WELCOME TO THE SPRAWLING METROPOLIS OF TOKYO, A TOP INTERGALACTIC TOURIST DESTINATION WHERE THE LIVES OF EARTHLINGS AND ALIENS INTERTWINE! When the terrifying alien Hakugin attacked a young Sho Tenkubashi and his little sister many years ago, who was their brave—and mysterious—savior? Was it Akira’s father...or Akira himself, somehow? That answer seems to hold the key to everything, and Sho is determined to uncover what really happened. Meanwhile, all Akira can think about is getting stronger and proving himself as a full-fledged member of the squad, but a spar against Sho teaches him just how far he still has to go! As Akira’s past and present identity grows increasingly enigmatic, will the truth from secrets long buried ever come to light?
