Ever since the 77th generation understudies joined AKB0048, they have been relentlessly attacked by the Deep Galactic Trade Organization and DES.

Unfortunately, their attempts to revert to old tactics in the wake of Acchan's disappearance prove ineffective as a stronger adversary remains hidden in the shadows.
