A salaryman suffers a heart attack and is reborn in another world as Ars Louvent, the child of an aristocratic house. Though lacking in physical strength, Ars has a unique "appraisal" skill that lets him see other people's stats and latent abilities. He puts this skill to the test by discovering a downtrodden young man with fearsome blade skills and a street urchin with a knack for magic.

Has Ars found the diamonds in the rough that will help him secure his family's fortunes - and to turn his country around?
