Demons (, Ma?) are defined as:[1]

  • Those existences that, while being of the Laws of Nature (自然の法則, Jizen no Housoku)?), distort the flow of such by the exercise of unnecessary powers.[1]
  • That which gives rise to distortion merely by occurrence. Consequently, they are suppressed by way of exorcism (退魔, taima?) upon identification.​[1]

Not to be confused with Daemons, a more specific variety of existence.


Humans, demons, and heroes exist in a cyclical order of superiorities wherein humans are incapable of defeating demons, demons are defeated by Heroes, and Heroes are regulated by humans.[2]
