Sadi has long unkempt orange hair that covers her eyes. She resembles a dominatrix in design.
She dresses in a very skimpy red (hot pink in the anime) devil-themed outfit. Her outfit covers only the top half of her exposed breasts with laces that hang down that are also featured around her waist. She has long sleeves that slope into stylized rips. Around her neck, she wears a scarf-like cape that is white on the outside and pale pink on the inside. She carries around a pitchfork and wears a headpiece that resembles horns. She wears candle-shaped earrings and high-heeled shoes that come to a curved tip decorated with spikes.
