Yumenosaki Academy has housed the top male idols from several eras. The student council, which has enormous power at the school, upholds the current quo by enforcing ancient customs with an iron grip. Anzu, a transfer student, ends up being the inaugural member of the production course, making her the only female student in the whole school. Subaru Akehoshi, Hokuto Hidaka, Mao Isara, and Makoto Yuuki—her classmates and members of the idol group "Trickstar"—meet her there. The academy hosts Dream Idol Festivals, which pit its students' singing and dance abilities against one another, with the public voting to choose the winner. Winning these "DreFes" grants the idol unit members different benefits and reputation. However, with the help of the student council and punishing everyone involved in an unsanctioned DreFes, the members of Trickstar find that they can no longer sit around and let it continue. Alongside Anzu as their producer, they plot to become the revolutionaries of the academy.
