The Kodon Clan

The Kodon Clan (虎呑一族, Kodon Ichizoku) is a clan of the Howling Wolf Village. They are able to make a medicinal form of saigenzai known as Kotarō within their bodies; although only Kodon can do this, it is not a kekkei genkai.

A sealing technique that is passed down within the Kodon clan, allowing its members to seal Rōen, a wolf-like monster that has terrorised them since ancient times. The seal must be placed at Rōen's weak point, on the back of its head. If successfully applied, Rōen's body gradually turns to stone.
