As Zodiac begin mining Akibastar for Dualium, AKB0048 barely manage to escape the DES, winding up in the middle of nowhere. Asked about her betrayal, Mikako reveals how Yūko and the previous Center Novae had been taken to another world after obtaining the ultimate radiance. Mikako feared this and abandoned her previous role in AKB, taking the role of a camerawoman to keep others from disappearing like Atsuko did. She then goes on to explain how Chieri's father wanted to capture AKB to use them and the Kirara for military purposes. Tsubasa then explains that Mikako helped him out in the hopes of reaching the other world and rescuing the Center Novae, which is also the reason why Sensei-Sensei ressurected the General Elections. Feeling that there may be a chance to save Yūko, Nagisa decides she wants to become a Center Nova so she can rescue her. When the ship suddenly comes under attack by DES, Mikako breaks free from her cell and goes alone to buy them time to charge their warp drive. Just as Mikako runs out of ammo and comes close to defeat, she is rescued by Minami, with AKB asking for her aid in rescuing Yūko. Recovering Mikako and escaping through the warp gate, the group arrive above a strange planet.
