Kasumi is a slender, physically-fit, and petite young woman. She was designed to appear "soft" (based on the idea that Dead or Alive is softer in concept compared to Ninja Gaiden, thus making her symbolic of the series) so she was originally designed with a childlike and youthful appearance, with fair skin, a round face, small facial features and wide, amber eyes. For Dead or Alive 5, her design was slightly altered to appear more mature, so she now has an oval-shaped face and narrowed eyes.
