No sooner had Ralph Dawson, the only son of a ducal family, graduated from the academy in the royal capital than his retired parents completely dumped the management of their territory onto him. However, though he possesses no special perks from reincarnation, Ralph leverages his past life's knowledge to demonstrate extraordinary administrative processing skills, swiftly clearing the enormous volume of a lord's duties. Moreover, in this alternate world where entertainment is scarce, he engrosses himself in magic research, and has become such a powerful mage that even the Tower of Sages holds him in high regard.

Since his work finishes far too quickly, Ralph, who finds himself with an abundance of free time every day, realizes there’s no place to grab a quick drink after work. And then, an idea struck him.

"Why don't I just open an izakaya myself?"

Thus, after boldly renovating the first floor of the lord's mansion and roping in maids and orphans who also had time on their hands, the first "Izakaya Lord's Mansion" in this alternate world was born, making full use of his knowledge from a past life.
