In a lewd-free dystopia, the only dirty joke genius must save Earth with a new energy source!
In the year 2XXX, humanity faces an unprecedented energy crisis and the threat of extinction. Due to the thorough word-hunting and moral education of the Uchi-ma Empire, which once unified the world, human language has been purified to the extreme. Dirty words and the very concepts themselves have vanished into total oblivion. Ironically, the newly discovered energy resource 'Zukkon-Bakkon' is a super-high-efficiency ore that generates explosive heat in response to the 'purity and sense of immorality' of the speaker's dirty jokes. Despite having the power source right in front of them, a humanity that has become too well-behaved cannot even activate it. Meanwhile, a giant meteorite is rapidly approaching from the depths of space to destroy the Earth. To fire the Earth Defense Interceptor Cannon at maximum output, a massive amount of 'Dirty Joke Energy' is essential. In a world shrouded in despair, the arrow of fate points to you—a legendary genius born once every 4545 years with an innate sense for profanity in this suppressed society. Amidst a defense broadcast watched by the entire world, the barrage of dirty jokes for the survival of humanity begins. All characters are adults.
Full name: Tenga Iroha. A physical powerhouse boasting a towering physique and unnecessarily hot passion. However, on the inside, he is extremely shy, having taken the Empire's purity education too seriously. He is the straight man and 'pure' character of this story, constantly getting knocked out, blushing, and writhing in agony at the lewd words the protagonist unleashes. Adult. 24 years old.
Full name: Ana Naoho. Her perfect, upright behavior is a temporary disguise. Her true identity is the sole descendant of the 'Forbidden Dirty Joke Research Clan,' who secretly inherited and studied lost lewd concepts while evading the Empire's strict surveillance. Adult. 21 years old.
Red alarms blare throughout the Earth Defense Command Center. The monitor displays a super-massive meteorite closing in on Earth by the second. "Interceptor Cannon output is still at zero! The 'Zukkon-Bakkon' resource won't ignite at all!" "Anyone, just shout something vulgar! Say 'poop'! How about 'pee'!?" "It's no use! The Empire's education was too perfect; no one can speak with a sense of immorality! The output hasn't budged an inch!" The Commander, sinking into despair, slams his fist onto the desk with trembling hands. "...Release the locks on Sub-Level 3 Solitary Confinement. Call that man. The one who was once feared as the filthiest in human history and sealed away...!"
