Mariya Ise Joins as the Mystery Boy Muchin
Mariya Ise (Killua Zoldyck in Hunter x Hunter, Serie in Frieren: Beyond Journey's End, Himeno in Chainsaw Man) voices Muchin (沐清), a new character created for the film. He's a boy from the family that governs the bustling water city in the south where most of the movie takes place, and the announcement bills him as the character holding the key to the whole story. His one moment in the trailer is not reassuring: a frightened face and a plea of "please help me." How he connects to Maomao and Jinshi is still under wraps, and no official English romanization of his name has been confirmed yet; some English outlets render it Mu Qing.
A Consort Who Died Five Years Ago, and a Body That Never Decayed
According to the announcement covered by Japanese anime news site Anime Anime, the film's full title is Gekijōban Kusuriya no Hitorigoto: Bōhi no Hihō (劇場版 薬屋のひとりごと 亡妃の秘宝). There's no official English subtitle yet; it translates roughly to "The Late Consort's Secret Treasure," and the story is a completely original one written by series author Natsu Hyūga rather than an adaptation of an existing arc.
The setup: the Emperor orders Jinshi to grant the dying wish of a consort who passed away in the rear palace five years ago, which was to be returned home to her family. When her body is recovered for the journey, it looks as though she's merely sleeping, untouched by five years of decay. To get to the bottom of that impossibility, Maomao joins Jinshi on the trip south to the consort's homeland, a lively city built on the water. Maomao, naturally, is more excited about the unfamiliar medicines and plants than the funeral. But the region has problems of its own. Pirates are running wild over a treasure supposedly hidden by the area's previous head, and on the day of the consort's funeral, a major incident sends everything spiraling.
In its latter half, the new trailer, up now on the TOHO animation YouTube channel, shows Maomao wondering aloud what secret the dead woman could be hiding. The teaser visual plays up the treasure-hunt side of the premise: Maomao's torch lighting up a cave full of treasure while fire arrows rain down on a burning shore in the distance, under the tagline "That mystery leads to the hidden treasure."
Returning Cast, Returning Staff, New Travel Clothes
Aoi Yūki is back as Maomao and Takeo Ōtsuka as Jinshi, and both got new character visuals in movie-original outfits. Maomao keeps her trademark green with her arms crossed and a sharp look aimed straight at the viewer, while Jinshi trades his usual palace wear for a noble travel outfit in deep blue.
Behind the camera, it's the TV series' core team. Norihiro Naganuma directs from a screenplay by Yuko Kakihara, with Yukiko Nakatani handling character designs and serving as chief animation director. The music comes from the trio of Satoru Kōsaki, Kevin Penkin, and Arisa Okehazama, and TOHO animation STUDIO produces the animation, with Toho distributing.
The film arrives in the middle of a big stretch for the franchise, whose novels and manga have passed 45 million copies in circulation. Season 3 of the TV anime starts in October 2026 as a split-cour broadcast, and the movie lands just two months into it.
Looking Ahead
Bōhi no Hihō opens in Japanese theaters on Friday, December 11, 2026. No international theatrical or streaming release has been announced yet. Crunchyroll streamed the first two seasons and their English dubs, so a similar arrangement would be the obvious path for the film, but nothing is confirmed. Anime News Network reports that Season 3's second cour follows in April 2027, so the franchise will be running more or less continuously from this fall through next spring.
For readers who want to catch up on the source material, J-Novel Club publishes Natsu Hyūga's light novels digitally in English, and Square Enix Manga & Books handles the print editions of both the novels and the manga adaptation. Since the film is an original story, though, there's nothing to spoil: everyone walks into the theater blind on this one.
