Shimoneta: A Boring World Where the Concept of Dirty Jokes Doesn’t Exist
Light novel series written by Akagi Hirotaka and illustrated by Shimotsuki Eito. Adapted into a 2014 manga and 2015 anime series.
In a dystopian future, Japanese authorities are cracking down on anyone caught using any risque language or distributing lewd materials in the country, to the point where all citizens are forced to wear high-tech chokers analyzing their every spoken word. A new high-school student named Okuma Tanukichi enters the country's leading elite "public morals school" to reunite with his crush and student council President, Anna Nishikinomiya. However, Tanukichi quickly finds himself entwined with the perverted terrorist "Blue Snow" when she kidnaps and forces him to join her organization, "SOX," in spreading semi-pornographic material across the city.
