You start playing as an ordinary guy who has no luck in his personal life. One day you are approached by a weird girl with elf ears who introduces herself as a priestess of the goddess Fialla and says that her goddess has a proposal for you. It turns out that the protagonist is a very distant descendant of an alien race that once worshiped her.
Fialla asks you to go with her priestess to the abandoned planet (Calypso 69) where your ancestors lived long ago and do a favor for her. You will also meet netrunner Sylphie, hireling Tananda, and space pirate Miwa who live on the planet for different reasons. Also, the goddess will give MC the amulet of changeability, with the help of which MC will be able to turn into a woman (optional).
The game is femdom oriented.​
