Sex Ed 120%

Naoko Tsuji is far from a conventional health instructor. Working at an all-girls school, she finds herself deeply skeptical of the standard sex education curriculum and its ability to prepare young women for the realities of life. Convinced that the status quo leaves critical gaps in students' knowledge, she decides to take matters into her own hands by pushing her lessons well beyond the ordinary limits, amplifying the material to a full one hundred and twenty percent. Fortunately for Tsuji, her unconventional approach is met with remarkable composure by her students. Rather than being scandalized, the class proves to be an unflappable group composed of diverse personalities, including a devoted fan of boys' love media, a lesbian student, and another girl whose greatest passion is simply her pet cat. Together, they create a dynamic classroom environment where no subject is considered off-limits. The resulting comedy transcends cheap humor, offering a genuinely thoughtful exploration of modern intimacy. Through candid discussions on topics ranging from safe practices for same-sex couples and the importance of self-pleasure positivity to bizarre biological facts—such as why sugar gliders possess three vaginas—the series delivers both laughter and meaningful insight. It is an educational experience unlike any other, proving that true learning begins when the bell rings.
