There are detective games built around gavels, courtroom interruptions, and the sacred right to yell when somebody’s testimony turns wobbly. Then there are detective games where a wrong inference may need to survive the gaze of the emperor. The Apothecary Diaries: The False Imperial Brother appears to be firmly in the latter camp, and that is an extremely compelling place for an investigation game to be.
Koei Tecmo has revealed the new game, which is scheduled for early 2027 on PlayStation 5, Nintendo Switch 2, and Steam. Its setup places series leads Mao Mao and Jinshi in an original mystery intended to send them through the palace’s most guarded spaces, rather than simply retell an existing storyline. For fans who have wanted a game that understands the core appeal of The Apothecary Diaries is not merely pretty robes and ominous corridors, but the joy of watching Mao Mao dismantle a mystery through alarming medical curiosity, that premise is a very promising prescription.
An original palace case for Mao Mao and Jinshi
The game’s story is planned by Hyuganatsu, creator of the series. Mao Mao and Jinshi will investigate a case called “The Five Mysteries of the Rear Palace.” That immediately sounds suited to the setting: a dense web of protocol, status, rumors, illness, favors, rivalries, and things people very much prefer to keep off the record.
At the center is Mao Mao, the apothecary whose extensive knowledge of medicine, toxins, symptoms, and ingredients has repeatedly made her a uniquely effective investigator. She is brought into service as a poison taster within the Imperial harem, a job that is already a fairly emphatic declaration that lunch could become a side quest at any moment. Her ability to spot a strange detail, connect it to a substance or condition, and follow that clue toward a human motive is what gives the series its distinctive detective flavor.
Jinshi, the imperial eunuch who works alongside Mao Mao, is also part of the game’s investigation. Their partnership is important because the two bring very different access and perspectives to palace problems. Mao Mao has the observational rigor and pharmaceutical expertise; Jinshi has standing, resources, and a personal interest in keeping an increasingly complicated palace from becoming even more complicated. The game’s announced structure gives that partnership room to do actual investigative work rather than merely appear in a cutscene and stare meaningfully across a decorative screen.
The casework sounds pleasingly familiar
The False Imperial Brother is described as a mystery-focused adventure with a structure that recalls courtroom-and-investigation games such as Ace Attorney. Mao Mao and Jinshi will examine crime scenes, speak with people connected to each incident, and assemble an explanation for what occurred. Instead of presenting that theory to a judge, however, they will offer their deductions before the emperor.
That distinction matters. A courtroom game is inherently theatrical: witnesses can be challenged, evidence can be brandished, and legal procedure becomes the arena for discovering the truth. A Rear Palace inquiry should have a different kind of pressure. Court etiquette, hierarchy, and the potential consequences of embarrassing someone powerful could turn each conclusion into a delicate operation. Mao Mao may know precisely what a symptom means, but communicating that answer in the wrong way could be its own problem.
Nothing announced so far guarantees an elaborate accusation system, branching verdicts, or a direct one-to-one mechanical imitation of any specific detective series. Still, the listed loop is clear enough to set expectations: investigate, interview, collect information, and make a reasoned case. That is a natural fit for a property whose mysteries often hinge on practical details that other people overlook.

The game’s premise is not about becoming the greatest warrior in the palace. It is about being the person who notices that the tea, the cosmetics, the food, the medicine, or the story someone is telling does not quite add up.
Exploration, gathering, and crafting expand the apothecary angle
Investigation is only one part of the announced feature set. The game also includes exploration, gathering, and crafting. Those systems make immediate thematic sense for Mao Mao. An apothecary should not feel detached from the materials that make her deductions possible; plants, remedies, compounds, and other useful items are central to her worldview.
Exploration could also help make the Rear Palace feel like more than a backdrop between conversations. In this setting, a corridor, garden, room, kitchen, or storage area can carry as much narrative weight as a formal audience chamber. Where an item was found, who can reach a particular area, and what grows or is stored nearby are the kinds of seemingly ordinary facts that can become decisive in a Mao Mao mystery.
Gathering and crafting likewise have room to support the detective work without turning the game into a generic ingredient checklist. The available information does not specify exactly how crafting will work or which materials can be collected, so it is too early to assume recipes, gear systems, or the scale of the exploration. But the high-level idea is sound: knowledge of substances is Mao Mao’s superpower, even if it comes packaged with an enthusiasm for poison that most palace HR departments would probably flag.
Why this series is such a strong match for a game
Adaptations often face the difficult task of identifying what audiences actually come to a series for. With The Apothecary Diaries, the answer is not just mystery in the abstract. Its appeal lies in the way medical knowledge, social tension, and character comedy are woven together. Mao Mao does not investigate from a spotless detective office with a corkboard and a tragic saxophone loop. She works within a world where access to information is tightly controlled, appearances are political, and a minor ailment can conceal something much larger.
A game can give players more time to sit with that process. Examining a location, deciding whom to speak to, gathering materials, and moving from clue to hypothesis all seem capable of translating the series’ rhythm into interactive form. It is an especially attractive alternative for players who miss the deliberate cadence of visual-novel-style mystery games: less about reflexes, more about whether the story is giving you enough fragments to understand the whole picture.
The emperor-facing deduction segments may also create the necessary dramatic payoff. A mystery needs a moment when scattered observations stop being separate curiosities and become an answer. The palace setting gives that answer additional stakes, because status and secrecy can be as dangerous as whatever substance Mao Mao has identified.
A 2027 release, with three major platforms confirmed
The Apothecary Diaries: The False Imperial Brother is currently planned for early 2027 on PS5, Switch 2, and Steam. No further release specifics are established in the available details, so players should treat the early-2027 window as the key date rather than assume a precise launch day, physical edition, or additional platform release.
The Switch 2 version joins a growing list of games announced for Nintendo’s newer hardware. For more on another title confirmed to use a physical Switch 2 release, see Stellar Blade: Complete Edition’s Switch 2 cartridge plans.
The timing also lands alongside continued momentum for the anime itself, with season three expected to begin in October 2026. That leaves a substantial gap between the show’s next chapter and the game’s early-2027 arrival, but it also gives the new original story space to stand on its own rather than feel like a hurried companion piece.
What has not been detailed yet
There is plenty still to learn. The announcement confirms the premise, the main pair, the central case name, investigation activities, exploration, gathering, crafting, the platforms, and the early-2027 release window. It does not yet establish the game’s exact structure, how long it will be, whether investigations use choices or item-based contradiction mechanics, or how much of the palace can be freely explored.
That uncertainty is not a drawback at this stage; it simply means the most useful expectation is a focused one. This is an original Mao Mao and Jinshi mystery built around the Rear Palace, where clues must be found, people must be questioned, and a convincing explanation must be delivered at the highest possible level. If the game captures the satisfaction of discovering that a tiny botanical, culinary, or medical detail changes the entire case, it could give detective-game fans a palace full of reasons to keep looking closer.
