About Kusuriya no Hitorigoto

Kusuriya no Hitorigoto (The Apothecary Diaries) is a mystery light novel series by Hinata Natsu, published under Imagica Infos’s Hero Bunko imprint, with cumulative worldwide sales across all formats now exceeding 57 million copies. Set in an imperial court, the story follows Maomao, a sharp-witted young woman serving as a poison taster, as she unravels a series of baffling cases. Its blend of genuine mystery, exotic world-building, and compelling human drama has earned the series a devoted fanbase of all ages both in Japan and internationally.

The anime adaptation’s first season aired from October 2023 to March 2024, followed by a second season from January to July 2025. A third season is in the works, shifting the setting from the inner palace to the outside world and bringing new trials for Maomao and Jinshi.
