In the distant future, in a galaxy far, far away, there lived a race of shadowy aliens who made their living running brothels. A massive interstellar brothel fleet that abducted women from other planets, trained them, and turned them into prostitutes. The protagonist is a rookie tentacled alien in that organization named “Ika Smith.” The mission entrusted to him is to secretly invade the frontier of the universe— the sword-and-sorcery planet “Earth”— to “cat” (capture) young women to turn into prostitutes, train them, and ensure the prosperity of the brothel spaceship.
