Fallen God

"'Thou shall commit fornication...""Thou shall always be lewd...""Thou shall drown in pleasure...""Thou shall always accept love...""Your lovely voice screaming love is your hymn...""The lust burning in your chest is your faith...""Your slamming hips are your worship...""And your orgasm is your prayer to your God...""Fill your aching emptiness with carnal desires...""And drown in pleasure with he who holds your heart...""Amen.'""- The Commandments of the Fallen God"

The Fallen God is a deity of the Monster Girl Encyclopedia world who has been corrupted by mamono mana, transforming into a monster. Her subordinate lesser divinities have become dark angels and dark valkyries, while her gospel is promulgated to mortals primarily by dark priests. If it were possible, the Fallen God's religion manages to be even more depraved than monster girls usually manage; "They want to thoroughly corrupt men so that they'll come at them and ravish them with endless desire". Although the Fallen God is allied with the Mamono Lord, their agendas do not precisely align; like Zipangu, her monsters do not contribute to the Mamono Army. Instead, they preach a doxa of complete, unrestrained depravity, and delight especially in corrupting prudish or restrained targets.

Monsters who follow the Fallen God consider semen a sacred liquid, and love having it sprayed all over them. This means they tend to wear (if anything) black robes, so that semen shows up better. It also gives them a preference for the Corruption Fruit, improving their ability to absorb essence through the skin. Ironically, it's the disloyal followers that get into the Fallen God's heaven: when they find a man to be their husband, they desert their missionary duties and (somehow) enter the spirit realm of Pandemonium, to fuck forever in a world without time.

The Fallen God can perform a special kind of monsterization by usurping the Chief God's connection with devoted priestesses. This happens in Fallen Maidens to Sasha Folmoon, where she is spoken to by the Fallen God in a religious dream. Although the Fallen God commands the loyalty of the dark valkyries, they "have a business-like attitude when dealing with her", as they consider their husbands to be their true masters.
