I have heard that there are male INTJs represented in anime, such as Light Yagami from Death Note and Lelouch from Code Geass, but it's hard to find female INTJs in anime. If you know any female INTJs in anime please respond.
Let's see... There's Kiryuuin Satsuki from Kill la Kill (she is atleast an xNTJ) and perhaps Senjougahara Hitagi from Bakemonogatari, although she could be an ISTP too. There aren't many female INTJ anime characters unfortunately.
