White Past: Hidden Ambition

Synopsis
Naruto's chakra rages around him wildly. Haku remarks that chakra usually couldn't be seen, yet it was clearly visible. Naruto, still angered by the "death" of Sasuke, had weakened the seal that kept the Nine-Tailed Demon Fox's chakra in place. Surging with power, Naruto healed his wounds and attacked, brutally overwhelming Haku, and deflecting his needle attacks with waves of pure chakra. Haku attempts to flee the circle, but Naruto sees him and snatches his arm with the speed of the Nine-Tails.

Meanwhile, the battle between Zabuza and Kakashi continues. Kakashi is relieved to sense the seal confining the Nine-Tails had only weakened, and had only let a small portion of the fox's chakra out. He decides to end the battle, Zabuza being curious as to how Kakashi would do that when he can’t find him amongst the mist. Kakashi’s only response to this, is pulling out a scroll.

Naruto having grabbed Haku's arm, delivers a powerful punch, sending him through one of the mirrors, simultaneously destroying them all. Naruto rushes at Haku again, ready to deliver another enormous blow. At that moment, Haku's mask comes off to reveal the boy he met in the forest. This causes Naruto to pause his attack. Haku asks Naruto to kill him, as he’s no longer useful to Zabuza, calling himself nothing more than a broken tool. He goes on to explain his past; being born in a small village, and how his parents dearly loved him. However during that time, anyone with a kekkei genkai, a bloodline trait, was feared. When Haku was a small boy, he discovered the powers inherited from his mother. Unfortunately, his father witnessed this, and murdered her out of shame. Just as Haku's father was about to kill him too, Haku subconsciously activated his trait, ending his father’s life. A little while after that day, Zabuza found Haku, taking him in and training him in the most advanced ninja skills.

Kakashi finally uses the scroll he pulled out earlier to use Summoning: Earth Release: Tracking Fang Technique. Though Kakashi can't see or hear Zabuza, he would smell him out instead with these tracking dogs. Earlier, Kakashi let himself be sliced by Zabuza's blade, covering it in blood. Now wearing the same sword, Zabuza is easier to trace. Kakashi then introduces his only original technique: Lightning Cutter.
