Creatures of myth Wiki

Like kitsunes and many other animals develop into yōkai when they reach a certain age. The weasels, known as itachi, are disconcerting animals. They bring ill omens, and people fear their particular brand of magic. Like most animals-turned-yōkai, they possess shape-shifting abilities in addition to a number of supernatural powers. Itachi are tricksters and pranksters, but generally shy away from interaction with humans. As a result, they are mistrusted and disliked. Itachi calls are also considered to be ill omens. After the yelping cries of a group of itachi are heard, misfortune and despair always follows. Though itachi can transform, they prefer to use other kinds of magic—usually with unfortunate results for their targets.
