Episodes 13-16 of Kazuhiro Furuhashi's modern anime classic set in France in the time of Louis XV. The politics of dancing have never been more deadly. After meeting with the Russian royalty, D'Eon and his comrades find themselves in the Empress's favour. Yet she has partners who want to cut in, cut them out, and cut her throat. As the tempo of this political waltz speeds up, darker and more dangerous missteps are made. Secret sorcerers show their true faces and powerful players make desperate moves. D'Eon will at last come face-to-face with the traitor to his cause and, quite possibly, the one responsible for his sister Lia's demise.
