Like her teammates, Kin appeared to be overconfident in her abilities. She had a strong dislike towards girls like Sakura due to her apparent vanity for her hair and criticises her for focusing on her appearances rather than training, even going so far to call Sakura a female swine and “boy-chaser” in the manga. Like her teammate Zaku, she loses focus on her opponent's tactics when overconfident, as seen when she didn't recognise that Shikamaru could use the very thin shadow created by her wire strings against her when she boasted about her abilities. Kin also preferred to toy with her opponents by defeating them slowly and painfully, as stated by her during her fight with Shikamaru in the preliminaries.
