Saving a Weapon Shop from Bankruptcy after the Demon King’s Defeat

The Demon Lord has been defeated, and peace has returned to the world—but with no more battles to fight, adventurers are out of work and weapons shops are drowning in unsold stock. Corio, the son of a struggling merchant, faces ruin as his father collapses and his sickly sister Eni risks being sold into slavery. Just when Corio despairs that their only option is to flee, Eni unveils a miraculous business plan that could save them all. With his childhood friend Kizza, the daughter of an armor dealer, and the sharp-witted moneychanger Frista at his side, Corio throws himself into an unprecedented new venture. But obstacles come one after another, forcing him to risk everything as he rallies shopkeepers, adventurers, and even the Hero himself into his scheme. Source: Seven Seas
