Van, the fourth son of a powerful noble, is only two years old when he remembers his past life as a salaryman in Japan. With his adult brain in a young body, he's considered a child prodigy...until he displays the "Production Magic" skill when he turns eight. In a family that favors offensive magic, this crafting skill is considered useless in battle, and Van is banished to oversee a tiny country town in disgrace. With only his personal maid, his father's butler, a knight, a rescued slave, the memories of his past life, and his "worthless" magic, can Van improve the fortunes of this little village—and himself?

Exiled to a rustic town, Van decides to make the most of it and live an easygoing country life. When he arrives, however, he finds that bandits have attacked the village. He and his friends rescue the townspeople, but their job is far from over. Van will have to use his so-called "useless" magic to fortify and protect his new territory!
