The Exorcist Series (Lazy Chapter)

No one can tell exactly when creatures that are essentially different from humans and animals and that survive and reproduce in the dark began to appear in the world. This kind of powerful creature, which is not a weapon made by ordinary humans and can withstand destruction, just corresponds to a term imagined by ancient humans, demon. Demons are not physical creatures. They use the temptation of giving humans new powers to parasitize in human bodies. They grow by eroding the fragile human heart and attempt to destroy the original balance of the world. However, the order of the world cannot be determined by demons. A group of humans with strange powers were born in the world. They were born with strange powers that could fight against demons. They were gradually gathered together and became an organization that signed a contract with ordinary humans troubled by demons, and were led by a man named "K". This organization composed of new humans is called "Amber".
