Cursed Tongue Eradication Technique

This cursed seal is given to all members of a certain organization, to ensure no information about their leader or the organisation falls into the wrong hands. The contents of the seal activate once one jeopardizes said intel.

When the wearer of this cursed seal speaks about anything incriminating related to its purpose, 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.

In order to keep his practices with the Shinigami and whatever allotted information is to come with such, he has placed said seal onto each member of his Death Knight organization.

Influencing his own will into the seal, allows him to monitor and keep track of his branded members; giving his use of the technique to prevent those who shouldn't know of his secrets, from finding out.
