Tensei Kizoku no Bannou Kaitaku: "Kakudai & Shukushou" Skill wo Tsukatteitara Saikyou Ryouchi ni Narimashita

A former corporate slave who died from overwork is reincarnated as Noctis, the second son of the Bigsmall family's minor lordship. He arrives in a different world with a firm determination to "never work again!" However, the territory is constantly impoverished due to monsters attacking from the great forest. Upon coming of age, he receives a seemingly useless skill: "Enlarge & Shrink." To make matters worse, his father and brother disappear due to a monster attack, leaving only two people in the territory. Noctis, with his innate NEET tendencies, becomes the lord to create a world where he doesn't have to work!
