Cursed Seal of Salvation

The Cursed Seal of Salvation is an original created by Sōjōbō after experimentation on a dozen former Prisoners of Orochimaru who also were implanted with a Cursed Seal. The Cursed Seal takes the form of a two-fold tomoe and is centered onto his back. Its abilities are remarked to "match the chakra signatures of the Yata no Kagami". The extent to the Seal is still unknown.
