Isekai Shachou - Maou Gun de Nariagaru!

The president of a board game company suddenly finds himself transported to another world!? And the place he ends up in? A monster-infested land with no humans in sight… It’s an isekai story — but there’s no cheat ability at all! His only weapons are the management skills and business experience he built up in the real world!! To find a way back home, he starts from the very bottom of a strangely corporate-structured Demon Lord’s Army— and sets his sights on becoming the Demon Lord himself to defeat the Hero!?
