Demons

Originally just a theme, the demons genre rose to its ranks because of the rising fame of demon characters and other demon-like elements. As the term demon not only just encompasses literal demon characters, it also extends to other entities such as monsters, beasts, ghosts, and other demon-kind. Believe it or not, this category doesn’t just come hand-in-hand with the horror genre; it surprisingly blends well with the other genres as well (as proven by the huge and ever-increasing number of manga in the demons genre).
