what if she was simply 'throwing' the paper? why woudl she take damage from it?
dats like if Kisame used a suiton technique and Itachi used a Katon technique why would either of them take damage? its' not like they are lobbying their bodies at each other directly they are using ninjutsu against each other.
If i throw a paper plane at you and you open a flame thrower to burn it down why would u assume that i'd be hit by the flames too? I could be very far away throwing that paper plane.
