At an inconspicuous university in the heart of Japan, a strange evil lurks, fostered by the professors and staff who are practicing a dark religion. Devoted to depravity, the staff`s incantations also control the lusts of the students, who respond by engaging in open acts of perverse sexuality. Only the school nurse seems to have a remedy for this villainous usurping of the student body`s desires, as her intimate counseling sessions with the female students seem to be forming a burgeoning counter movement to take back the school from the influence of evil magic.
