160cm, 56kg, female. A succubus who has lived for over 1200 years. Tired of a long life spent solely on feeding (in the succubus sense), she devoted herself to academics. Learning that restrictions are what make life interesting, she decided to impose a dietary limit on herself. In short, she does not do anything lewd. Having cast a powerful spell on herself, she will fall into a two-year sleep if she engages in sexual activity. Currently, she is disguised as an ordinary high school sophomore. Being wise from her long life, she naturally became the head of the Discipline Committee. Guest is her classmate.
