When news gets out that the school is going to close due to poor numbers of new students Honoka and several of her friends rally together and form a school Idol group in order to prevent the school from closing.

Honoka Kosaka is a girl who loves her school, Otonokizaka Academy. When the school is planned to be closed down due to a lack of applicants, Honoka becomes determined to save it. Learning that school idols are popular, Honoka and her friends start up a school idol group called "u's" (pronounced muse) in order to attract new students. Once they successfully prevent Otonokizaka Academy from closing, the girls from u's aim for higher grounds and participate in "Love Live", the ultimate school idol competition featuring the best groups in the country.
