勇者に恋人を奪われ最低職【散財家】になった俺、使った金が何倍にも戻るので赤字支店を世界一の商会都市に変えてしまった

Ren, a poor student whose lover was stolen by a hero and who was abandoned by his academy, was given the lowest possible profession: "Spendthrift," a job neither capable of combat nor production. Everyone laughed at him. However, this profession held an extraordinary power: "Spendthrift Return," where money spent was returned many times over. Moreover, Ren was the sole missing heir to the world's largest trading company, "Black Dragon Trading Company." His treacherous ex-lover. The hero who looked down on Ren. His uncle and the company executives who tested him. Facing them all, Ren doesn't simply throw money around, but discerns its true value, reviving dilapidated branches, discarded talent, failed magical artifacts, and poisoned mines one after another. This is the story of a boy ridiculed for having the weakest profession, who saves the city with his power to circulate money correctly and buys back a future even the hero couldn't protect—a rise to power in another world's trading company. In the end, the one who ruled the market wasn't a hero wielding a sword, but a former poor student holding the ledger. #IsekaiManga #IsekaiAnime #IsekaiReincarnation #NarouStyle #ExileAndRevenge #RevengeStory #WeakestJob #RiseToTheTop #TradingCompanyManagement #MerchantProtagonist #BetrayedByHero #LoverStole #ExGirlfriendRegret #CheatSkill #GoldCoinCheat #Spendthrift #SatisfyingStory #IsekaiFantasy #LightNovel #NovelReading #Let'sBecomeANovelist #MangaVideo #AnimeStyle #BackgroundMusicForWork #IsekaiSatisfying #FromWeakestToStrongest #MerchantCheat #World'sBestTradingCompany #BetrayalAndReversal #IsekaiRiseToTheTop
