The era of fighting ended, and the demon realm came to be ruled by its queen.

"The seat of the Queen is succeeded by receiving the seed of the one who is summoned from the human world and holds the demon king's power ."

Under this absolute law, to the demon realm that has undergone advancement not unlike the human realm's, one man, Shinkurou Mikami, is once again summoned.

Thrown into the school to ingrain a culture suited for the queen's husband, the curtains rise for days of erotism and anguish from being milked dry for children by the heroines!
