13 Nights of Darkness

The world now is different and the new apocalypse has come. Just like the story of Noah's Ark, the world experienced a great flood to erase the huge amount of sinners because "God decides to wipe the Earth clean of wickedness"... but this time, it is not the flood that will clean this tainted world. And this time, no life will be spare.
Demons are now walking on the Earth and hunts for a Human with a tainted soul to possess. And once the Human body became a full host, that creature will hunt for its prey... a soul with purity and devour it.
Eros and Rosenda, the twin who works for the Organization of the New Church, wonders the destroyed world to search for the last survivor of the Apocalypse for the sake of bringing back the Humanity they lost. They are granted a superhuman power provided by the Organization to fight off the demons and joining them are Jedidiah and Rem, the descendants of a human breed with fallen Angel. It is now up to them to discover the root of their suffering as to why God let those evil consume the land he created.
