APPEARANCE: 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, and instead transforms into a powerful wrathful spirit who seeks vengeance on any and everything it encounters. Onryō appear as they did when they died. Often they were victims of war, catastrophe, betrayal, murder, or suicide, and they usually display wounds or marks indicative of the way they died.
INTERACTIONS: Their motive is always the same: vengeance. Onryō are easily powerful enough to swiftly kill any person; however, they prefer letting the object of their hatred live a long life of torment and suffering, watching those he knows suffer and die. They inflict a terrible curse on the people or places that they haunt. This curse can be transmitted to others through contact like a contagious disease, creating a circle of death or destruction that is far more devastating than any ordinary ghost.
