The Lazy Demon King's Wonderful Life

Transmigrating is one thing, but why did I have to become the Demon King? I can't be bothered being anyone's boss!

Damn it! I absolutely won't give up! My dream is to travel all over this world! I'll give it everything I've got to make it happen!

That's what the protagonist thought, anyway. Before long, a priestess, a powerful contender for the Demon King's throne, an elf, and even an ancient artificial human had all gathered around him. His wish to travel to the human world was also thwarted by the Empress and even the Hero. But even so, the protagonist refused to give up. That's the story.
