The queen, Oh Lylith, has roused you from your death slumber and will inform you of the guidelines governing your new life in Devildom. Now that you are an incubus, it is your responsibility to go back to the realm of humans and give your queen her mana. When you slide inside sexy maidens’ dreams, you gain that mana by finger-fucking them. You perform this on your first night in the world and keep going back to it to have sex with girls who are fast asleep and gather as much mana as you can for your queen. She will be able to hire additional incubus and you to conduct more mana collection job for her thanks to the mana.
