The world will soon be devoured and destroyed by God. Rye, a “Salvager” who retrieves bequests for a living on the edge of the city, is looking for traces of his lost father who disappeared in a wreckage. A giant “first class” shows up far far away from the ruined city. If you can’t defeat it with the white pair of wings and the dark halo, humanity shall be exterminated. In this eroded world, the boy along with his master who wields artificial limbs, challenge the tower to meet the Gods.
