Originally just an infrequent theme, the rise of demonic characters and themes have given rise to this subgenre. The term demon does not only encompass literal demon characters. It also extends to other entities such as monsters, beasts, ghosts, and other demon-type figures. The demons present can come from biblical backgrounds or come from Japanese culture. Believe it or not, this category doesn’t just come hand-in-hand with the horror genre; it surprisingly blends well with other genres as well.
