A smoldering tale of romance and revenge set in the world of the New York Times best seller Dawn of the Arcana ! Ajin boys who show signs of special abilities are conscripted to serve in the imperial palace as beast-servants--status symbols and shields for their royal masters, to be kept or discarded on a whim. When they were children, Rangetsu's twin brother Sogetsu was ripped from her arms and sent to the palace to attend Prince Tenyou as a beast-servant, where he quickly fell victim to bloody dynastic intrigues. Now in a world that promises only bitterness, Rangetsu's one hope at avenging her brother is to disguise herself as a man and find a way into the palace! After Boku's fierce attack leaves him gravely injured, Prince Kougai jumps into the fray with Rangetsu. When they finally slash their way through the battlefield and reach General Barre of Rohan, the general finishes the battle with a bang: a giant hole opens in the earth, transporting everyone--army and all--to the imperial palace!.
