Raijinga

was a powerful yōkai sword used by Ryūra, the leader of the Shitōshin. It was able to create bursts of electricity and summon Ryūra's most powerful attack, Dragon Thunder. Its partner was the Fūjinga, or "Wind 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.
