Kaneko Fist is a secretive martial art taught to the members of the Kaneko Clan. This martial art is known as the greatest martial art in existence because of many factors. One of the main reasons stems from how this fighting style uses a latent energy that all members of the Kaneko Clan have: ki. Ki is a type of energy that allows a Kaneko to harness their physical and mental prowess to perform godlike feats, hence its alias Hachiman Fist.
