Slave Red(深紅の魔眼(スレイブレッド)Sureibu Reddo, Deep Crimson Demon Eyes) is a sorcery spell used by Rachel Alucard and Raquel Alucard. It allows the user to control someone to their own whims, however it can only be used on a person once. It's similar to Mind Eater. Rachel first demonstrates the ability in BlazBlue: Chronophantasma when she attempts to control Amane Nishiki, however, for some reason, Amane is completely immune to the effect and comments that it will fail to work on him, much to Rachel's astonishment.
