The ninjas who belonged to the clan participated in the First Shinobi World War and became feared because of their abilities to rejuvenate an opponent to the point being to weak to fight. However, there were only a few talented shinobi capable of doing those techniques, so the clan retreated from battles and became unknown, trying to avoid an invasion. The clan members built their homes on the Fushichō Mountain and became scholars. Only about two hundred members still remain. Their techniques have faded into oblivion and most people believe they never existed at all.
