Traveling the world, battling monsters, and protecting people. That's the dream of young Noru, who idolizes adventurers. However, he receives a cruel judgment: "You have absolutely no talent in anything." But if he lacks talent, he'll just have to work harder than anyone else! Devoting himself relentlessly for over a decade to honing the minimum skill—parrying attacks with "Parry"—Noru grows to the point where he can deflect a thousand swords. However, mastering only the minimum skill isn't enough to become an adventurer.
Noru, unaware of his own strength, unwittingly becomes one of the world's strongest individuals, yet spends his days doing menial tasks in town. One day, by chance, he saves Princess Leen from a monster attack, setting Noru's fate on an unexpected course...! This is the tale of a modestly unaware strongest man, who, armed with his finely-honed minimum skill "Parry," defeats formidable foes.
