The Rose of Versailles

Oscar! The Destiny of the Rose (1x1)

:

Oscar François de Jarjayes is born. Due to her father's strong desire for a son, she is raised as a boy. At the age of 14, she declines an offer to become Commander of the Royal Guard and watch over Marie Antoinette due to her dislike for "babysitting" and a lingering desire to live as a woman, but she accepts after defeating contender Gerodere in a duel and a fight and talk with her servant and best friend, Andre Grandier. (In the manga, Oscar is promoted to Commander before she graduates from military academy and is proud of this accomplishment, accepting it without worry.)
