Mana Shikimiya enrolls at Marehoshi Academy, known for its mandatory club participation. Led by the Student Council Vice President Minori Hasegawa, Mana explores various clubs before stumbling upon the Lyrical Tradition Dance Club, led by Mizuha Ichikishima and Sayu Tsukisaka. Enchanted by their performances, Mana joins the club, and the trio sets their sights on triumphing in the renowned Prism Stage competition, the pinnacle of idol success in the nation. But their immediate challenge is daunting: the club faces disbandment by the strict student council due to its scant membership and lack of achievements. Determined to save their club and pursue their dreams, Mana and her companions must recruit new members and transform into a formidable idol group capable of not only qualifying for the Prism Stage but also emerging victorious.
