Despite Naruto's timely appearance, Sasuke is more than willing to sacrifice their scroll to ensure their survival. Before he can do so, Naruto takes the scroll from him, believing that the real Sasuke would never willingly give up. Naruto begins fighting the Grass ninja and his snakes, tapping into the demon fox's chakra in the process.
