Short version: Shinwa no Misshitsu (“The Locked Room of Myth”) treats the locked room as closure of thought rather than of space. Readers who want a pure logic puzzle may find it does not fit.
A remote mountain village, a sealed space, the words myth and curse. Starting it, my first thought was “this may be a story where unexplained unease accumulates ahead of any reasoning.”
Despite following the series as medical mystery, the air was different from the start, with the pressure of place and folklore stronger than logic. Reading on, the device of the locked room and the vagueness of myth turn out to sit far closer together than expected.

What kind of book is it?
The twelfth volume of the Ameku Takao series, and a short story collection — magazine stories plus new material.

| Author | Mikito Chinen |
| Imprint | Jitsugyo no Nihon Sha Bunko |
| Released | March 7, 2024 |

“Suiri Karute” against “Jiken Karute”
The subtitle decides how a volume reads. Not knowing this makes the differences between volumes confusing.
| Subtitle | Format | How it reads |
|---|---|---|
| Suiri Karute | Short stories | Each case resolves in one story. Easy to read in short sittings |
| Jiken Karute | Novel | One case followed to the end. Sustained tension |
“Suiri Karute” volumes collect magazine stories with new material added; “Jiken Karute” volumes are novels written directly for paperback. They alternate, so reading in publication order alternates between short stories and novels.
Characters and setting
| Takao Ameku (27) | Deputy director and head of the General Diagnostics Department. She has Asperger’s syndrome and savant traits, and diagnoses through extraordinary recall and calculation |
|---|---|
| Yu Takanashi (29) | The narrator. A former surgeon reassigned to General Diagnostics as a trainee internist |
| Mai Konoike (25) | A resident who admires Takao |
| General Diagnostics | Founded by Takao’s father to resolve undiagnosable patients and inexplicable incidents through diagnosis. It occupies a single-storey red brick building on the hospital roof |
Narrating through Takanashi rather than Takao is what keeps the series readable. The reader watches Takao from Takanashi’s position, so her strangeness never lands directly.
The series had passed 3.9 million copies as of May 2026, and a TV anime aired from January 2 to April 3, 2025 (produced by project No.9). The author, Mikito Chinen, was born in Okinawa in 1978, trained as an internist at Jikei University School of Medicine, and has been nominated four times for the Japan Booksellers’ Award.
Stepping into a remote village
The setting is a mountain village at a distance from the outside world. In a series where cases usually occur in cities or hospitals, that closed setting stands out.
With every page, “the usual standards may not apply here” grows stronger. The values the villagers share, and the myth spoken of as a matter of course, destabilize the reader’s footing before any reasoning begins.
The locked room itself reads not as a precondition for a trick but as something placed to emphasize the absence of escape. Not only the space is closed — the available ways of thinking and explaining narrow too.

Myth spoken before the case
Myth and curse are narrated before the incident. My reading slowed here; I could not immediately tell whether this was background or a load-bearing element.
Reading on, the myth functions not as a question of belief but as an indication of the premises through which the people who live here see the world.
More than whether something can be explained rationally, the history and atmosphere accepted as “that is how it is” shape how the incident is received.
Myth placed as a foundation that distorts human judgment, rather than as mystery decoration, is what caught me most.
The distance from the word “locked room”
The title had me expecting a more legible, puzzle-shaped structure.
In practice, the locked room is written far more around “how will it be received” than “can it be solved”.
The moment what happened in the locked room is tied to myth and curse, the direction of explanation narrows sharply. Reading that, I repeatedly thought “perhaps no other possibility was ever on the table.”
Logical interpretation is not excluded, and the atmosphere pushes it down the queue. That frustration is what holds the tension.

Where Takao is placed
Her position looks different here. As rational and medically grounded as ever, her view repeatedly fails to mesh with the air of the village.
It is less that her words do not land than that “another answer has already been prepared before they can”.
Not a failure of ability but a misalignment of premises. And because that misalignment is so explicit, her outline as a character is thrown into relief.
What remained
| A good fit | May not fit |
|---|---|
| Readers drawn to the locked room as closed thinking | Readers who want a pure logic puzzle |
| Readers interested in place constraining judgment | Readers who want a clean sense of resolution |
| Readers who like local folklore in a case | Readers expecting a hospital-bound story |
Afterwards I found myself asking “was this resolved, or merely organized?” That the question stays open is itself what characterizes the volume.
