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

The former company slave who died from overwork was reincarnated as Noctis, a weak lord. Noctis is determined, "I definitely don't want to work because I'm in a different world!" However, the territory is always in poverty due to the monsters attacking from the large forest. He becomes an adult and is endowed with skills, he also has an outlier skill called "enlargement & reduction". Furthermore, the demon attack left the lord and his brother as the only survivors. Noctis, who has a genuine neat temperament, will become the lord to create a "world where you don't have to work" in the future!
