Just as Sakuya comes to rescue Mikoto, Natsuhiko saves her from a robot attack and is gravely injured. As he undergoes recovery, The World informs the ability-users that their decision awaits them tomorrow. If they choose to initiate Reset their powers will be returned to Aion. However, because its powers are deteriorating there might be some side effects, like losing one another and their own memories. Kakeru vows never to forget Koharu. Everyone spends their last day together laughing and sharing sides of their own personality. Instead of next afternoon though, Reset initiates late at night. The teenagers' powers are absorbed into The World's Tower, which sends a burst of powerful energy connecting to Norn9. Travelling around the world, Norn9 gathers the powers from every ability-user to rewrite the world, destroying it completely, and wiping the memories of every human on Earth. Aion lets out its last song before all the forces combine, ravaging the planet.
