In your first response are you referring to neji feat versus kidomaru? If so I don't see what that has to do with what were saying were not discussing can any hyuga destroy organs but can they one shot anyone with gentle fist?
Thats the point you can attack 1 point and seal it off all you need is to deceive your opponent. And if killing is an issue all Hyuga(minus Hinata) can perform straight up kill shots.
For example if himawaris feat against Naruto was nothing then any kid hyuga can one shot madara.
Madara isn't Naruto so let's not go there. Your right in the general sense all you need to do is teach or train Hyuga to attack 1 point and develop strategies to force opponent to expose said point.
And. I don't get the point of your second response if you can one hit ko someone why don't you.
And lastly the point of palms technique is to close chakra networks I think in the series there's 360 in total and as they get more experienced they can close more.
The only reason I can think off is because 1 hit Ko's would make a story very short.
Closing 360? It doesnt quite work like that why bother closing 10, 20, 32, 64 when 1 is necessary Hyuga should train for that and develop strategies to make opponents expose the 1 point.
But trying to close chakra networks becomes pointless if you can one hit ko anyone and this would make the byakugan super op in general.
Of course but it's confirmed that 1 point is all that's necessary like I said I don't see any reason past the Head House being bored and deciding to create the jutsu.
I think all we're going to do is have a back and forth on the same points so there's no point continuing this unless there's something else we've missed.
