Karin is beatiful girl in naruto shippuden movie. Karin lived in a small village that was burnt to the ground during a war. She was the only survivor, completely unharmed. Orochimaru found her after 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 and, in the anime only, have them killed for speaking of his death, even after his defeat.
Karin has a fluctuating personality; she will at times appear tough and in control, to the point of being violent, and at other times will appear highly flirtatious. She annoys Suigetsu, who she attacks whenever he voices his general opinion of her. She seems to rate men on their chakra level, and claims that Suigetsu’s chakra disgusts her.
She, like many girls in Konoha before her, has been infatuated with Sasuke Uchiha since they first met; when he saved her during the Chūnin Exams. According to the anime, her interest in him began when they tracked down some of Orochimaru’s escaped prisoners together. Karin’s infatuation borders on obsession to the point of fanaticism. For example, when Hebi was recuperating after Sasuke’s battle with Deidara, Karin planned to drug Suigetsu and Jūgo and then “ravish” Sasuke’s unconscious body. She later revealed that she had kept one of Sasuke’s sweat-drenched shirts. Karin does not make much of an attempt to hide her feelings, frequently suggesting to Sasuke that they should spend time alone. Karin was similarly very angry when the Fifth Mizukage flirted with Sasuke, and called her an “old hag” for it. Despite Sasuke’s chakra becoming increasingly “darker” according to Karin and his trying to kill her, she still finds him attractive.
