Erza is a slender girl with pale skin and long red hair tied in a high ponytail, flowing down her back almost to her waist. She has two white horns on her head, giving her a unique appearance. Her bangs cover her right eye. There is a blue bracelet on her left arm.
Her outfit consists of a white bandage top wrapped around her chest and back, leaving her stomach and shoulders exposed. A white belt is tied at her waist, supporting loose-fitting maroon pants with yellow flame patterns at the bottom. The pants are wide and reach down to her ankles. Erza is barefoot. From the back, it is clear that her hair is very thick and long, and the pants have large back pockets.
