The first time he saw Haku’s face, Naruto recognized him as the boy he met a few days ago, and changed his mind about killing him. Haku, who took it as a show of pity, reminded Naruto that he had killed Sasuke. He also added that mercy was inappropriate in such a situation, as his life had finally lost its meaning because by losing to Naruto, he had become useless to Zabuza. Still, Zabuza Momochi was the only person who found meaning in Haku’s existence, so he vowed to live his life as Zabuza’s tool. Meanwhile, Kakashi tries to capitalize on Zabuza’s earlier wounds. Knowing that the latter’s sword is soaked in his blood, Kakashi summons his ninja dogs with the goal of tracking down Zabuza by the scent of blood on his blade and capturing him.
