A teacher at the ninja academy, Mizuki told Naruto that there was another way to pass the test. That is to steal a scroll from the Third Hokage. All Naruto had to do was to master a technique from the scroll and he would pass the test. Unknown to Naruto, Mizuki was tricking him. He only wanted the scroll for himself as this scroll contained hidden and forbidden techniques important to Konoha.
But Iruka found out Mizuki's plot and intercepted Naruto and Mizuki. During the confrontation, Naruto found out that he was the container of the Nine Tailed Demon Fox, and finally knew why the villagers hated him. Mizuki urged Naruto to release the demon fox's power and to kill Iruka. But Iruka intervened and told Naruto that he was not a monster. Enraged, Mizuki attackes Iruka but before he could strike, Naruto unleashes the technique he learned from the forbidden scroll. He creates hundreds of clones and attacks Mizuki. Shocked that such a prankster and failure could master a high level technique in a short time, Mizuki is stunned and finally defeated by Naruto.
