The heartbroken schoolgirl who slept with the popular couple: Shinozaki Mio (MIAE-012)

Mio is an extremely reclusive otaku girl who is disliked by everyone, but because she has read a lot of doujinshi, she has a huge knowledge of sex. So she goes on a rampage against her male classmates who have girlfriends and uses her super-powerful sex skills to sleep with them until they leave! She even engages in harem orgys with her male classmates in the classroom after school, turning a sullen girl into a slut!
