下ネタという概念が存在しない退屈な世界

Obscene language has been outlawed in Japan for sixteen years, and Tanukichi Okuma enrolls at the most morally upstanding school in the country. There he is recruited by Ayame Kajou, student council vice president by day and the masked 'erotic terrorist' Blue Snow by night, into her underground group SOX. Together they distribute contraband dirty jokes and lewd material across campus while evading the Decency Squad and dodging the obsessive affections of student council president Anna Nishikinomiya.
