Olive has long chartreuse yellow hair, emerald green eyes and raceless white skin. She wears a light olive colour dress with white cuffs and a dark brown jumper above it. She also wears black and brown striped stockings with brown boots and black gloves. She sports out a brown beret on top of her head. She has orange blush on her cheeks and has 2 pairs of wings, though her wings aren't very obvious on her character art.
In her character art, she is seen wielding a gladius sword with an olive green hilt and light olive tinted blade. The sword is intervined with an olive branch.
