The Raven Consort, a unique consort who does not serve the emperor despite her status, resides deep within the inner palace. Those who have seen her disagree as to whether she resembles a little girl or an elderly woman. Stories claim that she uses enigmatic arts and is capable of completing any task, from casting death spells to locating missing items. With that goal in mind, Koushun, the present emperor, travels to the Raven Consort without realizing that their destined meeting will lead to a taboo that will change the course of history.
