AKB0048: The Next Generation

This takes place 20 years in the future and entertainment is still banned on most planets. There are new successors, new understudies, new staff, but DES and Zodiac are still after AKB0048. After everyone graduated there weren't as much concerts and people eventually began to forget them. So it's up to the new generation to help the people remember AKB0048 and their songs.
