The Tenzoku were once one of Uzushiogakures prominent clans, known for there unique kekkei genkai that allowed them to manipulate portals at will. During the destruction of Uzushiogakure however they were forced to scatter throughout the world. Today they can be found in just about any village, and even though they are few and far between, the customs and traditions are completely intact. This is due, again, to the clans kekkei genkai allowing them to be connected to eachother no matter how seperated.
