She has medium-length brown hair which is tied into two pony tails. She has purple eyes. She wears a sleeveless, orange mini dress with a hole by her chest, exposing her cleavage. The mini dress's buttons appear to be metal balls. She wears mini black shorts underneath her dress. She wears teal gauntlets with metal balls strewn about. She has a tattoo of a serpent on her left leg. She wears brown boots reinforced with steel and tied with yellow ribbons.


Diane retains her personality from the The Seven Deadly Sins series.

Diane is a friendly person who holds high regard for her friends. True to her namesake as the Sin of Envy, her strong feelings for Meliodas make her become jealous whenever he interacts in a perverted fashion with other women. She is fierce in battle and selfless when it comes to saving lives. She hates to fight and hates being lonely.
