Onryō
In Japanese traditional beliefs and literature, onryō (怨霊, lit. 'vengeful spirit', sometimes rendered "wrathful spirits", "hatred spirits", "resentful spirits", "ruthless spirits", "envious spirits", "dark spirits", "fallen spirits", or "downcast spirits") are a type of ghost (yūrei) believed to be capable of causing harm in the world of the living, injuring or killing enemies, or even causing natural disasters to exact vengeance to "redress" the wrongs it received while alive, then taking their spirits from their dying bodies. Onryō are often depicted as wronged women, who are traumatized, envious, disappointed, bitter, or just infuriated by what happened during life and exact revenge in death.
