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 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 much stronger and more powerfully superior to Inuyasha's Tessaiga. Ryūra, along with his swords, were destroyed when Inuyasha killed him. They reappeared when the essence of the Shitōshin merged into a single being with Ryūra as the dominant personality. They were destroyed for good when Inuyasha combined his Bakuryūha with Kagome's sacred arrow against them.

Attacks

 * This technique is similar to that of Sesshōmaru's initial Sōryūha where he has lightning strike his enemies as well. There are some differences, however, where rather than generating the lightning directly from his blade and slashing it forward, Ryūra points the tip of his thunder blade towards the sky and it calls down a lightning bolt directly from a cloud to electrocute his opponents.
 * Tornado: Using both swords, Ryūra can create a spiraling tornado straight at his enemies.
