Karin Uzumaki

Karin (香燐, Karin) is a former subordinate of Orochimaru, presumably a former kunoichi of Kusagakure, and a member of the Uzumaki clan. She assisted Orochimaru in his experiments, and was left in charge of his Southern Hideout while he was away. She was later recruited into Sasuke Uchiha's group Taka, which was initially called "Hebi" at the time of its creation, as the sensor of the group.
