Maria-sama ga Miteru's story revolves around the students of the Lillian Catholic school for girls, and can be considered character-driven, focusing on interactions between the characters rather than any sort of ongoing plot or goal to attain. At Lillian Girls' School, there is a tradition known as the sœur system (sœur being French for "sister"), in which a second, or third-year student, the grande sœur ("big sister"), will give her rosary to a junior student, the petite sœur ("little sister"), and promise to look after them and guide them.
