I just think that Rokushiki is a very specialized form of training that accomplishes much of the same as Haki training does. Tekkai could be a lesser form of Armament Haki, and Kami-e could be related to Observation Haki but I may be going too far. I think that it all relates to different paths (training forms in the Marines and the other cultures of the World) to similar outcomes. What do you guys think?
I don't know if this discussion has already happened, and if it has been the case I will look it up.
