The Apothecary Diaries: The False Imperial Brother Launches March 18, 2027

The Apothecary Diaries: The False Imperial Brother will launch on March 18, 2027, bringing Maomao's investigation skills to consoles and PC for the first time. Koei Tecmo America, developer Gust, and TOHO Co., Ltd. have confirmed the game for Nintendo Switch 2, Nintendo Switch, PlayStation 5, and PC through Steam.

Pre-orders are now open, alongside a new overview of how this mystery-driven adaptation will work. Players will follow the sharp-eyed apothecary Maomao as she investigates a case involving the Five Mysteries and the Five Curses. The game will place its story within the imperial court setting familiar to fans, while introducing an original game-specific mystery and several new characters devised by series author Hyuganatsu.

Rather than restricting every investigation to Maomao alone, The False Imperial Brother will ask players to use the distinct talents of multiple playable characters. Maomao remains the central figure, but Jinshi and Maomao in cat form will also be controllable at selected moments. Their differing access to people and places is intended to shape how clues are discovered throughout the adventure.

A new mystery for Maomao to solve

The game's story centers on Maomao's attempts to expose the truth behind the Five Mysteries and resolve the Five Curses. That premise gives Gust room to build a case that suits the franchise's mix of court intrigue, medicine, poison knowledge, gossip, and close observation. Maomao's ability to notice details that others dismiss will naturally be central to the investigation, but the announced mechanics suggest players will need more than one perspective to uncover every lead.

Three newly created characters will appear in the game. Yanxi is described as a high-ranking official in the rear palace's Bureau of Court Etiquette. Guanyu is a travelling actor, while Chenhan is known as a regular customer of the Verdigris House. Their roles in the case, motivations, and relationships with the main cast have not yet been fully detailed, leaving plenty of room for players to speculate about how each could be tied to the central mysteries.

The involvement of Hyuganatsu in conceiving these characters is notable because it positions them as additions built specifically around this adaptation's story rather than simple cameos. For a franchise where social status, personal connections, and hidden incentives can be as important as physical evidence, new faces may substantially expand the list of possible suspects, witnesses, and allies.

Maomao, Jinshi, and Maomao the cat each offer different tools

Most of the game will be played as Maomao, whose expertise as an apothecary makes her an especially capable investigator when a case touches on illness, medicine, food, or suspicious substances. Still, her station in the palace can limit whom she can approach and which spaces she can enter. That is where Jinshi's playable sections come in.

Jinshi can use his social position to obtain statements from people who may be unwilling to speak openly to Maomao. This gives the game a narrative reason to shift control between the pair rather than treating character changes as a purely cosmetic feature. Certain information may only be available when Jinshi is able to ask the questions, potentially requiring players to consider who would be most effective in a given social situation.

Maomao in cat form will provide another kind of access. The cat can reach elevated locations, listen in on conversations, and collect evidence that human Maomao cannot reach. That creates opportunities for investigation sequences based on movement and observation: slipping into places where a person would be noticed, climbing toward overlooked objects, or overhearing a revealing exchange from a hidden perch.

Together, these three perspectives should make the palace and its surrounding spaces feel more layered. Maomao can interpret materials and examine clues with her scientific curiosity; Jinshi can navigate barriers created by rank and etiquette; and Maomao the cat can bypass physical obstacles. The setup fits a mystery game particularly well, since missing evidence is often not simply hidden but inaccessible for a specific reason.

Trust, quests, and side stories expand the investigation

Investigation will not be limited to the main plot. Players can interact with characters through quests and by supplying items they have requested, including medicines. Helping characters in this way raises their trust, and stronger relationships unlock special side stories.

That system should give players an incentive to pay attention to the people around them even when a request appears separate from the Five Mysteries. Delivering a needed remedy is a fitting activity for Maomao, whose practical medical knowledge is one of her defining strengths. It also provides a potentially meaningful use for resources and ingredients beyond the main case.

The side-story rewards suggest that relationship building will be more than a checklist of optional tasks. Players who invest in the cast can expect extra narrative material, which may offer quieter character moments amid the larger conspiracy. The announcement does not specify whether trust levels will affect the main storyline or its conclusion, so that remains unknown, but the system clearly creates an additional reason to explore requests and seek out the needs of individual characters.

Medicine-making includes difficulty options through character selection

Concocting medicine will also be a playable activity, with the Quack Doctor and Luomen joining the available roles for these sequences. The character selected for medicine-making affects the difficulty of the associated mini-games.

This is an interesting use of the supporting cast because it connects their identities and expertise directly to the game's mechanical structure. Players may be able to choose a route that better matches their comfort level with mini-games, while the character choices also reinforce the series' focus on the practice of medicine. No detailed explanation of the mini-games has been announced yet, so it is not clear whether they will emphasize ingredient selection, timing, observation, mixing procedures, or another form of challenge.

Even so, medicine preparation is a natural complement to the detective work. In the world of The Apothecary Diaries, a remedy can be a kindness, a clue, a test of expertise, or an important part of identifying what caused a victim's symptoms. Integrating that process into gameplay should help the adaptation distinguish itself from a more conventional visual-novel-style mystery structure.

Completion Stamps reward thorough players

Each chapter will include Completion Stamps for players to earn. Collecting all of the stamps will unlock special illustrations, giving completion-minded players a clear extra goal beyond reaching the story's ending.

The announcement has not explained every activity tied to these stamps, but they appear positioned as a chapter-by-chapter measure of thorough progress. Given the game's quest system, multiple playable viewpoints, and medicine mini-games, players may have reasons to revisit areas, pursue character interactions, and ensure they have fully engaged with the available content before moving forward.

Special illustrations are particularly appropriate rewards for an adaptation with a strong character focus. For fans, unlocking them may provide an added reason to pursue every available stamp; for newcomers, the system offers a tangible target that encourages a more complete look at the game's mystery and side content.

Pre-order and early-purchase bonuses detailed

Players who buy a physical or digital copy before March 31, 2027 will receive the Apothecary's Starter Kit and Modest Accessory Pack as an early-purchase bonus. For digital pre-orders, that early-purchase content is included with the pre-order offering.

A separate digital pre-order bonus is available for orders placed by March 17, 2027. Those players will receive the Apothecary's Tasteful Accessory Pack. The distinction between the two offers means that digital customers who pre-order by that deadline are set to receive both the early-purchase content and the additional digital pre-order accessory pack.

There will also be a Digital Deluxe Edition. It includes the base game, a Formal costume pack for Maomao and Jinshi, a Fantasy costume pack for Maomao, and a Fashion accessory pack for Maomao the cat. The announced bonuses are cosmetic and supplementary packs; no additional story content has been listed as part of the Digital Deluxe Edition.

A 2027 debut for the franchise's console adaptation

The Apothecary Diaries: The False Imperial Brother is being presented as the franchise's first console game adaptation. Its March 18, 2027 release will arrive simultaneously across Nintendo Switch 2, Nintendo Switch, PlayStation 5, and PC via Steam, giving players several ways to enter Maomao's newest case.

The premise has the ingredients for a distinctive adaptation: a fresh court mystery, original characters connected to an established world, character-specific investigation methods, relationship-driven side stories, and hands-on medicine preparation. The remaining questions concern how the Five Mysteries are structured, how much freedom players have during investigations, and exactly how the various clue-gathering systems connect.

For now, the confirmed details point to an adventure designed around what makes Maomao compelling: intelligence, curiosity, medical expertise, and a willingness to follow a strange detail until it reveals something much larger. Players can begin preparing for that investigation now, with the full case opening on March 18, 2027.
