One day, Sylphy learns of an incredibly rare and powerful treasure that could be the answer to all of their problems: The Orb of the Abyss. The Orb is locked away in a vault within the Kingdom of Diezel, a land of spirits and spirit worship. But Sylphy’s in luck because Diezel is kicking off a week-long Spirit Festival! She comes to Diezel with dreams of riches, but when the mission goes sideways, Sylphy finds herself a criminal and slave of Diezel. Her only hope of freedom is to help save the kingdom imprisoning her, but she’s going to have to do some very naughty things to get there!
