“Wouldn't being a wealthy commoner be the best option?” After being reincarnated from a hard-charging career in the trading business, Sara finds herself plotting her future from within the marquis's household that has taken her in. If she remains an unwelcome guest, the best she can hope for is becoming some nobleman's second wife, forever looked down upon for her commoner origins. Her solution? Take full advantage of the backing of her wealthy new family while making a strategic retreat to their remote territory, where she can quietly build up enough capital to strike out on her own. At least, that was the plan… When Sara arrives, she discovers that embezzlement has pushed the territory to the brink of financial ruin! With her all-important patron in trouble, there's no point in playing the sweet, innocent little girl anymore. Using long-forgotten alchemical research buried in the castle as leverage, Sara begins headhunting talented personnel. She pressures the guild into developing the local mines to secure a new source of income, all while throwing the adults around her completely off balance as she works to rebuild the territory's economy. And before long, at only eight years old, Sara is already setting out on the path to building a mercantile empire powerful enough to have even a marquis at her beck and call! Family, adults, nobles—it doesn't matter who stands in her way. Armed with a sharp business mind and an eye for profit, this merchant heiress is ready to make a fortune!(Source: Hanashi Media)
