Shinji, a 16-year-old teenager from the City of Ghuso, is an ordinary young man. He noticed a massive tower one day as he was going down the street and stopped to look up at the sky. The tower fell between the Earth's continents, and as it did, volcanoes erupted, continents fragmented into islands, and massive tsunamis struck tall skyscrapers. As humanity fell apart, the gates of Hell opened, letting all the demons out. Human minds have been overtaken by despair. God is dead.
