Guardian of Bones

A defensive armor type Ninjutsu created by Kyōya Kaguya whilst utilizing his Shikotsumyaku. This technique is doing by forcing bone plates within his body to break past the skin and push outward, so that his body would be covered in a makeshift bone armor. The bone would then fuse together via chakra to form a sort of skeleton-like armor covering around Kyōya, completely made of chakra enhanced bone. As with all Shikotsumyaku techniues, the bone density can be manipulated at will to enhance defensive capabilities, and from inside this bone armor, Kyo can still produce weapons to perform his dances if need be, since the bones are still an extension of his own skeletal structure, and as such can be manipulated. Due to the hardness of Kaguya bones, this armor can be described as a near impenetrable defense.
