Grete is Gregor's younger sister. She is the only one in the family with whom Gregor was intimate. At first, she takes it upon herself to clean his room and feed him. With time, however, she loses interest in this and leaves him alone. Grete, who first cared so much for Gregor, is also the first to assert that the family must get rid of him. Gregor had planned to use all his money to send Grete to the Conservatory to study violin, and her playing awakens his humanity.
