In the world of flying crow-humans, trouble is brewing... YUKIYA is the lackluster second son of a regional boss in the North House territory. His younger brother has overtaken him in academics. He is no good at sword battle, either. Not that this ever bothers him. So it comes as a shock when this boy, who claims to have no ambition whatsoever, is the one chosen to attend the Imperial Prince in Court--. What awaits YUKIYA and his new master is intrigue, murder, a mysterious drug, and invasion from an unexpected enemy. Can they save the world of Yatagarasu (three-legged crows of Japanese myth)?
