Onryō
In traditional beliefs of Japan and in literature, onryō (怨霊, literally "vengeful spirit", sometimes rendered "wrathful spirit") refers to a ghost ( yūrei) believed capable of causing harm in the world of the living, harming or killing enemies, or even causing natural disasters to exact vengeance to redress the wrongs it received while alive then takes their spirits from their dying bodies.
The term overlaps somewhat with , except that in the cult of the goryō, the acting agent need not necessarily be a wrathful spirit.
