Originated from the creature who dwells in the forest in Russian mythology. It looks like a human, but it's so skinny that one can almost see its bones beneath the skin. To hide its identity, it always wears a robe. It looks like an elderly woman at first glance, so it provokes sympathy from people, and then eats them once they've been tricked. So be careful if you ever see a robed elderly woman. Wait? She doesn't wear a robe anymore?
