The story takes place in a world modeled after (and evidently parodying) that of a generic computer role-playing game. The title character is a catgirl slave named Pink, who belongs to a "hero" named Santa. They are accompanied by an axe-wielding barbarian warrior named Bobo and a female elf mage named (depending on translation) either Pias or Pierce. The series depicts their adventures and sexual escapades as they travel around the world, embarking on various quests.
