Toono Tsukasa

As president of the love audit club, Tsukasa has made it her personal mission to ensure all on-campus relationships are approved—or rejected!—in accordance with current gender segregation laws. Despite her dedication to the cause, this black-haired beauty has yet to experience love herself, instead letting her wild imagination read the lewd and obscene into even the most innocent of guy-girl situations. Just as she begins to despair, however, her childhood friend, Shun, transfers to the same academy and agrees to help her research sex and dating—all in the name of science, of course.
