Sakura shocked by the unfolding scene, Naruto takes it upon himself to take the lead. He performs the Kage Bunshin (Shadow Clone Jutsu) and attacks. Zabuza's power easily overwhelms Naruto but with Sasuke in the clear, Naruto throws a Fuuma Shuriken and Sasuke does the Shadow Windmill technique in the hopes of a direct hit. Just before impact, the flying blade zooms past the clone on a collision course with the real Zabuza. Zabuza catches it with his free hand but not understanding the technique, the second blade comes right at him. Zabuza laughs and leaps over this second attack, but is shaken by a sudden vision from behind. To his amazement, Naruto appears, and throws a kunai straight at Zabuza.
Having no other choice but to move out of the way, Zabuza pulls his hand from Kakashi's watery prison. But as he dodges, the kunai nicks his face and goes through the clone. Angry by such an action, Zabuza proceeds to spin the shuriken he caught and throw it back at the now open Naruto. But right before the blade takes flight, blood fills the air. Kakashi stands before Zabuza with his hand raised, stopping the once spinning blade. Kakashi praises the boys on a job well done and taunts Zabuza for being beaten by kids. Naruto then proceeds to tell of the plan that was devised to use himself as a Fuuma Shuriken and let Sasuke toss him at the enemy to insure the freedom of their teacher.
Kakashi and Zabuza now have a standoff and then both split off and land away from each other. Zabuza begins a series of hand seals, which are:
Ox, Monkey, Rabbit, Rat, Boar, Bird, Ox, Horse, Bird, Tiger, Dog, Tiger, Snake, Ox, Sheep, Snake, Pig, Sheep, Ox, Monkey, Bird, Dragon, Ox, Horse, Sheep, Tiger, Snake, Rat, Ox, Monkey, Bird, Rat, Boar, Monkey, Dragon, Bird, Ox, Horse, Sheep, Tiger, Snake, Rat, Monkey, Rabbit, Boar, Dragon, Ox, Rat, Ox, Monkey, Bird, Rat, Boar, Bird,
with quick reflexes, Kakashi is copying every word and movement that Zabuza is doing. They both perform the Water Dragon Jutsu at the same time, two giant Water Dragons (as the name suggest) appear and intertwine with one another. The attacks clash and there is a great explosion of water, as the four look on they see the two battling figures in a dead lock. Just as Zabuza is trying to figure out what is going on, a lone masked figure appears unnoticed by the fighters or the onlookers. Breaking the deadlock, the two encircle each other only to do the same action. Kakashi even goes as far as to finish his sentences, now having Zabuza firmly in disillusion; Kakashi performs a genjutsu that shows Zabuza a mirror image of himself. With Zabuza's confidence broken, Kakashi does the Water Style - Water Vortex jutsu.
Caught off guard by the sudden attack, Zabuza is blown away in the ensuing torrent and is washed away through the forest. Zabuza cannot figure out how Kakashi is doing it "He knows my moves before I do". Struggling within the current, Zabuza tries to escape but in the effort is washed up against a tree and then struck in the arms and legs by Kakashi's kunai. Left with no other choice other than death, Kakashi prepares to deal the final blow. Then out of nowhere, 2 needle like darts rip into the side of Zabuza's neck. As he falls, the others look to see where the attack came from. Seeing that it came from the now visible masked assailant, Kakashi jumps down and inspects the newly dead corpse. He reveals that the masked individual is a hunter ninja from the Hidden Mist Village.
Faced with the death of this fierce opponent, Naruto prepares to attack the masked ninja. Halted by Kakashi for his rush to conclusions, frustrated by the fact the masked ninja is just a kid like them and yet did what they could not, takes its toll on Naruto. Kakashi comforts him and then the masked ninja then says that he will dispose of the body and that there is no other need for their help. Naruto, having lost all confidence in himself, begins to beat the ground in frustration. Kakashi tells Naruto to do better next time, and just as the mood is lightened by Tazuna's cheerful words and the group starts to head out, Kakashi passes out.
