Yumenosaki Academy has long been the home of top boy idols from various generations. Wielding significant influence over the school, the student council upholds the status quo by strictly enforcing traditional rules. Transfer student Anzu enrolls as the inaugural member of the production course, becoming the only female student in the entire academy. There, she encounters Subaru Akehoshi, Hokuto Hidaka, Mao Isara, and Makoto Yuuki—her classmates and members of the idol unit "Trickstar." The academy hosts Dream Idol Festivals, stage competitions where students compete in singing and dancing, with the audience voting for the winner. Victory in these "DreFes" grants idol units various privileges and prestige. However, as the student council intervenes to punish anyone involved in unsanctioned DreFes, the members of Trickstar realize they can no longer remain passive. With Anzu serving as their producer, they plan to become revolutionaries within the academy.
