After being compelled to leave JPX48 due to a controversial incident involving a male fan, Ai Narata vows never to interact with another man again. Leveraging her talents and a strong desire to distance herself from men, Ai auditions for the exclusive all-female Kouka School of Musical and Theatrical Arts. The school is famous for producing top actresses who go on to perform with the renowned all-female Kouka Theatre Troupe. Hailing from the idol industry, Ai is an ideal candidate for the school's hundredth generation class, yet her aloof demeanor alienates her from her classmates. The eccentric Sarasa Watanabe is the only person who wishes to befriend Ai. She enters Kouka with the aim of becoming a leading "otokoyaku" performer—an actress who plays traditionally male roles. After watching a Kouka production of The Rose of Versailles in her youth, Sarasa dreams of one day performing as Lady Oscar. Unfortunately, Sarasa's inability to read a room causes friction with her classmates, including Ai, who reluctantly becomes her roommate and partner in many of their classes. Succeeding at Kouka requires more than just raw talent for these young girls, as jealousy, deceit, and the harsh realities of show business test their mental fortitude. Will Sarasa and Ai be able to rise to the top and stand on the silver bridge?
