In human perception, vampires are the embodiment of evil and abandoned by the gods, but their embarrassment is far from that.
As far as pure-blood vampires are concerned, they have human bodies but are afraid of the sun; they have the appearance of angels but are not sacred at all; they have the nature of demons but no powerful magic power. They are excluded from the three realms at the same time and drift in the cracks of darkness.
The only thing they can rely on to survive is the night and blood of the human world.
