Humans who touch forbidden things trigger the doomsday written in the Book of Revelation. Devils with angel wings descend from the sky and devour the products of all civilizations. In order to survive, people from different regions launch salvation plans. In Western Europe controlled by the church, a plan called "Twilight of the Gods" is quietly carried out, and "witches" capable of hunting monsters are born.
At the same time, ancient bloodlines around the world are gradually awakening in the collapsing world. Undead creatures called vampires have occupied a place in this doomsday stage with survival genes that are far superior to humans.
Surging desires permeate the souls of all living things, and life blooms like a flash in the pan at the end of the world... The one who ends all this... Is it an angel or a demon...
