A type of succubi who have undergone a peculiar development that live in villages called “shinobi villages” deep within mountains and other places people come near. “Kunoichi” were originally human ninja women, but when the mamono lord took over, some of them were changed into succubi, originating the “kunoichi” as monsters. Their wings have atrophied, but compared to the original type, their physical abilities are extremely high, and they excel at swift, agile movement.
