Raphael is the main protagonist in Rhythm Thief and the Emperor's Treasure. He is an eighteen year old student in Paris who leads a double life as a infamous thief at night with his faithful dog Fondue. Raphael is nicknamed "Phantom R", stealing valuable artwork only to return it days later. His father disappeared a few years ago. He meets a young girl named Marie after stealing a bracelet bearing the same symbol as a coin his father left him, and finds that her violin has the symbol on it too after helping to defend her from Napoleon's henchmen.
