Nagisa, Chieri and Orine manage to evade capture until they are rescued by the WOTA, who offer to help Nagisa rescue her father. Arriving at the detention center, Kanata and Yūka join the WOTA forces in diversionary tactics while the rest of the understudies sneak in underground. However, Nagisa's father refuses to be rescued and they are forced to retreat empty handed. While recouping at Yūka's family restaurant, Nagisa hears from Yūka's parents how her father was arrested because he didn't want Nagisa to be forced to quit AKB0048. Due to all the stress she has been feeling, Nagisa ends up losing her voice, so Chieri decides to fill in for her song. Meanwhile, Minami confesses to Yūko that she intends to graduate after the concert, while Chieri tells Nagisa not to think about quitting until after their performance. As the day of the concert comes, the understudies start their performance while the successors and WOTA defend against the DES, although the concert is cut short due to the overwhelming DES forces. As Yūka says goodbye to Mamoru, who confessed his love for her before the concert, a new Kirara appears.
