The Gentle Fist is a form of hand-to-hand combat used by members of the Hyuga clan. It inflicts internal damage through attacking the body's Chakra Pathway System, subsequently injuring organs which are closely intertwined with the area of the network which has been struck. To do this, the user surgically injects a certain amount of their own chakra into the opponent's chakra pathway system, causing damage to surrounding organs due to their proximity to the chakra circulatory system. Even the slightest tap can cause severe internal damage, hence the name "gentle" fist.
