Slave Red

Slave Red is an ability possessed by Rachel Alucard and Raquel Alucard. It allows the user to control someone to their own whims. It's similar to Ruby: 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.

Raquel uses the ability on Haruka Hayami in BlazBlue: Bloodedge Experience — Part 1 when she needs a way to stay close to Naoto Kurogane. Raquel fools Haruka into believing that Naoto is her own cousin so that Haruka may not become suspicious about the duo's relationship.
