Land of Waves Arc

Land of Waves Arc 

After completing a number of simple, uneventful missions, Team 7, at Naruto's insistence, was assigned the somewhat more difficult C-rank task of escorting Tazuna to the Land of Waves. When they were attacked by theDemon Brothers along the way, who tried to kill Tazuna, they realised that there was more to this mission than a simple escort. Tazuna revealed that his country was under the control of Gatō, who had left the people poor and unable to afford the more accurate A-rank mission payment. By building a bridge that would connect the Land of Waves to the mainland, Tazuna hoped to free the country from Gatō, prompting Gatō to try and kill him. Team 7 decided to help Tazuna, and act as his bodyguards until the bridge was completed.

They were soon attacked by Zabuza Momochi, another of Gatō's assassins, who engaged Kakashi in battle. When Zabuza captured Kakashi, he encouraged his team to escape with Tazuna. Having been of little use during the battle with the Demon Brothers, Naruto resolved to help Kakashi. With Sasuke's assistance, they were able to free Kakashi, who in turn almost defeated Zabuza. However, Haku, disguised as a hunter-nin, intervened, and appeared to kill Zabuza first, in actuality only putting him in a death-like state in order to get him to safety. Kakashi suspected that Zabuza was still alive, and gave Team 7 a Tree Climbing Practice to improve their chakra control. Naruto and Sasuke developed a competition over the exercise, each determined to complete the training first, and subsequently motivating each other to do better.

While Naruto was resting from training one day, he encountered Haku, unaware that it was the same boy he had encountered earlier. The two had a conversation about those who were precious to them, and the lengths they would go to protect them. After Haku left, Naruto finished the training, but was left so tired that the rest of Team 7 allowed him to rest the next day as they went to escort Tazuna. When he woke up, he went to assist them, only to find that they were in the midst of battle with Zabuza and Haku.

Naruto's first use of the Nine-Tails' chakra.

Naruto went to help Sasuke in his battle with Haku, but they were both trapped by Haku's Demonic Mirroring Ice Crystals. When Haku tried to use a volley of needles to kill Naruto, Sasuke stepped in to protect him, appearing to die instead. Enraged by the apparent death of Sasuke, Naruto tapped into the Nine-Tails' chakra, allowing him to destroy the ice mirrors, and subsequently defeat Haku. Before he could kill Haku, however, the mask he was wearing broke away, revealing the face of the boy Naruto had met earlier. Naruto stopped himself, but Haku asked that he should finish the job, since he could no longer be of use to Zabuza. Although Naruto tried to comply, Haku stopped him at the last minute, and went to help Zabuza. When Naruto realised what had happened - that Haku had given his life to save an ungrateful Zabuza - an outraged Naruto reprimanded Zabuza for not appreciating Haku's actions. Touched by his words, Zabuza killed Gatō to repent in an effort to do Haku justice, but died of his wounds. The bridge (now named the Great Naruto Bridge) was completed, and the Land of Waves was saved. With a recovered Sasuke, Team 7 returned to the Konoha. On their way home, Naruto remarked to Kakashi that, even though Haku and Zabuza were their enemies, he still liked them.
