Living Body Pulse: Immutable Karma King

Living Body Pulse: Immutable Karma Shadow King (生体脈・定業影王, Seitaimyaku: Jōgōkageō) is a technique stemming from the Shihōmyaku.

Overview
Through the power of the Shihōmyaku, the user curses their, granting it independent existence while enabling it to fight on the use's behalf for a variety of purposes. The user see, smell, hear and touch through the shadow itself. Despite this, attacks senses of the shadow itself don't affect the user. Offensively, the shadow can change size and shape to combat opponents, regardless of power. Because of its nature, attacks such as Ninjutsu and Genjutsu are nearly useless against the shadow itself, as it doesn't attack take damage from attacks and lacks organs capable of being affect by illusions. Despite this, powerful techniques can decrease the time the technique is active. By coming into contact with the shadows of others, the shadow is capable of locking their bodies in place, preventing them from moving. Alternatively, it can be used as puppet strings, controlling the movements of all affected targets.

Its movement speed is one of its most frightening traits, moving at to intercept attacks and combat desired opponents. Because the shadow is an extension of the user, it is capable of utilizing any technique within the user's arsenal. Upon the technique ending, the shadow returns to its original state as an optical phenomenon mimicking the user's movements. After a given amount of time, all damage done to the shadow by targets will be reflected upon them, living up to its name sake.
