黒魔術
Black magic has traditionally referred to the use of supernatural powers or magic for evil and selfish purposes. With respect to the left-hand path and right-hand path dichotomy, black magic is the malicious, left-hand counterpart of the benevolent white magic. In modern times, some find that the definition of black magic has been convoluted by people who define magic or ritualistic practices that they disapprove of as black magic.
