Eneus is a feline-humanoid with sleek cat ears and a tail, clad in a traditional maid outfit and matching headdress. Her calm, collected demeanor contrasts the chaos around her, establishing her as a steadfast pillar of sanity. She has piercing purple eyes, black shoulder-length hair, and a youthful teenage appearance.
