Van, the fourth son of a powerful marquis, is reincarnated with memories of a Japanese salaryman. Despite being a prodigy, he is banished to a frontier village after his "Production Magic" is deemed useless for battle. He uses this magic to transform the village into an impregnable fortress city.

The original Japanese text perfectly captures the nuance of "Okiraku" (easygoing/optimistic). The dialogue flows with a sense of levity that emphasizes Van’s carefree personality. Without the filter of localization, the reader gets a direct line to the artist's intended pacing—the quiet moments of Van simply enjoying a meal or tending to his territory feel genuinely soothing.
