Then this leads to a battle between Kakashi and the snake in which Kinoe gets swallowed. Kakashi manages to save Kinoe by killing the snake. Kinoe is shocked by Kakashi's act of saving him although he was targeted by Kinoe. The snakes carcass emits a poisonous fog weakening Kakashi. Kinoe manages to bring Kakashi to a safe spot and saves him by administering an antidote. Kinoe had the perfect chance to steal the Sharingan but could not do it out of friendship. He exits the place with a decoy wooden eyeball which is later discovered by Danzō. Danzō is furious with Kinoe's change of heart and orders a cursed mark to placed on him. Elsewhere Kakashi reported the incident to Hiruzen and Hiruzen sent out a summon for Danzō. Kakashi and Yūgao were sent to dispatch it. At the Root Kakashi and Yūgao are stopped by the Root members claiming that Danzō is not there. Then Kakashi sent Yūgao back to Hiruzen and Kakashi goes and saves Kinoe. On exiting the Root Kakashi and Kinoe are cornered by the members and Danzō. Hiruzen comes just in time to save them and somehow convinces Danzō to let Kinoe join the Anbu that is under him.
