Because every time a Demon King is killed, another rises to take his (or her) place.


 * SPOILERS*

The current Demon King is actually a reincarnated Japanese who defeated the previous Demon King and claimed the title for himself.

The Megimin spinoff novels even reveal that her original motive for defeating the Demon King was not just so she would be recognized as the greatest mage, but so she could become the next Demon King and conquer the world.
