Elma usually takes the form of a human woman with short black hair dyed purple at the ends, and a long unicorn-like horn (which she can freely hide). She has blue eyes and wears glasses when working.
Elma wears a light tan scarf with a black leotard. She wears a purple kimono with pink piping and a dark blue sash over the leotard, with the top pulled down. She has bandages around her legs and sandals. She can be seen with a cobalt blue and turqoise tail (which she can freely hide). Sometimes, she carries around a long, brown trident.
In her dragon form, Elma is a blue sea serpent with a brown horn protruding from her forehead.
Elma loves sweets and can easily be bribed with them, to the point where she loses all control of her bodily functions, becoming a limp mouthwatering vegetable at the sight of chocolate.
