NINTENDO GAME: Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy
Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy[a] is a puzzle video game developed and published by Level-5. It is the seventh main entry in the Professor Layton series and follows a new protagonist, Katrielle Layton. It was released for Android, iOS, and the Nintendo 3DS, in 2017, and for the Nintendo Switch in Japan in 2018, and worldwide in 2019. A manga adaptation of the game drawn by Hori Oritoka began serialization on March 20, 2018, in Shōgakukan's Ciao magazine, and an anime adaptation, Layton Mystery Tanteisha: Katori no Nazotoki File, began airing on Fuji TV and other channels in April 2018.
The game centers on Katrielle Layton, the daughter of famous archaeologist and puzzle-solver Professor Hershel Layton. With the help of her assistant Ernest Greeves, she solves cases in and around London, alongside a talking dog that, for reasons unknown, only the two of them can understand. Unlike prior Layton games, Mystery Journey has no definitive overarching narrative, with most of its main narrative's premises existing as a basis for a set-up, and being left hanging by the game's conclusion.
