Koukyuu no Karasu

Deep within the inner palace lives a special consort who does not serve the emperor despite her position, known as the Raven Consort. People who have seen her say she looks like an old woman, while others say she looks like a young girl. Stories talk of her use of mysterious arts and how she can take on any request, be it death curses to finding lost things. Koushun, the current emperor, goes to visit the Raven Consort with that intention, without knowing that their fated meeting will become a taboo that will overturn history.
