Summary
This arc was the first arc in both the manga and anime of Naruto. This is also Team 7s first A rank mission. The goal was to transport the bridge builder Tazuna back to his home. But, Zabuza Momochi was hired by the evil Gato to kill the bridge builder. After Team 7 and Zabuza fight, Haku comes and takes him away. This battle shows Kakashi Hatake in battle and Sharingan is mentioned for the first time. After the battle, Kakashi is too weak from the Sharingan. He teaches Team 7 about chakra control and how to climb a tree with no hands. Sakura was amazing, though Naruto and Sasuke failed. After the chakra control lesson Kakashi realizes that the ANBU was a fake, working for Zabuza. After team 7 learns of Inari's stepfather and the  Gato empire, they head to the construction of the bridge. Zabuza appears from the mist, showing that he was alive. After a short talk between Kakashi and Zabuza, Haku and Sasuke commence in battle as Zabuza threatens to kill the bridge builder if Kakashi interferes. At first Haku seems to prove more fast and agile, but Sasuke demonstrates his speed and quickness which shocks both Zabuza and Haku. As the battles continues Haku demonstartes the ability to use single-handed hand signs, an ability which Kakashi noted that he has "never seen before".
