Midari ni Kaii to Kimetsukete wa Ikemasen Novel Cover

New Cover Artwork Features Miharu and a Red Umbrella

On November 4, 2026, SB Bunko revealed the cover of Midari ni Kaii to Kimetsukete wa Ikemasen, featuring artwork illustrated by Shizu Yamauchi.

The illustration depicts a long-haired woman wearing glasses and light-colored clothing beneath a large red umbrella. The character is 聖城美春, the mysterious graduate student who serves as one of the story's central figures.

Behind her, a narrow street lined with traditional buildings creates the impression of an old neighborhood after rainfall. Author Hirokazu Minemori confirmed that the location is Kuragari-zaka (暗がり坂), a historic passage in Kanazawa that has also appeared in his earlier writing.

The illustration combines an atmospheric urban setting with the character's calm yet mysterious appearance. Minemori also expressed his appreciation for Yamauchi's depiction of Miharu, praising the balance between her charm and enigmatic personality.

A Detective and a Mysterious Graduate Student Investigate Strange Cases

Midari ni Kaii to Kimetsukete wa Ikemasen follows 秋月徹郎, a detective suspended from duty following an incident connected to his work.

While visiting a hot spring area in Kanazawa affected by a mysterious disappearance, he encounters 聖城美春, a tall and intellectually gifted graduate student with extensive knowledge of supernatural folklore.

Miharu uncovers the truth behind one of the incidents while insisting that unusual events should not automatically be attributed to supernatural forces. Their encounter marks the beginning of an unconventional investigative partnership.

After the first case, Miharu continues drawing the detective into other puzzling investigations. Their contrasting personalities and interactions form an important part of a narrative that combines criminal mysteries, regional folklore, and lighthearted character dynamics.

Hokuriku Yokai Legends Form the Heart of the Mystery

One of the novel's defining features is its focus on supernatural traditions from Hokuriku, a Japanese region encompassing areas such as Ishikawa, Toyama, and Fukui.

The official synopsis references kamikakushi, mysterious disappearances traditionally associated with supernatural intervention; tsurube-otoshi, a creature from Japanese folklore; and kappa, beings commonly linked to rivers and other bodies of water.

The legend of saruoni also appears among the mysteries the characters investigate. These references give the novel a distinctly regional identity rather than relying exclusively on supernatural figures already familiar to international audiences.

Despite its occult themes, the story does not automatically establish supernatural forces as the cause of every incident. Instead, the title emphasizes investigating unusual events before drawing conclusions, placing the relationship between folklore and evidence at the center of its mystery approach.

Hirokazu Minemori Draws on His Research into Kanazawa Folklore

Author Hirokazu Minemori describes the book as a light mystery built around connected cases and informed by his knowledge of local folklore.

Minemori previously wrote stories set in Kanazawa, including Kanazawa Koyouguya Kuragaridou and Shounen Izumikyouka no Meiji Kidanroku. His interest in Ishikawa's supernatural traditions has also developed through research and nonfiction writing.

He compiled Kanazawa Youkai Jiten, a reference work on yokai legends from Kanazawa, and contributed columns discussing folklore and unexplained phenomena in Ishikawa. According to the author, the knowledge collected through those projects directly informed his latest novel.

Minemori also explained that the novel's title can be abbreviated as "み怪決", a playful expression that sounds like "未解決" (mikaiketsu), meaning unresolved. The wordplay reflects the story's relatively lighthearted approach to mystery, including room for humor between its protagonists.

November 26 Release as Part of the New SB Bunko Imprint

The novel will be published under SB Bunko, an entertainment fiction imprint launched by SB Creative in October 2026.

The imprint publishes several categories of fiction, including light mysteries, horror, coming-of-age stories, romance, and fantasy. Midari ni Kaii to Kimetsukete wa Ikemasen is among its November 2026 releases.

According to the publisher's current official product listing, the novel is scheduled for Thursday, November 26, 2026, with a retail price of 902 yen including tax, a bunkobon paperback format, and 336 pages. Its ISBN is 978-4-8156-4819-0.

Earlier information differs in two places: an October blog post by the author referenced November 25, while an older publisher press release listed 858 yen. This article uses November 26 and 902 yen, based on the latest official product listing.

Why This Matters

1) Regional folklore gives the mysteries a distinct identity

The inclusion of kamikakushi, tsurube-otoshi, kappa, and saruoni grounds the story in local traditions. Readers can explore unexplained incidents while encountering folklore associated with the Hokuriku region.

2) The cover connects the fiction to a real location

Kuragari-zaka is more than a generic traditional street used for atmosphere. Its inclusion connects the cover directly to Minemori's familiarity with Kanazawa and his previous writing, adding a recognizable location to the artwork.

3) The story questions supernatural assumptions

The title itself suggests how the protagonists approach their investigations. Folklore becomes part of the mystery, but understanding what truly happened remains essential before accepting a supernatural explanation.
