Dead Master stands out with her striking neon green eyes and straight-cut black hair. She's got a full Gothic lolita aesthetic going—black dress hitting mid-thigh with a white ribbon at the waist, matching bolero jacket, black leggings, and black pumps. Black gauntlets cover her hands. The most distinctive features are the pair of long horns on her head (shaped kind of like vertebrae with triple-pointed tips) and a set of wings positioned low on her back.
In combat, she wields the Dead Scythe and often fights with chains as her weapons. Fans often note that she serves as the "other self" of Yomi Takanashi—essentially her alternate world counterpart.
