Yes. It's actual name is 柔拳, or the soft/gentle fist. It's originally an ancient Chinese style of Martial arts. It's derived on Taoist mysticism and the "Bagua" or eight symbols concept. Hence why all of Neiji's techniques are multiples of 8. The style is basically on a flexible and natural use of motion which maximizes momentum, and in turn, power. The chakra points are similar to the "XueDao" or the Blood Paths on one's body. Acupunctures claims to open these blood paths on your body.
