Mana Shikimiya has just transferred into Marehoshi Academy, a school which requires each of its students to join one of the many sports or cultural clubs. After a quick tour of most of the clubs by the Student Council Vice President Minori Hasegawa, Mana stumbles upon the Lyrical Tradition Dance Club. There she meets its sole members: Mizuha Ichikishima and Sayu Tsukisaka. Drawn to their singing and dancing, Mana joins the club and together they work towards their dream of winning the Prism Stage—a national competition to determine the top idols of the country.
