The Japanese version of The Grim Reaper. Contrary to popular belief, they aren't part of traditional Japanese mythology, but got imported from Europe in the 19th century. Originally used to refer to a single entity featured in the play "Shinigami" (usually translated as "death god," but the word is "kami of death" with its own set of connotations), the term has since evolved to refer to an entire race of Psychopomps in Japanese culture. Or, evil demonic soul eaters. Or, those assigned to kill.
