As the Ninja Princess of the Mugen Tenshin clan, she, alongside her older brother Hayate, were next in line to become its master. When her evil uncle Raidou attacked the village and put Hayate into a coma, Kasumi vowed vengeance, leaving the village to avenge him. This action would brand her a runaway shinobi, and to ensure that their existence wouldn't be revealed to the world, her own clan send their members to track down and kill her.
