I know right? You must be noticing my hair. I straightened it yesterday after I took a shower. Anyway, the Kaguya KG, called Shikotsumyaku, allows us to manipulate and remove the bones in our bodies. On top of being able to control our bones, we are able to harden them much past the capabilities of even chakra enhanced samurai blades. Finally, due to our ability to control our bones, our bodies regenerate at a quick pace and things that might pain others don't effect us as much, which is a blessing and a curse. For example, our bodies can take a beating, but it is harder for us to break out of genjutsu. Anything I missed?
