Luke is the kid apprentice of the famed Professor Layton. He's still new to both fields, and it shows, but the Professor teaches him both how to be an apt puzzle solver, and a gentleman.
Luke is voiced by Lani Minella in North American versions of the series, and by Maria Darling in the European/Australian versions. Professor Layton VS Phoenix Wright was localized by Nintendo of Europe and was left untouched for the North American release, so Maria Darling voices him in all versions of it.
Requested by October 2018 Patreon raffle winner, Sahgo.
