Manga adaptation launched in November 2019
The November issue of Ichijinsha‘s Monthly Comic Zero-Sum magazine revealed on Tuesday that Akatsuki’s manga adaptation of Nanako Tsujimura‘s Hōsekisho Richard-shi no Nazo Kantei (The case files of Jeweler Richard or literally, The Mystery Appraisals of Mr. Richard the Jeweler) novel series has ended its current arc, and will take a two-issue hiatus before beginning its new arc in the magazine’s February 2022 issue on December 28.
The “heartwarming jewel mystery” series centers on the handsome jewelry appraiser Richard Ranashinha Dvorpian and the bright and cheerful college student Seigi Nakata as they uncover the hidden messages that lie within jewels.
Akatsuki launched the manga adaptation in Monthly Comic Zero-Sum in November 2019. Ichijinsha published the manga’s third compiled book volume on February 25.
Tsujimura launched the novel series with the first volume in 2015 under the Shueisha Orange Bunko imprint. The series’ 11th volume shipped on June 28. Utako Yukihiro (Devils and Realist, Uta no Prince Sama, B-PROJECT) illustrates the series.
The novels inspired a television anime adaptation that premiered in January 2020. Crunchyroll streamed the series as it aired in Japan.
