Hakyōmei

is a conceptual armament created by Kazuhide through the use of Tamahagane. When invoked it takes the form of ethereal barrier composed of countless mirror shards. The shards themselves can assume a variety of configurations in order to most effectively shield against assaults.

While Hakyōmei possesses notable defensive potential against physical assaults, able to withstand a great deal of punishment, its true power becomes apparent against energy-based attacks. While facing such an attack, Hakyōmei severs and reroutes portions of the energy being used. In addition to disrupting the maneuver, decreasing its natural potency, the rerouted energy can be directed against the incoming attack, counterbalancing it. As such, Kazuhide is able to utilize a portion of the opponent's own to defend against an incoming technique.

This armament's ability to reroute energy also allows for a sample of unique energies to be stored by Kazuhide for future use in the forging of Tamahagane weapons. It is in this manner that he was able to forge Chikakage and Nagamitsu, and later Muzō Jōman. In terms of more active practice, energy siphoned by Hakyōmei can be released in a offensive shock wave of non-elemental chakra, allowing the user to counter close-range targets. The strength and size of the wave of energy depends on amount of chakra siphoned, and rerouted, by Hakyōmei.
