Having seen the Seisho, Siegfeld, and Seiran Play Exchange Program's "The Wartime of Farewells" through to success, Stella and the others have taken a big step forward as Stage Girls. Then, another exchange program begins. The name of their partner school is Romana Drama School. It is a newly established school that was founded five years ago. With the rumors of them snatching up excellent students from exchange programs, they possess a shady history. The play Romana has chosen is Oscar Wilde's "Salome", which was once banned due to its content being deemed radical and degenerate. To play Salome, one must steal others' brilliance and be a pure egoist with infinite desires. Appearing before the bewildered Stella is none other than Mikoto Aragami, her old rival from her time in Munich, Germany... "Stella Takachiho. I will steal everything from you, and play Salome."

Seiran General Art Institute Stage Department Performance Major third years Koharu Yanagi, Suzu Minase, and Hisame Honami aim for greater heights, with Koharu as the chief and Suzu and Hisame as the sub-chiefs. The strict teacher Kyoko Yakumo tells them, "This year's new students won't be easy to deal with." Five students among the first years stand out as soon as school begins: Ruri Shimotsuki and Oto Namioka from the Stage Department Performance Major, and Nanaha Akemitsu, Kei Shidara, and Nagomi Koromoya from the General Studies Department. Many students were roused after seeing them break school regulations and put on a performance in their own style without permission, and the school is abuzz from the event. Koharu and the others are hit with an unexpected shock seeing the girls behave in a way that flatly rejects Seiran General Art Institute's "ideology". In order to find "their reason for being here" and "their true selves", they clash over differing values.

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.
