Devils (悪魔, Akuma or デビル, Debiru) are a race of supernatural creatures that exist throughout the world. Some are extremely hostile and became hated enemies to humans and very seldom work with one another. The more human in appearance a devil becomes, the less animosity towards humans the devil in questions shows; most known are capable of communicating.
Devils are originated from Hell. When a devil is born, it is given a name. The more that name is feared the more powerful the devil is. If a devil dies in Hell, they come to the human world. Once they die, devils go back to Hell. Thus they rotate in and out of these two worlds which effectively makes them immortal. According to Angel Devil, the only thing the Devils remember back from Hell is the sound of chainsaw buzzing.
