After losing his grandfather, 19-year-old Kazuya Souma was left with no family members. Suddenly, he found himself transported to Elfrieden Kingdom, a small and struggling country located in another world. As a "hero," Kazuya was summoned by the kingdom's allies to aid in their ongoing war against demon forces that threatened the entire realm. However, instead of engaging in combat, Kazuya decided to focus on revitalizing Elfrieden's economy through administrative reform. Dissatisfied with being used as a tribute, Kazuya took it upon himself to help the kingdom overcome its financial difficulties by implementing new policies and strategies. As a result, he was appointed King of Elfrieden and betrothed to the princess. In order to successfully govern the kingdom, Kazuya assembled a team of talented individuals who would assist him in his administrative endeavors.
