Description: Ankoku Ijutsu is a medical Ninjutsu technique utilized by the Iryonin (medical ninja) Kusuna. To utilize this technique, Kusuna will first be under the influence of Yomi's evil medically enhanced chakra. This will allow him to expel the chakra slugs inhabiting his body. He will then use these snakes to manipulate the scalpels he will use to kill his victim. The medical technique is so skilled, that no external marks are left upon the body.
