After being presumed dead... the chaos left in the wake of Ben Tennyson and Mikoto Misaka's absence have proved to be a little more than people expected. Now that it's protector is 'gone'.. aliens from all over as well as some of Earth's own villains have set their sights on our third rock from the sun, leaving Rex Salazar and Kuroko Shirai as well as Ben's other remaining friends with their hands full trying to fill in for Ben and Mikoto as Academy City's protectors. To make matters worse.. American Politics takes a startling turn as one of the candidates starts to move against allowing any form of alien life on Earth, making things hard for Helen and the Plumbers based in the United States. Overall it's a scramble to keep things in order after a deadly war, while everyone asks themselves the same question: Are Ben and Mikoto truly dead..? And if not.. where are they!?
