Rio Teikei

Meikoku Gakuen Jutai Hen

The Shroud... Nijou Academy's principal, who is a fellow teacher of mine, was the one who named the abomination that suddenly attacked the school. It has the ability to transfer otherworldly emanations into this realm. Emanations that feed upon the very life essence of human beings. Regardless of a person's mental fortitude, it eventually lead their minds astry, devoured by their carnal desires. As the academy continued being engulfed within Shroud, Shin Asada tries to save them... through sex. A teacher at a cursed school must impregnate every female on the campus to save them from "The Dark Hour".
