Revolutionary Girl Utena(1997)

"Never lose that strength or nobility, even when you grow up." When Utena was just a child and in the depths of sorrow, she found salvation in those words. They were the words of a prince, who bestowed upon her both a ring and the promise that it would lead her to him again. She never forgot the encounter. Now a teenager, Utena attends the prestigious Ohtori Academy; however, her strong sense of chivalry soon places her at odds with the student council and thrusts her into a series of mysterious and dangerous duels against its members.
