Kaguya Bloodline Limit

Shikotsumkayu (Literally meaning Dead Bone Pulse) is the Kekkei Genkai os the Kaguya clan, which gives them the ability to manipulate their own bone structure. They have free control over the cells responsible for bone growth and replacement, allowing them to maniupulate their bones at will. They could protrude their bones out of their skin with any injuries recieved during this process healing instantly, change their bone density, and could completely regenrate a lost bone. The ability was rare among the Kaguya clan members, only activating for those who were not violent, barbaric and blood-thirsty.
