Honoka K¨saka is a girl who attends Otonokizaka Academy. When the school is scheduled to be closed due to a lack of applicants, Honoka becomes determined to save it. Honoka goes to UTX, where her little sister planned to go for high school, and sees a crowd watching a music video of A-Rise.
UTX's school idol group. Learning that school idols are popular, Honoka and her friends follow A-Rise's footsteps and start their own school idol group called ¦Ì's (¥ß¥å©`¥º My¨±zu, pronounced "muse") to attract new students. Once they successfully prevent Otonokizaka Academy from closing, the girls from ¦Ì's set their sights higher. They participate in Love Live, the ultimate school idol competition featuring the best groups in the country. Despite winning the competition, the girls from ¦Ì's disband soon after for their own personal reasons.
