The Layton Detective Agency, a business that helps its clients solve unusual mysteries, is run by Katrielle Layton—daughter of the world-renowned archaeology professor Hershel Layton. Together with her assistant Noah Montoir and talking dog Sherl, Katrielle finds herself unraveling cases involving a newly purchased cursed house, a dress imbued with a "demon's curse," and the zombie of a client's deceased spouse, just to name a few.

Aside from her more quirky cases, Katrielle has been working on another unsolved problem: the disappearance of her father. Founding the agency was only the first step in her attempt to uncover the truth behind his vanishing. As she continues to take on client after client, each with wackier and stranger issues to tackle, Katrielle steadily closes in on the answer to the biggest mystery of her life.

[Written by MAL Rewrite]


Based on Level 5's Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy game.

As someone that has closely followed the Layton games for several years, the idea of a Layton anime series excited me. Though, I was a bit skeptical about watching it at first because I was mixed about 3DS Katrielle Layton game and its lack of proper closure to the main story. I watched and closely followed the series in the second half of 2018. The Katrielle Layton anime slowly became a source of happiness as I binged more of the episodes, eventually following the series week-by-week. This review is written from the perspective of a Layton fan, so some of the things I say might ...

As a child I played through all of the Professor Layton games and as you can imagine my overall reaction to finding this series would be the same as any returning Layton fan.

Personally i believe this series does more than justice to the charm and delight of the Layton games.

The art remains the same, keeping the beautiful hand-drawn effect and the soundtrack keeps the same essence as the old but with touches of new aspects, enough to keep the ost from sounding boring and a staright rip from the games.

The plot similar to the Layton games themselves doesnt focus on a in-depth story, in in ...

As somebody who grew up with Curious Village as well as continued with all other 5 subsequent Professor Layton titles and the movie, this was a blast! There's a lot of average stuff in here but I definitely recommend watching the cases adapted from the game as well as the Relic's Treasure mini series which is related to the most recognizable characters in the series. Definitely a ton of interesting mysteries are featured and the art style is pretty good too. I think any fan of the Professor Layton franchise will enjoy watching this, especially the Relic's Treasure subseries within the story.
