鬼孕ノ巫女 胎贄 穢レ無キ子壺ヲ惨鬼ニ献グ

Oni. It is the existence that the misunderstanding that is connected to the person's world produces, and insults people and insults.
As long as there is a desire in a person's heart, there is a 'demon Maiden' in order to relieve the threat that exists in the near future.
They survive the fierce struggle and defeat the demons, but they are better than anyone else.
Chihaku, Hoko, and Kikyo's Chihaya three sisters were just a demon maiden who was fascinated by oni through the mission.
They were thoroughly insulted by the people who had become mysterious demons, and those who were reduced in mind and body were finally swallowed by the devils of oni.
