Protagonists and Returning Characters

The central duo of the franchise remains the primary focus of the audio localization. Professor Hershel Layton is once again voiced by Yo Oizumi. Oizumi has been the consistent voice for the character in the Japanese versions of the franchise, maintaining the Professor's calm and gentlemanly demeanor.

Luke Triton, the Professor's self-proclaimed apprentice, is voiced by Mio Imada. This casting choice continues the tradition of the character being voiced by prominent Japanese actresses, bringing a youthful energy to the "New World of Steam" setting. The chemistry between Oizumi and Imada is central to the narrative progression of this adventure-puzzle title.

New Characters and Dual Roles

The cast list for Professor Layton and The New World of Steam reveals several intriguing new characters, most notably the Allinston family. Riho Yoshioka is credited with voicing two distinct characters: Elinora Allinston and Elida Allinston. While the specific relationship between these two characters has not been detailed, the dual casting often suggests twins or characters with a significant narrative connection in the Layton series.

Accompanying them is Bolt Allinson, voiced by Shinya Kote. The slight variation in the spelling of the surname (Allinston vs. Allinson) is noted in official credit listings, though both appear to be central figures in the game's new environment.

Other new additions include:
