In both mangas, you can get something inhumane and unrealistic, but at a price. It starts off free, but because of the female's greediness, she asks for more, and all ends up tragic. Both have a creepy salesman, who convinces the females to get what they offer. However, Ningyou Saisei Koujou is much more tragic in the end and much more disturbing.
