Siegfeld Institute of Music Junior High. An educational institution established for the purpose of training Rohedelstein, the future candidates for the roles of Edels. Two transfer students from Germany are due to enrol in the Junior High. One is Stella Takachiho, whose heritage is descended from Siegfeld's own prestigious family. The other is Shiro Ogami, Stella's exclusive maid. With the pair's transfer comes a drastic change in the fates of fellow Junior High students Ryoko Kobato, Minku Umibe, and Kuina Moriyasu. Liu Mei Fan works hard to meet the expectations of Akira Yukishiro and Michiru Otori, who are searching for a stage girl to carry Siegfeld on their backs. The ones who must entrust it, and the ones who must be entrusted with it—the symbol of the noble king, "Regalia", will end up...

Seisho Music Academy, Siegfeld Institute of Music, and Seiran General Art Institute are to put on a play as part of an exchange program between the three schools. With Yachiyo supervising Siegfeld, she and the five middle schoolers meet with Claudine, Futaba, and Suzu. The play they will be performing is Seisho's popular program "The Wartime of Farewells". As it had been previously revived with Kaoruko and Maya in the lead roles, Claudine and Futaba participate with an extraordinary resolve; meanwhile, Suzu gains a keen interest in Siegfeld's newborn raw gems. Following Regalia, each of them has taken a step forward as a Stage Girl, but Shiro alone remains without a reason to stand on stage. Shiro has been a servant of the Siegfeld family since childhood, and has lived her life solely for Stella's sake, giving everything up for her. However, her reason of being is shaken up once a camaraderie between Stella and Ryoko starts to develop after their revue.
