A Long time ago, a curse was cast upon the Rindo family. The curse: the family could only give birth to girls. The only way to temporarily lift the curse was to have a child with someone from the Hizuki family. Once the curse was lifted, it would haunt the family again every 3rd generation. Many years have passed and now, Naoto Rindo will be the unfortunate one. His former fiancé from the Hizuki family has passed away due to a tragic accident and now he must impregnate one of the other four girls from the Hizuki family, however, time is running short. Will he be able to successfully impregnate one of the girls with a boy? Or will the curse ruin his life, forever... ~from anidb

A mansion with a young owner, turns to be just the face of an occult practice on this world. Young ladies are trained to serve well the desires of the man who can pay for it. Brutality and torture are just normal things to this family. Also debts from womans can be paid with just a single word of acceptance to render their bodies to the most barbaric practices. But in the end the excess can have a high cost.
