Куроно Куруму

Despite this, an often running gag in both series is when she uses her breasts to seduce Tsukune, which, more often than not, makes his nose bleed and causes him to suffocate. She also attempts to use baked sweets laced with love potions to secure his affections, though they never seem to reach him. Also, no matter where they are, she somehow manages to interfere with any tender moment between Tsukune and Moka, often by appearing when least expected. In an omake, Kurumu reveals she has a serious weakness for sweets, to the extent that she once ate poisoned cookies that she made and planned to give to Moka.

The incident seems to have bought her some control over this trait, as the aforementioned love sweets are intact whenever they appear. Described as a tough character, Kurumu sports a pair of bat wings, tail and razor-sharp nails in her true form, and has notable body strength (seen when carrying people during flight). The use of illusions and reality-bending techniques make up for her lack of combat abilities. Kurumu also carries a unique, innate sense of knowing when danger might occur. As of the second manga serialization, she is learning basic witchcraft. Kurumu's mother is Ageha Kurono, who appears during the start of the school festival under the belief that Tsukune is her daughter's fiancé.

Kurumu's power is great even among succubi she is able to glide through mind barriers with ease.
