This Cursed Seal is given by Danzo to all members of the ANBU subgroup Foundation, to ensure no information about Danzo or the organization falls into the wrong hands; something that would not only endanger the organization, but even Konohagakure itself. As the Foundation was an organization of top secrecy, committing less-than-respectable acts in the dark to support the village, this seal was designed to keep it so.

When the wearer of this Cursed Seal speaks about anything related to Danzo, their entire body will be paralyzed, taking away their ability to speak or move. It is applied to the tongue and takes the shape of three solid lines and two broken lines from the back of the tongue to the tip, possibly a hexagram. It could either be the hexagram ䷞ (咸, Japanese: "kan," Chinese: "xián"), which can be interpreted as "influence," or it could be the hexagram ䷠ (遯, Japanese: "ton," Chinese: "dùn"), which can be interpreted as "concealment."
