RG Veda Volume 4

The party of Yasha, Ashura, and Ryuu-ou arrives in the Northland, where the Yasha village used to be. Vahyu and his army were sent from Koumokuten, and attack the party but soon retreat. It was Taishakuten's trap to lure the party towards the north-end of the land, where there is a monster that lives in an ice castle. The party spends the night at a fort that used to be used by Yasha tribe, and a strange butterfly visits Ashura's dream. The butterfly appears in the real world as well, and starts multiplying. They surround Ashura and Yasha, and take Yasha away with them. To save Yasha, Kujaku shows the way to the ice castle to Ashura and Ryuu-ou. Vahyu comes back and attacks them. Souma arrives with the Shura Sword in her hands, and while the others are fighting Vahyu and the monsters, Kujaku performs the ceremony of the Shura Sword's succession for Ashura. "Dark Ashura" appears and destroys Vahyu and his army. With the power of the Shura Sword, they break the shield and enter the ice castle. Ashura finds Yasha, and they all escape from the castle. Kujaku is left in the castle, and shows the monster his wings before he kills it.
