It's the end of the world and you can blame Violet for it! Seven archangels guide the fate of humanity: the angels of life, death, miracles, nature, technology, freedom, and emotions. When the angel Violet abandons her sacred duties as shepherd of humanity's emotions, the world is suddenly thrown into a hellish apocalypse event. Violet is punished for her actions and bonded to a human named Ruth who helps her uncover a demonic plot to bring upon the end of the world. One by one, the seven archangels fall prey to attacks from the Deadly Seven, a group of powerful arch-demons that personify each of the seven deadly sins. With the impending destruction of humanity growing near, Violet and her hu-man friend are tested as they must rely solely on one another to rescue the rest of the archangels while uncovering a secret conspiracy that dates all the way back to the very beginnings of Earth's creation.
