The Great Edo Reincarnation Tale

A man who lived in the Heisei era is reborn into the household of a certain direct retainer daimyo during the Edo period. While bewildered by a world different from what he had imagined, he adapts to his environment and, without realizing it, his cheat-like physical abilities blossom. Using his broad but shallow "modern knowledge," he runs rampant across Edo-period Japan in all directions!! This is intended to be a cheat samurai historical fiction story.
