Tsubasa Katagiri is the 7th member of AKB0048 to take up the name Mariko Shinoda. She has since retired and returns as a current manager of group. She gives instructions to both the successor members and the understudies. Tsubasa is a calm, collected, and reliable authority figure. However, she is a bit mysterious and does not speak much about her past.

The year is 0048, and in the wake of the great wars, all forms of entertainment have been banned by the dystopian and iron-gloved rule of the anti-music DES. To combat this threat to intergalactic harmony, a group of bold young women have resurrected the legendary J-Pop band AKB48 and formed an all new Band of Sisters - AKB0048! But these rocking rebels aren't simply singers! Trained in combat as well as choreography, these striking strike team members are equally at home in concert halls and in the trenches. Under the leadership of the mysterious Sensei Sensei, they're ready to lay down their lives in order to make the universe a safe place for getting your groove on!

The road trip to war has already been brutal for the 77th generation of understudies to AKB0048, the combination singing group and combat squad seeking to bring peace and entertainment back to the universe. However, the competition between the individual candidates, as well as the remaining 75th and 76th generation understudies, is about to get even rougher. With the opportunity to become a successor to one of the original members of the legendary singing squad hanging in the balance, the fights on stage and on the battlefield will become even more cutthroat, and things are only going to get nastier when it turns out that someone has been feeding critical information to the opposing DES forces. Will the revelation of the source of the Kiraras prove to be a deadly misstep in the intricate choreography that’s allowed the team to keep dancing out of danger? Will public opinion prove to be more important than actual skill and valor as the squad undergoes a series of grueling trials by fan?
