In this world, humanity are thought to be the only intellegent beings. However, they are completely wrong. There are another race far more superior compare to human. They are they very embodied of humanity's fear; Devil. The Devils are a race of supernatural entities appearing throughout the world. They are creatures' that feed upon humanity's fears. All of them are born in Hell, and have a "name" which represent what fear they hold. Devil Hunter are human who hunt down Devil in order to fight and kill them. In order to defeat the Devils, human make contract with some of them and use Fiend, Devil that possess human corpse, to fight as well. As both sides continue to struggle, the human side are slowly getting the upperhand. The infamous Chainsaw Man are with them, and even two individual that will be his supporters; the golden beast and two sided bat. (A/N: Chainsaw Man is not belong to me.
