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。。。

Deep in the mountains， under the watchful eyes of two stone guardians， lies isolated Higashi Village。 Unlike some of its residents， young Yuru is content to live out his days foraging and hunting in the nearby woods。

But Yuru's idyllic life changes forever when Higashi Village comes under attack。 Amid the chaos， the young man is whisked away and forbidden to return to the only home and family he's ever known。 And to ensure his safety， the two statues who once stood guard over the village have joined the fight--the Divine Left and Right！

As Yuru soon discovers， commanding these Daemons is his birthright。。。 But after losing everything dear to him， will he be up to the task of unraveling a conspiracy tying him and his twin， Asa， to a prophecy that threatens the entire world？
