Karin cautions Sasuke about Jugo, but he’s not concerned. Knowing something about Jugo, Suigetsu asks what the problem is. Karin explains that Jugo voluntarily became a prisoner of Orochimaru in order to find a cure for his propensity to kill. Experimenting with Jugo, Orochimaru created the Cursed Seal Technique. Now that Orochimaru is gone, the bearers of one of these cursed seals have begun to run rampant at the base where Jugo is being held. One escapes and finds Sasuke, and the others approach the base. He attacks them, but Sasuke instantly inflicts slashing wounds on him.
