Nafra is a demon who is always seen with her gray robe with a hood. She has rounded eyes, and (although popularly nicknamed Mouthless Nafra) she has a wide mouth that is usually curved. She shrouds the edge of her face with the hood of her cloak, so that only her eyes and mouth can be seen. Underneath the cloak, she wears a typical student council uniform with its complete set. The cloak gives her the ability to change her height and she often presents herself as short when wearing it. Her actual appearance has curly shoulder-length hair with a flower hair decoration and facial features similar to Iruma.
