Saeko Kageyama

Saeko Kageyama (影山 冴子) is the calmest of the Lucky Clover, who works as the proprietor of the Clover Bar. She is the alter-ego of Lobster Orphnoch (ロブスターオルフェノク)

History
Her calling card to her victim is to send them a bottle of wine, which turns out to be their final drink. She enjoys seeing others suffer and comforts them in a somewhat disturbing fashion. Itsuro Takuma always wanted to impress her and will do anything under her orders. She also once had the possession of the Kaixa gear along with Takuma who uses the Faiz Gear and uses it once to hunt the Orphnoch renegades. Upon learning of the Orphnoch breakdown and the Orphnoch King's power, Saeko was intent to survive. Saeko succeeded by allowing the Arch Orphnoch to completely evolve her, removing all traces of her humanity, and thus became his caretaker after he was defeated by Faiz.
