DARK †Shitsuraku no Shimai Ningyou†

Set in a medieval kingdom world where the struggle between humans and other races ends with human victory and the oppression of others, this story follows a dark elf who amasses a fortune by supplying humans with peculiar species in the slave trade. Swearing revenge on the elf race that destroyed his homeland, he enslaves elf girls and humiliates them for their race's sins—only to realize it's all a terrible mistake.
