Oshō

Oshō (和尚, Oshō) was the head of the Chagama Clan before his death, as well as the father to Gaman and Angya. Having much resentment towards Sunagakure, Oshō would devise a plan which involved his son. Living among nature once again, Shukaku was taken by Oshō who was strong enough to subdue him. The tailed beast would then be sealed into his son Gaman in a revenge plot to destroy the village. The sealing was successful and a year would pass before he was thwarted by the and. Standing by his objectives, Oshō was caught in the destruction of the Chagama hideout as well, as well as his wife. In the end, he left behind two children who were then put into the care of Gaara.
