About the rasengan chidori argument. An example of each being used on a person. Chidori, pierced through Haku, pierced through Gaaras defense, pierced through Gaara. Conclusion? Chidori is ment to pierce.
However it didnt pierce through Naruto.
Rasengan, a chakra bullet that does NOT pierce but burn rips and basically blows up its target. Cuts holes through trees and rocks, BUT badly cuts and burns Kabuto. Conclusion? The Rasengan should not nick sasukes head band unless it was part of the wind.


However also notice that niether of their attackes were in there origional forms. Both other attacks cancelled each others out into pure chakra, a chakra that they seemed to share on page 2 (58). I think that both attacks were toned down by the others thus the reason why Naruto's torso is intack, and Sasuke still has a head.

Last note, what happened to Sasukes headband that feel of. Did he pick it up, or leave it?
