Kosaka discovers Otonokizaka High must increase prospective students or close in three years, an intolerable situation.

Honoka gets permission to hold a concert to bring in more students, but the group soon realises they don't have a song to perform yet.

Honoka's idol group prepares to perform their debut song at their first concert, but Umi starts to worry about performing in front of people.

The girls complete their first concert in an empty auditorium and Honoka tries to recruit Hanayo to the group.

The group, now with enough members, attempts to become an official school club, but they are quickly shut down as there is already an Idol Research Club at the school with a single member.

Nico suggests a singing and dancing contest to decide who is worthy to take up the position of the group's leader.
