Needle Fist

Needle Fist (拳針, Ken Hari) is a fighting style used by members of the Tsukiji clan. The style is close to the technique of the Gentle Fist of the Hyuga clan. The user inflicts internal damage by attacking with chakra emanating as needle-shaped fists, eventually, it can damage organs that are closely intertwined with the area of the system that has been hit. The user surgically injects a certain amount of its own chakra in the opponent's body. Even the lightest touch can cause serious internal damage.

Because the Tsukiji clan does not have the Byakugan or any other Dojutsu this is a less precise technique but still lethal.

This technique is very difficult to perfect so not all clan members are able to get it. It requires great control over the chakra and a lot of skill in hand-to-hand combat.
