There are six rules that were established so that humans and yokai can co-exist:
You must never harm a human.
You must never show your true form to a human.
You must obey the laws that humans have made.
You must never enchant a human.
You must never have children with a human.
You must never bring a human into yokai territory.
The Minatsuki family has existed peacefully in the human world and has prospered by obeying these rules. This is a story about Airo, the only daughter of the head of the Minatsuki family, the Minatsuki family butler, Raito, and the head maid, Fuuka.
Contrary Airo can't honestly express her feelings and bosses people around. Fuuka has a stiff exterior but can't help teasing whenever she sees an opportunity. This is how they spent their peaceful, everyday life.
One day an incident occurs in the town where they live. Onizou Mitsuki, the head of the household, asks Raito and Fuuka to protect Airo. The two of them must now stay by her side day and night. They accompany her, not just inside of the mansion, but at school as well.
Humans, fairies, dwarfs, and beastmen. Laurencia is a remote island where the four races live happily without conflict.
That peace was brought about after the four tribes united to challenge the "Demon King", who once came from the mainland and ruled the island with fear and despair. They were able to defeat and seal him in after a having won a fierce and painful battle. Several hundred years have passed since then. The threat of the Demon King has been forgotten in the prosperity supported by advanced magic technology.
One day, an earthquake occurs that shakes the entire island. The epicenter of the earthquake is the dungeon called "Zvinga" where the Demon King was sealed. The four tribes fear that this might be a sign of the resurrection of the Demon King. The protagonist, Bernard, a descendant of the mage who created the ward, is ordered to investigate it.
There is a dormitory at a private school for training high-class ladies, where students are trained secretly 'To Serve Men'.
However, one of the students got pregnant during the training.
To prevent this from becoming a scandal, the pregnant student was expelled and the dormitory was shut down in fear of causing another incident. Many years passed and now the decaying building is awaiting demolition.
The protagonist, the bastard child of the accidental pregnancy, negotiates with the current principal of the school using the story he heard from his mother.
He negotiates to reopen the dormitory, and work there as a manager.
He only has one goal in mind.
To drain the slaves he has raised and taste their milk.
So the dormitory known as the 'Mistress Administration Building' has been revived by the protagonist. The building will be transformed into the 'Slave Management Building; where the sounds of schoolgirls being trained and milked will echo throughout the night.
