Dead Demon Consuming Seal

This seal invokes the powers of the death god (shinigami). Once called upon, the death god hovers behind the user and wraps its left arm with a rosary, which causes a cursed seal to appear on it. The soul of the summoner is also seen along with the death god, restrained by it's hair. The death god then inserts its arm into the user's soul. At this stage only the user can see the death god. To perform the seal the user need only grasp the target. The death god's arm extends from their chest and grabs the soul of the target, immobilizing them and allowing them to see the death god as well. The death god then performs the sealing. It is also possible for the user to seal multiple targets through the use of shadow clones

If the user cannot pull out their target's entire soul, he can have the death god use it's knife to sever a piece of the soul and seal it. The part sealed will suffer from necrosis, causing extreme pain and leaving the target unable to use the corresponding body part. Orochimaru believed the talented medical-nin, Tsunade, could heal the damage the seal caused to his arms.

Soon after the sealing is completed the death god consumes the souls of the user and the sealed, sentencing them to be locked in combat within it's stomach for all eternity. A seal is left on the stomachs of those that have had something sealed within them using this jutsu. There is a limit to how much chakra can be sealed by the Dead Demon Consuming Seal, Minato Namikaze explained how it was physically impossible to seal away all of the Nine-Tailed Demon Fox's chakra, opting instead to seal half within the Shinigami along with himself, and the other half in Naruto Uzumaki. Minato also implies that it is impossible for a jinchūriki to perform the seal.
