Shinigami Mask

A mask resembling the Shinigami's face, it resided on a wall inside the Uzumaki Clan's Mask Temple located on the outskirts of Konohagakure, along with several other, similar-looking masks. It allows the one who wears it to call forth the Shinigami by possessing the wearer. The user can then use the Shinigami's tantō to cut open its stomach, which releases the souls sealed within it. However, this ritual usually requires the user to sacrifice themselves as the wound is reflected on the user's body. When Orochimaru used it, evading death, he was able to regain the severed part of his soul and then proceeded to reincarnate the first four Hokage who were also sealed in the Shinigami's stomach.
