After the "Law for Public Order and Morals in Healthy Child-Raising" outlawed vulgar language in the nation, Tanukichi Okuma enrolls in the country's most prestigious institute for moral teachings sixteen years later. There, he is coerced into joining the Anti-Societal Organization (SOX) by Ayame Kajou, its founder. Though Tanukichi has feelings for the skilled student council president Anna, he is compelled to engage in lewd acts of terrorism against her as a member of SOX, due to Ayame's blackmailing tactics.
