Ma ga Uta Tsukai

Shiratori travels to the United States to translate and publish a new best-seller "MUSE" for their company.
The famous but anonymous author of Muse "M" appears in front of Shiratori and asks this:

"Will you please lead the story I'm about to tell into a tragic conclusion?"

Than M begins to tell a tale, a strange love story involving a king, a slave girl, and a poet imprisoned in a tower.
