Death Technique: Dance of the Sacred Lotus

One of Kyōya Shirogane's most powerful and potent techniques, almost a certain kill technique, honed after years of intensive training in the formation and control of crystalline structures. After the breaking down and destruction of larger crystalline structures, Kyoya allows the crystal structure to break apart and continue to break apart until the only remnants are extremely small airborne fragments of crystal that float through the air, easily carried by the wind, too small to be seen by the naked eye alone. These fragments are both carried by the wind currents to travel, but are also attracted to an opponent's chakra signature, as a way to ensure that the fragments are to stay within the range of an opponent's inhalation and exhalation. The fragments, fine enough to be inhaled without issue, can then spread throughout the bloodstream, chakra surrounding the fragments to keep them from being wore down or otherwise negatively affected by the body's fluids. The crystalline fragments can remain within the bloodstream for an extended period of time, remaining within the body for a period of up to three hours. Upon Kyoya's formation of the tiger handseal, the true, lethal nature of the technique comes to light. The crystal powder present within the body, the tiny individual crystal formations would then begin to expand and grow within the body, rapidly morphing into irregular sharp spikes that branch off irregularly into various angles, essentially attacking the body from within. These spears, made of chakra enhanced crystal are easily capable of cutting and ripping through organs and other vitals, and can literally rip the body apart from the inside out, the spikes breaking way to the exterior, ripping through the flesh and bone, effectively and completely mutilating a person's body.
