As a Reincarnated Aristocrat, I'll Use My Appraisal Skill to Rise in the World 5 (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.MISDIRECTIONAs the new baron of Lamberg, Ars vows to honor his late father’s wishes by siding with Prince Couran in the Summerforthian war of succession, even as the nearby county of Plena backs Couran’s younger brother, Prince Basmarck. When Ars’s spy intercepts a letter showing that one of Lamberg’s allies is colluding with Plena, House Louvent’s plans are thrown into disarray. But could there be more to this letter than meets the eye?
