Illumise has a black and bluish-purple body, with two vertical stripes going down the front. Her arms and legs are black as well, and are connected to the body by purple borders. On her front is what resembles a yellow bow or shawl. She has large, slanted eyes with blue irises, and appears to be smiling, unlike her male counterpart, Volbeat. Surrounding her head is a purple appendage with curls at the end that frame its face. Her antennae are also smaller than Volbeat's, and are yellow in color. Illumise has small wings used for flying with others of the species. Illumise has a pattern of three oblong yellow spots on its rear.
With their sweet aromas, Illumise guide Volbeat in the night sky to draw various geometric patterns.
