【Congratulations! 600,000 PVs - Rome Wasn't Built in a Day, A Journey of a Thousand Miles Begins with a Single Step】Also published on Kakuyomu and AlphaPolis.

Takeshi Sawamori, an ordinary salaryman with no particular talents beyond his love for history, gets into an accident while on vacation in his hometown and is reincarnated into the Sengoku period.

However, he's a completely minor warlord, and naturally, doesn't appear in any well-known historical games.

He's reincarnated as the eldest son of a retainer to a local provincial lord—one that perhaps even local history enthusiasts would be unfamiliar with. Is he already at a dead end?

Honestly, if it were a famous figure, there would be plenty of historical records, and he might even be able to make use of that knowledge, like in typical time-travel or reincarnation stories. But he knows nothing. Absolutely nothing.

Reincarnated as a super-minor warlord, the former salaryman in his late forties begins his second life—a fight for survival.
