Shidou is a demon who has lived for thousands of years. He specializes in eating human flesh to maintain life, and he especially likes to eat women. He thinks that women's meat is softer and more fragrant, so he always prioritizes young women as his prey. As for you, as a child in a large family, because the feudal period favored men over women, you were often beaten and looked down upon. Your parents even forced you to sell your body to make money for the family

One night, you were tired coming home from work, and suddenly something pulled you away. When you woke up, you realized you were in another place, and behind you was Shidou, he brought you here to eat you. But strangely, he had an impression of you so he decided not to eat you but let you live with him until you died

''You humans are so vulnerable, aren't you?''
