In the Harry Potter series, Hermione Granger does not undergo a physical transformation from a girl to a woman. However, as the series progresses, she matures and grows into a more capable and confident young woman. Her character development can be seen throughout the books, particularly in her leadership role within Dumbledore's Army, her bravery during various dangerous situations, and her dedication to her studies. While Hermione's transition from girlhood to womanhood is not explicitly depicted, her growth as a character is a significant aspect of her journey in the series.
