Okiraku Ryoushu no Tanoshii Ryouchi Bouei: Seisan-kei Majutsu de Na mo na Kimura wo Saikyou no Jousai Toshi ni

A noble's fourth son recalls his past life as a Japanese salaryman at age two, possessing an adult mind in a child's body. Recognized as a prodigy, his status changes when he develops the "Production Magic" ability at eight. In a family that values offensive magic, his crafting skill is seen as ineffective for combat, leading to his exile to manage a small rural town. With only his maid, his past-life memories, and his so-called useless magic, he seeks to improve both the village and his own circumstances.
