After infusing chakra into the victim's shadow, the user then sinks into the shadow becoming one with it. This technique temporarily establishes control over the victim's mind and body. While the technique is in effect, the victim is temporarily stunned and can serve as a human shield. The user has to hold their breath, but they can talk through the victim. As soon as the user's breathing recommences, the technique is cancelled and their ultra-thin body expands again retaking its original thickness.
