SHIMONETA: A Boring World Where the Concept of Dirty Jokes Doesn't Exist

After sweeping morality laws take hold, Japan becomes a place where anything deemed obscene is stamped out. Citizens are watched through special devices worn around their necks, and public life is engineered to remain strictly “pure,” no matter how extreme the enforcement becomes.

Tanukichi Okuma, the son of a notorious anti-chastity “terrorist,” starts high school hoping for a quiet life—and a chance to get closer to student council president Anna Nishikinomiya, his childhood friend and longtime crush. His plans derail when vice president Ayame Kajou reveals a hidden life as Blue Snow, a masked outlaw determined to reintroduce dirty jokes and lewd materials to a sheltered society. Singled out because of his family name, Tanukichi is pulled into her group, SOX, and pressured into helping spread obscene propaganda, even as their first battleground becomes the school—and the person he cares about most.
