Krampus

Black beastmen with a terrifying appearance that inhabit snowy lands. Despite normally dwelling deep within desolate, snowy mountains, as the “special day” of the winter season approaches, they become very active and start to appear even in other places seeking human men. That's why instead of the men they prey upon encountering them in the snowy mountains, in most cases, it happens in places like far away cities, and they may even suddenly appear at the home of their prey. Their disposition is as ferocious as their looks would suggest, and their speech and behavior are very violent.
