Among the lifeforms exists creatures of fire who have abilities that are on par with the demons. While they call themselves demons, they are not acknowledge as such by the other demons.
Carbon is one of the creatures of fire and since his childhood, he always believed himself to be a demon. He wandered the demon world in hopes to one day become the strongest demon ever.
