Salaryman ga Isekai ni Ittara Shitennou ni Natta Hanashi

A fantasy world is ruled by a Demon King and his powerful Four Heavenly Kings. One of these is Uchimura Denosuke, an ordinary office worker who is suddenly taken from his routine life and brought into this world by the Demon King. Unlike others, Uchimura does not receive any special abilities. He must rely solely on his experience as a salaryman to face dangerous tasks in this unfamiliar setting.
