Karin 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. After learning of his death she remains loyal to him by keeping the prisoners of the base in check. Karin has red eyes, matching hair color and an unusual hairstyle; her hair is short and unkempt on one side, and long and combed on the other. She will at times appear tough and in control, particularly when Suigetsu or Jugo are present. When Sasuke Uchiha is around, however, she switches to a flirtatious personality where she tends to imply a team consisting of only the two of them would be considerably better. She has a dramatic and sometimes almost obsessive interest in Sasuke, as she goes so far as to keep one of his battered, sweat-drenched shirts for herself and plans to "ravage" him after everyone falls asleep.
