I'm a Noble on the Brink of Ruin, So I Might as Well Try Mastering Magic (Manga)

Despite many bumps along the road, Liam is pulling his new country into shape. Monsters gather under his command as he churns out one innovation after another using his unparalleled magic genius. Each novel idea spurs on the development of their new town, slowly but surely transforming it into a magic city—one that proves tempting to the neighboring nations. Magic junkie that he is, Liam just wants to dream up more ways to harness the miracle of magic, not learn the ropes of diplomacy as a young country's first leader. But he can't afford to ignore the forces lurking around his domain, whether they come seeking trouble or peace. With his loyal companions and trusty dragon adviser by his side, though, there's nothing he can't do!
