Based on the adult game by Syrup: Many Milk. Demons are invading Earth, unleashing a magnetic field that plunges men into a state of frenzied lust, thereby absorbing the resulting carnal energy to restore their own strength.
Yuuri is chosen by Suzune-sensei to become a Guardian Angel Goddess to combat these creatures of darkness. However, just as Suzune-sensei deems Yuuri capable of fighting independently, things take a turn for the worse. The demons have engineered a new creature capable of defeating even a Guardian Angel Goddess.
But the demon-possessed men aren’t the only ones who want to claim her; her own physical education teacher turns out to be a threat and a pervert more horrific than anything she could have ever imagined. And Yuuri is not the only one in grave danger…!
