One month after the Karakasa disaster, life in the Inner Chambers is gradually easing back to normal. For the aristocratic houses that govern the realm, stability simply means resuming their long‑standing plots to forestall any unwanted shifts in power. Their present focus is the senior concubine Fuki Tokita, who appears to be attracting Lord Tenshi"s favor even though she is the daughter of a merchant and thus deemed unsuitable to bear him an heir. The tension among the nobles rises as they anticipate any move that could upset their delicate balance.
Yet unseen supernatural powers linger in the shadows. When a series of unnatural deaths occur within the Inner Chambers, its inhabitants are compelled once more to welcome the enigmatic Medicine Seller into their precincts. Only this trader can uncover the root of these tragedies—and discover Fuki"s involvement.
