My submission to the Beasts! Volume 2. It’s a classic Japanese Monster. There are many stories about different kinds of ushi-oni, which are incredible creatures that all have a cow’s head. The most common and widespread description is that of a creature with a cow’s head and spider’s body, a gigantic creature the size of several bulls, much larger than humans. Taken from yokaimura.org

Also the gyūki/ushioni sometimes transforms itself into a beautiful woman, as it did in a famous story from Kouchi prefecture. There an ushi-oni lived in a deep mountain pool, along with a great number of fish. One day a rich man from a nearby village came up with a scheme to poison the pool and have all of these delicious fish for himself. The gyūki of course did not appreciate this, and appeared in the man’s dream as a woman, asking him to not go through with his plan, but he ignored this warning and poisoned the pool anyway. Subsequently the woman/cow-demon was seen leaving for better waters, and the man’s house was crushed in a landslide and he was killed. Quoted from obakemono.com
