Raijinga

was a powerful yōkai sword used by Ryūra, the leader of the Shitōshin. It was able to create bursts of white-colored lightning/electricity and summon Ryūra's strongest and most powerfully destructive attack, Dragon Thunder. Its partner was the Fūjinga, and together they proved quite a strong and formidable force, even for a highly experienced fighter like Inuyasha. Ryūra believed his blades to be far stronger and superior to Inuyasha's Tessaiga.
