Five years ago, a mysterious phenomenon known as the Global Synchronic Urban Disappearance caused a large chunk of Ikebukuro to disappear overnight. Following the catastrophe, the inhabitants found themselves thrown into a state of disorder, and unexplained electromagnetic anomalies called "Auroras" began to be sighted.

Shortly afterward, she is scouted by a young woman named Kaoru Sakakibara, who turns out to be the director of Alice in Theater—the troupe that Izumi used to be a part of. Aiming to pursue her dreams, Seria decides to follow Kaoru and joins Alice in Theater. Upon arriving at their establishment, she is cordially welcomed by a group of young and friendly girls who are all very passionate about acting. However, something seems to be amiss…

After being forced to graduate from JPX48 following a controversial incident with a male fan, Ai Narata swears to never interact with another man ever again. Using her talents and strong desire to get away from men, Ai auditions for the exclusive all-female Kouka School of Musical and Theatrical Arts. The school is renowned for producing the best actresses that go on to perform in the famous all-female Kouka Theatre Troupe. Coming from the idol industry, Ai is the perfect candidate for the school's hundredth generation class, but her aloof demeanor alienates her from her classmates. The eccentric Sarasa Watanabe is the only person who wishes to become Ai's friend. She enters Kouka with the goal of becoming a top "otokoyaku" performer—an actress that plays traditionally male roles. After seeing a Kouka performance of The Rose of Versailles when she was younger, Sarasa dreams of performing as Lady Oscar one day. Unfortunately, Sarasa's inability to read a room causes friction between her and her classmates, including Ai, who reluctantly becomes her roommate and partner in many of their classes. Succeeding at Kouka will involve more than just raw talent for these young girls as jealousy, deceit, and the harsh realities of show business put their mental fortitude to the test. Will Sarasa and Ai be able to rise to the top and stand on the silver bridge?
