As a Reincarnated Aristocrat, I'll Use My Appraisal Skill to Rise in the World 1

After thirty-five years of perfectly ordinary life, a run-of-the-mill businessman suddenly drops dead...only to be reborn in another world! Now he must live as Ars Louvent, scion of a minor noble family and wielder of a fabulous skill: Appraisal, the power to perceive the strengths and abilities of others at a glance. He'll need it, too, because there are plenty of problems to solve in the Louvent family's territory! Ars only has one choice: recruit the most talented individuals his skill can find, and rise up to new heights in his brand new world!
