Hiromu Arakawa, award-winning manga creator of the best-selling smash hit Fullmetal Alchemist, draws readers into an intricate new web of magic, intrigue, and life-or-death stakes! In a world where certain humans command mighty supernatural duos called Daemons, it is the birthright of "the children who sunder day and night"--twins Yuru and Asa--to rule over these powerful entities. 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!! Having infiltrated Higashi Village and taken two of its residents hostage, Ivan beckons Yuru to a warehouse in the dead of night. Although Yuru stakes out the location from a distance, he's swiftly kidnapped by a skull-faced Daemon under Asuma's command. The Divine Guardians are left to fend for themselves as the familiar scents of Yuru and Asa's parents waft from Ivan's blood-soaked blades...
