|Other Names||Miss Stone|
Rosetta is a passionate student and her flirtatious ways seem to scare Professor Layton. She can be found outside Gressenheller University, quick to greet the Professor and the team. She is currently researching the "Relic Stone of Cornwall", a project in which Professor Layton set for her. She appears various times in the game's credits.
Rosetta wears a tan suit with a black top underneath. She has strawberry blonde hair.
Rosetta's personality can be deemed as too enthusiastic, which resulted in being labelled as a "maneater" by Luke during the middle stages of the game.
Rosetta gives the following puzzles in Professor Layton and the Unwound Future:
"Rosetta is a student of Professor Layton's who is rather enamored with her teacher. She is very passionate and even goes out to dig sites on her days off. Her unusual forwardness causes confusion to many, including Layton himself."
