Tensei Kizoku, Kantei Skill de Nariagaru

An ordinary Japanese office worker dies and is reborn as Ars Louvent, heir to a minor noble family ruling a small domain in an empire strained by inequality and political unrest. Ars has neither overwhelming physical strength nor exceptional magic, but one unusual gift lets him see a person's current abilities and hidden potential at a glance.

Convinced that a major war is approaching, Ars refuses to wait for his territory to collapse. He uses Appraisal to find talented people whom society overlooks because of birth, poverty, or prejudice, then gives them a place where their abilities can flourish. With every new ally, the responsibility of a young noble grows into an effort to build a domain strong enough to survive the coming storm.
