Tousan wa [Kensei], Kaasan wa [Kenshin], Boku wa [Ochi〇po Chanbara Master]

In a world where every individual receives a divine "Job" at the age of fourteen—a celestial declaration that dictates their talent, societal role, and entire life trajectory—Regulus faces an extraordinary burden. Born to a father renowned as the Sword Saint and a mother celebrated as the Sword God, his pedigree is nothing short of legendary. Yet when the heavens bestow upon him his own vocation, it is not the expected mastery of conventional blades but the utterly bizarre and humiliating title of Penis-Sword Dueling Master. Armed with a skill that defies all martial logic and invites endless mockery, Regulus must navigate a world that judges worth by one's divine calling. As he struggles to find any practical application for his peculiar art, he soon discovers that his "shameful" job may harbor secrets far more potent than anyone—including his legendary parents—could have imagined. What begins as a cruel cosmic joke evolves into a swordsman's saga unlike any other, challenging preconceived notions of strength, destiny, and the true nature of a warrior's spirit.
