Jūgo is a shinobi from an unnamed clan, who was being held at Orochimaru's Northern Hideout. He was said to have gone to Orochimaru of his own free will, hoping that Orochimaru would cure him of his rages. He was later recruited as a member of Sasuke Uchiha's group Taka, which was initially called "Hebi" at the time of its creation.
