Four years after leaving his teaching post, Ryuudouji Shimon lives quietly in a rundown apartment. One day, he receives an unexpected hiring notice from a famous private girls’ school. Confused but curious, he steps back into the academic world and meets the school’s chairwoman — the alluring Ryuzaki Sayaka, a former colleague.

She presents him with the shocking “Full Life Supporter Development Plan”: an elite program that grooms beautiful, talented girls with exceptional sexual skills and sells them to rich clients under the guise of “employment.” Ryuudouji’s condition for reinstatement is to serve as the instructor and turn four selected students into the ultimate “products.”

Hiding his surging excitement and long-suppressed sadistic desires, he accepts. As he begins breaking in the girls through rigorous slave training, Ryuudouji senses a sinister conspiracy behind the too-perfect offer. In the second part, the training reaches its climax, and even the cunning Ryuudouji finds himself at the mercy of Sayaka’s masterful techniques and her rare, heavenly body.

A dark tale of domination, mind-breaking pleasure, and hidden schemes from the master of intense hentai animation.
