Demon House

A small house shaped mamono that used to trick humans into entering it so it could eat them. It used a human like bait to lure people to get close enough for it to snatch them. After the new Demon Lord took over it turned from eating humans to mating with males of the species. They appear on the outskirts of human settlements overnight, they have the appearance of a small home that looks haunted. Once they trap a man he can never leave the house shaped part of her, he will spend the rest of his life being taken care of by her. Even though she and the house is one mamono she is able to leave the protection of it to gather supplies for her husband. They can only travel a few miles from the protection of the house shaped portion.They can not take one step past a certain distance from the the house. The reason they can now leave the main body is because it makes it easier to take care of their husband.
