{{nihongo|Layton Mystery Detective Agency: Katri's Puzzle Solving Files|レイトン ミステリー探偵社 ~カトリーのナゾトキファイル~|Reiton Misuterī Tantei-sha ~Katorī no Nazotoki Fairu~||lead=yes}} is an anime television series produced by Liden Films. Centering around characters from Level-5's 2017 video game, Layton's Mystery Journey, part of the Professor Layton franchise, the series began airing on Fuji TV's Adventure Sunday programming block from April 8, 2018 and concluded on March 31, 2019. Novelisations of episodes 1–9 and 11–13 were published by Shōgakukan's Junior Bunko in four three-case installments.

Plot

Taking place after the events of Millionaires' Conspiracy, the series follows Katrielle "Katri" Layton, daughter of the renowned Professor Hershel Layton, who has set up the Layton Detective Agency alongside her self-appointed assistant, Ernest Greeves, and taken on a client-in-residence in the form of an amnesiac talking dog she dubs Sherl. Together, the trio take on all kinds of requests to solve mysterious cases troubling their fellow Britons.

Cast

The anime features an all-new main cast.{{Cite web|url=https://www.animenewsnetwork.com/news/2018-05-31/layton-mystery-tanteisha-anime-casts-soma-saito-streams-3rd-video/.132265|title = Layton Mystery Tanteisha Anime Casts Sōma Saitō, Streams 3rd Video}}

  • Kana Hanazawa as Katrielle "Katri" Layton – A quirky and enthusiastic young detective who aims to solve any case, no matter how strange.
  • Jūrōta Kosugi as Sherlo / Sherl – A talking dog adopted by Katrielle, who can only be understood by a select few.
  • Kyōsuke Ikeda as Noah Montol / Ernest Greeves – Katrielle's devoted and mildly infatuated assistant at the Agency.
  • Yōhei Tadano as Darjeeling Aspoirot / Ercule Hastings – A police detective who often requests Katrielle's aid.
  • Hibiku Yamamura as Geraldine Royer / Emiliana Perfetti – A police profiler and investigative rival of Katrielle.
  • Koichi Yamadera as Professor Hershel Layton – A legendary puzzle-solving archaeologist and father to Katrielle, who mysteriously disappeared when she was a child.
  • Soma Saito as Luke Triton – The Professor's faithful assistant from many years ago.

Other roles are retained by the original game cast, with the exception of a minor role occupied by Tadano, which was recast. The passing of Tetsuo Gotō on November 6, 2018 necessitated the recasting of his character, previously featured in the series' 28th episode, for episodes 47 and 48.

Production

The series was first officially revealed in December 2017, following a previous report that a Professor Layton anime was in production.{{Cite news|url=https://www.animenewsnetwork.com/news/2017-10-03/licensing-magazine-professor-layton-tv-series-in-development/.122224|title=Licensing Magazine: Professor Layton TV Series in Development|work=Anime News Network|access-date=2018-03-09|language=en}}{{Cite web|url=https://lastteabreak.hatenadiary.jp/archive/2017/10/05|title=2017-10-05から1日間の記事一覧|date=5 October 2017 }} The 50-episode series is produced by Liden Films and directed by Susumu Mitsunaka, animation director of the original game, with creative direction and series composition by series creator Akihiro Hino, music by series stalwart Tomohito Nishiura, and character design by Yoko Takada, based in part on Takuzō Nagano's original designs.

The series began airing in Japan on April 8, 2018, as part of Fuji TV's Adventure Sunday programming block. Bomanbridge Media have distribution rights to the series in other Asian territories.{{Cite web|url=https://www.animenewsnetwork.com/news/2017-12-28/layton-games-get-spring-tv-anime-starring-professor-daughter/.125829|title=Layton Games Get Spring TV Anime Starring Professor's Daughter}} It features adaptations of the twelve cases from the original game with new story elements, alongside a large number of original standalone mysteries and an all-new story arc featuring originating series protagonists Professor Hershel Layton and Luke Triton. Many episodes pay homage to a diverse array of popular media properties, making pastiche of Panty & Stocking with Garterbelt, Bewitched, Bayside Shakedown, and Iron Chef, and reference to a range of others, including Mission: Impossible, Friday the 13th, and Marvel Comics' Spider-Man.

The first half of the series featured opening theme {{nihongo|"Change!"|チェンジっ!|Chenji!}} by Kana Adachi, who also portrays a recurring character, and ending theme {{nihongo|"Daijoubu"|大丈夫||"It'll Be Alright"}} by Kana Hanazawa, who occasionally hums the tune in-character as Katrielle.{{Cite web|url=https://www.animenewsnetwork.com/news/2018-03-01/kana-adachi-kana-hanazawa-perform-theme-songs-for-layton-mystery-tanteisha-anime/.128371|title = Kana Adachi, Kana Hanazawa Perform Theme Songs for Layton Mystery Tanteisha Anime}} From the twenty-sixth episode onwards, the opening and ending themes were replaced with {{nihongo|"blooming"|ブルーミング |burūmingu}} by Rei Yasuda and {{nihongo|"Ashita mo, Sekai wa Mawarukara"|明日も、世界は回るから。||"Tomorrow, the World Will Turn"}} by the then-J☆Dee'Z, respectively.

In conjunction with the series, Takara Tomy released a line of "puzzle-solving charm" accessories, usable in the mobile and Switch versions of the original game via near-field communication. As part of their promotion, different charms were featured in Katrielle's outfit both across stories and in an alternating set of variants of the original opening animation. A competition was also held, the goal of which was to design an outfit for Katrielle which would then appear on-screen.
