Body Consciousness Transfer Technique - a hidden technique of the Yamanaka clan, establishing a direct telepathic connection between the user and one or more recipients. The technique is not limited to transmitting words: visual images, memories, and even strong emotions can be broadcast through it. At the same time, connected participants are able to communicate not only with the channel's creator but also with each other while the connection is active. The more people are connected, the greater the physical strain on the user - prolonged maintenance of an extensive network risks injury, and the stable operation time decreases. The range of coverage also depends on the operator's personal strength.
To expand the technique's capabilities, the Intelligence Division of the Allied Shinobi Forces uses special communication devices based on chakra transmission. The stationary version - a large apparatus with two batteries and a helmet covering the upper half of the face - is used in headquarters to coordinate entire fronts. The portable version is significantly more compact: it is attached to the back, and a thin wire connects it to the wearer's head, allowing them to stay in touch in field conditions. It was through a stationary device that Inoichi Yamanaka managed to unite the consciousness of all Allied forces for a few seconds, after which he developed a nosebleed - a clear demonstration of the limit even for a master.
