Kohaku no Jōhei

The Kohaku no Jōhei is one of the treasured tools of the Sage of the Six Paths. Some time later it fell into the possession of the Gold and Silver Brothers. Kumogakure would later wrest possession from the brothers. It has the ability to seal anyone within it, if the target responds when called by the wielder of the pot. If the person responds, the pot records their soul and then seals them.
