I Transmigrated to Another World and Became the Demon King

One day, an ordinary employee suddenly transmigrates to another world, but something about the whole thing seems a little strange.

Isn't the usual thing to become a hero, or get some special class, and go fight the Demon King?

How did I become the Demon King instead? Hey!

What? There are too many heroes, so I can only become the Demon King!

Ah! This is too hard.

This is a story about the Demon King conquering the world, then saving it.
