Fūjinga

was a powerful yōkai sword used by Ryūra, the leader of the Shitōshin. It was able to control air movements, and by slashing through the air in quick succession, one could attack an opponent with the surrounding air without actually having to be near them. It could also summon a powerful defensive move, Earth Dragon Gale. Its partner was the Raijinga, or "Thunder blade"; together they proved a formidable force, even for an experienced fighter like Inuyasha. Ryūra believed his blades to be superior to Inuyasha's Tessaiga.
