The premise isn't just a joke, it's the entire machine. A world where dirty words are illegal means every obscene act, every crude whisper, every filthy poster becomes genuine rebellion, and the show commits to that logic hard enough that the stupidity becomes genuinely funny. Ayame doesn't just crack jokes; she weaponizes them, and watching her drag an unwilling straight man through increasingly absurd schemes of public indecency has the relentless energy of comedy that knows exactly what it is and refuses to apologize for it. The humor won't land if you're not built for crude, but if you are, there's nothing else quite like watching a show that treats dirty jokes like they're worth going to prison for.

Japan has banned coarse language under a law framed around raising children in a healthy way, and sixteen years later the country has been scrubbed of anything obscene. Citizens wear devices around their necks that let authorities watch for impurity. Tanukichi Okuma, son of a notorious terrorist who fought the chastity laws, enrolls at the nation's top school for public morals and offers to help the student council so he can get closer to its president, Anna Nishikinomiya, his childhood friend and crush. Vice president Ayame Kajou secretly operates as Blue Snow, a masked outlaw who spreads lewd material, and his father's reputation catches her interest. Blackmailed into joining her group SOX, Tanukichi is pushed into spreading obscene propaganda and carrying out indecent acts of terrorism against the government's strict rule. The school is the first target, and he soon learns that the person SOX is aiming at is the one he admires most. Expect crude, raunchy comedy built on ecchi humor.
