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'Âs 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'Âs one hope at avenging her brother is to disguise herself as a man and find a way into the palace! Prince Tenyou is not what Rangetsu expected, and the political currents in the palace run deep and strange. Does Rangetsu have any chance of finding justice for her brother, or will she become just another Ajin casualty in the game of kings?
