"Forgive me, Raphael."
— Isaac to Raphael just before he disappeared, Rhythm Thief and the Emperor's Treasure

Isaac is a major character in Rhythm Thief and the Emperor's Treasure. He is Raphael's father, but he left his son years ago, leaving him only a coin as a clue. No one knows why Isaac left, so it leaves a lot of questions for Raphael. His story is not revealed during the game.



Three years previously, Isaac seems to have stolen Napoleon's casket and awoke him again. He seems to be now serving him.


At the end of the game, Isaac is shown speaking to the real Napoleon, and that his body must be restored before they can do what they are planning.
