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.
Primal devils are powerful form of devils that embody fears that are known naturally since ancient times and even other devils and fiends fear them. Because of this, they are highly dangerous and never once experienced death.
Devils can make a contract with humans, providing them power in exchange for a sacrifice.
In rare cases, a devil can become fused with a human turning them into a hybrid that can partially transform into a devil and manifest a devil's abilities.
A devil's powers are undone when they die.
Once they die Devils go back to Hell. If they die there they are revived back on the human world, thus they rotate in and out of these two worlds.
