As a Reincarnated Aristocrat, I'll Use My Appraisal Skill to Rise in the World 2 (light novel)

Ars Louvent isn’t just the heir of a petty barony—he’s also a reincarnated Japanese office worker! He isn’t a fighter, and he doesn’t know the first thing about his new world, but he does have one advantage that’s crucial for anyone who hopes to get by as a lord. Namely, an unprecedented eye for talent, granted to him by his special skill: Appraisal!

Thanks to that skill—and to his lack of consideration for his prospective retainers’ ages and origins—Ars has managed to gather up a formidable team of talented followers. Unfortunately, the empire he lives in is teetering on the brink of civil war. To make matters worse, the cornerstone of House Louvent and Ars’s father, Raven, has passed away at the worst possible moment! Ars has no choice but to take up his father’s mantle, make full use of his retainers’ talents, and protect and expand his territory as war rages around him, lest he lose everything he holds dear!
