Within the royal court, there exists a figure both feared and revered: the Raven Consort, Ryuu Jusetsu. Living in her jet-black palace and cut off from the emperor, she is the subject of endless rumors. Alleged to hold mystic powers, she is said to accept any request—ranging from locating lost objects to casting curses. While some label her an immortal sage, others view her as a terrifying revenant. Yet such remarks do not bother Jusetsu, who prefers to spend her days in quiet solitude. That changes when the emperor, Ka Koushun, bursts into her court and asks for her help with a mysterious case. The young emperor's request forces Jusetsu to leave her palace for the first time. Although Ka Koushun's frequent visits annoy her greatly, she cannot bring herself to refuse him. Her predecessor's teachings echo in her mind: the Raven Consort is destined to remain forever alone and never desire anything. However, Jusetsu finds herself forming the first of several bonds when she asks Jiujiu, an innocently curious court girl, to serve as her sole attendant. Together, they begin fulfilling requests from the palace inhabitants. However, unknown dangers lurk in the outside world, and drawing attention to herself may force Jusetsu to confront a past that is better left undisturbed.
