Hariken

is a deadly fighting-style created by Gekihen upon obtaining the Byakugan, incorporating it's main fighting style with the use of pressure point attacks.

Usage
The Hyūga Clan possess one of the most feared eyes in the world, and an even more prominent taijutsu obtained through these eyes. This style uses injections of extremely small needles of chakra to damage the chakra pathway and thus the organ(s) connected to that particular area. As a result, the clan focus on mainly swift and soft attacks to the target, making little-to-no external damage. Gekihen, however, experimented with this style and attained a way to improve it. This improved style inhibits both internal and external damage, placing more emphasis on the latter. By aiming for the pressure points in the human body—which are extra sensitive and experience pain significantly more than other areas—he can inflict swift strikes to them whilst also striking them internally, multiplying the magnitude of pain tremendously, and incapacitating them within moments.
