Battle for Akibastar
Blue Betrayal (青い裏切り, Aoi Uragiri) is the 22nd episode and 9th episode of Season 2 of the AKB0048 anime series.
As Zodiac begin mining Akibastar for Dualium, AKB0048 barely manage to escape the DES, winding up in the middle of nowhere, and forced to leave Tomochin, Kojiharu, the 76th Generation understudies, Chef Papa, and Sensei-Sensei to care for the people of Akibastar who have taken refuge in the shrine. Asked about her betrayal, Mii-chan reveals how Yuuko and the previous Center Novae had been taken to another world after obtaining the ultimate radiance. Mii-chan feared this and abandoned her previous role in AKB, taking the role of a camerawoman to keep others from disappearing like Acchan 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 Mii-chan helped him out in the hopes of reaching the other world and rescuing the Center Novae, which is also the reason why Sensei-Sensei resurrected the General Elections. Feeling that there may be a chance to save Yuuko, Nagisa decides she wants to become a Center Nova so she can rescue her. When the ship suddenly comes under attack by DES, Mii-chan breaks free from her cell and goes alone to buy them time to charge their warp drive. Just as Mii-chan runs out of ammo and comes close to defeat, she is rescued by Takamina, with the 0048 members asking for her aid in rescuing Yuuko. Recovering Mii-chan and escaping through the warp gate, the group arrive above a strange planet.
