Since its inception by the Nishiki family—a longstanding powerhouse in the local area—St. Martius Academy has served as a center of education for myriad sex slaves, both past and present.

When Ryunosuke Kokuto receives a personal invitation from the chairman of this respected edifice to serve as a professor, he doesn’t say no to the opportunity.

His mission? To plunge the beautiful women listed by his new boss into a life of depraved sexual servitude. His methods are his own to choose and will not be questioned within the academy’s walls.

It’s time to lay bare the lewd and lustful qualities that lurk inside each of these innocent maidens...!
