One day, Kazuya Soma, who has just lost his grandfather, his last living relative, is suddenly transported to another world as a hero.
He is summoned to Elfrieden, a kingdom reminiscent of medieval Europe.
Kazuya is far from hero material. In fact, he’s just an ordinary young man. However, his rational mind and modern knowledge allow him to come up with many new policies to help restore the kingdom’s flailing financial and political systems.
On the way, Kazuya befriends a group of unique and talented individuals, including Liscia, Elfrieden’s princess, the Dark Elf Aisha, the kingdom’s first warrior, Hakuya, a shrewd young man, Poncho, a glutton, Juna, a diva, and Tomoe, a girl capable of communicating with animals.
This is a fantasy story of domestic politics where the hero uses modern knowledge to rescue a kingdom on the verge of collapse!
