I haven't been able to find it but i thought the same thing.I do believe that it does, I forget where it was specified.
thanks so much i thought the same way until this idea just hit me, i doubt well ever find out if this is what kishi really intended the jutsu to be but I hope it is and if it isn't, well this version makes a pretty cool jutsu anywayThis has to be the best theory on Limbo i've ever read. Really made me reconsider the technique. I didn't quite liked Limbo, it didn't have that "wow" factor for me, but after reading this, i began thinking of countless possibilities the jutsu may have.
