Name: Karin
Nickname:[If you have one]
Age: 16
Gender: Female
Rank: B-rank
Village: Otogakure
personality: 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, like many girls in Konoha before her, has a huge infatuation with Sasuke Uchiha. Her infatuation, however, is an obsession to the point of fanaticism. For example, when Hebi was resting in a village to take care of the wounded Sasuke after his battle with Deidara, Karin planned to drug Suigetsu and Jūgo to "ravish" Sasuke's unconscious body. She later revealed that she had kept one of Sasuke's sweat-drenched shirts. Karin also implied that a team consisting of just her and Sasuke would be much better than partnering with Jūgo and Suigetsu. Suigetsu indicated that Karin had some history with Sasuke, but this has yet to be elaborated upon in the manga. In the anime, however, it was revealed that her crush on Sasuke began when she aided him in tracking down several prisoners that attempted to escape from Orochimaru. She seems to rate men on their chakra level, and claims that Suigetsu's chakra digusts her. Karin was very displeased when the Fifth Mizukage flirted with Sasuke, and called her an old hag for it.
Despite her crush on Sasuke, Karin currently fears him due to his cold and cruel attitude, as well as a darker chakra, and she questions what happened to him.
Aside from this, Karin shows great intelligence, being able to sense, heal and even suppress others chakra.
Appearance: Karin has red eyes, a matching hair color, and an unusual hairstyle: her hair is short and unkempt on one side, while long and combed on the other. She wears brown glasses, a lavender uniform common for Orochimaru's subordinates, short black shorts, long black panties with shoes.
Bio: Hunt for Itachi arc
Sasuke recruited her as a member of Hebi. While Sasuke admitted that she might be troublesome sometimes, he also noted that her special abilities made her useful. Once the team was completed, Sasuke sent Hebi out in multiple directions to try and locate Itachi Uchiha. While on the search, Karin passed Sakura Haruno, although the two did not acknowledge each other. After Deidara's suicide explosion, the rest of the team regrouped and took Sasuke to an inn to recover. When Karin went out for supplies, she sensed the Eight Man Squad approaching, and warned the team. It was her plan to use Sasuke's old clothing as a means to distract the squad from catching them. When they finally got back on Itachi's trail, Karin stayed behind with Suigetsu, Jūgo, and Kisame as Sasuke went ahead to battle Itachi.
