The civilization that once had prospered has now turned to a tale of dreams, as the inextinguishable flames of war tear the realm asunder.

The return of the super technology known as "Sacred Treasures" could revolutionize the world order, but no one knows of them but one person—a "heretical girl".

A girl from the Western Star, Joan Kaguya d'Arc, saw divine revelations of the birth of a "Savior King" who will save the world.

She embarks on a journey to the Eastern Star with Leonardo Da Vinci, "the one who observes the world".
