Using her wit and vast knowledge of medicines and poisons alike, Maomao played a pivotal role in solving a series of mysteries and conspiracies that plagued the imperial court. Having recently come to terms with the secrets of her parents, she returns to fulfill her normal duties on behalf of the emperor's highest-ranking consorts. Maomao also works alongside the eunuch Jinshi to better the consorts' many ladies-in-waiting, including helping them learn to read. However, with the arrival of a merchant caravan comes a new wave of intrigue. A pattern of strange coincidences involving the visitors and their wares unsettles Maomao, driving her to investigate the puzzling circumstances behind the convoy. As dangers from both outside and within threaten the balance between the imperial concubines, Maomao continues to utilize her cunning and medical expertise to keep the women safe from harm.

Queen Victoria of England has ordered her loyal watchdog, 13-year-old Earl Ciel Phantomhive, to investigate a series of suspicious deaths in southern Germany. Across multiple villages, all the victims have one thing in common: they had entered the so-called Werewolves' Forest right before they developed strange deformities and subsequently died. The rumors put blame on a witch's curse, the nearby villagers' firm belief based on old folklore. Unconvinced that anything truly supernatural is at play, Ciel and his contracted demonic butler, Sebastian Michaelis—along with the rest of the Phantomhive servants—come across an isolated village in the Werewolves' Forest. Its residents are only women, hostile toward the outsiders and serving a young girl with emerald eyes and bound feet, Sieglinde Green Witch Sullivan. Ciel and Sebastian investigate to uncover the truth, but as they soon fall victim to the curse themselves, it appears that there is more to the local myths than meets the eye.
