Jikankizami Clan

The Jikankizami Clan are the foremost sealing clan in the ninja world. For fear of their lives, due to what happened to the Uzumaki clan, the Jikankizami clan have created a stronghold on the face of a mountain around an hour's walk from Iwagakure, sealed to such an extent it is truly impenetrable, and is largely self-sufficient, providing perfect protection for the clan. Arekusu Jikankizami is the only known practitioner of the clan not in the stronghold.
