Sōtō no Sōryūha

"Remember this well, Towa. Your attack, the Azure Dragon Wave, was created by Sesshōmaru. But you have made it your own by giving the dragon twin heads.From this day forward, you shall call it the "Twin Azure Dragon Wave"."

- Kirinmaru to Towa

is the improved form of Sesshōmaru's attack, Sōryūha that was used Towa Higurashi. A powerful burst of yōki is released and takes the form of a two-headed dragon. It draws its energy directly from Towa, and varies in strength. She first utilizes this move against Kirinmaru after he had slain Towa's sister, Setsuna.
