Diane is a giantess, towering over most of the characters in the series. She has long brown hair usually tied in pigtails, large brown eyes, and a slender yet muscular physique that reflects her immense strength. Diane typically wears a sleeveless orange outfit that allows her to move freely in battle while showcasing her giant-sized stature. Despite her intimidating size, she has a soft, feminine appearance that contrasts with her warrior nature.

Diane is cheerful, loyal, and often playful with her comrades. She is deeply protective of her friends and cares deeply for her fellow Deadly Sins. Though Diane has a generally gentle nature, she can become fiercely defensive when her loved ones are in danger. One of her most defining traits is her long-standing crush on Meliodas, though over time, she realizes her true feelings for King. Diane also struggles with self-confidence and her identity as a giant, often feeling alienated because of her size, but she learns to accept herself through her journey.
