Modern Human Lord in Another World MHLIAW

Demon Lord in the modern earth? Well, How about a Human Lord reincarnation to another world? Born in 1880-08-18, he’s a living legend, the one who starts world wars, the one who invented nuclear weapons, the one who advanced technologies behind the scenes, the one who manipulates organisations, the one who really controls the world. And now in 2020 he succeeded in his goal and got to another world? Moreover a fantasy plus medieval one? (Come watch the other world get rekt by our Lord!)
