Love Live! School Idol Project

Synopsis

On the day before the concert, Umi starts to get cold feet about performing in front of others. To get her used to other people, Honoka and Kotori get Umi to hand out fliers to help build her confidence. Umi has some reservations about the costume, but Honoka manages to convince her to make sure all their efforts don't go to waste. However, on the day of the concert, no one shows up as all the freshmen are busy checking out the other clubs. Just as Honoka is about to break down over her wasted efforts, a nervous girl named Hanayo Koizumi shows up to see the concert, prompting Honoka to go ahead with the performance, which soon attracts a small, but very much appreciated crowd. When asked by Eli about what they'll do next, Honoka insists they'll keep on performing so they can eventually fill up the auditorium.
