Studying music at a remote island academy, poor Mayumi (Aki Hoshino) and her classmates fall victim once more to erotic tortures at the hands of their corrupting instructors. Just in time, Kekko Kamen (Misaki Mori) takes center stage with a red mask on her head, nunchakus in her hands, and a song in her heart!

When good-natured Mayumi finds herself at the mercy of her sadistic, panty-crazed teachers, only one brave naked soul is capable of confronting her tormentors -- Kekko Kamen! Wearing nothing but knee-high red boots and a red leather mask, this nunchaku wielding superhero gives these perverts a dose of their own medicine. Wildly cornball and completely over the top, this will have you watching with mouth agape in utter disbelief! Two Nipples Up!
