Slave Secretary is an adult game that features mini games and RPG elements combined with sexual content portrayed in the visual novel style. 

You play as a Hunter, who hunts monster for parts, known as Monzema, that are valuable but can only be sold by those licensed. One day, while selling Monzema in the black market, you see a beautiful woman being sold as a slave in the auction. The auctioneers hints to you that this woman used to be the former CEO of a large company dealing with Monzema and is licensed to sell it. You win her at the auction and make a deal with her. If she serves you well, you'll help her get revenge for the people that caused her to be enslaved. 

The story's plot is centered around training your new secretary to be submissive to you, while earning Monzema by hunting monsters and having her deal with the business aspect of your company. Both parts respectively feature progressive mini games featuring upgrades to skills and perks.

As the story progresses, you will even encounter Corporate Battles, which are when corporations send drones to attack and raid your business convoys. You cannot control your drones, but you can upgrade them and see how they perform against the enemy. As your drones get stronger, there will be opportunities to perform attacks and raids yourself, which is a key part of the story in your quest to help your secretary get her revenge.
