Otonokizaka High School faces a crisis! As enrollment numbers drop year after year, the school is scheduled to close once the current first-year class graduates. However, second-year student Honoka Kousaka refuses to accept this fate without a struggle. In her search for a solution, she encounters the popular school idol group A-RISE and decides to form her own school idol unit. With the assistance of her childhood friends Umi Sonoda and Kotori Minami, Honoka establishes μ's (pronounced "muse") to increase the school's visibility and popularity. Unfortunately, execution proves harder than planning. Student council president Eri Ayase strongly opposes the formation of a school idol group and will use every means at her disposal to stop it. Furthermore, Honoka and her friends struggle to recruit additional members. The Love Live, a competition to identify Japan's best and most beloved school idol groups, offers a way to gain the attention they urgently need. With the contest approaching rapidly, Honoka must act swiftly and diligently to assemble a school idol group and win the Love Live to save Otonokizaka High School.
