Ushi-Oni

A kind of arachne that only inhabits the Zipangu Region. They possess the upper body of a woman with green skin and the lower body of a spider covered in black hair. They’re one of the monsters feared as “monstrosities” in Zipangu. Even among monsters, their nature is especially ferocious. Tainted with immense desire, thoughts of savagely corrupting and indulging in men are always on their mind. So great is their desirr that their body is always hotly seething. Normally, they live deep in the mountains, but sometimes, ushi oni come down from the mountains and attack human settlements seeking men. At that time, if they find a man who strikes their fancy, they’ll shoot out webbing that is almost like a rope, tie him up, and take him back home deep in the mountains. Then, as if to unleash all the bestial desire that had built up until then, they’ll have "fun" with the man and indulge in essence. No matter how much "fun" they have, their boundless desire is never satisfied. They never get tired in the middle of "fun," and they will keep thrusting their hips against a man relentlessly. Once they’ve gotten a hold of a man, they never show themselves around humans again, secluding themselves in their nests deep in the mountains. They end up spending most of the day doing nothing but devouring their beloved man. they wear a seal, or rather a talisman, It's purpose is to hold back the desires of the Ushi-Oni.
