Maria-sama ga Miteru 2 – Kibara Kakumei /マリア様がみてる ―黄薔薇革命

Shimazu Yoshino, cousin and “little sister” of  Rosa Foetida en Bouton, Hasekura Rei, has returned her rosary to her “big sister.” Rei is devastated, and Yoshino won’t say why she did it. Yumi finds herself running between the two – and witnessing a revolution as little sisters all over the school return their rosaries!
