The whole gentle fist style of the Hyuga clan is a mystery to me. If you can put chakra in your hand, and then hit someone in the chest and damage their heart, why cant everyone do that? The talent Neji has is to see the little holes, that I currently forgot the name of, but that is a different attack that he uses his fingertips to hit.

The whole thing is nonsense.

And on an unrelated note. Why doesnt Kiba have to use handseals for his moves in the fight between him and Naruto?
