Separated from a young age and unaware of the truth of their birth, brother and sister must fight to make their way back to each other, claim their birthright, and save the world... Ancient Daemons awaken to fight a new battle in an age-old war!! A debilitated Akio explains his reasons for betraying the Kagemori clan to a bewildered Natsuki. Shortly thereafter, Mountain God's relics explode, allowing Akio to escape captivity and join his new companions, an enigmatic group of Daemon Wielders from western Japan. On the other side of town, Hana is summoned to a secret meeting of Higashi Village agents, where the same group is poised to launch another terrorist attack.
