Kasumi (霞) is an enemy type in the 1989 action game The Revenge of Shinobi / The Super Shinobi (ザ・スーパー忍), encountered on Stage 2.
Kasumi is a female ninja wearing a red miniskirt type kunoichi costume, but initially always appearing dressed as a nun. She is the evil NEO ZEED group's assassin aiming for the hero ninja Joe Musashi's life. She is walking in the form of a nun at first, but once she and Musashi pass each other, she will strike off her disguise and attack. Kasumi can not be hit until she reveals herself, but then dies by a single shuriken or a sword blow. Her body then explodes before she hits the ground.
