現実主義勇者の王国再建記I [Genjitsushugi Yūsha no Ōkoku Saikenki]

In this manga adaptation of Dojyomaru's light novel series, a pragmatic young man is summoned to a fantasy kingdom on the brink of collapse and, rather than slay a demon lord, applies modern administrative and economic reforms to rebuild the failing realm. Published by Overlap since 2018, the series is best known for its methodical, policy-driven approach to isekai storytelling, emphasizing logistics and governance over combat. With 14 issues released so far, it stands out for treating kingdom management as a compelling intellectual challenge.
