The Stingy Noble's Maintenance Manual for Another World

A humble nobleman who was reincarnated into another world. Due to poverty in my previous life, I developed a stingy and frugal character in this life. Adhering to the concept of "never waste", I awakened a unique special skill. He is inexplicably loved by his family and friends. Even though I am often misunderstood by people around me, I can always solve various problems that come my way. Unknowingly, he was even dubbed the "Noble Phantasm Iron Rooster".
