Sex Ed 120% (Vol. 1)

Sex Ed 120% Vol. 1 is an educational and empowering manga that blends humor, realism, and sincerity to deliver a fresh take on high school life and health education. Written by Kikiki Tataki and illustrated by Hotomura, this series focuses on Ms. Tsuji, a spirited and unconventional teacher who refuses to let outdated norms prevent her from giving her students the knowledge they need.

Set in an all-girls’ high school, the manga follows Ms. Tsuji as she takes sex education beyond the textbook—covering everything from anatomy, menstruation, contraception, LGBTQ+ topics, pleasure, consent, and more. Her open, confident approach shocks her students at first, but quickly earns their respect and interest. Through a variety of situations—some awkward, some hilarious—the girls begin to ask questions, explore their identities, and support one another.

This manga doesn’t shy away from real issues teens face but presents them in a way that is inclusive, light-hearted, and deeply empowering.
