"The Holy Woman Rejected for Being a 'Defective Product Who Can Only Deploy Barriers' Realizes She's Actually the World's Greatest [Weapon Craftsman] ~ When I Quietly Sold Weapons Made from Barriers in the Frontier, Before I Knew It, Heroes from Around the World Were Lining Up ~"

"Claire Craft! I'm breaking off our engagement with someone so plain and incompetent that you can only cast 'barriers'! You're being exiled from the country!" Claire, who had protected the nation as the state-appointed Saint, was suddenly told by the First Prince, her fiancé, that he was severing ties with her. For him, who preferred flashy offensive magic, Claire—who steadily maintained weapons and castle walls with invisible barriers—was nothing but "incompetent." But the prince didn't know. That in her previous life, Claire was a former corporate slave who died from overwork at a Japanese black company and was a VRMMO production job addict. And that she possessed the blood of a legendary blacksmith, and truly wanted to quit being a "Saint" and become a "craftsperson" instead! "Exile from the country? Thank you so much! I humbly accept!" Overjoyed, Claire is transported by the prince's malice to an S-rank danger zone called the "Abyss Forest," where she discovers the legendary "All-Purpose Workshop: Happaisai." There, she awakens to "Barrier Smithing"—the ability to physically compress and solidify her only skill, 【Barrier】. "The items in my shop are 'invisible swords' that absolutely never break... but would that be acceptable?" This is the story of a craftsperson scorned as incompetent who creates the world's strongest weapons using game knowledge and barrier magic, and quietly (?) starts a business in the frontier. Meanwhile, the kingdom that exiled her loses its greatest Saint, and in that very moment, all weapons and castle walls throughout the nation crumble to pieces, facing the brink of destruction... but it's already too late.
