What happens when an accident happens and the result is the dead are given the chance to continue living in another world filled with magic and monsters. They get to start over with their names and memories but out of the total deaths one person has to be reincarnated as a monster that is the cost of them all being reincarnated by the goddesses. I may change the genres or content waring stuff if readers don''''t think it fits the story thx.
