Description

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!!

To get some answers, Yuru warily accepts an invitation from the Kagemoris, the very people who assaulted his village. This soon turns into an uneasy alliance when an ambush threatens everyone's safety. But not even that surprise can prepare Yuru for Asa's story! What is the stark secret to claiming the twins' powers? And does Yuru have what it takes to confront what lies in the abyss...and beyond?
