For a Friend

While Naruto Uzumaki is battling Sasuke Uchiha, Kakashi Hatake learns of Sasuke's defection from Tsunade. He is confronted by Sakura Haruno, who he tries to comfort before immediately leaving to search for Sasuke and Naruto. Meanwhile, believing Naruto to be his closest friend, Sasuke prepares to kill him, finding the loss of Naruto to be an acceptable price for the Mangekyo Sharingan. Naruto's Rasengan and Sasuke's Chidori clash, though neither is capable of overpowering the other. Activating his cursed seal in order to gain an advantage, Sasuke makes a plan of how to murder him. He starts by mercilessly beating and thrashing Naruto and uses his Chidori to pierce through Naruto, just missing his heart. While Sasuke thinks the battle to be won, the demon fox's chakra begins to envelop Naruto and the wound Sasuke inflicted starts to heal. Infused with the demon fox's strength and now willing to break Sasuke's body in order to bring him home, Naruto attacks.
