Owney

In Japanese mythology, a mountain spirit that looks like an ugly old woman of a very evil appearance, covered from head to toe with long black hair. Friendly to people who treat her respectfully.

At nightfall, she occasionally visits one of the villagers or enters a mountain hut, asking for food and shelter.

If the owners are kind and invite her into the house, then owney will spin a huge number of threads to be enough for the whole family, and then disappears without a trace.
