (ぶちょう, Buchō)" until the final chapter of the manga. She has a masochistic slant as well, and painfully enjoys Tamami's talent for insults and other unusual tortures.
