The second season opens with the arrival of the spring term at Lillian Girls' Academy. Students are reunited, but for the Yamayuri Council it is a bittersweet time. While Yoko, Eriko, and Sei are busy preparing to leave Lillian, Sachiko, Rei, and Shimako focus on making sure their dear sisters receive a memorable commencement. Sei’s departure will leave a sizable hole in the White Roses, and filling it will not be easy. The season ends on a note of hope, could anyone appeal to Shimako enough to become the next Rosa Gigantea en bouton?
