Mononoke The Movie: Chapter II - The Ashes of Rage

A month after the events of Mononoke The Movie: The Phantom in the Rain, the mysterious man known only as the "Medicine Seller" returns to the imperial harem. While things appear markedly improved thanks to Asa's management of the lower rank concubines, the infighting amongst the upper ranks is about to reach its climax. As the top concubines fight a battle of words and sexual seduction to produce the next imperial heir—and their fathers use them as pawns in their backroom political dealings—one of the women in the harem spontaneously combusts, marking the start of a new mononoke threat.
