Ling-Ling is Fong-Fong's older sister who appears just a chapter after her brother's introduction. Ling-Ling is a Jiang Shi who commands an army of similar beings. Being a Jiang Shi, Ling-Ling is actually dead, as she died due to an illness, and makes this point so clear to others that it becomes her catchphrase.
She can also disembody herself without harm, as shown by her head being removed multiple times in her introductory chapter. She makes it known that unlike the other Jiang Shi she commands, she has free will. Ling-Ling wants to kill Tsukune so that she can make him into a Jiang Shi and add him to her army.
Ling-Ling transfers to Yokai Academy as a third-year student, since no one knows her true age and thus no one can prove that she isn't a third-year student. She is the apprentice of Tohofuhai, and is proficient at his Hogetsu Jigen-To (Moon-Crushing Dimensional Sword) technique.
Comically, when she walks off, she hops, sometimes losing her head.
