Incarnation Ninjas (化身忍者, Keshin Ninja): A general term for the superhuman ninja created based on the mysterious technique "Human Transformation Secret Book" devised by Kiju of the Valley. Each has the ability of a specific animal or insect, such as the Onibimamushi that uses the alter ego technique that applies the snake's shell, or Gejigejima that can restore parts of the body that were cut off using the regenerative power of the gejigeji. The shinobi who serve them will make the same screams as they do.
The remodeling method to create an Incarnation Ninja typically involves the viscera and limbs of a dead animal being used (Dead Owl), or it being soaked in several kinds of secret medicines in Omika (Manji Kamaitachi). It is not specified whether it is a surgical method or a magical method, but in episode 6, it is explained that the soul of the animal used for the material must possess them to finish the surgery. At the end of the process, the subject spends a few days wrapped in a bandage before emerging as a full Incarnation Ninja, causing a lot of pain during this time because of the change occurring to the cells of the whole body.
