Final Battle on Akibastar (決戦アキバスタ, Kessen Akibasuta) is the 21st episode and 8th episode of Season 2 of the AKB0048 anime series.
Yuuko starts practicing beyond dance lessons, which worries her teammates. The next day, during a concert, the troops of Zodiac Corporation reach Akibastar. Mii-chan tells Tsubasa that they are behind an element known as Dualium that is hidden in the temple. To motivate the girls, Mikako turns the battlefield into a concert guerrilla, unknowingly doing exactly what Chieri's father wants. Tsubasa orders the girls to retreat, but Yuuko disobeys and attempts to receive the position of Center Nova. Yuuko ends up creating a large amount of energy, which was intense enough to create the amount of light required to open the gate that will allow them to reach all of the Center Novae who have disappeared. Before Tsubasa or any AKB0048 member are able to take action, Yuuko disappears.
