The Iguro Family are an opportunistic, abusive and rotten family of women that worship the Snake Demon. Some time ago, the Snake Demon and Iguro family members made a pact: the demon would kill people, rob them of their wealth, and give them to the family. The family, in return, produced babies and offered them to the demon (Snake Demon was a picky man-eater that fed only on human infants) as sacrifices. Under this agreement, the Iguro family managed to gather an immense amount of wealth.
