Kakashi damages Zabuza’s hands, stopping him from attacking further. Seeing that Zabuza is no longer able to kill Tazuna, Gato shows up with a gang of thugs to finish the job himself. Noticing Haku’s body and remembering how Haku broke his arm, Gato defiles his corpse. Although this angers Naruto, he’s even more angry that Zabuza doesn’t seem to care. Zabuza reminded him that both he and Haku were ninjas: tools for battle. They are not supposed to have any emotions or attachments. Naruto explains that this does not apply to Haku, as he cared about Zabuza. Knowing that Naruto is right, Zabuza laments that he never appreciated Haku. Wanting to repent, Zabuza takes a kunai in his mouth and breaks through the thugs to reach Gato. He decapitates Gato and then walks up to Haku and falls down beside him, after which he dies.
