Cathy is a fairly tall woman. She has shoulder-length blonde dyed pink hair with bangs and green eyes. She seems to be wearing red lipstick and has long lashes. Her outfit consists of a rectangular hat, a black short-sleeved blazer with a red tie, a mini pencil skirt with a slit on the side, red gloves with her right hand having a ring, and thigh-high heeled boots. She is almost always seen with her small red whip.

She didn't have her hair dyed pink prior to the events in the game, as shown in Episode 0.
