Anime Video - Neareta Megami Tenshi Angeltia 4

Based on the adult game by Syrup: Many Milk. Demons are attacking the world, releasing a field that causes men to have uncontrollable passion and absorbing the resulting carnal energy to replenish their strength. Suzune-sensei chooses Yuuri to become an Angel Goddess and combat these dark things. Things start to go horribly wrong when Suzune-sensei declares Yuuri capable of fighting on her own. A new demon has emerged, capable of defeating even an Angel Goddess. But the possessed men aren't the only ones after her, and her gym teacher turns out to be a far more dangerous and perverted threat than she could have imagined. But she isn't the only one who has been tainted...!
