"Maomao no Hitorigoto" is set in an imperial court of an unnamed ancient East Asian-inspired empire, where the protagonist, Maomao, a young apothecary, becomes entangled in the intrigues of the palace. Initially sold into servitude at the rear palace, where the emperor’s concubines reside, Maomao uses her sharp intellect, keen observational skills, and extensive knowledge of medicine and poisons to navigate the dangerous political landscape.
