Lucy is a gloomy, cynical, deadpan, and mysterious goth girl who is almost always seen with a stoic frown. She is interested in occultism.

Lucy has very pale gray skin and long black hair, with bangs long enough to cover her eyes. She is very thin, and a bit smaller than Lincoln. Dressing in black and white, she wears a black dress over a tank top with black and white stripes, matching black and white striped sleeves and stockings, and black shoes.
