Vengeful Ghosts gathers two ghosts whose defining trait is doing harm to the living out of grievance, one Japanese and one South Asian.
An onryo is a vengeful ghost, a Japanese dead person whose grievance is strong enough to bring harm to the living and sometimes to a whole province. The classic cases are political: Sugawara no Michizane, exiled and dead in 903, was blamed for lightning and epidemics in the capital until he was enshrined and given divine rank. That pattern, settling a dangerous spirit by enshrining it, is the goryo cult, and it shows the line between an angry ghost and a god being crossed by ritual rather than by any change in the spirit's own nature.
The churel is a female ghost of South Asian folklore, held to be the spirit of a woman who died in childbirth or pregnancy, or who was badly used by her husband and his family. She is described with feet turned backwards and is said to appear as a beautiful woman to draw young men away. Burial customs recorded across northern India and Pakistan were meant to stop her returning, and the belief is held across Hindu, Muslim and Sikh communities alike rather than belonging to any one of them.
Both figures originate in a specific wrong done to the dead person while living, exile and death in disgrace on one side, death in childbirth on the other, rather than in any general capacity for malice, and both prompted concrete ritual response from the communities that feared them. The onryo's grievance can, in the right ritual conditions, be resolved into something closer to worship; the churel's remains a danger to be warded off rather than settled.
