Shikinaru

(Setting Naruto AU) Look she's a demon that was sealed inside you. You happen to get along with her and you were able to harness and gain a hold on her massive amount of chakra that surpasses Kurama's. Your Ninjutsu is based off ice and snow. Like Gaara but with ice and snow... Anyway these are the Chunin exam finals and you're fighting Gaara. You replace Dosu. (if you know who that is)
