The End (Last Order).Since his defeat, Accelerator is no longer feared by others, though he remains powerful enough to get rid of troublemakers. During the last day of summer vacation, he is approached by a younger Misaka clone capable of showing emotions, who introduces herself as Misaka 20001, nicknamed Last Order, and begins to follow him around, much to his annoyance. Because she is hungry, Accelerator takes Last Order to a restaurant and sees Ao Amai, a former researcher for The Sisters Project, but does not pursue him. As Last Order eats, she converses with Accelerator on the Sisters and how she believes that Accelerator was an unwilling participant of Project Level 6 Shift. Tired of her comments, Accelerator leaves her at the restaurant to confront Kikyō Yoshikawa, a researcher in charge of Project Level 6 Shift. She informs him that Last Order was not created for The Sisters Project but for administrating the Misaka Network and that Amai injected a virus into Last Order, which could spread to the other Sisters and cause them to go berserk and attack humans. To stop the virus before activating by midnight, she gives Accelerator the choice of finding Amai to explain how to stop the virus or returning Last Order to her incubator, so Accelerator chooses the latter.
