The Apothecary Diaries: The False Imperial Brother game features a brand-new story conceptualised by series author Hyuuga. The game is described below:
“Two chains of strange phenomenon and conspiracies are causing chaos throughout the rear palace, red-light district, and streets of the capital. Apothecary Maomao must use every ounce of her intelligence and knowledge to solve the mysteries and unveil the truth behind the False Imperial Brother before it destroys the imperial court.”
Author Hyuuga started the original story in October 2011 on the Shousetsuka ni Narou website, and Shufunotomo began publishing the novel series with illustrations by Shino Touko in August 2014. The 16th novel in the series was released in May 2025.
J-Novel Club publishes the original novel series digitally in English under the name The Apothecary Diaries, and it released the 16th novel in May 2026. J-Novel Club describes the story below:
“In the East is a land ruled by an emperor, whose consorts and serving women live in a sprawling complex known as the hougong, the rear palace. Maomao, an unassuming girl raised in an unassuming town by her apothecary father, never imagined the rear palace would have anything to do with her—until she was kidnapped and sold into service there.
Though she looks ordinary, Maomao has a quick wit, a sharp mind, and an extensive knowledge of medicine. That’s her secret, until she encounters a resident of the palace at least as perceptive as she is: the head eunuch, Jinshi. He sees through Maomao’s façade and makes her a lady-in-waiting to none other than the Emperor’s favorite consort… so she can taste the lady’s food for poison! At her lady’s side, Maomao starts to learn about everything that goes on in the rear palace—not all of it seemly. Can she ever lead a quiet life, or will her powers of deduction and insatiable curiosity bring her ever more adventures, and ever more dangers?’
The novel series was adapted into a TV anime in October 2023, with a second season in January 2025. The anime’s third season premiered on October 2nd, 2026.

Now, she’s making a name for herself solving medical mysteries!”
