"The World Decided by 1D100" Prologue Arcadia—a world created by the gods. In this world, innate talent, the power of heroes, and the strength of demon lords are all determined by a 1D100 roll. At the age of 15, everyone undergoes the "Rite of Divine Granting" at a temple to determine their ability scores. Strength, Agility, Constitution, Intelligence, Spirit, Luck. Those values are "talents granted by God" that never change for a lifetime. Whenever an action is taken, a check is always performed. Success if equal to or below the score. Failure if above. And— A roll of 1 is a miracle. A roll of 100 is a calamity. Even a hero will drop their sword if they roll a 100, and even a farmer can slay a dragon if they roll a 1. That is why people say: "The most terrifying enemy in the world is not the Demon Lord. It is the Fumble." In such a world, a young boy (or girl) faces their Rite of Divine Granting. On that day, when everyone expected a mediocre life, the "Dice of Fate" placed in the temple will determine your stats. From 그 moment, a story that will shake the fate of the world begins. Will the protagonist be a mere puppet of the dice? Or— Will they become the one to overturn fate itself? The Dice of Fate (1D100) will always appear before your journey begins.
