As a Reincarnated Aristocrat, I'll Use My Appraisal Skill to Rise in the World 2 (manga) by Natsumi Inoue

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.

ROSELL KISCHA.

After his uneventful life gets cut short, a salaryman is reborn in another world as the child aristocrat Ars Louvent. Using his unique “appraisal” skill, Ars discovers and recruits a fledgling swordsman named Rietz and a girl named Charlotte with a gift for magic. However, Ars’s small domain will need even more talented people if it is to survive—which is why a shy, young bookworm with an extraordinary intellect might be just what Ars is looking for!
