Following a meeting with Sensei-Sensei, Tsubasa announces a gravure shoot for all the members, including the understudies. As they arrive on the ocean planet Atamistar, Makoto grows concerned about her appearance, so Suzuko uses a technique to push all the fat up to her breasts. Meanwhile, Yūko confronts Tsubasa, who was a former AKB successor, about the reason why Atsuko disappeared and the center position was abolished, but gets no answers. As Makoto's plan ultimately fails after being stun by a jellyfish, the Kirara glows brightly when Nagisa and Chieri are shot together. As Suzuko explains to Makoto about how she'd rather be an administration member than a successor, Chieri tells Nagisa that she thinks Kirara has chosen her. Meanwhile, Tsubasa meets up with the camerawoman, the former successor of Minami Minegishi and a former Center Nova, who shows Tsubasa the picture of Kirara glowing for Chieri and Nagisa. Tsubasa is satisfied for this, but Minami declares she is against the idea of the Center Nova position being resurrected.
