Damage Points: N/A ( Death )
Description: The user, or his clone, makes nine handseals and then claps his hands. This summons the Shinigami, who appears behind the user and wraps its left arm with prayer beads. The soul of the user is visible, bound to the Shinigami. The Shinigami then extends its hand through the user's chest, grasping the opponent if he is within short range, and begins pulling out his soul. Once the Shinigami has grasped the opponent, he is completely immobile, although he can use weapons, summonings already existing, etcetera to try and kill the user before the technique completes. At the user's command, the Shinigami then performs the sealing, locking away the victim and the user's soul to battle for all eternity in the Shinigami's stomach.
Note: If used by the user himself, causes him to die.
Note: This technique can be used only a maximum of two times by clones, and once by the user himself.
Most powerful seal seen so far. It basically seals anything within the death god stomatch's. It was shown that Minato had a different way of using it by sealing the yang chakra of the kyuubi within himself by making the arm go through him and what not.
