Game
Characters and cast
Nine credited characters, voiced by nine Japanese actors and nine English ones. Layton and Luke return; six new faces fill out Steam Bison.
Nine voices, six of them new. LEVEL5 announced the cast in April 2026 with a trailer and an interview, and the character page on the Japanese site pairs every portrait with a voice actor and a short description. This page is that list, translated, with the English cast beside it where LEVEL5 published one.
Two of the new characters share a voice actor, which is not a typo: the twins are played by the same person in both languages.
Nine credited voices
| Character | Japanese voice | English voice | Role |
|---|---|---|---|
| Professor Layton | Yo Oizumi | Christopher Robin Miller | Archaeologist, Gressenheller professor, London's authority on puzzles |
| Luke | Miyu Imada | Lani Minella | Layton's assistant, now living in America, nicknamed "Great Detective Luke" |
| Elinor | Riho Yoshioka | Amber Lee Connors | Younger twin of the Allinston family; kind, and a capable mechanic |
| The elder twin (unnamed on the page) | Riho Yoshioka | Amber Lee Connors | Older twin; studious, training as a stage actress |
| The town's inventor (unnamed) | Mahiro Takasugi | Nic Olsen | Steam Bison's foremost inventor, quiet and trusted |
| The Gilded Council chairman (unnamed) | Shinya Kote | Andy Barnett | Steam Bison's richest man; chairman of the council, mayor in all but name |
| The sheriff (unnamed) | Koichi Yamadera | Caleb Jensen | Hot-blooded sheriff, rides a steam bike |
| Falcon | Akio Otsuka | Arthur Romeo | An eagle who hates being mistaken for a vulture |
| The fortune teller (unnamed) | Mikaela Wako Sato | Kayli Mills | Runs the fortune-telling parlour, keeps track of unsolved puzzles |
Four characters appear on the official page with a portrait, a voice actor and a description but no romanised name in the English text. Descriptions stay descriptions here rather than becoming invented names, which is where fan wikis go wrong on day one.
Layton and Luke, nine years on
Layton is still a Gressenheller professor and still the man London calls when something does not add up. The page's one new detail is domestic: until a year ago he was rarely seen without Luke.
Luke is the bigger change. He lives in America now, moved for his family's work, and he has kept the habit - he solves the small mysteries around town and the locals call him Great Detective Luke. Hence America: Layton is visiting, not investigating at home.
The new faces
Elinor and her sister are the daughters of the Allinston family, the town's wealthy patrons. Elinor is the one with grease on her hands; her sister is the one on stage. LEVEL5 gives them the same voice actor and describes them as opposites, which is the setup for most of the town's comedy.
The inventor, the council chairman and the sheriff fill the town's power structure: the person who builds it, the person who owns it, and the person who polices it. Falcon and the fortune teller sit outside that structure - one collects treasure from the sky, the other keeps a ledger of puzzles nobody has solved yet. That last detail is the most game-mechanical thing on the character page: she is the in-fiction explanation for a puzzle list.
Casting notes
The Japanese cast is the one LEVEL5 announces first, and it is the one the Japanese character page documents. The English voices appear on the English version of the same page, which is how both lists can be given here without guesswork.
LEVEL5 published an interview with the Japanese cast in April 2026 alongside the character update, and a trailer with the same cast; both are linked from the series site's topic list.
The page's own silences
- No ages for any character.
- No confirmation of how large each role is.
- No English names for four of the nine, as noted above.
For voice-actor trivia across the older games, the series wiki is deeper than any single game site can be. This page sticks to what LEVEL5 published for this title.
