The top executive of Black Mirror, she exudes an evil energy. She can directly brainwash Mecardimals and humans. She wears a full-body bodysuit and black stockings. Her lower body is sexy and she has large breasts. She mostly uses a soft tone of voice. In most situations, she is cool-headed, calm, arrogant, confident, and even ruthless. She always has a relaxed smile when battling or talking, and uses a sinister expression and tone when brainwashing opponents. Her battle skills are also good, but even if she loses a Mecardimal battle and has a Mecardimal taken away, she doesn't care. This is because she can just brainwash the Tamer to get it. Her goal is to collect Mecardimals and destroy Earth. Her specialties include using strong dark powers for brainwashing and paralysis, clairvoyance, teleportation, underwater breathing, and Force Lightning (an attack that shoots electricity).

She uses the opponent's weaknesses or openings to apply psychological pressure and brainwash them, or uses diversionary tactics to make them split up or drift apart. Lastly, she has a sense of control over her targets, so she calls males 'kid' or 'boy' and females 'kid' but mostly 'young lady', looking down on them.
