Onryō

Type - Ghost

怨霊

The most dreaded type of yūrei is the onryō. They are the ghosts of people who died with such strong passions—jealousy, rage, or hatred—that their soul is unable to pass on. Instead, they transform into powerful, wrathful spirits who seek vengeance on everything they encounter. Often they were victims of war, catastrophe, betrayal, murder, or suicide—and they display wounds or marks indicative of the way they died.
