Demon Lord Astaroth

Demon Lord Astaroth was the last of his kind and not surprisingly the final boss of the game 'The Demise of Astaroth'. Now one night someone was playing this very game but he has chosen the appearance of Astaroth instead of everyone's favorite Hero , midway in the game a certain pop up emerges in front of him and gives him a choice. A choice which teleports him into an unknown land filled with beings only seen in fantasy or anime to be exact but the most disturbing aspect or a blessed one depending on whom you ask, he becomes Astaroth the Demon Lord.

Now in an unknown land where sword and magic exists so do other things like Dungeons, Adventurer Guilds, races other than humans, what would be his course of action? Would he act like the Demon Lord he is supposed to be? Subjugate every nation, every race and become the ultimate being in this world or would he become a normal guy living a normal life?

So many choices but he can only choose one. Follow his journey into this new world he got isekaied into.
