Heisei Naughty Academy

Ten years after their student days, Yamagishi and Ikidomari return to the infamous Harenchi Academy—now an all-girls school—as new teachers. While Yamagishi harbors lewd ambitions to seduce his students, the school is thrown into chaos by absurd antics and a cyborg-enhanced attack. Amidst the madness, Yamagishi reunites with his childhood friend Jubei, rekindling a romance in a setting where the boundaries between teacher and student are happily ignored.
