Japanator: "Taking place in the not too distant future, humanity has been infected with giant bugs called Gastrea. These bugs attack humans and infect them with a virus which then turns the victims into giant bugs themselves. There is no cure. The only defense that humans have against these attacks are cursed children: young girls who were infected with the virus while still in the womb. These girls are born with superhuman physical capabilities and are able to fight off the Gastrea, with the help of their 'promoters,' or normal humans who keep them in check. This series is about one such pairing: a loli is named Enju and her promoter Satomi Rentaro, who lost his parents ten years earlier in a great war."
