Does Humanity Need Civilization at the End of the World?

Year XXXX A.D. In this apocalyptic world ruled by "God," humans live as if crawling on the ground. The human race has dwindled to a few people, but in the midst of all this, Kasago blindly believes in "God" and engages in the "civilization recovery" business, taking civilization away from humans as he is commanded to do. On the other hand, Mebaru, which Kasago met on his way to work, does not even try to hide her suspicion of "God". Kasago is looking for his parents, while Mebaru is looking for her parents' killer. They continue their journey of retrieval while coming into contact with "civilization"... This is a mysterious apocalyptic travelogue of the near future!!
