NSFWAn epic battle has been taking place for several hundred years between two countries, one of Humans and the other of Dark Elves. The humans hired a group of mercenaries, the titular Kuroinu group (or the Black Dogs in English), to join the fight, but the mercenaries betrayed them to form their own nation: the Sex Empire. And now, the Black Dog army, led by the Villain Protagonist Vault, has begun to conquer every single land, extending their influence and sexually enslaving all of the women available — their specific targets are Olga the Queen of the Dark Elves, her bodyguard Chloe, and the Seven Princess Knights of the Human Realm
