As a Reincarnated Aristocrat, I'll Use My Appraisal Skill to Rise in the World 13 (manga)

It's brains over brawn in this new isekai adventure!

One day when leaving work, a salaryman dies and is reborn in another world as the weak child of the noble Louvent family.

Using his "appraisal" skill, which lets him see the stats of others, young Ars Louvent recruits the best people to his side in order to turn his country around.  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?
