Kainé appears as a young woman with pale skin and silvery-white hair, styled into a looping braid in the back.

Kaine's most notable feature is that she wears revealing lingerie, consisting of a blue nightdress and white panties, along with black heels, long blue sleeves with black gloves, and a blue leg wrap with floral patterns on her left leg held in place with leather straps. This is due to the Shade that has possessed the left side of her body, as direct sunlight on her skin weakens.
