Bone Dust World Method behaves in the same way as Iron Sand World Method. This technique uses Bone Dust to create a gigantic sphere of branching spikes. The user first creates two masses of Bone Dust of opposing magnetic fields (through the use of the Shikotsumyaku's Ferrokinesis) and then merges them together. This causes the magnetic forces to instantly increase and the repellent force created by the two opposing magnetic fields scatters the Bone Dust across a vast area.
