Demon
In Hinduism, demons are called asuras. Patala is thought to be an underground place below the Earth, where humans live. Asura means supernatural beings that were good or bad. People who do evil and horrible things in their lives, by reincarnation, will turn into evil, ghost spirits called Vetalas, Pisand hachas, Bhūtas. The most evil people reincarnate in hell as demons. In Japanese folklore, there are malevolent spirits called oni (鬼), a Japanese word translatable as "demon" in English.
