So far this is the logic that has Naruto winning.
A. Naruto somehow starts like five inches away from inuyasha and forms a rasengan before inuyasha can even get in a single slash. This wouldn't work because it would require him to start closer then he should, and he would have to be much faster.
B. Naruto starts quite a bit away, and Inuyasha windscars. Naruto somehow teleports like half a mile and leaves a stick in his place. Yeah. Since when can Naruto just spontaneously teleport all the way across a battlefield?
You're forgetting that there is no such thing as a demonic aura in naruto, its all chakra. so the back lash wave would be practically useless against naruto, im pretty sure they only called the kyuubi a demon because of its phycological impact. As for the tetsiegas wind scar, naruto easily has the speed needed as has been demonstrated in the fight with sasuke that only a fully evolved sharingan could spot his movements, let alone the fact that the wind sorceress could divert the wind scar with her attacks. Naruto wins hands down.
