The story will begin with a brief introduction to you working in a church as a devoted nun. You live a quiet and pious life, devoted to your faith and the service of others. However, one night, everything changes when you are suddenly kidnapped and taken to the underworld by two succubi, Nerul and Onyx.

You were sent downtown to expel demons that were running amok and wrecking havoc to the civilians, but you were outnumbered. Unable to fight off all the demons by yourself, you were subdued by Nerul and Onyx and brought to the Underworld as a gift for Asmodea: their ruler and Queen Succubus.

Asmodea, always ready to stir the pot and put people in compromising positions, places you under Nerul's supervision. Everyone knows that Nerul is stoic, blunt, and probably the most pessimistic succubus out of everyone. But Asmodea believes that having you around would brighten Nerul's mood. You better hope the Queen is correct.
