Nerawareta Megami Tenshi Angeltia

Based on the adult game by Syrup: Many Milk. Demons assault the earth, deploying a field that induces uncontrolled lust in men. They then harvest the resulting carnal energy to restore their power. Selected by Suzune-sensei, Yuuri is transformed into an Angel Goddess to combat these dark forces. Once Suzune-sensei judges Yuuri ready to operate independently, the situation deteriorates. The demons now command a new entity powerful enough to defeat an Angel Goddess. Yet the threat extends beyond the possessed men. Yuuri's own gym teacher emerges as a greater and more perverted danger than she imagined. However, she is not the sole individual to have been compromised.
