Demon (Hell)

Demons are a supernatural race of beings that reside in Hell.

They were originally an advance race of humans from another world that crossed over to Earth thousands of years ago. They were capable of all kinds of magical feats that many considered to be miracles. They co-existed with the humans of Earth for a time, but the two sides eventually went to war with each other, which resulted in the destruction of their world that would eventually be known as Hell. This change made that world inhospitable and forced the inhabitants to lose their corporeal forms and transform into spiritual beings that resembled black mist in order to survive.

The demons have a caste-system, where as the seven most powerful are regarded at the "King Class" and are the rulers of that world.

The demons had been at war for centuries against the Vatican's secret organization Omnibus (who were comprised of descendants of those that fought alongside the humans of Earth).

After the death of Unknown, many of the demons have possessed Hajime Nagumo's Grim Reaper Golems due to their desire to serve under him after witnessing his power. Currently over 5000 demons from Hell have joined his army.
