An Isekai, Warring States-esque tale of climbing the ranks.

A thirty-year-old salaryman is reincarnated in another world as Nois.

Although magic existed in that world, Nois, born into a commoner blacksmith's family, possessed almost no magical power.

Through his efforts to increase his magical power, Nois eventually learns to freely control physical enhancement magic.

Before long, he gathers subordinates, forms a secret organization, and in a world much like the Warring States period, Nois climbs his way to the top.
