Karin (香燐) is a former subordinate of Orochimaru, who assisted him in his experimentations and was left in charge of one of his bases while he was away. She has red eyes, a matching hair colour, and an unusual hairstyle: her hair is short and unkempt on one side, while long and combed on the other.
BackgroundKarin lived in a small village that was burnt to the ground during a war. She was the only survivor, completely unharmed. Orochimaru randomly found her after that and asked how she survived, to which she answered that she could tell that huge groups of people were coming. Orochimaru then brought her to Otogakure, where she served as a jailer at one of his bases. Unlike the rest of the team, Karin was genuinely loyal to Orochimaru, going as far as to refuse to release Orochimaru's prisoners, even after his defeat.
