Zero Visibility: The Sharingan Shatters

Naruto and Sasuke both attempt to destroy the ice mirrors, their respective Shadow Clone and Fireball Techniques having no effect. Realizing that Haku's Crystal Ice Mirrors are actually an Ice-Style Kekkei Genkai, a genetic trait in certain ninja, Kakashi decides to use his Sharingan to quickly end his fight with Zabuza. But Haku told him about Kakashi's methods during their last fight, Zabuza has the advantage as he uses his Hidden Mist technique to counter Kakashi's Sharingan and force the ninja to anticipate his opponent's next move. While Kakashi rushes to Tazuna and Sakura under the assumption that Zabuza would attack them, he ends up leaving him himself open from behind as Zabuza lands a strike with his Kubikiribouchou sword.
