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.

While the second years are away on their school trip, Rin is selected to be the temporary leader. However, instead of living up to the members' recommendations, Rin seems unenthusastic and bewildered. When her opinion as the leader is demanded over a trivial disagreement during practice, she is unable to handle the situation.

μ's is invited to perform as a guest at the Akihabara Halloween event. They need local support to win the Love Live. By putting on a impressive performance, μ's hopes to close the gap between themselves and A-RISE before the final preliminaries.

A physical examination reveals Honoka has gained weight. Umi scolds her for her carelessness, and when she attempts to put on the outfit from the first concert...

When μ’s has trouble agreeing on a song for the final preliminaries, Nozomi suggests writing a love song. The members are shaken by the idea of performing and unfamiliar genre, but Eli is suprisingly supportive.

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...

On their first shrine visit of the year, Honoka and her friends run into A-RISE, who give them words of encouragement for the Love Live. Yes, µ's had won the Tokyo regional final preliminaries. Teams participating in the event can post a catch phrase on their team introduction page.

When Yukiho and Alisa are accepted into Otonokizaka High, the girls discuss the future of μ’s. Nico says idols keep their name even after losing members, but Hanayo says it's not μ’s without all nine members.

When the Love Live ends, so will μ's. The day before the event, the members reach a unanimous decision. As usual, the girls gather on the roof and end their practice amidst a friendly atmosphere, but when they realize it's their last practice together, they find themselves unable to go home and end up spending their last night together at school at Honoka's suggestion.

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.
