White Past: Hidden Ambition

This episode begins with Naruto's chakra raging around him wildly. Haku remarks that chakra can not be seen yet it is clearly visible. Naruto, still angered by the death of his rival, has broken the seal that keeps the Nine-Tailed Demon Fox's chakra in place. Naruto rushes at Haku wildly in an attempt to avenge his rival. Twice Haku attempts to kill Naruto with throwing needles but on both occasions Naruto uses the Nine-tailed fox's chakra to push the needles out and heal himself. Naruto finally rushes Haku and breaks the mirror Haku was hiding in. Haku then comes out from a shard of the broken mirror in an attempt to end the battle but Naruto quickly dodges. When Haku tries to return to a mirror Naruto grabs his arm.

Meanwhile the battle between Zabuza and Kakashi continues. Kakashi senses that the seal for the Nine-tailed fox has weakened. He decides to end the battle quickly. Zabuza is curious as to how Kakashi will do that when he can not find Zabuza. Kakashi's only response to this is to pull out a scroll.

Naruto, having grabbed Haku's arm, delivers a powerful punch, sending Haku through one of the mirrors and through that process, destroying them all. Naruto rushes Haku again, ready to deliver another powerful punch, but at that moment Haku's mask came off to reveal the boy he had met in the forest. This causes Naruto to withdraw his punch. Haku asks Naruto to kill him because he is no longer useful to Zabuza, calling himself nothing more than a broken tool. Haku then goes on explaining his past, how he was born in a small village and how his parents loved him. However during that time anyone with a Kekkei Genkai, a bloodline trait, was feared. When Haku was a small boy he discovered he had one, from his mother. Unfortunately his father had saw what he had done and killed Haku's mother. Just as Haku's father was about to kill him Haku tapped into his unknown powers and killed his father. A little while after that day Zabuza found Haku and took him with him to train him in the most advanced ninja skills.

Kakshi finally uses the scroll he had pulled out earlier to use the Summoning Technique: Earth Release: Tracking Fang Technique on Zabuza to track him. Kakashi reveals that even though he could not see or hear Zabuza he would be able to smell him out. He also reveals that earlier he had let Zabuza cut him so that Zabuza would be covered in his blood and easier to track. Kakashi then says he will introduce Zabuza to his one and only original technique: The Lightning Blade.

Haku keeps asking Naruto to kill him. After some time Naruto finally accepts to kill Haku, but not before saying if they had met some other way, they probably would have been friends. Haku thanks him and Naruto rushes at him with his Kunai knife. Just as Naruto is about to attack Haku senses Zabuza is in danger.
