Zeus

Mankind was destroyed by wars and natural disasters, and the only survivors were Gaia, and her children, Uranus, and Eros. While wandering around the desolate land, soon they come across a dome-shaped facility. There were advanced machines that they had never seen before and vegetation that had already gone extinct. Although they were relieved for a moment, suddenly something mysterious happens...!? A new Greek myth that tells the story of human rebirth.
