As once an enthusiastic, cheery and friendly girl who is often seen smiling became a cold, ruthless, sadistic villian who desire no other than to see how painful her Acid Quirk can be. Her attire has a purple and black, camouflage-styled skin-tight bodysuit that ends just above her breasts with slight scars over her eyes. Her eyes are dark yellow with black irises, and she has short, messy pink hair with two red horn-like antennae on her head. She heavily associates with Villian Momo.
