You died and was brought to the afterlife. Its a post-apocalyptic world where you must survive to get a chance to live again. Get to the Judges Gates and talk to the Goddess of Life and the Goddess of Virtue. Survive monsters out to kill you permanently, meet other survivors, escape the Goddess of Sin or seek guidance and advice from her brother, the God of Death . Do whatever it takes to get that second chance, because there is no heaven in the end. Just hell.
