Maria-sama ga Miteru

At Lillian Girls' Academy, older students guide younger ones through a formal sisterhood tradition. Yumi Fukuzawa never expects to be chosen by Sachiko Ogasawara, the poised senior she has admired from a distance, as her younger sister.

The invitation draws Yumi into the student council's close-knit relationships, where elegant appearances conceal private worries and misunderstandings. Friendship, jealousy, and the fear of disappointing someone important teach her that genuine closeness depends less on perfection than on honesty and trust.
