Shikotsumyaku: Wind Cannons

The user uses their Shikotsumyaku ability to manipulate their clavicles. The bones snap off the sternum, shooting straight up and out of the skin, still connected to the scapula on both sides. The clavicles then form cannon barrels, about the size of a gun's. From there, wind release chakra is pumped from the chakra network, into the bones to the clavicles, which shoot out wind bullets at an opponent which can tear through the body, or create cuts (depending on the amount of chakra put in). They can also just spew out wind gusts or different forms of wind out of the cannons as well.
