Neodymium Bone Snake

This technique is usable after preforming the Magnetic Bone Control technique. Using this, the user will magnetize the iron in the body to it's maximum, allow them to control all metal in the range of 500 feet. By manipulating their bone structure, they create a massive magnetic snake, using the accumulated iron in their body, as well as bone. This snake can move extremely fast, especially since wind resistance isn't a factor because it's composed of bone. This snake is able to defend the user at will, as well as shoot bone spikes from different points on it's body. Oni Kaguya used this technique to defeat the Seven Ninja Swordsman of the Mist, but died as a result of running out of chakra, as well as iron poisoning while preforming this technique. Oni Kaguya used this against the Seven Ninja Swordsman of the Mist, and managed to kill 3 of its members in combat; Jūzō Biwa, Kushimaru Kuriarare, and the sword master himself Mangetsu Hōzuki.
