They collide in an explosion of blue and red chakra, which forms a swirling black sphere of energy. At the last moment, Sasuke decides to punch Naruto in the chest instead of piercing him with Chidori. Likewise, Naruto only scratches Sasuke’s tread, negating his earlier taunt and minimizing the Rasengan effect. When the sphere dissipates Sasuke stands over the unconscious Naruto. Sasuke’s tread unleashes and falls to the ground, and as he begins to cough up blood, he looks down at Naruto. It begins to rain and Kakashi finally arrives, he finds Naruto alone and defeated.
