The Time of Awakening!!

Summary
By putting on his Konoha forehead protector, Sasuke acknowledges Naruto as his equal, both being strong and both knowing what it is to be lonely. However, Sasuke claims that Naruto lacks the power to scratch the forehead protector, and that once he has killed Naruto he will become even stronger. Naruto attacks and Sasuke, his Sharingan having matured, is able to predict his movements and dodge his strikes. He attacks Naruto's openings and repels him. Within Naruto's subconscious, the Nine-Tails grants him more of its chakra, allowing Naruto to obtain the one-tailed form.
