Sucrose, of medium height, boasts fair skin, amber eyes, and chin-length light green hair, extending to her hips at the back. She wears dark brown round spectacles and has pointed light green animal ears she conceals with her hair, their origin a mystery she investigates. Her hair is tied into a low ponytail. She dons thick white gloves, dark brown-rimmed glasses, a blue corset with a crest, white boots, black thigh-highs with garters, and a white and blue beret.
