Prim, proper and very beautiful, Shimako is the most admired of the first-years. She is the petite soeur of Satō Sei at the beginning of the story and later her successor. Underneath Shimako's quiet, mannerly exterior lies a surprisingly strong resolve. However, Shimako is perhaps the most gentle of the three girls of her year in the Yamayurikai. <br /> <br /> In the first season, Shimako is Rosa Gigantea en bouton, her grande soeur being Satou Sei. <br /> <br /> In the second season, Shimako becomes Rosa Gigantea, her petite soeur being Nijou Noriko. <br /> <br /> (Source: Wikipedia)<br /><br />
