Kurumu Kurono is a Succubus and a third year student at Yōkai Academy where one of her goals was to take Tsukune Aono from Moka Akashiya.

Almost the literal spitting image of Ageha Kurono (Kurumu's mother), Kurumu has shoulder-length light ocean blue hair that is tied in a ponytail with a purple maid headband that has one gold star on the left side, deep purple eyes, thick long black eyelashes and large breasts, in which she takes great pride in her big chest.
