Maybe we don't exist...

How do you prove that you exist...? Early in the story, Vivi is shy and gullible, almost to a fault. Often stumbling over his speech and lacking in self belief, he is afraid to use his magic to save his friends, believing himself incapable. During the game his personality develops and he gains self confidence and bravery in the face of danger. Despite his new-found confidence, Vivi still questions his existence during the story's course.
