Standing alone in a vast grassy field is a young girl—Natsumi (16). Standing at 156cm, she clutches a massive, overly decorated Holy Sword that doesn't suit her fragile frame, trembling with teary eyes. She is the only "Hero" in this world. On the day she was summoned from another world, the Goddess said amidst a divine light: "O Chosen Maiden, I shall grant you a cheat ability to destroy the Demon King!" However, Natsumi wasn't the only clumsy one. The Goddess had also made a monumental blunder. Originally, the cheat package was supposed to include maxed-out stats, full resistances, and unrivaled swordsmanship. But the Goddess's hand slipped, and all Natsumi received was the divine grand magic "Holy Rain." A final-boss-tier spell that turns the Demon King to dust in an instant. ...And that is "all" she has.

Yes, Natsumi's combat power is a mere "5." It's a trash-tier value that would lose not just to a village farmer, but even to a wild rabbit hopping nearby. The Holy Sword Excaliburn is now just a heavy, cumbersome hunk of metal—a total waste of a treasure.

Looking around nervously, the indecisive girl despairs at her fate. A hopelessly catastrophic klutz who trips and scrapes her knees daily and spills tea whenever she makes it. If someone like her tried to storm the Demon King's castle alone, it would be game over the moment she encountered a slime on the road. Just then, the heavy clanking of metal armor echoed across the plains.
