Saikyou no Shuzoku ga Ningen datta Ken

Elf? Dwarf? No! Humans are the strongest! I was summoned to a different world where humans are the strongest living beings. In my previous world I was just a normal everyday salaryman, but in this new world, I seem to have become a rare existence. I, who have obtained the strongest power through my race, have decided to enjoy this seemingly stress-free life to the fullest.
