In Tokyo's Chiyoda-ku is the traditional school Otonokizaka High. Second year student Kosaka Honoka discovers the school will be closed in three years. In order to avoid being closed, the school must increase its number of prospective students.

The school is threatened to be closed. In order to protect Otonokizaka High, Eli looks for ways to make the open campus a success. When trying to help the group's success, Umi tries to get Eli to teach them how to dance.

Honoka quits being a School Idol after she failed to realize Kotori was suffering. µ's goes on hiatus, and Honoka is left without a goal. Honoka arranges for Umi to meet her, and tells her how she really feels.

Once again μ's begins pursuing the Love Live. Just as they're getting started, a new rule is announced declaring only previously unperformed songs can be sung at the regional preliminaries. In order to write a new song in just under a month, the girls head to the mountains on a camping trip! Naturally, they stay at Maki's cabin.

The Love Live regional preliminaries are just before the girls. Because the group is free to choose any location for their performance, Honoka suggests they perform at school, but Nico and Hanayo insist they cannot win unless they choose a location with greater impact.

The day of the final preliminaries, the second years try to make their way to the event after giving an address from the student council at the school's information session, but their means of transportation are paralyzed due to the snow. The girls try walking through the snow to reach the event, but...

Today is graduation. Having finally finished her farewell address, Honoka heads to school in high spirits. At the gates she meets Rin and her friends. They head to the club room together, where they find a trophy and flag.
