What stands out at first glance about My Dear Detective: Mitsuko’s Case Files is the stylish cover design. Two elegantly dressed individuals in a traditional tea salon immediately convey a sense of atmosphere and era. That’s how I first came across the series a few years ago when it launched on Azuki - a subscription platform. But behind this aesthetic facade lies more than a beautifully illustrated historical mystery.

My Dear Detective: Mitsuko’s Case Files was written and illustrated by Natsumi Ito and debuted on May 18, 2021, in the seinen magazine Manga Action published by Futabasha. The magazine serialization ended on May 21, 2024, and since October 18, 2024, the series has continued digitally on the Web Comic Action platform.

The English translation has been available digitally via the Azuki app since 2022. A print edition has been published by U.S. publisher Seven Seas since October 2024.

What is My Dear Detective: Mitsuko's Case Files Vol. 1 About?

The story begins in 1926, a time of transformation in Japan as the country gradually opened itself to Western influences. This cultural and social shift is evident not only in fashion and architecture but also in the reevaluation of traditional gender roles. The main character, Mitsuko Hoshino, exemplifies this change. As a private detective, she works in a male-dominated field and must contend not only with criminal cases but also with everyday sexism. Offensive graffiti on her agency door and disparaging remarks from those around her show that equality is still a distant goal. Nevertheless, Mitsuko faces these challenges with intelligence, composure, and remarkable resolve.

She is supported by Saku Yoshida, a young man who first appears as a café waiter and soon turns out to be the son of a wealthy businessman. Over the course of the story, he becomes Mitsuko’s assistant in her investigations. A respectful and nuanced relationship develops between the two, characterized by mutual trust, subtle tension, and humorous moments. Despite his prominent role, Saku always remains at Mitsuko’s side without undermining her independence.

Their dynamic is strongly reminiscent of the characters Jo and Laurie from Greta Gerwig’s Little Women, as the mangaka herself has noted. Saku brings a certain youthful naivety that complements Mitsuko’s determined nature perfectly. It’s especially refreshing that while he supports her, he never overshadows her as the main character.

Content-wise, the first volume presents several smaller cases that are far from trivial in theme. Topics include transgender identity, forced marriage, and female artists working under male pseudonyms. These issues are surprisingly current and are presented with respect and clarity. While the cases are simply structured and often resolved quickly, they serve more as an introduction to Mitsuko’s world and as a lens through which to explore societal issues. Fans of coherent mysteries will also be satisfied - and I count myself among them. I simply don’t enjoy how in many mystery stories the culprit is revealed with a sudden twist that’s hard to follow.

The storytelling is calm but never dull. The manga avoids artificial drama and instead excels through subtle nuances - a fitting approach that complements the quiet strength of its main character.

The narrative is calm and composed, yet never tedious. Instead of excessive drama, the manga relies on delicate nuances and understated presentation that align well with the protagonist’s demeanor. Visually, the volume also impresses. Natsumi Ito’s art style is delicate and detailed, especially when it comes to historical costumes and carefully rendered settings. The panel layout is clear, and the reading flow is smooth without sacrificing depth.

Especially well-done is the balance between realistic depiction of the time period (including socio-historical details) and a certain artistic freedom. Even if there are minor inaccuracies - such as the premature mention of Bonnie and Clyde - they barely detract from the overall impression.

Is My Dear Detective: Mitsuko's Case Files Vol. 1 Worth Reading?

My Dear Detective: Mitsuko’s Case Files offers a compelling entry into a historical crime series with a feminist perspective. The manga combines stylish design with socially relevant themes and a strong, convincingly portrayed protagonist. The criminal cases are more subdued and simple but provide an effective framework for a nuanced exploration of the era. While the mysteries themselves are gentle and straightforward, they serve as the perfect stage for a character like Mitsuko.
