Awakening…!! (覚醒…!!, Mezame…!!) is chapter 27 of the Naruto manga.
Sasuke and Naruto are becoming exhausted by Haku's relentless attacks. However, the attacks are becoming increasingly less successful, with Sasuke slowly being able to not only follow Haku's fast movements but to react and avoid the attacks entirely. Realising that this is because Sasuke has awakened his own Sharingan eyes, Haku moves to kill Naruto so that he will have an easier time fighting Sasuke. Meanwhile, Kakashi has been badly wounded by Zabuza. Zabuza points out that he will soon die just like Sasuke and Naruto, but Kakashi has faith in them in their survival. Elsewhere, Naruto finds that Sasuke has used himself as a shield against Haku's attack. Naruto asks why Sasuke would do that, but Sasuke does not know why. He laments that he did not have a chance to kill his brother before seeming to die. Enraged by the loss of Sasuke, Naruto vows to kill Haku.
