One day, the president of a board game company suddenly finds himself transported to another world! To make matters worse, he's landed in a monster-controlled territory without another human in sight. Despite being sent to another world, he hasn't been blessed with any convenient cheat abilities. All he has to rely on are the business management skills and experience he gained in his previous life! Determined to find a way back home, he starts from the very bottom of the Demon King's Army, which, for some reason, is organized just like a corporation. His goal? Climb the corporate ladder, become the Demon King himself, and defeat the Hero!
